  1. Strangely we got the printer the next day... vendor on Suk road. bought filament subsequently from same shop expecting fast delivery - nope. Agree.... too much has to come from China these days ?
  2. Hi bought an Elegoo Neptune 4 printer..... came with a little bit if PLA+ filament. bought some from shopee, but taking forever to get here. anyone know where to buy around Bangna ? itching to play with my new toy . Thanks
  3. Going out on a limb here, but xx years back i remember at school welding with MIG and CO2.... or maybe it was just cheaper for students to use CO2
  4. Cheers... lived here for 30 years, and read and speak Thai so no issue there. Yes... looking for someone better than my current guy to do some "precision" work welding 1.5mm stainless steel into little boxes
  5. Sounds like a very farang attitude - everything Thailand is bad. Already have a guy who does 1mm stainless welding and i need precise stuff for a machine, just looking to see if can find better.
  6. Anyone know in Bangkok where i can find a good TIG welder and / or a company that can make 2 stainless steel boxes about 120 x 30 x 130 mm from 1.5mm sheet? Thanks. Working on something which needs some precise work
  7. Thanks !.... not a fan of mesh, prefer hard wired back haul. Really appreciate both you inputs.
  8. Sick of <deleted>ty internet in the house, extenders are crap. would like to pull LAN cables from router into the house to ie bedroom and other rooms we us alot and put an AP. Anyone know of a reasonable company in BKK who can do it ?
  9. Probably best I can find is this https://calcdevice.com/forced-convection-of-inner-pipe-surface-id130.html
  10. Thanks... seen that one too..... but this does not cover 17" pipe, stainless steel, nor speed of air nor thickness of pipe
  11. Thanks.... the question is not what's the exhaust temp of the air, rather how much heat loss would go through the pipe - realise they are both linked
  12. Thanks - been on that web site and a gazillion others. the trick is the Hconv constant Hot air, 170 Deg C and 8 m/s
  13. My head is spinning - anyone good at heat transfer calculations... ? Home work is tube / pipe 0.45m diameter, and length 1.5m, wall thickness 12mm Hot air 170 Deg C blows through 8m/s Stainless Steel How many Watt ( What ) can transfer through the pipe
