CB350 Built by a teen (Weld Now, Grind Later)

[crazypj]

Cool, progress at last ;D

 

[The_Beave]

This thread gets more complaints that progress isn't being made then actually commenting on the progress that has been made.

WTF!

The header is the second to last major fab work (on my end) to be done. Most of the rest of it is up to Dave in prep for the fuel tank setup.

*shakes head*

You guys are really strange.

After 173 pages I think people are just burnt out.

Looks pretty good though.

What's the go with the big sleeves on the headers where they bolt to the head?

 

[The_Beave]

Locking collars. Easier than solid, will still allow for good gasket crush and help center the pipes.

 

[ronnie]

Do you have to weld spring bungs or anything to the head and collors to hold springs? Or am I missing the concept of locking collor? Welds look good to me though, need to give them a light brushing with a buff wheel to make those welds and heat marks really pop!

Are you familiar with how the stock header is clamped to the head? The collars provide a platform for the clasps (made from stainless bar stock) to hold the header in place with the stock studs.

Dave is going to take care of the finish on the pipes. I think he will polish them, to live up to his Nick name. LOL!

How exactly does that exhaust mount work?

The reason that a stock exhaust uses a complete circle clamp is to that it will exert and even pressure on the collets and crush washer. Splitting the collar into two parts changes the camping force and now the studs have a sideways torque - unless the clamps are pivoted around the outside corners. I can't see how those are made to comment.

I can see the tubes being used instead of the split collets but I'm pretty sure the plates will bend when you tighten things up
You'll probably need 4 'C' shaped clamps with holes at end of 'C' to provide even clamping pressure (and a good seal)
Personally I would have made 1 piece clamps and slid them on pipe before welding the flange

A. We couldn't drill the plate out enough with available equipment.
B. No machine shop locally would touch a job as simple as drilling/boring 2 holes in the flat stock.
C. It will be fine. If not, I'll weld the two halves together and call it a day.

*shrugs* I've seen a lot worse sealing setups that work just fine.

I just had to join in . Beat on Dave for us will ya

[The_Beave]

Well, I would if he were being lazy, but he's been busy with work and school and keeping his daily running. I've been busy working about 65 hours a week.

So . . . yeah. The next stage is coming, though: Fuel tank!

 

[Bert Jan]

Sooo Rocan, you done yet?

 

[Green199]

Sooo Rocan, you done yet?

Please don't tease the animals.

 

[crazypj]

Pretty sure it's all done until he gets married and has a couple of kids
We should probably come back in another 20~25 yrs :

 

[The_Beave]

He's been busy with school, work and getting his daily straight. I've been busy working a crapton of hours. I think all he needs to run the bike is a tank and to finish the body. Then put it together.

 

[crazypj]

Hey Beave,
don't be making excuses for him, he's 'lost the plot' and bike is so far down his list it fell off

 

[Rich Ard]

This would have been better as a love story

 

[Ringo]

Hey Beave,

Bingo

 

[Hoosier Daddy]

...all he needs to run the bike is a tank and to finish the body. Then put it together.

Honestly?
That's all?
So we will have what, two more years of this shit?

And to think he started out back in '09 with only this...

beat him extra hard for me
