00:17 orlock everybody knows the only thing in california is biker gangs
00:23 DagoRed and legalized weed
00:50 MrCurious no... thats colorado and washington

08:59 robotustra GuShH: are you alive?
08:59 robotustra finally
08:59 robotustra how is your health?
09:16 GuShH robotustra: getting better
09:16 GuShH :)
09:26 robotustra good, I'm drawing corexy in the evenong
09:26 robotustra ning
09:30 GuShH robotustra: looking to buy a power hacksaw :/
09:30 GuShH one of the smaller onest
09:30 GuShH used, because they were all cast iron, nice and rigid
09:31 GuShH probably requires restoration but I'm sick of the chopsaw
09:33 robotustra should buy aluminium extrusion 20x20
09:33 robotustra 7-8 meters
09:37 soudeur the kerf on powered hack saws is pretty large, be better off with more conventional horizontal band saw
09:38 GuShH robotustra: depends on where you live comes in 6 meters lengths
09:38 GuShH usually (20ft)
09:38 GuShH same with steel, not so with brass
09:39 GuShH usually 4M
09:39 GuShH or 3M, depends... not sure why
09:39 GuShH steel is usually 40ft for transport, then 20ft for resale
09:39 GuShH at least structural and such
09:41 GuShH seems most of the stuff around here is 20ft right out of the mill, you can tell by the hot cuts (shear cut while it's still hot, deforms the ends slightly on solids)
09:43 GuShH soudeur: depends a lot
09:43 GuShH mostly on the type of blade used
09:44 GuShH bandsaws cost more to run / maintain, they are bigger (we're talking metal cutting saws here, not for wood)
09:44 GuShH I have a space constraint.
09:44 GuShH that's why I'm looking at the older, smaller power hackasaws like these ancient things http://i.imgur.com/TRXECzT.jpg
09:45 GuShH oh by kerf you meant the tooth set?
09:47 GuShH all I see are "fine" and "coarse" either HSS or bi-metal
09:47 GuShH if you have it setup properly they leave very little burrs with most materials
09:47 GuShH that can't be said for abrassive cuts.
09:48 GuShH ideally a hydraulic wet bandsaw would be best.
09:48 GuShH horizontal
09:49 GuShH they are massive by comparison, a wet power hacksaw can be had for less money and space, they are slower but if you want speed that's another issue.
09:50 GuShH problem with the one in the picture is... it's a dry one
09:51 soudeur kerf does not mean tooth set
09:51 soudeur and by tooth set
09:51 soudeur you mean pitch
09:52 soudeur the size constraints of a horizontal band saw are no more than that of a powered hacksaw that accepts the same stock sie
09:53 soudeur size
09:54 soudeur not to mention the longer blade life out of a band saw blade as you are have multiplied your cutting surface 3 or 4 times
09:56 GuShH soudeur: I'm not buying a chinese piece of shit, the only bandsaws worth buying where I live cost a small fortune, they're industrial wet type with hydraulic feed.
09:56 GuShH elitism does not apply for the homeshop
09:56 soudeur the small jet bandsaws out perform the old powered hacksaws
09:56 GuShH bandsaws take longer to replace the blade, the blades cost more
09:56 GuShH jet = china shit
09:56 soudeur haha
09:56 udeur shakes
09:57 GuShH bandsaws take longer to setup as well, specially the china shit won't track nor cut straight.
09:57 GuShH soudeur: jet IS rebrand china.
09:57 GuShH it's not US made.
09:57 GuShH their power tools are made in china, generic, rebrand.
09:57 soudeur out of the box the test piece for most jet horizontal band saws is within 0.003"
09:57 soudeur your powered hacksaw will not hold that
09:57 GuShH when you purchase at china you are given the choice of colors, option, quality and logo.
09:57 soudeur nor will the extra kerf amount be worth it
09:58 GuShH soudeur: who gives a shit, the parts are machined afterward
09:58 GuShH it's an intermediary process.
09:58 udeur bl
09:58 GuShH you always cut oversize, you always machine all faces.
09:58 soudeur you always do this to metal you cut?
09:58 soudeur always?
09:58 soudeur always?
09:59 GuShH yes
09:59 soudeur haha
09:59 GuShH you expect a flat surface out of a saw?
09:59 soudeur yeah rock out with your piece of shit homie
09:59 GuShH soudeur: go play machinist somewhere else.
09:59 soudeur i am not sure i have to play at anything to be honest
09:59 GuShH JET is all china shit, deal with it. your country has no industry left.
