Weekender SNUPI Builder Posted June 1, 2004 Posted June 1, 2004 Hi Ray, All three local Home Hardware stores were SOLD OUT of the "Outdoor propane Cookers", however have ordered more and I should have mine here by the first of the week ! I guess a lot of folks figured that $ 39.97 was a good price. They apparently make a "fab" stove for doing lobsters. Our company usually has a couple of "Lobster boils" each year and other years have rented the same rig ! The "Powers" ordered a couple from "Home" for the lobster fests ! When you have 200 lbs of lobster to quickly cook for a crew of starvin' Realtors, you want a HOT 'n FAST stove ! I didn't realize the stove you used was the same outfit ! NOW ............. what in blazes did you use to "cook" the lead in ? I'm thinking that this little operation ought to be interesting, having to have to melt, skim and pour a minimum of 150 pounds per bulb half, ( +/-), and having something with stout handles that 2 guys can handle ! Hmmmm ! I "cruised around both sites looking for the pics and story/ direction that you had posted, but no luck. Quote
Weekender SNUPI Builder Posted June 1, 2004 Author Posted June 1, 2004 QUESTION >>>>>> You're saying that you melted 1/2 of the 200+ pounds of lead at one "melting" and poured 1 of the 2 molds of 100 lbs, (+/-), weight in ONE POUR ??????? It seems to me that must have been one hell of a strong aluminum pot ! Or ......... can you do these castings in 2 or more "pours" ? Quote
capt jake Posted June 2, 2004 Posted June 2, 2004 I likely had 150 lbs in each pour. Thus the manly posture in his Avatar!! LOL Ray??? 150# each???> Now really!! Or ......... can you do these castings in 2 or more "pours" ? Only if you keep the top of the first pour molten. A propane torch works well to keep it such; until the next batch is ready. Ideally, it would be in one MANLY pour. ;) "I am a lumberjack and I'm OK, I work all ..."" :) Quote
capt jake Posted June 2, 2004 Posted June 2, 2004 Yes safety is a must! Especially if you are horsing around that much molten material. :shock: Well I had 150 lbs of lead in the crucible when pouring as I wanted to ensure that I had enough lead to fill the mold. OK another line, "Macho, macho man, I got to bea macho man..."... LOL ;) Quote
Weekender SNUPI Builder Posted June 2, 2004 Author Posted June 2, 2004 THANKS, Ray and Jake for the helpful words of wisdom and experience. I'm afraid the heaviest thing I've historically poured was the odd container of " Crown Royal" ! ( For medicinal reasons of course !) You can bet I won't be phone shy when the time comes to do a "pour of something weighing 150 lbs + and at a minimum temp of 700 degrees F ! I'll need to pick your brain relative to the molds and the sand setup you used. POINT OF INTEREST QUERY ....... I'm getting mixed signals relative to the installation of marine grade angle stainless as an "insurance policy" strengthening the "keel ~ sole" connection. I plan on completely encapsulating this piece in several layers of epoxy / f-glass fairing. Some say that O/2 starvation will STILL be an issue , as it would if the angle steel were simply bolted up to the sole and keel . Other " experts say there's no problem , as long as this piece of stainless is completely and totally sealed from the salt water. ( Moored 3 to 4 months yearly ) The other "Voices" say ......... USE BRONZE , it's going to corrode anyway, and the bronze will take longer to "Be Wasted" ! Hmmmmmmmmm , comments ? Quote

I plan on completely encapsulating this piece in several layers of epoxy / f-glass fairing Maybe you are doing something other than what I envision; are you talking about something to strangthen the keel to the hull bottom?? If so; don't worry about it! Just epoxy with cabosil and fair it out. This connection is plenty strong. This thing is attached from stem to stern! No worries . Now if I am mis-interpreting this......... :? Quote
capt jake Posted June 2, 2004 Posted June 2, 2004 Thank you Ray! I do think that 10oz is overkill; but to each their own, it is screwed and glued to the hull and unless you really hang something hefty of of there, well, no worries. . On another thought; six quarts?? I can't find my table of elements at present, but what does a quart (Or a liquid once) of lead weigh?? Six quarts of lead sounds like way more than 150# to me, curious. :? Quote
capt jake Posted June 2, 2004 Posted June 2, 2004 Twice the posts? I consider that being active. OK, Follow the professor as he does the math. A cubic foot of lead weighs about 700 lbs. a Cubic foot of water weighds 62 lbs. A Gallon of water weighs 8 lbs. Hence a Cubic Foot of water contains 31 quarts. 700 lbs divided by 31 quarts = 22.58 lbs to the quart. So 6 quarts of lead weighs actually 135.48 lbs. So I had a bit over the 6 qt line in my cruciuble to ensure I had enought to fill my molds. Want to know how many cubic inches that is? This was the extremely long way of getting to the answer, and thus I will trust you and not double check you math professor. No need to include the weight of water, as we are talking lead. Answer to your question; 346.5 cubic inches. Quote
capt jake Posted June 2, 2004 Posted June 2, 2004 A gallon of water actually weighs 8.34 or 8.35 pounds, depending upon which data you reference. Gosh, did that skew the data? Give me a solid number; who gives a rip abaout the weight of water!!! We are talking lead, right!? The square root of Ray divided by my persistant urge to push buttons times the probablility that Ray will push back .........equals................... nul figure ! ;) :shock: :shock: :shock: Quote
Frank Hagan Posted June 2, 2004 Posted June 2, 2004 We always round it to 7.5 gallons of water per cubic foot (estimating the volume of swimming pools and other bodies of water). Lead weighs more than water. That's why its used as ballast. Now if I can figure out how those guys use WATER for ballast in water ... Quote
Craig Posted June 2, 2004 Posted June 2, 2004 It used to be everyone wanted to be an English major. Now you all want to be engineers!! I used one of the wifes old pans and when the handles burned off I went to vice grips. My pours were about 80 lb each; however, I was casting plates for internal ballast not bulbs. Quote
Weekender SNUPI Builder Posted June 3, 2004 Author Posted June 3, 2004 Re: WATER / LEAD >>>> Jake may be calculating in Imperial Gallons and Ray is working with U.S. gallons ! This will throw the weight of the lead off by 20 % not to mention that if I install a 6" or 15 cm. steel "I-" beam to support my lead keel, I'll have to recalculate after determining whether that beam is 6 or 10 mm. thick ! Maybe I'll install a snorkle and scope and go under the waves & swells ! Quote
Craig Posted June 3, 2004 Posted June 3, 2004 This is way too much for me. I am going back to fixing my rotten hatch coverss... Let's see,,, Imperial lead and 3/32 mm I-beams from water should give me the strength I need. That is until the ice melts and the lead falls through the bottom of the boat! What did you fillet the keel with Grammie? Is it a standard Weekender keel or did you beef it up for the SNUPI modification? Quote
