going on to be known very well
i trained as a cabinet maker joiner had loads of jobs got married 2 kids
then wham i was issued a downer i was diagnosed as having primary progressive m/s
not letting this take over i worked for a while before i had to give up
reason for another update
so now i have a nice woodworking workshop with all the usual machines and tools
at the moment I'm looking to make a table that will adjust the height with a turn of a handle
now i have got the normal thread off to a tee but no luck with the left hand thread
so any help would be great

Hi cyme - welcome to HomemadeTools.net :welcome:

Good to hear you are working hard on your projects.

I would suggest to post your question in the Tools in Progress subforum, and I'm sure you'll get some good ideas about the left hand thread: Tools in Progress
