re: Designing a mobile cart.

I will say, unless you’re going to somewhat anchor the cart, or the hose coming off it, their stock 4” hose is heavy and not very flexible. Of course this helps maintain pressure so it’s appropriate but, as you move it around, you’ll translate a fair amount of torque to the machine and the cart. I doubt it’ll damage anything, but it could make the tippy issue a bigger one to consider. I use a (too) long section of that hose in my overhead. I hung some brackets in the rafters and it lives curled up there, coming off a high-mounted gate. I grab the end and pull it down to attach to my planer and jointer when needed. I’ve bent two fairly sturdy ‘L’ brackets pulling on it. Like I said, heavy and stiff…

No bad mouthing the hose at all, it’s awesome, but it’s a consideration for your overall plan….

Actually, the more I’m writing this, maybe you want more freedom of movement in the cart to allow for an easier swivel if torque is applied via the hose? Just talking this out, but what about some 4” (6”??) castors, front and back, or something with a high degree of movement?
