DIY Motor Mount Adapter for Cronins

Count me in for two of those bad boys!

Two for me as well, when you are ready!!

Alright sweet!

This comment keeps me awake at night lol. I was really happy with my build, but now I can’t stop thinking about what a Vanguard with Ronins and ABECs feel like.

Will there be an inward mounting option?

@Jinra I’m sure I can make it happen. I’ll flip it around tomorrow and see what it looks like. It will most likely just have to be longer.

@FlashNova I just finished a vanguard, was planning on putting the CRonins on a cheap drop down, but now I’m thinking about buying a Poke.

Give me about a week and I should have everything nailed down.

that looks really great! definitely would want the inward mounted version though. should be easy to calculate the required center to center distance with my speccs: 15/36T 280mm

edit: calculated a 72-75mm center to center distance! that seems to be the absolute minimum distance from my pov!

I’d be in for 2 inward mounts :grinning: Though it would be awesome if it was just reversible Any chance of getting a couple of those axels too?

Looks good for inward too. I’m going to make it a 280 belt for both inward and outward I think. A little extra clearance can’t hurt.

motor ground clearance is very low though - fits your board drop version, but for most boards you’d want more motor clearance, else you cant ride up to any sidewalk anymore!

ist basically what I wrote earlier: if you reduce ground clearance, you can fit any mount length … but imo 280mm is the minimum distance for a halfway reasonable ground clearance for 63mm Motors.

Yes, it’s pushing ground clearance. A 280 belt should be fine though. It’s just a 3D print away.

@whitepony Have it set now at 73mm CTC with 6mm travel to tighten and loosen in either direction.

Do you have a non-drop deck you can mock up? I think a lot of us run flatter decks and I would like as much ground clearance as possible.

Thanks for all the work you are doing, looks great so far. Also, I would be a fan of a thinner stainless steel mount but if it’s aluminum 6061 would be ideal.

How’s this? Loaded Vanguard.

that sounds perfect, Id be really interested in some mounts myself - could maybe ship them with a customs declaration of 22eur so I wont have to pay anything ontop! :slight_smile:

id be very interested in black anodizing too since I always need stealth items and silver aluminium is too much bling, catches the eye right away! :stuck_out_tongue:

So CTC goes from 67mm to 79mm correct?

For a 208mm belt with a 16/36 tooth gearing CTC would be 73mm. I left 6mm on each side so yes, 67mm-79mm but you have to take into account the thickness of the mounting screws.

I’m in for a pair myself. If there are more EU people then happy to organise group postage from the UK. Also like the black anodised idea - bling not my thing :wink:

started setting up a 2nd cronin adapter for my DIY bamboo gfk board. last time worked out very well, however I felt like I had a very small misalignment between motor and wheel, maybe 0.5° off or so. getting ultra precision alignment isnt too easy - the “fix both pipes to the aluminium angle” precision is pretty ok, but, while it might have been aligned prefectly to a parallel axis to the truck hangar, it was not perfectly aligned with the actual steel axle of the wheel.

but I had an idea to fix it and it worked out very well!!! :smiley:

since I use slow curing epoxy (24h cure time at 20°C), I set the aluminium profile casting setup up last night and this morning, about 6-7hours later, I checked the viscosity of the epoxy. I was very happy that I could still leave fingernail marks, but it was cured enough that it properly fixated the pipe to the hangar already.

I removed all the aluminium angle alignment stuff, actually mounted the motor mount a bit too close to the wheel so that, with my best aligned wheel-pulley-combo tightened down, I would put pressure on the motor mount and probably push it towards the kingpin by about 0.5-1.0mm. I fixated the motor mount properly, and started to tighten the wheel carefully. when the pressure between wheel pulley and motor mount built up, I could see the motor mount aligning perfectly with the wheel pulley thanks to still fairly soft epoxy.

its curing now for the last bit and tonight it will the best aligned motor mount wheel pulley combo Ive ever used! :slight_smile:

great post mate ! happy to see that the adapters made it ! I’m actually working on a custom mount for Ronin; only issue is that it’s easy to mold with epoxy but to get the part in 3D is really a shame. I may look to get a 3D scan of the Ronin Cast hanger. take care!
