Almost got my second trolley finished. It's unbelievable how much
time and work goes into a little thing like this. I think the hardest
part is making the rubber block. Have you ever tried cutting solid
3" rubber before? I'm ready for spring.

Metal fabrication has always amazed me at how long it takes and what little you have to show for your time sometimes.  Chainsaws cut rubber very quick and easy if you've never tried it.  Gotta make sure the rubber is held down pretty good though.  The only other way I've found is to melt/burn through it.  Outside of course!  :D
I wonder if a tire siper would work as a cutter if you take multiple passes with it?

I bought a used forklift real cheap because the seller said the axles
was bent... The axles was not bent but the tires was egg shaped.
I jacked up the forklift and fired it up. I put it in gear and let the
wheels spin. Then I took the chain saw to it. They cleaned up real
good. To cut my zip-line blocks I used a 6" cut-off wheel in a side
grinder. Sure made some smoke and now my coat stinks.

Yeah, I've cut rubber that way too when I had to.  Not by choice, though.  I remember the smoke and stench.  That crap will almost take your breath away.  Not to mention the little pieces of molten rubber flinging all over the place!

Yea I learned a new word today. When you cut the rubber with a
cut off wheel the rubber melts and stays melted. So I googled why.
It's called reversion. It's when the rubber breaks down. I do know
once you get that stuff on your hands it's just about impossible to
get it back off. Many years ago I got two forklift tires that was never
put into a circle. They was eight feet long four inch thick strips of
solid rubber. They sure have come in handy over the years for
different projects.

Reversion, huh?  Interesting.  I learned my thing for today!  I would have liked to have one of those strips of rubber.  So far I've gotten along with cow mats and cut up tires.  Sometimes bolted, screwed or riveted together for thickness.  I used to use hockey pucks for body lift discs in my truck.  Super hard rubber and cheap.  Used to be a dollar a piece for used ones at the sports shops.  Each one is an inch thick and I think 3" across.  Matches up perfect with the old style body mounts.

The only difference between the two besides the color is that the
grove in the rubber brake is not as deep and I think it works better.
I will be making a new rubber block for the first one.
