Finishing motor arms.
Second idea. Decided to space the hoop mounts out instead of cutting the bolts.
The bolts fit really tight through these so I drilled them out with a 1/8" bit. Still plenty snug. The bolt heads still fit quite tight into the recesses
Lining up the arm hinges in pairs.
The nuts are metric but a 9/32" wrench worked nice. Tighten, then back out 1/4 turn or so.
An evening’s labour. Getting a blister from the screwdriver handle. :-7
Note that I’ve not added all of the hoop mount blocks. The kit was short on the bolts for them. I’ll have to go by a handful.
