044 bar plate repair. Owner of this saw had a real issue with
throwing chains. Cut al the way into the adjuster pocket and the
bar plate area wasn't flat anymore.

Ground down to clean metal, then "sweated" out some of the oil
soaked area with Mapp gas then cleaned with solvent. Still very
dirty! Lol

Looks good Adam. It sure was chewed up.
Looks like you took the raised portion the bar sat on down level
also. Are you going to just use a spacer for it.

Saw was a mess ,Oregon faller saw.
Only took. .001-.002 off so it won't be a problem with
alignment.

Oh I am sure I could do those on my Tig welder. If you would
like it is not a problem.

I bet you could too.
Jacks shows they are still for sale and not NLA like I thought.
Out of curiosity I went to Jacks small engines and I can still
get new for $5 a piece 8) 8). I guess I will just add some to
my next big order to absorb the $7.99 shipping. PN# 503424101
SPUR $5.00

They are NLA now. Just to update.

For those of you who may interested in welding this is an 8500
crankcase hit by a chain. I wanted to show this because it can
demonstrate how an edge can be built back up by using a material
behind it that will not stick to the magnesium while welding.
If you do not do this with thin castings such as on this saw it
will just fall away when the puddle forms.

So here is the second part of welding on the 8500 case. You
can see in the before and after pictures that there was a bow on
this saw at one time. I wanted to make look like it never
existed. This was done with a backing material and just ran a
bead along the edge unitl it I got it built up. I did this from
both sides so that there would be enough material to shape when
done welding.

Good evening Roger, could you give me a couple of tips on there,
one:
what kind of material is that you are using for this backing?
two:
what kind of magnesium filler do you use for them, one of the
member her Srcarr52 says he is using AZ92A filler for Solo twin
cover in his video.
Thanks in ahead,
Chy

Yes AZ92A is the same filler that I use on all the magnesium
chainsaw parts I have welded.
For a backing I use any kind of metal that the magnesium will
not stick to. I have used some mild steel and some sheet
metal. I have also used a steel rod.

Thanks Roger, placing a backing plate sounds very nice to me.
Will have a try on this method. Also appreciate this information
on the filler. Will make some report when I made some try.
