Mac 35 saw help

[ted johnson]

Mike Anderson built me a starter from a Mac 35 90 degree drive saw from the mit to late fifties. What I want to find out, is, does anyone have a McCulloch IPL for the little beast? I'd like to learn from an exploded drawing how the weird carb goes together. I don't want to tear it down without a replacement diaphragm-just in case! I put it away after Fremont '09 with fuel still in it, and never got it sorted out due to my cataract problems. I'm about to drain it and add fresh mix, and I hope it'll start up O.K.... I DO know that sooner or later it'll need carb service... Thanks for any info! Ted Johnson

I have the IPL but it is too big a file to upload on this board.
Send me an email and I'll send it to you directly.

hey ted,
before you buy anything let me know.
i have lots of oddball mcculloch saw parts from buyouts you can have for postage.
think i may have a complete mc35 kicking aroun too.

Thanks, Dave. Right now, there's nothing wrong with the Mac 35 except old fuel, and you know what they say: There's no fuel like an old fuel..... The rest of the starter seems rock solid. I was trying to cover future bases! I'm afraid that if i DO need to remove that monster carb (which basically comprises the whole 1/2 of the side face of the mill), I would almost certainly ruin the 50+ year old diaphragm. After looking at the IPL that Scott kindly sent, I believe I will be able to fab an adapter plate and add an old Homelite reed manifold for a PP 58. This will allow an HL to fit up, and problem will be permanently solved. The problem for me, and by extension for some of the guys I help with fab, is that I'm no longer at the laboratory. I need to acquire a Pro/E Wildfire 2, 3 or 4 installation so I can make CAD files for some of the gang. Like on this Mac 35, I need to model and draw an adapter as well as the gasket, xlate the .drw file to .DXF, and have the plate and gasket(s) waterjet cut. If there is anyone with a Wildfire CD that I can buy, let me know! TJ

You need a what?? An' you're gonna do what with it?? Is that legal in all 50 states? lol

[ted johnson]

Hey, Mark! Nope, illegal except in Russia...and there, they send you to Siberia! I refuse to use AutoCad after 20+ years of using high-end CAD systems that actually work. The Swoopsters that Charlie C. and I had at Fremont last year were completely modeled on Pro/Engineer Wildfire 2 from sketches Ron Cubel and I made from his Swoopster original. You've NO idea how much work that saved! Being able to use a CAD file to generate files usable by the waterjet cutting system has saved hundreds of hours and countless dollars, to say nothing of the extreme tolerance capabilities. I've even gotten to where I can get paper gaskets reproduced that way that look like they are die-cut (a real boon when all you have is a torn gasket from an engine that hasn't been made for 50 years...like the KL100 Homelite). We'll get back to the CAD capability soon! TJ

Ted:
Do you remember paper and pencil. I still sketch things then write my programs for the mill. We all know you started before cad. Jack

[ted johnson]

Jack, Buddy! I THINK I could still draw, but I'm a lot shakier than I was in 1987 when I left the board! I don't have a board here. The nice thing about CAD is the ability to do a direct .DXF file translation. I email my .DXF files to the waterjet shop, then go pick up the finished pieces a week later. I don't even need to add dimensions to the drawing! A $35.00 waterjet bill is a lot better than a $300.00 machine shop bill! I just took some sketches to my favorite machine shop, so I can still freehand. Another nice thing about Pro/E is the ability to do a complex model and drawing in less than 1/4 the time it would take to do just the drawing on the board. Also, if you make a change to the solid model, the drawing automatically updates-and, with Pro/E, you can change the drawing and the model updates as well. You can see instantly if your design "makes sense" and will be manufacturable. God knows how many times I've looked at the CAD model and immediately seen a simpler way to do the job.
Shall we all pit together at Fremont like we have the past two years? I will be glad to see you and Al! Ted
