Tom, if a guy didn’t have a cnc mill, could that be done with a boring head? Maybe turn the cutter inside and run it in reverse? Just thinking out loud.

[kartjockey]

I think you could absolutely do that.

That is going to look very nice.

I thought I should mockup the exhaust.  Sure glad I did!  The rear backets had to go.  I made new ones and while I was loading up the frame to take it down to my work to weld it I got a surprise.  The chrome parts finally made it!!  13 weeks.

Just waiting on the sheave now.  But shouldn't be long.  I am trying out a different chrome shop.

Were the brackets in the wrong place? Is that Wayne’s exhaust?

That was like Christmas in May! That's some nice bling. It will look good in the Portland sun. Bob

Dual exhaust is Simplex.  After bolting the underneath bracket in to place the rear mounts were just so torn and bent that they weren't about to line up.  I started to straighten and begin to save them but reconsidered and made my own.

Making new is sometimes a lot less work than fixing old, rusty stuff.

If it's like PD said about Ricks' tank, they were using my exhaust to do it with!  I ended up taking a jigsaw and cutting an end out of the can to be able to get it on the horn of my anvil and straighten it.  When I was done, I inserted a disc and brazed it in. Braze is a funny thing.  The cap brazed beautifully.  Just played the heat and it flowed right around.  I had minimal polishing, and it quite nearly looked as if I never cut it out.  The header tube on the other hand......! 

The header tube had been brazed.  Seems to be by simplex as the other tubes are brazed as well.  but it was cracked around it so I thought I would touch it up with some more brass.  No way!  It popped and sparked and fizzled.  So I back-up and just took the tube right out. Then made a new one.  The can was fatigued considerably hence the support ring. I bolted everything in place to tack it in position.  Then went back at it with braze.  Much better. 

Here are the before brazing pics.  But the exhaust is under paint and drying as I type.  I will be running some Kerr style chrome exhaust tips.

Nice save , Tom .

Too bad they didn't incorporate a 'more effective' expansion chamber when they designed the exhaust .
But , that technology was most likely science fiction back then , if it existed at all .

Here is my exhaust with some chrome attached to it.  When I was visiting Bob Kerr he showed me his idea of chrome exhaust tips.   Simply just the 1 1/4" bathroom sink drain tube. They slip on very nicely.  They are brass with chrome plating.  He gave me a couple to take home. Just cut the threads off of each end then I pop riveted them on the underneath side to hold them in place.

Maybe Bob is giving me that familiar smirk he had right now!

The old skool boys have some really good ideas. You know Bob and Ernie are looking down wondering, "What are these guys up to now?
