It's got all the provisions for a brace just never had one, but of an odd ball.

Do you have to drop start it or is it heavy enough to pin to the ground and pull without having anywhere to put your foot to help hold it down?

The 1-42 and 1-43 models were originally released without the lower brace. The 1-40 thru 1-43 models have no bearings in the piston for the wrist pin.

The saws just look broken to me without the lower handles.

It could be pinned down by the handle, she ain't light. Myself, a walking OSHA violation, I drop start just about everything.

Here is something you are not likely to see anywhere else...









I will have to remember to find the old Popular Science magazine that had an article on the McCulloch Plywood Saw. If I remember accurately, they went on about how fast this would rip a piece of plywood compared to the other saws available at the time.

Very cool Mark - That is definitely a piece that needs displayed in the Dike, Iowa McCulloch museum.

That's awesome, it will look really neat when you get it cleaned up!! What size chain does it have? Is it scratcher chain? Looks like it has two of the same cutters and then alternates...neat!

I really wonder what the point was to not use bearings, I know it saved some money but they’re must have been a fair bit of rpm difference between the two versions and I’m sure the bearing ones had more power. I have a real nice 1-41 but just wondering how slow it is to cut with because I’ve never used it even though it probably could be made to run fairly easily.

 

[heimannm]

It is scratcher type chain. I'm still trying to figure out where I put the stash of Popular Science magazines so I can try to find the article that featured the BP-1 plywood saw.

They built a prototype 399 twin snowmobile engine also with the ballance/charge piston set up too.

I got the SP60 yesterday & went over it quickly,then I went out for lunch.It seemed to have pretty good compression & looked to be in great shape.I came home & checked it for spark & got it to fire.The fuel filter looked new,so I didn't bother changing it.I fueled it up & in a few pulls it was running,albeit at a high idle.I turned out the idle screw about as far as possible & it seems to be about right.The manuial oiler works.I went to shut it off & it didn't.I played with the switch a bit & then it shut off.I went & got some spray lube & shot some onto the switch & it's working as it should now.I think I lucked out on this one.It also came with 3 chains that are like new (one of them is new),2 extra spark plugs,& a scrench.

Congrats, nice looking saw!

Looks nice, far as the high idle may fatten the low a touch to drop the idle speed if the idle adjustment screw is all the way out.

They are very smooth, and very fast...

I really want to throw one in an old sled like they were meant to be... something super nice and clean.

Sure wish they would have actually made a run of a decent amount so a person could actually run one and have some spare parts available. China clones maybe
Actually on second thought can’t imagine a China clone of a bp 399 coming apart at speed between your legs on an old tnt or skiroule ect.

So my wife's uncle actually has one that he bought from a crackhead in Arizona. A complete, slightly rusted BP-399T. He says that he plans on giving it to me... we'll see. He races bikes and karts at Bonneville.
