Work scrap bin router build

[Vic66]

Hi all

I'd be interested in any comments about my ex-work scrap router design, I've not got a lot of cash to spend and am trying to use parts sourced cheaply through work, so the build is based around the parts I can get, I want to cut parts to length at work then assemble them at home in my workshop, keeping it a simple bolt together assembly. I frequently use a local laser cutting company at work and they don't mind cutting small batches of parts for me for cash so I've used quite a few 6mm ally laser cut parts in the design.

So far I've managed to get a pre machined 16mm ballscrew with a thread length of 1360mm and 12 Hepco dual V bearings, so I'm leaning towards a similar system used on Joes hybrid machine using steel angle for the V bearings to run on, all the aluminium is standard section with some commercial vehicle ally bearers (£15 for a 2.5m length) for mounting the bearing runners on. I have a 16mm ballscrew for the Z axis, I was planning on buying cheap trapezoidal for the X axis hoping to upgrade later on.

I've pretty much finished the design and want to make a start on the build but I've got a bit of a dilema, I'm thinking that only having one drive on the Y axis might make the X axis carridge 'walk' up and down, and I'm thinking about using my 1360mm ballscrew for the X axis instead of the Y (gaining 200 or 300mm of travel on that axis) and using two trapezoidal rods and two steppers for the Y axis, the rods would run in the channels (see image 3) and I would remove the cross beam from underneath.

This would be my second router, I've built a Rockliffe fixed gantry prior to this and got hooked

Cheers
