    My Sheldon (1975 EM-70) has a split nut with the ability to adjust for backlash. Have you had yours apart to see if you have it too?

    No doubt you're most enthusiastic about your bigger, full systems but your 'Dust Deputy' mod for shop vacs is an exceptionally well done product. I think it really does what you claim and I haven't...

    Sounds like you're back in business! Getting 'warm' at that load is to be expected and that motor should have a 40C rise rating. Thanks for posting the results, it helps everyone for next time....

    I agree with Ed. That's always a cleaning issue. I use acetone too, but even with that you may have to swap or fold the towel, cloth etc and go over it twice or more to get a good cleaning. In my...

    How about ganging two available valves? Or, just using one of those hydraulic valves you've mentioned? You'd have to pull the spool and add a good lubricant but that should be relatively simple....

    Have you looked a Norgren products? They have 24V air valves in many configurations. You can start here: Directional Control Valves - IMI Precision Engineering

    The smaller the pipe, the more pronounced the 'curl' in the ribbon. If you are looking for generally flat ribbon use the largest diameter you can.

    With sch-40 pipe in that diameter it might not be...

    Simplest thing I can think of is 'museum putty' or 'mounting putty'. It holds surprisingly tight, doesn't soak in or stain and is not difficult to remove with a bit of gentle prying. Last I bought...

    Did you notice that the 'search entire site' is done by Google? It just automatically adds the practical machinist element to your search.

    Well, I just entered the same terms on the site search tab, 'entire site' and got 1700+ returns. It was automatically a google search and said so right next to the search box. When I entered it into...

    I think you'll be happy with that. I've heard only good about WEG and I suspect mine was just 'one of those things'. The 7.5 hp WEG on a Quincy at work runs often and 24/7 with no problems. Just for...

    If your machine is a desktop with expansion slots, and windows version is win-2000 or later, you can add usb capability with an expansion card. Then you can use an ordinary usb mouse or a wireless...

    Brazing and soldering would both be slower than an end-weld with TIG, and post op finishing is minimal with a properly done weld too. Soldering or brazing 304 requires flux, and therefore its removal...

    There's not an epoxy made that is as fast as TIG! Depending on your requirements, you don't need to do a fillet weld all the way around the shaft. One way is to drill through, then insert the rod not...

    The OP said he doesn't want to weld. May have a good reason.

    Munruh, I just looked more closely at your photo. Is that going to be used as a handle, as in torque applied to the joint? If so, I don't think any adhesive is going to work for very long, because as...

    OK, the stuff we use, recommended by LocTite, is EA E-20HP Hysol, part #29314.
    I'd not recommend using ordinary 'permanent' LocTite because in my experience it isn't very permanent on 304 to 304...

    We glue 304 daily. The joints are in the weather, subject to wide temperature swings and some relatively low-frequency vibration. I'll try to get the mfg and PN later at work. Still, 'permanent' and...

    This is what I was thinking. Few situations would require a 'barrel band' approach.

    Everyone has assumed that you want the lowest friction, but from your description it seems that while clamped you want things to stay in place. Since you will loosen the clamp to move the part it may...

    Honestly, those darn ribbons are what most of us want to avoid. I cut PVC with an ordinary triangular insert that has a mild non-serrated chip-breaker that doesn't break anything at all with PVC. The...

    You probably could, but some have a small vent hole to allow air to escape. That can be important because an air bubble around the pellet will prevent it from sensing heat properly. In addition,...
