I BOUGHT A 3 TON PRESS FROM ENCO WHEN THEY HAD THEM ON SALE .
THIS WAS A BARGAIN BECAUSE I ALSO GOT THE FREE DELIVERY .

ONCE I GOT IT , I WAS NOT IMPRESSED WITH IT's ABILITES
FORTUNATELY , THERE IS ALWAYS ROOM FOR IMPROVEMENT

THE RATCHET DOES GIVE YOU MORE CHOICES OF WHERE TO PULL THE LEVER
BUT DOES NOTHING TO INCREASE YOUR MECHANICAL ADVANTAGE .

I FOUND A WAY TO IMPROVE MECHANICAL ADVANTAGE WITH SOME
GOOD OLD FASHIONED GEARING .

THERE ARE THREE GEARS . THEY ARE 1.5" WIDE TO CARRY INCREASED LOADS .
THE 50 TOOTH MAIN GEAR IS KEYED TO THE SHAFT OF THE PRESS .
THE 50 TOOTH INTERMEDIATE GEAR REVERSES THE ROTATION .
THE 20 TOOTH PINION INCREASES YOUR EFFORT BY 2 1/2 TIMES !

THERE ARE TWO 1/4" STEEL PLATES WITH THE GEARS IN BETWEEN LIKE A CLOCK .
EACH SHAFT IS DRILLED & CROSS DRILLED FOR EASY GREASING & TAPPED FOR A ZERK .

THE PRIMARY PLATE MUST BE FIXED ROTATIONALLY FOR THE GEARING TO WORK
SO I DRILLED & TAPPED 12 M6 HOLES IN THE CAST IRON & USED GRADE 10.9
FLATHEAD SCREWS .THERE , THAT OUGHTA' DO IT .

THE LEVER IS 3/4 STAINLESS AND PARKS PAST VERTICAL SO NO COUNTERWEIGHT IS NEEDED .
IT IS TIED TO THE PINION GEAR WITH A SQUARE PIN ON EACH END .

THE PINION HAS HAD 4 TEETH REMOVED SO WHEN IT IS IN THE PARKED POSITION ,
THE OTHER TWO GEARS CAN ROTATE TO ANY POSITION .
THE LEVER HAS 180° OF MOTION SOME OF THIS IS LOST IN THE ENGAGEMENT PROCESS .

I WILL USE THIS MAINLY FOR INSTALLING PEMS , PRESSING BEARINGS AND
BROACHING KEYS IN PULLEYS AND GEARS .

Nice work! So how much ram travel is produced by 180 degrees of lever movement?

THE RAM MOVES ABOUT AN INCH WITH A FULL STROKE .
 
So if you are doubling your force applied will the Cast Iron frame stand up to 6 tons ?
I have the same press and got it under the same deal. Only needed to use a short cheater bar
once and was a bit leary of over stressing it.

THIS IS MORE ABOUT HALVING THE EFFORT THAN DOUBLING THE FORCE .
THE FRAME IS NO STRONGER .

I RECENTLY BROACHED A 3/8" KEY AND WORKED UP QUITE A SWEAT .
I WAS QUITE THANKFUL TO HAVE A 2.5/1 RATIO ON MY SIDE !
 
Very impressive. I really like seeing work completed which is "clean and finished." Although I strive for that bar, I tend to reach a point and tell myself... This is good enough. I have reached the conclusion that I am a very utilitarian type of person. If it works and ain't broke, I'm golden at heart.
But...Like I said, I love seeing others finished craftsmanship. Your press is in that class IMO. Well done.
