This is what's been keeping me busy over the last few days.

IMAG0436.jpg

I've been collecting the necessary parts and pieces over the last several months and I finally had enough as well as a little time to put it together.
I made this one to fit mt 1986 Wheel Horse 312-8. It's a little rough around the edges, but not too bad for a first attempt at welding stainless with my MIG at home. I have lots of experience with stainless rod at work, but never ran it on a MIG before...There's definitely a learning curve there! I'm still experimenting with which technique will work the best for this sort of application. I'm asking for a TIG machine for my birthday! (hint-hint LOL)
Anyway, let me know what you think...and be brutally honest (yes, I did just ask for that).

Steve, WOW, that looks great, and you will get more comfortable with wire welding stainless. It just takes time. I do a lot of stainless welding with my mig machine, I have found that if I do a series of spot weld on top of each other, they will look as if you tig welded it.

Nice Job Steve !! :thumbs:

Steve, that turned out great! You're too hard on yourself.

Ive been getting little updates via text for the last few days, and it's really nice to see one assembled. Last muffler you will need to install on the 312.

Good grief Steve...what's not to like! It looks too pretty to use! Never a rusty muffler again either!

That's the technique that I had the most success with too. I just seem to be holding the trigger too long as I'm getting little piles next to each other. I think that both of my settings are too high! I wish that I had some scrap pieces to play with, but who has scrap stainless that they can afford to "play" with LOL?

Thankfully I have a little scrap, trimmings off of other pieces of stainless to play with. But the muffler you made looks great. I can't wait to see it mounted.

Wow that looks fantastic! That will be nice to have a muffler that won't rust, and you don't have to keep repainting! Very nice work. :thumbs:

That came out awesome Steve! And you didn't even have scrap to experiment with first!
I know people at work that have welded for years that couldn't do a job like that! :thumbs:

Looks great Steve and should last for ever! What does it look like inside? Do you use any insulation or baffles? This is a topic that would be of interest to many people. With the older mufflers rusting through and new ones where available costing a lot it would be nice to be able to build our own.

You should've seen it before I ground out the ugly welds! I was getting 100% coverage and good penetration, just couldn't make them pretty...yet.

Here is a shot of the various parts that went into it.

Here's the baffle, installed but not welded in yet.

The tubes are baffled as well. I don't have any packing in this one, but I'm looking for something that someone suggested and will try to use it on the next one.

I'm actually thinking about producing a few of these to see what the market will bear. I think that I can do it for about the same cost as a stock replacement muffler. I'll be happy to share the details though. The idea is to get the exhaust gas to change direction inside the muffler at least twice to realize a reduction in noise level. mine changes 3 times. The baffle plate in the middle also serves to break up the sound waves before they reach the outlet. This is all the info I have gathered. I used that information and also cut apart the old muffler to come up with my design. I have quite a few old rusted out mufflers lying around (research LOL) and I checked them out too.
