Yeah, welds are all good. Guess I'll just fill it in. Annoying

And this, my friends, is why I try to do everything myself.

And thats exactly right. Seems a guys project means nothing to nobody, besides the paycheck anymore.

frame should be ready early next week. I always forget that "it'll be ready tomorrow" means "who knows when I'll get around to it." Anyways time for other fun stuff.

Getting some good use out of the HVLP kit. Laying down some HB surfacer, this stuff is epoxy based and supposed to be the surfacer of surfacers. We'll see.

After 1 coat

Rear fender and mounting bracket primed.

Dent in swing arm is stock. Brake operating arm fits in it when you push pedal

Re: '74 CB 360 Cafe Build - Boomerang

+1 on the dent. Nice build you have going here. I'm a big fan of cables for drum brakes and rear sets myself. Maybe a bit late - missed your build for a bit - but this is how I did something similar - maybe you can adapt some of it to your bike if it helps. The brake end is just what you see. That is an old factory Yamaha part for the cable and housing originally used for a brake. I just made an arm to go between the axle and the brake stay arm bolt and a little block to capture the cable housing end. On the pedal end, it is hard to see, but the threaded part you see that screws into the spherical rod end is just a cut off bolt with a hole drilled through it and silver soldered to the cable. The cable length was set here so that the bolt rest fair on the cable housing end so when the brake is not being applied, there is no exposed cable at all - the bolt I soldered on gets drawn right up the cable housing end. When you apply the brake, you can see the small amount of cable exposed between the bolt and the cable housing. The cable housing end screws to a little steel bracket that attaches to the rear set plate, and another small bracket for the return spring is sandwiched in there at the same time. There isn't a brake light switch - I figured the front switch would be enough. The soldered on bolt serves as the stop for the cable in the "brake not applied" position. The brake itself adjusts normally like all similar era drum brakes at the operating arm. The pedal position in the "brake not applied" mode is adjusted by how far the rod end is threaded onto the cable end. I determined my pedal pressure by keeping the same ratio as the factory pedal to crank arm ratio. I was concerned the cable would make the brake feel mushy, but it works fine - really solid like the original rod. It is a really big, fat cable though.

Great job - keep it going!

It's been a long week of paint prep. Converted the shed into a makeshift spray booth and got the frame and accessories sprayed.

Been closing up lots of other odds and ends as well, got tires balanced and touched up the paint. Still perfecting the fitment on the seat, should have it sealed and primed tomorrow.

Goal is to have this baby back together by next Saturday. I have a yearly get together with friends and family and I'd love to have her assembled by then. It'll be a long week ahead of late nights, but it's always worth it.

Re: '74 CB 360 Cafe Build - Boomerang

Started reassembly. Feels great to start building a painted piece.

FINALLY got the seat fitment the way I want it (after far too many edits). Got it sanded smooth and a coat of epoxy to seal her up.

That seat has been by far the biggest hurdle of this project, but I'm very happy with the way it came out and flat out pumped to get some paint on it.

Could you do some photos of how your actually mounting the seat? In getting close to that point and I'm kind of at a loss.. And what do u plan to do with the cushion mounting wise?

Yeah I can upload some pics later this week on that. It was a pain in the ass, but I basically drilled and epoxied in rubber grommets with threads to absorb some of the vibration. I marked them out preliminarily on the seat to line up with the front battery tray mount and on the cross support, then drilled holes in the frame to line up after.

LOL 8)
Try around 27" total width, (I use 24"~26" on 360's, 26" for road use)

Re: '74 CB 360 Cafe Build - Boomerang

Er, only problem is the tapered end of the master cylinder (I'm using stock) hits the mounting brackets on the clip-ons as it is. If I slide it in any more, it'll just push it out an an angle to where I won't be able to mount it at all.

Hmm. Notch master cylinder?

Re: '74 CB 360 Cafe Build - Boomerang

Do you have to use the stock m/c? There good options out there for universal brake and clutch levers. Definitely options to get your banjo in a better place, where the stock 360 points straight inward.

Re: '74 CB 360 Cafe Build - Boomerang

I don't necessarily, but I'd rather not buy something new since I already put the time and money into rebuilding the OEM one.

It surely isn't a good setup for clipons.

Re: '74 CB 360 Cafe Build - Boomerang

Nope. It's for those handle bars that are "way-out-there."
