Well not at all what I was expecting! I was talking to a friend about a build and the conversation has ended up with me adopting a partially completed build.
The machine was started as a project by a precision engineer friend and has been abandoned because of lack of time and his moving overseas for work... I still find it hard to believe he is allowing me to play with it.
Not much detail yet, I am still waiting for the original drawings so I know what the partially finished parts are for and what machining is still needed...but collected a few bits last week.... probably 350kg of them...
A pallet full of parts, some machined, some partially machined and some waterjetted.... the visible ballscrews are x axis and 32mm!!!

30mm hiwin x rails, 20mm for y &Z
most of the frame is 30mm aluminium... gantry is extrusion, sixes to follow
everything except the BOB in the electrics... servos and controlers etc...
2kw watercooled spindle
extruded aluminium table
Hoping to start work on it next week... far sooner than I would have chosen and still far too many basics to learn.. but we will have some fun along the way

And I thought Christmas was in December!!! Good luck with the rest of it. G.
By the sound of those parts it's going to be big and a beast when completed, very good deal.Spelling mistakes are not intentional, I only seem to see them some time after I've posted
Unfortunately I am building it for them... but good experience, and I will be able to use it... I hate to think what it cost so far as they are genuine hiwin and quality screws...oh, and I get paid pocket money too
I think it is about 2 by 1.5m "externally "

Got a little bit done this week, finding it helping with my rehabilitation as I need to use both hands for most of it
28 m16x50 holes tapped, 48 m8 tapped holes for the rails, all by hand as the company that did the original machining "forgot"... thanks for that
test assembly... I now know the approximate size is 2m x 1.1m between rails, and first problem... one of the cross rails is drilled about 2mm out, still thinking on how to best fix that, any suggestions gratefully recieved
nice chunky assembly, 160x30mm plate
The cross rail being drilled about 2mm out- if I understand correctly then I think you need to slot the through hole. If you don't have a mill then you may be able to use a router and carbide bit or pillar drill with counterbore bit plus some filing.

What about filling the holes with stuff then drill new holes.

I would worry doing it that way eddy, as the new hole would mainly be in the filler... and is 50mm deep
only alternative is to drill out to about 24mm tap & plug, pin it and then redrill & tap.... but holding this vertically to drill will be a right pain.
think it will end up on the inside and ream holes to suit in the side rails
