Hi Dave, how did you get on with measuring?
Hi Bjorn,
apologies for the delay. Here are a couple of photos and dimensions. If you need anything else, just let me know.
The length of the belt measured on the inside smooth surface is 428 mm. It is 31.6 mm wide.
The thickness of the belt at the thickest part (to the tops of the raised areas/finger grips) is 1.98mm. The actual raised 'finger grips' are 27.6mm total width across the main band and the plain areas at the edges of the main band are 2.0mm wide. Each of the raised bands are 2.14 mm thick.
For the drive wheels, they are 35.20 mm diameter at the largest point (they are slightly convex along the central seam line). They are 34.95 diameter at the outer edges. They are 27.90 mm wide. The axle is 6.85 mm diameter which narrows to 4.48 mm diameter. The widest part of the axle is 2.54 mm in length from the wheel centre on both sides and the thinner axle which continues is 4.62 mm long to the tip of a point on the shortest length and the opposite side is 13.68 mm long which is then split to accept the brass collar. I may have to draw this and include the dimensions as it's confusing to me and I've done the measuring!
Hope that helps. If you need anything more, just let me know.
Dave.
