[imagedude]

Has anybody here had any experience of using indicator crayons or markers?

I have used them for welding. I was working in a work shop that made scoops and such for Catepillars.We often had pieces that had to be preheated before and after welding and we checked the temp with crayons like that. It works fine with big objects but since knifeblades are so thin, usually, it gives you only few seconds to deside the temp...

Tempersticks are good for helping in "tuning" your eye I found, sometime I have used a piece of scrap and a temp crayon to expieriment with the forge and lighting in an effort to find a colour or some other indicator of a particular temp I'm looking for, before going on and heat-treating a blade. I find them reasonably handy.

I figured if I hung out here I'd remember how to spell words right again, like *colour*... I'm from Canada originally

It's good to see you here too. Maybe somebody should in invite Larry Harley over and see what happens to his spelling...?

If Harley turned up ...... Harvey will lose his crown as King of the bad spellers :D
