McCulloch Chain Saws

[homelitejim]

The problem is there is such a good 5 cube saw would a 6 cube saw really be needed? I think if McCulloch thought they needed a 6 cube 10-10 saw they would have built it, as they have built just about everything else. Also the McCulloch 1000 is really compact for a 6 cube saw, I'm not sure you can fit 100cc in the 10-10 frame as the 82 cc is in there pretty tight. Just my two cents.

Bah... we'll fit it in there...

Anyone want to make a liquid cooled saw? 100cc and well over 16,000 rpm in cut... oh boy, who wouldn't want that? On average, a liquid cooled two stroke can run another 2000 or more rpm over the same engine in air cooled format, simply because the cooling is better. Sure, the saw might be another two pounds, but who cares when you can get stuff done twice as fast?

Used to have a 1989 Polaris Indy 500... spun over in excess of 10,000 rpm at WOT... that thing took off like a rocket whenever it was on ice due to the studded track. Hit 90 mph in about 4 seconds. Piped and clutched...

It'd be great to have a 6 cube 8200, but I'm not sure the block could take it with the split on crank centerline.

As for 1/2 in. chain, I have some and some 9/16. If you're not racing, I see no need. 3/8 is fine and you can speed it up. The big teeth only come into their own on the gear drives.

On MacBob's site there is a Mac 790 which is mine. It has a Pm690 (the 80's vintage chop saw) air filter on top, due to the original being missing. The saw itself is Cut-All with the air-vane carb. I also have a Target quickie 790, which I haven't done much with....no time.

Nice. I'd like to have one of those McChop saws. The chop saw pictured on MacBob's site is 795 (not 790) based. I spied the DSP valve in the pics.

 

[Eccentric]

Yep...

The only reason them orange and creamsickle saws went to vertical cylinders is to make the 'sideways balance' better, whatever the hell that is...

Sideways balance? Really?

Horizontal cylinders are the way to go...


8433, I think the BP-1 is a horizontal cylinder set up, not vertical... due to the design of the engine... if it were set up to be vertical, that would make a real clumsy and awkward saw...

The piston/cylinder set up is kinda like a Subaru/VW/Porsche boxer engine... except it's two cylinders instead of 4/6 and one cylinder is smaller and has a smaller piston since it's the balancing piston... I believe the balancing piston also acts as an intake piston as well.

The cylinders on the BP-1 are arranged in a vertical 'boxer' fashion (power piston on top, balance piston on the bottom)................................not in a horrizontal boxer setup like a Subaru engine. The 'creamsicle' manufacturers (and everybody else who could afford to redesign) went with vertical cylinders on their big saws because the USFS mandated that layout to prevent forrest fires (get the muffler out of the duff). That's what killed the SP125's and the big red saws. McCulloch never would have sold rebadged P100's if that hadn't happened.

We will never know until it is tried. Randy and I are only about $4,999,995 short from our first production run. Ron

100cc 10 series

YeeeeeHaaaaawwwwwww!!!! Where do I sign up? I have about 8 or 9 of the 82cc ones and they are more fun every time I run em (which is more and more lately), I can't imagine how much of a beast a 100cc version would be. The 82cc ones will pull 32" full comp in most wood and still have some authority. Gotta say though that i'm not a huge fan of the muffler on the 800 (and up models). Hey Randy, what was the bada$$ setup (bar/chain/spike/etc) for the 82cc's when you were using em regular?

Well I finally have a day off and I'm home so I got my sp125 I told ya'll about a week or so back here is some pictures:

An American working man an American saw and an American truck what more could you ask for besides whisky and women :msp_tongue:

What don't you line about the PM800 and newer mufflers?? Too quiet for you?

If it's like the 10-10s muffler, it makes four turns, goes around about 8 baffles, and through 2 screens.

No wonder it was so carboned up when I got it.

Fixed that...

 

[Eccentric]

Yep. Too much restriction (and areas to carbon up) and weight. I'm not a fan of the "muffler guard" clutch covers (needed to keep you from getting burned or starting fires with that huge muffler) either. Ugly and heavy. My PM700 has one. My SP-81 and 7-10A thankfuly don't.

 

[cpr]

I kinda like the goalie mask on the 10-10. But you're right, it's stoopid on the big bores.

It's 9:10 on the 24th.

Merry Christmas.

100cc 10 series

I dont even have an 82cc version or a running 70cc 10 series. Thats just what I need another to add to the list:msp_thumbsup:.

It's 9:10 on the 24th.

Merry Christmas.

10 more hours and I will be off work to go spend Christmas with the family.

Merry Christmas!

 

[RandyMac]

I have 11 hours 49 minutes to go.

 

[Brian13]

Sounds like you just started? I already have 14 under the belt, just hoping for the rest to be quiet.

 

[rwoods]

Great picture. Ron

They DO carbon up too easy, are over complicated, hard to find to replace, and I don't like the sound. It also seems to me that the difference in sound makes it a little harder to tune the high side on the carb by ear. Just my opinion.

I'm another guy that wants a 100+cc 10 series saw... That things would be a blast to run... and talk about making short work of firewood cutting. Run a 8 (if you deal mostly with hard/medium wood) or 9 (if you deal mostly with soft wood) pin rim and a 28" bar...

And while we're at it, we might as well bring 1/2" pitch chain back...

Santa turned around his sleigh will pass over you, no promotion from monkey status. SHHHHH while the men folk get this straightened out.

Merry Christmas to all, and to shop monkey, clean up them cans from the party and take tomorrow off, next day too. Study the pictures posted here way back on how the BP-1 actually worked so you can continue your apprenticeship.

Merry Christmas to all...

It was a very nice day here today and we didn't have anything planned before the Christmas Eve service this evening so I spent some time this morning hauling wood into the basement then out to the little garage to start all the saws since the day was so nice. I ended up having to give the 1-76 a spritz of prime to get it going, as well as the 036 Stihl. The 840 would not run on it's own at all when I finally noticed the fuel line between the tank and the carburetor was broken. It took about 20 minutes to make it right and now the big saw is ready to go again. As soon as I find my camera I will post some photo's of the whole gang. As a teaser here is the list:

P.S. I also smoked a pork loin this afternoon so we will have something to enjoy for lunch on Sunday...
