  1. Cheers guys. When measuring the belt to order a bespoke length, do you measure one side or the centreline or what? Won't make a big difference I guess but if there is a right way I'd like to know.

    You build it then you get a piece of string and rap around pulleys and take to belt place and say I want one that long.!! (or then measure it's length.)

    Very nice as always Joe. Great idea on the spacer plates to save pocketing the ball screw BK mounts although it does push the spindle further out slightly.

    Hi and welcome to the forum it would be better to start your own thread so as to keep all the questions you might have in one place.
    Have you built a machine before? and have you decided what you need to cut?
    Why not put a design up of what you would like to do. Good luck with the build.

  10. I have finally levelled the frame as best I can - in its "final" position. I decided to tack weld the beams which will support the x rails (now I know they are as parallel as they ever will be) prior to pouring the epoxy and most significantly I have started to make the mdf channels in which to pour it.
    I still need to grind the mill scale of the top surface and for the weather to warm up! Click image for larger version.

  11. Btw I have decided on 1no 30mm wide bridge and the channels for the rails will be 40mm wide (for 20mm rails) I hope this will be wide enough to avoid meniscus problems - I'm trying to get the most out of my tin of west system!

    Watch for shrinkage at the ends of the rails, mine were slightly lower at the home ends...dunno why! Also double and triple check the seal between the MDF moat and your rails, leaks are a bugger to stop! If possible line the MDF with packing tape as it'll make getting them off so much easier...much less work with a file :)
