  1. hello, I am new here and am just looking for a bit of advice from the knowledgable. im shortly going to be making a 2 x 72 belt grinder. I looked at a few treadmills but they only have smaller 1 kw motors, and I think I really need closer to 2kw, or at least 1.5 (advice taken on this), but im of the thinking if I get a bigger motor it should have more torque im looking at a 3hp, 2.2kw single phase one.. what do you think? good idea or overkill? I was also looking at vfd's and to be honest I don't really have a clue on these. ive found one (not sure if im allowed links or not so I wont - don't want to upset the management on my first post do I?) It says 220v 12A PWM variable frequency drive speed controller for 2.2kw ac motor. would this be suitable? I also notice that most VFD's are for 3 phase, does this convert 3 phase motors to run off single phase then? like I said im clueless about electrics. Also while im here, what about potentiometers? can these be used? # #Any advice appreciated or if you could point me in the direction of some sort of guide, that would be great. im in the uk for electrical advice. Thank you.
  2. Useless information alert - the design of the celtic knot dates back to the 6th century, and originated in Northern Italy/ southern Gaul (France), before appearing in Ireland and Scotland in the 7th century, so its definitely public property. The Sgian Dubh looks fantastic, id proudly wear it with my kilt.
