01:14 katsmeow-afk hmm?
01:15 rue_house airmuscle?
01:15 rue_house hmm thunder...
01:22 katsmeow-afk oh
01:24 rue_bed lots of thunder and lightning
01:25 rue_bed I need to get the genorator going again
01:25 katsmeow-afk batteries charged? gennies fueled?
01:25 rue_bed I have to make another muffler clamp
01:26 rue_bed I am making a compressed flange to pipe fitting, I started by welding studs to the outside edges of a coupler
01:26 rue_bed I have to make a compression plate
01:26 tsmeow-afk would suggest mounting the muffler to the frame, and use flex hose from the engine to it,, that way you can weld/braze all the frame-mounted p
01:26 rue_bed I'll get you a pic later
01:26 rue_bed yup
01:26 rue_bed I used allthread to make straps around the muffler to the frame
01:27 rue_bed painted it all first (not hte muffler)
01:27 katsmeow-afk like http://designerthinking.com/images/generator-little/IMG_0920m.jpg ?
01:27 rue_bed the 'flex hose' I have is corrigated stainless pipe
01:27 katsmeow-afk like http://designerthinking.com/images/generator-little/IMG_0921m.jpg ?
01:28 katsmeow-afk i made the flange-to-3/4-pipe adaptor there
01:28 rue_bed dosn't you muffler get hot enough to release a brazed joint?
01:28 katsmeow-afk no, cause the zinc fluffs up
01:28 rue_bed oh
01:29 katsmeow-afk however, the weight was enough that the bolted pulled the threads out of the engine head
01:29 rue_bed I went direct to the corrigated, I think it'll work, I need to get my tig tuff going
01:29 rue_bed yea, I didn't want any weight on the muffler mounts
01:30 katsmeow-afk http://designerthinking.com/images/generator-little/IMG_1275m.jpg is the long version with the thru-bolts and nuts on the backside of the aluminum
01:30 rue_bed instead of bolts direct into the engine, I used peices of allthread, that way, when they sieze in, I can still take the nut off and change things
01:30 katsmeow-afk i think i'll go with the lightest possible flange-to-flex
01:31 rue_bed the corrigated stainless I got was about $5 (1 foot)
01:31 rue_bed iirc, 12 or so chipping
01:31 katsmeow-afk won't work any better, sorta-althread is used on some car engines, the nuts still sieze up
01:31 rue_bed yup, but I can cut the nut off and still have a usable stud
01:32 katsmeow-afk k
01:32 rue_bed or better odds there in
01:32 tsmeow-afk
01:32 rue_bed wow, continious thunder
01:32 rue_bed and its pouring rain
01:32 rue_bed I forgot that it rains so much I cant ever do any welding
01:33 katsmeow-afk i discovered i wasn't getting 80 cents for aluminum, the "80" was PERcent factor he used in some math,, i got 40 cents, was hardly worth returning it
01:33 rue_bed hmm
01:33 rue_bed 40c/lb?
01:35 katsmeow-afk i paid $13.5 for the glass doors, removed the glass and all steel, and returned the aluminum for cash,,,, the 6 doors cost me $81, i got $22 for the aluminum, so (counting gas) i paid $10 for each 32in wide 6ft tall glass........... does that sound good?
01:35 katsmeow-afk yeas, 40 cents lb
01:36 katsmeow-afk i have a total of 10 doors of glass, plus a stack of glass
01:37 katsmeow-afk 256 watts of cells per door if i cram them up tight
01:39 katsmeow-afk so it was a bad deal?
01:42 katsmeow-afk new glass at Lowes is $13 for 24x36 inch
01:53 katsmeow-afk Lot Of 16 Assorted 1GB DDR2 Laptop RAM Modules $33.50
02:37 rue_bed soundsl ike an ok deal, glass is just everywhere here
05:24 katsmeow-afk glass isn't here, as soon as one human puts it down, another human will shatter it for amusement
05:25 tsmeow-afk regrets she may be cutting a couple of the big sheets in half, to make 32x36 -ish panels that are more easily moved ar
05:28 katsmeow-afk it's like,,, a business can be active for 60 years, never needing to replace a single window, but if they shut down, 100's of windows suddenly shatter
05:28 katsmeow-afk within weeks of me leaving the place in Fla, the windows whee busted out there too
07:14 katsmeow-afk INTERNET: A waste of time. Have a long online argument with anyone who disagrees.
07:19 Tom_itx Yes. No.
07:25 katsmeow-afk Report: Millions Of Courageous Americans Overcoming Media Pressure To Be Thin
07:25 tsmeow-afk waves hi at
07:36 katsmeow-afk “Earth life originated on Mars and was brought to this planet aboard a meteorite,” Space.com reports. The key bits of evidence: certain elements necessary to the creation of life were not “available on Earth at the time life first began.
