@jimcisme1 I could see in my notifications a comment you wrote on this video but It's not here for some reason. I'll answer it anyway, Hope you come across it! I didn't notice at first when I inspected the underside of the saddle but if you look at part 7 around 45 seconds in the video, you can see the characteristic round shape of the recess in the turcite like on the Z axis.
No... So the relief in the turcite was to ummmm burnish the turcite or fit it to the surface. In reality the turcite is a bearing so it is not supppppppposed to wear... it is not a brake shoe if oiled properly it has long life. So what they did is FIT the turcite to the harden box ways by applying a very fine grit paper to the ways and in a way polishing them matching the surfaces.
If I ever have to replace the turcite on my machine, I would feel much more confident doing it this way than the scraping method! Would you happen to know the grit? How come you know so much about the Fadal? I am very impressed!
@@BlaiseBarretteThe grit used was 380 Wet dry paper Black in color usually. 3M spray on glue to attach the paper to the column for the head. and i believe we used double sided tape on the saddle to burnish the table to the saddle. You can use the gibs to ensure the hard surfaces are kept together while burnishing as best as poosible. At Fadal the used a custom piece mounted where the Gib block mounts and a teflon pad. Oh and the Gibbs have a history too. Originally VMC45 days they started off bronze. And then when the saving machine design of the VMC40 came along they went to 7071 Aluminum. And then to Steel with turcite and then to back to bronze.

Is the Turcite expensive or just a pain/labor intensive to replace?
It can be quite expensive. I bought some on Ali express where the price was more reasonable.
