Made a sander out of a treadmill based on others found on youtube.

Found a Weslo treadmill on Craigslist for $20, pulled off the drive belt and walking belt. Ordered a new drive belt for $12 shipped and an 80 grit sanding belt for $28 shipped.

Parts came in 4 days and I put it together for a test tonight.

Howsthewind has a mondo belt sander made by Grizzly, and advised me it uses an 80 grit belt. I'll have to see if I can get a belt with 80 on the left side and 100 grit on the right side.

Belt is 13 inches wide and 42 inches long tho when you order you specify the running length.

Warning Turn down the sound. I had the vacuum running to collect the dust.

Update12-26-14: painted the first paid of servo covers for my moth. Also building another mold set for servos the stick out a bit for my gulp sr-t. See pictures in post below.

Someone asked my about the sand epoxy mix. I just mix up epoxy in a little paper cup, then add sand until its a little like ketchup. It takes 3 or 4 batches to fill up the mold. Might be helpful if the last layer is not so thick so it will self level more but I have not tried. Also the last mold I made I did in one shot, mixing and filling till the mold was full. I was worried about the epoxy/sand getting hot but no issues. The garage temps were in the 60's.

Update: I tried vacumme bagging the FG and had some issues so I made a male mold of the servo cover using Sean Porters techniques.

See post below for pictures.

Update 12-18-14

The servo cover made using a mold form worked. See new post 12-19-14.


Original post:

OK my first attempt at making a mold.

Watched videos, read threads and talked to Kevin to figure out what to do.

Figured a servo cover is about as simple as it gets.

Carved a nice servo cover shape out of some wood stock and glued it onto a 1/4 inch thick board.

Put 6 coats of wax on the plug and top of the board.

Mixed epoxy, cab, and graphite and painted on the first tooling layer.

Waited an hour and when tacky enough that a brush stroke does not disturb the surface, pained another tooling layer.

When the last layer was tacky,...Continue Reading

Sunny 70's at the beach, 60's in the water, fun nuggets. Can't beat November in San Diego.

Day after Thanksgiving. 70's again, 60's again, 2-3 ft with 4+ sets as the tide started to drop. No wind, clear water, sunny skies. What a way to spend the day away from all the shopping craze.

I am remodeling an old CR Blazer. First task was to remove the wing and tail, remove the control surfaces and strip the old covering.

Removing the Monokote is a pain in the butt. The plastic film would come off but not all the pigment/glue. I tried sanding but the sandpaper gummed up.

I read about applying tape to the residue, applying heat and stripping the tape off taking the pigment/paint.

So I tried it and it works. Pictures show the process. Don't know what I'll do with the tiny amount left over. I might just sand every thing smooth and recover. Or try lacquer thinner.

OK so I'm officially retired and decided to build another Steve Drake EPP Glider (http://www.stevedrake.com/).

This is an old 2002 kit of the Gulp DS. There is a later Gulp DS II, but this one is the original. From the website the changes from the DS to the DSII is a longer (2 inches) and narrower fuse. The Vert tail and wing is the same.

I bought this kit a few years back after building a heavy JW60 DS Special (4 spar wings) (110 oz) and wanted something to fly in lighter winds 10-20 mph. http://www.rcgroups.com/forums/showp...&postcount=540

Just for reference the kit includes:

1. Instructions
2. EPP Fuse. Fully formed, no sanding needed. Very convenient and very clean.
3. EPP wings in their beds with carbon spar channels cut top and bottom. Similar to the JW60 DS Special.
4. EPP Vert Tail in their beds. Cut in a nice Airfoil shape.
5. TE Subspar wood.
6. Aileron Stock (1.5 inch).
7. 4 Carbon spars.

Basic instructions:

1. 5 min epoxy the wings together
2. Cut access hole in center of wing where spars come together for later wrapping with carbon weave and tow. Some manufactuers provide a metal joiner tube for the spars to slide into in the center of the wing, but Steve's designs have you wrap the spar ends together with carbon and epoxy to join them.
3. Goop the spars in.
4. FG the wing joint in the center
5. Glue on the TE with 5 min Epoxy
6. install servos.
7. Stapping tape and Cover wings, cover ailerons and tail.

Completed a Steve Drake Gulp SR-T 48 inch wingspan EPP Sloper. T stands for travel version which means the wings plug in. Maiden was Wednesday July 16 at Dave's beach in perfect 10 mph winds with the CG at 2.54 inches per instructions which unfortunately was too far aft. Three flights was needed to get the plane flyable adding weight and reducing the elevator throws each time.

