Where did you get the stainless defector?

Ernie

Hi Ernie, I TIg‘d three 3/8” SS tubes into a piece of .062 SS sheet. Then drilled the aluminum muffler with the drill bit size that just fit the tubing ID.

Really nice. Does a 362 muffler bolt on or were there modifications at the back as well?

A Stihl spacer was added to the back to stiffen it up, otherwise it will bolt on.

Quick and dirty one I did recently on an older Husky 455.

Nothing new here. Still running the oem spark screen. Opened the outlet up quite a bit to compensate for the tighter woven screen.

Bought a handful of the HMWF deflectors, no stock muffler is safe in this shop now. MS170 got it tonight. Muffler just has the stock perforated portion opened up, it's not quite as wide open as it looks.

Pay attention to the brake handle and the side of the plastic crankcase. I’ve done it before on 039 and the side of the case started to melt

Pretty slick with the spot welder.

Another hack-shack special, 271 this time.

Well, didn't get melty on me but it did do a great job covering the side of the saw in exhaust residue. Added a little flap to redirect the exhaust away from the side of the case, more better.

I need something like this done to my 400 muffler.

400 muffler front. Already made the factory outlet bigger.

This alloy is the worst I’ve welded ever. Seems to reject every filler, even with the coating removed. It sure doesn’t like SiBr at all. 309 SS filler seams to be ok. It’s quite frustrating cause I prefer welded over screw rivet deflectors.

My 446 hybrid. Pipe deflector. I'm liking these for now. They clear everything nicely, don't stain the case or clutch cover, and don't burn the hands when stumping and bucking. My tig welding still suffers miserably, on steel. So 309 wire in the mig with grinding.

You probably need more argon flow.

Would anybody be up to adding more deflector to the factory outlet for my 400c? PM me if you can. Thanks

Would silver solder work ok on that stainless?

 

[Steelie90]

Couple recent ones I just finished. Still working on that tig braze. Alway run wide on bead width

 

[huskihl]

Would silver solder work ok on that stainless?

Yes. Needs to be up around 45% or more to stick

Did you try tig brazing? I would like to think that would stick fine(?). Or is that what SiBr is?
