Steel/Aluminium design/build, sorta smallish, cuts ali hopefully

[mart154]

Im near Stowmarket.

About the sides and rear end. I plan to fill the sides/rear in with some MDF to control dust a bit better and I actually hope it'll make it a good bit stronger from there as well. With all the triangulation and say ~15mm MDF it should be pretty strong. Bear in mind that the straight legs are only 250mm long.


As for the gantry and Z carrier, the gap should be 42mm. Thats 43mm high ball nut carrier sunken into the plate 3mm and 2mm for good old air. I have to check the drawing. There might be a horrible mistake there somewhere.

I'm not really fond of the idea of cutting a 120mm box section apart to fit the lead screw in there... and then starting to strengthen it :)
As I have understood it would be best to keep the lead screw as close to the Z as possible to minimize leverage?

I might mount some little brushes on the ball screw to keep it clean when this comes an issue. Someone has done it on my Bridgeport and seems to work pretty good.

Edit: oh, about the base and those 20mm box sections there. Base is going to be covered with 20mm ali plate. Should be plenty strong then?
