If it helps, I have replaced the grease in my chucks with an oil. You really don't want something that's going to collect chips and hold it in to where they can get grown up into the very precise scroll. At least with the oil you have a chance that the chips won't collect as easily.
Great work, maybe 4” or 5” would have been a better match? The spigot should be tight in the back of the chuck. Don’t underestimate the ability of inaccurately drilled backing plate holes to make a chuck run out.
Good point, I think I'll drill the holes out larger, and see if I can tap the chuck into better concentricity (if, that is, the slightly bad holes aren't pulling the chuck off the register.)
I know how you feel about aircraft flying over, less than half a mile away we have a lake guy insists on landing on (even though he's already been fined several times) I think he may have changed out twin engine plane for something with shorter take off requirements as it has been a lot quieter last 6 mo ths or so (kinda hating on rich show off's) Did you get aluminium cutting inserts? (I saw HSS around 9 mins) Seems to be cutting much nicer Oh, found a book I bought in 1982, Book 6 of the Gingery Series (Dividing head and deluxe accessories) It includes instructions for making 4 jaw chuck among other things, I had forgotten how interesting his books are. I had plans back then, now, getting out of bed is a feat in itself 😁
If you get your new 3 jaw nice and concentric just once, consider drilling through the plate and into the chuck and install locating pins. Then would it be concentric forever?
Love it! So much fun!
You're slowly turning into a machinist there Mr Allen 😂😂 Using fancy words like maintaining concentricity. Nice chuck addition to the lathe as well.
Watch enough videos on youtube, and I guess some things sink in via osmosis ;)
As a former foundryman watching you do a loose pattern mold satisfies me for some reason.
Thanks, I'm really loving how easy it is to go from need a part, have a part.
You make it look so easy to make everything
@@Davidcarroll38 video editing covers up a lot of tedium, that and practice 😀
0:34 because they have no muffler

Point... at the time of filming, I just really did not want to deal with getting the grease out, and then disposing of used grease.

New insert holding shanks :)

Is this still zamak (or equivalent) you are casting?
Yes, still zamak
