might also be wise to just trace it on a piece of paper, and scan that.

this way you avoid shadows (which is common when scanning 3d objects on a flatbed)

try to trace as close to the object as possible (mechanical pencil), and then you can scale a traced drawing quite easily in any program

@ivan35mm Have you used sendcutsend.com before? That looks like an interesting idea.

yes. great company. i prefer to bulk order with them, however. they don’t have a “minimum order” per se, but if you order 1 item it’s like $30. if you order 20 items its like $35. so it makes sense to stock up. i’ve used them for laser cutting aluminum & steel. they have plenty of good materials and thicknesses to choose from. Sendcutsend is very fast, as well.

I also really like Xometry. great material selection for 3d printing / machining. little bit slower, but always high quality work.

I received the 90mm cam: it's exactly 40mm in width, and approximately 1mm in thickness.

Are you using a recessed lensboard (like from the super topcor 90mm)?

Haven't used the lens yet, it comes to me soon. I ordered a standard copal 0 80mm flat lensboard for it.

You can use a 90mm on a flat lens board with a horseman. The designers used a recessed board so that the same lens stops could be used with the 105mm 3.5 lens.

Sounds good. It seems like with a flange focal distance of 97mm I'm going to need to adjust the infinity stop about 5-7mm farther out vs the Topcor lenses. My horseman is missing two of its five pairs of infinity stops, but that should be no big deal.

If you don't have enough lens stops you can make spacers that go between the next lens stop and the standard you are curently using. Someone here once brought this up. I don't remember who but I used his idea. So speak up if it was you.

Do you know if each factory cam is the same? I read somewhere that Graflex adjusted each cam to the lens provided with the camera. I would be surprised if this is the case.
