    That was a tree that grew on the same property that I grew up on. Talks of bulldozing it and burying it under the ground seemed goofy to me.

    No specific plans, lot of what I'd LIKE to do, given the time. Hoping some passionate woodworkers would scoop it up but I damn near gave some away with nothing but tire kickers.

    Very rare to see it of any size around here.

    Small Sunday update.

    Plates are welded up.

    Today went like this: set up welder, clean off scrap to run some test beads, weld plate, daughter is hungry, throw pizza in, weld other plate, dig out drill press, daughter wants to show me her fort, fiddle with drill press, start SLOWLY drilling hole, daughter is hungry.

    I'm still chipping away at it.

    At this point in the build, I've gotten pretty thirsty so I decided to make myself some fancy cup holders.

    Gratuitous action shot. ;)

    Good thing she's rated for a billion pounds.

    I guessed 20-25, my wife guessed 25-30. I looked at my receipt and the steel untouched weighs 37 lbs. So subtract my taper cut on on the side plates, 4 drilled holes and then add some welds I'd say thirty is pretty close. I'll have to officially weigh it.

    Unfortunately you're going to literally burn through your rigging line with all that friction in the block. The steel will hold the heat, you have no bearings or sleeve. If for some ungodly reason the system does fail and something gets damaged or someone hurt, the insurance inspector will probably not cover it as you used home made equipment where there is a regulated industry standard. Just keeping it real.

    There isn't a huge amount of friction within the block, less than I hoped for to be honest. Getting some heftier loads on it should help in that department.

    It would take a LOT of friction to heat this block up. More than I can see ever happening in a tree rigging scenario.

    Are you familiar with rigging rings or a portawrap? A Portawrap doesn't have any moving parts, isn't typically made of aluminum(side note, climbing gear being made from aluminum typically has nothing to do with heat and everything to do with weight) and will have multiple full wraps on it which would introduce a lot more friction than this block will see, which funny enough is the entire concept on how they work.

    I will do thorough testing(playing :cool:) with this before it ever leaves my property.

    Regulated industry standard equipment gets used, and misused everyday. Consequently there are failures that happen regularly to the equipment, rated or not. Misuse and exceeding limits are probably more of a concern than anything else.

    To be honest I do have one element that I am not 100% sold on but you didn't touch on it.

    It doesn't come standard with every 25lb port-wrap?

    I am into building some of my own tools as well. I Haven't built any rigging gear yet but I have some ideas I’ve been working on for quite some time. Being that I co own a fab shop makes things a little easier...

    I like the idea and concept. But few issue I noticed. your weld joints definitely are the weakest point. The inner side cheek plates should really have been beveled and to be filled with additional passes of weld. In Really The pipe sections should have be welded to the inner cheek plates on both side. Finally prep the outside face welds and then capped with the second set of cheek plate. That would give you much more strength in case of side loading.

    Last thing I noticed was there still a lot of edges and corners. I’d be cautious. what might not seem sharp to the hand can easily tear up a rope moving as high speed.

    I had the same thought. That said, I'm not disrespecting the effort. That's some cool homemade gear. :cool:

    No worries at all fellas, I appreciate any interest, critiques, or concerns.

    That has been on my mind as well, the side plates are all beveled already, but I may go more. Being attached by sling the work angle shouldn't be too bad.

    That would be some awful pretty rope to tear into. :mad:
