Machined pengun - Dimply

[jackssmirkingrevenge]

You have now all the basics to meet French girls... and succeed!

To be honest, I've never had much interest in continental girls, top of the charts are all from further East. Better looking and better attitude

[LeMaudit]

Okay... I should have say French talking girls...
Try Quebec girls Quebecois are like French, but on a good mood.

But... my wife if from Slavic origin... so... I'm not qualified to give advices

LOLOLOLOL!

There you go, we're of the same mind anyway, this is drifting ever so slightly off topic... when can we expect the final cuts and dimples?

[LeMaudit]

I will do my best to do the flats during the week. Half of my customers are on holiday, so the heat is down

About how to solve your compulsive gluing problem, here's a big hint:

Index Block

Why not tell him to make some disposable ones with a piece of hex stock might as well foster additional learning when it's an option?

[LeMaudit]

Why not tell him to make some disposable ones

all right ... another big hint...



[edit} and the plan is octagonal

[inonickname]

Oh, I thought you wanted him to use indexing blocks instead of the rotary table. Makes sense now.

[LeMaudit]

Okay, enough clues. Or we'll lost JSR in a metal chip cutting mayhem

If you take the brass holder and make an indexer out of it on the rotary table, by cutting 8 flats on the longer cylinder part, then you can later use it as a simple indexer on the vise, holding the nose and with the barrel going through.

After that it's only a matter of setting the end mill to the proper height and cutting a flat, rotating to the next flat on the vise, cutting again, etc...


JSR: Do that only when you are sure you don't need to grip the tube in the chuck again, as will be quite difficult to grip it with 8 flats on 3 jaws chuck

[edit]] I will keep on the nose a full diameter just before the flat or there will not be enough contact left on the joint, and I will use a rounded end mill... just for fun

So maudit, when does the cartridge carnival start? I would say start with hybrid and work your way down. Make the easiest last.

[jackssmirkingrevenge]

What I was thinking was threaded tube in the rotary table, though thinking about it the mill probably won't go high enough to reach the nose with the added lift of rotary table + chuck.

See, if I hadn't hidden my credit card I would have spent another $156!

JSR,
I'm glad you didn't spend the money. A 4 jaw independent chuck has more utility than a 4 jaw self-centering chuck.

[jackssmirkingrevenge]

Noted:

4-Jaw independent jaw chucks have four advantages over a 3-Jaw Chuck.

One, they can be used to hold irregular shaped parts.

Two, with the use of a dial indicator, they can be used to center parts with a great deal of accuracy.

Three, 4-Jaw Chucks can be used to deliberately hold a part off center;

Four, they can clamp stock in a tighter grip. This is a valuable asset when machining cams, crankshafts and other similar parts.

$28 cheaper too

... but yes, as posted elsewhere, no more buying tools for the time being.

Very true! I just bought one... just waiting for an eccentric turning project

JSR: Remember that you can also mill with the head horizontally. To mill a flat for example, you could do it moving horizontally the tip of a end mill... or it's side up and down. And your column have a lot more possible rotations than the one I am using in the video.

Aren't they all

Yep, still have to get my head around all the possible configurations and axes, which is important with my tiny cross slide... though really in this case, a bit of gentle heating and removing the nose plug from the barrel really is much, much simpler!

[LeMaudit]

Step 10: The flats are cut for the nose and the valve plug.

I changed a little the original plan:
The nose's flat leave a full aluminum diameter for sealing. I was afraid there was not enough material left by cutting as in the 3D
Also, the plug's flats are a little deeper, to accommodate a standard 1/2 wrench

Now it's only a matter of dimples....
