Introducing A Stagecraft Wiki
I’m starting a functional Stagecraft Wiki for theatre technicians. You will find it at wiki.scenic-shop.com For those of you in the know, the past few years I have been wrestling with creating a community based resource for theatre technicians. Now the same software that runs Wikipedia is being used to manage a wiki by theatremakers, for theatremakers. For those of you who worry about such things, the wiki’s content is (and will remain) free to all....Load Wheels
File this under great hardware finds. - I needed low-profile, high capacity wheels for an effect and stumbled onto these. They are load wheels for a pallet jack (the wheels pictured are Crown part number 44506 / McMaster 2670T58.

Sure most people think math is boring, but that’s because they probably don’t really “get” it. Don’t worry, it’s not your fault you don’t enjoy math....Math

Danger Will Robinson! The cast iron wheels pictured below are the ones that were spec’ed in Keith Cornelius’s 1997 Tech Expo article_An Inexpensive, Human-Powered Roll-Former_. (Grainer part numbers are #3G262 and #3G263.) Obviously they’ve changed a little bit since 1997; the new “feature” is a crown to the surface of the wheel. Unless you’re looking to mangle your steel whilst bending, I suggest you find flatter wheels. I suggest finding flatter iron wheels through Mcmaster-Carr....Solutions
