You do realize this mower gets the name "Coppyrhead" right?

He's going to have to sing the song "Copperhead Road" all the time also.  So, it has worked out fine already...  I'm gettin' into the idea "big time!" :freak:

The only negatives I see is it will get muddy quite often and vibration. And more expensive

I just picked up some tubing at menards for $20. Its 1"X 5' type m .5 thick. I was looking for 1 1/4 to but they don't carry it even though they sell 1 1/4 fitting??? I think 2 1/2' lengths going into a 2" collector should be good. I already have the 2" collector so altogether so far I have about $25 in it. I need to pick up silver solder but I have the torch. Oh yeah I have the caps to close off  the end of the pipes so I can fill it TIGHT with wet sand so I can bend it without collapsing it in. Good thing I have a spare block for mock up since my engine is in pieces. I will try to get started on it tonight but I have a Christmas party tonight so it will have b e later. I will take pictures as I go

IF YOU CAN MAKE THE FUEL LINES OUT OF COPPER ALSO! OLD SCHOOL!  RAT-ROD LAWNMOWER, I HAVE HAD THOUGHTS OF BUILDING ONE OF THOSE! RED WHEELS, FLAT BLACK PAINT, FLAMES, LAKE PIPES, YOU COULD MAKE IT COOL AND STILL COMPETITIVE!

That is a great idea! I have a Murray wide body LT sitting around the shop.... my new project! I haven't been able to work in the garage tonight so I'm going to pick up some brazing wire in the morning and some sand. I got my curved wood out and ready. Should have some stuff up tomorrow.

Lookin' forward to the pics!  Could you tell me the proper flux to silver solder copper pipes?  I have an oxy/act torch and some flat sticks (don't remember the silver %) of silver solder already.

I'm not to sure to be honest. I was talking about it with my old man and he said since the only thing that will need to be welded is the collector pipe then it would be cheaper to braze it. He said it will be the coolest part of the exhaust so I won't have to worry about melting it and braze is stronger then silver solder rods. So I'm going to go find braze now.

once you get the brazing rods, you will need to use a torch with it. I have tried using a propane torch the little blue bottles, and they dont heat up enough. not in my case anyway.

Yeah you will have to buy a yellow MAP BernzOmatic torch because propane won't get hot enough. Funny thing is I went to solder the caps on the end of the copper pipe to fill it full of sand and I got on good weld on then my map tank went dry  :doh: just got from rural king and they have the yellow tanks for under $10 and they sell the whole kit for around $50. I'm soldering Tue caps on the pipe so when I get my bends how I want it I can heat up the caps and the solder will fall off
Have I ever told you I hate typing on cell phones??   :roll:

 you should not need flux with silver solder just make sure your copper is clean i would braze the joints if there not socket welds if you use copper wire for rod you could polish the joints they would appear seamless i think its very hard to weld copper with copper though, seen it done on tv one time
Sometimes i use my own ideas, even if others think i'm wrong.
