AVOR – a steel-framed medium-size router

[Neale]

Very simple. The linear bearing carriages are bolted to a 12mm aluminium plate with cap screws in counter-bored holes so that bolt heads are below the surface. In effect, I then have a linear bearing skate. The bearing carriages are aligned to the rails before being finally bolted up tight (just run the "skate" backwards and forwards a few times before tightening screws). The "feet" of the gantry sit on pads of epoxy paste for leveling (as described earlier) and are held in place by three bolts at each end of each foot. These go through the base of the foot box section into tapped holes in the aluminium plate. Two bolts are near the end of the foot and one further in, carefully positioned so that you can get more than 60deg swing with an allen key in order to tighten it.

Does that help?
