00:05 rue_house that took me a minute to figure outm cool concept
00:09 rue_house http://www.joules-project.eu/Joules/images/technologies/cycloidal_propeller_also_called_voith_schneider_propeller.jpg?pfdrid_c=true
00:09 rue_house doing it in water makes more sense
00:58 katsmeow-afk <cough>
01:01 katsmeow-afk in http://rotoplan.narod.ru/IMG/img033.jpg , the blade on the bottom is upside down, because it's a curved airfoil
01:01 katsmeow-afk if they insist on a curved airfoil, allthe blade roots must be mid-blade, and flipped over at the bottom
01:01 katsmeow-afk doing so witll make a ton of turbulence
01:02 katsmeow-afk it might make more sence to use it as a paddle on thebottom
01:03 katsmeow-afk they may be better than a plain bare prop, but like a eggbeater vertical axis prop, they suffer other losses somewhere
01:04 katsmeow-afk more and more high hp props are "ducted fan" types to take advantage of blade tip effects
01:05 katsmeow-afk if you look at pics on https://en.wikipedia.org/wiki/Voith_Schneider_Propeller , the true version of those do not have atrue airfoil blade shape, and the root is centered, so no blade in the assy is optomised for anything
01:09 katsmeow-afk ergo , http://rotoplan.narod.ru/IMG/img033.jpg isn't going to scale up even if it works at all
01:09 katsmeow-afk and going to a true Voith_Schneider_Propeller blade isn't going to help
01:12 katsmeow-afk see http://voith.com/en/s2_am_screenshot_iVSP.jpg
01:13 katsmeow-afk the blades are elongated teardrops, they are shaped just enough to handle the side forces on the blade and slide thru the water easily
01:14 katsmeow-afk they use no bournulli effects at all, like aircraft wings and props do
01:15 katsmeow-afk as "paddle blades" you can turn them in any direction, and use them exactly like an oarsman uses a oar to steer a canoe with
01:15 tsmeow-afk considered these things decades
01:17 rue_house :)
01:26 katsmeow-afk looks like the usa navy got rid of all their Voleriths in less than 10 years after commissioning, and couldn't give away 4 (5?)of them and scrapped them
01:28 katsmeow-afk idiot .gov site thinks i am using Gecko browser
01:29 katsmeow-afk they sent something that FF is refusing to display
01:33 tsmeow-afk is currently seding User Agent : Mozilla/5.0 (Windows NT 5.1; rv:36.0) Gecko/20100101 Firefox/
01:38 katsmeow-afk poor ebay seller, he has several auctions/buynow for ADV7120KP30 , which he is advertising as 80Mhz, but those are only 30Mhz
01:38 katsmeow-afk he does have some ADV7120KN50 , but wants 3x as much $ for them
02:02 katsmeow-afk "Hyland's Restful Legs does not treat Restless Legs Syndrome. "
02:03 katsmeow-afk i am guessing their Super Vision pills have nothing to do with the eyes?
02:06 katsmeow-afk Uses: Temporarily relieves symptoms of the compelling urge to jerk or move legs to relieve sensations of itching, tingling, crawling, and restlessness of legs. ....does not treat Restless Legs....
02:06 katsmeow-afk In homeopathy, arsenicum album is a solution prepared by diluting aqueous arsenic trioxide generally until there is little or no arsenic remaining in the solution.
02:08 katsmeow-afk Since the arsenic oxide in a homeopathic preparation is normally non-existent, it is considered generally safe, although cases of arsenic poisoning from poorly prepared homeopathic treatments sold in India have been reported.
02:08 katsmeow-afk it is extremely statistically unlikely that any pill contains even a molecule of the original arsenic used.
02:11 katsmeow-afk any time i see "cuprum metallicum" listed as an ingredient, i disregard the entire paper as bs

03:25 tsmeow-afk wonders if zhanx's last nick is

05:55 katsmeow-afk guy spent $2 million making a submarine , he figures he can charge $100 per person per dive , i figure if he does 2 dives with 2 people per day 200 days per year, he might break even in 25 years
05:59 katsmeow-afk not counting replacing the batteries every winter, the CO2 recycler reforming after each day's dives, diesel fuel, hull cleanings and paint, the required safety boat and crew, pilot's wages, insurance, dockage for sub and safety boat, etc etc
06:14 katsmeow-afk ----
06:14 katsmeow-afk The genes that have gone airborne are contained in dried fecal matter that has become dust and gets picked up by winds as they whip through the stockyards.
