Hey guys I’ve been working on making a kegel press fit pulley that fits Cal ll trucks without modification (of course it will fit other trucks as well) for the last few weeks and I think I have finally have a design that’s almost near perfect! ( still need to make some minor tweaks)
First some pictures of the 3d printed prototype pulley installed-
The pulley uses a flanged 608 bearing that shares a bearing seat with the wheel. The difference between this design and current designs is that the flange physically locks the press-fit adapter into the wheel and doesent rely on friction alone.
Since the pulley adapter and the flange on the bearing take some space away from the bearing seat in the wheel a extended spacer will be included with the pulley.
Here’s a comparison of the regular spacer vs the extended spacer-
The press fit adapter has 20mm long shafts so they should be able to fit regular and flipped core kegel wheels (currently I’ve only tested them with orangatang caguama but I’m open to sending the design to a trusted forum member that has a bigger variety of wheels to test on so they can 3d print it and do test fits. (@mmaner you interested?))
Here’s some more pics of the pulley-
What makes this pulley different?
These will be the cheapest modular/interchangeable press-fit pulleys on the market.
The use of a f608 bearing physically locks the pulley assembly into place unlike current press-fit pulleys that fit Cal ll trucks without modification.( pls correct me if I’m wrong)
The final product will be cnc machined out of 6061 aluminium, anodized black and fit 15mm belts. I’m currently trying to be able to offer them at a pre-order of $35 for a single pulley and hub adapter and $65 for a set of 2 (price has been changed to $50 for a single pulley and $95 for a set of 2). Everything you see in the picture below below plus an additional 3 bolts which I dident have on hand while taking the photo is included with each pulley.
Currently I need to order around 30-40 pulleys to be able to sell them for the prices above (I’m still negotiating with my supplier so prices may change but I’m hoping not) so I will need to run a pre-order.
Before I make everything official and start a group buy thread I want to see the interest in these pulleys so if you can please complete the polls below it would be greatly appreciated!
- I would be interested in a single pulley at $35.
- I would be interested in a set of 2 pulleys for $65.
- I would be interested in multiple sets.
- I’m not interested.
The only tooth count that’s currently set in stone is 40T. I’m open to do a total of 4 different teeth counts which teeth counts would you guys be interested in?
I know this Is not a brand new type of product and a group buy is not always the most preferable way to do things around here but in order to provide the low price that I want to offer them at I have no other choice.
I also want to give a shout out to @moon for allowing me to base the press fit adapter piece off his design.
If you have any questions leave them down below and I will do my best to answer them!
