Hello

My wife wants me to make a number of concrete blocks using a square plastic bucket she has; the dimensions are (in inches) about 10 wide x 10 across X 18 deep.

Does anyone know of a good oil-like substance to coat the inside of the mold? I'm thinking of using a can of thick automotive axle grease I have here, but that might be a bit messy. Any ideas?

My other question is how long I should let the concrete dry before popping the block out of the mold; I want it to set up for a short time, pop it out, and then make another one in the same mode.

Any ideas or suggestions for prepping the mold for easier block removal would also be appreciated.

Thanks in advance for any advice.

Hello. Why would a GFCI circuit breaker trip when the neutral is in its proper place? I put in a hot tub and wired it in via a sub-panel spa panel. It's a Brett Aqualine hot tub with one of those weird 110/240 switches built in via a control panel with A LOT of relays and capacitors involved. The main panel is a big GE 200 amp job; the spa panel is a Murray 125 amp with a 50 amp GFCI included. The GE panel has a standard 40 amp breaker feeding the spa panel and its GFCI. With a regular breaker is placed in the Murray panel the hot tub runs like a skunked monkey. If the 50 amp GFCI breaker is put in WITHOUT putting the neutral in place, it runs the same way, BUT when the neutral is tied in it trips instantly. I tried every thing I could think of without luck. I'm beginning to think the hot tub control panel is bad; maybe I should replace it with a regular 220 volt hot tub control panel; the kind without 3-4 relays and 100s of capacitors tied in on goofy switch. Any ideas? Patrick
