just another plasma build and then some :)
on the plus side if i build it well i might be able to up the HP on the spindle later down the road? i have to see how the gantry does with cutting forces. But Haas does a machine like this milling part of mine and they only have the 1" aluminum for their table tops but their machines start at 120k so even with my modest attempt i am well under that price tag
i think once i add the extra steel and E.G. the last little bit of flex i am getting might go away. the rest of what i am seeing could be coming from my table part of the frame since it's not in a finished state just yet and has some improvements being made.
my hardner was on back order for my resin so i probably won't see those materials til next week sometime. i won't get to the forms for the E.G. until Saturday most likely so hopefully i can get that don'e by next weekend so i have the weekend to do the E.G.
it will take some time for that part i'm probably looking at 750 lbs of mixed material there. so another 650 lbs of aluminum should make for a machine around 3,000 lbs when i am done. ton of work but worth it i think
will be good to test the drives out to see how every thing works under power.

Do you think your castors will support all that weight? So roughly about 1370 kg for the table + your material your cutting.
Is it going to be a water table? Or downdraft? If water, what size will the pan be? Say a pan of 2400x1200x75 would hold 226 liters so about 226kg of water when full.
Just as a guide, a 2400x1200x10 sheet of mild steel grade 250 weights around 225kg.
So 1370kg can add up to around 1820kg pretty easily.

Yeah you probably should be right with eight castors.
I have some steel baskets in our workshop that get filled with pipe webbing for our trusses. I brought some castors for them that were rated at 250kg each and installed a castor in each corner of the basket. They failed in a couple of months in ways I would of never imagined. Replaced them with new castors rated at 500kg each and all is well. The baskets never get loaded about 750kg so I thought four 250kg castors would be fine.
