[QUOTEGoing hard tail is likely to cost more than I'm willing to pay to make the mods required, so the idea will possibly remain just that.
But two sets of springs is silly. What to do? What to do?
If going hard tail is too expensive, the mods necessary to switch to a single spring system may be astronomical. Save your money and learn to live with what you have.[/QUOTE]
Perhaps I misunderstand you/ the correct terminology - to my knowledge (which is very little when it comes to cruiser style bikes) a hardtail is a bike which lacks rear suspension which is made up by springs in the seat - no?
Either way, the seat is on now after a marathon session in the workshop - thanks a lot to J the mechanic who worked out the puzzle. The problems was the distance between the bolts in the seat (which were fixed) - it was too wide for them to be attached to the frame, so the solution was a bar to which yet other bolts were welded. These latter bolts sit in and are tightened to small diameters of pipe which have been welded onto the chassis. I haven't got photos of everything, but will do so in time as I come to whip the seat off and paint the weld (probably at the weekend).
The springs looks **** with the seat fastened as it is, so no hardtail or whatever ATM.
Luckily we had some help from the garage kittens Bubble & Squeak
Riding it home was interesting, a bit 'tingly' if you know what I mean
