A Slight Mod
« on: August 31, 2021, 05:10:38 PM »
LOGRITES have roll pins to limit the range of movement of the hooks, and if 'properly' used should never wear/break, but 'properly' is the key word.  Anyway, I occasionally have to replace some roll pins, that is until now.


 
Roll pins removed.


 
" X 1" grade 8 bolts e/w lock nuts.


 
Installed


 
And tightened.


 
An example of some of the removed roll pins.  Bet that it will not happen again.   logrite_cool

On edit:  I forgot to mention that I did both of my 48's and both of the 60's.  Total for 8 bolts & nuts: $2.82.

I love having those roll pins in there, it is the difference between a high quality, well designed tool and... all the others. They have saved my knuckles more times than I can count. But it looks like you used bigger diameter screws that the roll pins so that means you altered the range of motion on the hook a bit more. Will that have an effect on function? Inquiring minds want to know. ;D ;D

OGH, little if any from my practical research. By that I mean that its not going to limit how close the hook will close & the back of the hook always hits the main structure anyway, so why not!?

Nope, the " roll pins were replaced with " bolts.  No difference.

No @Tacotodd, the hook movement in each direction is limited by the roll pins, (now bolts) not the main structure.

Well Todd, it's exactly as MM said, that rear pin keeps the hook from swinging back too far and getting near the handle shaft. The first moment I picked up a LogRite and realized these folks are more than on the ball. It may sound like exaggeration, but I spent many years designing things for others to build and use, spending countless hours considering each detail and how to enhance function, reliability, or buildability (my word). So a detail like this tells we somebody put in the same kind of care. adding those holes adds cost because you either drill all the holes in those plates before welding then deal with alignment issues or put the holes in after welding adding another operation. SO the designer has to weigh the balance between cost and function and decide if the cost is worth the outcome. I am glad he put those holes in. I consider those pins a wear part that need replacing periodically from the beating they take when you jam the hook into and log and other daily use. Again, the design allows for easy replacement and they cost pennies. I'll be curious to see how MM's mod works out over time. The screws will likely transfer more of the shock load to the clevis plates and could oblong the holes. Not likely, but will be interesting to see over time.
 On my old hook I can't tell you how many times I picked it up by the haft around the joint, stood it up and had that hook swing down and smash my fingers. It hurts like the dickens. Can't do that with a logrite. The tool has other subtle yet extremely fundamental advantages over the run of the mill stuff. I'd never buy anything else.
 I have always admired what I call 'elegant' designs. That doesn't mean they are complex and fancy, but just the opposite, they have reduced the desired functions to the simplest possible number of components with the least production cost, that work better than other competing designs and are easily repairable.
