POTD- PROJECT OF THE DAY: What Did You Make In Your Shop Today?

Decided to get a new welding helmet. They now come with removable batteries instead of being welded onto the circuit board so I managed to finish the boring jig.
Set it up and ran a test bore.

It worked a treat until about 3/4s through whereupon the auger popped out the side.

Grrrrr however It may work ok if I go in half way from each end.
Tomorrow will see.
Looking down the bore there is a sharply defined kink where it started to deflect.
I think a gun drill may be the final answer or maybe a "D" bit.

I’ve attempted long drilling in metal before, that I should have just let the boss send to a gun driller.

With that said, I have learned that in steel anyway, it is helpful to have both the lathe turning, and the drill bit turning opposite by a hand drill, and the drill bit would help stay centered better. I mounted an air drill on the tool post carriage to achieve this on my work lathe.

I’m not sure how this would fair in wood, but maybe give you an idea to try.