With the weight buried plus 1/2 oz taped to the nose for fine tuning and the Gulp flew again at Dave's in 10-12 slight north winds. This time was much better. 1/4 oz was removed and the plane flew better. It's close and a few more flights will dial it in. I'm thinking the last 1/4 is not needed but the wind dropped before I could test fly again. As it is now it flies nicely.

AUW is 23 oz. with the cg moved up to 2 1/4 inch, once the cg is dialed in I'll add the ballast fitting. Should be a great Sloper tho rarely seen.

Construction was per plans except for no strapping tape, instead I used parkligjt ultracote and 5 mil new stuff on the wings. A carbon rod pin was added to the trailing edge spar for alignment. The tail is the same except for 3 mil NS. The fuse was taped once with fiberglass tape then gooped aka moth.

Gonna have to build a box for it next.

Kevin and I made a road trip to Parker to DS over the 4th of July weekend.

We build wings with LEDs for some night flying, Kevin built a 60 inch Queen Bee and I built a 48 inch Bee Evo. Both has LED strips, Kevin's was lit up with 12 V and I used a 9 V battery. In hind sight the 12V was better since the LEDs I had dimmed quite a bit after only 10-15 minutes of use.

Another reason to fly Parker was to give Kevin's Carbon Kato Mod a chance to DS big air. At 88 oz with a double carbon bagged 72 inch wingspan this wing is big and strong.

Plus I needed a DS fix.

We arrived at Acton before 11 and the main drag south from the 14 was closed due to their 4th of July Parade but we detoured around and got up the hill before noon. Wind was 18-21 mph from the west and as we were setting up camp the wind started clocking to the north, then to the east, south and back west. Whiskey Tomato Fudge, Took about 3 hours.

In the mean time a quad passed by going up the hill, then the kid and his girlfriend came walking down sans quad. Well they flipped over while climbing the hill and broke the quad and the kid has a nice road rash, luckily the girl was not hurt. We offered them a beer (too young), shade and tried to clean up the wounds. Soon a couple of locals showed up to help retrieve the quad and walk the kids back down the hill. So that helped pass the time.

Soon after a couple guys from LA area showed up with a go pro on a quad, Destiny and a Reaper (6ft plank).

Years ago I got a 60 inch LEG-39 with a simple silver solartex paint scheme with US Army markings.

It acquired a number of creases and rashes from flying at Dave's Beach, Fermin and Cajon Pass. Daves has a gravel and decomposing asphalt LZ, Fermin is a brush covered hill, Cajon is scrub brush and rocks.

Decided to redo the old bird with a new paint job after sticking solar tex over the cracks and scratches.

Used Krylon Grey under sides, Krylon Olive Drab and Krylon White with some unknown red for the spinner finished with Major Decals.

Delayed Still: Sorry for the delay. Will start back in 2015. Have a new belt sander to help shape the wings.

Note: Work is being delayed on this wing build due to Little James - James and Rosarios new baby.

This will be a slow going thread on making wings for a couple of Opus V fuses. Summer of 2013 I bought a 2M Carbon Blade fuse, 2 Opus V fuses and a T Tail fuse with a missing nose.

The 2M Blade fuse was fitted to my busted up Blade wings and is currently flying again.

Jame D and I will be making wings for the OPi. We started by blocking out blue foam, creating templates and cutting the middle section.

Plan is to cut the outer wing panels then building the wings PSS like. Which means Balsa or Ply wing Sheeting, a 3/4 inch popular or bass wood LE and a 2 inch Aileron Stock TE. We then plan on bagging the wing with carbon and 2 layers of 4 Oz glass. Kevlar live hinges too.

Here is my Savaron S. It's modeled after Charlie Richardson's Savaron wingeron. But mine is a FG Turbo fuse, Ward's pitcheron bling and turbo cores.

This is a sorta build log: http://www.rcgroups.com/forums/showthread.php?t=1327243

Main differences is the fuse is slightly shorter than the Savaron. The Savaron is a wingeron with a bellcrank mechanism for the cruciform elevator. I made mine simple with a pitcheron set up.

Brian Cortice scratched built two true Savarons which got me thinking about building this plane.

Here is a video of a recent flight in light winds and a post flight photo.

I'm finishing up a busted up 2M Carbon Blade. First off a bit of history. 2 years ago John Kim busted up his 2M Carbon Blade DSing, he gave it to me in a plastic bag. Fuse broke at the base of the slipon nose cone, broke clean behind the Saddle and again in front of the Vtail saddle. The wing saddle was cracked on both sides from the crash. The wing was busted right where the aileron and flap control surface meet, both drag spar and main spar was broke.

Broken Blade (2 min 26 sec)


So I fixed it all, did not paint it, but left all the repairs exposed, installed a spectrum carbon receiver, new 85MGs and a life battery and flew it for the summer, couple of frontside tuning flights then a few Bill Hill DS sessions and 2 Parker DS sessions. No vids of the DS flight but here is the front side maiden.

