Dogbytes' R80 ST project

Bits for sale

I'm just about to put some parts in the for sale section. All from the R80 ST. Exhaust collector, sound but needs a polish - which I'll do if I have time. Silencer, same condition. Rear subframe (too wide for the race seat) bead-blasted and ready for painting. Collector £100, silencer £125, subframe - offers. All plus p&p

Loads of other stuff on request, bodywork, indicators, electrics, etc.

Merry Christmas:)
 
More frame work...

I'm beginning to think I'd have been better off making one. Or maybe buying one!

Anyway, these are the diagonal braces awaiting welding.

Happy New Year, by the way! :)

Dogbytes lives not far from me so we have already shared some supplier info so hopefully that'll speed the background research and get us moving faster ...:Aurelius

I think we have a winner!
Come on dogs ..... It's been over two years now and you're still welding gussets to the frame!
Me thinks there needs to be a collective UKGSER kick up the arse!!

Keep going fella :thumb

You haven't got a winner quite yet - Pete's just unfinished itself!

Just about to fire up the TIG to put those cross-braces in.

:)
 
Tomorrow I can chop out the bottom rails and start making the joints.

Back to the lathe next

Got to make four pairs of little joint thingies to fasten it back together.

Meanwhile, in another part of the forest, the K1200S is awaiting a new front brake master cylinder. £300. Great bike, crap braking system. No wonder they went to a different one in 2007.
 
Warning!

I feel I should just point out - lest anyone else be so bored that they start doing the same thing.

If you put the diagonal braces in this position with the engine raised, even if it is moved forward, you WILL NOT be able to fit a standard engine into the frame. The oil filler has to be moved and a little clearance 'created' around the flywheel/clutch housing. (ie I get to cut more bits off!)

As with everything on this frame (not least the timescale before anyone else brings the subject up!) I want to do it how I want it rather than for the sake of convenience. It's more a case of what is possible than what is necessary - or even sensible.

The engine will be able to be removed like this...

The weekend arrived early!

Got to have a day off tomorrow but I picked up the steel to make the joints this afternoon. I'll be back I the workshop on Saturday and, if I get a good, solid days work in in, I'll be able to get them finished. I'm looking forward to this bit - it takes me back to 1970's Bimota frames and my old Moto Guzzi Le Mans Mk 1 PR. :)
 
Joints

Didn't get them finished - but I got them started!

These will be the four pairs of fittings which will hold the lower frame rails in. I've turned the outside diameters of them to fit inside the cut ends of the frame tubes. I also bored them to reduce the weight. Actually I bored them with a 10 degree taper so that I could combine strength with the lightness. No-one will ever know except me... And you, of course :)

Got to machine the flats on them now, then drill and tap the various holes. Then I can weld them in.

So how do you plan to slide the engine section out of the main frame?

It drops out of the bottom - hence the removable frame rails. Actually one removable frame rail is sufficient but I wanted to be able to lift the bike off the top.
 
Hmmm, I also can't see how the bottom tubes plus engine will slide out as the bottom tubes splay outwards. If you try to slide the lot forwards, the opposite joints prevent movement and vice versa. I look forward to the next instalment.

It's very simple and the way the tubes splay have no influence on anything. Should be done this week, all will be revealed! :)

I'm guessing that the inserts slide back out of the way internally allowing the tubes to be released?
