Trying to gauge interest in a mount for Cast Ronin trucks. They will be made out of 6061 and most likely anodized black. Mock ups are almost finished and I should be getting the prototype this week. The mount will work both front or rear and although I don’t have a 15mm or a 9mm belt, I do believe it will fit, but I will confirm. I have tested it with a 12mm TB 16/36 setup and it is perfect.
If you are interested, let me know how many you are interested in. I’m working on pricing now, it should run normal mount pricing give or take.
I’ve read some people using 6061 have had their motor mounts bend, especially at thinner widths. I’d feel more comfortable using 7075 as it nearly doubles in tensile strength.
I’ve seen a lot of that too with aluminum motor mounting plates, so using 7075 on the plates definitely makes more sense if the tensile strength really is approaching that of steel as I seem to be reading.
on half inch thick hanger clamps though, 6061 is plenty. So maybe a hybrid approach could be taken if its a two piece clamp system to keep cost down a little.
I personally don’t mind spending a little more for strong mounts, but i can see the appeal in waiting a durable, yet cheap mounting solution. This is probably why torqueboards mounts are so pricey as they are 7075.
The 7075 is a better option, the alloy is slightly different than 6061. The 6061 will hold up to a vertical stress of the motor bouncing up and down with ordinary riding, but where the 7075 shines is the lateral stresses. Even tightening a belt will stress the mount laterally pulling it towards the wheel side, add that to the possibility of hit, the mount can bend at the clamping edge. You can see where it was built up to help minimize the lateral stresses.
