Manic Mechanic is no more but in great need of a reducer bushing

Does anyone know if someone has taken over the production of Manic Mechanic's sprocket adapters and accessories?

I just gotten a new and stronger wheel so I will never need to worry about bent rear axles ever again, however the diameter of the new hub is not the same so I will therefore need a new reducer bushing in order to be able to move the sprocket adapter assembly over to the wheel. So what do I do now? Is there someone else that can make one for me? I feel a bit stranded and don't really know what to do right now...
 
3.5mm = 9/64" just under 1/8"

But if were talking radius = 1.75mm = 1/16"

You should be able to wrap an aluminum skin around the hub until it reaches the correct thickness

IDK maybe another member has a better suggestion

BTW the adapters reducers I see online are 1.5" to 1" and IDK if that will work for you

Maybe, if I cannot find someone that can make one for me. I have also spoken to my local machine shop, but they never have the time. My spare reducer that they will use a reference has been with them sense the middle of may last year.
 
Exactly what hub do you have??
Maybe there's another adapter out there (for sale) that will fit your hub so you don't have to go through all this trouble.

I just checked and the hub is made by "Connect" and it is called "C7.0"

You may want to inquire about hobby machinists at your local hobby shop.

I just gotten a reply from the other shop (We have two here locally) that originally could not do it and therefore said I could contact the other one instead. However they could still not do it so I will ask them again if they know of someone else, like a hobby shop just like you mentioned I will see what they have to say.
 
Yup, bicycle shops usually won't work on Motorbikes - insurance reason

I know. But these where not bicycle shops, these where general CNC shops.

At some point, it might be easier (& cheaper) to simply lace in a different hub that has known available hub adapters (or bolt on sprockets).

I know, but I have already paid over 100$ for this new wheel that has been sitting here for over a year now. But to find something else can be very difficult as well because the hubs/wheels that are available here in Sweden is not necessarily the same that are common grounds in the US. Finding the stronger/better wheel I have now was by itself a very difficult task. It was the only cassette based, non disc brake, 26" wheel I could find at a decent price that also had the correct form factor of the hub, and that was all I really cared about then because I was just going to order a new reducer bushing for it so it didn't really matter at the time what hub it was as long as it had a flat surface to mount the adapter on. The very same month that I was going to order it I was told they had just shut down...
 
Reach out in your social network to inquire if anyone knows a retired/home machinist. Guys like me, who own milling machines, metal turning lathes, and all the support tooling. They are out there. I heard of one machinist who would work for free if the client would sit and visit.
I generally work for beer.

I took my 1.5 adaptor to the machine shop with the sprocket mounted. The machinist chucked it up on a lathe and got my size 6thousands under. Cost me 40bucks My size needed is 1.65

I added a set bolt as well.

So in my case went under-sized then calculated where it needed to be.

I see what I can do, I have some places that I'm thinking of asking...

Your bike look good and ya probably had a few fitment issues building it,
I find it hard to believe your having trouble figuring out how to DIY and make a reducer

Oh well, good luck to ya

Yes there was quite a few fitment issues, carburetor and fenders where definitely not easy due to various reasons. But yes, I'm also thinking of wrapping some kind of metal around the hub to fill out the gap as suggested earlier. My only concern about it is slippage, but perhaps that is not an issue if done properly and tight with Loctite and all...

That looks really nice! And a great solution for that case. I have never seen an hub adapter with a set screw before. Where did you get that? =)