09:59 soudeur however as you do not even know the simple terms associated with using a saw
09:59 soudeur a *saw*
09:59 GuShH you consume chinese shit.
10:00 soudeur you seem to be the one playing
10:00 GuShH English is not my primary language
10:00 GuShH sit on it.
10:00 GuShH ignored for not being helpful, cunt.
10:00 soudeur thats fine a lot of my coworkers do not speak english as their first or second language they can still converse intelligently about fabrication
10:00 GuShH fabrication is what wetbacks do
10:00 GuShH now ignoring.
10:01 soudeur well i reckon that makes you a wetback with your antique powered hacksaw unfortuntly
10:03 GuShH still laughing @ fabrication ... ie. welding and grinding, that has nothing to do with machining and precision work. your idea of precision is having a jig on a table and hammering shit together, that's what fab is all about.
10:03 GuShH a table that isn't even flat by any standard.
10:03 GuShH if you ever show a fabricator a micrometer, surface gage or any instrumentation they stare at it like a fucking monkey
10:03 GuShH which they are.
10:07 soudeur more so it is the final stage of the early stages of metalworking e.g. machining
16:19 Hyratel1 my brother is a fabricator-designer <.<
16:35 io___ any computer hardware expert here?
16:39 Hyratel1 io___, thats a vague query. be more exact
16:39 io___ ok
16:40 io___ My cousin has old computer 10 years back. Computer is assembled i.e. made up of different different parts from different brands.
16:40 io___ Computer was working good since last 9 years. It is no more working since last 1 year. My cousin called up some hardware guys/experts in the city/locality. All of them may have tried their best to start computer; but they failed ultimately & some of them suggested to replace X(may be motherboard=mobo),while other suggested to replace item Y(may be RAM). But
16:40 io___ we are not sure where is exact fault? This excercise is only for identifying which parts are damaged. (so that we can replace them & make computer functional again)
16:40 io___ So my cousin handed over computer to me. Actually monitor was CRT hence bulky, i only took CPU cabinet(fitted with 1 switch for power on & another for reset & LED & small speaker) +keyboard+mouse+motherboard(processor/CPU fitted)+cables+hard disk+ram+PSU(SMPS) from my cousin's home. PC doesnt have any graphics card/other addon cards/games cards.
16:40 io___ Brief Specifications are as under
16:41 io___ 1. ASUS motherboard K8V-MX
16:41 io___ 2. CPU AMD Athlon-64
16:41 io___ Tools i have
16:41 io___ 1. Multimeter
16:41 io___ 2. LEDs & resistors (if required for any kind of testing)
16:41 io___ All parts are isolated(except CPU) when i received from my cousin.
16:41 io___ what i did
16:41 io___ 1. Overview/visual checking of all major parts like PSU, mobo, RAM, terminals/pins etc.. all found ok. Capacitors are also intact.
16:41 io___ 2. Tested PSU indenpendently using paperclip method & result found satisfactory. PSU fan started. (when Green & black wire are sorted)
16:41 io___ 3. Checked CPU cabinet speaker resistance; multimeter shows 0.02 ohms
16:41 io___ 4. Setup: PSU connected to mobo ( via 2 cables: 20 pins & 4 pins). CPU speaker connected to mobo(2 pin thin cable) & connected 1 RAM stick & connected CPU cabinet speakers. Then switched on Mains power supply.
16:41 io___ Result:No beep/sound & Yellow LED on mobo working/ON.
16:41 io___ I guess there may be problem with speaker or mobo or CPU.
16:42 io___ sorry too long story Hyratel1
16:42 Hyratel1 tl;dr
16:45 io___ what is that?
16:47 DagoRed too long, didn't read
16:52 io___ in sort i need to find a mobo for my CPU. DagoRed
16:52 io___ can you help me?
16:53 io___ mostly people says mobo is faulty/failed & CPU doesnt fail.
17:06 DagoRed I don't have time to help you io___.
17:06 DagoRed It's not that hard, you have the current motherboard so find a new one with the same socket for starters.
18:42 poli GuShH: so how are things going my argentino friend?
18:46 GuShH dunno
18:47 GuShH how are things going my brasilero friend?
18:47 ShH sh
18:47 GuShH I think it's all the same if not worse.
18:47 GuShH generally speaking
19:34 poli GuShH: well macro stuff is all screwed up here too. Latin american populism.
19:35 poli GuShH: Did you build a reprap?
20:33 GuShH poli: on it, kinda paused again, had pneumonia.
20:34 poli GuShH: I just started researching a synergic technology
20:35 poli GuShH: ever heard of contour crafting?
