North East Tennessee Saturday MAC Report

Beautiful day in NET today though still on the warm side at 68* presently.

I thought I had 7 or 8 Ash lined up to fall today, but the fellow in charge was out of town. Just as well, the woodlot boss doesn't want anymore wood at the lot until they reduce the load in the yard, and more germane to me, my shoulder and neck are giving me a fit. Been building up since Labor Day weekend when I spend all weekend plus a half a workday moving and spreading dirt.

Last I heard, Brian was doing some light cutting down at the lot this morning. I took care of some wife and daughter things, then scratched my head wondering what MAC related matter could I report on today. Bingo, I need to make a new bottom shroud for the 800. So I when down in the lab and found my original dimensional model. Back in the driveway and using my tailgate for a bench, I removed the two remains of the old shroud. One piece was no bigger than a lock washer for the screw that held it. The other is shown below with the model; nothing of it left to cover the cylinder fins.

You can see from this picture why a bottom shroud is necessary to direct cooling air through the bottom fins.

Not having the proper tools, I did the best I could with pliers, a vice and a miter saw. You got to count your fingers when cutting thin aluminum with a miter saw and then count them again when you shut off the saw. My count came out even, but while making the last cut (actually just a 1/4" nibble) the blade grabbed and torn the piece - ruining it in the process. I had to make another one. Sprayed it with the only yellow paint I had on hand; doesn't match and with a half clogged nozzle it came out pretty ugly and runny. It is hard to see in the picture, but if you squint you can see I pressed two ribs in the piece to stiffen it. I also put a 90* bend in the rear for the same purpose.

All put back together.

I fired her up for fun and to help cure the paint. Maybe next week, it will see some wood.

Be safe.

Great fix Ron. I like cobbling up stuff too.

It is a cobble for sure, Tim. Some of you guys with skills could make it look factory and have all the reinforcements in the right places.

“Function over form!” That’ll work just fine for a user chainsaw, I like the idea of upgrading weak points as opposed to continually replacing a poorly designed part.

Cobbled chainsaw parts?

How about my homemade muffler for my PM Canadien 270, haha. The NOS muffler I tracked down seems to be held up by Covid (for how long who knows) so it looks like this will have to do for now at least. Imagine what this will sound like on a 95cc saw:

I used your original design for a help to build mine but I used 1.2mm steel sheet instead but not exactly light though.

Great fix Ron. I like cobbling up stuff too.

Good to see you around Tim

Doesn’t SC have an open container law? Guess it doesn’t apply to empty ones.

Officer: Sir, I smell alcohol. Have you been drinking?

Driver: No officer, I am just working on my floor boards.

Ron
Dont be silly, South Carolina doesn't have laws! Have you been here. Lol

The rest of the saw actually looks to be in decent condition (other than the pound of gunk caked in the pull start cover), but obviously this is bad news bears. There's a hole in the bottom of the tank under that crust, I think where the filter was sitting, so it'll have to be patched up after bead blasting. I've got another saw that could use some tank sealer though, so hopefully I can get a two-for out of the little can of POR-15 tank sealer I got.

A few days ago I'd reported that I might've found a source for an aftermarket domed air filter for the 10-10.I received the air filter today & I'm happy to say that it's a fit!
Here's the contact info:Woody Strommen,Monroe,Wi.,Phone # 608-558-3145.He sells other Mac parts too,bar plates,etc.The air filters are $16 + shipping.

No, but they have snakes and gators, don't know what I like least, stupid laws, or snakes and gators. I did take two real nice wild boar down in Hemingway a few years ago.
Snakes don't bother me and its a good thing as its part of the territory when work for the parks.
Hogs up in the mountains are very clean( disease free) and some of the best ham and loin in the world. Acorns are littering the ground this year there gonna be some big hogs this spring!

Sounds to me like classic condenser problem.Unfortunately Mac used Phelon condensers & I'm told by Bob j.that there are no more to be had.But if memory serves me correctly,Homelite used a Phelon condenser in one of their saws that had the clamp needed to secure it like the Macs do,I just can't remember which Homelite model it was.
Anyone have a chart for what Plelon parts fit what saws. I got a few in a "lot" I got some time ago but have no idea what they fit.

What do you have?I might be able to research them for you & find out.I hope you know there's no guarantee those condensers will be any good,they can go bad just sitting on a shelf.

Yup, they are old. 00607-00-C, 07053, 05845, 08518-02-A, 08466, 07047, 08466, 09072-04. It is a mix of condensers and points. Back when I got them I spent a little time trying to find out what they are for but had very little luck. Good luck
