    long, long, box end wrench:

    ever have a nut or bolt that you need to hold that's way, way down there and you just can't reach?

    I welded a 3' piece of 1/8" steel rod to head of the adjustment screw on a regular pipe hose clamp. So now my adjustment screw is 3' long.

    You put the nut or bolt head in the hose clamp, rotate the rod to tighten it to hold the nut or bolt, and then you can reach anywhere.

    Once you have the bolt where you want it, rotate the rod to release the bolt head.

    like this:

    "0" above is supposed to be the hose clamp

    Most firing rate controls on burners as well as just some honeywell actuators use 135 ohm controls to modulate them. If you are setting up linkages you can use the potentiometer to stroke them. You can also just jump out the terminals. Jump R,B and W together the actuator will go mid stroke. R to W it will go all the way one way and R to B will go all the way the other.




    Also have a simple transformer mounted in a box with a cord for temp power to stuff I'm trying to check out before a site has permanent power.

    That's good to know, I knew about R to B and R to W, but I never thought about jumping the three together. Maybe it will save a little time when I'm checking the dampers after resetting a freeze-stat.

    If I'm trying to find if the freeze-stat is at fault or something else is going on, I take a brand new freeze-stat, open the box exposing the rolled capillary, and set it near the other freeze-stat.

    Fav home made tool

    Ever try to adjust the manifold pressure on Moble home furnace gas valve?
    Well they have the little spring pin protruding up the middle of the sloted adjustment screw.

    The only way I can turn them is to use 2 very tiny pins or srewdriver at the same time in the small area to try and "twist" turn the adjustment screw.
    If you have experenced this you know its a real pain.

    So I made this little tool I will call my Gas valve adjustment key.

    I service a lot of MH furnaces so its used alot. Works like a champ.

    Just two I still have.

    The bracket that holds the standard universal condenser or blower motor to cut the shaft without the motor flopping all over the place;




    And the "Statmaster" thermostat controller;






    Oh- and the coil holder uppers;

    What did you make?

    I just made this Gantry to help lift a few units I got a job for to replace a bunch of slabs and a few compressors at some apts. Thought it would be easier than the genie on the ground they have.
    I plan on the elect winch and/or the pull hoist.

    Made the trolley with steel wheels.

    You can set it up (From 3 pieces) in 3 minutes or less.

    Named it after me.

    So I know your answer is 4 years old, but have recently become verrrry interested in the Lennox Pulse technology and of course always have been interested in the Amana HTM heat exchanger. Care to share any info on what you did to marry these two advanced technologies?

    I am still experimenting and must admit my latest prototype burner was just a tad less successful than hoped, but the custom heat exchanger works like (as my friend from Florida puts it) "a hot dam (sp)!"...

    Or was that post just a joke... I'm still researching, you can respond here or PM me if you wish...

    Sort of looks like something a friend built, he called it "The Drop of Doom"...

    Good job!...

    I built the boxes on the back of my doors for extra storage plus they will hang on an aerial lift. I here a lot of ppl call them wonder boxes.

    The fittings a brazed together, there for my micron gauge.

    The drill sockets for threaded rod.

    I made a valve core tool with a gripper function because I was tired of having valve cores fall of the tip of the tool inside the isolation valve.

    I also made a key chain version which is commercially available but I can't tell you where you can go buy this valve core tool because the moderators would call it shameless advertising!

    I am a service tech first and foremost and I am proud of what I created.

    Homemade subcooler for speeding up recoverys. I connect it between discharge of recovery unit and recovery bottle, in a bucket of ice or water.

    Test lead that i use to tong RAC's, ice machines etc. Active wire is seperated to tong. The plug tops are 10A male and 20A female to allow quick test runs of 20A appliances on 10A sockets.

    What are those fittings you brazed together?
