I imagine there is routine annual maintenance on machines in pro shops. I might get lucky and the shop will have replaced the bearings already in the last few years. Taking apart that arbor assembly and hammering on and off bearings is the semi-daunting task at hand. Swapping the motor and belts seems easy with two guys. Is there a fail safe way to test arbor bearings? If I didnt have to replace those, this would be a much easier process.
#DELTA UNISAW MOTOR UPGRADE#
Also subtract what I am selling my contractor saw for, and I am pretty excited about the saw upgrade for a few hundred bucks. Then, if I can get lucky and sell the uni-guard that would only sweeten the deal. By replacing the motor, switch, belts, and bearings it looks like I am going to be at exactly $800 for a rehabbed machine. It's a semi-complex situation that you all are keeping me honest on. I dont feel like you guys are being nay sayers at all. This motor has the 3 belt pulley on it to, so I am pretty confident that it is a match for the 3 phase machine. I might be wrong, but from what I have read while searching, you can use the same right tilt motor on all unisaws from the 40s till about 2008 when they released the newest design. It has sat in his shop for 10 years, and hes been trying to sell it for a few months I think. This shop then went out of business and the person I am swapping with purchased the unused motor. Apparently some amish man purchased a unisaw, but didnt want the electric motor, so the shop kept it. Yep, the new motor is actually a delta branded motor. Also, how hard of a task is it to replace the arbor bearings on this saw? I figured I should replace those and the belts when I swap motors. I was with a local woodworker 2 months ago who was bitching about finding parts for his PM66, so I expect to experience part issues with any used cabinet saw.Ĭan the three phase switch be used with a single phase motor? That is one potential cost I havent factored int. Im assuming this one will tide me over for the next 3-5 years, and that I shouldnt expect any mechanical issues at all over that time frame. Im going in with the impression that this saw actually isnt that old considering what it was made for. What would potentially break on me that I would be screwed over? If Im starting with a new motor and belts/bearings are easy to come by, what else could go wrong? I dont know a ton about internal workings of saws to fathom a guess. $500 from what I have seen will buy you an ancient rockwell unisaw from the 40s or 50s. Ive never seen a single phase cabinet saw for under $1000, let alone $500. I know when all the "i need a saw for $500" threads pop up everybody tells the guy to go get a used cabinet saw. For all intents and purposes, I was under the impression this was a screaming deal. So, I am looking at roughly $600ish for a brand new motored 20 year old saw. I planned on selling the uniguard if I can as well, because I have an excalibur guard. Looks like the unisaw with bies fence and uniguard is going to be $500. I worked a deal with another guy to swap him the used 5hp 3 phase motor for a new 3hp single phase motor and $200. This is not intended to be comprehensive or even to sway you, but rather is an attempt to help frame some of the other issues.Ĭripes, you guys have me really second guessing this purchase now. This does not scare me off of everything, but I paid for a new saw recently because I saw money going down a hole with an older saw. You need to weigh the fact that neither saw will carry a warranty anymore, so any change you make that causes a problem is yours to fix. The tool setup can also become its own hobby. I won't poo-poo anyone who wants to tinker with VFD, but that ends up becoming a hobby of its own in many cases. The problem is that my small lot does not support the space needed for these tools that are made to work hard and generally have a larger foot print. I could get "cheap" used three phase equipment all year round. I live in a commercially rich environment. I could likely get service for the cost of a dedicated transformer (since my neighbors would not have a reason to share.) I would never do that here. There is big industry just across the tracks. I have three phases on poles in my back yard. A quality and properly engineered conversion drive or even three phase service may be worth it if you have a commercial atmosphere to draw from. I think this is a law of diminishing returns.
