Phatdaddy Report post Posted March 8, 2013 I see that TechSew offers a speed reducer addon that wasn't available as an option a year ago when I purchased mine. I've been in contact with them and they will sell it with the belts needed. I was curious, have any of you have purchased one after the fact and added it yourself? Did you notice a big difference? Was it reasonably easy to upgrade your existing table? Thanks for any info. Kevin Quote Share this post Link to post Share on other sites
Greystone Report post Posted March 8, 2013 Thanks I'm looking, to add a speed reducer, after the fact to my machine, interested in how the table mods and cutting or machine position are affected db Quote Share this post Link to post Share on other sites
Wizcrafts Report post Posted March 8, 2013 The reducer should be fitted as directly inline, laterally and vertically, with the machine's pulley as possible. However, the lateral position is more important, to minimize shake from an off-center pulley. You will probably have to relocate your bobbin winder assembly so it makes contact with the new belt position. Quote Share this post Link to post Share on other sites
Art Report post Posted March 9, 2013 Just replace your current motor with a reduction motor. I think Bob sells them. You might need a new belt if the pully size changes. Should be a bolt for bolt, hole to hole replacement. Art Quote Share this post Link to post Share on other sites
billymac814 Report post Posted March 9, 2013 I've put a speed reducer on my patcher after the fact. It was a fairly simple procedure if your able to drill a few holes. You'll have to move your motor and just line everything up. I prefer a seperate speed reducer rather than the gear reduction ones personally plus a speed reducer and the belts are cheaper if you already have a servo. Of course you could sell your servo and recoup some of that money if you went with the gear reduction servo. I seem to get a little more belt slippage from the gear reduction servo than I do with the servo/ speed reducer combination. To be fair though I haven't tried comparing the two on the same machine so it could be just the differences in machines. Quote Share this post Link to post Share on other sites
Northmount Report post Posted March 10, 2013 I replaced the servo on my 2700 with the SewSlow gear reduction unit from Bob. It helped a lot, but still wasn't slow enough for me. At the slowest speed, it couldn't punch through hard 8 - 10 oz leather. Added pulley speed reducer as well. Now I can go as slow as 3 seconds per stitch and still have the torque needed to punch through the same leather. Flat out is now a little slow with the servo pot turned up as fast as it will go, but it's fine for me. No trouble going around the point of a belt, just have to be a little patient going down the side. Tom Quote Share this post Link to post Share on other sites
Phatdaddy Report post Posted March 13, 2013 Sorry, I was away for the weekend with the kids being on March Break. This is good news, I think this will help greatly and I will gain the confidence to use my machine. Once I can slow it down and maintain/gain some power at slow slow speeds then hopefully I'll be able to get it adjusted properly also...but that will be another story. As always, I appreciate and value all of the info offered here. Kevin Quote Share this post Link to post Share on other sites
