@@TheChainsawLama I use to use them when I use to install t.v. towers many many moons ago it was handy to use but also when ur the only person up 60 ft in the air it was interesting to say the least moving it from section to section lol, I worst part of using it was who ever was on the ground pulling on the rope or cable and the section of tower getting hung up lol talk about failure to communicate 🤣🤣 but satellite dishes, cell phones sorta killed that business, not many people have anything to do with towers and the tools used, to bad can not add photos to messages cause I could pics of the ginpole I use to use, best thing of that job was the scenery !
Gin pole, eh? I built one of those last year to pull stumps. . . . Not being familiar with that terminology I chose to call it my "Egyptian-style stump-puller". As you can probably tell I am pretty proud of it! 😆
So that is what a GIN pole is, I've always wondered since childhood hearing my Grandfather talk about them with other adults on the farm. I have used them many times in my career and have always called them "Aframelifts". My Grandfather was German and I am 78YO. Thanks for clearing that up!
Yeah I always used to call it a lifting frame but apparently a single pole, an A-frame, and a tripod rigged in this way is a Gin pole. Many videos on line. And it works great BTW
Is a "shearleg", not a "ginpole", surely (?!). Familiar derricks are ginpoles, shearlegs, tripods and stiffleg-derricks/scotch+derricks - all four exist and are very different - have very different applications too.
Ahh! thank you that is very helpful. I was searching for the American name for this and found a video that explained it was one type of ginpole. I always called it a lifting frame or an A-frame crane. ua-cam.com/video/1cvK5E3Qt-g/v-deo.htmlsi=RdL5SmwszHORiIKi ua-cam.com/video/41aB0lFe_1w/v-deo.htmlsi=fZjuhPXWnTtkDAmH
That is an a frame or shear leg crane. Gin pole is one spare held up by three or more lines and can rotate somewhat around by changing tension in guy line to move load laterally.Does not change the great job you did.
Thanks for clarifying. Previously never used this term but when looking on UA-cam for ideas for the title, one guy described this as a type of Gin pole. Previously I always called this an A-frame or lifting frame.
Doesn't the cross member of the "A" experience tension verses compression? The notch joints are good for compression. The carriage bolts are absorbing the tension.
@@arnoldwillis7685 Yes Arnold part of the reason why I made the crosspiece higher up because of the tendency for the upright sides of the triangle to bow out. In practice the majority of the force is directed to the feet of the frame and there seems to be very little tendency the sides to part. Rather the whole frame seems to compress along the face (perform a backbend) so I will probably move the eye bolt to the other side and flip the frame over (so the joins compress and tighten) Some kind of hooked joint would be stronger just as you say, but I my guess that as is the upright legs would fail long before the bolted joints (that appear to be under very little stress) would. Also these joints were incredibly quick and simple to make. Thanks for your suggestions it give me a lot to think about for future builds.
This is not a gin pole; it is sheer legs (or just “sheers” for short). A gin pole is a single pole with guys. Gin poles are quick and easy, but can be difficult to find places to guy them to keep them from moving laterally. The sheers are more stable to lift things, but too heavy to easily move around or take to the top of a tower or building, or too complicated to transport or assemble in the field. It requires three people to safely manipulate a gin pole, but if you are an experienced rigger, the sheers can be a solo job. The half laps on wooden sheers are usually only made in the cross brace so that the legs are not weakened by thinning them to half thickness. In the field, it also helps to supplement the cross brace with a ratchet strap or rope to hold the frame together, since the cross brace is in tension under load. A useful trick I learned about using sheers is to make an attachment for a vertical pole to a second cross brace under the legs near the apex. This forms what sailors call a “gyn”, and can lift even heavier loads, such as lifting something massive so you can back the truck bed or wagon under it. In this use, the feet of the sheers must be secured not only laterally, but also vertically since they might lift out of the holes.
Yes thank you for that, several other people have already pointed this out. I was at a loss for the American name for this lifting frame and quite a few videos on UA-cam called it a Gin pole, so I just went with that. I see now that was a mistake.
Found it amusing that you came on with a safety lecture about the ladder, but not a word on the chainsaw. Also - tying the ladder to the tree? After you climb it without, then untie and climb back down ;) I get the idea, but the irony is blatant. Cutting the notches with the chainsaw - why not use a plunge cut to get the flat bottom? You had plenty of room and it would be much more efficient than the multiple vertical cuts and having to knock out all the waste and still need more cutting ;) With a chop saw it makes sense, but the chainsaw lets you avoid all of that.
❤ not confident enough with my plunge cuts yet (beginner) and the 16 footers are too awkward to get on the DeWalt. But the joint was tight in the end so I am pretty happy with the outcome. ❤

I used to work in an orange jumpsuit. Then I got out
😆🤣😆 I had to look for something with monk colours! 😆🤣😆
Mine had stripes (orange)
@@donaldwasden8657 Was that an actual prison suit?
Thanks! I enjoyed the video.
Thanks friend 👍
At centre of ladder I use a rachet strap as extra tie in.
Thanks for that!
That's one helluva chisel! I see one of those in my very near future.
Its a 2" framng chisel available online. Essential for japanese (and Korean) style woden framed buildings!
Now you have 312 subscribers. Nice half lap joints for your frame. Always enjoyable doing things single handily.
Thanks for you subscription Steve, we will get there slowly!
I'm your 367th sub! Satisfying build.
Thank you Stephan your support in growing the channel is appreciated!
Good choice of music.
Kinda cheery
Clearly you have earned your title as the "Chainsaw Lama" ... you got some handy skills in general though, much more than me anyways
Still learning Gunk!
Around here, you're more likely to hear someone say "hold my beer" than you will "hold my ladder"😂
😆🤣😆That's so friggin funny, but I don't have anybody to hold my beer or hold my ladder!!😆🤣😆
There's also a tower gin pole also which is used to manually install one section of t.v. towers ( freestanding and braced )
Thanks JOhn I will look into it😃

And you deserve to be proud JAmes. I think Gin pole is an American name. I always called them a lifting Aframe.

A-frame = shearleg ?
@@RichardSmith-ms6hh Yeah I now know it is a Shearleg thanks
That’s a mad chainsaw skills right there
Thanks Bill. TBH I am a bit of a newbie!
looked a bit dodgy, but you got there in the end!
😆🤣😆 Works a treat mate! Over engineered for the job. I will post a full video of the sawmill unpacking and assembly with lifting gear 😆🤣😆
