Concur on above and add @3000 FPS to that short list
Thanks. BTW - I love the "this saw has been dicked with" sign - can you share the story behind it?

Don't know where you come up with this notion of zero success with TIG welding. Where are all these threads?
With a decent TIG machine and the correct filler rod welding up mag chainsaw parts is really pretty easy, I and a few other guys here do it on a regular basis and don't seem to have any significant issues.
JB weld repairs on mag stronger than the original part? You've been watching too many commercials...[/QUO
Let me put it this way I have yet to see any welding on certain Stihl parts be strong any where as strong as the original. Please share what method used with what rod on what part and how over time it has worked perfectly. In more than 50 years have not seen it yet, but that does not mean it could never happen. In 1964 I learned how to use a heli arc with great success and have learned how to set up a titanium booth, but have not witnessed good repairs of Stihl parts. Thanks
WrongYeah go ahead and weld it anyway you want and it will work great, NOT. There are several welding threads on this subject with ZERO success. Mig, TIG, Solder did not work for me, but go ahead and try it again. Tell us how it went. Welding motorcycle cases is a cake walk without any issues, Chainsaws is quite another matter. JB Weld and similar epoxies work perfectly. Actually JB Weld is much stronger than the original. In my case the repairs consisted of making a patch that was at least 1'' bigger in every direction than the crack with aluminum, Of course cleaning to bare metal was essential and carefully crafting the reinforcing patch. Thanks

I'm surprise a $700 TIG gets any happy customers. My TIG was about $5000. Miller 250DX with water cooler.
So you've backpedaled from ZERO success to now not being as strong as original on certain Stihl parts. Didn't realize we were only talking exclusively Stihl Contra where the handle attaches to the case, so no, zero experience there. But still you want some sort of testimonial that all my repairs work perfectly over some unspecified time? And to bother explaining my methods while you already claim to have experience over 50 years with this? LOL!
My most common repairs are cracked clutch covers, I've done at least a few dozen of them (including Stihl) and so far no weld failures. Various crank case repairs are probably next in frequency and at least the ones I've done for myself have been fine. 2 or 10 or 50 years from now, who knows...
I just did a spider web cracked bar mount area mess of a 395 crank case for someone. Had I realized just how many cracks I was going to end up chasing I wouldn't have even started it but became a challenge of sorts. Ended up an overly complicated job that I didn't have a high level of confidence in the finished result, will be interesting to see if it holds up, assuming it gets used.
Cast mag welds more or less the same way as doing aluminum but without the puddled material having such a tenancy to jump onto the electrode. Meaning you can bury it in the puddle without particular issue, so much more forgiving of unsteady hands. Filler rod I use is az92a.
Here's an example that was almost broken in half, normally wouldn't have bothered with such a common part but was just practicing on it. Outside gets blended in for cosmetics, inside stays with the beads to add strength

Have never had jb-weld last on any repair I have made. Had a 056 handle snap and carried it to tig man and he said he could do it but it had to be cleaned completely. He repaired and you can not even tell after repainting.Yeah go ahead and weld it anyway you want and it will work great, NOT. There are several welding threads on this subject with ZERO success.

This might be your lucky day! Have I got some excellent practice for you. Look at this thread and let me know how to prep it and where to send it. So glad I found this thread.
