Possible to manufacture a Horseman 970 Rangefinder Cam?

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.

 

[ags2mikon]

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.
