On the weekend I got to test fit the 3D printed version of the press fit mounts.
The plan was to be able ride them but I didn’t have the right screws and I didnt finish the support bars which I think are needed with a 3D printed mount to reduce flex and load on the mount.
So I had to remove and put my old setup back on for now.
On the positive side, the marc88 motor plates fit good, the angle is good and @dickyho pulley can also be made to fit 70mm axles with a little modification.
Didnt have enough M4 x 20mm bolts.
Dickyho with chamfer mod to fit.
So I learnt a few things with the test fit.
- Distance between motor plates is 168mm. Should be good for 80mm length motors!
- They are designed to fit faboy 36t and up pulleys, but dickyho pulleys can also be made to fit with some elbow grease. This is with standard 70mm axels. Other pulleys could work but you would need an extra spacer and 80mm axles, then your motor pulley will have to sit out a bit, so not ideal.
- Did not test if the holes work for forward mount but its on the todo.
- Should I investigate making motor plates also? Most of the hard design is done so I think I should at least get a cost on that.
- Note my rear truck is a 45deg, so that may play into the angles the motor plates can go to.
For those who missed the info above, the plan is to do a small group buy of these press fit surfrodz RKP motor mounts. They will be,
- CNC from 6061.
- Fit marc88 motor plates. (Might do my own plates)
- Only fit surf rodz RKP 200mm hangers.
- Fit fatboy pulleys. Dickyho pulleys can be made to fit.
- Press fit, no clamp, as in just do up the axel and they are tight as a
- $50 usd for a set of two, delivered by registered mail from hong kong.
