Grinding lathe chuck jaws. Part 2 Removing the birds mouth effect from inside and outside jaws.

- This video is about making an old worn lathe chuck usable. Grinding the chuck jaws parallel removing the birds mouth effect so the jaws have a stronger positive grip. I also skim the whole chuck body because it runs out of true to the axis of rotation when mounted on MY lathe. The chuck has a slim body and fits within the gap when holding large components this is why it was worth saving. This chuck may not be hi tech but it will be a very useful tool in the future and good enough for my type of work.
That was an interesting look at a process I haven't seen before. The handheld video looked just fine. Thanks for posting this.
Thanks for viewing and commenting still on editing early video footage stuff. The later filming I do is not as wobbly etc. Thanks Tony
Looks like new now it really came out excellent. Id be super proud of it. Id stamp a date on it somewhere so you know when you restored it.
Thanks for your comment Gary. I think I might just do that on this and future projects.
It will make an interesting reference date for any future owners. Thanks Tony
It is my belief that chuck housings become distorted because of the extreme forces exerted by clamping parts in them, sometimes for hours, or for me, sometimes days. I worked in a diesel engine machine shop, that was when I found out how flexible cast iron is, You can take a truck engine block, put an inside mic. inside of a cylinder, longways with the block, then with your hands, press the sides of the block and make the mic fall out. Nice job on the old chuck, It will work like new now, I probably have a couple that I need to do.
Thanks for the info. I know that cast iron machine tables can bow I have two of them. I thought the same with the clamping forces on the chuck over the years. Thanks for watching and commenting.
@@eyuptony I enjoyed the video, I always learn from others.
Great work sorting out the wonky chuck, you know some stuff Tony 👍👍👍
Thanks DJ for watching and commenting.
That came out great. The router did a good job. And you to of course. Using the sawblade is a brilliant idea.
Thanks Rustinox for viewing and commenting.
Tony that chuck came out great!
Thanks it will work a bit better now. Thanks again for viewing and commenting.
Hey Tony, pretty good start to the stickerboard. Nearly at 300 subs now - keep up the good work. Beautiful result with the chuck by the way!
Thanks Craig sticker board lol Thanks for watching and commenting
Nice looking chuck now thanks for the video
Thanks Joseph for viewing and commenting.
Tony, I just came over via Ade’s Workshop. I just subscribed also.
Thanks for subbing John.
Nicely done, that is a very handy sized chuck and it will be plenty accurate for a home shop environment especially since you trued it up on the lathe it will be used on. The T-slots make it even more useful.
Hi Everett. Yes it will be true to this lathe only. Thanks for watching and appreciate your comments.Tony
Great job . It came out really well . Cheers .
HI Max it should come in handy now and then with it having a thin body. Thanks for viewing and commenting.
That came out well, good job. Cheers
Hi Paul thanks for watching and commenting. Tony
great job man , Have you seen the doubleboost channel ? John has the same lathe .. ENJOYED !!
Thanks Shaun. Yes I like Johns channel. Glad you enjoyed. Much appreciated Tony.
very good work, you did not video true test it?
Hi GMI thank you for watching. I'm still not able as my machines are stored and waiting to be moved to my new workshop. Tony
You made that look like a brand new unit.
I have seen it suggested in the past that cast iron can warp over time, do you think that was the case with this chuck?
Hi Craig. Yes cast iron can warp I have two wood machines with tables that have a slight bow on them, as does my welding table. Tony
Cool. What's the grinder ade out of?
Hi its a wood router, the part one video shows why I used it. Thanks for watching. Tony
3:36 There's something very suspicious with this - as clearly the jaws are not worn where they hold the work. So where is the wear ? In the slots that hold the jaws in the chuck ? If anything, I don't think parallel is the ideal - more like over compensating - so that the first part of the jaws closes first. What's the cost of a set of new jaws ?
Yes the slots are worn that's why the jaws tilt to form the birds mouth. Its a really old chuck not worth fitting new jaws if you could get them.
@@eyuptony A lot of videos I see and lathes/machines in general, I don't see much in the way of lubricant on working surfaces - and I guess that goes for chucks too. Maybe many of us are a bit lax in putting lubricants where needed to reduce wear.
@@millomweb My machines are always well lubricated where they need to be.
@@eyuptony Good ;)
Good video, I've squared a few jaw's over the years, like the way you did yours, never thought of sprucing up the whole chuck like that and great idea as a datum for putting on mill. mind you I'm usually in a rush just to get work done. But it Looks great. And definitely will be very good for the home shop.
But I must say, I really don't like taking material off chuck bodies, special in a business sense, but on your own chuck in your own shed well it's up to you, but people do need remember chuck bodies are tested as manufactured, and like flywheels on engine's you take to much off it will exploded under higher speed and loads with a job in jaw's.
Sorry thought I better say the obvious. But it looks great and I like your video's , I think anyone that stands up and makes and share's videos are top People thanks.
Thanks for watching Cledwyn I understand completely about the commercial industrial aspects on safety. This is only for me to use now and then. If I was a professional in this trade I would have ditched this chuck bought a new one to save time and to guarantee accuracy. Tony
@@eyuptony great video's, very entertaining,👍
Nice job, what was the end result. What was the runout?
Hi David. I was packing up to move my workshop as I finished the chuck so I didn't get test it. Once I'm up and running again, it's been a slow transition moving.
I don't expect it to be A1 but as long as it holds the work square the chuck will do for first operations etc. Thanks for asking. Cheers Tony
very nice job! Looks brand new.. clever idea to hold the jaws tight. Thanks for sharing
