not sure how that would wouk this is on a cammake a rod up and a lever further up saves you bending down

use the existing lever . take the ball off the end and fasten a hinge of sorts conected to the rod up over conected to a lever sticking out to operate just up and downnot sure how that would wouk this is on a cam
hum ill have a fiddle with it not sure it will will as easy as u make it sound but maybe I can picture ituse the existing lever . take the ball off the end and fasten a hinge of sorts conected to the rod up over conected to a lever sticking out to operate just up and down
Interesting stuff. Know sod-all about Lathes but I think I get the external lever/linkage idea.hum ill have a fiddle with it not sure it will will as easy as u make it sound but maybe I can picture it
sounds easy! will I get enough movement on the lever though? it moves through more than 180 degrees to drop-tension right nowInteresting stuff. Know sod-all about Lathes but I think I get the external lever/linkage idea.
- White ball exchanged for a pivot connected to vertical linkage bar with another pivot at the top.
- new horizontal bar connected to top link which then goes through a slot in the door/cover.
- door cover has 2 half-circle cups either side of the slot for a centre pivot for the protruding bar to sit in (so it's easy to remove the centre pivot & take off the slotted door/cover if you want access)
- put the white ball handle on the end of the protruding bar.
(Raising/Lowering the external handle operates linkage, which operates the lever you now operate directly).
(Make the door out of thick perspex & you can still see what's going in there maybe?)
Hmm... in theory it's all down to the leverage ratios and the length of the levers.sounds easy! will I get enough movement on the lever though? it moves through more than 180 degrees to drop-tension right now
it is all going to be a trial and error game I think.Hmm... in theory it's all down to the leverage ratios and the length of the levers.
Without being too scientific about it (I ain't clever enough) ... if the top horizontal lever that you actually move - can have a longer section length aft of its "central" pivot point, AND is longer than the existing bottom lever arm with the ball on currently....then it should have travel/range to spare?
You could start with a longer lever, test it, and then trim it till you get the optimal...or maybe use flat bar for the top pivot... and drill multiple mount holes for the centre and end pivot clevis pins - giving you leverage options to play with and find the optimal?
better explained than i didInteresting stuff. Know sod-all about Lathes but I think I get the external lever/linkage idea.

You could just put a spring on the bottom lever that defaults to disconnect the drive, so you need a simpler extension to operate it without pivots????well no tripping today I should have made the clutch years ago! it has speed up the work a fair bit by not turning the motor on and off every chuck change! Bending down to the lever is tiring though! that needs work now not much room for rods and pivots points in there but I am sure it can be done in a cunning way when I have a spare half a day!
hum possible but it is a cam that moves the motor plate up and down on the leverYou could just put a spring on the bottom lever that defaults to disconnect the drive, so you need a simpler extension to operate it without pivots????
