Hi – you've landed in the right place!
It'd be interesting to know what it is you tinker with. The forum has astronomers, electronics guys, radio hams, motorbike nuts, vintage car freaks, aviation nerds and thats before you get to a hard core of deeply experienced and highly skilled machinists, both amateur and professional. All more than willing to help out.
Oh, I forgot the beekeepers and clockmakers and operators of small gauge railways
