I'm currently enrolled in the Mechanical Engineering Tech program at UNC-Charlotte and in my dynamics class we have to build a Rub Goldberg machine. The end result of this machine is to send a wooden block off a ledge to a box located 4 inches from the edge...Kinda like my rough sketch below...
BLOCK________

_____________ |______| BOX |
Anyways, to my point...
I need a finish to apply onto the MDF surface the block is going to slide on, that will allow me to use paste wax and reduce the surface friction as low as possible. I was thinking of high gloss poly to a pretty good thickness then a few coats of wax. Anyone have any other ideas?
I'll try to get the actual diagram of what we have to build, and calculate for, in this machine.
Thanks in Advance!!
