Mr Peacock's Indexing Attachment
Hi All,
After a bit of interest about my indexing attachment I've measured it all up to share.
Just a bit of info first. My Dad, Ian Peacock, was a great man. Sadly he passed away last year. Anybody that came across him at any time during his 40 years of teaching will tell you what a good bloke he was. I'm proud to say that I've inherited my Dad's ability in the shed and it's translated into my 15 years so far in heavy industry as a fitter.
I grew up using the Hercus that now sits proudly in my shed. Have been schooled on it for years, so it's more like an old friend, than a machine.
So this write up is a bit of a tribute to my Dad.
He made this attachment. I'm not sure if he gets all the credit for it's design, or if he got it from somewhere else, but like everything he did, it's a masterpiece.
You'll notice I started to draw everything in imperial, because I thought that's how it'd been made, turns out it's a bit of everything. I'm sure Dad just used whatever sizing was needed and whatever he could get his hands on.
The only part I'm unsure of is the spring loaded catch. As it's peined together, I can't tell whats inside. So I've drawn up what I think is in there.
If anybody would like larger images of the drawings, I'm happy to email them around.
Enjoy.

Hi BEE55T
Thank you so much,on a couple of levels.
First up, thank you for telling us about your dad.Being a teacher myself, I think its great that he has passed so much in terms of knowledge and skills and the effect this has on our society.
In 40 years of his teaching,just think of the number of students who have been enriched by the skills and knowledge your dad would have passed to them.Those students ,in turn have gone and in the course their lives have produced for the benefit of our country.
Secondly thanks for posting pics and drawings ,it will help me improve my meagre machinist skills. Be assured the info has been filed in my" List of things to make" File .
If I live another 20 years or so , I may get to make a tiny fraction of what I have filed away.This one will be the second, the first one being almost finished -the adjustable segmented folder that is posted in our forum.
While my lathe is not a Hercus, the gear train arrangement is close enough for me to copycat your pattern.The beauty of it is that it is a relatively simple project.
Thanks very much for taking the time and effort to do this.

Thanks very much Dave.

No worries guys,
I suppose I'm a bit like my dad too, I like to share my knowledge. Either that or I just like to carry on.
My dad touched everybody he taught. He was just one of those teachers that got called Sir. He was offering my brother's mates one of his beers one night, and they were still calling him Sir.
Grahame, you sound like a teacher.... things in files. We went through my dad's stuff, he had a file labelled "useless information". And another marked "even more useless information"
Sorry the drawings weren't exactly to standards, but it would have taken me ages.

Thanks Dave. I've started making mine. I got the bulk of the main frame completed today. Just have to clean it a bit more.

I'm going to build one too in the next few weeks as I need to cut a 32T gear. I'll try to find another way to lock the gear as I feel the locking assembly is way above my current level of skill.
The sketches and photos sure been a great help to a newbie like me.
Appreciate and thanks for the effort made.