07:36 katsmeow-afk And so, the theory goes, these substances took “an interplanetary journey after being blasted off their home world by an asteroid impact,” eventually landing on Earth.
07:36 katsmeow-afk Smash cut to three billion years later, and that highly oxidized molybdenum, boron, and let’s say wine and Spotify are responsible for such advanced life forms as . . . Miley Cyrus.
07:39 katsmeow-afk shame the usa media cannot say precisely what "twerking" is
07:39 katsmeow-afk George Carlin would have a field day with that word
07:52 katsmeow-afk "we thought tossing bombs at people would be a practical joke." <<== how it that practical?
14:01 katsmeow-afk i figured out a cheap way to make a piston think the crankshaft throw is moving in an oval instead of a circle, but this works only if it's a crosshead slide system
14:05 rue_house ?
14:05 rue_house no straight piston with linea lisders and a seperate crank arm?
14:05 katsmeow-afk linea lisders?
14:05 rue_house (think locomotive)
14:06 rue_house "cross head"
14:07 katsmeow-afk https://en.wikipedia.org/wiki/Crosshead
14:07 rue_house http://www.petervaldivia.com/technology/mechanisms/image/steam-engine-phases.jpg
14:07 rue_house were both on the same page aren't we?
14:08 katsmeow-afk yeas, plainly on http://www.petervaldivia.com/technology/mechanisms/image/steam-engine-phases.jpg you can see the crank throw moves in a circle
14:08 katsmeow-afk and the engine has a crosshead slide on the connecting rod(s)
14:08 rue_house the shop was so low on .47uf non-electrolytic caps, even off scrap pcb's that I bought 100 from china
14:09 rue_house are you tweeking the crank path to increase torque at bad angles like a bicycle?
14:09 katsmeow-afk what has *always* bothered me with steam and internal combustion engines, is peak connecting rod stress is at peak pressure when the crank throw is pointed right at the piston, with no hope for rotary torque being developed
14:11 katsmeow-afk if peak pressure (in a circular system) is delayed till 10 degrees, you start developing torque from all that pressure, but the volumetric efficency sucks badly
14:12 katsmeow-afk imagine how in gas engine , spark is set at TDC or before, depending on rpm,,, if you lag the spark to 10 *after* TDC the engine will barely run
14:12 rue_house have you seen the unround gear / sprocket thing used to have varrying ratio gearboxes/chain drives?
14:13 rue_house http://www.bandhgears.co.uk/images/elliptical_gear_supplier.gif
14:13 katsmeow-afk yeas, i can't get over the number of moving parts and points of wear in a chain drive tho, after 5000 hrs at 2 tons, that chain has got to be really slack and the sprockets badly worn
14:14 rue_house http://i.ebayimg.com/t/SHIMANO-BIOPACE-ELLIPTICAL-CHAIN-RING-SET-CHAINRING-DOUBLE-42t-52t-VERY-RARE-/00/s/NzY4WDEwMjQ=/z/KXsAAOxyhodRtPv5/$T2eC16RHJIQE9qUHsjyKBRtPv4uK9w~~60_35.JPG
14:14 rue_house they do it on bikes to give you more torque as you start your stroke
14:15 rue_house http://cycletechreview.com/wp-content/uploads/osymetric-ring.jpg
14:15 katsmeow-afk bike is small and short duty, i was thinking 10hp for gennies, and 400hp for pickup trucks
14:16 rue_house ok, just thinking out loud
14:16 katsmeow-afk for 600,000 miles it hasto run 10,000 hrs, and for 2 years as a genny it hasto run 17,000 hrs
14:17 e_house puts genorator on his todo list for t
14:17 rue_house I have to check this out carefully, I dont understand how I could owe the cable company 185
14:17 rue_house I'm sure I didn't miss that many payments
14:19 katsmeow-afk see, the osymetric-ring sprocket works, but not at 400hp being applied to the chains for 1000's of hours
14:19 rue_house given how many chains in parallel?
14:19 katsmeow-afk in the chain, there's 100's of points of wear and rubbing that you cannot oil while in motion
14:20 katsmeow-afk 2, one on each side of crosshead slide, rated 1000lbs continuous
14:21 katsmeow-afk using the eliptic, you can reduce the peak pressure on the whole system, and a long stroke starting at 1000lbs and decreasing linearly to the exhaust point can work
14:22 katsmeow-afk the chain becomes the weak link, and as it stretches it makes wear on the sprocket accelerate
14:39 rue_house OOOOOOh, a year ago they changed it,to pay for my email acount I have to put 4 0's infront of my account numbers
14:40 katsmeow-afk so you have not paid for internet for a year?
