Title: Home Made?
Post by: Badknuckles on August 30, 2013, 06:14:27 PM

This is one tough screwdriver.  Is it home made? A school machine shop project?

It could be homemade or a school shop project easy enough. I think I recall Crescent made one in this pattern. At least I think it was Crescent. I know someone did.

 One thing is for certain. If you have it in your pocket and fall in the creek? You gonna drown!

I googled >Cresent Screw drivers< and  >Cresent all steel screw driver<

got these  sites but didn't push any further:

Mine does resemble the handle shown.

I went through a bunch of "thewitts" photobucket and it looks like he is one of us. Anyone know who he is? He has some cool wrenches.

As an ex-teacher of metalwork I can say that this was a favourite for many boys to make - I have several I made myself as a kid - centre lathe work (facing, drilling, knurling), screwcutting, forging, bench filing, hardening  and tempering - only drawback the handle often unscrewed when undoing tight screws - clever lads cross drilled and put a locking pin through the handle - drilled, countersunk, rivetted and turned smooth in the lathe..... Lots of processes to be taught/learned....

This is one solid piece.

2 things made me think it might be a shop project; the hole as shown, presumably for a lathe tailstock, and the blade was not exactly symetrical.

However, I have a lot of commercially made screw drivers and not one of them is symetrical - there is a slight offset of the blade shoulders. Why is that? If they are forged I'd thing the die would be symetrical. If I had to guess I'd say it was a stress relief offset.

You might never notice or think about that offset unless you looked for it.
