Ive been building cabinets/racks/storage for my tools and things for 8 years.
I usually get decent castors as it makes life easy.
For some reason, it took me over 5 years to realize if I didn't figure out a way to move my 22/44 drum sander in and out of shed easy enough, I may never use the thing again, which I haven't recently.
A few weeks ago, I finally decided, 320 lbs rated pneumatic castors were not doing the job because I constantly had to inflate them, for some reason they would deflate(well, not no reason, couldn't handle the weight.)I figured 4 of them should suffice, but as usual I was wrong. so the drum sander sat in back of the shed.
I purchased the highest rated blue castors at HF, yes, HF(I don't purchase much from them ever), 600 lbs each. wow.
Now I can move it in and out of the shed myself, it rolls so easy it even rolls over the grass easy enough.
I can get it in and out in under 5 minutes.
good news is Im using it again.
Been doing a run of boards between projects, and its very, very useful.
Don't ever skimp on the castors, EVER. Properly weighted decent castors will make your life so much better. Just some advice for the new people starting in with mobile cabinets.
spend the dough, get the best. always.
