Jon. What is the pipe size and thickness used on the Rd frame, what size pipe did you use for your strengthening sections. If your modding things like rear mater cylinder brackets would you use 3mm plate or more...
Well as usual I have been flitting between projects.
My Kenny Roberts YPVS has been painted, and just needs a few more panels cutting back.
Last weekend I've been working on my latest LC hybrid. A while ago I asked Nigel at NK racing for a quote to modify my FZR arm to fit an LC. All was okay until I mentioned my frame was spread, to which I got a reply he couldn't do it as his jig was for a standard LC. I'm not too surprised at this, but a little surprised he was not prepared to take it on?
Anyway, I thought 'Oh well, I'll have to arrange it myself'.
I spoke to my local welder Jason about doing this and he said he'd do it. I made a jig from the LC arm, and drew up some brackets in CAD.
Anyway, the brackets were cut and i arrived with my jig on Saturday. Unfortunately I'd somehow managed to mess up on the bracket height so it was out!
Jason was so understanding about this and offered to adjust them in the afternoon, then weld them Sunday.
He even offered to try and teach me to aluminium weld, so in his words 'you can stop pestering me to weld something, you can can come and use my kit and do it yourself!'.
I had a quick go, and within 20 minutes I had something that would probably hold 2 bits of metal together, but didn't look too good. It's totally differnt to MIG. I'll be back to see if I can master it?
Anyway, he made it look so easy as I watched him do my swingarm. In fact to say I was in awe of his co-ordination is an understatement.
I'd made a jig to keep everything square:
It was really quite complex and difficult to describe how he suggested doing it but ill try. The vertical plates have ears which fit into the bottom plate. These were welded underneath first. Next the vertical plates were welded with a root weld. Then gone over the top to build it up. Next the assembly was set up in the jig and tack welded to the arm. After this the jig was removed and a root weld either side of the plate. then twp lines of weld over the top.
Blimey, reading through this thread makes me feel utterly insignificant! I have a question of you who know about swing arms / shocks: I have a standard 81 350LC which I'm overhauling. I'm at changing the swing arm bushes but, when I removed the sleeve from the tube there didn't seem to be any bushes! The frame has been powder-coated by the previous owner and I wonder if the bushes weren't removed and the 'hat' part of the bushes has been effectively incorporated into the tube and over-powdered then baked. When I feel inside the tube, about half an index finger in, I feel a definite ridge / lip - but it's the same diameter as the tube. Help!
