Dogbytes' R80 ST project

I keep meaning to ask...

I don't suppose anyone has one of these kicking about? I don't need the ring gear or the bearing but I do need the studs.

It's to make the carrier to fit the rear wheel into the wheel jig for tensioning/trueing. I have actually drawn an adaptor up, but finding time to go and make it, well that's another thing. Far easier to modify one of these...

Yesterday's progress

Hours spent doing little fiddly jobs - all accompanied by a nagging fear that the next bit might not fit! :mad:

The final drive went back together fine. The new swing arm bearings went in fine too - except that I then realised I didn't have new grease seals. Fortunately I had an order in progress from Sherlocks so I just added it on and it should be here soon. Just offered it all up to make sure it still fitted anyway...

Today I'm going to make a couple of bits - the spring cups that go under the fork adjusters and the gear selector lever (modifying the angle on the original). I think the wheel jig carrier for the rear wheel will have to be put out to someone else - I just don't have the tooling to do it here. A nuisance as it's a very straightforward job.

It's things like this that take the time and put the price up. The little things, the things that you don't notice or don't even see. However they take hours to do.

In this case the steel bit is the external gear selector part - the bit the linkage attaches to. I need the 'lever' bit to hang vertically, which isn't n option with the standard one. I've chopped the lever off, faced it and turned the o/d. I'll make another lever and TIG it in place.

The brass bits are the buttons which go on top of the fork springs and under the adjuster screws.

Just for a change ...

The gearbox thingy...

The other end isn't attached because the M6 left hand die that I bought doesn't work. It's a piece of shit and I should just have had the rod screw-cut from the beginning. Still, there it is...

Top job:cool:

I spent days and days filing stuff during the first year of my apprenticeship. It wasn't even my trade and I resented it at the time. It's come in useful over the years though.

Coming from Toxteth, I was the same with locks !!:aidan

Superb engineering work Dogbytes.......bike is going to be a collectors item, never mind a race bike !!! :clap

Any skill is worth learning, they all come in handy sometime. As an Armourer/gunsmith for forty years, filing is pretty much what I do. Actually, I find it very therapeutic these days:)

Thanks :) there are some very nice airheads out there and if this one compares favourably I'll be happy!
 
It's all little, fiddly jobs at the moment - it's going to give me an ulcer! I'm also waiting for other people for engineering jobs I could do myself - if I still had a proper workshop. Who makes throttle cables? Got to get from a Domino TZ-style twin cable to a pair of Delorto PHB 40s.

Clutch cable, that ain't going in there, no way. Either I make another one or, if I'm very lucky, Mode Performance may have them in stock (first phone call of tomorrow morning). I can guess which way it's going to go...:blagblah

Yes but it's the little fiddly jobs that come at the end of the project, you're on the home straight! ;)

These are the guys I have used for years and very knowledgeable http://www.venhill.co.uk/ They will do a custom service & can build from patterns or drawings.
 
I've had a couple of suggestions for cables, thanks. The new clutch cable is actually a Venhill one and seems to be very decent quality. I'll measure up what I actually need and phone around.

No response from Mode Performance, the Brembo people, about a clutch cable adjuster to fit their lever. The one they provide has an 8mm counterbore whilst the Venhill clutch cable needs an 11mm one (like the standard bike). Can't bore the original out as there isn't enough meat on it. I think I'm going to cut the original counter bored bit off, make an appropriate sized sleeve and TIG it on there. You'd think there'd be different sizes available. I bet I wouldn't have had this trouble with ISR levers :green gri

Got a couple of days of work on 'Doc Martin' this week and again next week. Hopefully that'll give sufficient time for a couple of the bits I'm waiting for to be finished.

Anyone tried the DIY Zinc passivate kits? I was thinking of trying the Gateros Plating one...

Someone on here was selling one the other day; a search may lead to user experience ;)

Edit: User name of Mech
 
Had Venhill made for my 2 guzzi ' s.
Bought spares as well but never needed...
highly recommended. ..
 
cables

another :thumb2 for Venhill

They will make whatever length you want, with whatever fittings on the end you want.

Give them a call and discuss your problems, and Im sure they will be able to assist.


Keep on with the build (and the updates) as I can't wait to see the finished item, and maybe a video of it running.

Back on it...

Sorry for the lack of progress, 'Doc Martin' took a bit more time than they expected. However my lovely wife is off camping with her mates this weekend and I'm not invited - well, someone has to babysit the dogs. Anyway it'll be dog-walking and bike building for me.

So, to the pic, the metal bits are the driveshaft coupling but slightly modified (it was a prototype!) and the the carrier that'll mount the rear wheel on the wheel building jig to true and tension it (at long last!). The white bucket is a Zinc Passivate plating kit, from Gatero Plating, with which I intend to refinish some of the odd steel bits.

The unfamiliar stainless steel tooling on the 40" Snap-On roll can in the background? Well I retired that box and I use it as a kitchen cabinet these days. :D
