Okay, here goes, Carl these are the measurements, some photos to come also.
Vital measurements:
total length from centre of pivot bolt to foot disc on the end of the stand is 16"
from the disc on the foot to the loop for the spring is 9"
from the foot to the retaining band peg (for the rubber band) is 10"
angle of the foot disc is about 30 degrees off straight, and should be determined last of all - make the whole stand leg with an extra 1/2" length, fit it up, stand the bike on it and then scribe the angle 1/4 inch above ground level and you will have it right.
pivot piece - use as heavier steel as you can, start with 10mm or 12 mm plate, and shape it initially with a hacksaw or angle grinder, then shape it finely. - make sure you have enough to extend into the tube you use for the leg at least 2 - 3" (this is where i went wrong the first time).
when you fit it in the tube of the leg, make it as tight as practical.
also nothch the tube of the leg to accept the pivot piece, it will add to the strength of the stand.
have it all welded together, and consider an extra gussett to limit where the leg swings forward to when it is down.
use some spring steel wire (match the guage of the loop on the frame), or alternatively something that will not stretch and fatigue easily for the loop for the spring. - i drilled mine through the leg and welded it from the back side as well.
use a piece of thin shaft for the rubber strap peg - drill through and weld from the opposide side as well.
prime and paint a couple of coats.
there you go!new stand, cheap as shyte. and looks just as good