Last weekend Kevin, his Bro Mike, their buddy Bill, my son and I went out by the Gypsum mine south of Ocotillo OHV to celebrate our freedom to shoot before the oppression begins. At the end of the day we pulled out out target plane and shot at it with my son's M4 Airsoft.

Kevin flew in the vid.

Kevin donated the plane 3 servos, motor and lipo, I threw in a servo, ESC and some labor. The plane flies great and took hits on the bottom and tail. Lots of fun and the plane is ready for the next desert outing.

I built a Drop Arm Gravity Foam Cutter from an old issue of RC Soaring Digest.

http://www.rcsoaringdigest.com/pdfs/...SD-2008-11.pdf

all kudos goes to Curtis Suter, the author of the how to article, thanks for sharing your knowledge.

The instructions are very good and easy to follow. Explaination of the Drop arm pully setting for a tapered wing is very good too as well as now to test the setting before you cut foam. You can make a cheaper setup but this design looks to be durable.

I'm no expert so I cant debate one design over another, wire size, power supplies or defects. I've only played with EPS from from Home Depot with swing wire templates so far. But I'll post what I did and how it works.

Tips

http://www.rcgroups.com/forums/showt...ds#post2741007

Photos are of the Cutter I made using the plans.

I deviated from the plans in these ways:

1. Suspended the bow vice using a wheel. The bow is suspended at the Bow Center line.

2. I replaced three of the pully wheels with eyelets. This keeps the pull string in place better than the pullies.

I tried using the power wires to the bow as pull strings but the wire I have is too stiff. Might try again if I can find very flexible 18-20 ga wire.

The templates must be very smooth. I sanded the edges with 220, 400 might be better.

Things I learned.

I picked up a broken Destiny from another RCG Sloper.

http://www.rcgroups.com/forums/showt...hlight=destini

It has a broken Right Wing Tip with delaminations on the aileron, top and bottom wing skins and a few other issues. The Left wing was perfect. The V-Tail portion of the fuse was repaired by the previous owner. Servos in the wing and two in the fuse and receiver battery.

I replaced the battery with a LIFE and both fuse servos with HS-81MGs. Installed a 7 ch Optima Hitec 2.4 receiver.

Fixed the wing and had to add lead to the other wing to balance.

AUW is 28 oz RTF. May lose some weight once I get the CG right.

Remaiden-ed the Destiny Monday Oct 8th at Daves Beach in 10-12 mph straight in. Flew fine but needs less nose weight. DSed it later in the day at Bill Hill with video. This is a long video so be warned. I did not have the time or desire to edit it much.

Destiny DS BH 10-8-12 Raw Video Long (26 min 50 sec)


Issues

Right wing has a very small amount of warp to fix.
CG is still too fat and nose heavy. CG on this flight was 60 mm.
VTail incidence is off. Have to shim the LE of the V tail up some amount.

Maidened by new to me Fred Sage Addiction at Torrey Pines Gliderport this evening. Purchased from another RCG member ARF. Had to retape the rudder and one aileron hinge, re-set a couple servos, install a Spectrum 7100 with satellite, a pair of A123 cells I had laying around and program my JR. CG was about 5 inches from LE with 1 oz of lead.

AUW for this flight was 57 oz. Wing area is 950 in^2 (6.6 ft^) so the wing loading is light at 8.64 oz/ft^2. Compared to my Espada R with a wingloading of 9.55 oz/ft^2

Wing chord is wide with a WS of 118 inches/3M carbon bagged wings, bare fg rudder and full flying elevator. Rudder seems huge. FG fuse with slip on nose cone. There is a hook for launching and this "Skeg" under the nose for landing.

Wind was a bit south and light, one or two Paragliders were scratching to stay up.

Plane flew great, seemed to respond well to camber and rudder turns. Elevator is close, maybe a bit more to get ludicrist loops. Very stable and easy to fly. Slows down nicely for landing, in fact the first landing was a hand catch.

I've heard this plane was a "landing machine" and I agree.

Three changes:

1. Remove some nose weight. At least 1/2 or all of it. Time will tell.
2. Increase Aileron Throws by 50%.
3. Maybe add a ballast tube.

Looks like a plane I'll keep since its one of the last great bagged wing TD planes and its got history with Torrey Pines Gliderport and the Torrey Pines...Continue Reading

I finally got some video of my repaired D-60 (purchased from the man himself Joe Manor).

This plane just loves to DS.

HD Keychain video on a hat. No one else there to radar. Looks about 150 mph.

Landing was a bit interesting ----- Crow had one aileron going up more than the other so it wanted to roll.
