Hi there!
I can hardly believe it that there is someone else out there who does
metal-bashing and uses emacs as a working environment.

"I so agree! I thread and weld pipe for fire suppression systems. we use
 hydraulic calculations; if you can do this you are golden..."

I have a website
weldsmith.co.uk
Lots of technical things.

If you want to get in contact there is a contact form.

Since I wrote that post I have been volunteering at a mine museum making
a replica of the "cage" of the haulage shaft - which for me is getting
my hand back in in welding.

Regards
