Cutting the frame and fitting the seat unit.

     Posting today after a long while. Have had a few things going on, so my bike has taken the hit. Now settled at my new home.
     I removed the handle bares and steering from the frame. The bearings are worn and will need replacing, it was very notchy.
     The seat unit decision took a lot of time and thought, Possibly too much thinking, sometimes with a PBR in hand. Eventually, after much web browsing, i settled with Dime City Cycles, and browsed the selection. I settled on the THRUXTON Fibre Glass seat pan and the all in one PAD that goes with it. It is the right length and width, but the frame will need a trim.....out with the angle grinder.
     Measuring 6 times, i cut only 4, below are the pictures for the before and after of the trimming. As you can see from the marked before photo, there was about 3lbs of metal to trim:






















The resulting cuts and a little grinding left these parts in a zip-lock, just in case... The rubber bushing may be used to support / cushion the seat unit.


     So, the frame is cut:

  

     It took about an hour of cutting and shaping to get the fit, but as you can see, not too bad. My only bug bear is the seat sitting a little too high on the frame. If i want it lower there are a couple more square lugs to cut off, the problem being is that:

     If I lower the seat unit any more i will loos the lines between unit and tank, however, it will cover a little more of the frame. I think the line is more important, but will mull it over. You can see the initial results below:




     The seat pan fits nicely, the pad is about an inch short, but i intend to have it upholstered in leather with a diamond pattern in the stitching, will use this opportunity to lengthen the pad a little to fit it a plush fit.
     So, that's it for today, juices have been flowed and interest reignited for my project. Now to look at the foot pg requirements, a little frame trimming and dressing before the powder coating. Gloss black is the decision.
