Description: This robust extra short power coupler is being offered for Shopsmith owners that have a need for a very short coupler. The coupler has an overall length of less than 1.20 inches versus the OEM coupler that is 5 inches long. This coupler will allow the hub of the accessory to touch the drive hub. It is a molded part as of April 2022, replacing the previous 3d printed part. The molded part is made of a glass filled polypropylene. My torque testing shows a strength of 40 ft-lb. Wear should be much improved over the previous ABS part due to the glass filler. Keep in mind the shaft alignments need to be much closer since the length is very short. Misalignment causes asymmetrical loading at best and interference at its worse. Misalignment will likely cause premature failure due to wear. The belt sander accessory is the hardest on my 3D printed couplers. There are a number of potential issues. First is centering alignment between the headstock and beltsander, it needs to be very good, preferably less than 1/16 of an inch, also the length of the dowel needs to be on the longer end, probably 1.5X the OEM coupler length. If not aligned there will be plastic debris from internal grinding. Another possible issue is shaft runout (slightly bend of shaft) on the beltsander, as an accessory sometimes things get accidently bent, which would exhibit itself as grinding too. Aligning the shafts isn't difficult but will take several minutes to an hour depending on how rusty things are. Both vertical and horizontal centering can be adjusted. Another Belt sander concern is belt tension, especially if the rubber roller has age hardened. People tend to tension it greater, which dramatically increases the torque load, this might be evident by the headstock struggling on start up. https://www.youtube.com/watch?v=hEg36ctsjWc https://www.youtube.com/watch?v=F22xO0QOZbMhttps://www.youtube.com/watch?v=UL4M1D6Ie1c (if the link doesn't work search for: power couplers in use ) I am liable only to the extent of the purchase price of this part.
