    As another customer of Marcus's as well as running a research shop that does a lot of weird parts, I can attest to the fact that when your parts get tricky and you need them in onesie twosies, it's...

    You might ask if it would be a good option, because it will be faster, to use a 9 degree per side tapered end mill from Harvey tool or elsewhere. We make thermal cycler blocks and related components...

    This sounds similar to what we went through although this stuff is super confusing. I'm going to relate this story in case it is helpful to anyone. We have a TRT160 on a VM-3, which is big enough you...

    I would very much vote for a CNC tool room lathe even if all you do is onesies and repairs. That's what we do most of the time and our 2007 TL-1 has been great. With a bit of experience you can pick...

    Waterjetting laminates is generally fine provided you can start the jet off the edge of the material, come in and cut around the part and end without having to piece the material. Or if you do it...

    We have discovered a condition we call, "the stupid hour" which typically happens when you work late and get tired. An example is when you're water jetting prototype sheet metal parts and then bend...

    Interesting. What are the other layers in the lamination? We've waterjetted solid tungsten fine although it's relatively slow.

    Also don't forget his successor Ben Rich and his excellent book Sunkworks, which should be read on Kelly Johnson day, which by the way, should be a national holiday.

    Flew Ft Meyers-Toronto-Vancouver on Thursday-Friday and it was pretty normal, other than a 12 hour Air Canada delay for special Air Canada reasons. I think it's going to hit harder though in the next...

    We got the auto doors on our VM-3 without specing them as well in late 2018, and they are nice. It's motivation to find high volume jobs for which you then need to get a robot arm to feed the machine!

    When you say laser etched do you mean laser engraved? Laser engraving is very shallow but you could either engrave after paint, or even more pro, engrave on black oxide.

    A quick note, the best wooden boat builder on YouTube, Leo Gooden of @sampsonboatco (instagram) just took delivery of all his deck beams via a delivery by @thepinkfireman. They're looking for a load...

    Can you avoid flat head screws and use something like flanged round head screws, like McMaster 90399A247 or use countersink washers with oval head screws? It's common practice for mounting sheet...

    i wonder if the working version actually had the curved cylinder bores. You could imagine if there was a little radial freedom at the piston's connecting pin the cylinders could be straight. Thanks...

    +1 for Igus. They sell solid stock of their proprietary bushing materials which have data sheets and from which you can make whatever you want.

    We have in house powder coating at a small scale and just sand blast everything first. The powder coat never fails though even then you need outdoor paint for outdoor applications. (Ask me how I...

    I posted this in our new machine day thread but will post it again as it's neat to see others converging on the 5+3 setup. The new TRT-160 here is so compact you get all kinds of room remaining on...

    My friend Brad just opened up Nook in the Shipyards (for you non-North Vancouverites it's a gentrified former industrial site you can walk to from Markus's shop). I've not been yet but it seems like...

    Just a note since this thread is still going on that I think ABom's post "retirement" videos are getting better again. He's doing more interesting repair projects and getting back to the nice balance...

    That's because they have actually banned multifamily housing in most of the city, so there is tremendous pressure on the industrial and commerical land to become apartments. In Vancouver for example,...

    Interestingly, McMaster Carr only has 5052 starting at .032" but they have 2024, 3003 and 6061 at .025. That doesn't mean you can't get 5052 in .025" but McMaster often has the stuff that's...

    How thick are the wafers? I see you can get Alumina down to .1mm. I'd be trying to convince the customer to go Macor so they could be made with regular drills, but it only goes to .5mm (from...
