    Custom parts for lens adapters, etc.

    Over the past few years I have set myself up with the ability to machine small aluminum parts, mostly parts that can be made on a lathe. I can also do anodizing and 3D printing. I attached some pictures of previous work, mostly bicycle parts. I would like to add some camera parts to my "portfolio", strictly for free, so if anyone needs LF-related items made or 3D printed, I would be interested in trying to make the parts or discuss techniques to make them. I have found 3D printing very helpful when dealing with obsolete camera and darkroom parts and the costs are quite cheap now. Laser cutting service is also getting quite economical nowadays and opens up a lot of opportunities that used to be impractical. The picture of the laced hub for example, the round parts were made on a lathe. The sprocket was laser-cut and finished on a lathe.

    once upon a time tool n die men were the n high demand. as machining became automated, those guy were looking for work. now it seems machining is an art and coming back in a new light.

    are you offering services for small jobs or custom work? it would be nice to list you as a resource? there are times i wished i could make a certain part that just cant be found anywhere and if i could find it, the cost just isnt worth it.

    nice work!

    I used to make Dyno to Engine drive shaft adapters that looked exactly like image one

    Short drive shaft running up to 8000 rpm, I made very heavy duty safety covers

    Made those from 1/2" wall pipe, cut in half then welded to large tabs

    Drive shafts did fail, but that red cover just distorted, never let one go

    I love making stuff

    I would suggest making flanges like this one, in many sizes. I can share the technical drawing for one I am looking for if you want. send a pm in case.

    I would like to have Rodenstock Imagon aperture discs made and sets I've bought were not always complete.

    I am definitely looking for opportunities to make things besides bike parts. I can make most threads,

    and reverse engineer existing threads. There's a few things i can't do (like precision grinding) so it just depends on the part. However I have a good relationship with a laser cutter, so I can usually get parts laser cut for a small fee.

    These brakes were prototyped through 3 different versions in plastic, then laser-cut out of aluminum and anodized.

    Everything I make is made BY HAND, that means there's no benefit to making batches for the most part.

    I would be interested if you could makes things out of brass - and would be at the other side of the pond ;-)

    Just out of interest, which threads can you cut? well I guess most common UNC/UNF since these dies should be ready available in the US,
    but do you also have dies for the old imperial (and continental) threads?

    Many of us are interested in having mounting rings made since most dealers seem to separate these from the lenses / cameras when they sell them, and sell the rings apart without providing correct measures, so hardly any of us is able to find matching mounting rings. Also handy is the ability to make little thumbnuts / bots. Just recently had one made when restoring a full plate camera but they didn't have the correct imperial dies for them so the machinist had to cut it 'by hand', and therefore had to make quite a few samples before the thumbnut did fit.

    I have made a few one-off parts by hand. Like this lever for the Graflok back of my 4x5 camera.

    Will keep you in mind if I need something done on a lathe or 3-d printer as I don't have either of those machines.

    Battery doors for the Super Graphics and Super Spped Graphics. Those are frequently lost. I can supply dimensions if you want them.
