What sort of clamps are there for that sort of set up ? or do you make your own ?. I suppose 10mm T slots ?

I try to buy everything on ebay for ease. What grade of Alu should I get for the bed ?

But you can use just about anything really...

There are quite a few examples of homemade ones on forums. 10mm should be fine.

6082 is generally the best value. Aluminium is really expensive on eBay. www.aluminiumwarehouse.com will be much cheaper, or I use Metal Stockists: ASC Metals Lincoln Ltd. - Metal stockholders for East Midlands/North of England as they're even cheaper...

Seeing all my rails are 25mm round (unsupported) do I really need to replace them with supported rails ? I see that most machines of this size only have 16 or 20mm supported rails.

Yes, if you are not satisfied with the current rigidity of the machine. Even 12mm supported is likely to be stronger than 25mm unsupported over a reasonable distance, but that doesn't meant you should use 12mm:

For much of history most people believed the earth was flat, but that didn't make it flat!

Wow, China again. After shipping plus import tax, do you think the prices would still be better ?

To England I'm certain they would be, so unless where you live the taxes are even more extortionate, it should be cheaper.

just for the record i've had to pay £21.50 to fedex a week after i got my deliveries from china, i'm not sure if it's that much due to the fact it come in 2 parcels

I have 45mmx45mm profiles with 10mm T slots. Please could someone point me towards an ebay link that sells the correct T Nuts and bolts for these rails for 45mm profiles. I think the rail bolts need to be M6.


FOUND THEM....thanks
