So.. I spent a good part of Easter Sunday making the 8 wheels for my monster.
First, I traced the outer diameter and the inner hub diameter onto thick stock for cutting purposes, 2 pieces per tire. Because of the sandwich-type construction of these tires, I had to remove the center of each slab for hub clearance, otherwise I'd have done it much more simply.
then I tediously drilled out the center sections so they could be removed- I wish there was an easier method than this! After I got all that sorted, I just glued the slabs to the tire halves and began work on the hubs themselves. (I did keep all the little starburst shapes from the centers- those will become sunflowers at a later date!!)
Since widening the tires affects the location of the mounting hubs and tire offset, I had to make some corrections to the hubs. A small length of flexible rod glued into place is the fix here... these are hidden inside so there's no worries on the sloppy appearance.
After everything had some time to cure, I went back with a Dremel power tool and used a coarse grit sanding drum to grind off all the excess white plastic, flatten the tire's profile and generally rough them up. A follow-on sanding with a finer grit sandpaper and then a wash with MEK to soften and blend grind/cut marks was all thook to finish that part off. At some point in here I cut grooves into the tires- that was boring.
I went on to add a 1/16" strip of thin plastic stock to the rim to act as a protective measure and that's that for the wheels (and a Sunday afternoon). I need to biuld 2 more to hang as spares.
Stay tuned for the next unscheduled installment.
