Cutting torch gismos

[oldtimer]

Hi. I'm an old time welder/machinist that likes to build anything that will make fabricating easy. you may have these gismos, but I figure someone would find them useful.
To start with, I made a snap on circle cutter for my Victor 2460 torch. It makes cutting small holes a snap. I don't have to turn the torch as I use a ball bearing that makes cutting easy. I machined a steel housing and pressed the bearing in. I made an adjustable pivot pin that lets adjusting holes from 1" to 6".
