Sinar F(2) Parts and LF trials and tribulations

[thedistrictline]

Finally getting back into the LF swing (pun intended), I noticed some play in the rear standard on my Sinar F2, after a successful 645 lens breakdown to clean some shutter blades, I decided to take apart the standard bit by bit as in its current form the 1-2mm play would cause chaos down the image taking workflow

Turns out ( any machinists correct me if I am wrong) Sinar either cheaped out on plastic bushings or thought no one would be using these cameras long enough for it to be an issue. The standard height adjustment clamp uses a small plastic bushing to press the screw against the standard leg

This had snapped in half. Using a intact one from the other standard I successfully fixed the play! Great, now I'm one standard bushing down, wait I have an old F standard and surprise suprise it uses the same clamping method. Surprise surprise this leads to similar problems as it is also snapped in two either through over zealous tightening of previous owner or myself

Does anyone know what I could use to replace it, I will check for spare bits on the world wide web. I fear buying another standard will just be a timebomb of another broken bushing

Reasons unbeknownst to me, Sinar ( or an owner ) also decided to use locking on the screws on the legs for reasons I cannot fathom

I just realised having one intact bushing I could have it scanned and 3d printed multiple times for spares, anyone know of a decent scanning/print service in London? Id rather go in person as not to risk losing the one good bushing I have

Might be the type of plastic and how old it is, you might end up with the same problem if three d printed if you do go down that route then get a high spec nylon type if possible.

I would be trying to put a curve in a 1p or 5p coin and working out a fixing to the threaded bolt somehow. Squashing it edge on in a good vice would be a start.
