A Simple Machine to make large diameter wooden screws – cont’d
So here’s a pic of the lunettes in place:
The “lead” (or master screw) and the workpiece are connected with a socket and stub joint that is locked with a screw. The stub should be the same diameter as the socket, close to the shoulder, but should be a little tapered away from the shoulder. This will allow for some very probable misalignment. Remember, we’re dealing with wood here and my shop is 90 degrees with a fair amount of humidity.
Set the router to depth (several passes are probably, but experiment), turn ‘er on and start twisting the lead screw.
Forty odd hours later, $50 lighter in your wallet, here’s what you end up with:
Have fun. You’ll need to experiment a little. But I think you’ll find that it’s very worthwhile.Explore posts in the same categories: making wooden screws, wooden screws comment below, or link to this permanent URL from your own site.
