    Default davit build

    Here's some pix of the davit that I am working on for my 22 hewes OP. I am a very novice welder......and I have borrowed the main design from AKMud.

    Setting up the main fulcrum/pivot for weld.

    Upright welded on, gussets installed, and fitting the support arms to the beam

    Hole cut into the roof

    I have made a little bit of progress since these pix, but not much. I'll get more photos later.

    I should note that it would be much cheaper to just have AKMud make yours for you instead of trying to do it yourself. He quoted me a number that makes my labor worth almost zero. The project has been fun and I needed to justify the welder purchase. Aluminum is expensive and so are the misc materials required.

    It may be more cost effective to hire it out, but where is the fun in that?!

    Looking good 👍

    I've got plenty of wire on hand if you can't find any.

    I stopped by to see how the davit was coming along. His pics don't show how much work he's put into this. It's turning out great. Everything fits nice and snug, nice welds and it's going to be very stout.
    Randy, can ya let me know what the part number of your shock was? Having trouble finding the length you got. Guess I should have measured it today.

    Looks good. Welds look great!!You say your a novice welder is that just for aluminum? Or you weld steel before? I've done lots of steel thinking about getting in to aluminum.

    Are you preheating the aluminum? I got a Miller with a spool gun, but I have not come close to doing very well with aluminum, can weld steel fairly well.

    I admire your willingness to DIY, looking good!!

    What are you guys fusing your Electrodynes at? I bought a 50 amp breaker, but am now questioning whether I should have went to 60. The motor is rated at 36-45 amps. I am putting in arctic cable 6 guage. It is a two conductor cable and I have a run of under 12 foot. The breaker will be at the battery.

    I went with a 100 amp breaker on mine. I believe that's what Steve recommended.

    Hi Steve,

    You have to clean the aluminum very good. Use a separate stainless steel brush and use it only for your aluminum. I also wipe after brushing - - with Acetone (ouch!). You have to push instead of pull like steel. You also need to try to make a splatter weld - you have to keep about 3/4" distance from the tip minimum. Also - no wind. You have to keep the shield gas intact. Also - should use 100% argon.

    What size miller do you have? I found my 140 to be too small to do much with.
