PowerPro Upgrade Thoughts
Posted: Tue Dec 06, 2011 12:59 pm
Here are my observations after finishing the PowerPro upgrade process on my 520 machine. When I unpacked the box I discovered the power supply part had one of the fins bent towards the others (see attached picture). There was only 1/16” space between the fins at the top. I called ShopSmith and Dave told me not to worry about the bent fin. I agree leaving it alone was better than trying to straighten it out and risk breaking it off. I just wanted confirmation before I installed the power supply. If there is an overheating problem later I’m sure ShopSmith will make it right. I just used scraps I had on hand as the “stage” and for the board the table legs push against to raise the way tubes to remove the headstock and install the motor. Being somewhat cheap I didn’t want to waste any materials making something for a single use.
The directions in the printed material say to turn the speed to SLOW and unplug the machine then turn the speed to FAST. On the DVD Jim McCann says turn the speed to FAST then unplug the machine. The instructions to turn to FAST then unplug the machine are better IMO. This makes it easy to remove the belt from the lower sheaves. You CAN turn the speed from slow to fast with the switch OFF and the machine unplugged but why take the extra step? When enlarging the hole in the motor pan for the new power cord Jim says to use a file to do the entire operation. I used increasingly larger drill bits to enlarge the hole by 1/32” increments until I got near the circle I drew on the motor pan using the template. That made it much faster (and less of a strain on my old arms – don’t want to use all of my elbow grease before I die!). This left just a small bit of cleanup to do with the file at the end of the process. Overall this was a pretty easy upgrade thanks to the excellent documentation provided by Shopsmith. The pictures could have been a bit higher quality but were adequate for the tasks to be accomplished. This upgrade is another example of quality workmanship and customer service from a great company. No wonder they have such loyalty from their customers – they earn it every day with the way they operate! THANKS SHOPSMITH.
