I have one the virtual twin of that one but branded Ryobi and with a top speed of 3050 rpm. It was a gift from a neighbor. Here is a hint...if you extend the quill and feel play at the end while it is at the furthest distance down, make yourself some shims using .016" brass cut about 1/2 inch wide. Bend them in a square shape and work them down between the quill and the shaft collar at top (you'll see where the problem is). You may have to sand the final shim to get it right. I had to shim mine about .044" to remove all the slop. There is a fine line when you do this...a line where it won't stick but feels almost like it wants to. Grease it using disc wheel bearing grease. Mine is so wobble-free I can speed it up to the highest speed and use it as a simple mill with an end cutting bit and an x-y table. At first I thought the chuck was causing the trouble but the chuck turned out to only have a slight runout.
