Hello again my friends,
I finally got some time to work more on my wooden screw. So here is what I’ve done.
First the layout, same pitch as the tap, I also lay out the groove for the external garter. Then saw to the line. I also used a set of dividers to score a center line between the kerfs. 
Next I use a pencil and my fingers as a fence and mark out a quarter inch chamfer around the tip. 
I sit on my freshly finished saw bench and use my “Leg Vise” to hold the screw while I rough out the chamfer. 
I then smooth out the bevels with sand paper. 
Then I started chopping out the threads with chisel and mallet. 
After roughing it out I go over it whith a square file and then 80 grit sandpaper glued to a square piece of wood.
I did get it to work, and I almost made it through the nut last night…


It takes a lot of trial and error, putting the screw in, taking it out, knocking down the high burnished surfaces. It kind of sucks, I think will leave this method to Hero and Archimedes. I’m buying a router bit to finish this thing off. The good thing about having done it by hand is that I now have set up “block” for perfectly positioning the router bit. See Carters blog with a detailed video of that jig. http://lumberjocks.com/CartersWhittling/blog/29104
So I will be ordering the bit, I may carve it a little more in the meantime.
Thanks for reading!

Wow that does look like a lot of work! Hopefully the router will make short order of it. :-)

That is a long process. I could only imagine. The is another hand tool way to do it though, you can make a threadbox that shaves it down to perfect. Roy Underhil did a great translation of Andre Roubo’s description of how to do this in his book Working with Wedge and Edge…which also contains plans for the bench you are building so you might have seen this already.
Take care and I am looking forward to seeing this come together.

talk about screwing it up! Its still pretty cool the way you’ve worked it by hand, but I think I’d power threw it as well.

Thanks everyone for commenting.
Hey RG, I have Underhill’s book and I havent looked at in in a while but if I’m not mistaken he says that anything 2” and above is cut by hand the way I’m doing it. Those dies they sell cut the whole thread in one shot, not llittle by little (if I’m not mistaken) so the force needed to turn one is too great.
I like to do things galoot style as much as possible because I think its more fun. But we all have our limits I have a day job and the bit is on sale at rockler right now for $12.99!
Also, I’d like to do more in the future so the router jig I tihnk is going to be the way to go.

You are correct sir…but I thought about it and I wondered if you could rough it out first and shave it clean using the die.,.crap, you might as well use the router.
I might as well grab one too.

Do it RG! The tap is easy to make, Your test nut becomes your temporary nut to attache the router too. A very doable project.

That is awesome. Makes me re-think making my own screws. Great info though, looking forward to see how it turns out.

This shows your determination to get it done. Good work. Thanks for giving us a peak at the labor that this takes.

Thanks for the support guys, Its nice to be able to talk to folks that get it. Try telling your non woodworking friends that your making a 2” wooden screw and their eyes glaze over.
Heck, you’ll get that look from actual woodworkers!
This project makes me feel like the Professor on Guiligans Island! LOL

You don’t know unless you try Mauricio. Sometimes the old ways are best and sometimes not. I would definitely go with the router personally. Thanks for sharing.
