@deema , thanks a lot for the closeup shot of the safety nut. I get it, and have reassembled the column according to this. No crane in the shop made the wheelhead carrier handling pretty funny. Care was obviously necessary to prevent damaging the restored column roller guides when dropping the...

Hi @deema, and thanks for this very responsive answer. I now realize my safety nut understanding was way out in terms of potential situation it was made to adress: I figured it was made to ensure the nut and swcrew stayed perfectly aligned when the end of the screw leaves the nut on the extreme...

Hi @deema, as indicated int the 540 valve block thread, I am also rebuilding a 540. I am currently reassembling the wheelhead carrier into the wheelhead column, lowering it onto the Z screw. I am scratching my head on the safety nut orientation (part G12639/imperial, G13174/metric=mine). It is a...

Thanks for your answer, @TFrench, no worries ! Tha was just a ping - check for it once you get a chance! I am still quite a long way from reassembling this lever - the valve block needs work before that - The part is not very difficult to remake but I am still interested in saving a few hours...

Hi @TFrench , did you have a chance to check if you happen to have the broken lever latch I am missing ? regards,

Hi @Badee ! did you have any time to test the gaskets you have been drawing ? If so, I am very interested in the drawings as I am soon to work on the valve block assembly. A friend tried to laser cut the ~0,35 Klingerite material I usually use and it gave pretty good results. The cuts are not as...

Hi @TFrench , thanks for the information. I have a small broken part : the trip lever latch (reference N7511 on page 26 of the parts list posted by @Badee -- it is not listed in the more recent parts list although I think the part is still present). The part is broken in two pieces, I found...

Hi @Badee ! Sorry for the delayed answer, been away on business for a couple weeks. Work on my 540 goes on with all small to medium castings blasted, primed & painted, enough to keep my evenings busy - the bulk of the machine will be contracted as I have a company nearby. Your gasket looks...

Hi @Badee ! very nice. Interested if you can then share the drawings, I would like to cut a new set too if possible. I did not open/split the valve block yet, but the other gaskets are so old they have become brittle and cannot be removed without turning to ashes. Can you tell the thickness of...

Hi @Badee , thanks a lot for sharing this manual/catalogue - it will come very handy !

Hi @sawtooth-9 , thanks for the welcome. My machine shop hosts a Deckel FP3 mill with most accessories Deckel ever produced for it. I have a Devallière H140E toolroom lathe with quite a bit of tooling. I have a thing for metrology so I am pretty well equipped there as well. I have overhauled a...

Hi folks, I recently joined the forum after lurking here for some time (more about me in my presentation post), and specifically reading @deema's excellent thread on his 540 overhaul. I am also restoring a 540, but starts with a machine in a much shabbier state than you guys, although in a...

Hi there, I have been lurking for some time in the forums, mostly about surface grinding. I happen to have set up a pretty extensive metalworking shop where I recently welcomed a very seasoned (to say the least) Jones & Shipman 540 surface grinder. I was happy to read the nice thread posted by...
