Hello there, new to the site and highly interested in having my saw modified. I am trying to send it out but it seems as though the fella who may end up doing the work has had trouble welding to the specific metal it's made of out of. I've searched through many threads and I haven't been able to find the specific info I'm looking for. I know it's been done! Any ideas much appreciated! Thanks

Thin stainless maybe?
I suppose, it's just he's had trouble finding the right weld. He said he's tried oxy acetalene and it just, "made a mess." So not sure what else to say. I do believe it's thin stainless as you've stated but what I would really like to find out is what will adhere the best... we're both trying to troubleshoot so any info is great. Thanks

The only way is to TIG weld it with pretty thin stainless filler. That's what I would do anyhow
Yup, tig with s/s rod is the way to do it. Not trying to be a cloud on a sunny day but, chances are
if he's already found he can't weld it with O/A it's more than likely burned pretty good.
Might be time to look for a new muffler and a competent tig guy.

As far as I know, it's not possible to weld stainless with O/A. The burning fuel introduces too many impurities. Needs to be done with TIG, MIG, or stick...tig is easiest.
I'm in BC, I'm not just looking for the muffler mod but ported etc... The whole enchilada!

This is the way I like to do them since I don't own a tig.

Amateurs,
Stick? forget it, too thin.
Mig? will work if you know what you are doing
TIG? YUP!
I've burned my fair share of holes doing muff mods with a MIG.
Gave it up (mostly)
Oxy Acetylene with a good flux and silver solder is the only way to fly.
I have joined copper to steel, Brass to steel, and of course stainless to steel.
I don't have a TIG (yet)

You might not think it possible, and I guarantee it will look terrible, but I have welded similarly thin material with stick before.
Brazing and soldering are not the same as welding.
im in surrey. walkers in nanaimo is the only one I know of... dunno if they weld there... I don't port, but do weld/repair...

You are so rite there! Fit it tight, clean it good, use a good silver solder / braze flux and mod away! Use small flame and go slow!!
These both are ss pipe.
It flows wonderful and gives a very professional look.

You are correct the fit is the key however I have bridged almost .075" with it. You have to be awfully patient to get it to do that so don't get in a hurry!
