Topic tags/keywords: trick jigs tap and die wooden threads vise equipment

I have been looking at some of the tap and die sets for wooden threads. There are German made that are approaching $1000 depending on the size.

Has anybody tried using a tap and die set for black metal pipes? They come in various sizes and I am not sure why they would not work and they are ALOT cheaper then the ones designed to be used on wood.

Thanks

Steve

Beall tool makes wood taps in several sizes and a jig for cutting threads on dowels using a router. There are several companies that sell wood tread boxes (die) and tap sets. Most of those look like they are made by the same company and sold under different brand names. There are several of them listed on Amazon.

I have never tried a pipe thread cutters but I have used just regular metal taps to cut threads for machine screws.

It’s wood.. you can use the cheapest tap/die set you can find and they will work just fine.

thats why i am asking what size he is looking for. i use the Irwins from the big box store. they work awesome on wood for $990 less than the German ones the Op is looking at, but they only go so big.

Depends on the size of threads. For large wood thereads its hard to beat the Beall wood threader Lazyly referred to above.

For smaller threads in wood i can recommend the taps designed in collusion with the Wood Whisperer... he no longer sells them but I believe they are available form Eagle America... ok, I don’t believe, I know!

Don’t believe the hype that you can use cheap metal taps… ok, believe it as you can use them and they’ll basically work. The taps I refer to were made for wood and have much, repeat much, and if you didn’t hear that, much better tolerances… FAIW, I did a review of them here… actually there → HERE...! Actually it wasn’t a review but a blog on ”metal threads in wood”... featuring The Wood Whisperer’s taps.

Generally one wants fewer thread per inch for wooden screws than for metal.
The wood movement with humidity requires larger slack between screw and nut. Further than stress resistance, that is also a reason to have less thread per inch in wood.

Tube threading is intended to lock.

I have a cheap tap and die set (China?) It works more or less (I only have made a first test). The quality of the wood used is of course very important. (tight straight grain) Soaking the wood in linseed oil would probably have given better results.

If i were doing lots of nuts and screws with the intent to sell them I would buy the professional German set.

I have to agree with Brad,
Any tap and die set will work with wood, be it hard wood or soft wood.
No need to spend 1k on a tap and die set IMO.
I wouldn’t soak the piece in oil as someone suggested, just tap it dry while blowing a bit of air around the tap to keep the heat down in harder wood.
Myself, have my preferences with taps. I buy either Guring yellow, blue ring work well or OSG hy-pro taps in wood, steel, plastics. I find a spiral tap or roll form tap is perfect for diamters of 16mm or 5/8 in blind holes.
Here are the different styles I use.
The picture will probably come in either sideways or upside down, but you will see the difference in taps.

For pipe taps (NPT) again, Any tap will work fine.
As someone mentioned above, you either need a depth check gauge for all NPT taps, or tap a hole in some scrap to get to the proper thread sealing depth .

Here is a picture of a 1/8 NPT tap if unsure. Maybe it will help.

I have never heard so much rubbish in a thread since my Sideways pictures postings. I opted to baulk with some of my remarks but find it irresistable to set the records straigt…

I will make the caveat that I am looking at strength in wood threads and not just the ability to metal tap in wood. If that’s all you’re after (ability), I apologise and please ignore my rant.

Can I talk with authority of taps in metal…. NO.

Do I tap wood… Extensively.

Do I experiment in threads in wood… YES.

Do you need to spend $999 to tap in wood… NO.

Can you tap in wood… YES.

Are metal taps the best for wood… NO, NO, NO, NO!

Is there a better way to tap wood… YES.

OP, IF you want to tap in wood use any tap, but if you want strength, please read my thread about wood threads... it craps on but it is spoken from the heart and not from my arse. I’ve done the yards and am comparing chalk with chalk. I promissed to make a review about the Beall Threader but the way people here listen to other than cheap advice, why should I bother.

Other than being a bad example for kids, my net worth to society may just be in threads in wood.

PS. You can even “thread in MDF”... with semi-strength! But that’s for the skeptics to refute.

Maybe I’m missing something, but it seems this thread is rooted in incomplete info. We don’t know what Mr Ayotte intends to do with threaded wood.

Because he tagged “vise equipment” I’m guessing he hopes to make a wooden screw vise without throwing lots of money at thread cutting equipment which won’t get used v often. I would say don’t bother with tap & die for metal. The pitch is too slow for the action I want in a woodworking vise. If I wanted a one-off screw for a vise, I’d just buy it. I’ll never use a tap & die often enough to make it worthwhile.

Thank you Sycamoray. Yes, I am thinking of making what I have seen called a Milkman’s workbench or in a recent newsletter from Lee Valley as a Portable Workbench. They go in to great length talking about making a threaded rod using the Beale device. I have also seen a video of the German made tap and die equipment but almost choked when I saw the price. After 30 years of woodworking this would be the first time I would cut threads on a hardwood dowel and do not need a gold plated tool, that I will never use again, to do that. I am guessing the threaded rod for both designs is about 1 inch. I was looking for some thing practical and hence why I asked about a tap and die set for black iron pipe. It would probably never get used again.

Roy Underhill has an episode of the Woodwright’s Shop where he covers making your own. I haven’t seen it but I read one of his books and it had a section on it.

Well… I didn’t mean to ruffle any feathers here if this statement is directed at me.

Are metal taps the best for wood… NO, NO, NO, NO!

I agree, however, depends on fit and function within the project.

Is there a better way to tap wood… YES.

Absolutely, I don’t think anyone would argue that point.

I promissed to make a review about the Beall Threader but the way people here listen to other than cheap advice, why should I bother.

I hope you continue with the Beall Threader I’m sure many including myself would appreciate that.
