  1. You will be better buying a small generator. Also no details about electrical load - 1500W peak or average? Quick math shows 2 x 105ah batteries(12Volts) have 2.52 KWh energy at full discharge but you never go deep discharge or else you will buy lots of batteries and they are not cheap. If your load is 1500W - this means 12KWh in 8 hours, your batteries are far from it.
  2. You are right - stupid me... Mine was tight from factory and haven't notice is adjustable. Thanks for this Batian!
  3. The same on mine - took some muscle to release the gun. A good idea will be to polish a bit the nipple.
  4. Unfortunately Porlex(mini or tall) is not espresso capable - it is good for brew only. You should look for Kinu M47 or Feldgrind range if you want a manual grinder.
  5. Oolong, Rooibos, Masala Chai to mention a few
  6. That will be static balancing and you will need to disassemble the unit - not practical. I will go different way with dynamic balancing to check whole unit: motor+cooling propeller+exhaust impeller Don't know if effort will justify the results - Dalian unit is pretty "silent" as it is Sorry for being bit off-topic in Dave thread - also in RC everything(planes/cars/copters)
  7. Well, I am planning to check the balancing on mine at some point when I will get a bit of spare time and I will share the results. From the sound of it, there is room for improvement. Nevertheless you need a lot of patience to do it properly with household tools...
  8. It depends on manufacturer and the cost of the product - on simple cheap fans you will not find it For a good product, manufacturer finds a way to balance the propeller or impeller either by adding weights (similar to car wheels) or removing some weight on the opposite side by polishing or cutting or drilling a bit of material Balancing is extra cost but it pays off - lower noise and less stress/longer life on bearings. Frankly I was a bit surprised to find one on Chinese unit
  9. Quick photo to show the balancing clip on impeller - one "heavy" clean can remove it without noticing something was there
  10. One thing to pay attention when cleaning the fan: the impeller has a balancing part(metal clamp) on one of the fins - it is good not to remove it or better to mark it's position in case you will need to put it back.
  11. If you can get them, I would recommend any of the red ones from wine valley in Romania. Couple of weeks ago I was conducting on-site "research" and time passed too fast:whistle: Random example: http://www.lacertawinery.ro/en/ they might ship abroad
  12. Looking good - really enjoying to see the progress Why only 1 hole? I am assuming it will be for the roaster - how about room ventilation? Or you are planning to share it between the roaster and room ventilation?
  13. @ Hasi - could you post a roast diagram as well? What I did noticed on mine is that increasing the air flow is also increasing the heat transfer between heating element and the beans. Depending on the how you look at, for a short time, increasing airflow raise the ROR then it goes down ending back on initial curve(a bit lower actually) - kind of S curve.
  14. I would suggest to go to a service center for a general check. I had this grinder years ago and didn't like it, sold it after 3 months - too many variables to get consistent result to my liking. If you decide to fix it yourself, couple of points that might help - you should search the net since a lot of fixes are documented. * I can't get an even espresso-sized grind, even at finest settings – it comes out with lots of bits of white "chaff" mixed in * the grind doesn't drop nicely into the portafilter any more, but flies all over the place You need to clean it deep by disassembling the main components - white stuff is remaining cleaning "solution" recommended by manufacturer(Grindz) that accumulates on exit path behind plastic anti-clumping piece * the settings are not reliable known problem caused by design and specifically calibration screw support that it is getting loose and needs to be re-seated and grinder calibrated to your liking As for burrs, they are ceramic - unless you got some small stones within coffee beans or other foreign objects, at 40kg beans, you shouldn't need to change then - only clean them. Good luck!
  15. Just got a gift from my wife:D Hopefully arabica
