Razor Savers FS

[Jblk9695]

Razor Savers to mount on the front of your Razor motor that has stripped threads. I have them in the same diameter as the Razor or in a diameter to just fit inside a GWS 300 gearbox(thanks to a suggestion from Rob Butler). Both versions come with 3 M2 flathead screws to mount the Razor Saver to the RZ and also 2 M2.5 pan head mounting screws. The price is $7.00 for either version shipped via first class mail. Paypal preferred to--Jblk9695@verizonmail.com
or email for my address if you want to send a postal money order.
I also have end bells if you prefer to replace the stock one for $10.00. These have a thicker end flange and come with longer M2.5 mounting screws for better thread engagement, less chance of stripping the hole.
Email or PM for photo's.

Thanks for posting the link Jon.
Thanks Jonathan.

[Earthbound]

What a fine idea. Gotta have one of the GWS sized savers. Paypal in its way.

[birdie_in_texas]

what do you do if one of the the screw holes on my 300 is already stripped out..?

[jperch]

Birdie,

I think you just get one of his end bells.

Joe

[birdie_in_texas]

i kind of jammed in a little bigger screw and it seems to be ok, but his stuff is WAY pretty,,,!

What screw hole is stripped? This plate attackes to the motor using the 3 gearbox holes on the endbell. You attach your gearbox to the 2 holes on the plate, so it doesn't matter if your gearbox holes are stripped on your endbell.

John

[birdie_in_texas]

yep..i stripped one on the front while putting it into yet another new gws gearbox, because i killed the other...

i put a screw in it thta is just a little bigger..i think it is standard and not metric..so i fi had your deal, i could just pooky it in with thread locker, and then when i transfer, i would be messing with the screws on the endbell adapter thingy..right?

[Jblk9695]

Holy cow, how many Razors do you have in the plane in your avatar?:D :D
Correct, you just attach the Razor Saver to the front of your Razor with 3 flathead screws, see the photo at the beginning of this thread.

[birdie_in_texas]

ha! it would definately take a few razors for the edge in the pic..! hahaha might be kind of fun!

it is only 28% Edge 540..will be powered by a little ole Brison 3.2..and only about 16# (hopefully) if i can ever get it put together!

thanks for the info!

birdie:)

[Quags]

Hope these are still available, just sent Paypal for a couple. Great idea.

[Jblk9695]

Quags, thanks for the order and I'm in the garage(backyard machine shop) making up a bunch.

[David Hogue]

Jerry,

sent paypal for one... I havent stripped mine, but I dont like the way the endbell is drilled and tapped:D

Thanks,
David

[Jblk9695]

Thanks Dave, sent you an email for which type.

Jerry

[Jblk9695]

Hi-- Now that we have 2 sizes of Razor Savers, please specify which one you would like when placing an order. Just note RS for the one that fits the Razor motor diameter and RS300 for the one that fits the GWS gearbox. Thanks

Jerry

[David Hogue]

Jerry,

I didnt get the email, but the razor dia will work fine for me

Thanks,

[Dennis Everett]

Jerry,nice looking stuff,what are they made of?looks like ss,have you ever thought of makeing a adapter simular to this to fit a himax motor to the gws gearbox?the ones they have now called cnc apapter plates are so thin with just a few threads in alum that im afraid mine will strip out,even tho i havent heard of this happening,i see your close by,give me a call(# in phone book) if you think this might be another piece you want to make,.......Dennis

[Jblk9695]

Dennis, these are made from 2024 aluminum and all done with armstrong power. I will give you a call about the other adapter plates, I am always looking for other projects.

Jerry

[KsFlyer]

I need three with the flanges for the GWS 300 gearbox. Is this the RS300?

Please advise so I can paypal you.

Thanks,
Troy

[Jblk9695]

Hi Troy, yes the RS300 is for the GWS.
Thanks
Jerry

[Tram]

Are you still making these? ;)

[tabbytabb]

Just sent paypal, I cant believe you can make and ship these for 7 bucks :)

That is awesome, Since you are obviously very skilled at machining wanna make me and endbell for a cdrom motor??

:) JK, but thanks for the razor saver!

Tabb

[Jblk9695]

Tram, you bet, keeps me out of the wifes hair.
Tabb, sure, just let me know the dimensions, and thanks for the order.

