Members Nandy Posted June 27, 2015 Author Members Report Posted June 27, 2015 I looked at the bronze bushings but I could not find specs as far as rpm and such, that is why I am a bit shy about them. For what is worth, I did see another member here that just slapped the 2 pulleys together and use a bolt for a shaft and did not even use a bushing (at least it appeared to me that way)... not sure how is that contraption is still working. Is that picture of your reducer and do you have a picture of the other side? Quote
Members SARK9 Posted June 27, 2015 Members Report Posted June 27, 2015 Here is a picture of one of the ball bearing reducers I made, before installation, showing the mount and adjustment areas. The bronze sleeved ones are just like it, essentially. -DC Quote Machines: Juki LU-563, Consew 206-RB5, Singer 20U33, Pfaff 481, Mitsubishi CU-865-22, Consew 29B, Rebadged Juki LU-562, Mitsubishi LS2-180, Seiko SK-6, Juki LG-158-1

One picture shows parts separated the other the way ti would be working. the pulleys have allen screws to fix it to shaft along with 3/16 woodruff key, on the other side of the pillow blocks there is a collar that locks shaft so it stays in place. All parts can be purchased on ebay. This setup is using 3/4" shaft. Quote

Uwe Posted June 28, 2015 Report Posted June 28, 2015 (edited) SARK9 - those are super nice speed reducers you made - well done! I made a speed reducer similar to DannyGray for my Adler 205. It works well and no machining required, but the SARK9 version looks way nicer and is much more compact and easier to adjust. Alas, my particular configuration of the stand did not lend itself to using the compact version the machine came with when I switched to a servo motor. Here are some pictures of my speed reducer, made from parts sourced on Amazon.com and my local Home Depot: Edited June 28, 2015 by Uwe Quote Uwe (pronounced "OOH-vuh" ) Links: Videos

Members wydfuqnopn Posted November 6, 2018 Members Report Posted November 6, 2018 (edited) https://www.walmart.com/ip/Grizzly-G5436-Single-V-Groove-Pulley-6-Pitch-Dia-1-2-Bore/134318402 this is the one I bought. but I am replacing the stock hand pulley on the machine with this one. it is almost twice as big and coupled with a 50mm replacement on the motor I think it will work. will keep you posted on the results.

Members chrisash Posted November 6, 2018 Members Report Posted November 6, 2018 (edited) Remember a old worktop standing drill, it had about 6 sets of pullies in pairs of various sizes where you moved the belt up or down and have 6 speeds to play with, maybe you guys are thinking to small with just one pair Edited November 6, 2018 by chrisash Quote Mi omputer is ot ood at speeling , it's not me
