Ok. Keep me posted and I will inform you on my end. Between the 2 of us, I think we can tackle the project.

I like how it takes a team of people and millions of dollars of scanning/printing/machining equipment to copy something Toyota did 50 years ago. Not trying to joke, it's just interesting.
Also, considering we can 3D print gears, bearings, and chains, a cover with no moving parts should be quite doable with the right knowledge.

the equipment to do that is in the 500K -1M range.
The tooling for a sand cast aluminum part is
probably in the 20-30K range.
Ultimately is a ROI question

I don't care that much about ROI. I just don't want to loose money for the team if you know what I mean! We have a large foundry here in town as well. Maybe it would be worth taking the part over there.
Can it not be done with CNC?
indy,
that's would be most excellent.
my intention was not to throw water on making this happen, but to level set realistic expectations, because my hopes have been dashed in the past.
I am more than willing to help and put money where my mouth is to help the community.

there is no doubt that it can be done by CNC for a 1 off. But if the demand is in the 50+ range, then doing it with tooling is the lower cost and most productive path.

Indy,
I just thought of another path and would be both truely communist (sorry for the term because I am a true american) and capitalist path.
Here is the pitch.
Since you have the most Virgin top cover, your participation is critical.
1. We get the top cover fully 3D scanned with high resolution and we post the IGES or STEP to the forum. This allows any member to get the file and take to machine shop and get it built at a very high cost. This is the communist path
2. Once the file is in the public domain, there will be lots of people who will see a business opportunity. Some will fail and a few will succeed. As those who survive fight for market share, the cost will drop and more and more people are happy and get this top cover. This is the capitalist path.
tell me what you think.
thanks
ernie

and to put my money where my mouth is, I'll help pay for part of for the 3D scanning. actually if we do a go fund me for just this effort, I have no doubt it will get funded. this would truely be a community effort.
Save your pennies. Quote what modeling would cost. Then consider buying the scan file from that other guy from 6 months ago. That seems to be 1/2 price. Work the deal so you send a deposit, then have a verification period to vet the model dimensions against the physical sample from Indy.
It actually has quite a few moving parts
In business terms there is no demand so certain failure.
Ok. I checked into casting this part today. CNC machining is a great method for 1, 2, or 3 pieces run as mentioned above. Sand casting is the best method to reproduce a part in small quanities. Aluminum Die Casting is more price effective on larger quantity of pieces. I think I can have the sandcast mold made for around $15,000.00. Per the email from them that was the rough estimate without more information on the part. That mold is good for 5,000 pieces, however we all know that selling 50 of these might even be a struggle. Once the part arrives, I will take it to our local foundry and see about casting costs. I will keep you all updated. I am guessing right now that I can reproduce these and sell them for around $800.00 each. It really depends on sold orders verse production run totals. The more sold the lower the price. That also would depend if it is a stripped top plate the way Toyota sold them new, or if you need the small parts inside too. Those pieces can be obtained by purchasing a new h55f and swapping the internal parts from what I see. Might be a small difference will need to research that some more. I don't have the part yet, however I will list actual sandcast mold price as well as foundry cost once I figure that all out.
As for purchasing the 3D scan that has already been done, I would rather start from scratch. I don't know who did it, how accurate it is, and the last thing I want to do is make a $15,000.00 mold for something only to find out the first 30-50 parts are wrong and will not work. If you take the additional $750.00 for a new scan over the one that has already been made and devide it by a 30 piece run, what's another $25.00 added to the end price? Seems like a no brainer to me to ensure that the piece is correct.

I agree with you....start from scratch with the most Virgin part that exists...
I know a guy who has spent his career making molds for the foundry business. He made a mold and core box for a turbo manifold that turned out exceptionally well cast in ductile iron. This would be hand made for sand casting. He still does this but in his basement. Let me know if you are interested in contacting him.
And I think besides the cover you will need a select lever and a shaft.

Thanks for the information. I will see what I come up with once is arrives. We will get this figured out this time around!
No problem, I don't see this guy charging anything close to 15k and his will be every bit the quality of what was used 50 years ago.
Guys I got a unicorn top plate no internal shift fork assembly. I purchased a new H55f and was able to use all existing shift fork assembly parts minus two small parts. I searched heaven and earth and the two unique parts could not be found. Took this to my local shop and they spec'd the two needed shift fork parts and Had them machined. Call James or Ian at R&R off-road at 719 465 4594 if you have an empty 40 top plate but a new H55F.
