Progress on wheel tread

It turns out that some of the holes did not get drilled exactly where needed - so needed some additional adjustment with drills - this isn't an exact science.

The holes on some of the treads were too near the sides and other holes weren't inline perpendicular to the sides making screwing in the bolts difficult.

Partially this is due to the first tread strip having some inaccuracy at one end of the strip where the holes were offset to one side by some millimeters.

It's also possible/likely that the original hole markings, which were made by a thumbtack through the metal wheel into the back of tread held on with a strap - so many of these tread holes probably weren't exactly in the center of the wheel hole.

Some hints:

• before drilling holes in the tread, measure and mark the hole spacing and make sure the holes are in-line perpendicular to the tread/wheel
• try to screw in bolts on the gear side of the wheel first before screwing in bolts on the none-gear side of the wheel, because:
  • these threaded holes are only half-holes threaded on one side of the hole with the other side being open space
  • this means the bolts are likely to go into the gear-side holes at an angle and may wedge themselves into or strip the wheel hold

We should consider if these treads or something similar could be attached to the metal wheels with industrial double-sided tape and/or velcro with industrial adhesive backing
