Thread: Aluminium CNC log.
I genuinely didn't realize that they had more then 1 page. I thought their biggist was 20x40! I didn't even bother looking for page numbers!
I can get away with using 6"x3/8"x... it's £15 for 1000mm so it should be more then enough. any metal above this size gets very expensive very fast!
I'm going to have to file the supports for the rail to allow the screw supports to be placed. I can live with that.
Box/rectangular section would be stronger if you can find a bit the right size.
I think Chip used the 6"x1/2" for his gantry ... it was definitely something close to that.
The 6 Inch stuff will be 10mm to thin. it's either get something 10mm wider or knock 40mm off my cutting area!
That's annoying as the next size up is 10" then 12"... if you decide to get the bigger size which has to be in a 2m length (I phoned them and they said they don't sell smaller) I might buy the spare from you. For a good price :lol:.
the only way I could make it work with 6" would be to mount the supported rails on the very edge of the alu and filed down the screw supports.
I'm talking 1mm from the edge of the hole to the side of the alu.
If i went for 10" it would be silly as my Z axis would be so wide it would be worse then using the 6" with the rails mounted properly!
Can you drop down to 6" x 3/8"?
A lot more cost effective.

This is wgat I'm talking about:
I was planning on getting the 4 axis one from Zapp but he was out of stock. I'm sure this one will do just as well. I'll be using DIYCNC drivers as well.
how is this for Z and y?
no snide remarks about it floating! :)
I'm not sure on the exact spindle size so it is mainly guess work :(
