I have a high dollar Pratt n Bernerd 3 jaw that is vey accurate and repeats nicely. I don’t have to use the four very often if at all. But this video is well done and it’s nice to hear a fellow machinist that knows what he’s talking about and knows how to communicate.. rare these days.

nice the dial indicator is a must for hand milling machines as a point of reference and to gage any play in the material or equipment... i think it is an cool simple measuring device the makes you have really perfect measurements with out even really measuring

curious for chucks of different sizes do they all usually have the same jaws that you screw down into the chuck or is there different jaws you can buy. Not sure if different type of jaws for chucks are required to hold different things or is it usually one jaw type fits all for a specific chuck (lathe chuck that is )
@machiningmoments8 жыл бұрын
+sam111880 Very basically Sam, there are two types...three jaw (all working together) and four jaw (all working separately). There are soft jaws also (you form) typically found on CNC lathes. Having said all that there will be some other setup but these are the most common in my experience.

There's also the possibility that the 'straight' bar stock isn't as straight as it's supposed to be. If the length hasn't been stored correctly there's always a chance that it has 'settled' and bent. As much as possible I keep my small stock of bar in the house and stored on end or flat on the floor (depending on length) to reduce warping. I do this for most of my steel stock, round square, angle, etc, to keep the _rust monster_ away! The rest is -scrap- ... I mean projects yet to be started!

Thanks for the videos. Say I wanted to face a part, then center drill it in preparation for live center tail support. Should this operation be done with minimal stick out, or should you face/center drill close to the chuck, then pull the work out to the desired length of stick out for turning (with tail support) and then re-dial in the 4 jaw chuck? Basically looking to see if it is necessary to dial in the 4 jaw chuck twice during that sort of operation.
@machiningmoments7 ай бұрын
The rule of thumb is no more than 3 times the diameter sticking out of the chuck unsupported.
@mrmy21097 ай бұрын
Right right. So generally you would dial in your piece. Face, center drill. Pull work piece out to desired stick out. Re-dial in the 4 jaw. Then support with the tail stock. Right?@@machiningmoments

And if that bar was really 3/8" or less in diameter, would you be tapping on it ? Is there an alternative way to aleviate the wobbling ? tnx.
@machiningmoments4 жыл бұрын
It would be difficult to do in a 4 jaw. If the chuck had accurate jaws that would help. Also I would not hang 3/8" or less diameter out very far from the chuck.
@cosimomarotta95529 жыл бұрын
Thank you for sharing. It's the same way I use to. But my 4 jaw chuck has worse quality than yours so sometimes it's difficult to feel the just tight on the wrench to reach a 0,01/0,03 mm runout. Anyway to be in that range is enough for most jobs.

Help, I’m new to lathes, I have a 4 jaw chuck and spend a lot of time adjusting and if I need to turn the stock around I cannot seam to get it to cut even on the other side. Should I just use a self centering chuck or keep at working out the adjustable chuck? Thanks for the video.
@machiningmoments3 жыл бұрын
If you are new to lathes you will likely find a 4 jaw chuck challenging. A 3 jaw is a lot easier but if you persevere the 4 jaw is more versatile. Are you using a dial indicator? You will need one with a 4 jaw.

It definitely takes more time to setup. If you ever worry that the work may come out of the 3-jaw chuck, this is the go to chuck.

You tightened the jaws up too early. Don’t get them so tight to start with. I presume you were going to centre the end? As this was a long piece to turn unsupported. Taking into account this video was to show how to clock - up in a 4 jaw you never actually did that. Your chuck was naturally holding the work at an angle so it is out. Only packing shins will let you hold it tight and parallel so you can centre the end and support it in a revolving centre. Was a bit misleading to anyone starting out.
