    Assuming these are 3/8" clearance holes and the screws thread in wherever they're going properly, I would so write up a process deviation, pay grade be damned. I do like your Dremel wrecker though....

    The OP sounds like an investment analyst, which is no bad thing. I certainly like talking to them in our industry because you end up learning things you didn't know. I would say that vertical...

    I didn't see if this has been touched on but I've never seen a proper back gauge on a finger brake. I was comparing notes with some university engineering shop colleagues here and since we are all...

    Good examples already but I'll add the cabinet drawers in my cabinets in the last post in this thread: Anyone ever use the Lista Knock Off's from Global Industrial? Look at the drawer parts in the...

    If everything is operating properly it should have around .002" to .003" of taper per side, so .006" total difference in diameter, smaller at the bottom. The taper is pretty constant with thickness,...

    Thanks Mtndew you saved me looking up the quote in my own records. As I later hazily remembered, we indeed bought a regular 2" 390 on a capto C4 mount with a 6" extension bar a few months ago. I...

    I just ran it through Omax Make and a 12" disk of 1/8" steel would take 1 minute 45 seconds at Cut Quality 2 at 45,000 psi, which is less than a lot of bigger shops machines would run. So you'd be...

    How much is the regular 390? I'd be inclined to believe that it's real but perhaps in a narrow application range. We're a prototype shop so don't push production, but every time we get super fancy...

    Have you got your electrical costed out? For that install we did it was around, in Canadian dollars, $10K for the window remove and replace, $10K for the rigging and $10K for the electrical. It's a...

    What's your actual floor space and installation pathway i.e. door widths and heights and floor capacity along the way to your lab? For 4 or 5 axis for small parts the VF-2 would be a really good...

    The original inch series of 80/20, the 1010, 1020, 2020 extrusions etc, have these extra grooves which are purportedly to help hold fasteners tight by providing more edges or something. All I know is...

    Sorry I wasn't very clear in my post. The 8020 is in a weldment but the panels, which fit in the 8020 slots with gaskets, were originally separate parts in a design table but are now part of the...

    We haven't talked about design tables yet, which is another useful tool, but in the right application. If you don't know, it's way of using a spreadsheet to create and manage configurations of a...

    You just changed my life. I had been looking for this but hadn't grasped you have to right click on the cut list item, not the body itself. This was five minutes work to add a Description and Length...

    More and more for me but particularly where the parts are intimately related to each other. In the long essay I wrote above, the reception screen frames and panels are weldments, that are one part...

    Solvent welding acrylic with methylene chloride works really well, with a couple of caveats. The first of course is that methylene chloride is very dangerous and you want to work with it under a...

    The downside of course is space. If you have the space, go for it. The TL-2 is not ridiculously long anyway like those 16' manual lathes on Craigstlist going for $2K because no home shop can house...

    Our local Metal Supermarkets only sells sheared material down to 22Ga which is around .03" or .75mm because their big hydraulic shears apparently can't reliably cut 24Ga (.024") properly. That might...

    I counted:

    5x surface grinders
    2x tap extractors
    2 press and 1 finger brake
    8-10 drill presses depending how you count the gang drills
    6x horizontal mills
    3-4 Bandsaws
    3x Moores, one grinder...

    Peugeot grinder mechanisms are fine, and I say that a cook and someone who has turned a pepper grinder, out of aluminum no less. You do have to adjust the tension correctly.
