Threading a piece if laminated wood

[gerry maddenParticipant @gerrymadden53711]

I’m trying to put a 1.5mm metric form thread on a piece of laminated beech. Using conventional tools, there is too much tearing for my liking.

I “think” what I need is some kind of high-speed cutter mounted on the tool post.

Does anyone know of a device that I could buy to do this, or suggest ways to improve the quality of the cut surfaces using conventional techniques?

(I’m not looking for engineering perfection by the way, just something that most reasonable people would recognise as a thread… if you know what I mean!)

Saturate with superglue may work

Dremel in the toolpost will do it with an engraving bit.

Also not that wooden threads are a completely different angle usually closer to 90deg than 60 so that they have some strength.

What do you mean by conventional tools? If carbide inserts, they might not be the most effective. My first choice would be a well sharpened hss form tool with some back rake to give a slicing action.

I would start by increasing the pitch by a lot.

If that’s a 1.5mm pitch thread, then the OD looks to be in the region of 40mm. That’s a rather fine thread in steel or brass…

Each and all of the above posts are rules to follow. Include all of them and you should get a better result.

There is a tool for threading wood which is quite expensive for the odd job it is the Simon Hope Threading tool
