Turns out there was a missing e-clip. I was able to snag one from the handle. I don’t have the pulley yet so I took a dead motor from my pile and made it a sacrifice. Since it didn’t run at all before not much is lost IMG_4287.jpeg Obviously not awesome, but if it runs at all that would be great. I ...

Hopefully this one doesn’t walk away on its own

Thanks for the tip. Looks like that wasn't it.
I just noted that the high current draw doesn't happen until the blue motor lead is connected to the motor.

You caught my attention. Can you tell me any more? I don't know of Dave Geitner , has he used and compared anodized samples? I've ordered a couple of Caswell's dyes and so far haven't had any headway. Almost tried gold n. I did look at there example of gold s, it appeared too bright and too yellow....

This will take a bit of work to get going the lathe works well in the axis along the motor. However the mechanism that is supposed to hold the cutter against the com does not seem to hold it's position properly .

That didn’t work. There is a short… somewhere. The bec is working and powering a receiver. But my power supply is pulling 3 amps. The motor is getting 0 amps or voltage. I think I am going to pull all the parts off and try again. If I am thinking about this correctly. I can pull all of the fets off ...

Usually a diode tester will be low enough voltage not to damage FET's. The tube they shipped in is esd proof, there might be a little lightning bolt symbol on it if you look carefully. Silver solder will probably work fine if it looks like regular solder it's probably very low percentage. High perc...

I bought this comm lathe off ebay https://www.ebay.com/itm/285846016683 Screenshot 2024-05-16 at 11.21.57 AM.png I don't know much about it but it looks like a stock motor lathe. Does anyone know the model, or have a link to instructions on this lathe or type of lathe? Is there a piece missing that ...

I haven't popped into this thread for quite a while. Sounds like you're handling things just fine. In general, devices in that package don't sit flush to the PCB, that is a unique construction for our hobby to make the footprint small and help ruggedize the assembly. So that wider lead makes sense,...

It looks like Caswell may have a kit that would help.

I am not sure if this is just a degreaser, aluminum black and, a sealer.

The proper color dye for a Cadillac gold pan is Caswell Gold S

Thanks to Dave Geitner for the information.

It didn't seem like there was a great deal of interest in the kit here for the asking price. It seemed to be pretty run of the mill except for the factory gold truck nose plate.

You could also remove one of the other FETs and use it as a guide to trim the leads on the replacement. Make them a close match and put them back on the board to verify that the tops of the built in heatsinks are even. The trick to soldering is to get the lead and the trace on the PCB ho enough to ...

My first attempt using a knife to shave the pin didn’t work IMG_4272.jpeg I used an Emory board to file down the legs and they fit easily IMG_4273.jpeg Folded over the leads. Did the ground plane pins facing the wrong way. Some of the pins looked as if they would cause trouble, so I trimmed them a b...
