thanks! the nice thing is that the transistor/op amp seems to be a 90% match and those are a standard diameter. helps to find the washers
 
Does anyone explain in this thread the proper way to disassemble an OpAmp, for adding threaded rod? Or is it just, chuck it up in the lathe and drill it out and hope for the best?
 
I just got a pair of OpAmps from thd9791. There doesnt seem to be anything to do as far as disassembling them. I was planning to do the same thing I did with my old transistors. Rip off the leads and then drill out the backs. Then I'll glue in a small socket head cap screw.
 
The trick to drilling them out was to create a wood “clamp” to hold them so you don’t scratch or dent them in a vice on your drill press. The jig was a hole drilled into wood, with a slot cut to the edge of the wood. Some of the filler in the amp ops is very hard to drill.

I’m looking for a photo of James’ jig.
 
On the transistors Teecrooz sent me I just grabbed a nail, dug out a hole (holding the transistor in my fingers), then used a dremel to take the head off a tiny bolt. glued it into the hole. doners!

We are talking about transistors right? I'm sort of just dropping in and out of these threads lately!
 
Word, I can totally whip up a wooden jig like you described.

And you ain't kidding about being tough to drill! I probably dulled the center drill I was using in the tailstock drill chuck last night! I reckon it's some sort of ceramic in the center underside.

It may be easier to remove the lathe from the equation, rig up the wooden clamp, put that in the bench vise and go to town with a diamond or stone burr in the Dremel.

That's why I found putting the tranistor on a protective rubber surface and then just HAMMERING a nail into the underside cracked through the "Ceramic" (whatever it is) and then just twist and rotate the nail around til it digs out a good hole.

You can make them with a V cut into the ends too which would give you good purchase.
 
I sort of did what NeoRutty did... took a dremel and drilled a hole, cut the head off a brass screw, epoxy and voila.

Though when I do the swap out for the Op Amp cans, I was going to try the wire twist and use a small wire cap and see if that would work...
 
Thanks for everyone's help!

Here's where I'm at... the one with the dent was from BEFORE I made the wooden jig! Luckily I have 5 of these!

Next time I do one, I'll try an end mill I think.

I finally finished my *almost all real parts Obi-Wan Lightsaber, the only replica parts on this are the booster (looking for one *hint *hint) and "transistor washers", which are both Roman pieces. I also added a tack weld to the booster to make it appear more legit. I may do a bit of weathering on it, but overall I am going to call it done. Thank you again Marv and teecrooz for helping me with this I appreciate all of your advice and generosity.

Awesome! Yeah I'm using roman's as well.... teecrooz I'll be looking forward to hearing more news on the vintage washers as it happens. Bradberry00 I notice like me you've not drilled your handwheel for the d-ring.. I haven't the skills. Is anyone out there able to volunteer a handwheel--drilld-ring-placement service?
