Router bed - What's best???

[John S]

Steve,
What about fabricating a bed up out of tooling plate, This is high strength alloy that has been ground flat.
One large plate of say 12mm with strips of say 6mm 90mm wide with an 8mm strip on top of that 100 mm wide.
Viewed from the end this will make a tee slot when mated up with one at the side.
CSK Allen screw thru the top two into the bed plate will hold it all together.

This way you get the exact bed layout you require and are not held to any extrusion layout.

Try ASC Metals at Lincoln, they stock tooling plate and will cut it to any size on their big bed saw and it a good cut and square, a bit of draw filing is all that's needed, no machining other than drilling and tapping.

OK, as promised a couple of images of my design so far.....

Its still at the design stage so if anyone wants to throw in there two penneth then go-ahead!



Current bed size is 1000 x 600 but unless I go along John's route then I can see it changing.

May have found another supplier for 20mm extruded bed plate, should have quote tomorrow so I will let you know what the price is like. I know it won't be cheap and if I go for it then I may have to increase the bed width to 750 so that i can just slot it in.

All the linear slides are 20mm THK's so not too worried about racking with one screw in the middle but I may be wrong.

Screws are 16mm x 5 ballscrews on all axis

Steppers are 23 size 3.1 Nm
