Large Allen Screw

scollins · Post by **scollins** » Fri Apr 05, 2013 6:37 am

While using my joiner, I heard a noise soon followed by a large (~1/2" dia.) allen screw bouncing on the floor between the joiner and the headstock area of my SS. The SS still worked fine with no other noise. The noise I heard seemed to be from the headstock area. So far I haven't been able to find where this came from. Is there an allen screw that large in the SS somewhere?

There is only one large setscrew in the Mark V that I know of. And it is one of the few setscrews that could fall out and result in little or no noticeable effect.

The setscrew (#9) that I am thinking about is in the headrest (#13) and makes contact with the tie bar (#25). There is nothing like that in the headstock.

Assuming a 'headless' setscrew, I agree with Dusty!

If however it has a 1/2" 'head', then it came off the other end(vertical lock screw/'knob').

There is no way one that large could 'escape' from the headstock.

#18, but they are usually 9/16" hex headed screws.

My money is on #6 in the diagram Dusty posted above.

Scollins said it was ~1/2" diameter, and he only said Allen screw. He didn't say anything about a set screw.

Although not quite 1/2" - check all four screws that lock the main table to the tilt trunnions.

Though not 1/2" in diameter, the original jointers used allen screws to level the blades.

What on #6 is 1/2"? (bushing does not count!)

You're right - I was typing at work and going from memory. And when I got home I checked and it's a large flathead, not an Allen screw.

Dusty was dead on with the call for screw #9. I had to release the headstock ways to find the hole. Thanks for saving me a lot of time searching.

The next question, is, how did you adjust it after reinserting it into the threaded hole?;)
