    New trav-a-dials

    That seems to be an odd business decision Dave. I wish them luck, but given the availability of some fairly cheap yet still quite accurate off shore dro's today against what the original Trav-a-Dials cost, it might be tough. There are some situations where the available space or maybe...

    Toyo ml-1

    Given the lack of responses there now a fairly rare lathe. And I don't think all that many were sold even when they were still available. I've only seen a single new one at a tool dealers well over 20 years ago. But I look at making any improvements or modifications from the perspective of what...

    Converting Imperial and Metric threads to U.S. Threads

    Having an actual conversion chart would be the quickest method for metric - imperial or the reverse. But it's easy enough if you've got a tap drill chart. Just find the tap drill size in lets say metric, convert that to it's imperial decimal equivalent, and then find the closest recommended tap...

    Versa mill, is modernisation it a Sacrilege

    I'm unsure of what your asking about. What type / brand of mill and what taper does your mill already have?

    Vevor 7" tilting milling vice, mine landed.

    While I haven't bought one of the tilting tables yet. If the radii of both the upper and lower halves are that poorly fitting, then your preset datum point on the work piece to either one or both milling table travels is without question going to shift around. Depending on what you might be...

    Vevor 7" tilting milling vice, mine landed.

    If it were me and I was wondering about the fit between those male & female radii, I think marking one of either with even a sharpie as a fill in for engineers blue would work well enough to give you some indication for the fit between the two surfaces. I don't fully agree with Paul's video...

    Quieting a Noisey Bench Top Lathe. How ??

    No real need to start a new thread. I'll have to check my bearing OD's and ID's and then double check what the dimensions Weiss uses on there MT 5 spindle are. I'd maybe wrongly assumed Weiss used a different head stock casting for the increased spindle size. That may not be true if they did in...

    Quieting a Noisey Bench Top Lathe. How ??

    Mine is the basic 280 VF, but bought before they came out with the MT 5 large bore version. So it only has the MT 4 spindle taper and just over 1" / 25.4 mm through bore.

    Quieting a Noisey Bench Top Lathe. How ??

    Thanks for the additional information Neils. I was wondering if you'd machined your own spindle from scratch. And then how you might have rough machined, heat treated and then precision ground that spindle and the internal Morse Taper. Using an off the shelf spindle from a larger lathe was in my...

    Quieting a Noisey Bench Top Lathe. How ??

    Very interesting a much larger spindle of that size can be fitted Neils. You really should do a bit more in depth thread about how it was done here. I'm extremely impressed.

    6x26 Milling machine speed chart

    Here's the Grizzly Tools manual for it. https://cdn0.grizzly.com/manuals/g0729_m.pdf Page 27 should have what your looking for. But those speeds are at best only approximate. Given today's availability of rather cheap digital rpm displays, adding one might be more helpful. Even though I did...

    Nasty collets

    Collets are supposed to be properly hardened and then tempered back to a spring condition. That's due to how there designed to open and close while staying out of the metals permanent deformation range. There's a few warnings online about not trying to fully close any ER collet without the...

    thread measurements 13/4X8 T.P.I.

    What your doing is basically no different than making a back plate for any lathes threaded spindle. In general, most would recommend starting out by machining your own thread gauge that matches the wire measurement as closely as possible over both the dividing heads spindle threads and your...

    Mini Lathe Issues and Concept Execution

    While it would be difficult, very long lead pitches are completely doable on a lathe. Maybe not easily or possible with one that has a gear box, but with a plain change gear lathe it's certainly within what could be done. You'd have to add a whole lot more gearing than any lathe usually comes...

    Nasty collets

    I would have instantly returned those back to whoever I bought them from. They keep manufacturing and selling garbage like this because people keep buying it. But If I ever had to deal with something like those internal burrs, any steel scale and especially what I'm paying for mine sure wouldn't...

    Question about putting VFD on a step pulley mill.

    What pulley position to choose? That's literally impossible to properly give any accurate answer for since it depends on just what your doing. I look at the material I need to machine, and with a mill, then the maximum and minimum cutting tool diameters I'm going to be using as the first two...

    Questions regarding drilling small holes, and runout.

    While I do have a Haimer 3D edge finder, I still keep a couple packages of Zig Zag brand cigarette rolling papers in the same tool drawer as the rest of my more conventional edge finding tools. For some work, the old school machinist trick of using a cigarette rolling paper should get you under...

    Questions regarding drilling small holes, and runout.

    Before I learned the hard way what I finally understand now. Drilling holes or even using a drill press has a few more complexity's than some think or that seem to be almost never brought up on forums like these. Since it is so seldom mentioned, my assumption is that most with these lighter...

    Questions regarding drilling small holes, and runout.

    If those collets weren't even close to matching what's in writing for there run out specifications Baron, then they should have been immediately returned to the vendor. I don't try to re-machine, repair or modify what the manufacturer should have already been producing if that's what there...

    Questions regarding drilling small holes, and runout.

    Whatever videos you watched that show marking and then FILING collets due to excessive run out are being produced by literal know nothing morons Gavin. Well made collets get internally and externally ground to a few thousandths of a mm or a few 10ths of an inch after heat treatment, or even...
