Nice Job Dave, very impressive. I love figuring out how to do stuff myself and you have done a terrific job of that.

thanx Scott ,
but i did cheat a little on the design concept it wasn't mine. ever since the internet came along i look around at other peoples ideas that are posted then design something. alot of the gantry crane design was by a fellow that used 4x4's as the base. i didn't agree with that part at plated wood is stronger. otherwise i swiped his main idea of a i-beam with 4" square tube. i'm also lucky to work with heavy and stupid alot and theatre and road sets have to be simple light and portable so i have a few years of seeing lots of great ideas put into practice. now if i could only scrape together the time to rebuild the roof, fix or replace the floor and wire the whole mess. THEN maybe i can start making some metal chips! d

wow....I just followed this all the way thru.....you got some nice toys there.....ole buddy ole pal ole friend,,,LOL...one thing I was really impressed with,,,you did not burn a hole in the beam for the chain( and destroy 80% of its capabilities...)
interesting world up in Conn,,, gw

Next time please take a video. Going from picture to picture was like watching "Game of Thrones". I was waiting for the final picture with a collapsed crane from all the weight as it was lowered, the weight seems to increases with distance. Looking at how many boats slip off cranes when lowered into a lake got me nervous looking at each picture. Great job Dave, next time give me a call and I will drive my lift truck up to make it a simpler job. The lift trucks needs some hours on it and the drive will do it good and I always like a parade. Wonder how many tickets I could get on the drive and they wouldn't be for speeding.

thanx for kind words.
a video would've been hard as i was working alone a big sin but unavoidable. plus if it went south i didn't want evidence of why!! i do rig for a living hanging from 40 to 140 feet in the air or standing on a beam setting chain motor points so i do know a little about picking a load up. here's a pix of a riggers point of view in case you're wondering what the heck i am talking about uk riggers but same as where i hang out during work hours.jpg (Size: 221.55 KB / Downloads: 16) pretty good idea of the points we hang here..png (Size: 1.13 MB / Downloads: 15) the gantry set up seemed a little dicey and i wasn't totally sure it was safe as i didn't bother looking up load bearing ability of everything. i was copying a design that someone else used successfully and improved a few building points i figured i was ok. of course i was still nervous. Jim, i'd like to see this lift truck but i'd need the gantry anyway. i still have to move the other machine tools . plus , at some point this year i am replacing the bed on my pickup truck with the new to me one. i'm hoping that the cement floor in the garage is salvageable with some grinding . otherwise i'll need to go to phase two and build the addition before i get the mill into operation. i considered replacing the rough floor if the floor can't be ground flat and level enough for the mill. but it's probably easier just to start with a spec built floor in a new section. trying to break up old floor and re-pour it would require removing everything first for at least a couple of weeks. a horrible idea imho. anyway nothing can be done for next couple of weeks , am in middle of stupid level of work . been working every day for last seven , i get tuesday wendsday off this week. then almost solid hours till tuesday next week. might get enough time to sleep some but that's gonna be limited. feast or famine as a stagehand! later d
