I inquired about parts from Royal several years ago, they had some parts but discontinued sales of the complete closer.

She says thanks for that, and its about time!

Hi Thanks!

That is partially it, there was survival of the fittest, no union to save your lazy ass, you work and figure things out

My grandfather was a WW1 Navy machinist and my dad was a WW2 Army Air Corps Line Chief, sort of a super mechanic, I just grew up with it.

@@deedeeindustrialsuperprecision Three of my four sons were in the Navy, one still is, a combat diver. I thank your family for their service.

I would like to do that I am enough at ease after 500 videos to meet any challenge. I just don't know how to do it yet, all I have is a low powered lap top and a go pro9

Glad to hear it! I find bits and pieces I can use too poking around, thanks!

The Timken bearing pulls the draw bar to center when tightening and makes releasing the collet easier but takes up more room than just a flat thrust bearing. Thanks!

You are welcome! Royal quietly dropped the handwheel closer some years ago.

@@deedeeindustrialsuperprecision probably lack of sales????anyway, Lyle 'Mr Pete' now has one for his lathe.....cheers...Paul

I have heard stories of little draw bars flying around in the watch trade days

you are sure welcome thanks!

Thanks!

Next video at the end shows two versions, thanks

Yes, any forces at all show up working in tenths. The adjust true chucks should be more carefully by not having tension on the side adjusting screws when the front screws set. The best conventional chucking is with a small as possible 4 jaw chuck, and even there the chuck jaws need even tension not to distort the chuck body, the ultimate is a shrink chuck where the workpiece is simply held using a steel disk with a slightly under size hole, that may be needed to avoid stress risers from chuck jaws on some materials. Thanks!

@@deedeeindustrialsuperprecision great info Sir....cheers, Paul

It is rapidly changing here, you my have seen old Robert in my video at the recovery yard, that is how long left on the clock for that scrap pile. I have got all I can take with me, I am getting out of here.

The Boeing company switched from Erickson double angle collets to the ER system in the 1980s because of better overall performance. I used Erickson from the 1980s because Boeing sold out so cheap. I bought my first ER 40 set for the horizontal mill and a holder for my lathe and drill and it is working really good. The only small problem is a part rotates when tightening the collet, the 5c stays fixed from its locating slot making it better on the cutter grinder work head for easier positioning of a tool. I have read that the ER are the most accurate available when they cost $171 each!

@@deedeeindustrialsuperprecision Thank you Donnie for your insight. I have an all Hardinge 5C set from 1/16 to 1" and a bunch of larger pot chucks and step collets. I have a Tsugami chucker, which is a copy of a Hardinge HC. I also have an HLV-H. I started with a cheaper ER40 set for my SIP MP5 jig borer, and I am going to fit a face plate on my B&S #13 grinder with an ER40 adapter as well. It is good to know the ER system is a good collet system. THanks. ---Doozer

Great discussion on 5c issues, I have the Monarch nose 5c chuck for my 10ee, but never built the drawbar (on the list), but do have the handwheel chuck along with a collet chuck, I have a lever closer for my Clausing 6313….never thought of the possibility of what you discussed…thanks for sharing

You can get behind a workpiece easier, polish and have your hands close better with collet chucks, I mostly found a 4 jaw is hard to beat. I will do a demo with scroll chuck and show what happens when they are sped up to top speeds, thanks!

Most manufacturers will have a line of high precision collets I have not had to purchase 5c collets in a very long time. I saw a price of $171 for a single precision ER 40 collet recently.

Dont you know it does not need it, do you ever read instructions?

@@deedeeindustrialsuperprecision I was just saying when round stock runs down on the bed ways its self some thing is not level. Was not being a butt. I love your videos also.