14:41 rue_house email
14:41 rue_house my old provider couldn't give me service, but I wanted to keep my email address
14:42 tsmeow-afk
14:42 rue_house they downgraded it to an email-only, but it only costs about $3/mo, so I load it up with like $100 and forget about it
14:42 katsmeow-afk time to send them another $100
14:42 rue_house and I owed $18, so I been working on this payment problem for a long time :)
14:42 rue_house I sent them 118
14:43 rue_house I'm good for a while
15:06 katsmeow-afk http://www.youtube.com/watch?v=fPWuW8kBM5c
15:07 rue_house k...
15:13 katsmeow-afk that much heat is more than enough to keep my downstairs at 75F when it's below freezing outside day and nite, i may as well make electricity from it too
15:16 katsmeow-afk 3400 btu = 1 kwh
15:17 katsmeow-afk my heater for this whole 24x48 ft space is 900watts, added to by the puter(s), sterio, nestbox heater, waste heat off the fridge, etc.,,, it's really well insulated
15:31 katsmeow-afk basically, if i burn enough anything to make half my current winter electricity needs, the waste heat from that is more heat than i need, and more electricity than i need too
15:32 katsmeow-afk a single mantle propane camp light, turned down as low as it will go and still be white lite, will overheat the 16x16 ft bedroom
15:34 katsmeow-afk so the goal is to make enough electricity from that amount of fuel
15:35 katsmeow-afk then the high temperature "waste" heat can make warm water, then heat the nest box, then the rest of the room(s)
15:36 rue_house iirc I have to increase the radiator capacity in the house on my system
15:38 katsmeow-afk ever consider layering up a whole wall with emt , and a $15 fan, and then hiding behind a fake wall? You'd have extreme efficency, and you can prolly get used 1/2 emt for cheap
15:39 katsmeow-afk even 1/2 cpvc leaks btu like mad,, the temperature drop in uninsulated hot water pipe from utility room water heater to the downstair bathroom is stupidly high
15:51 rue_house I have a bunch of copper radiators around
15:51 rue_house and finned copper pipe for hydronic baseboards
15:52 tsmeow-afk
15:54 katsmeow-afk > Incropera and Dewitt's book is very good. I have two copies of it myself.
15:54 katsmeow-afk > argh... and I only have one copy of that book... How can I keep up with you guys? Gonna have to go buy another copy now... <sigh>
16:03 katsmeow-afk kewl, i plugged my house data into a online calculator of such things, and it says my total design btu loss is 7000 btu/hr , so 3400 btu from a small floor heater, and average 8 amps into all other electrical (fridge, puters, undersink 120v instant water heater, etc) is actually what happens irl
16:04 katsmeow-afk oops, bad entry, 5280 btu loss
16:05 katsmeow-afk makes more sense, since i don't use all that stuff 24-7, don't even run the 900w heater 24-7
16:05 katsmeow-afk http://www.builditsolar.com/References/Calculators/HeatLoss/HeatLoss.htm
16:07 katsmeow-afk so a cord of pine should last me 136 days, burning 1.8 lbs of wood per hour, 44 lbs per day
16:09 katsmeow-afk i forget how many pinecones = 1.8 lbs
16:30 katsmeow-afk hmm, it
16:30 katsmeow-afk s now phorpiem
18:02 rue_house yay muffler works
18:02 rue_house I think that most of the raimaining noise is the INTAKE
18:04 Tom_itx if you turn it off the noise will go away
18:16 rue_shop2 :)
18:16 rue_shop2 1/2 or so run, seems fine
18:16 rue_shop2 it'll do in an outage
18:17 rue_shop2 still owe it an oil change tho
19:21 tsmeow-afk points rue to cementboard / hardieboard / durock to make the sides of a sound resistant and bug/rot/fire proof gennie cubby
19:25 katsmeow-afk and the roof, ceiling, drink bar, and maybe even the floor
19:28 katsmeow-afk carpetting is also appreciated in noise reduction , i carpetted the blower even (which is also inside the cubby, out of the rain and snow) : http://designerthinking.com/images/generator-little/IMG_1280m.jpg
19:32 katsmeow-afk the blower intake is behind a baffle, the exhaust hole at the other end is also baffled, so when i have power in a county-wide outage, the neighbors are baffled too
19:36 katsmeow-afk ever since my mom visited, i have not enjoyed that
20:09 katsmeow-afk it is sooooo hot and humid outside
22:38 rue_bed hmm a box
