like so often, okp was pioneering with motor mount adapters for the complicated cast ronin trucks, whose truck profile changes in a nontrivial way along the way from axle the kingpin!

okp was nice enough to send me a few of his adapters, but they were made for 9mm belts - for 15mm belts you need the adapters even further in towards the kingpin, which is a completely different ronin truck geometry already and which is also problematic, since the max diameter for the adapter is 30mm with the alien power system mount and basically the truck at its widest part is 30mm very quickly.
I liked the way okp did it, but it felt a little messy to me, or well, I felt like I could make this a little simpler.
I ordered 30mm aluminum and stainless steel pipes with a very thin wall (1mm for aluminium, 1.5mm for stainless steel) and cut them in very short pieces - long enough to allow quite free positioning of the motor mount, but short enough that it wont interfere with the wheels. then sanded the cuts and in the case of the aluminium, I actually polished the pipes for looks - left 2 are stainless steel, right 2 are polished aluminum:
I brought the pipe all the way to the kingpin and decided to go for the aluminium, since the thinner wall allowed the pipe to go juust that little bit further that I needed for the 15mm belt:
I added the same pipe on the other side for symmetry and taped both of them firmly to an aluminium angle leftover from my very first enclosures. that way the adapters will be perfectly straight!
another pic to show the 2 pipes to make it clearer, why both of them simply have to be perfectly aligned and straight
used plastilin to seal the kingpin side (its much easier to add resin from the wheel side, because the opening is much larger):
I then used the slow curing epoxy resin I still had from my laminating adventures and added quite a bit aluminium powder to increase the heat conductance of the resin. id like to use the truck for heat dissipation as well, since the APS mount is 100% aluminium unlike the enertion CFK->aluminium mount:
and finally poured it into the pipe:
Im not sure if this will be awesome or not, but if it works out, its a fairly simple way to make custom truck mounts for just about ANY truck - should also work for torqueboard mounts, but they have another diameter … so essentially all you have to do is order smaller diameter pipes.
anyway, Ill keep you updated - tomorrow Ill know more and I hope my APS mount will arrive soon - bruno sadly isnt the fastest - my stuff is waiting since monday for UPS pickup.
