I don't own a lathe, but it would be nice to have one I just don't have the space. I totally agree that dead center trick gets the ribbon. That was impressive enough that was going to be my comment and someone beat me to it. ........by a year. 😁 I also liked using that angle metal in the vise for a second bend. No lathe, but I have a vice. 😁 I just recently joined your channel and even though I don't have the machining tools that you do the procedures you show the imagery in your videos and your precise descriptions of your procedures is as good as it gets. Everything makes perfect sense and the added humor is the kicker. This is great stuff that you're showing. How about a video on improvements to a drill press table to improve accuracy or repeatability.

Another tip for the four jaw that I believe I learned from Tom at 'Tom's Techniques' is to clone your four jaw chuck key and use both keys simultaneously on opposite jaws. This really facilitates matters when truing work.

@drd1924 Жыл бұрын

I was going to suggest the same thing, I use a short small chuck key for the rear and turn both front and back at the same time for large adjustments and getting close. Then fine tune with the main chuck key one at a time. By this method you can often dial in to +/- 0.0001" TIR within 2 minutes from chucking part up... to dialied in. I used to hate dialing in a 4 jaw, but now...I never even use the 3 jaw lol since it would take more time to swap out the jaws than to just dial in. But this is a great video still, she definitely knows her stuff.

For the copper soft jaws i use a short offcut of copper tube/pipe, set the jaw point with a round bar held firmly in the chuck. Once tight squash the sides with grips, you then have to mark and cut the tabs similarly to the way you did but leave the rest closed as it helps stop the softjaws opening up once they have been used a few times. They end up the same as yours but closed at the back part.

@etprecisionmachine2379 4 жыл бұрын

A tip from a 45 year experience machinist: use a wiggler instead of a dead center. Wigglers are spring loaded so the tailstock won't need backing off. Put the indicator tip as close as possible to the work. The farther away the less deflection of the indicator. If you wanna really hold tenths then having the indicator tip 1/2 inch away from the work will not give accurate results. Furthermore, since one end of the wiggler is held in the chuck it won't fall on the cross slide. All of my 3 jaw chucks are adjustable. If bought that way they are more money than hobbiest folks want to pay. I have modified several of my chucks to make them adjustable. Small chucks can be challenging but I have done 4 inch chucks that work very well. Please let me know if you would like to see how I have done this. I can take some pics. And who doesn't like pictures of metalwork? Eric

Alternative: buy a few feet of annealed bare copper wire from the electrical dept of your fav big box store of a size that nestles in the jaw serration. Measure the diameter of your work and cut off a length that will wrap most of the way around. 3 times the diameter is close enough. Make a ring of the wire and slip it over the diameter to be chucked. After a dozen jobs you accumulate enough rings so the need for new ones drops to replacement level. The beauty of the narrow rings is they allow you to bump the far end of the work so you can dial in the full length very presicely for center driling. The ugly part is if the chucked surface is too smooth the work can slip axially under heavy cuts or drill feeds. The same is true of the design Quinn demonstrated. Axial slip is something to keep in mind unlees the work is blocked or solidly shouldered against movement. One thing, be sure the copper ring lies in the plane of rotation, preferably in a jaw serration. If it's skewed the part will tend to nutate (wobble so the part axis follows a cone.) If your four jaw lathe chuck jaws are smooth ie, have no annular serrations, you might consider grinding in at least one shallow groove. Do this in the lathe with the jaws locked on a short slug gripped at the heel. A Dremel or die grinder will do the job. Use a mointed point grinding wheel B-70 if 1/8 shank or A-36 if 1/4 shank. Dress the included angle to 90 degrees symmetrically on the radial plane. Two sets of jaws are handy: one ser smooth, one set serrated

@Gottenhimfella 4 жыл бұрын

I like the notion of being able to bump the axis true for long (eg shaft) work. I suppose this could also be done with soft steel wire, which would permit of gripping a bit tighter? Hardened C clips from round wire were sometimes used for gudgeon (wrist) pin retention (and can be made by starting to make a spring but changing your mind and cutting it into rings) but I guess these would mark the work, and perhaps not even conform well enough to develop a secure grip?

Use the live center to press the part up against the jaws using your center punched hole. Lightly snug down your 4 jaws and you have it dialed in pretty close. You can indicate with the dead center after if you need the accuracy. I used that trick to rough in a 4 jaws on existing bores/holes or when I had a center hole already in the part all the time. Usually gets you within a few thou depending on how close your tail stock is and saves time.

@peterfitzpatrick7032 4 жыл бұрын

Hey Quinn !! Regarding the punch hole alignment.... I prefer to use the machinists button method as its more accurate , as the hole can drift slightly during punching... So.... u drill & tap a suitable thread & lightly fix a button (ground & bored bush) to the part with a screw & washer. Then you measure from the part edges to the bush , & allowing for the button diameter, tap the button until its dimensionally where you want it. Tighten the button retaining screw & put it in the 4 jaw & centre the button, then remove the button & bore the hole. Sounds long-winded but once you've done it a couple of times it becomes second nature & is great for making accurately spaced multiple holes with a button for each coordinate. Works great for boring on the mill too !! 😎👍☘🍺
