McCulloch Chain Saws

[promac850]

Really. I would have guessed some large frame saw. Ron

I'd be the guy churning out Super 797's... and saws that are on the same frame as well.

It would take some money, ingenuity, and work, but it's possible to start making brand new old McCulloch beasts...

Check this thread out... this guy started his own little foundry. Casts aluminum parts using old broken aluminum parts off of VW's. Mainly watercooled ones, such as the 1.7/1.8L equipped Rabbits, Jettas, Cabriolets, and such... VWVortex.com - The complete guide on casting parts

Mods, please exclude this link from deletion... just want to show that casting stuff, with some knowledge and practice, can indeed be done by some handyman in his backyard, with a few tools, even self fabricated...

100cc 10 series

795

I recently tore down a target 795 that had been used and abused hard. I have a nos short block
for a target concrete saw and would like to know if and what other saws this block would fit in.
I also have a nos 105/125 block and what other saws this would fit in besides a 125. I have a 101 kart block,crank,head and the colored tin work for a 125 conversion,all nos. I can't post any pictures yet,I'm still working on getting a handle on this posting. Mark H can verify that I do have
these blocks as he has seen them. No these are not sale,just looking for some information,good,
bad or indifferent.:smile2:

I want one. Read an old post today that said the 10 series tooling was still in storage not too many years back. Ron

100cc 10 series

Dood. 100cc in a 10 series package would be deadly. I'd take one in the non AV version, but a SP100 does have an exciting ring to it. uttahere2:

all we need is 5 or 6 million bucks to get started.

You are truly blessed! The 101 kart engine will work in the 795/797 and gear drive versions as well, and leeha has demonstrated that. If I recall, the 795 was 103cc, and it will retrofit into the 105/125 versions as well. Jacob J has a pretty good explaination of the differences between the +100cc Mac engines around here somewhere. I'm sure if I am wrong, someone will be here shortly to correct me.

One good lottery ticket. Or for a few thousand, we could bore a dozen 82cc MACs to 2.28", plate them in Nikisil and get Wiseco to make up some pistons. 100cc+. I wonder if the crank and clutch would hold up. Ron

I'm afraid you guys are missing the boat. Randy's idea is the sexy one, noise vibration arrgh arrgh arrgh. Mark's idea of the BP-1 is the practical one, and if you've never run one you are truly missing something. It will cut with most stock saws 20 years newer, and was light years in front of even what Mac was doing at the time. Vertical engine, boost ports, thats what I am saying. Just saying.

While we are dreaming, keep the Mac port design, but use a three piece crank with a one piece rod, have J&E make the pistons, and have Walbro tool up a 1.125 venturi carb. Stand it up so you could get a muffler with the desired volume. and isolate the engine bed with spring AV. You'd end up with a package similar to the Partner P100/Mac PM1000, but make sure you style it to be more attractive to the eye. End result would not be close to the classic Mac horizontal styling, but it woud run the 3120's and 880's of the world out of the woods.

Lets get these guys to market the saw. :hmm3grin2orange::hmm3grin2orange::hmm3grin2orange:

Unfortunately it would take more than 5 or 6 million to get past the federal government(EPA), they would never allow such a product to be made here in the US.

Why do I want to make a sandwich after I see this video?

The boring orange and white ones are made here for the most part. Plenty of saws sold at Walmart claim to be made here. And them guys couldn't market a sammich to hungry people.

But I agree who the biggest roadblockers are, the ones with the blockiest heads.

'cause it was cheesy and full of baloney.

When I seen the video it reminded me to get TP while Christmas shopping tomorrow. I looked at the website, and that saw isn't in the products yet. No sandwiches, either.

The PM8200 already has these little features. Ron

I thought the BP-1 had a little - ump, weight problem. Not so? i also prefer the horizonal engine. MAC did the vertical thing years ago. Ron

 

[RandyMac]

vertical cylinders are so 1950s.

 

[promac850]

vertical cylinders are so 1950s.

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.

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...
