    Ill be making some solid brackets out of 15mm aluminium.

    The brakes do indeed have separate ABS chambers but can be easily sorted with some strategic drilling :thumbup: ......ive used them in a past project (post#127 here): http://www.mig-welding.co.uk/forum/...g-wreck-rescued-from-the-spiders.44354/page-7

    Have been managing to get the odd hour or two on the bike over the Xmas holidays. I've been accumulating a few swing arms in my quest to convert this thing to twin shock and get away from that drag bike look using the original setup. After trying a few different ones, I've settled on an old CB350. So first things first i need to get a rough idea if a) its going to fit and b) i can get the wheel centralised and lining up at the crucial points.

    Next job is to shorten the main swing arm spindle. It was tough as old boots......several tungsten tips later its all good :doh:

    Then onto making the swing arm a bit narrower to fit in the frame.

    Next up is to temporarily refit the steel bushes after reaming, back into the swing arm tube. I'll be changing these to some sort of bronze on final assembly.

    Time to see if it all fits and lines up........:whistle:

    I think the proportions are much better with the shorter arm, and the round section material more in keeping with the rest of the frame.

    Managed to score a nice set of used Ohlins shocks............but all that glisters is not gold:doh:....they are a bit worse for wear, but with few hours elbow grease should clean up ok? First things first was to take the springs off so I could confirm they were actually damping !!..........Fabricated a small set of puller out of what was lying around.
    All good with no leaks or any mechanical damage. The reservoir on one shock looks worse than what it is. It had a throw away bush where the spring rubs on it, this had cracked allowing rust to eat away over the years ;)....i'll sort that out, for the price I cant complain...

    Time to get some of the other bits precariously balanced on the frame, just to see what it will all come together like........was running out of G-clamps at one point :D:D:D

    Next up is to mount the tank and fabricate the seat hoop. Before this takes place there were a few "lumps" under the powercoat where I'd be welding in some brackets etc which needed further investigation!!!

    So out with the wire brush and flap wheel.....................:whistle:

    believe it or not this bike, as I bought it was "only needing a few bits to finish" type of project. Purchased from a supposedly reputable mechanic who was running his own business and "had worked with a lot of the top British riders" in his past :laughing::laughing::laughing::laughing:

    say no more :vsad:

    Looks like a few bracket removal jobs went horribly wrong in the past :doh:

    Time to get the TIG out methinks :welder:

    That's probably the reason he worked with a lot of top british riders, once they saw the quality of his work, they got rid of him :laughing:

    maybe worth stripping the rest of the frame before you start to see how many other hidden "repairs" there are.

    I am always amazed by how thin the tube in bike frames are. What are steel you going to patch it with @lchris21 ?

    Going to use a bit of the original subframe I cut off. Need to squash it a bit as the damaged section is slightly oval....

    Some people made some very fast Sound Of Singles racers out of them in the 90's! Mmm Tigcraft, Spondon, Hijera, Over Racing.......
    I need to dig out my Performace Bike mag with the article on them all. :laughing:

    Here we are! Took some rooting around to find the magizine but here are a few poor photos of the articles.
    STR 750 DR engine in a nice frame.
    Tigcraft one with dyno chart.
    And my favourite John Laker's Yamaha SRX600, an almost stock bike that he raced and made most of the others on very trick bikes look silly!
    If you can read it I like the bit about him porting the head with a dentist's drill! :o

    On a side note, and quick update on the scabby "de-lugging" job undertaken by the previous owner. I went to town a bit and ground back all the suspect areas, filled in where needed and re-dressed. The frame looks to be in decent condition with a no obvious major damage which was my main concern. Abandoned the TIG and got the big guns out with the mig :welder:.....I've sorted the suspect filled holes and bad de-lug jobs. Took the opportunity to remove a few extra lugs while I was at it. I'm confident its not going to collapse underneath me and spit me into a hedge now :rolleyes:
