Made up a brake rod and fittings.

I had to get some new shoes, the old ones had been buggered about with, to get the brake arm to sit and work right. Then threaded some 6mm stainless bar, turned up the brake rod barrel and nut and bought a rod end bearing off the bay. Also welded an adjustable stop on the pedal, after modicating it to suit the bearing. Random popped round Friday so we had it outside to check the footrests and pedal were all in the right place.

Over the last few days been getting a bit more work done on the Tribsa chop.

I got an old pair of Drag Specialties footrests tacked on, turned up a brass embellishment for the gear lever. Scored a B25 brake pedal and pivot off the bay and made up a mounting lug for it. Had to extend it by 70mm, welded a benchdonkees footprint on it while I was at it. Got the front of the rear mudguard mounted too.

Bitsa frame and fixings.

I cut some curved straps (thanks Jim!) that follow the arc of the rear wheel to mount the Panhead toolbox on. Also scalloped some tubes on the mill to fit the oil tank and fix the rear mudguard to. Got the oil tank tacked in, mudguard next.

Mostly machining.

Turned up a pair of nuts to convert the Triumph rear axle to use the BSA chain adjusters. Machined a couple of clevises (clevii?) to fit the sissy bar to the rear frame.

More progress on the Tribsa chop.

I got most of the unnecessary brackets cleaned off the frame, welded up some holes in the top tube and fitted the headstock bearings with the help of some sleeves. The front end slotted straight in, need to fab some lock stops though. Made up a new cylinder head steady, tacked on the tank mounting bosses and we took it outside to check everything I'd done so far looked ok.
Next job is to mount the the rear wheel properly and work forwards.

I started work on Random's bitsa chopper a while before it arrived here.

He brought round me a set of Ceriani Forks and yokes, a Yamaha hub laced to a 21" rim and a Suzuki tls brake plate. I had to make up an arbour to machine the face of the brake plate down, then open up the slot in it to take an aluminium torque stop which I had welded to the fork slider. Then machine up a spacer for the other side, all to get the wheel to run centrally in the forks. I seem to remember there was also some messing around with bearings and spacers inside the hub to get it to spin without catching the brake plate. No such thing as a five minute job, but at least when the bike arrived it was hopefully going to be a relatively easy job to get the new front end in!
