Review on 4 All Steel Swivel Plate Caster Wheels w Brake Lock - Heavy Duty High-Gauge Steel Gray (3" with Brake) by David Perez

I have a 50 year old Delta table saw that needs new rollers because it pivots around the frame - this system allows you to move the saw where you want and then a few Push lever to set it up so it doesn't roll. Retaining ring that must be a certain length and replacement is rare and expensive. The center hole is listed as 6mm, which is slightly smaller than the roller hole on the saw. The holes are not 1/4", they are 0.225" or about 30 thousandths too small. This required me to drill holes. Not a big deal, but I couldn't use nuts and bolts either, so I had to buy 1/4" bolts and locknuts. smooth shank, but you'll have to cut off about 1/2" after the nut threads on. Also, are the sides of the wheels where the hole is located is "cast" and very rough. the wheels roll easily. I sanded them with the side of the grinding wheel and at least smoothed them out, but a human doesn't need to do that. Also, the castings themselves not very good quality Hopefully they last - If so I can improve my rating.
