    Default Trapdoor Gin Pole Project underway, feedback/suggestions appreciated.

    First the mandantory disclaimer I am not an ME, nor have I done any calculations on what I am building. This is only a ongoing documentation of what I am building to suit my own needs. No warranty is stated or implied as to fitness and safety of what I am building. Use the info at your own risk! Etc, etc you get the gist.....
    It has finally started,
    After extinguishing all options on the remove and replace motor in the M135, I researched for what has to be over a year and came up with the preliminary design to follow (BTW the best sources of info is here and welding web if you want to build your own). The boom poles are sized the same as a truck on welding we with the outer legs 2 1/2" by 3/16"
    wall by 10' square tube, the inner tube is 2" by 1/4" wall by 10'. I will be using a separate sleeved lower leg that is patterned after the pole-setting trucks. I have a Hummper 12,000 lbs electric winch that is a planetary type that I might have to change out for a worm drive down the line (it has been said that the worm drives hold the load better and last longer with a gin pole setup) but its a run whatcha go situation. Pleas feel free to make comments and suggestions here are my crude drawings and parts I have on hand as of right now:

    You will note that I have 3 different mast head designs, my favorite is the first one, but would be permanent unless I wanted to remove the hook to take it down. The third one is the simplest, but as of right now I am leaning towards the second one.
    I am waiting on the rest of my steel material order and the following parts from ePay

    ​Tell me what you think...Thanks!

    "my steel material order" Just drilling 5/8" holes thru 1/4" and 5/16" steel.
    What flavor steels are ordered?
    Is it 1018 or what is it your going to use?
    Is it steel referred to as A572 grade 55?
    I was here, had a good time.

    HiYa Frank,
    Some flavors are easy others are not so much
    The tube is A-500
    bought plate is 1018 or 1020 hot rolled
    The 5/16ish plate on the other hand is a little harder to pin down. It is leftover Japanese steel from a Mitsubishi elevator retrofit mod we did at my day job almost 2 years ago. It and the 4130 steel I have are the only steels in my garage that don't have flash rust on them so it is made of some better stuff. This plate is definitely not 4130 but much better composition than the 1018/1020 steel...but cost me nothing.

    Are you drilling freehand with portable or a drill press or a portable magnetic drill press?
    Are you using Morse taper twist drills or a chuck with Silver and Deming type twist drills?
    If you could reduce the font size you are using, that would be helpful, I can read your posts from across the room.
    I was here, had a good time.

    It gives me a headache when I type small font and already have my screen set for 150% and use glasses when on the computer and measuring, I guess this is my handicap.
    I will always avoid freehand drilling whenever possible. My machines are a 1969 Black and Decker mag drill with a cracked motor case with a 1/2 inch Jacobs chuck for the silver and deming twist drill bits. The drill press I use is a mutt made up of a late 1950's Craftsman base and pedastal/table with a 1975 Rockwell head and a 3/8" Jacobs chuck for the silver and deming twist drill bits.

    Is font size 3 better? I can still read this without glasses.

    A little more of where tentatively the boom storage would be:
    I think the wood runner between the bed and frame on the M135 was 1 1/2 to 2". I had some pieces of it but the wife thought it was termite infested and tossed it out for me. The design right now has the option of the poles in a trough (sp it doesn't quite look right) beside the wheel well inside the bed or under the bed along frame rails (only viable for those who single out the rear of their trucks like I have) or above the frame rails and beside to the outside of a 3 inch wood runner between bed and frame. The last one is the best for a nice bed. A M211 would have it easier I think.
