As per my other post, I'm considering buying a small Mig Welder. I will, obviously, need a welding mask and I've been looking at the 'automatic' ones. Some seem very cheap. Are they any good? I'... Read more »
I recently found myself wishing I'd invested in a small welder (yet again*) when trying to make something. So, I'm looking at the options of buying a simple one, suitable for basic 'fabrication'.... Read more »
This ought to be simple so I'm probably missing something. I'm trying to cut a 1.5mm thread on an ML7 with 8TPI lead screw. I have a 127 tooth gear but no 21 tooth. Duncan Munro's Ml7 Gear calcula... Read more »

Since you asked, the Woodward account agrees with your assertion that the synchroniser on a hit acts to increase the force of gravity, although I think it would be better expressed by expressing th... Read more »
Just looking at the mechanism in the master free pendulum, what happens if the two pendulums are PI out of phase, for this suggests that the light gravity link will drop on the wrong side of the m... Read more »

Looks like we will have bought an Oerlikon Solomig M260C Mig welder, mainly for home stuff. Does anyone have any experiences of these welders? Apparently they were made by a company called MaxWeld an... Read more »
