If the source of spare stepper motors doesn’t work out (or even while you are waiting to find out), please post the specs of the motor, i.e. approximate size, step size, coil resistance and current rating (and inductance if known) as I have a much too large collection of old steppers, mostly of the correct vintage, and I might have something that would do.
thanks for your kind offer. Need to wait and see how the US offer pans out.
looks like my contact Dave in the US is coming good with his offer. Expect to have two steppers available for pickup in Ulladulla around the end of the month. Best part is no charge either for the motors, “free to a good home”, or the transport to Australia (Dave’s friends luggage).
If anyone is going to be in the Ulladulla area early November and is willing to pick up the motors could you please let me know via private message?
Dave in the US has come good and there are now two Emco steppers waiting for pickup in Ulladulla. If anyone plans on visiting the area in the next two weeks and is prepared to do a pickup could you please let me know via PM?
Current status on this is that the stepper motors are still in Ulladulla. Unfortunately Neville, the keeper of said motors, didn’t end up making a trip to Canberra this week.
@ian has indicated he may be in the area in a fortnight. Will keep you posted.
Thanks to @spanner888 organising a pickup the stepper motors arrived last Wednesday. I replaced the broken motor and am pleased to report that the lathe now has working X and Z axes.
Yeay! Made anything yet? Photos?
Not yet. Tool changer is still in the cupboard. It needs to be stripped, cleaned and lubricated before being reattached. Once that’s done the question of tooling needs to be addressed.
The automatic tool changer uses carbide inserts. Right now we have a right to left cut tool (facing) and a threading tool. The RL tool is a workhorse and has 1 unchipped end. Don’t imagine the threading tool will get a huge amount of use. It is also chipped on one end. A new LR tool is needed but may be expensive, Emco spares are a high end item and uncommon.
We may want to consider replacing the auto toolchanger with a quick change toolpost (Chinese). The upside would be cheaper, readily available parts. The downside would be manual toolchanges.
Other items on the to do list are
. Dust cover
. Display screen
Progress Report #?
with Ryan’s help connected up an old plasma TV and checked the video was working. Makes it SO much easier to enter CNC programs.
