Bought a piece of 3 inch square aluminum tube for the gantry. Tried threading it to fasten the rails but the material is so soft it stripped while trying to power tap it, the treads wouldn't pull the quill down. Plan B, used nut serts, handy little devils.

Rails mounted with spacers between the beam and the rail.

Will build the plate for the carriage next to see if the two rail arrangement will be accurate enough.

Free advice is worth exactly what you payed for it.
