Couldnt you do the morse tapers as standard,even if you didnt have a long compound travel,or was there a medical reason to install the power travel.

You won't do an accurate one by hand... Well I cannot...You are pushing poo uphill doing it on a lathe to start with (that is why every commercial one is ground), so why not reduce the variables to a minimum that all serve to create a poor quality taper..

The pewer feed unit has not been modified in any way, so I can easily take it off the lathe and stick it in the mill should the need arise...

A thread on the original idea here

angle cuts on manual lathe - Practical Machinist - Largest Manufacturing Technology Forum on the Web

I never had any that I have done not work as intended,most I cant do with the limited travel of my compound in one go.
Have you considered trying to synchronise your cross and compound to cut tapers.

hi RC ..talking of morse tapers .this tip might aid you . At the TAFE last year I learnt a clever method of turning a accurate morse taper ....

1. You mount a good accurate commercial morse taper in your chuck .

2. set up your compound as per normal for doing a taper

3. this is the clever bit, you use a feeler gauge and as you run the cutting edge of the tool up and down the good morse taper , you adjust the angle of the compound to achieve a level clearance all along the length of the piece in the chuck . After that is done, remove the good morse taper and install your blank in the chuck . You have a perfect angle to cut it ..MIKE

Hi Morrisman, there are a lot of ways to set the top slide, some better then others... I might discuss some of them in the taper turning thread.

It is clutch protected by the way I installed it, if it hits the end of the travel not much happens other then the unit keeps running but the feed screw does not.. There is no direct join between the unit and the feed screw other then by friction, which is adjustable..

I have been running the power feed on my turret mill for six years like that without any incident, in any case it is a small slide, not a z axis on a milling machine..



The top slide has 150mm of travel, therefore it will allow me to turn long tapers like morse tapers... I priced a taper turning attachment for this lathe....$2000.

Hi RC,
I didn't realise it was yours, I see what you mean about the clutch type set up on it, good thinking.

Darwin trying his best !

shame he didn't have his head under the chuck, eliminate that gene pool from the equasion.

Sadly, their numbers are increasing.

I have had the same observation.

He needs to try harder because he will breed.

These just popped up on PM. Micro-videos of steel and cast iron being cut.
