ah! that crown looks dangerous, you should consider plastic caps or
something.

Evan, for thin to thick welds, concentrate the heat on the thick metal
by starting the spark on the thick metal and aiming it at it. Also, try
to make the thick metal be above hte thin metal, so the heat gets
concentrated on the thick instead of the thin. Noticing the heat marks
on the seattube, it looks like you applied heat for way too long. Try
starting with a higher heat and getting the puddle to start
immediately. The faster you get the puddle started, the fewer heat
marks you'll have.

Otherwise, it looks like a good frame. Two things to keep in mind: When
you're done, hit the welds and the areas around them with a wirewheel,
It'll make them look lots better. Be sure to wear eye protection. Also,
chrome is very unhealthy to inhale. Next time you need to weld to
chrome parts (the bearing caps), try filing or grinding the chrome off
(wear a good dust mask, and make sure it fits), and I've also heard
drinking milk beforehand is good. I don't know if the latter is just an
old welders' tale.

In my opinion, the frame looks like it might be too weak (judged on the
size of metal involved) and might not stand up to some heavy trials
abuse. I think that having the frame arms drilled out is a good idea,
for a bit of weight saving, however I think the crown could have been
slightly better designed, and perhaps less hurtful 😉

A few revisions and you could be onto a winner there

Evan said he will probably make me a new frame with a different kind of
crown. It would probably be out of a different kind of metal too
because he complained alot about welding it 🙂 I think this one was
kind of a test because it was his first frame.

maybe it's because the metal is so skinny in comparison?

It looks nice, evan... but seriously do something about those ends
before you seriously land on them.

The crown is spencer problem, not mine🙂

Pft, thanks. I already have like a 3 inch cut on my leg from trying
hickflips...

And the tire is just a normal luna.

For the crown, try grinding 45 degree miters into the edges (shouldn't
change its strength), so that the miters meet the forkleg right at the
weld. Then, weld in some very light guage steel sheet over the holes.
Tack at each corner and then weld opposite sides, don't just go around
in a circle. This should help the crown be at least a bit more knee
friendly. Next time try shaping that area to be a bit rounder. Either
hammer in some more antural shaper or just design it to be lower
profile.

Nice going!

The top tube would be be hugely stronger if you closed the open ends
with steel (not too light) welded all the way around. Open tubes like
that distort and twist much more easily. Perhaps with a slant like
gerble suggested?

I dont get why people complain about the strenght of the frame, the only
thing u do is sit on it, if u drop the pressure is on the
wheel/crank/pedals anyway.

So have anyone ever bent or broken a frame?

i saw 2 Torker DX frames on that site, both broken under the seatpost
and both verry rusty inside.
