Members Hi Im Joe Posted July 12, 2014 Members Report Posted July 12, 2014 Hello guys and gals, My father-in-law has a co-worker who services sewing machines as a hobby. I got the adler 67 up and running. My main concern now is the speed it runs at. It's either hand cranked or just full bore insane. What are some cost effective ways to slow the thing down to a manageable level? Are there speed reducer's available? Are they worth the investment or should I just bite the bullet and buy a servo motor? Anybody have any DIY ideas as a stop gap measure while I get my funding in order to do it right? Thanks again so much for sharing your expertise with me! Joe Quote http://www.sevenhillsleather.com/
Contributing Member Ferg Posted July 12, 2014 Contributing Member Report Posted July 12, 2014 Jo, Just bite the bullet and buy a servo. You will pat yourself on the back every time you sew. ferg Quote
Members Hi Im Joe Posted July 12, 2014 Author Members Report Posted July 12, 2014 Yeah, I think that's my eventual plan. My budget is just non-existent right now. Quote http://www.sevenhillsleather.com/
Northmount Posted July 12, 2014 Report Posted July 12, 2014 Learn to slip the clutch. Takes some patience and practise. You can also do a search here for speed reducers and see what others have done to build there own ... If you are the handyman type. There are lots of posts here about various servo motors to. Look at comments by Wizcrafts. Tom Quote
Members Hi Im Joe Posted July 12, 2014 Author Members Report Posted July 12, 2014 Yeah I can use the clutch. It's really the only way to do any detail type work. Its hand cranked or full bore. I want to figure out a better way to control the speed for safety's sake. I don't want a slip of my foot to result in sewing through my hand. Quote http://www.sevenhillsleather.com/

Members catskin Posted July 12, 2014 Members Report Posted July 12, 2014 (edited) If you can find a REALLY OLD clothes dryer some of them have a perfect speed reducer on them in the back. The one I found is a 2" pully on the side of a 10" pulley It runs on bronze bushings but with a bit of oil once in a while mine has run for 20 plus years. And its still going. I use mine with a clutch and motor. Edited July 12, 2014 by catskin Quote

Trox Posted July 12, 2014 Report Posted July 12, 2014 Hi Joe, you could start with changing out your motor pulley to a smaller one. Try a two inch pulley, that will slow it down allot. A speed reducer costs from 90 to 150$, a cheap Chinese servo is the same and you do not need both. Never put any oil or fat on a clutch disk, then you will damage it totally. Technics to control clutch: Make sure the chain/rod from the pedal goes to the last hole on the motors pitman arm (more pedal travel and more control). Take your shoes for better pedal control and put your right hand on the machines hand wheel to brake and slow it down.

Members Hi Im Joe Posted July 12, 2014 Author Members Report Posted July 12, 2014 Thanks everyone! I have a lot to think about. Trox: I will adjust the pedal. I love going barefoot so taking my shoes off is the best news I've heard so far! The thing goes so fast I don't think I could brake it to slow it down. It would just keep on going like crazy. Maybe I am just afraid of it. But I don't think I could slow it down with my hand. Right now the most successful method is to slip the clutch and hand crank the wheel.
