(Completed) First build. Sk3 6364 - 3d printed pulley - single drive - baby buffalo case mod - 6s 5000mah lipo - 120amp esc - epoxy enclosures

like a bench grinder or an angle grinder?

all good, so do you have the flat spots on the top and bottom or on the top and the sides?

You really only need a flat spot on 1 side.

I have one on the top and one at 90 degrees

ok thanks for all your help man!

Hi Chris, Check this method out used for mechanically securing pulleys onto enertion motor shafts, this method probably cannot be achieved at home unless you have special equipment but It might help you with some new ideas.

thanks for that but I’m not using a key hole system but thanks for the suggestion

In that case, this thread might be helpful: http://www.electric-skateboard.builders/t/how-do-you-mount-a-pulley-to-the-motor-shaft/92 it has some information you may already know, but it’s still worth checking out.

My deck arrived today, 40/10.5". I started positioning the electronics. I still don’t have a motor bracket need to finish my design currently drawing up one in 123d and will 3d print prototypes then when i finalise i will ether use my new x carve to cnc the motor mount or get it plasma cut.

I am tempted to modify the board a little like rounding off the tail an pulling in the tale a bit.

Nice! and you have an Xcarve too? man you got all the good toys.

currently building but yes hopefully it will cut half inch aluminium fingers crossed!

game changer! all my brackets have been 6mm aluminium welded to truck, but I cut them with a hack saw and files LOL

good on you! have you every done a clam bracket? i am planning on doing a diy clamp bracket? and where do you get your aluminium from??

I have never done a clamp bracket, I prefer the solidness of the welded bracket. (especialy seeing as I roll 70mm wheels and the bracket hits small rocks a lot) I got the plate from ebay. I think it was this one: http://au.picclick.com/Aluminium-Flat-Bar-6mm-x-60mm-x-300mm-301826607364.html 2 brackets from that piece.

thanks heaps! thats really helpful. I’m thinking of going with the 12mm thick i think that will be enough. i was thinking of taking the approach like the tb clamp mount and the exertion clamp mount. my build consists of caliber trucks so it will be rather easy to get s sturdy fit

true. and having an Xcarve will almost certainly help too!

man… the things I would do…

actually another thing I like about welding is that I’m not limited to squareish trucks.

yeah thats a point but then you have no flexibility like moving them around. Do you get a specialist guy to weld the aluminium brackets? when I’ve finished the cnc get in touch with me might be able to cut you some stuff for you!

I do the welding myself.

will these set screws work? they are from an old surfboard from the fcs fin boxes. They are made out of stainless and have a diameter of 3.9mm

they look almost identical to the ones I use. remember to loctite.
