Fellows - where are you buying the squarish pucks?
I think mine are about done.
Creative Engineering is currently in the process of making some top
quality square clutch pucks. Give Jim a call and find out when he
plans to have them ready to sell.
They're comming guys...I bought a 30 inch square sheet of 5/16" thick material from Carlisle over a month ago, ($165.00). Carlisle is a leading U.S. manufacturer of friction materials.
It is for a dry application...It is very wear resistant...These materials are classified in terms of thier ability to grab at various loads and RPM's...the material I chose, (based on a discussion with thier engineering department), should be perfect for the MB's. This material also has a high heat resistance.
I've got to make up a quick set of dies to punch them out...both the round and the trapezoid shapes.
The engines I got a year ago had fairly dense and hard clutch bits...similar to a linen based phenolic...now it's more like ground up underwear bonded with cheeze-whiz.
That will be nice. Mine (bought in late 2007) are made of old car tires, complete with steel and nylon fibers. The inside against the driven plate are shiny and smooth as a mirror. The outside against the floating "bell" are crusty and crumbly.
They need to stay in place, yet slide easily in the gear hub trapezoidal cutouts to grip both sides.
I'm figuring $10 a set...they should last for ever.
Jim
Yeah buddy! Let me know when they are in stock! BTW I wanted to give you a positive feedback on the sprocket adapter! I can definitely feel the difference in overall performance as it has improved dramatically! I had to pop a new clutch on the bike to get it going again so I'll definitely want a set of pucks when you get them. KUDOS Jim!
