Laser cutting heads, nozzles and extensions- hardware

I have been accumulating tubes and nozzles in the hope of being able to have a dedicated tube for 2" and 2.5" lenses with nozzles to work with each-easy exchange in other words. I have also always questioned my laser head as when I installed the Ruida dsp, my limit switches were not adjusted and I *really* crashed at high speed. So this is what I have so far- may be of interest to someone. First pict is the head on my machine, second it a tube I bought from china and a complete head assembly, also from the Chicoms. The 3 tubes are all slightly different diameters, so none will interchange. The nozzles and extensions [ .433" or 11mm] all have the same threads, so they will interchange and by using one extension on my present nozzle I will be able to use the 2.5" lens I have lately received. I can provide more info on sizes and where purchased if anyone wants it. Gene

I ordered one, advertised at 25mm tube- which is very close to the tube in my large machine- but about a half mm larger as it turns out. Nothing ventured, ya'know how that goes. Anyway the tube is threaded at both ends for the lens (and it turns out mine is too- have taken it out countless time in the last year) and the threads are the same on both tubes so I can use my old tube. The upper position is about 100mm or 5inches so I am not sure how useful that will be. Anyway- we know more now, right? Gene
