    Thanks for your time in this in-depth video. For me it makes more sense to just buy this for $190 that fits with the machine but watching you build this was definitely educational. Great work!

    I used to run a backhoe on a farm. It had a linkage driven thumb as you curled the bucket it would pinch the thumb. It wasn't the best for digging but did well enough. Most jobs on the farm were manipulating object and for that it worked great.

  • @smca7271
    @smca7271 6 месяцев назад

    Thats a great build,one thing to watch is the bucket can can put a huge force on thumb (even bend the thumb cylinder) so they usually have a relief on the thumb set lower than the bucket force,so it pushes the thumb instead of bending it...but if your dont overdo it,should be good.

    • @FabbinAdventures
      @FabbinAdventures  6 месяцев назад +1

      Well, ive worked it pretty hard already and it hasnt bent anything, if i push with the bucket hard enough it seems the thumb retracts a little, so im not too worried about it, doesnt seem to have the power to hurt anything...sofar.

      By the time you bend over and pick up and cut 1 or 2 of these trees in this yard we are played out.
      I cut up 3 or 4 trees by myself with the mini x and it was nothin!

  • @backdoormanintheend
    @backdoormanintheend 8 месяцев назад

    Very impressive. How hard can you pinch something? Do commercially built systems have some kind of pressure relief valve so that it doesn't exceed a certain spec? Some thumbs will "give way" to bucket pressure and not be damaged.

    • @FabbinAdventures
      @FabbinAdventures  8 месяцев назад

      It squeezes plenty hard for what it is. Enough to pick up some heavy logs.
      Yes the big machines have a pressure relief from what i understand. Im not sure that these little things need it especially since i'll be the only one running it and am aware of its pressure and limits.

    Thanks for the excellent video!
    I have 2 questions:
    1. When you cut off the two upper 3-hole brackets - why not re-use them? Grind off the two bottom holes and leave enough for the pin and weld back on higher. Why re-make the pin if there is a pin already? Just curious how to do this without a lathe and CNC cutter.
    2. Some other video mentioned the thumb fighting against the bucket when all fully closed - any thoughts on this.
    Thank you kindly!!!

    • @FabbinAdventures
      @FabbinAdventures  9 месяцев назад +1

      The 3 hole bracket doesnt hold the ram far enough away from the arm to make room for the hydraulic fittings and gives the ram a little better angle to push on the thumb.
      The pin wasnt long enough to go all the way through so i had to make a longer one, a bolt coulda been used but i like their pin idea.
      I havent seen a problem with the thumb fighting the bucket, also not quite sure what you mean by that.
      You could get it all done with a big drill press, side grinder with cut off wheels and a welder.

      I contacted yes welder to see if they would send me their cut 65ds to review, they agreed, but sent the wrong one. They sent the cut 55 instead unfortunately.
      I want to try it out with the arcdroid, it should work and the consumables are way cheaper and easier to get.
      Hopefully they take this plasma back and send me the right one, i should see it mid next week.

The attachment points look the same as yours. I ordered the same ram (2" x 8") from Princess Auto as my local store in Red Deer didn't have stock. I am impressed with your plasma cutting tool! Where were you able to buy the hydraulic adapters? I really appreciate you listing the part numbers.

      Guess i know what i'll be making next. The drain for my shop froze off in that -45C we had, so im diging it up to thaw and drain it. Tough digging, but im getting there with one tooth on the bucket like a ripper plus im using my big diesel heater and some sheet steel as a tunnel/deflector to thaw the ground. Only -12C today so i am making head ways.
      They sure are a pretty handy little machine, i have a fan to put in it and will be doing an oil change after todays work for sure.

    Hey I'm new to your Channel, good stuff thank you. Everybody complains about the same thing with this machine the blade does not stick out far enough in front to pick up a heavy load. I think you could mock up a blade that sits on the original with maybe a couple pins ,back to the arms. Make it stick out another 1 ft, so you can pick up the loose dirt and a heavier load. If I had a shop and the tools I know I could do it.

      @FabbinAdventures  9 месяцев назад

      Sofar i havent seen a need to extend the blade out. It could be taller and wider for sure. Sticking it out further would give more leverage for when digging. I will see this spring when i actually get to use it for digging whether it needs it or not.
      If it does, i'll be modifying ot for sure.

      Not trying to make you look bad, and your right, if i had to make one for someone else it would run around $600 probably.
      But what im saying here is you don't need a bunch of fancy tools to make this mod, a drill, a cheap welder, a side grinder and it could be done. The fact that it took me more than 30 years of saving and buying a tool here and there so i could make something or fix something is why i have all these tools now. Some are new, but i buy lots of second hand equipment. I'm cheap..lol so i buy used or cheaper decent "non big brand" equipment. Non of my stuff is top of the line. The lathe is a knock off and is my highest dollar piece i have which i bought brand new on sale for $4500 which i made payments on for a few years, the cnc plasma was the same, about $3500.
      I'm not trying to down play anything, some guys have way fancier stuff worth way more money.
      I like to fab stuff, thats what i do for fun, some guys blow their money at casinos, thousands of dollars!, some guy probably knit sweaters..lol but i dont kive them a hard time for that.
      So just because i spent my money on a few cool tools and use them occasionally doesnt make me any better or worse than the guy who can make the same thing with hand tools...i was there once too.
