Don't forget to go through the registration process for your "Lifetime Warranty". I've used it once but only after using it almost around the clock for a week cutting 1 1/2" thick aluminum making router mounts, a backing plate for my 4th axis chuck, and a few other jigs & fixtures for my 2 Techno-Isel CNC's. BTW, I put a dial indicator on all 3 of my Rigid 2401's and found no measurable run-out using the original Rigid 1/4" collets and the same with the Think & Tinker precise 1/4" and 1/8" collets. Maybe I was just lucky, but 3 out of 3 tells me that they have pretty tight quality control! I have no interest in Rigid or Home Depot and have only recommended them because I was so happy with the tools that I wanted to share it with the cuemakers here. I've probably spent more on spindles over the years than most have invested in their CNC's. To find one that works so well at such a reasonable price point just blew me away! Oh, and to answer the question about the Wolfgang spindles. I've had 3 of them and and my only complaint was the lack of torque and being limited to 1/8" end mills. Wolfgang gave me excellent service and if I were only using it for inlay work, it does a fine job, but with the Rigid I can use 1/4" shanked router bits and do things like cut my "V" grooves on the CNC for short spliced cues and do the occasional jig making, and motorcycle parts cutting aluminum which would be out of the question with the Wolfgang.