Jerry

[thechosen1one]

Jerry, I think you have a new profession. I could use some new bells for CDRom motors also. Will have to get specs and get with you on pricing
Andy

[tabbytabb]

Yeah, I seriously think you would sell a ton of them if you manufactured some bells for generic size stators. This is the only piece that I need to complete my cdrom motor for my shockflyer and I dont have the tools or ability to make it myself

Tabb

[CactusJackSlade]

Jerry,

Just got your parts in the mail - one end bell and two Razor Savers for the GWS gearbox...

Maybe someone has suggested it already, but what about a new end bell with a large outer flange to fit the GWS gear box? Kill two birds with one stone?

By the way... what is a SAFE way to press the old stock end bell out?

Thanks for a nice product, I'd highly recommend them!

CJS :)

[KsFlyer]

Here is some info on making alum end bells. You need a ferrous ring in them.

http://www.rcgroups.com/forums/showthread.php?s=&threadid=157413&highlight=ferrous

Troy

[Jblk9695]

CJS-Soak just the end of the motor in lacquer thinner to loosen the bond and then rotate the end bell by using needle nose pliers in the vent holes, don't push them in to far or you can damage the windings, once the end bell rotates then you can pull it out. If you try and press the end bell out with the shaft you take a chance of doing damage to the bearings. Make sure to just soak the end in the thinner or you might remove some of the coating on the windings, also when re-assembling make sure to oil the bearing. You can use some CyA or Loctite to bond the new end bell in place.
I can do the end bell with the bigger flange if you would like, just let me know.
Jerry

[Jblk9695]

Troy, I think my brain hurts, that was a lot of information about motors and magnetics. I think I will just do the machining and let you people figure out the flux capacitors, Ha Ha.

Jerry

[bigbike44]

Jerry,

Received my set today(thanks for the quick ship). Nice job! If you think about stopping production, you better let us know so we can stock up.

Thanks
Steve

[Jblk9695]

Thanks Steve, I'm working on more right now.

Jerry

[Earthbound]

Got mine in the mail today. Very nice work.

[Jblk9695]

Thanks Earthbound.

Jerry

[Park_IT]

These look really nice. I sent PayPal for one each of the Razor Savers.

Bryan

[Jblk9695]

Thanks Bryan, there on the way.

[Jblk9695]

Just to let everybody know, I make these as needed. When my stock on hand gets low, it's off to the lathe and mill to make more. So don't worry about the supply running out.
And thanks to everybody for your kind comments and for your support, I really appreciate it.

Jerry

[Park_IT]

I just have to chime in and say that these are very nice pieces of hardware (the shipping was really fast too). The fit and finish of both styles of Razor Savers are superb.

Excellent! Thanks again.

[David Hogue]

got mine and installed....fit and finish is great, and now I dont have to worry about stripping the razor!

Thanks Jerry,
David

[easy2fly]

llet us know if you will be putting anything together for the himaxx motors. Thanks ,jeff

[Larry3215]

Cool idea. Any other motors you have plans for? Mega? Himax?

Larry

[Jblk9695]

Yes, any that I can get my hands on to measure. I'll post others as soon as they are available.

Jerry

[birdie_in_texas]

a stick-mount version of the WON gearbox would be nice too..especially if it was cheaper!

[Dennis Everett]

Jerry,i got mine,great looking stuff!!This is Dennis we talked on the phone a while ago,i have a himax if you want to measure it,I also have a few other ideas of stuff you could possibly make.........Dennis.....ps i think your prices are too cheap...did i say that out loud?.........

[Jblk9695]

Ok, from know on everything is 3x's as much, Ha Ha, just kidding. Dennis, I would like to measure the Himax and hear your other ideas, send me a PM with a good time to get together.

Jerry

[Earthbound]

I would love to have a mount for the MPJet 25/35 and 25/25 motors to fit a GWS gearbox. I will see if I can put together the measurements you need.

[Jblk9695]

Earthbound, that would be great.

This is the hole layout and other dimensions for the MPJet 25/35-20 original and Mk2 versions.

http://home.earthlink.net/~jettas4me/images/MPJET.JPG

[Jblk9695]

Earthbound, excellent. So what is required is a plate like the Razor Saver but to fit over the hub and match the 3 mounting holes and also have the mounting holes for the GWS gearbox, etc. Are there any cooling (vent) holes in the endbell of these motors? And if so what is the diameter (bolt circle) they are on? Thanks for the info.
Jerry

[Earthbound]

There are no cooling holes in the front (or anywhere for that matter). Needs three holes for the 2mm screws and a large hole to clear the hub.

