Thread: LeCoultre questions

No luck yet on the threading. LeC was a watch maker and my local clock shops have not had a screw plate that gave an answer to the question.

Second question, on the very fine lapping films,3�� or 1�� which side -- the slick or dull side is used?
Thanks in advance.

Dull side is the correct one.

Glad to have you back among us! A few of us got adjusted in the last year or so.

Thanks, reason I asked here was the original discussion occurred here. Guess I will have to cut some brass and see if they fit. I didn't want to try some LeCoultre screws in the small dies I have.

Yup, smooth side down. Lowes sells a 10X3 in glass tile for about 5 bucks that once lapped flat, with a diamond plate, (quick & easy to do) makes a great substrate for film.

You will see the high spots.

A piece of copy paper under 1um film makes a great finish, polishes the edge of a 1um edge. 1um over paper is a very comfortable edge.

Diamond film is not 10 times better than Aluminum Oxide film, in fact not a better finish at all, certainly not justifying 10X the cost.

Gave the LeCoultre a run tonight after polishing, lapping on 3 micron, then one micron and finally on plain leather. Very smooth shave WTG and ATG, I like the blade shape, reminiscent of my Gratian and cast steel Londres. Couple of weepers, alum bloc was not painful, witch hazel, Pinaud Clubman and finished with Nivea sensitive post-shave balm.

No blood on face or clothing.

No problem at all. I have done similar & it was moved. No big deal though.
Do you need a screw for a Lecoultre razor?

Its not a LeCoultre. I don't have it at hand but its one of the French copies. The screw is damaged but the threads in the razor are still good. It needs a lot of work to get shave ready. I want to try my hand a cutting a screw that will work. Thanks for the offer.

Oh, okay. I have another make so I took the screw out of it & although pillar looking, the pitch was different from the Lecoultre so no telling what threads are in it. I have another 2 day set but a different maker, Veritable Vincent & it has a screw around a .60mm pitch & 2.8mm diameter. I guess if you could get your hands on some metric screws & they them carefully so you don't damage the threads on the razor. If you find one that fits, cut the head off 7 make a small slot in it for the screwdriver. That is how all of these are, with no heads on them. Kinda like a long set screw.

Break off a round toothpick and use it to check the pitch and diameter of the threaded hole. Just twist it into the hole and it will leave marks where the thread is at the root diameter. It may also tell you the outside diameter of the thread.

Just had another shave with the LeCoultre, after a few trips to the carborundum strop, horsehide strop, linen and latigo strop and some more on the short paddle plain leather, it did a very good job on half the face WTG and ATG. Had just finished a Genco about 4/8 for my grandson. I had given him a 6/8 M. Jung for his Bar Mitzvah, but it is too large for him now. It still needs more time on the strops, but it gave an unbloody shave WTG and ATG. Not as close as the LeCoultre but not rough on the face.

The round toothpick sounds good, but right now I have only flats and a 750 count box.
