Quoted from Murphdom:You can buy these at a place like Harbor Freight or Amazon. They are cheap but are only good for a hard surface. My machines are on a somewhat thick rug so I had cave and buy real pinskates. They are pricey but worth it. Those dolly’s still worked but it was hard to move the machine around. I just moved 7 machines across my house on the skates by myself with no issues[quoted image]
These area piece of shit and within minutes my machines bent and twisted 2 of them. I was so pissed off.
Unless you are on a perfect surface that cheap HF junk will buckle at the first obstruction!!! 
I ended up buying a Wico pincart because I was sick of sub-par junk.
Po skates work good if you have the legs on but if you are constantly putting legs on or off then a true cart will be the best bet
