October 2, 201213 yr It's been sitting 25 years in a dry garage and is ready for a makeover and a motor. Picked it up for a decent price and I plan to flip it after I've had my fun.....It won't take much though, It's in real nice shape for an older one... LG ser # 2588
October 2, 201213 yr Looks to be in good shape should be easy to clean up, should make somebody a nice little hammer.
October 3, 201213 yr Author The good news; the ways, front and back are crisp, the same with the hammer V's and the upper die receiver is nice..... The soso news is the bearings both clutch and mains need repored, the bottom die receiver base needs to be built up and re surfaced.......And the bad is the links need replaced and the ram needs an interior rebuild where the T's ride so Sid will happily relieve me of about $300....not too bad..... :mellow: I plan to cut the spokes out of pulley (lg3) and machine it (even though I'm not qualified) to heat shrink onto the idler drum so it will be larger in diamiter making it easier to attain the desired speed and the belt won't ride on the inner flat surface........I reckon the shaft was 1.625 new and now it's 1.610 (front and back) do I need to machine a dummy shaft to 1.610 to re pour the mains? Any pointers appreciated....mb
October 3, 201213 yr I plan to cut the spokes out of pulley (lg3) and machine it (even though I'm not qualified) Ha! only part 1 of a rebuild is available but it may be of some help.http://www.anvilmag....smith/011f2.htm If I remember right I recall that Sid had some tooling available for rent or ? to help with pouring new mains.
October 4, 201213 yr I think you can cast the babbitt around your original shaft provided it is not worn out-of-round. That's the way the bearings on my 25 pounder were done. -Don S
October 4, 201213 yr Author Thanks for the link Bob. Don, the shaft seems to be OOR not more than about .009 max here and there. I like the dummy shaft method but may try it with the shaft since I can easily lift it strait up and down easily with my hoist.... What is the target + - bpm on these and I believe a 1hp minimum motor is the correct choice, right? Waiting now for Sid to do his thing on the ram toggle link seats and the new links....Couldn't see those through the crud otherwise I would have stood firm on a lower offer but $300 + shipping won't break the bank.....
October 5, 201213 yr Author A long lost buddy of mine showed up out of the blue yesterday after 25 years and happened to have a copy of R Kern's book ''The Little Giant Power Hammer'' which he droped off today.... B) ..... The pic shows the old spoked pully with the innards removed and one of the sheaves sliced off as well. The single sheave on top of the idler is ready to be bored slightly under the idler OD and shrunk onto it. I have a 2.5'' cast iron motor pully that will give me an estimated 383 BPM or if I want to lower that I'll need to buy a smaller machined steel pully. The book sez 375 BPM but I think the 2.5'' will be fine....any thoughts?.....
October 5, 201213 yr Mine runs on a 2.5 cast iron pulley. I use 2 'B' vee belts tho I think 1 would be fine. My belts run on the outside surface of the idler. On my hammer the idler/clutch is to the rear of the machine. I worked out the speed years ago when I set it up. Think it was in the 350 rpm range. My motor is mounted low on the right side. Will take pictures tomorrow if you want.

Will take pictures tomorrow if you want. Thanks I'd love to see your pix...... If I ran a 2.5'' pulley with a 10'' idler I'd be at 483 BPM, no buneo. The 11.375'' sheave mounted on the idler is almost like a jackshaft only allot less labor intensive and cheaper. I've done this on a Perfect ages ago and it worked fine. Just one hitch with the LG is the idler moves allot father to engage the clutch where the Perfect maybe moves maybe 1/16''. I'm hoping to keep the idler travel to a minium so it doesn't deflect the belt too much.
October 5, 201213 yr online rpm calculator at link below. mine is 331 rpm. http://www.temecularodrun.com/ref/rpm_calc.asp
October 6, 201213 yr Would you ever consider sheet metal work under one? Thumbnail die... I would be interested about learning more about this? Thanks!
October 7, 201213 yr Author Would you ever consider sheet metal work under one? Thumbnail die... Would I? Probly not, but I'm sure it could be done. I know what thumbnail dies look like and they're supposed the shrink the metal. How this is accomplished by hammering and what it looks like after that is a mystery to me.........
October 7, 201213 yr I am a little uncomfortable with the shaft ,009 out of round. A lathe with a tool post grinder will cure that.
October 7, 201213 yr make a new shaft and make it longer so you can mount the pulley and clutch outside the frame at the back. That will make it much eaiser to install and service the clutch and you don't have to take the shaft out to change the belt. use the new shaft to pour the bearings before you assemble the fly wheel
October 7, 201213 yr Author I miced it again so I could rotate the mic instead opening and closing the tool here and there on the shaft and it came up good. Not even .003 out of round.... :wub: ....I like your idea Peacock but i'm gonna have to pass on that one this time, I'm opting for a Browning ''Griptwist'' belt which can be parted so it won't need to have the shaft removed to change the belt.
October 9, 201213 yr Author Shrink to fit V belt conversion completed......Come on Sid, I need them parts........
November 1, 201213 yr Author Getting close.......What looked like an easy flip will top out at around 40 hrs and hundreds of $.....Live and learn..... B)
November 2, 201213 yr Author What's the trim color going to be? Frosty the luckyTrim color.... :angry:....I gots to show you no stinking trim color!! I was thinking of some gay yellow pinstriping though.... :wub: .....and yellow of course for the foot treadle....... The spring attachment that pulls the treadle up and transfers the energy to the clutch arm by pushing it up through a spindley 5/16'' rod just seemed bass ackwards to me so I aranged differently as shown. The old arangment also multiplies whatever slop there is in the linkage because it pushed up and pulled down, anyway I like this better and I don't have to fight assembling it.....Think I'll go to a stouter spring though
November 6, 201213 yr Author DONE! After flailing with this little XXXXXXX for longer than I thought possible I have a better understanding of why Sid gets what he gets for his rebuilt hammers.
