New and in need of wisdom

[Washout]

Thanks Jonathan

I have been thinking about a second ballscrew on X, having read a few posts. I understand a timing belt arrangement and tensioner of some description is the way to go or should it be chain driven?

If I can squeeze it in budget I'll put that on, as the gantry isn't going to be light I expect and spreading/equalising the load on it sounds sensible.

The steel work would be small parts and yeah probably for a different machine.

BTW - I've been looking at mills, trying to find something suitable to cut "dovetails" into an aluminium recess that a bevel edged 3mm plate can slot into - any idea what I would need to do that?

Cheers

You need a dovetail cutter, but depends how wide/deep the slot is as to what size to buy. Something like this: http://www.ebay.co.uk/itm/16mm-x-45-...-/120938840568
