| 20/20S This
is going to be pretty much a clone of the 20/20Hi
but I'm using some 1" square instead. No particular reason for it,
I just have some kicking around and thought I'd use it up. So, the "S"
just stands for "smaller" tubing. I'm in the process of making
a new jig so that I can make my (hopefully) final standard version of the steering
arms that are tilted down parallel to the front section of the frame rails. If
plans go to spec, it should put the tie-rod in a much better location where it
will be better protected and also ease the fabrication process of the trikes to
come. We shall see :)
| 3 Dec 2007 After
about 10 hours of work, the trike has progressed to what is on the right. As
usual, the actual fabrication process of the big pieces is fairly fast, but the
"cosmetic" tweaking and small part fabrication like seat rails and tabs
take the lion's share of the time. Pardon the blurry picture, I blame .
. . the camera. The dropouts and rear rack tabs are also mounted but out
of the picture frame. I got the kingpins and axle tubes welded up and will
use my new jig to fabricate the steering arms tomorrow night. I need to
get the wheels on it so I can fine tune the BB height relative to the ground.
Once the kingpins are on, I can make the last couple frame pieces that the
boom attaches to, and then make the boom mounting tabs for the cross member. |

Apr 2008 Many moons since the trike
was actually done, but I was just lacking motivation to do updates, until now.
I had a fair number of extra pictures taken, but not sure where they are
now. I did manage to find one of the triek fully mocked up prior to powder
coating. I have no idea what all the junk on the lens was from though. A
photographer I am not. I used the "new"
seat again with the modified base-back angle of 45º vs the old 60º.
Much nicer and more comfortable to sit on. The only major difference
with this one was to come back and down off the axle tubes at a 15º angle
with the steering arms so that the tie rod would (hopefully) slide through the
frame and completely avoid the chain. Which it did. I got the lion's share
of the new steering arm jig done, but still not finalized so I did this one un-jigged.
It still worked out fine though. Final
pictures are below after it got a nice candy apple red powder coat job. I
mounted an aluminum rack to the rear using 1" x .125" aluminum flat
stock to support the front, while the happy new owner added a fender, some lights
and a speedo. The red and all the black looks really amazing in the flesh,
and it is a sweet little trike. One more 'bent out there. It's a good
thing. :) | | | |
