Ok, thought you were going to make an L out of 2 flat pieces...

That should be fine, have fun making it. Will you do it by hand, or do you have access to a machine?

by hand

You need to figure out how to square it up too. If by chance you get a piece of AL Ang extrusion that is actually 90degrees, box it up, and bury it in the yard, cause its worth its weight in gold! Most of the time, the angle is less than 90, so you can shim under one edge to get it sit square. Best method is to find a piece that has been machined square.

email from mike:


Me: Hey mike, im getting a second hand Cen matrix TR FRE edition. im wondering what is the smallest and largest pinion i can use with a 66t spur and your mount. thanks

-ben



Mike:I don’t think there are many pinion options with the 62t spur – I made the mount with the 46t spur in mind (12-25t or so pinion range with the 46t spur). I would guess about 11-14t or less pinion range with the 62t spur.

so thats out of the picture anyways.

will pass on that, with the small spur i would need a 9t pinion to bring speed down to 45-47.... that wouldnt fit either, so i guess in going to make a custom one

[brushlessboy16]

how much pinion-to-spur flex would i be expecting without the mount tied into the CD and what are the effects of this?

[brushlessboy16]

So far i have on my list

12x12 .125 kydex sheet

m4 tap, and matching drill bit

90 Degree countersink

Some m4x10 countersunk screws

Some 4x10 button head screws, am i missing anything?

Unless metric are different from SAE, thats actually an 82 degree c'sink. How much do those run BTW. I just get them from work.

[brushlessboy16]

all metrics are 90 degree

im ordering all this stuff from McMaster.com



also added some 3/8x3/8 delrin blocks to mount the tray to the chassis, thanks mike :D

[brushlessboy16]

Good news, im at school now- just got acces to our cnc end mill :D:D:D



so the motor mount will be machined instead of done by hand- maybe some custom odds and ends- we also have a cnc lathe




Cnc machine is:
