My next build is well under way…
Almost a rolling chassis, just gotta fit rear springage and make yokes…luvlee.
ye its alright…
looking like a great start mate keep us updated! :)
Aye - tis looking pretty. The lines and grooves work well with tank and tail unit. Feeling that rim tape to.
Looking good:cool:
I recon I’d bend that sub frame though;)
Looking good Fella, Lurve slabbies. The Tank shape is pure sex
Here’s a pic of my old slab, wish I still had it :crying:
cant wait to see what comes of it.
The story so far…Made up a mount for the dogbone, this had to be moved to get the rising rate linkage in the correct position. So i cut off all the old crap from the lower frame crossrail and mounted thus…
The sides of the mount need to be welded in, then the rail tidied up with a plate. All mounted up, looks like this…
Onto the top mount then, due to the position of the shock top eye, a link needs to be made to get the mount in the right place and looking tidy.
I used a box to link the top cross brace to the original mount rail. The open side of the box will be closed in with a plate with an adjustable set-up for ride height. The top rail will also accomadate the rear tank mounting and battery box. Then it’s all closed in to tie it all together and make the open sides of the frame nice and clean…
All of the open cast parts will be closed in and blended as above.
Currently working on the adjustable shock mount so i can get the plate welded onto the frame, then it’s sitting on it’s own two wheels.
Got a nice piece of aluminium on its way to me for work to start on the lower yoke…50mm thick should do it.
A tidy bit of engineering, do you carve up the billet for the yokes yourself?
I was lucky enough to come across some 6082 T6 in 100x50mm…cut to lengths of approx 335mm on ‘that’ site. Which is just big enough to fit the shape in…think i may be buying some more for future jobs.:hehe:
All i have to do is mark it all out, bore the holes, then bandsaw it out to shape…no CNC over here!..just good old files and elbow grease.:w00t:
Not too sure about the top yoke yet, as i dont have the bike sitting at the correct ride height yet to establish if i need to drop the yoke…so may be a little extra work with the top one.
I think overall, my only concern is drilling the clamp holes in at an angle into the block, i’ll prob need to machine the holes with a mill cutter to get it flat before drilling…these will be the countersinks for the allen heads anyway. 50mm thick should allow me 4 or 5 bolt clamping, depending on thread size…M8 should do.
Looking good Stig, very tidy
Keep the pic’s coming of the progress on your yokes
A bit slow on progress at the moment Terry…got a V-Max engine to rebuild…poor bugger ran it dry and anihilated the crank…and it would be an easy out to get a new lump except this one is special inside.
Trying to fit mine in whenever i can, got a few loose ends to tie up with the frame before i move on to the yokes…but i’ll keep you posted.
just saw the last one featured…cant wait for this one!
Thankyou kindly sir!
Ok…next bit then…
At long last it’s sitting un-aided. Got the top mount more or less set up, a few bits to do, but in the main the bike is on wheels and suspended.
The adjustable part is all stainless and the fork can turn on the bolt so ride height is adjustable without any need to disconnect the shock and simply slacken lock bolts and turn height bolt. I may get some pics up of this bit when i finish it off.
I started the mount by machining a slot in the plate…dreadful pic!
Then a plate goes in the slot at the correct orientaion…
Then drill and tap the bolt hole and weld the two pieces together…
The whole lot then goes to the frame…
Finally, weld the assembly to the frame and add the two gussets…
We’ve been bouncing up and down on it, trying to break it! All that’s left is finalise welding and tidy up…including the bolt/fork assembly and polish the stainless components.
I can now get going on the yokes…joy!
nice work man!!
looks long whats the wheel base work out at?
I haven’t measured it actually…i don’t reckon it’s gonna be much different to the norm, it looks long without bodywork i think.
But i’ll measure it anyway.
Wheelbase is 151cm.
Doesn’t look so long now…and the subframe is allready strong enough to take my weight without the extra pieces in yet!
Update on the latest. My first attempt at making my own yokes! I’ve bored the three main holes and can cut out the basic shape.
I’m very pleased with the result so far…the stem isn’t pressed in yet…it’s a lovely fit and the yokes are really snug on the legs, so rough assembly to check it’s all basically straight, thus… ;D
I’ll get the lower yoke done and bolted on then figure out how i’ll drop the top yoke and get going on that.Rolling chassis is near completion!
Mate, that is looking very nice indeed keep us posted
dam ! what did you cut the holes with?
exciting stuff mate
I have an 80 year old lathe, but it’s pretty versatile.
Removed the cross slide and bolted an angle plate to the carriage. I then bolted angle iron to the plate to rest the slab on and clamped it to the angle plate. Then it’s just a matter of drilling out and finishing with a hole boring tool mounted in the chuck. So long as everything is squared up right in the set-up, all the holes should be true with each other and perpendicular to the plane.
Next i’ll cut the shape out, drill and tap the clamp holes and cut the split.
I’ve checked all the measurements and the holes are where they’re supposed to be but i won’t be 100% satisfied until i finish them and can clamp it up tight to check alignment.
