MJPriceisright said:yeah we have established most of the elements here.. but the big concern is the new angles of pressure applied, which will be different now that im bracing a drum with it. essentially it could twist and break.. definitely going to do some bracing using the large caliper mount hole. going to start with the crappy drawing i had made up.. steel brace running up to a bushing welded at the top, having two points bolted to help reduce the twist.
Karlloss said:Obviously you've made your choice, but I can't see where the 'new angles of pressure' are coming from. The drum is only subject to same rotational forces as a disc brake would be.
Rich Ard said:That's not the case, though - using those mounting points introduces a new lever in between the drum stay and the caliper mount, at a sharp angle.
Karlloss said:Bert, yeah right. Point is the top mount will be fine!
Bert Jan said:No its not. Do your homework instead of giving false, potentionaly hazardous information.
For instance, the calipers that used to be on those forks were held secure with 2 bolts and so, the force was divided over the 2 mount holes. I can name a dozen other reasons, but point is youre wrong.
Karlloss said:I did my homework thanks. Does it matter now as the decision is made.
Your opinion is exactly that..yours....and you know what they say about opinions.
I guess my qualifications in mechanical engineering are potentionaly hazardous information
With all due respect, this is a myth that needs to be dispelled. For any given diameter of tube, the strength of the tube will increase as the wall thickness of the tube increases, all the way to the point where the tube becomes a solid rod.Bert Jan said:A hollow pipe is stronger than a massive one with the same diameter for the same reason.

Here's a simple online calculator that calculates the deflection and stress in square and round rods and tubes. Plug some numbers in and compare.
