Thickness of motor mount

mounts

#1

Hey guys, I’m making a motor mount myself for my first build, and I’m wondering what a good thickness would be for a motor mount. I made the one in the pics out of 1/8 inch aluminum, and it seems to be super strong, but I’m thinking I may double it up to make it 1/4 thick… Let me know what you guys think!


#2

I’m using 6mm aluminium and that is definitely not going to bend


#3

Alright, that’s about 1/4th inch. I think just to play it safe, I’ll double it up.


#4

Typically the pulley ends up far towards the end of the motor shaft with a thick plate. If you can make a recess for it then it’s not as far along the shaft. Add a recess for the little c-clip on the shaft and u can get closer.


#5

If you made it a bit wider you could have just put a bend in it. It would have served as a bash plate and made it many times more stuff


#6

I garrantee that you are wrong on that one. I use 6mm aluminium brackets on all my builds and i have bent quite a few. I’ll put up some pick later.


Bend motor mount
#7

Must be some weak aluminium. I bought some premium stuff and it is extremely hard to bend. The torque from a motor and some regular hits will not do anything to it


#8

post some pictures! lets see this thing. 6mm is a lot easier to machine and mill.


#9

what do you mean by a bend?


#10

Hard to explain but if you made the mount 1/2 inch wider you could have put a bend in it under the motor to act as a bash plate and stiffen it up kind of like an I beam.
It would look like an L on its cross section .

Get it?


#11

Dont get me wrong its tough and the torque from the motor alone wont bend it. But this is skateboarding. Its rough. You only have to hit a small rock at speed… just trust me it will eventually bend.
BUT. its also easy enough to bend back.

What i am saying is Anything less than 6mm isnt going to survive.


#12

Ahh, yeah that makes sense.


#13

I get where you’re coming from man. I think I’m gonna start with a thinner mount and see how it holds up. If it’s getting to the point where I’m fixing it after every ride then I’ll move on to something bigger and stronger.


#14

Do you know what grade aluminium you are using?

I using 6060 which is one of the stronger types. I have some weaker al around that is a much cheaper grade and I can bend it by leaning on it


#15

Not sure. The label says nothing other than everbuilt flat bar aluminum


#16

Im using 6060. It can bend.


#17

Must be a different alloy or something. I can stand on mine and it won’t bend


#18

Send it to me and ill send it back bent. I Promise.


#19

With the right tools you can bend anything - so whats the point? If it is strong enough for his purpose everything should be fine.


#20

I never said dont use it. Infact I said I do use it. The point is that I go out of my way to provide expert advice that is only good if you take it.

Also keeping in mind that this is the same guy I went out of my way for to mail a spare circlip for free!
