content: Hi all,I've recently acquired a Metcal QX2 rework station but i need to get some nozzles for it - does anyone know a source for these that aren't stupid prices? I've seen some nozzles for £150 +! Failing that, I'm thinking i might be able to adapt some cheap hot air gun ones from Aliexpress...Thanks in advanceMatt

content: What's the outer diameter where it inputs into the end of the heating element tube?I ask, as I'm wondering if Quick's NK series nozzles will fit (I don't have a proper caliper, but I'm measuring 22.5mm on mine using a stainless steel engineering ruler). They're rather well made actually, and not terribly expensive either (no where near what Metcal's nozzles sell for).NK Series Nozzle Datasheet(.pdf).Somerset Solder&AMSboth sell Quick in the UK, so they should be able to get them for you (also look for the 861DS; usually the sellers I've seen in the past were located in Poland). Maybe even eBay, if you can get them shipped from a US seller.FWIW, I've been able to solder/desolder anything I've come across just using the 3 round nozzles that were included. You can buy or make shields to protect nearby components if need be (JBC shields).Basically, theyborrowedfrom Weller's nozzle design methodology, but offer them at a fraction of Weller's prices.

content: I might see if i can source a second hand nozzle (i've seen one for £35 on eBay but its in the states) at least then i'll have a reference to what the dimensions should beThanks for the links - most useful

content: Quote from: mattb on May 31, 2016, 03:11:00 pmA nozzle would be the easiest way to measure, but can't you measure the metal tube's diameter where it contacts the nozzle?On the Quick models that use the NK series, there's the main metal tube and an additional collar that's fitted around the end (tube inside a tube). Which leaves just enough of a gap between the two tube diameters (inner + outer) to hold the nozzle by friction (gap is ~1.0mm).If measuring by this ^ method isn't feasible, you'd be cheaper to just order an NK series and try it. Shouldn't be anywhere near 35GBP, as they go for under $3.00 here (N3125for example).Probably faster too.

content: Thanks - your right - i should be able to measure the tube and see if it fits. The NK series do look pretty similiar

content: just to follow up on this... they are 35mm diameter nozzles on the metcal... huge!

content: Quote from: mattb on June 07, 2016, 12:02:34 pmThat sucks.Your situation reminds me why I skipped a used Pace hot air unit in very good condition I dearly wanted. The cost of spares & accessories were expensive, such as $400 for a heating element. Yet the entire station was for sale for ~$200. Nozzles go for ~$60 each just for simple round ones.Hope you stumble across what you need on the used market for something more reasonable than 150GBP per.

content: im thinking i might have to turn an adapter on the lathe to take the cheap nozzles and fatten them up
