    Sistine Chapel

    Thanks Bill, Michelangelo did these works shortly after Columbus discovered America in the 1500's. The objective was to convey stories & messages that were of great value --- in this case mostly from the Old Testament. http://wiki.answers.com/Q/What_did_Michelangelo_paint_in_the_Sistine_chapel

    Boiler being replaced-- what should I watch for?

    Sequoia, Here we need 50-50 glycol or fluid protection to minus 40 so we do not have an inlet to maintain fluid because the risk of potential dilution is greater than the risk of potential low boiler water. Low water condition can be protected with pressure switch or a low water cut off along...

    Raypak Boilers

    Kluge, How many BTU? Our fees are $20 for the certificate & if a change or repair of pressure vessel is happening ---- another additional $40 per boiler. This extra cost can potentially add up if a person has many modular boilers. How many hours of schooling & exam requirements is involved...

    Merry Christmas & a Happy New Year

    Merry Christmas & Happy New Year! Merry Christmas to Bill & the rest of the forum! Bill, thanks for stopping to see us here in North Dakota back in October even though it was out the way of the more likely route. We do value your friendship. There are times when I visualize Bill Pitzer...

    Best Changer???

    Waterway, We like our 2 600EF Standards --- their heavier duty version. We have them inside in the more dry environment of the launderette portion of our facility ----which could be a factor though. Remote access to them via a remote computer is nice & the fact that they shared their code...

    Adding a R.O. Membrane. How do I plumb it?

    Kirb, If it were mine, I would be leaning towards having a ball valve just before the inlet of each of the membranes to use for balancing the system just in case --- more flow occurred to the first teed off membrane on the manifold. MJ

    Pumping Methanol Foaming Brush from a 55 Gallon Drum

    Our Experience Buzzie8, For over 15 years we successfully used a set up that mounted a 0-5 psi gauge with a 0-5 psi regulator with the right drum fitting on the drum & tube for the chemical going to the bottom of the drum. This was to tranfer different chemicals to a 5 gallon pail. As the...

    Some perspective on underdeveloped areas.

    For over 15 years, I have been involved with a charity (God's Child Project) even to the point of being with them at one of their facilities back in 1998 even though the United States State Department was advising no American travel. Since then the advisory has been lifted. For my fellow forum...

    How much volume per linear ft. in 3/8" hose?

    Mep007, I agree --- good observations---- those were my thoughts also. Pat did raise a good question & in the end it does turn out all those heavy measurements that I unfairly suggested of him won't be needed ---- as he has better things to focus in on --- like the "Christmas Spirit" etc. MJ

    How much volume per linear ft. in 3/8" hose?

    Pat, Good point ---- there is probably some swelling going on inside that hose as it is pressurized. Your assignment is to measure how much swelling actually occurs at the precise pressure. Yes Mr I.B. Washincars, you deserve an award too! Bill ---- could you arrange that! Do think if I...

    regulator vs. mini-regulator

    Jimmy, I am not sure I am reading your post right but if you used a caliper then 1/2" OD would actually be closer to 1/4" pipe & probably 1/4" NPT threads. Based on the iron pipe chart at the link below. http://www.gizmology.net/pipe.htm MJ

    How much volume per linear ft. in 3/8" hose?

    Experience tools etc On a previous post I was not clear enough. I failed to mention with that specific post that I was verifying using a 3/8"square & elongating it Twodose's 85.5' ---- would explain the slightly more amount of fluid. This thread reminds me of a few years back when we repaired...

    How much volume per linear ft. in 3/8" hose?

    Erosion or manufacturing tolerance factor! Sleuthing along Twodose, Mac, Mep007, Pat, & others, Several of us came up with close to my 1.3254 per foot post. Mac came up with that figure first --- so he deserves the prize for that. Mep007 deserves the prize for verifying it the most...

    How much volume per linear ft. in 3/8" hose?

    Twodose, I came up with .49004 gallons. I will be very surprised if this figure is off based on past experience. One way of verifying is using (12" x .375" x .375") x 85.5 = 144.28 cubic inches which converts to volume of .62459 with an online conversion. This is more volume but it seems to...

    How much volume per linear ft. in 3/8" hose?

    Twodose, I came up with 1.324 cubic inches per foot with a CAD program. If you multiply that by the number feet you should be fairly accurate cubic inch wise. With that figure you can use any number of online conversions to get quarts, gallons or whatever. I hope this helps. Let us know if...

    Floor Heat Circulating Pump - Spare

    Original Motors??? Bubbles, It looks like from your picture that might be a Huron Valley Raypak setup similar to ours. It appears that you probably have a Sure-Flex Coupler between the motor & the pump. I recently changed the motor on mine that is mounted separately from the pump via the...

    Bay temp alarm

    Any other choices on dialer brands & models? Running low voltage wires to activate a normally open relay & then to a wired dialer seems to make the most sense. A docking station from a cell phone would make it even more fail safe because it would provide the wireless outside of the building...

    Be careful if you have RFID Credit Cards

    Bill, Thanks for sharing the light. If they can't come up with a cost efficient way of shielding those numbers this news could change POS development dynamics. Are there car wash devices that depend on RFID or under development? I know in the self service laundry industry there is an outfit...

    Magic Heat

    Picture & info Bubbles - John & others, http://s26.photobucket.com/albums/c138/mjwalsh/ The pic shows the black wrap around the like new 399K Huron Valley Raypak. I don't know if they still sell that at hardware stores anymore but it does safely disperse more heat that just the vent surface...
