 Topic: All crop harvester wood parts
Posted: 29 Jul 2024 at 9:58pm |
Hello all. I’m pulling parts out of hibernation to ship out to fellow forum member. But is anyone taking measurements of these parts to reproduce them. These are some interesting wood parts. Can’t help to think should draw up measurements for future reference.

Years ago someone on a forum (can't remember which) announced his intention of measuring all parts on his 72 and creating mechanical drawings for them in AutoCAD, such that someone could take them and build a brand new #72 if they wanted. I suspect that never came to fruition. It wouldn't be too hard of a job for anyone well-versed with modern drafting software - there's nothing complicated about them; most small design/fab companies these days draft/design much more complicated equipment on a regular basis. I remember reading that and thinking I should do the same with my #90 in 3D CAD software if I retire early or somehow end up with a few weeks of free time and absolutely nothing else to do (hah!). But that'll never happen. And if I ever did have enough free time to reverse engineer an old pull-type combine, I'd have to begrudgingly confess that I think the Oliver 18 was a far better combine than the 72 and 90, and that the Cockshutt 422 was a far better combines than 60 or 66. The Cockshutt in particular would be pretty cool to reverse engineer and build as it was one of the few old pull-type draper combines that could (kind of) keep up in modern, heavier crops.
I do see on the 'GrabCAD' library that someone's created CAD models and drawing of additional guarding and shields for an all-crop 60 to bring it up to 'modern safety standards'. But why they bothered is beyond me. Looks like it was part of a University of Wisconsin project, so maybe they had a 60 they were using for test plots and didn't want a student to get tangled up in it.

Blasphemy! 
The problem with making new machines is many parts have to be made in commercial facilities at the requisite minimum volumes, and that doesnt even consider the sky high tooling costs that often goes along with it. For example, I would like to get new sickle guards made. No longer made in the States, and to get it overseas I would need to make thousands. Lets see, I sell maybe 10-20 pieces per year. Do the math.

If its not an All-Crop, it all crap!

Do you have a lot of demand for them? On my 90, the bar was so beaten up I had a new bar plasma-cut out of AR450 with guard-bolt spacing changed to match the Case/IH sickle-mower pattern, then put on IH guards and modified IH knife to have the Allis head. Worked quite well, and now I can get guards, hold-downs, and sections anywhere. I can try to find the plasma-cut profile CAD profile and send to you if you'd like. I think it cost me about $200 to have the bar plasma-cut, though admittedly that was at least 8 years ago: Steel prices have gone up a lot since then, and I get a pretty good discount on laser and plasma-cut steel because we do it at work (and I can do the CAD modelling on my lunch hour).
It would probably cost someone else at least $400 these days to do the same thing, and then they'd have to buy all new guards and hold-downs and modify an IH knife to suit. I don't know that I'd bother to do it again myself; that was in my younger days when I thought the 90 was a pretty cool machine and worth putting lots of money/time into.

Well, like I said, I sell about 10-20 used ones per year. If I ever decided to rebuild these units I would have to have new ones available. Who would want a rebuilt unit if the parts were unavailable? The need for these parts and the cost prohibitive nature is part of the reason why I do not venture into that area. I have thought of doing mods to another brand like you have a boy it seems like a lot of work. I was given a contact of someone who may help so I would like to see where that goes.
Other parts that are a b**ch are those slip clutch's on the back.
