I want to make a wood screw for a vise(2in. dia). I have tried using
dried and green oak and 3 tpi. The threads for the nut cut very nicely
but the outside threads are a mess. Lots of chipping and tearing. Is it
the wood, the tool grind ,or me? I have also tried cherry and it was
worse than oak. My brother ground the tool for the inside threads and I
ground the tool for outside and am a relative clutz so I hope it is
just the grind.
Anyone with experience doing this?
Thanks,
Bob


Seems to me that using a wooden screw for a vise is something you would do
if metal were not available. The only time I have seen wooden threads is on
broom handles painting poles and that is the usual point of failure.
