I looked quite seriously at the routakit HD, but the cost of getting it sent to Australia was quite ridiculous.
I only want something wide enough to fit a 4’ wide sheet. It would really make it useful for small production runs!
I’m thinking I’ll join the SO3 & XXL gantry, make the base out of 1/2" steel or 3/4" aluminium with an HDPE wasteboard.
If the extrusions are relatively consistent in size I think I’ll get an aluminium block machined to fit between the two extrusions, maybe 6" long, then run some bolts through it.
