    O.T. Emergency toe amputation.

    Hi Mark Rand: Yeah, I agree (LADA diabetic here but not much history yet...only a couple of years) Part of the problem is that if he's already having gangrenous ulcers, his circulatory system is already pretty beat up, and he has to nurse it along now, and get as much mileage as he still can out...

    O.T. Emergency toe amputation.

    Hi rjwalker1973: I assume your surgeon gave you the stern lecture about keeping weight off it and keeping it elevated if you want it to heal without further problems. I encourage you to take it VERY seriously. As you may know, the root problem you have is atherosclerotic end arteritis...this is...

    Manufacturing Dental Root Canal Files

    Good morning 1001_DH: These guys: https://rollomaticusa.com/ Their machines are probably the most widely used for grinding Hedstrom endodontic files which are among the most difficult cutting instruments to grind (very long, very skinny tapered helix, complex flute geometry etc etc). They are...

    How common is sharpening your own endmills ? Favorite grinder for that purpose ?

    Hi GregSY: Are you talking about corncob roughers? If so, they are unique in the sharpening world because you grind the face of each flute rather than the outside edges of each flute. So there are a couple of unique things: 1) If you have a variable flute cutter you cannot conveniently use an...

    Is this Adjustable Angle Plate ( Precise 10" x 15" SKU: 202-169 ID: 347297 ) worth it?

    Hi EPAIII: I'm assuming you're talking about manual mills here, (like a Bridgeport) and in this circumstance it depends, of course, on what you want to make. An example from my days as a mold maker before CNC was a common thing: Some features in some plastic parts are molded with slides, which...

    Is this Adjustable Angle Plate ( Precise 10" x 15" SKU: 202-169 ID: 347297 ) worth it?

    Hi Rough-cutter: Are you planning to do this kind of thing often, or is this a one-time job? If it is, then a skeleton frame with a sacrificial plate bolted on top of it is the easiest way forward. Basically you bolt sawcut aluminum wedges onto the mill table, surface them at the correct angle...

    Is this Adjustable Angle Plate ( Precise 10" x 15" SKU: 202-169 ID: 347297 ) worth it?

    Hi Mtndew: Naahh, I've worked with some truly gifted guys who were well worth listening to, collaborating with, and socializing with. The true dickwads were in the minority and they typically sorted themselves right out of a job fairly promptly. A few were naive about just how much practical...

    Is this Adjustable Angle Plate ( Precise 10" x 15" SKU: 202-169 ID: 347297 ) worth it?

    Yep, Houdini...your experience is just about the same as mine. I'm grateful for my sinker...there are places where it is the only realistic way to get what the engineer truly NEEDS. But like you, when I design a part for molding and design the mold, I will move heaven and earth to invoke the...

    Is this Adjustable Angle Plate ( Precise 10" x 15" SKU: 202-169 ID: 347297 ) worth it?

    Hi Rough Cutter: You wrote: "But we don't have one and these design engineers never seem to learn. They just want what they want." You do know, I'm sure, that if your friendly clueless engineer really REALLY wants to make these without fillets it IS possible. The magic tool is the ever so...

    Welding to a Coil Spring?

    Hi RonRock: If you just braze them on you will avoid the potential for cracking at the weld. Cheers Marcus www.implant-mechanix.com www.vancouverwireedm.com

    Banned on Youtube wannabe machining channels. TOR tip.

    Hi TeachMePlease: You wrote: "it's satisfying to watch someone else do it well, on big stuff that I'll likely never touch." I couldn't agree more! I have the greatest respect for those of you who do big stuff...I'd get impatient if I needed a crane to change the chuck on my lathe. Stuff where...

    Looking for someone who can burn an .008dia hole in a .025dia gage pin.

    Hi bob: A hole popper has some advantages but also some drawbacks: It has high pressure flushing...that is good. It relies on a ceramic guide bushing to keep the electrode running concentrically...that is normally good, but in this instance, it is bad. I say so, because you need a custom size of...

    Does myasthenia gravis mean the victim should be terminated?

    Hi plastikdreams: I respectfully have to disagree with you in this instance...let me explain why from my own perspective: This is HIS disease and his disability to learn to manage...he gains much more from taking ownership of all of all of it in his own way. I understand the desire to...

    Is Mastercam still the right CAM for us??

    Hi huleo: I confronted a similar scenario about a year ago...I was asked to recommend all purpose software for a client who was building up a machine shop of their own. I ended up accepting the limitations of Mastercam 2023 despite its shortcomings (yes there are many) and my reasons had nothing...

    Does myasthenia gravis mean the victim should be terminated?

    Hi again Cannonmn: I commend you for your compassion in even considering this, and trying to find a solution. The best plan IMO, is to have a frank discussion with him, acknowledging his growing disability (if not now then later). reassuring him that he is not abandoned and working TOGETHER to...

    Face Grinding Graphite

    Hi dweekley: If you are hoping to face grind something like this on a jig grinder, I expect you will always have difficulties holding your finish and I say so because of the mechanics of face grinding. The culprit as I see it, is that the contact time between any single abrasive grain in the...

    Does myasthenia gravis mean the victim should be terminated?

    Hi Cannonmn: Like Conrad Hoffman, your choice of title alarmed me too and put my back up a bit. I say this because I suffer from MS which is not identical but is similar enough, and the end game is about the same. At this point, I am mildly disabled, but I am far, far from useless, and I in no...

    ot, gluing dentures

    Hi againsurplusjohn: I just re-read your other post where you wrote: "I have since found out that she used super glue which worked but it then broke in two other places. not sure what's going on!" Almost certainly, she did not get the halves back together perfectly, and now the denture is...

    ot, gluing dentures

    Hi surplusjohn: Yeah dentures were traditionally made from heat and pressure cured poly methyl methacrylate (PMMA) (acrylic) However, in the last 10 years or so, increasingly dental labs are one-time injection molding them out of acetal copolymer. The material is called "Zirlux" ...it's tough...

    Bandsaw guide blocks from solid carbide endmills

    Hi Garwood: You wrote: "The method I like to use is installing the endmill in a toolholder then removing the flutes with a rapid impact with hold downs or vise jaws." Owww, you made my teeth hurt with that one! Here I was hoping for an elegant artistic solution and now my confidence and self...
