Mounting linear guideway on T-Slot?
Hello!
I am relatively new to the t-slot profiles, so once I got a scrap piece in my hands I saw something unexpected:

The parts marked with arrows are somewhat recessed, probably to make the t-nut joint stronger. But what happens if you mount something narrow, like a rail for a linear guideway? Wouldn't it be recessed relative to the profile area? Maybe I need a shim that is as wide as the profile (40mm in my case)?
Can someone enlighten me please? Thanks!

I mounted mine by drilling the the slot to the back. used a screw with an angle under the head surface. slid the screws in the slot and slid a allan wrench in from behind through the hole and tighted. The rail centered up perfectAttachment 263570

Hope the pictures worked.

Hi, Im about to design a machine with this setup, my rails will be wider however ( 35mm ) on 40mm t-slot profile, do you think this problem will affect me? can i do with the washer way?
Thanks!

A washer I hope was just a joke I think,But you never know what some of the posters are thinking, Linear Rails need to be mounted on a machined surface, it will depend on how much clearance the bearings have, as to how flat the mounting surface has to be, if it is not flat enough for the bearing clearance then there will be binding & jamming of the bearings
Some suppliers that sell the aluminum extrusion, do offer it with a machined surface, the best way to mount them is on a machined plate with a shoulder, to suit the rail, so the rail can be fitted up against the shoulder, this helps to keep the rail straight
The rails are not straight, so need a straight/flat surface to be mounted on

Here is one that offers a mill surface, for linear rail mounting,( Misumi ) this is still not ideal for linear rail mounting, but for hobby builds, this will help to you build a better machine
