    The common approach is to weld in a horizontal loop that arched te rear tail section profile

    Yes that looks like the way to go. I will probably replace the whole horizontal member under the seat at the same time, and potentially the diagonals to get really some clean lines. Will also need a new tab to pick up the shocks which will be pivoting further inwards. If I'm lucky I'll get away with the length I have already but time will tell....

    A lot of nothing, and then a bit of something, as a friend and I set to work on fabricating the new rear frame. A few pics of the process below. Essentially started out with some drawings, then some metal bending, then chopping the backside of my bike off. Aiming to attach new frame in the next few days hopefully.

    Hoop looks great in the last shot, how did you do the bend?

    What year is this bike? If it was stated already, I missed it. I like the shape and overall design of the tank

    CB200 Cafe Racer

    I can't remember off my head, roughly 74-76 though.

    Got some more work done getting the subframe tacked in place today and starting to work on the diagonals. Cut the rest of the original rear off too, needs capped off.

    Need to do a little work on the underside of the tank to get it to drop down over the frame and sit in line with the sub frame. Temporary tube/lugs on the frame to ensure levelling the subframe.

    I had a pipe bending store do the bends from some templates I made, as I don't have any access to bending equipment, or in fact the know how to do it myself. However they made the single hoop from 3 parts. I later had the two sections nearest the tank made and with a friend welded the two together (last set of pics above).

    Some pics from today:

    Is it a polyester type stuff that I've seen in the likes of Halfords? Ideally looking for UK buyable products for this

    Also, is it a good idea to get the tank blasted?
    You don't really need to get the tank blasted, it look fine like it is now.

    As for the filler for the top of the tank, it's a good idea to used reinforce fiberglass filer. It is less prone to crack. Something like this one:
    Bondo Glass Reinforced Filler, 00277, 1.37 lbs, 12 per case 00277: Advance Auto Parts

    And you use a good high build primer surfacer like the Omni MP282 or PPG K36.
