Thread in wood

Hi Don't know if this is the right place to ask, but can anyone point me in the right direction for ways to make a short thread in wood. Its for my father to repair a hinged mirror, I've been on Google and can't find anything really suitable. TIA Anthony

Hello Anthony,

I doubt that it is worth the cost for one thread to repair a hinged mirror, but my book, "Making Screw Threads in Wood" is a good place to start learning how to make threads in wood. If you can't find a copy of it anywhere, I have a few copies on hand for sale. If you are looking to make an internal (female) thread, the easiest way is the use of a tap. You can tap wood if the hole has some endgrain and some side grain as in a flat board. However, the wood needs to be fairly hard, pine for example would be way too soft. If you are talking external thread in wood a die or screw box would work. If it is coarse thread, one can actually layout the external thread and then cut it with a chisel or file.

I hope this helps you a bit.

Thanks Darrell.Robo and Fred. I've had a word with him and its for an external thread for a wooden 'bolt' that fits through the frame into the surround that holds the mirror. He has borrowed my Tap n Die set to have a try at making the part. Thanks again for your help. Anthony

the only mirror I have with a wooden threaded part is quite old, the thread is around one or two threads per inch. Nothing a modern tap would help with - it might be worth trying to get some idea of what these threads look like

Hi William, It seems there 'was' a thread and bolt there at one time, but damage by a few repairs and heavy glue use have made it impossible to measure any remaining thread and a new piece will have to be inserted and re-veneered to try to hide the damage. So he hopes that any thread will work on the new bolts and inserted pieces. If the thread was as you describe and he decided to try and match the way it was, is there an old tool or way of making the threads that size? Thanks Anthony
