    Joined Jan 28, Messages 2, I used hack saw to rough out the machie and then set it up in my milling attachment to finish the nut. The first one I used the saw method but finished slot file as I did not have the milling attachment at that time. For my new set of Phase II, I am making a new top slide for the compound nuts will just drill and tap a hole for the tool post bolt.

    I hope to finish it this week. PurpLev Active User Registered. Joined Feb 22, Messages I measured t slot dimensions with a caliper, cut out a rough block of steel, and using a milling machine squared and dimensioned the part to size, and milled out the T rabbets: Sorry I don't have any in-process photos, but these were basic milling steps - squaring and dimensioning a part, and milling a step at a certain depth from a dialed nuys edge. Joined Nov 5, Messages Well, I didn't know enough to do it properly.

    All I had was machine 9" lathe First I measured the compound milling determine the dimensions, and marked the areas to be removed on the supplied t-nut blank. I chucked that blank endwise into the 4-jaw and faced it down to the correct width. I installed the QCTP stud in the blank, then chucked it in the slot. I faced of machine down to the correct thickness.

    Length was OK. Now Slpt had a blank that was correct thickness, length, and width, just needed the steps milled. I made a round t-nut in the lathe nyts fit my topslide. This let me temporarily mount my new QC post. I probably could have used this indefinitely, but it does not spread the load across the casting as it should. Then mounted the blank that came milling the QCTP into one of the toolholders, using it as a milling vise.

    I adjusted the height to get nuts cutter where it needed to be, then milled off the shoulders to the correct dimensions. Replaced the round t-nut with the newer version.

    This works OK because the tolerances are very loose. Joined Jun 17, Messages 2, Benji Active Member Registered. Joined Kachine 14, Messages You really do not need anything more than a lathe. First rough cut to size. I used a horizontal band saw but a hack saw and a lot of sweat would work. Make the width 0. Now break the corners. Remove any buildup.

    Next I screwed the blank onto the milling it came with and chucked it up in a slot jaw chuck. I turned a stub the nuts of the compound slot less 0. Doing it this way insures the boss is concentric with the screw shaft and the top flat is at right angle to the Boss.

    Again allow 0. Break the top corners to allow clearence from and radius in the corners of the compound tee slot. machine

    This was for an Atlas 10" lathe and here is how it fits. ScrapMetal Amchine User Registered. Joined Apr 6, Messages 2, Trimming to width Using a block to space it in the chuck and a combination of two jaws and live center to hold it in position. Almost finished. Fitting it to the compound. Thats another way to do it. You guys making stuff on your lathes that I never thought possible. Joined Jun 17, Messages 1, I guess I have to put in a little tool gloat here.

    I never expected to have a mill that could do this.

    The hubs on the cutters are flush with the edges of the teeth, so the thickness of the shims equals the space between the cutters. With the right setup, one pass completes the profile. Feel the power! Show off!! Really makes me want to put a little more effort in to get my horizontal motor in to play on the W-I. Joined Jan 23, Messages 1, Joined Jul 26, Messages 4, The important thing is to make sure that the sides of the inverted "T" are parallel,if you file it out.

    If not,your lathe compound could be broken by unequal forces,too few contact points,etc,pulling up on the compound when it is under tension during a cut. If you can't make the T nut any other way,just turning the round riser in the lathe is perfectly O. At least,if you face this part in your lathe,leaving slot tall neck, you can be sure it is parallel,and will touch the T machine in the compound everywhere properly. If you must make it by hand,use blue paste to check that it fits everywhere under the T slot in the milling.

    I agree with you Frank. The method you suggest is pretty much the slot I prefer using. Unfortunately milling one doesn't have a mill or shaper available to them they need to have an alternate way to get it done. That's where the "lathe method" comes in to play.

    It's also my "gut instinct" that the "T" with the rounded portion, as produced by the lathe, would not be as strong or as machine as a conventionally shaped "T" but it would take some good structural nuts to determine if those differences are great enough to have any affect on the system.

    I would like to see such analysis if anyone was looking for something to do Thanks, -Ron. Joined Sep 24, Messages Froneck said:.

    Then Nuts drill and tap the threads for the stud. Screw in the stud and use red locktite. I revese the "T" with the stud installed and drill and tap a dutchman Frank. Tony Wells Platinum Registered.

    Description These T-slot nuts fit a (12 mm) 7/16" T-slot and are threaded 3/ The nuts are the correct size for the Mini Mill. The 12mm nuts are heat treated and have a black oxide finish. Nov 18,  · You buy a new QCTP and it comes with an oversize "T" nut that you have to mill to size. How do you do it? (Photos if possible). How do you measure the correct dimensions of the T-slots, set up the job on the milling machine or other machine that you use, and remove the excess material. t slot nuts at Cromwell.

    Why not mill out the slots? I am pretty sure I would do that rather than chase around making special tee-nuts machine and every time I needed a few more.

    Monster T slot for such a baby mill. Commercial T nuts are way overkill. Grab a short foot of extruded alloy bar and chomp out a stick to "rattling good fit" in the slot size.

    Tap to any convnient size making sure the bottom thread is incomplete so you can't drive the stud or bolt right through. I find a flat ended second cut tap leaves a sufficiently incomplete thread if taken down to no more than flush with the bottom face.

    Just be careful to get the slot faces of the T cross bar on the same level so the nut comes up square in the slot and ensure the tapped hole is exactly perpendicular to them.

    Everything else is in the wind so small variations and slight out of squareness matter not nhts jot. Best if things are close tho'. Offended aesthetic senses tend to adversely impact the quality of work done. I've always preferred studs to bolts in Tee nuts. If rolling your own its easy enough to make permanent Tee nut and stud assemblies, especially as you only have one T slot to worry about. There is an argument for using stand-offs, internally threaded at both ends screwed onto short studs in the Tee nuts for all except the shortest stud 'n nut combinations.

    Stiffer than a simple stud, so adequate clamping is often possible via simple bar on top, and it holds the assembly in place by nipping down onto the top of the table when screwed on. With small work nipping the T nut and stud in place slit be a great help in getting stuff tied down.

    Small items tend be light and easily moved.

    Whoops, we couldn't find that.

    nuts Often the feature you are clamping on is quite small too so it really helps if at least one part of millibg clamping arrangment is tied down before you start. With only one Tee slot you may well find X, Y and V shaped clamps milling. Wedge step blocks machine get in the way on these small machines.

    Much better off with stacking spacers and a short jack screw on the clamp slot. Just don't run the end of the jack screw direct on the table.

    Personally I'd pretty much forget the whole T slot thing and fit a grid of holes plate on top of the table. Slot aluminium breaddboards from Thor Labs do just fine.

    Travers Tool has them. Originally Nuts by HuFlungDung. This means they would be undersize by 0. Is this too much? Milling Sami liked this post. Just a piece of flat stock to fit the bottom of the T slot. When you get a bunch of chips down in there, you still want to be able to slide machine out without undue force, rather just a bit of rattling and wiggling and they come free and move.

For pity sake, you are not the first one who needs an odd size T-slot nut. They make them in many, many sizes. I purchased a "standard" clamp set for my mill and the nuts did not fit the table.

    So I bought new nuts.

    No problem and no grinding. Here are eight from MSC that appear to fit your slots. If you do not like any of these, just back up in the search and use your own numbers.
