Turret Lathe Mentor Needed (hoped For)

Any suggestions on Min/Max guidelines on gpm choosing a flood coolant pump for the Gisholt #5?
Looking at Greymills pumps. I've got an option on a nearly free, working, used one. But, the deal is only on if I can assure him it'll work for this application.
How do I know?
Nothing in the Gisholt manual (I've got) about flood coolant pumps.

General guidelines?
Suggestions?
Opinions?

Daryl,

The coolant pumps are not generally covered in the machine manuals back in times. I tried to get a good look at the one on my L & S, and all I can make out on it is the "Gusher" name. It's only about 1/7 HP, not much! Seem like the GPM is about 6 to 8. Maybe someone else can provide more information.

Any fluid pump that will move the coolant in a steady stream will work for a general coolant supply, if however you are using through spindle or through tool coolant you may need higher pressures to make it effective.

If you just want general flood with open lathe tools and drills on a small lathe any small submersible pump will do, your goal will be to flood coolant at the tool, not shoot the chips out of the machine, Little Giant makes excellent pumps for this purpose.
 
I'm attempting to plan out turning Van Norman 5V collets.
The thread is .775 x 18.
Any suggestions on how to best proceed?

In the 70's I ran a Jones and Lamson turret lathe. Not sure of the size designation but it had a 12" 3 jaw and could run collets too. My boss at the time had worked for an aerospace manufacturing company in the Los Angeles area running nothing but turret lathes. The first thing he taught me when setting up was to set all of the turret tool offsets the same. This minimized the amount of cranking to engage the tool. When making hundreds or thousands of parts a 1/2" of extra cranking added up to a lot of lost motion and wear and tear on the operator.

Hope this helps.

I'm going to wade back in a bit here too. We have the hardinge turret lathe (from early posts) and my Son and I still hoping to pull that thing out soon. I'll get the two books mentioned in the posts above. Fun machines to learn upon it seems. How I wish I could retire and play all day. Thanks to all the guy's who jumped in here. It's a really productive thread!
 
I've got an old Bardons and Oliver that appears to be a Warner & Swasey clone of sorts. Here's a thread for mine. http://www.hobby-machinist.com/threads/bardons-oliver-5.16120/

Anyway, during my search for information I found a PDF version of the book entitled
"How to get the most out of your turret lathe : A guide to modern practice in work planning, tooling, and production."
published by Warner & Swasey in 1963.

If anyone want's a copy let me know and I'll try to figure out a way to share it. It's a 100m file. Perhaps I can get it to someone who can post it up in the downloads section or someone can help me figure it out and I can do it myself. Not sure if there's a copyright issue or not but the book is 50+ years old.
 
I ran 2 different turret lathes today, a small Hardinge and a large Warner & Swasey #5.
Spotted, tap drilled and tapped 55 brass parts 8-32 X 1/4" deep , it took less then 1 hour including setup, however I did bore a 5C emergency collet the day before on a CNC chucker lathe, the threading would have taken me 3 times as long in the chucker, the turret lathes are fast.

Then drilled 1 1/8" through 2 3/8" Dia. 1018 CRS blanks 1 1/2" long on the W&S which has a power feed turret, no spot drill or pilot drill, straight through with a 1 1/8" taper shank drill 84 parts in 3 1/2 hours, a turret lathe can not be beat for this type of work. The actual machining time was less the 1 minute each, 128 RPM X .018 Inches Per Revolution is 2.3" per minute feedrate. Chucking and unchucking the parts in the 20" 3 jaw scroll chuck took longer.

This machine has a hydraulic collet chuck system with collets up to 4" Dia. (it is 5" through the spindle) if I could even find the parts and a collet of the correct size it would likely require 8 hours to change the chucks for a 3 hour job. Warner & Swasey used "push collets" that have the taper on the front which are pushed in the direction of the turret rather then pulled into the spindle.

All in all very useful machines for this type of work, setup is everything yet is not worth doing if only making a handful of parts.

A W&S #5 is not a small machine
