Finding all of the small parts for the rear caliper was difficult. I found two NOS brake pad pins and they ran about $60 with shipping. The joint seal (it's a squared o-ring) was super tricky to find but I got one for about $20. I could NOT locate a brake pad spring or the pad shims so I bought a Goldwing caliper and hoped they were there. They were. I got everything cleaned up tonight and threw it together to see how it would look. I still need to order a rebuild kit and new pads but those will be easy to find. This is the gnarly GW caliper.

And here's the 750 caliper that Jerry hooked me up with. Thanks again Jerry.

Wow! It's coming together nicely, Chris.

Here's an update. With the rotor bolted to the hub, the caliper needs to come to the right a fair amount and the left side of the hub hits the inside of the left shock.

Rotor hits the right side pad but there's a lot of space between rotor and left side pad.

Caliper looks like it would need a fair amount of machining to move to the right.

I installed a 77 swingarm that came with the axle (thanks Don) and I found the stock left and right side spacer and put that all on last night. Problem now is there's too much room and the hub and caliper slide left and right. Cmsnl shows that 75/76 and 77/78 use the same spacers but a different axle. Should I use a 75/76 swingarm and have everything back there from the same years? Should I try a 75/76 axle with this swingarm? Thank you for any help because I feel like I need to get everything lined up back there before moving any further.

With the rotor bolted to the hub, the caliper needs to be a fair bit more to the right and with no spacers at all the hub hits the inside of the swingarm on the left side as well as the shock. On the right side, the caliper also hits the inside of the right shock. I do not see this swingarm working unless there is some machining to the caliper and hub and I'm not willing to do that.

I have a 77 swingarm that came with the tensioners and axle (thanks Don!). I ordered the left side spacer as well as the spacer that goes between the caliper and hub to see if that would work better.

The other thing I'm not 100% sure on is whether or not I have the correct spacers. This is what I have for left and right.

Ok...progress was made tonight. I had a feeling there might be an issue with using the 77/78 swingarm with the 75 hub and caliper so I bought a used 75 swingarm and it got here today. The swingarms look the same but the 77/78 is offset by about 10mm on the drive side and the axle is longer (Jerry confirmed this late last night and Godffery was also concerned). I installed the 75 arm and everything bolted up just like it should.

Keen eyes will notice in that second picture that the carrier is a bit further in the hub than it needs to be. Godffery caught that and made me aware of it. I left the spacer that goes in before the carrier gets pressed on to the cush drive on the bench so I need to take care of that. I'll get the swingarm cleaned up and get it all back together Friday night and then get the offset sprockets from Cognito ordered.

A bit closer every day!
It'll be pretty groovy to see how this project comes together, and so far it's look'n Great.

Things look the same tonight but I found some time after work to pull the sprocket carrier and get that spacer inside. Now the hub spins much better!

Not sure what's next.

My mind would wander towards a rim, spokes and a tire. But that's just me...

Not sure what's next?! Oh yeah you are.... get your snow shovel ready

river · « **Reply #83 on:** March 12, 2021, 11:44:57 AM »

That is exactly why I'm not sure what's next. Just waiting to see whether we get 2" or 6' of snow this weekend.

What is this "snow" you are moaning about? We go up to the mountains to ski on it a few months of the year.

Now stop your #$%*ing and order some rims, spokes (and nipples) and some rubber to burn!

This storm is making national headlines.
We got 6" last month and the City shut down for a week, cant imagine 4'!!!

Yeah we’ll see. It’s all anyone’s been talking about for a solid week now. I say bring it.

I got all the bushings pulled from the swingarm and it’s cleaned and ready to get blasted and powdered.

We’re over 2 feet now at the house.

Were it not for the snow, you would have totally side tracked his brain talking about nipples.
Brass or zinc coated nipples?
😁😉

My nipples will be stainless.

Picked up the swingarm and caliper torsion bar from powder today.

They did a really nice job on those-

river · « **Reply #94 on:** March 20, 2021, 07:36:12 AM »

Thanks I’m excited. There’s a cool story (at least to me) on the guy who has done the powder. As we were standing there BSing when we first met he tells me that years ago he did all the finish work for the Yeti bicycle frames (Yeti was a Colorado builder). Then he tells me that he also did the Scandium Schwinn frames. Those were extremely nice and very popular and everybody wanted one because they were done in bass boat metal flake. I rode for the Schwinn Homegrown mountain bike team for several years and had a gold flake and black frame that he painted.

I had a decent weather window the other day where temps were in the 60's so I decided to prime and paint the sections of the frame where things were ground off. Things were looking good until the clear went on. Immediately, it orange peeled horribly. Then we got another storm and now temps are back in the 30's for highs. So I took everything back down to bare metal and started over. I was able to spend quite a bit of time on things last night and today and it's ready to prime again but temps look like they'll be in the 30's for another week so at a stalemate. Also decided since I had time that I would fill some of the low spots from where I did the grinding. God I hate bodywork and paint.

Also was able to get all new bushings pressed into the swingarm today.

Bummed to be on Spring Break and not able to get much done but we needed the snow and this will help make summer gorgeous.

Cant you mount a snow tire and make it a snow machine?!

RAFster122s · « **Reply #98 on:** March 23, 2021, 09:16:24 AM »

Jerry, you still in the islands?

From dissimilar metals and galvanic corrosion point of view is it better to use on Chrome rims a Zinc plated, brass, or stainless nipple?

When using aluminum rims, what is your best choice. It will Not be Stainless on aluminum rims as you are going t have a very reactive combination and the poor aluminum is going t be the reactive loser being consumed if any galvanic corrosion happens.

Ever looked at gold leaf techniques?
Wonder if she would like real gold nipples?

Yes, here until 4/18 then off to the Atlanta area for visiting and the Manufacturers Cup races in Valdosta. Back to CO 5/7 to tinker with the bikes
