Metalsculptingben Posted July 2, 2015 Share Posted July 2, 2015 Recently while using my 100# LG my treadle has pushed all the way past the normal point and fallen to the ground. It is like it loses back pressure and pushes past the normal point and I have to stop using the hammer. Can anyone explain what is going on?

ThomasPowers Posted July 2, 2015 Share Posted July 2, 2015 is your system stock or has it been modified sometime these last 100 years? What are your clutch blocks like? Pictures would be a big help! Quote Link to comment Share on other sites More sharing options...
Frosty Posted July 2, 2015 Share Posted July 2, 2015 We have to have pics. Unjammed ready to work and cammed over or jammed or whatever. Shots of the clutch and clutch arm in both positions. A text description isn't going to do it at all.Frosty The Lucky. Quote Link to comment Share on other sites More sharing options...
Judson Yaggy Posted July 2, 2015 Share Posted July 2, 2015 Checking the linkage from treadle to clutch is so simple that you must have done that or you would have mentioned it. LG's have very light easily damaged linkage rods between the two. You know that there is supposed to be a return spring on the clutch yoke?How smooth does the spider slide on the main shaft? If it's sticky there could be several sources of the problem. Most probably is that a mechanical hammer should be DRIPPING with oil. Oil every point before use and every hour during heavy use. Yes it's messy, yes it throws oil all over, neat freaks hate machines that drip oil, but that's how they were made to run.Bottom line we need more info.

Metalsculptingben Posted July 7, 2015 Author Share Posted July 7, 2015 As I am re-reading Richard R. Kern's book, it seems to be a problem with my sliding friction pulley. Does anyone else think that this would be a good place for me to start? Quote Link to comment Share on other sites More sharing options...
Frosty Posted July 7, 2015 Share Posted July 7, 2015 Did you put a few drops of oil on clutch contact surfaces? Just a FEW drops makes a big difference. Too many makes a big difference too just not a good one.Frosty The Lucky. Quote Link to comment Share on other sites More sharing options...
Metalsculptingben Posted July 7, 2015 Author Share Posted July 7, 2015 Yeah, I have DEFINITELY found out that too many is bad. Quote Link to comment Share on other sites More sharing options...
Metalsculptingben Posted July 7, 2015 Author Share Posted July 7, 2015 "Three items need to be looked at on the friction pulley. Generally only one is in bad shape. The first is the center bearing babbitt that lines the pulley. The constant pull of the belt and rubbing on the shaft have probably worn the hole oversize causing a significant rattle or vibration to be present. An oversize hole will also affect the clutch action." This is a quote from Kern. I am leaning towards this because sometimes I get a rattle that comes and goes as well.

Bob S Posted August 12, 2015 Share Posted August 12, 2015 try shimming your clutch blocks out a bit. I cut up a coke can for shims. it doesn't take much to make a difference. Quote Link to comment Share on other sites More sharing options...
