I am going to eventually convert this mill to CNC but for right now all I really want is a power feed since I normally operate this one manually.

I bought this mill in 2006. I have put 20 thread per inch leadscrews in it and changed the spring for that air spring assembly.

One day if and when the motor dies I will probably adapt a spindle motor and a VFD to it with a belt drive But that's a project for a later day...

So far I have bought all the parts for the powerfeed except the plate to use for the stepper motor adaptor.

I was looking over the internet for a reasonably priced CNC conversion kit and at $615 with no steppers lost me, however since I have a lathe and mill I have what I need to make the same parts.

I am a bit more budget minded and I do want be able to use this mill manually so I will retain those fairly fresh leadscrews.

The most expensive part of the powerfeed controller... Believe it or not it is the aluminum chassis. Yes a plain jane metal box. I bought the cheapest one that would hold all the parts.

The large parts inside were ready made, the 12 volt switching power supply and the 3.5 amp bipolar driver.

The square wave generator and the 12 volt to 5 volt regulator were DIY kits. The Square wave generator was modified for this application. You can build that square wave generator yourself at Radio Shack but it will cost 3 times the $2 I spent on the kit with an already etched circuit board. While the square wave...Continue Reading

I just got this built up and have done the 5 Volt test and then added the driver chips as per documentation

Test voltage is 5.03 Volts.

This makes the 4th controller I have built and I have not had any failures either from the build or from use. This is an excellent product and I could not recommend it any higher...

I have yet to test it's final function but if it's like the last 3 I have no fear that it will work when it get added to the controller chassis.(A retired CD Duplicator case.)

Getting back to my CNC mill project as I was so rudely interrupted by medical issues an weather bad enough to keep me indoors. I am on 2 meds that leave me temperature sensitive.

I noted a light surface rust on my slides so I took them to the bead blaster for a cleaning, masking, a spray of Rustoleum and a light coat of oil.

I have part of the upper section cut for the legs, I need to finish that up then I can set the Y and Z axis in place and wire it up.

My spindle motor is in, I just need to wire it up to the speed control.

I have the Stepper controller and power supply as well as the USB interface.

I need to install my video card for Mach 3 compatibility and hook all the jumpers and switches. I violated convention(Mine anyway.) and used a switching power supply to run the steppers and controller. I think in a week I should have it all up and running and create a program to drill the table for holding the plate to the frame and holes for clamps.

Soon as this is done I have about the same amount of work to do to my 4 axis foam cutter.

My new antique Green Instruments pantograph/engraver just arrived from Chicago.

Lots of stuff you can do with this. From labeling to use as a mini router-copier.

Someone sent me a picture of me from 1979...

This is me with a wing from a Goldberg Senior Falcon that I bought after a crash, I had just recovered the wing. This picture was taken in my 3rd year of the Navy at the Yokosuka Naval Base in Japan.

I have not gotten back in to kitting for lack of work space...

I was thinking of adding a workshop in the back yard but I got to taling about the sale price of my place here when I sell it and "out buildings" are not even looked at when appraised. Made me think. (that hurts)....

So I talk to a few guys I know and figure that a house can be had in good shape for as little as $10,000. With that in mind I think I want to buy 5 houses. 4 to rent and 1 for a shop.

I am retooling some CNC stuff and building a couple of new CNC tools so I need the room.

So I am hoping to get things done by Christmas.

I hate to profit from the misfortune of others but this is a chance to get in and make a few buks on the rent and a few thousand when the market comes back

Well I managed to fall down the stairs last week, ankle tweaked (again ) and elbow still hurting, just getting where I can stand again. darn ankle is still swollen... socks dont fit yet...

It's 11:00 on saturday night and I am cutting foam, got me a barstool (my lofty perch) so I can see the machine without the constant standing.

We are sending out the 2007 version of the Sickle 480/M it uses the MAXAMPS 3s4000 mah lipos

I got 4mm coro!

I am low and out of some 2mm colors.

We will be ordering Monday, where I get it the online store is jacked up and wants to hit me $130 shipping for one sheet. I will call and get that fixed tomorrow.

I bought out my carbon suppliers stock, anymore when I place an order I have to email ahead and make sure my suppliers have enough stock for an order, if not I just take what they have. this is a different feeling for me, I never had that happen til this summer. I feels good but is becoming a pain. I am now lining up more than one supplier for items that I have to buy. This is uncharted territory. I am beginning to see the appeal of this business.

Monday I will be all caught up. Time to cut ahead of the game for Christmas. Build up the stock.
