Echo 590 I cut out the inner rear facing baffle on the ss deflector and cut that rectangle out on the inside pre inner baffle. It is stupid loud but has a good note.

562xpw falling saws

Old 385 this muffler has seen better days to say the least. Both of these are falling saws on the west coast.

Does the 562XP benefit from that amount of air flow? Looks good may have to try this, no AT issues?

Thanks

Echo 620 with a 288XP deflector added on, richened up 1/4 on H side and sounds like a much different saw now... FWIW No white dogs were hurt by this saw lol

Great thread! I'm getting close to needing to braze my 359 creation. I took the stock cat muffler and after butchering it, sent away for an aftermarket new one with the side pipe. That will stay intact until I figure out how to screen that. Today I took the die grinder and cut the top plate off the old muffler with the screen screw hold down intact, got it all. Got it cut down and ground out smooth enough, tomorrow is final fitting, just needs a little bending and stuff, it is mostly good to go now.. Next step would be the brazing, I have never done it. I bought the cheapo bernzomatic mapp/oxy rig today. It has five different unlabeled rods. Any way to tell which is the best for the brazing I will need to do? I didn't see any labeled silver brazing rod at the store, just some rolls of silver solder, which I didn't buy. If anyone is familiar with those welding kits and knows about the little starter pack, please recommend which rod to use, I assume one with the flux on it? I will clean the area and get the paint off first of course. The pic is the new muffler, the thing on the side is the rough cut plate off the old muffler. Cut out and ground down that pipe segment on the cut off piece since that pic, and made two nice openings for it on the new muffler, it fits pretty good now. Started with the screen bolt stud, then made a wider opening for the exhaust and deflector.. Going to go right back where it was inside back of the new muffler, so I'll have a dual, odd, but dual port there. Just trying to learn new stuff, this welding/brazing.

Ugly 5200 style mm on my 3400/4000 frankensaw . Ugly welds because my mig was acting up, and, well, I'm a farmboy welder.
Drilled out baffle, but screen still inside.

Finished cleaning and smoothing the donor piece, cleaned paint off where it was to be brazed on new muffler. Staked it down to hold with two screws, just barely enough to hold it in place, nothing hanging down inside, cut them off flush after brazing. Then smoothed out amateur globs and painted it. We'll see if it holds! I'll get some proper silver rod and flux for the next project. Hardest part was lighting torch and keeping it lit with proper small blue flame in the wind.

Looks good for your first time.
If I were you I would get some small pieces of sheet metal and practice. Just play around with different Temps. Just to see how it will react.

Sliver is nice but it's really expensive. I would stick with bronze until you fell comfortable doing it.


Thanks, Brian

I would also get your self some 3/32" bare bronze rod and a tub of flux. It's much easier to control the smaller rod and the flux doesn't make as big of a mess.

Also make sure everything is really clean. No paint, oil or dirt.

Thanks, Brian

As soon as I find another little deflector/screen donor part in my junk I will remove most or all of that front tube and add the deflector there. That will be some more practice. In the meantime I'll try it out on some fresh greener wood around here, don't want to use it on the big dead oak, I already started one fire there sawing! hahaha Went and got a jug of water and got it out. That super dry punky oak, man that lights up with the tiniest spark. I also like screens to keep the mud daubers out. So far I like this 359 a lot, seems a good compromise size/weight/handling for a one saw plan, so this might become my official new truck saw. After the muffler is done and I am satisfied with it after using it a few tanks, etc, this might be my first saw to try and port as well, that will be later.
