« Part 14: Wooden Screw - Another attempt Part 15 of Workbench Build - Splayed leg French Bench series Part 16: Leg Vise Part 1 »

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.

Some pics:
The “machine”:

The coupler:

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.

RESULTS:
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?
hallelujah!

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!

Looking good Mauricio. All that patience is paying off. Mighty long screw you have there bud. What else is there to be completed on the bench now?

Thanks Shane. The screw has about 20” of threading which is about what the Lake Eerie screws have except that mine is 2” and not 2.5”.

But I like 2” for a lot of reason.
-I can buy the blank already made
-I don’t need 6”x6” legs
-I’m sure it will work just fine
-And I can use it for other types of vises like a Moxon maybe

Workbench To-Do’s:
Make the Leg Vise
Make the bottom shelf
Final smoothing
Assemble the base
Finish (maybe do before assembly?)

Not much to go now, but you know how that goes. It always seems like less than it actually is.

So when do they ship? :-D

Looking good, glad you’ve gotten a process down that seems to work well. In the end, it looks like a much easier process than some of the other ways you’ve tried.

Thanks Mos! Once I eliminate the chatter I’ll see about maybe selling a couple.

I really hope this works out for you. I know you have a lot of time and labor in it. It seems that you are determined to get this and I believe you will.

Thanks Dave, I think I’m calling it done at this point. There might be some minor tweaks but I’m calling it “worked out”. ;-)

Thanks for the faith Terry, its actually was quite simple. All I had to do was make a bunch of pieces of wood with holes through them glue and nail them to a base. (not counting the lead screw and guide block) Once my Bench is nice and flat I wont even need the box beam, I’ll just clamp it all to my bench. Then it will just be about 6 guide pieces that need to be stowed away.

Purp, thanks my man, and thanks for watching.

So with this machine… you could replicate the TPI on anything that you can use as the lead screw?

If your talking about changing the TPI or reversing the pitch (wagon vise) then yes, I would just have to make a different lead screw.