Also, it needs to fit the EPS400C gearbox frame, not the EPS300C. That is because the motor shaft is 3mm. There is not enough meat in the 300C pinions to drill out to 3mm. Need to use the 400C pinions (2.3mm) which are larger and can be drilled/reamed to 3mm. Do you know the EPS400C mounting dimensions? If not, I can find them. They are probably on the GWS website, and seems like I remember seeing them on the back of the EPS400C blister packaging as well.

[Jblk9695]

Earthbound, sent you a PM.

[Jblk9695]

Chuck in Alaska, I'm having trouble sending you an email and I need to know which type of Razor Saver you want.
Jerry

[dulcelife]

I am ready to order either the endbell or the saver.

Has anyone done the endbell replacement? I need to know how it went and if there were any problems. Hate to be the first.

I would go with the saver but since this will go on a 350 for a Piccolo I would like to avoid the extra weight of the saver mounted onto the stock end bell.

What is the weight of the endbell versus the saver with it's three mounting screws?

Thanks

Luis~

[Jblk9695]

Luis, I'll weigh the Saver and endbell tomorrow and post it here, I don't think there is very much difference.

Jerry

[Jblk9695]

Weight of Razor Savers---
RS(same diameter as Razor)=1/16 oz, 1.78 grams
RS300(GWS gearbox)=.075 oz, 2.13 grams
Endbell(with thicker flange)=1/8 oz, 3.54 grams

I would think that an RS on the stock endbell would be about the same weight as the endbell I make with the thicker flange, maybe a little more but only by fractions of a gram.
Jerry

[dulcelife]

Thanks for the information. The weight is insignificant in light of the razor's power improvement over stock engines.

I just sent payment for the Saver.

Thanks

Luis~

[reefer]

Jerry,
How could I miss this post.
Would you quote me one RS with Shipping cost to hong Kong by PM or here?
Thanks for great solution for such a small motor.

[Jblk9695]

Reefer, airmail letter post would be .80 cents for an ounce, so add .50 cents total if you order one to three Razor Savers. Please let me know which style you need-- RS to fit the diameter of the Razor motor or RS300 to fit the GWS gearbox. You can use my email for paypal-
Jblk9695@verizonmail.com

Thanks
Jerry

[reefer]

Jerry,
Funds sent, plz, check your paypal account.
I need one RS version.
Thanks.

[birdie_in_texas]

hey jerry..do you remember when you mailed mine by chance?

i am getting paranoid that the post office lost the things...


thanks,

birdie

[Jblk9695]

Reefer-Thanks for your payment.
Birdie-Well, Texas is kinda big and the post office probably got lost. Actually I sent them out on the 5th so keep me posted as to when they arrive.

Jerry

[birdie_in_texas]

cool..thanks Jerry..!

[birdie_in_texas]

man...these things are awesome!! i am getting Jerry to get me an endbell version for my new 300...

Let me know how much Jerry!


thanks man!

birdie:)

[Jblk9695]

birdie, glad you like them. I can make an endbell version that will fit inside the GWS gearbox for
$10.00, just paypal and specifiy RS300 endbell.

Jerry

[SlowRider]

Jerry,

I think it's great that guys like you and Won are crafting such quality product. I just sent you a PayPal for one RS and one RS300.

Thanks,

Andy

[Jblk9695]

Thanks for the order and kind words.

Jerry

[birdie_in_texas]

ok Jerry..you should have some $$ for the endbell one..

thanks!

birdie:)

[dulcelife]

My Razor 350 had been saved!

Thanks Jblk9695

Amazing little piece of work and some new mounting screws to boot.

Great service.

Glad you like it, thanks for the kind words.

Jerry

[lagcisco]

hey this looks like what I need, but im not sure, this is what happened, I bought the Razor 2500A (old version where the gearbox is epoxied on) and I crashed it and broke the gearbox off and I ended up losing one of the tiny gears I was going to send it in for repairs but havent got around to it, so will this fit on my motor? i'd like to use it on a gws gearbox or some other gearbox, anyways the face of the motor (black anodized aluminim i think) was machined so that the gearbox could be epoxied on so now the screws barely hold into the motor, will this motor saver work for me? also i think the prop shaft is shorter than a regular razor 2500 from looking at the pics so I dont know if mounting the saver would reduce the prop shaft even further wished i had a camera to take a picture of this so you guys could see.

