Where can I Buy a Tap to suit Lathe?

[Black Ned]

I have a mini-lathe that has a 1" x 10 TPI thread and I wish to make some threaded wooden face plates to suit.
I don't know how to describe the thread properly and am having difficulty findind a supplier of a "tap" to suit.
I would imagine that there are quite a few woodturners out there that have faced this problem and have overcome it.
I would be grateful for some helpful advice.


regards, Ned

Google "thread chasers for wood"
You'll easily find a number of links to videos, web sites and downloadable docs describing cutting/chasing thread techniques.

I was interested until talking to other forumites at the Bris TWWS I found the slowest speed on my lathe is to fast. Pretty sure speeds of 500rpm and under are recommended. I'm sure when true practitioners read your post they'll weigh in. If not, maybe change your post/thread title to "chasing".

I've seen Sorby and Hamlet sell chasing tools in a range of tpi to name two.. Usually sold as pairs for internal and external threads. They are used in making threaded lidded boxes and shaped accordingly. I have seen techniques described for handmade and re-shaped/re-purposed tools too.

How many faceplates do you want? The $ may speak and rule out specialized tools and back to metal faceplates.

You will find the 1" x 10 TPI is non standard, all 1" being BSW or UNC the 8TPI

This done deliberately so as to maintain the manufacturers exclusivity on parts

you may at a pinch find it from a specialist engineering supplies but the price will be horrendous dont expect too much change out $200.

The way to go is to make your own thread via thread chaser. I can help you there as I make my own chasers. In fact I am making a 10tpi for a guy in Queensland next week.

Slow speeds for chasing are the way to go start around 200rpm. If your lathe wont go so slow you can get your mate to spin the chuck while you chase the thread.

Any large engineering supply places or Ebay will carry them or can get one in.

Just ask for an 1" x 10 TPI Tap.

I'd try McJings.

They sell a M30 tap for $22.

They may also have a 1"x10 TPI at a simular price.

I found a couple on the US Ebay site, one is $70 USD plus shipping, the other is from the UK, approximately $45 USD with the shipping.

Thanks Guys for all your suggestions. And Thanks to Tim for suggesting McJing.
I had looked at their online catalogue and did not see it listed but after Tim's suggestion I telephoned. They are currently out of stock but will have some in their next shipment in approximately one month from now. I will get one from McJing.

You might see what 1" x10 TPI nuts sell for. Turn a hole in a block of stout wood that is a press fit on the edges of the hex on the nut, put some good scratches on the nut with 60 or 80 grit, scrub with water and dishwashing detergent to remove any oil, dry and slather epoxy on the inside of the wood and outside of the nut and use the tailstock of the lathe to press the block of wood on to the nut threaded on to the well oiled spindle.

Turn the spindle by hand to see if the disk wobbles and tap gently to get it running more or less true. Face it off after the epoxy sets.

Here in North Carolina, USA, 1 X 8 TPI nuts are cheap as dirt, 1 1/4 X 8 a bit more, 33mm X 3.5 metric are an arm, a leg, and one's first born child. I recall 3 for about $21.

I have bought all sizes and have done the above for making disk sanders and hand wheels, as well as welding on steel plates for a faceplate.
