We're hardly at each others throats treeness.
I'd have just liked to at least hear back from the original poster.

Re: ISC rigging blocks *DELETED*
treeness, it was not a derail and it was a good question, there were probably 35 other people with the same question but would never ask.
I've seen "at everyone's throats" and this isn't like that for sure.
everyone is so sensitive these days
And if we do ever get at each other's throats, big deal, we should forget it and move on.
No one should be afraid to speak up about anything on here, comments and questions are needed for a forum to be useful.

My throat's still intact. I hope Tophopper's is as well.

Re: ISC rigging blocks *DELETED*
If your going to tie them to the end of a rope use a bowline. I tried a triple fisherman once. It seemed like a good idea as it's a better knot than the bowline and the pin pulls out, what could go wrong? Well because it's a cinching knot it tightened up and pushed the plates apart enough that I had to hammer the pin then really wiggle and pry to get the knot to release from the sheave. Close to a knife knot. The block survived the operator error and I'm still using it.

Re: ISC rigging blocks *DELETED*
When I was learning about blocks and their proper use it was always said to orient the block such that the locking mechanism couldn't be pressed open. I've used ISC, CMI and now DMM and always heed that lesson. It's a possibility that it could be opened though one that's less likely.

Re: ISC rigging blocks *DELETED*
A few years ago I was in Wales and went to the new factory to see Denny and Wayne. On the day that I was there Denny's son had the hot job in the casting forge. Ingots of aluminum were stacked in neat piles like cordwood. They would be dropped into the pot and heated. When they were melted the molten aluminum was poured into the molds. After cooling the molds were broken apart and the blanks were stacked against a post like cordwood. The pile of blanks went up about 4' and tapered out about 5'. They were making the middle sized spring block.
I took a lot of pictures but the setting was wrong on my camera. Since the lighting was off all of the pics were a mess. None were decipherable
Denny showed me all of the steps for making the lanyard D0rings for the Kolibri harness. It was interesting to see how a flat blank of aluminum became the final hardware. Several steps in the process.
Over the years there have been a few threads about the spring blocks opening. When a careful investigation is made the same conclusion has been made...the knurled end was placed next to the tree. Add in some combination of movements and the pin opened.
