    Advice sought re: 3D printer purchase

    Mike, Ken here in Hobart. Like you I wanted a 3d printer to print stuff with, not mess around with the tech., so after much looking & reading I bought a Prusa I3 Mk3S+ and have had good experience with it for the last 6 months or so. I have printed off a lot of things, both for me and also...

    Heat treating high alloy and high-speed steel tools

    To add to Henniel's safety warnings re. liquid nitrogen, suffocation by nitrogen gas is quite insidious as the brain only reacts to an increase in carbon dioxide, NOT a reduction in oxygen- hence there is absolutely no warning of suffocation by excess nitrogen in the air- one moment you are...

    Odd Camshaft design idea

    I served my time as an engine fitter in the RAF, where we did all the same sort of things, filing large lumps of metal in to smaller ones and generally learning how to use the basic hand tools in the approved manner- it has stood me in good stead in the (rather too many) years since- except for...

    Hello everyone

    Welding a copper boiler?

    Brian D, fyi there has been a AALS (Australian Association of Live Steamers) duplex stainless steel boiler code since 2010- http://www.aals.asn.au/AMBSC/AMBSC_Code4.htm I would think a boiler built to that code should be acceptable in most places. Ken.

    Hi Paul, I have a couple of questions about supergerbil. Is it possible to get a 5-axis board without any of the plug-in drivers?- I have a number of them spare now and really don't need any more. Are all the supergerbil boards the same except for the number of plug-in drivers supplied? Is...

    I also would like weekly or even monthly, daily is just too much, there is not enough new information.
