New build with recycled parts on a ridiculous budget 120cm*60cm work area

[Desertboy]

Dilemma 25mm supported rail with 4 bearings for the bottom axis or 15mm Original HIWIN with 4 carriages?

I now have the rail and then some lol ;)

Some nutter just bought a lot of rail and 40 carriages lol.

proper linear rail will always win imo... 15mm is a slightly awkward size in some regards but more than strong enough for any loads your machine will impart.

"but more than strong enough for any loads your machine will impart." that's all I need to hear ;)

The big PITA is I need 4mm T nuts like 90 of them lol at £3.60 a pack of 10, gutted because I have a bucket of 6mm T nuts somewhere :(

But now I can do Hiwin for the z axis as well. So Real Hiwin's on the bottom axis and Z and clone Hiwin's on the gantry a significant upgrade from the original plan but need to seriously think about how to build this properly. I'm taking my time but I'm getting there and hopefully with a hell of a lot better than an xcarve/shapeoko at less than their cost ;)

Not sure what to do with the other 32 carriages and rail but when I get my machine working I might just turn them all into Z axis's to flog (Add 1605 ballscrew of course) or maybe make some extra large 3d printers to sell.

Be nice to turn the Hiwin's I don't use into cash but probably keep a spare set in case.

Think I got 200 M5 for about £7 off ali express.

I was looking Lee but 30-40 days shipping time is just a little too long but would cost me ~£10 now for 100 M4 45 series T nuts KJN will cost ~£30 but I can pick up today (KJN is 4 miles from my work). I need to go KJN anyway to cut some more extrusion for the bed and they are going to drill/counterbore the extrusion I'm making the frame from. So I can bolt it together rather than use corners which is cheaper and stronger.

Humm sounds good plan, I remember thinking at the time I should order an assortment and bang them on ebay, the price for T nuts is ridiculous in this country/online.

When I finally finish my build I'm going to order 100 of each type for the 45 series extrusion for stock so I won't ever have to pay stupid prices again lol.

When I finish my machine I will have used nearly all my extrusion up so need to go on a pikey mission round the scrap yards to see what I can find ;)

Or just buy that machine I linked to if you don't first lol.
