Building a tow behind mixer is almost never done with "new" parts. To
my knowledge there is not anybody building and selling "new" Tow
Mixers.
There are often used ones for sale.
Most tow mixers are built by the people that use them. They tend to
build them from salvaged parts for the axle and frame. The tank and
maybe the trailer hitch are about the only significant new parts used.
From time to time an experienced papercrete builder may custom build a
mixer for someone upon request, but I think this is still fairly rare.
If you're spending more than a couple hundred to build your own Tow
Mixer, you're probably spending too much.
If you're paying someone to build it for you, expect to pay more, but
it need not be extravagant.
With intelligent scavaging for parts, no problems finding the tools and
skills needed (welder). A mixer can be constructed in a full weekend
of work, or a couple partial weekends. Often it can take longer, but
usually the extra time results from missing parts, getting that extra
set of hands at key moments, waiting for your welder friend to show up,
etc. If everything and everyone is ready to go, it can happy pretty
fast.
While I'm often the first person to get all technical and scientific
about things, papercrete is hardly complicated. That's part of its
beauty. The materials and equipment to make it and work with it are
within reach of anyone with the physical strength and stamina for most
any type of construction.
It's fun to discuss fancy tools, pumps, grinders and such. The fancy
more expensive tools might make a lot of sense in some situations,
especially if someone is going to be a contrator or build a
particularly large structure. I don't want to dampen these bigger
vision discussions in any way. Let's keep talking about all different
aspects, but let's also not allow big ideas to frighten anyone away
from more common or humble alternatives if those are what make sense
for their particular situation.
There is plenty of room available for everyone to mix papercrete and
post in Papercreters about it in a wide variety of ways.
