Just for discussion. It seems that heavy duty grounding casters are pretty popular in the US to enable machine movement in a small shop. Over here it's fairly common to use what we call a pallet truck: e.g. http://www.vestilmfg.com/products/mh...lowprofile.htm (not sure if it goes by that name with you guys)
I've gone that route, and at this early stage find it works very well - it's very flexible, means that I have the ability to shift all sorts of heavy loads, and at about €250 for one these days is not too expensive.
My machines are all Hammer (spindle moulder, panel saw and planer thicknesser), it was much cheaper than buying OEM wheel sets. You do need a low profile model to get under the Hammer machines.
A big bandsaw is next on the list, it's not really set up to suit the truck as you can't get the forks under it. The provisional plan though is to build a wooden sub base with leveling feet and openings for the forks - i think I'll want to raise the table level anyway, and may also raise the Hammer machines a bit.
I'm hoping that the Hammer machines (especially the panel saw) won't need moving once the positions are optimised, as it's probably a recipe to cause alignment problems with the sliding table. The bandsaw probably will need to be moved fairly regularly to make clearance for longer ripping type jobs...
