On the first Python front end I slit a pair of round tubes down the middle and welded them to drop out extenders.
Whilst it worked and umpteen years latter is is still being ridden it created a couple of problems , due to being
slit down the middle the tubing on the inside interfered with both the brake disk and the cassette.
So I though being smart [ ok bare with me ] as this tubing is rectangular I can slit it neatly on one of the vertical walls and this will give me the same 4 welds per tube but not the interference ?
On reflection are the welds on the inside a waste of time as all the loads are being taken on the narrow piece of tubing on the inside face at the end of the slot ?
Maybe it would be better just to lay the tubing on and do welds in the V's where it meets the long sides ?
Or ...
