Here is a good looking and reasonably easy to understand source
of DIGITAL HOBBYIST information....
I have no association with the author -- Just stumbled upon it
and I have not seen a similar reference to THIS

Your mileage may vary.....
Good Luck!

Re: HF 25% Off Coupon 9/2/19
Hi Tom!
Not necessarily so. We went through this the last time, same situation, same disclaimer, and on the day of sale I submitted the coupon code online and it worked. There's a post about it, complete with picture, over in the 7x12 group. Anyway, who really knows for certain?
If there is something you'd really like to have, put in in your cart and apply the coupon code, even if specifically excluded. It might work, and it might not...give it a shot. I'm going to try it on a mill and a lathe on 9/2 just for my own information.

Re: HF 25% Off Coupon 9/2/19
Sadly, the coupon *EXCLUDES* Central Machinery items, which includes the lathes and mills, horizontal hack saws and most large items these days. You usually get the lowest price these days for waiting for items to go on sale, since the coupons no longer apply to so many bigger ticket items.

OOPS! Note that the correct date is 9/2/2019, not 9/22/19.

Ok, thanks!
Beautiful work, beautifully photographed as always, John!

On my lathe I have a section keyed to the spindle with holes to take a
pin on a lever. This manually engages to lock the spindle to allow the
chuck to be unscrewed. If I wanted a Spindle clamp I would remove the
lever and replace with a simple OD clamp like a big end on a conrod. I
am not too bothered with X and Z as I would be using one or both in a
process in conjunction with the indexing capability.

perimeter, then I made up a ring that
clamps between the chuck and the spindle flange. later i prefer, as?I
now run a 125 mm chuck
regularly and have not bored this chuck perimeter.
All holes are 15 degree apart. Good enough for nominal splines and
key-ways.
The ELS angle display is right on the money comparing my bored ring
and chuck holes, or is it the ELS is
correct to my bored holes.
Either way, the bored holes were put in using the Arduino step indexer.
The indexer pin is spring loaded and slides into a body that clamps to
the lathe bed.
Just unclamp when not required.

No. Any locks needed to combat rotation, movement or backlash are up to
the operator.

Is there any provision for locking the spindle (mechanically), cross

during indexing? Some machining operations (drilling, tapping, etc)
could cause the spindle to move out of position. Or is this a not

The ELS options are Feed Control, Taper cutting, Threading, and Indexing
The control panel for the system has 5 momentary buttons, four in a N E
S W layout (cross), and one the the left of this set. The four in the
cross can be thought of as up, down, left, right. The other button is
the selection button.
Presses of the selection key cycles you through the options discussed
and their sub options.
When you are in the Indexing option the screen will show
??? Req:? 0.00???? z:? 1
??? Act:? 0.00???? a:? 1
Act: shows the current position of the spindle in degrees
z: shows the required number of increments
a: shows the current number of increments
Req: shows the required angular position for the current increment number
Presses of the Up and Down button will increment or decrement the z value
Let us assume that we want 100 divisions on the OD of a dial which is in
the chuck. We have a Vee shaped tool which we can traverse across the
dial OD to leave a groove.
Press up to increment z: to 100
Traverse across the dial OD with the tool
Press the right button to increment a: to 2
Req: will now show 3.6. Manually rotate the spindle until Act matches
Req. If you overshoot you can reverse.
Traverse across the dial OD with the tool
Press the Right button to increment a: to 3
The display will now show
??? Req:? 7.20 ? ? z:100
??? Act:? 3.60 ??? a:? 3
Manually rotate the spindle etc etc
Some may find this option useful some not but it is there as the use of
the encoder for the primary ELS functions makes it available.
Any queries just yell.

scratch two lines 180 deg apart on the OD of a job for a further
operation. It could be used for engraving a dial.

Sorry for not posting regularly it?s been a bit manic here, I repair musical instruments and it?s been Fiesta time with many
bands needing repairs and adjustments and they all want them at same time.
I would like to start a set of new topics including the ELS and a new one for Charlie to #ESI ?( Electronic Step Indexer).
The posts will include but not limited to the manufacture of the late John Stevenson 4 and 6 sided blocks.
As we go along through the weeks of posts, even these blocks go through a radical change.
Necessity the mother on invention syndrome. But leave this till later.
So firstly a group of photos showing the turning of the blocks made from aluminium.
For my needs this material is OK, if you want to follow with manufacture in steel that?s OK too.
With the ELS, the external 40 MM x 1.5 mm threads were cut, the internal 8 deg taper also cut. No compound slide needed.
ELS will do it all for you.
So pictures worth a thousand words, note.perfect taper finishes using the stepper motors, not manual.
ER 32 nuts i bought.
Any questions at this early stage please ask.
Hope we all have a productive September, lots of chips or plastic being squirted.

good point, and the Arduino is at the core of many 3D printers.

Hi Ralph!
Apparently I am in the same boat, as #hashtags are new and somewhat foreign to me and not part of my generation. Hashtags are a means of sorting or filtering out what you want to read...if you love ELS but hate discussions of #3D printers, you can use the hashtag to keep your eyes from being offended by topics that may not pertain solely to ELS. Or at least that's my understanding.
#Hashtags remind me of pointers in C in that they point to the various topics.
As for suggestions of another #hashtag, even though we are not there yet, I think #ARDuino might be a good one. It appears that an Arduino is at the core of the ELS, and if so, you will likely have to know how to compile the code without errors and upload it to the Arduino.

Thanks, Eddie,
I'd tried to sign up for a course on Solidworks 2018, but couldn't do it on my phone, and your email reminded be before I missed the chance.