[Jblk9695]

lagcisco, I havn't seen a 2500A up close and personnel so not sure. The Razor Saver is 1/8" of an inch thick so the shaft length will be reduced. If the 2500A has the 3 small threaded holes then you can attach the Razor Saver to the endbell. Take some measurements and see if you will have enough shaft length to mount the pinion. If you decide to get a Razor Saver, please let me know which style, RS to fit the diameter of the Razor motor or RS300 to fit the GWS gearbox. Hope this helped.
Jerry

[lagcisco]

the shaft is really short,i'd say maybe like 1/2inch.. its tiny, ill measure it later tonight, and as far as the 3 holes, well since they were machined out the screws dont hold onto the thread, so theres no way to mount the saver i guess, razormotors doesnt even have phone number on the site, theres an address on there but i dont want to send it in and not get it back, i'd still like to use the motor for something, oh well

[lagcisco]

hmm i just saw some endbells on here:
http://www.rcgroups.com/forums/showthread.php?s=&threadid=178807&perpage=15&pagenumber=5
looks like thats what i need instead of the motor saver.. do i need any special tools to remove my endbell and to install that new one?

[Jblk9695]

Lagcisco-Soak just the end of the motor in lacquer thinner to loosen the bond and then rotate the end bell by using needle nose pliers in the vent holes, don't push them in to far or you can damage the windings, once the end bell rotates then you can pull it out. If you try and press the end bell out with the shaft you take a chance of doing damage to the bearings. Make sure to just soak the end in the thinner or you might remove some of the coating on the windings, also when re-assembling make sure to oil the bearing. You can use some CyA or Loctite to bond the new end bell in place.
Just be very careful and proceed with caution so as not to damage your Razor.

Jerry

[lagcisco]

ok well i want to get one of these endbells for my razor 2500, do you have any already made or is there a waiting time?

do you have endbells made that will fit with the GWS 350C gearboxes?

[Jblk9695]

Lagcisco, is the GWS 350 the same size as the 300? if so then yes I have endbells that fit into the gearbox. The price is $10.00 shipped with 2 M2.5 mounting screws. Just send payment via my email address to paypal:
Jblk9695@verizonmail.com

Jerry

[lagcisco]

hmm im not sure if the 350 and 300 are the same size.. anyone else know if they are?

[Jblk9695]

If I can remember, I'll try and find out tomorrow at the Mid Winter Electric meet in San Diego.

Jerry

[lagcisco]

mid winter electric meet in san diego.. hmm that sounds like fun, i live in los angeles, where is this taking place?

is it an event at some convention center or at a flying field? going to do some searches to find out where its at.

[lagcisco]

ok found out where its happening, that was easy: http://www.sefsd.org/

i might just go tomorrow!

[Jblk9695]

Look for the old F__T with the gray beard and a name tag with Razor Saver Man on it. That will be me.

Jerry

[dulcelife]

Sending payment for an Endbell for my Razor 350. Unfortunately the motor shaft is not long enough with the saver mounted in my Piccolo application.

Boy do I regret having bought this motor which turned out to be stripped.

Darn.

The GWS EPS300C and EPS350C gearboxes are identical. The only difference between them is inside the can motor itself.

[lagcisco]

thanks for the info earthbound, I just sent jerry the payment for the endbell, hope everything works out ok with the short shaft and all

[Jblk9695]

Earthbound, I haven't forgot about the adapter for the MPJet, just been busy. Also need to get some M2.5 flatheads for the gearbox mounting screws. I trimmed one of the adapters I have and it looks as though it will work ok.
Jerry

[Earthbound]

No worries, Jerry. It is not urgent. I've been busy Razor hunting, and caught two more of the little rascals!

[Jblk9695]

Well, then you will need two Razor Savers!

Jerry

[thor4944]

Ok...I am confused...will this prevent my black Threads on my gearbox from getting stripped....someone told me to put an "O" ring on my razor motor to prevent that.......is that what this razor savers are???

[Jblk9695]

thor, The Razor Savers are if you strip the mounting holes in your Razor motor, you attach the Razor Saver with 3 flatheads into the M2 threaded holes on the endbell and you have 2 new M2.5 mounting holes. I have a Razor Saver that fits inside the GWS300-350 gearbox which eliminates the slop. Go to the start of this thread for photo's.

Jerry

[Sonic1]

Jerry,

Do you know if the RS300 will allow you to bolt a Razor motor into an EDF75?

Thanks,
Jeff.

[birdie_in_texas]

anxiously awaiting my endbell razor saver! the regular razor savers are awesome!

[Jblk9695]

Jeff, I don't know, do you have some dimensions or perhaps a photo of the installation? I can tell you that the diameter of the RS300 Saver is .955" to fit into the GWS gearbox and the RS saver is the same diameter as the Razor motor. If you need another diameter, let me know.
Birdie, should show up anytime.

Jerry
