I've never used a mig and since I don't want to use mine out doors to learn how, I've been practicing stick. I've been able to burn thru 3/16" right easily so I've got a ways to go, maybe by Christmas.

Looks like your circles fit really well.

MIG can absolutely used outdoors. You either need to wait for a calm day to use gas shielding or use flux core wire. :thumb:

I'm installing a predator 670 in 140, and need help to figure out how to install a tachometer. How to get signal from the double mags. Thanks in advance Colin

What kind of tach?. If it is a Tiny Tach style you just wrap the tach sennsing end around a plug wire. Roger

or block off an area with fire proof material to reduce wind and use more gas flow can work too

 

[Colin styf]

It is a tiny tach, what should I do? Strip a length and wrap and how much should I wrap in length?

 

[bloodrunsgreen]

You just wrap it 2-3 times around a plug wire, do not strip any insulation off!

I was able to weld in the extra baffles, one on each side but when I tried to weld the plates on the ends... went South quickly.
Even on the lowest setting I was burning holes through it. I'm going to give it a day and try again tomorrow.
I have respect and admiration for welders!

stick or mig?

with mig I had to turn heat and speed down a lot and use it more like a tig

with stick, you need a thinner rod and lower heat

Steve that really looks good. I tried something a little different on the exhaust pipe side. I ground off all the original muffler from the end. That allowed the end to sit down into the muffler. The patch I made for the exhaust pipe was going fine until I got all the way around and just stopped. Burnt a hole in the side of the exhaust pipe. I was using a 1/8 7014 rod @ 90 amps so I was moving much faster than I think. I did better with that then the 1/16 rods @ 30 amps. I've still got a few holes on the other end that I almost get but end up with an even bigger hole. We are getting a cold snap so I'm going to take part of Mr. Rope's advice and try for some kind of wind block. Then I'll be starting from 0 as I have never used a mig.

The tighter grinding had not been done in the above picture. The arrows are pointing to the muffler shell. On the other end I tried to butt these together but I haven't gotten enough practice in the month and a half I've had this welder and using stick because I'm under a tree. It's not pretty but I should be able to close the hood.

Maybe you can see what I was trying to say by comparing these to your pictures.

No MIG, try some 7014 rod. But a investment in a good MIG welder is worth it in the savings in frustration and time on thin materials.

I've got some E71T-11 that I am going to try as soon as it stops snowing, sleeting, and raining. It will be my first time ever using flux core. I'm sure I will need lots and lots of practice. I also want to build a wind block so I can add gas with bare wire. I don't really know what to expect except that I will need lots and lots of practice.

Welding is certainly not for the timid and it doesn't let you stop to think of what you should do next. Trying to watch learning videos is frustrating as my service provider is below average and they come off very jerky. Not being able to hear any better than I do makes it impossible to understand some people. I often use close caption when available and have learned that some of the transcribers can't understand some of them either.

Even with hearing aids a lot of the digital encoded speech is hard to hear. If you don't have hearing problems count your blessings.

Flux core does a pretty decent job, but MIG using C25 mix is a lot more forgiving. I have learned NOT to get welding gases at TSC, I shopped around and found two good suppliers that don't mind selling to hobbyists if they come in on non busy days. Their prices vary so don't forget to ask for your discount....

I hate the spatter of Mig, love TIG however

 

[wmgeorge]

I reserve TIG for those sit down inside jobs, and the nice thing is most TIG power supplies are also a darn good stick unit. MIG with C25
and the right settings has little or no splatter and its my go to process. My Miller multi purpose machine is now my only welder.

predator into 317 john deer looking for drawing of mount

The muffler is TOO BIG it will not fit under the hood. I will run them topless until I can get a smaller muffler connected.

The driveshaft adapter I bought on eBay it seems to be no longer available. There is/was an Honda adapter similar to what JD used on the 317.

I had access to a SEW Honda 670 kit and copied their mounting plates. Justus Rogers has made plates that keep the shaft at the same height as the Onan that should allow you to use the same belts for the mower etc. When he publishes his drawings I plan to have that type made.

How about the drawing on the engine mount are their any yet THANKS

 

[shadetree]

Smokey4111 - Not that I have seen. Justus Rogers offered to draw what he used but I guess got busy with other things. Several people have just drilled extra holes in the 318. (saw where someone said to watch out for the hydro lines on the left side as one is under where a hole needs to be) The 3/8 inch plates I used have worked for me, they allow use of existing holes.

Just curious if there is any update on this thread? I am looking to do this repower in the near future

 

[Grandprix428@mhcable.com]

Mine is still running and I would do it again.
