After years of trial and error, I found that the best way to keep my screw driver up to speed and ready to use any time is using a piece of perspex with 3 grades of 3m adhesive sand paper stuck to it and a bergeon 2461. It's quick and easy. I have a horotec sharpener as well, but this way is great. This is where I got it from

I have one of these rollers plus a large amount of abrasives and personally find it useless. If you can control your moves all you you need is a 2 strokes on $1 alluminum oxide strip to bring back to perfect shape a driver tip that has not been abused.

    • Hello Tom and welcome to the forum.
    • Hah! Well, California will have to do. Lived in TX for a brief period back in the early 70s, though, so maybe that counts. 🙂 Funny you should mention making vacuum tubes- I've actually tinkered with that! It's REALLY tough to do, and I've never made one more complicated than a simple diode that barely worked, but I have played around at it. But there's just no infrastructure for vacuum tube fabrication. I can get a lathe and learn how to use it to make complex parts, and while it might take a while to learn- and money to get the equipment, of course- it is possible to do more or less "off the shelf". But vacuum tubes, not so much. There are a few folks out there doing some crazy cool work with bespoke tubes, but they have setups that are far beyond what I can manage in my environment and it's mostly stuff they built by hand. I also have been playing with making piezoelectric Rochelle Salt crystals to replace ancient vacuum tube turntable needles- nobody's made those commercially for probably 60 years. I'm a sucker for learning how to do weird things no one does any more so I can make things no one uses work again. (I think this is drifting off the topic of lathes, lol).
    • You shoulda been born in Texas. Tough to make a vacuum tube though. You can substitute with a MOSFET eq ckt I guess. I was playing around making a pinion the other day. More to it than meets the eye.
    • Well, turns out it was a fake bezel! The crystal is domed mineral glass and I was able to find a cheap replacement that should be here in two days.  I used my crappy little press to pop out the cracked crystal, Ill give the case a good cleaning in the meantime and do a once over on the movement.
