Yes, I've googled the heck out of it. The most common "large" size is 1.5" here in the U.S.
My question is, have any of you actually seen, or know of, the 1-3/4" wood threading kit ??
And, no - I don't want to make one, and no, I don't want to use a router or lathe to do the job.
And, no - I don't want to spend 800 Euros for the Dieter Schmid's 44mm set.
I'm just wondering if any of you have actually seen or used the 1-3/4" model yourself. (of any model or brand name).

Homemade versions can be fraught with frustrations and disappointments due to the fact that the male and female threads MUST match perfectly in order for the mechanism to work properly.
1-1/2" Common Tap & Die
And, this is how it should work with a little fine-tuning.

I got into this back when I built my workbench & toyed with the idea of 2" wood vise screws.

Anything over 1/2" that I've seen are home made jigs.

 

[Steve Neul]

I wonder if it would work to use a metal cutting set on wood.

The male end could be done on a metal lathe. The tap, you may have to get a machinist to fabricate. Depending on the project that might also be possible on a lathe if the part would fit the chuck

 

[John Smith_inFL]

Steve - nope.

 

[_Ogre]

Do tell, John. What are you planning?

 

[John Smith_inFL]

actually, I have several potential projects in mind that can be made in my little hobby room with minimum tools. The one at the forefront now is a portable 2x2' work bench with vise that can be carried in the car and used just about anywhere. The wood threader that I have now is a 1" - I want a heftier size of the 1-3/4" for other projects.
Workbench example:

and this is the vise screw I made the other day with a 1" maple dowel just as a prototype. So I'm chasing the unicorn of a commercially made threader in the 1.75 - 2.0 inch size just for funzie projects. (without having to take out a loan from the bank).

John this guy has the goods on what you want to do

 

[John Smith_inFL]

sorry - that tutorial is of no use to me. I'm not looking for any info on how to make the tool.

Searching around the web everything reasonably priced stops at 1 1/2. Look at the bright side, a 1.5" cylinder has 2.25 times the cross section of a 1", that should be a hefty jump over what you have.

Interesting video if it doesn't answer your question.

More than likely if you want a die and tap set larger than 1 1/2" you would have to find someone to custom make one. That could get really expensive.

 

[John Smith_inFL]

Bob - I contacted Taylor Tools to see if they had access to the 1-3/4" cutter. Got their reply this morning.
I've also contacted a few other companies but haven't heard back yet on them.

.

I'm looking for the tool itself; not how to build one or use one.
The larger 1-3/4" is 50% cosmetic enhancement of the project and 50% function. Eventually, I'll probably add the 1.5" to the box, but not at this time.
Soaking the blank in oil was educational. But later, I saw that it makes the wood swell and might not not fit into the tool. So that takes some trial-and-error there.
I've already put hours and hours of research into this quest - so I've probably seen all the relevant videos already.

John,
I'd be very surprised if such a tool exists. I'd also be very surprised if such a tool would produce satisfactory results.

In my research I have found wooden threads in 2 1/2 diameter and 3 inch diameter.
Example;
Wood Vise Workbench Screw from Lake Erie Toolworks

In the above example, those particular threads were produced using a "milling" operation rather than a cutting die or cutting tap.

"Milled threads" are quite common in large diameter applications, due to the physical limitations of the cutting forces encountered, when attempting to create large diameter threads, using a "tap" or a "die".

I don't know where the diameter break point is, between "tap and die" method to "milled" method. Based on tooling that is readily available on the market, it would seem 1 1/2 inch may be the max diameter where it is practical to use the "tap and die" method.

 

[John Smith_inFL]

yes, they do exist. BUT, the ones I find are made in Germany with no US distributors and they are priced way out of the range of any hobbyist. The top photo belongs to one of our colleagues in Norway and he makes some pretty impressive projects with it like a book press, bench vise, etc. He is the one that has inspired me to try to find a threader of that size. But it looks like the search will be fruitless. My original question was to find someone that actually has one or used one of that size to compare notes. (I think the Euro is about 1:1 to the USD).

.

Lake Erie Tools is one of the companies I contacted. On their website, they don't sell cutters, only the finished products (there is more profit in selling the milk than selling the cow).

 

[Dave McCann]

John,
Would milling your desired threads be a viable option for you? I see you have already ruled out other methods, sorry.

 

[John Smith_inFL]

sorry, no - I want the hand operated tools. No router, CNC, mill, lathe, or other machines will work for me.
I DO appreciate all the effort from everyone - for now, I'm totally focused and driven for the tool only or to find someone that has one or has used one to compare notes with.

I sympathize. I've ended up getting the Taylor Tools 1.5" and it works great, is beefy, but the thread count seems too high. Like you I looked everywhere for something I could afford.

I soaked the dowel in linseed oil for a month, and the thing cut the maple like butter, with no bad threads and no dulling of the blade... So I think you could go much much bigger by hand with no problems. Good luck.

 

[DrRobert]

John, do you know a machinist? I don’t see why it couldn’t be done on a machinist lathe.

Maybe there’s a member here who could do it for you?

 

[John Smith_inFL]

Robert, there are no competent machinists in my area that I know of - only tourists on top of tourists on top of tourists.
There is a family owned place in Winter Garden that I'm going to take my 1 and 1.5" cutters to and see if they can make a set in the 1.75 or 2.0" size at 3TPI. The trick is having the male (die) and female (tap) threads mate perfectly or it will be time and money wasted. There are so many home-made "threaders" for the male dowel part but not many of the videos show making the competent male tap to marry the two together.
My game plan now is to go ahead and buy the $800.00 Tap & Die from Germany, make two 24" Moxon Vise screw sets out of some expensive and exotic hardwood and sell them to you for $750.05 for your workbench. And, that will put my purchase in the $49.95 zone as advertised on the net for the smaller models. (that's my current plan).
After I get the cutter, and get some practice cutting hardwoods, I can see a small market for the Moxon Vise components in something other than white maple or birch. Something I can do on the hobby level to stay busy. (and make a little pocket change).

 

[SonnyAgain]

John, will 2" do? I have Dieter Schmid's 2" tap and die set.... 2.5 threads per inch. I needed this size for repairing 2 vises, one each on 2 antique work tables. As jscseattle said, soaking the stock in oil makes cutting much easier. I soaked my stock in mineral oil for a week, then threaded them. For the nuts, drill your initial hole, then soak.... allows the oil to penetrate the area to be threaded. For the screw, soak the stock in a tube, I used a section of 3" pvc pipe.

I can likely make a set for you, if 2" will do. I have some 8' lengths of 4X4 air dried ash. I'd need some specs of your needs.

Thanks for the response, Sonny. I'm not looking to buy the parts, I'm looking to buy the tool itself so I can make my own.
But, if you wanted to sell your set, we could discuss it via PM.
I only found about soaking the set in mineral oil this week - Never heard of it before. Now, I'm wondering how you get the oil out of the wood if you wanted to stain or finish the pieces (for whatever reason). Just a thought. (and yes, 2" is a very nice size).
