![]() ![]() Please note – Northwest Guitars is not responsible for paying these taxes or fees, and it is solely the customer’s responsibility to be aware of these extra costs, and paying them. ![]() They will also, most likely, add an additional handling fee. VAT will however still be paid once the goods arrive into the country of receipt – this will be raised and invoiced between the courier and the customs office in your country. We no longer charge VAT to any customers ordering from within the EU and as such, any VAT/VIES exceptions are no longer valid. On January 1st 2021 the UK left the European Union – and this effects how Northwest Guitars now interacts with our European customers. A 5% incremental increase over the pound–buy in pounds and sell in Guineas gives you a 5% profit.VAT and Import Duty Changes for EU Customers. Then, returning to Imperial, the size is specified (without further rounding) in inches (3-4 significant digits, which looks weird until you realize that the fasteners are metric). Both the diameter and the pitch decrease geometrically by multiplying the 6mm X 1 mm pitch of the standare #0 size by 0.9 (or 10% smaller), and then rounding off to two significant digits in mm. ![]() This is unlike a range where each larger size increases by, say, 1/16 inch. These are rounded off to two digits.īy providing a geometric increase in diameter, the BA range is covered uniformly, with each larger size being the same percentage stronger. That system (RETMA) provides for a geometric sequence of values so that the increase from one to the next is some percentage (common series are 20% and 10%). The logic was the same as is still used in determining specs like resistor values in ohms. Next, unlike many other systems it used pure logic to determine the range of smaller sizes, ranging from #1BA to #25BA. You can specify them as 0BA if you want to confuse people just for fun. That’s the common metric size used today. The basis of the system is the largest fastener, #0BA, which is 6mm X 1mm pitch. ![]() Whilst looking up the BA specs, I was reminded of how cool the BA system was, and how ingenious the Brit engineers were back ca 1900 when the system was introduced.įirst, it anticipated metrication. With no hammer handles in need of polyurethane varnish ( ), I just amused myself by tapping a thumb screw with my #8-36 tap and confirming that if fits the stud on an early Smiths gauge. ![]()
