Hey Guys,

Ive done a fairly major update to my webpage. Ive posted all the pics
from the build of my new unicycle, and pics of the jigs I used to build
the frame. All the pics are linked to an enlargement and a (hopefully)
useful explanation.

you will find it at

www.geocities.com/unicyclefrenzy

the projectmuni page is new, and the projectFB and minigiraffe pages
have been updated.

Leo-

Clean, simple, strong looking frame. Nice welds. There is some chemical
process to get rid of the discoloration isn't there?

On the photo of the bearing clamp, okebearingclose.jpg, the clamp looks
overtightened. Is there a big gap on the other side that I can't see?
Why titanium...just to be *** or did you have the hardware
available?

Is the four cross spoke pattern stronger for torque and springier for
jumping than the more standard three cross?

Your jig looks very well engineered and easy to use. Can you knock these
frames off quickly?

Unfortunately, I couldnt get the EXCACT tube for the seattube. I wound
up having to use 1"OD x .052" instead of .058".  the .052" material
gives a clearance of .019" to the 7/8"OD seatpost. thats why I had to
cut a bigger slot in the seattube and squeeze it up. In practise, it
hasnt yet caused me any problems, it dosent move or spin. If I had the
choice, Id go for the .058, but you cant have everything!

The titanium bolts just happened to be there, and they were the right
size. Plus, I just HAD to have something titanium on it!

From what I was told, the 4 cross is supposedly stronger and holds true
for longer. Due to the small clearance, I thought that strong is good.
Its the same weight and amount of spokes regardless.

The Jig is pretty simple. Took me about 2 hours to make it. I can create
a frome from scratch in about 2 hours, quicker if Im doing more than one
at a time. The only problem with it is time at the welders. The welders
charge a bomb, and they cant seem to grasp the fact that I need it to be
perfectly straight. I thought about the commercial viability of making
more, but unless I buy a TIG welder, its not worth it.

Thanks for your comments!

Leo

I dont know of any other way, but it dosent matter, I quite like the

Great write up!   Thanx for shairing!

As for discolouration:   heat colouring is just pritty oxidization- fine
sanding/buffing should make it vanish, as it is only on the surface.

I think I might have some questions about the project- once I wake up
:)

Thanks. Now that I have woken up, Ive been through the site and
corrected MANY mistakes and typos. The only REALLY bad one was the
weight. That has been rectified.

I kinda like the colour. I might find out how much gold chrome plating
costs..... like the finish on the frames of Ducati motorcycles.
yummmmmmmm.........

Often a coat of Copper or Nickel is put down before the crome... just
the copper layer would look great!   Of coarse, you'd have to wax it...
