How weird that the 52 cover fits on the 111.....maybe it's an age of design thing.

Actually Scott, I think I bought an old 52 for dirt...just in case anyone ever wanted parts on it. Let me check it out. I can pic and measure stuff so we're sure....if I have it.

Kevin -
I’m not sure why the 52 is compatible but the 621 and 80 definitely won’t work.
Please let me know what you find.
Thanks!

You bet....

How close does the 80 top come to fitting, or is it an entirely different shape?

The 80 is close but it wouldn’t completely cover the points cavity. It also only has a screw in the middle. The 111 has 3 screws holding the cover. They are basically the same shape.

Wow...three screws??? I know the 80/90 have the one.

Well, I'm guessing if I get inside that 52 and it has three hold down screws, it has to be your boy.

[Real1shepherd]

Scott....hopefully, I made your day. This has to be correct;three screws. Let me know if you want the three screws & washers along with the Woodruff key. Or any combination thereof....I don't care.

Anyone else needing parts from a 52?

Kevin

 

[bulletpruf]

Kevin - Excellent! I need the cover and the three screws. I don't need the woodruff key. I'll send you a message.
Thanks!

Hey Kevin you don't happen to remember what type and thickness of steel you used to make the dawgs for your 80 do you? I have to make a set for my newly acquired Sachs Dolmar 133.

I worked for a gold mill in CO at the time and fabricated from some plate steel they had. I''ll go check it out on the saw!

Kevin

 

[Real1shepherd]

Looks like it was 10gauge. I have no idea what kinda steel it was....could have been hard plate, for sure it wasn't just mild steel.

I probably put some thought into it at the time given what we had at the mill.

Kevin

 

[Clyde85]

I made a pattern but it doesn't seem to want to harden. I think it just isn't very good steel.

Wes..

 

[Real1shepherd]

You could try heating it up to like maybe a straw color and water quench. If you want it harder, heat it to cherry red and oil quench.

Kevin

 

[Clyde85]

Thanks Kevin. I tried cherry red with the water quench. I am new to the heat treating thing. But because two kids in one of my daughter's classes tested positive for covid I seem to have some time on my hands untill I can go back to work. The kids aren't showing any signs or symptoms yet.

Funny...a 52 just came to me today. I don't know much about them,looks like it's seen some use!

Wes..

Try it with clean oil. Most metals today are geared for oil quench. That's what the reps used to tell us. I don't know about raw steels from China though.

Kids don't always show symptoms(asymptomatic), but they can be great carriers.

Kevin

 

[Clyde85]

That's what I hear. That's why we have been staying home.

 

[Clyde85]

It was just a piece of scrap steel I picked up at work in the maintenance shop. I am not sure what it is other than to soft.

 

[ErnieG]

So my next project .. Jonsered 930
It has some scoring all on the exhaust side of the cylinder . I would assume it got very hot because some of the paint around the muffler was black from the heat . The saw was absolutely packed with saw dust ..all the cylinder fins and all around the flywheel so I'm sure it wasn't cooling properly.
What would most likely of been the culprit for this ?
Thanks!

[Clyde85]

The young ladies first test came back negative today. Hopefully we won't be as long getting the results of yesterday's test.

Wes..

 

[Clyde85]

I would guess a air leak or straight gas.

 

[Clyde85]

Second test came back negative.
