DIY equiptment and tools

#61
I would be interested in the possibility of buying a light weight unit that would work with 1/2 inch and 9/16 inch lines. (Sorry I don't know the metric equivalent right now.)
13mm and 14mm. The one I showed in the photo is actually just one I'm building for myself. The unit that I think the market needs would have a smaller winch, suitable for the rope diameters you mentioned and with a single speed, power ratio about 18:1. I would like it to be no more than half the retail price of the other larger units if possible.

Looks great man! Can't wait to see some videos of it in action... any idea when it might be finished?

the one I'm making for myself is almost finished. However, it isn't actually the unit I'd like to deliver to the public. I'm using a second hand harken 44 which is very similar to the winch used on the grcs. the device i actually want to make will have the same basic design but feature a smaller winch such as the andersen 18st.
then I'll want to test it, maybe lend it out to a few different companies for feedback and also get an engineer to look at it... and then break test one

When I first started climbing trees, we made all our wire core lanyards with cable and 3 strand rope. I still use a 23 ft homemade cabled lanyard 15/16 in. 3 strand Braided splices on each end, for those monster Trees.(haven't used it in several years) You can really whip that beast. I feel as safe with it as any store bought one.
Before rope slings we would carry several sizes of homemade cable eye slings for attaching blocks to trees. When you did neg. Rigging you had to be sure to leave strategic stubs down the trunk.
Point is it all worked. First fig. 8 I ever used was home made. Grapples too. It was common to make what you needed.

Used to go repelling all the time as a teen, with friends or the boy scouts, "harness" meant tie a big loop in some 1" webbing and pull it around your waist and crotch with a biner. A second carabiner with a lock bar was the entire system for 100' + cliffs, no PPE. I cringe now looking back, we should probably all be dead.

I remember a Swiss ''seat'' in grade school. We had what was called project adventure in phys ed. It was about 12' of 3-strand rope. We wrapped it around our waist, and wove it around our legs, and finished it off by wrapping the rest back around the waist. Tied that off with a square knot, and clipped the biner around the waist wraps. Kinda comfortable for sitting in a rope saddle.

not so much made as assembled, but I always use a loop of webbing, a rated pear link, a micropulley, and a pear biner for false crotch/friction saver. Unlike the fixed-ring straps they sell, I don't have to feed one end of my line through the big ring before pulling it up--I just clip in with the carabiner.

I hope this is allowed in this thread, anyways I was looking to see what tools people have made on your own. I'm not against spending money certain tools, but I do enjoy building and fabricating stuff. So lets see what you guys have made! For example, I built my own bigshot just the other day and it works great, I also came across the DMM throw hook and was thinking about trying to make a similar one.
Thanks,
Newbie

Would love to see and have instructions on your bigshot build. I'm on a budget lol

Here is the Big Shot (REALLY BIG) ha I had a piece of steel that was already bent in a 90deg. so I decided to use it. I would like to hack off some unneeded material from the "arms" and the base because it's so damn big and heavy. But I flip the extending lopper pole upside down and throw it on the bottom. Along with that I also made a hydraulic claw for our Dingo Bucket. It works fairly well but really want a BMG eventually!

Was too cheap to shell out for a big shot, so I fabbed up my own out of schedule I PVC (they did not have any schedule II at Home Depot. I know PVC is dangerous particularly schedule I, so one of the things I have done is to make the air chamber twice the original volume and also to make a barrel extension, this way I can easily hit 80ft shots on 60psi which is much less likely to cause problems than 120psi it required originally. The barrel extension slides on an off so storage is easier, and I have a portable compressor so the larger air chamber is not an issue to fill.
PS I still always wear a face shield just to be as safe as possible.

Also use the plastic box which was free for my throwline, not really a fabrication..just cheap and works great.

Dug up enough stuff laying around to make another speedline setup for light rigging, using a Rig 'N Wrench to control the load. Not going to use that 12-strand for the control line, that's shown in the pic. It was just handy. Going to use some Fly rope and a Petzl I'd below the RnW to hold the tail and allow easy one-handed lowering.
