If I owned a Linhof Technika IV or V, would I be able to get a new cam specially made for a lens, who would do it, and how much would it cost (roughly)?
Many thanks!

Richard Ritter can make them. You would have to contact him as to pricing.
Thanks.
Bob Watkins (Precision Camera Works) is the current Linhof-authorized, factory-trained agent for providing this service in the US.
It's been ten years (!) since I had lenses cammed for my Technika, but at this point I think you can count on the price being at least $200 per lens. The latest Linhof price list shows a charge of 284 euro for camming of customer-provided lenses at the factory in Germany - see p. 8:

But best to contact Bob and/or Richard for a firm quote so you'll know exactly what to expect for service done here.
Many used suppliers and individuals on the auction site offer loose Linhof cams. It's a fairly simple matter to check and touch up a loose cam for the same focal length as your lens, and it may be accurate enough to satisfy you as is. Make sure you get the correct cam for your generation of Technika IV-V and Master are the same. Set your infinity stops, insert the cam and check RF image at infinity. Is it right on or has it failed to converge or possibly gone past convergence? If it is right on, start checking the RF against the ground glass at closer distances. If the RF fails to converge at infinity or at some other distance, then the cam can be touched up carefully.
Watch where the follower wheel rests on the cam. If the RF has not yet converged on the target on the ground glass, the cam is too low at that point. It can be stretched by tapping along the area in question with a flat machinist's hammer against a flat steel surface and smoothing with a fine file. If the cam is too high at any point along the curve, it can be taken down with a fine file. You will see evidence where this work was done at the factory on IV cams before the bodies were standardized on the V and M. Working slowly and carefully, and checking frequently at a number of distances, it is possible to craft an extremely accurate cam for your camera from either a loose, used cam or new blank.
Great description of a doable process.
Thx!