06:14 katsmeow-afk The Texas Tribune reported that representatives from the Texas cattle industry (estimated to control around 14 million beef cows) criticized the study, saying it portrayed the airborne bacteria as overly hazardous to human health.
06:15 katsmeow-afk the study estimating the total amount released by cattle yards in Colorado, Kansas, Nebraska, Oklahoma and Texas exceeds 46,000 lbs.(21,000 kg) per day.
06:15 katsmeow-afk -------
06:15 katsmeow-afk nah, breathing in 46,000 lbs per day of cow fecal matter isn't harmful at all !
06:38 Tom_itx that's why it's windy here most of the time
06:50 katsmeow-afk to carry away the cow pies?
07:04 katsmeow-afk put up a line of old conventional windmills from you to the gulf, to assist the tunnel digging, and then the pump the desalinated water inland from the gulf
07:13 tsmeow-afk imagines Tom's kids, grown up, and with kids of their own, and try to figure where the water will come from for them to drink and grow food
12:43 katsmeow-afk Tom, can you explain "collet extension holder" to me?
13:56 Tom_itx i'm guessing a tube with a collet holder on the end
13:56 Tom_itx i have one
13:56 Tom_itx mine is 1/2" diameter
13:56 Tom_itx for small bits
14:02 Tom_itx http://ecx.images-amazon.com/images/I/31RPR3ABNsL._SY300_.jpg
15:38 any15805052 how does it release the bit?
16:21 Tom_itx spanner wrench
16:23 Tom_itx http://www.lyndexnikken.com/store/pc/catalog/er-spanwrench_1609_detail.jpg
16:23 Tom_itx or
16:23 Tom_itx http://cdn2.bigcommerce.com/server2900/87c84/products/55/images/134/IMG_0453__53196.1405338495.1280.1280.JPG?c=2
16:25 Tom_itx these fit inside for the tool: http://www.knuth-industry.ru/assets/images/product/zagim-instrum/106050_hpt_fs_1.jpg
16:26 Tom_itx many different 'series' of collets
16:28 Tom_itx ER8, ER11, ER16, ER20, ER25, ER32, ER40, CAT40, CAT50 etc
16:28 Tom_itx our machines used 40 and 50 taper
16:29 Tom_itx and as you know bridgeport used R8
19:23 any15805052 so you are saying the nut on the end of http://ecx.images-amazon.com/images/I/31RPR3ABNsL._SY300_.jpg clamps the collet inside, but none of those wrenches look like they fit that nut, that looks like a common nut for a common wrench
19:23 any15805052 you take the nut off entirely to drop the collet out? what if it's stuck?
19:23 any15805052 what if the bit is stuck in the collet?
19:25 any15805052 i am thinking of the hollow spindle, you can drop a rod down inside to knock stuck things out, and the collet holder is pulled up by a thinwall tube inside the hollow spindle
19:26 any15805052 or the collet itself is threaded
19:27 any15805052 http://www.hiwtc.com/products/1c-3c-5c-16c-20c-25c-collet-14873-37083.htm
19:46 y15805052 throws an url at rue and Tom : http://www.myvirtualnetwork.com/mklotz/
19:56 any15805052 Knowledge must be shared or it lies dead in the mind.
19:57 any15805052 "Janet Reno killed more children at Waco with Bill Clinton's permission than Adam Lanza killed at Sandy Hook." <<== umm, ouch
19:57 any15805052 the bank gave the town Adam Lanza's house and property, and they bulldosed the perfectly good house
20:44 Tom_itx hollow spindle is bridgeport R8 style
20:45 Tom_itx that is with the 'drawbar' screw
20:46 Tom_itx modern cnc's use retention knobs and a mechanism to grab it to hold the collet in
20:47 Tom_itx some designs use stacked cupped washers as springs as load to hold the collet in and released with hydraulic or air cylinder
20:48 Tom_itx others use 3 stage cylinders to get the pressure
20:50 y15805052 chose C5 collets, but has yet to get a collet holder for the end of the spi
20:51 any15805052 i al so sore, and sore,, and i'm sore
20:54 any15805052 moved dirt, moved the boat rib form from it's storage to outside, and then back inside again, moved the 10ft of 4ft dia tube out from under the garage roof, and set up to move the old center hull stern (8ft of 7x8 1/4 plate box, with end) 4ft back , to give me more room around the pontoon deck
20:54 Tom_itx that's it?
20:55 Tom_itx :)
20:55 any15805052 yeas
20:55 any15805052 had to stop because 1) i was sore, b) it was dark, and iii) i is sore
20:57 Tom_itx rue should look at the gcode generator
20:58 any15805052 you see that page of software
20:58 Tom_itx that's what i'm looking at
20:59 any15805052 is 5C and C5 collets the same?
