I know I am probably out of luck but never hurts to ask. Looking for a SD40 site glass. Also need the Aisin plate. Would prefer Blue Plate but would be willing to take a gray plate if you had one.
 
I thought someone at one time talked of reproducing these... no? I know I saw a thread on reproducing the glass.

good luck with the search

IIRCC it was in the 25 section, he had some demos but just didn't work out, not sure where he is with it now.
 
I haven't really had time to revisit this project. I have the molds created but couldn't get the tempering to work. I would produce a molded glass only to have it shatter out of nowhere. Glass is a fickle object.

If anyone knows of a glass company who could take the project on, I would gladly supply the molds to them. I can also make more molds pretty easily.
 
A funny story, went to look at an fj45 years ago and it had a big window sd40. Guy broke the glass, so he made one out of plexi glass..... and it had been working for a few years! Defeats the whole cool factor, but maybe an option for those without one?
 
i spent quite a bit of time trying to move this project forward and @Krondor helped with a CAD file but i seemed to strike out at just about every turn. I did find a company willing to make the mold and provide the finished product but it was $6000 for 100 pieces. The 60 bucks a piece isn't bad but i don't have that kind of money to shell out upfront and hope i find 100 buyers. I had one other specialy glass manufacturer in Cambridge Ohio that seemed interested in trying to make it work. Unfortunately he is 3.5 hours away and isn't open on weekends so i have not found the time. Also working with @BenCC to 3d print one but he had not yet found a translucent media that would stand up to the gasoline/ethanol. Last option may be to just use 5 mm thick glass and run with it. Just would like to find a better solution.
 
Is the Aisin embossed on or engraved in the glass?
 
The aisin name is on the blue or gray plate not the glass.
 
Just a thought. One could engrave the backside of the glass with Aisin and paint the back of the carb chamber blue or gray with fuel resistant paint/chemical.
 
With the stated above casting; couldn’t you do a thick clear plastic that’s sturdy and resilient enough to stand the test of time? Someone smarter than I should know what plastics might work.
 
I loaned out a back plate to a member years ago to try and reproduce it and he had no luck or way much minimum order to justify it.

With regards to plastic. I contacted a number of plastic companies to see if they could suggest a polymer that was gasoline proof/resistant. Most came back with no suggestion and the few that did were not transparent.
 
I am thinking I will be getting a visit from @Land Cruiser Junky soon. He has worked with glass his whole life. I will ask him about cutting some flat glass to spec so at least we can get a few dead carbs back on road.
 
Any help would be appreciated. Pm me or @kondor for the CAD file

I'll try to get by sometime next week Mark.
 
Hey guys, as long as Mark can provide me with a sample for the shape and thickness I can knock these out for you. It can't be any harder than cutting new glass for the cluster and I just did that for my LV a few weeks ago. PM me if you need one. Someone post up a pic of one with a quarter next to it.

BTW, for the most part you can't beat glass verses plastics or lexan. Even with the heat the engine produces I don't think this glass would have to be tempered.

I just received info on this glass and see it's cast glass. Now I understand why it's so expensive to reproduce. I'll check out an original at Mark's Off Road but it looks like I will probably make these out of 1/8" clear flat glass.
 
Gene, please check your PM.

I have recently acquired a parts Aisan DW35 carb that has similar size sight window but surprisingly Toyota decided to make that in plastic. That carb is on the way to me. Once I get that I will make few inquiries on reproduction at my end as well.

I saw this at a swap meet a couple weeks ago. It’s a Nissan. Wonder if the glass might crossover. Didn’t buy it and didn’t ask how much.
