    Should I step up my voltage from 208/230 volt three phase to 480 volt three phase for a larger compressor and motor?

    No savings to be had by stepping up the voltage. If the full load amperage on 240/3 is 59A, then the input side of the transformer is still going to be pulling 59A plus whatever internal losses are inherent in the transformer. As dozer fixer mentioned, you could have starting problems with a...

    Is there a Harbor Freight tool truck yet ?

    No reason I can dream up that would cause the owner of HF to want to enter the tool truck business. HF's gross revenue is 1.5X that of Snap On and all of its subsidiaries. Eric Smidt's net worth is over $9 billion. Snap On's total market cap is a bit over $12 billion, so if Smidt wanted to...

    If you buy a Juki, be sure to get the 1541S model rather than the standard 1541. The S model has a safety clutch in the underneath drive mechanism while the standard one does not. The safety clutch allows the machine to "pop out of gear" in the case of a bad thread jam or other condition that...

    How to bend 16ga sheet metal?

    Same here, both HR and CR. In my 10ft 16ga leaf brake I can bend either one with a dead sharp (zero inside radius) bend without cracking. I've also had several instances where I hemmed 16ga (folded the material flat on itself) using a press brake and hemming dies, also without cracking. I...

    1964 Skylark Restoration-Pitted Metal

    Ospho, metal prep, etc are phosphoric acid products and not zinc phosphate. FWIW, there is no such substance as rust oxite, nor is there any such thing as iron oxite. POR15 is not air cure epoxy. It is moisture cure urethane.

    Mr Cool Remote Thermostat set temperature not in sync with temperature in building

    In follow mode, the remote should control the unit regardless of the elevation of the remote. If stratification caused the temp at the ceiling to be 90* and the temp at the remote was 60* with a 70* setpoint, the unit should continue to crank out heat and attempt to satisfy the setpoint at the...

    Mr Cool Remote Thermostat set temperature not in sync with temperature in building

    Need clarification. Is the unit holding the set point and the remote is displaying a lower but inaccurate temp? Or, does the room temp agree with the temp displayed on the remote even though that temp is several degrees below the setpoint? Both systems having the same apparent problem would...

    HVAC for Retirement Shop Upgrade

    IMO, this is your best option for economical operation. If you look at the max capacities of a single 36K unit vs two 18K units, you'll find that the pair of 18K units will have a max capacity in both heating and cooling that's greater than the single 36K. The SEER rating is also higher on the...

    Cutting oil connoisseurs

    When turning steel, the primary concern is avoiding chips welding to the cutting edge. A small amount of dark cutting oil will prevent chip welding. When milling steel with the side of an end mill, the primary concern is avoiding recutting chips that are carried around by the tool and back...

    Cute little steel angle

    16ga galvanized sheet will be dead soft annealed and capable of being bent flat on itself (hemmed) without cracking regardless of whether the strip is cut across the sheet or along its length. This is a requirement for the ability to run a Pittsburgh lock on any edge. Any duct shop with either...

    New cable hoist pendant help

    If you Google Dutton lainson winch parts, all parts are available from the company. FWIW, that's a winch and not a hoist which means it's made for dragging stuff rather than lifting.

    Piping question

    Forget the lubricator. It will contaminate any air hose you connect to it as well as covering your car with oil contaminated air when you use your air tools. A single drop of oil in the air inlet of an air tool for every 8 hours of use will provide adequate lubrication. Most guys who work in...

    Electroplating a vise?

    On a vise I'd go with electroless nickel. It plates evenly while chrome tends to build up on corners and not plate into holes. EN is also cheap as compared to chrome.

    Air compressor pump discharge materials? Class 300 iron, L copper or other?

    I'd use a hydraulic hose. It will serve to isolate any vibrations that can be problematic with hard piping everything. You could use Type L soft copper, but bending large tubing is difficult even with a bender, and a tube bender for 3/4 copper is an expensive tool for one use. Although some...