20:59 Tom_itx i dunno
21:00 Tom_itx afk
21:15 rue_shop3 well, whats the 5 for and whats the C for?
21:16 rue_shop3 Tom_itx, what gcode genorator
21:17 any15805052 [19:26] * any15805052 throws an url at rue and Tom : http://www.myvirtualnetwork.com/mklotz/
21:17 any15805052 that gcode gennerrraoottorrrr
21:20 rue_shop3 aliens: swat bug on alien, resulting in bug flying off and alien unconscious on ground....
21:27 Tom_itx the one written in c
21:28 Tom_itx you know... the portable language
21:31 Tom_itx too bad all they give you is the exe
21:31 Tom_itx you could contact the guy though
21:50 any15805052 road grader attachment for your mowerbot : http://www.homemadetools.net/uploads/79550/mini-road-grader.png
22:48 any15805052 good dog, i am sore
22:55 rue_shop3 haha thats cute
22:55 rue_shop3 I want to make one
22:56 any15805052 you see the mowerbot img on my site?
22:57 any15805052 http://designerthinking.com/images/MOWERBOT.JPG
22:58 any15805052 think of it as a power unit, which you can plug in anything, attach anything, not just a mowerdeck
23:00 rue_shop3 hahaha
23:00 rue_shop3 big loud, chrome, must be american made
23:00 any15805052 snow plow, frontend loader, crane, etc
23:00 rue_shop3 mine is small, electric, quiet, must be canadian
23:01 any15805052 put reverse 3-point hitches on all sides of it
23:03 any15805052 stump grinders, dump buckets, log skidders with splitters, engine hoists, etc
23:03 any15805052 make it articulated frame steering, not skid steering, so it doesn't rip up lawns
23:07 any15805052 attach a grocery cart and send it to the store (electric drive inside the building)
23:10 any15805052 cozy it up to a genny during storms
23:11 any15805052 have it chase bears while meowing loudly
23:12 any15805052 rotary drill post holes, be a backhoe, pull a trailer
23:29 any15805052 .............................................
23:35 rue_shop3 24 guage
23:36 rue_shop3 ok and I figure 16A peak
23:36 any15805052 ?
23:36 rue_shop3 the ground connections on the motor drivers, I dun had an assembly oversight
23:36 rue_shop3 two 24s are 21
23:36 rue_shop3 four 24's are 19
23:37 rue_shop3 er 18
23:38 rue_shop3 6"
23:38 rue_shop3 .003 ohms
23:38 rue_shop3 16A
23:39 rue_shop3 root@blackie2:/files/doc/drafting/gearlib# ohm -r .003 -i 16
23:39 rue_shop3 Wattage is: 0.768000
23:39 rue_shop3 Current is: 16.000000
23:39 rue_shop3 Voltage is: 0.048000
23:39 rue_shop3 Resistance is : 0.003000
23:39 rue_shop3 .7w, igkgh
23:39 rue_shop3 so, right now...
23:40 rue_shop3 root@blackie2:/files/Installs/linux/Slic3r/bin# ohm -r .013 -i 16
23:40 rue_shop3 Wattage is: 3.328000
23:40 rue_shop3 Current is: 16.000000
23:40 rue_shop3 Voltage is: 0.208000
23:40 rue_shop3 Resistance is : 0.013000
23:40 rue_shop3 brutal, I'm glad its only pulsed current
23:41 any15805052 the cheap wire i got for power is 16-3 , 1 is + , one is - , one is feedback , so my current sense "resistor" is ~6ft of 16awg
23:42 any15805052 8amp peak
23:42 rue_shop3 yup
23:43 rue_shop3 http://ruemohr.org/~ircjunk/tutorials/elex/cursense/main.html
23:43 any15805052 4 ohm / 1000 ft
23:43 any15805052 6ft = .024 ohms
23:44 any15805052 333 v drop
23:44 any15805052 wth
23:44 any15805052 .192 v drop
23:45 any15805052 1.536 watts per power conductor
23:45 any15805052 3 watts per cable
23:45 any15805052 1/2 w per foot
23:46 rue_shop3 hmm, according to this I need 20 24guage wires to reduce the voltage drop to .01V
23:46 any15805052 .384 v total drop at 8 amps, hopefully that won't be a long-lasting situation
23:47 any15805052 gives me max of 1.016v drop inside the charger
23:49 rue_shop3 hmm this says to use 12 guage wire
23:49 rue_shop3 well its ground loss, so, ok
23:50 e_shop3 gets a piece of solid 12 awg
