Just assembled my Elite Journeyman. I noticed that the Y rail gantries only have about 1/16" clearance over the table top. Is this correct? Seems like there should be greater clearance. I notice that the Foreman assembly instructions indicate adding a riser block under the Y rail bases. Why does the Journeyman not have the same risers? ---

The woodworker has about 1/16 as well, pretty close pat ---

Hey Brian, because the Journeyman has the 35 mm rails on Y, while the Foreman has the 50 mm rails on Y ([see difference](https://forum.onefinitycnc.com/t/differences-between-x-50-rails-upgrade-and-x-35-rails-standard/6033)). Only on the latter it’s the carriage that protrudes downward the most, and not the feet. ---

That’s why I added risers to mine when I assembled it. Also gives my fingers room to get under the rails for cleaning. Pony ![Compress_20230417_134110_0787](https://us1.discourse-cdn.com/flex022/uploads/onefinitycnc/original/3X/b/3/b36065b27fd6b9de52bcb7917e0f9e3c9356eb20.jpeg) ---

Thanks for the replies. Appreciate the photo @Pony . That’s what I was thinking of doing. My concern is that it could be possible to get a chip under the gantry that could cause a bind. Maybe that’s a bit of an extreme scenario. But I was also going to ask if there would be any downside to putting a plywood spacer under the Y bases. Looks like it would be Ok. ---

Ideally they would be machined metal pieces, but wood works, especially hardwood. Pony ---

I did the same with a piece of Maple. 😉 ---
