no beer and deadlines sounds horrible, so we'll do beer and no deadlines. i keep
going back and forth on materials but one of my buddies has a shit ton of uni-strut so
maybe we should bolt one together to start the experiment. as far as open sourcing,
we'll just share our shop drawings which will be pretty simple. full disclosure - i
would like to do a production run of these, sell most of them, and divvy up the net
revenue (or just trailers) between people who help.

Seriously though, I'm interested but I'm also a bit overloaded on projects. I
could do it on a saturday or sunday every now and again though. Especially if there's
beer and no deadlines.

OK looks like a few folks still on here. Scheming on a family bike trailers,
starting with 1) flatbed, then moving on to 2) pedicab and 3) enclosed / RV variants.
2'x4' and 4'x8' bed sizes.
As it stands, the MacArthur shop has undergone a
purge and does not want a bunch of people showing up randomly to work on things, so for
now we still need to find a spot to build. Matt has tentatively offered to help build a
prototype in his basement (!!!) pending resolution of tool and material details.
I circulated one design using 1-1/2" x
1/8" angle steel which would allow us to machine dropouts right into the frame, but
is way too heavy all said. The next oscillation was for prototype was based on 1" x
0.20" square tube available quick and dirty at home depot - super lightweight but not
nearly as strong, possibly not strong enough for proper cargo moving without a plywood
deck. We could play up the lightweight thing, with a deck of 1" styrofoam sandwiched
between sheets of 1/4" plywood, framed at the perimeter with 1" square tube.
The dropouts would have to be either plate or angle welded or brazed to the tube
sections. I've been paying attention to alot of bike trailers that have been brought
around and this seems like the most sensible detail despite requiring a bit of extra
welding. for pedicab and enclosed applications, it might make sense to use a plate that
extends above and below the frame tube, to act as dropout below and above a tab for
bolting on seats or wall fra
ming.
thoughts?
cheers,
hol
