Ok you are probably as tired of hearing about wooden screws as I am of trying to make them. This will be brief.
New method picked up on this blog.
Pretty self-explanatory. This method has much less room for error than my previous method.
Basically, a lead “screw” I laid out and cut by hand attached to my blank via a coupler I made. I made it octagonal so it looks like a nut. The lead screw uses the same “false nut” the tap uses to advance the whole thing at the proper rate.
Where the action happens:
So what’s the verdict? These are the best results so far. Quite acceptable. I mangled my first blank but I made some adjustments cutting the second screw and it went a lot better. On one part of the second screw I cut it incrementally and I think that helped a lot. The ability to do so is one of the strengths of this jig.
Here is the good side of the screw:
And the rougher sides:
Not horrible, I don’t think. I can file and sand a lot of that out.
And here is the bottom line…. does it fit the leg I tapped?
I’ll run a couple more screws before moving on but I think I have what I need to make my vise.
I’ll make some more adjustments to see if I can’t eliminate more of the chatter I’m getting.
Another great thing about this jig is I made it to fit the dowels I order online. All I have to do is drop a blank in and start cranking. After that I need to make and attach a hub that I’ll turn.
Thanks for watching and for your support!
