Bought this chain roll

[NorthernLonewolf]

I bought a 40' chain roll and found out that it didn't have any master links included for making new chains. The chain roll is a 1/2" pitch and .063" gauge roll. So now I'm on the hunt for a set of master links to this roll.

Anyone who sits on this vintage saw chain parts is welcome to reply!

his prices went way up. Early last year I bought a set of master links from him for $55.00 and they looked in nicer shape then that.

What brand of chain, and what is the number stamped on the drive link? I may be able to help.

Hi Mark,

It clearly said "40" on the Oregon chain roll. Hope that's enough. Otherwise just ask.

 

[heimannm]

I have a few pieces to fit Oregon 31, Oregon 41, and several McCulloch 503 kit in 1/2" pitch. I also have a few McCulloch P8 and SL8 parts. I don't recognize the "40" designation.

It may be necessary to take one link apart and measure the rivet diameter, bushing diameter, and center distance between the rivets to see if I have anything that would match.

I'll check when I get home. I'll keep you updated.

For 1/2" pitch, this Oregon chain seems to be called "10C" or "10L".

I will try today to see if I can measure the rivers of the new chain loop.

A few

@Bill G , are those yours? I made a calculation of the chain roll I got, and 40' will give my 28" bar about 24 chain loops for my bar.

@heimannm, I measured the inside of a hole of my chain loop with a caliper. This is what it gave me.

 

[Bill G]

Yes those are a few of the ones I have. I am not following your math on the number of loops though if you have a 28 inch bar you will only get 7 to 8 chains from 40 feet

Bingo. I knew I was off there... Google Gemini told me that after I must've given it some weird numbers...

Do any of you @heimannm or @Bill G have a repair kit for a 1/2" .063" chain? This is what the roll looks like...

 

[heimannm]

40' will have something less than 480 drive links. A 28" chain will require around 66-68DL (depending on the width of the bar, the spacing at the tail, etc.) so you will end up with maybe 6 or 7 loops.

Measuring the I.D. of a small hole with a caliper is not exact, but gets us pretty close. I'm showing 0.248 compared to your 0.246.



The bushings on the presets actually measure 0.250"



Or course, they fit in the holes.



The rivets are 0.150" diameter



Outside of the rivets is 0.655", subtract on rivet diameter to achieve 0.505" center distance.



The spacing on the drive links is just a bit smaller and of course the presets to not fit, but they would never be installed on a driver anyway.





They only fit this way.

Turn your chain over, the number (chain type) will be stamped on the drive link.

[NorthernLonewolf]

Alright. Here you go @heimannm

 

[Bill G]

I should have the original presets. I am headed to the machine shop now but I will look when I get home this evening.

 

[Bill G]

Standard Oregon 10AC I have those

 

[NorthernLonewolf]

That's good to know @Bill G I would be willing to buy about six or seven pairs of that then, for the roll.

To you both, thanks for the input. Once again, the ArboristSite has got me covered.

years ago, with a 7/16 chain (a rare size) on a ancient saw. I needed to shorten it by one link.
what I ended up doing was to punch it out, and weld a little on the preset, put it together, and warm it up, flatten with a hammer. Was gentle with it until I could trust it.
