Rotary Table turns counter
« on: April 08, 2009, 07:36:11 PM »
Hi All,
Last week I officially joined the Senior Citizens Club.So this would explain the difficulty I now seem to have remembering how many turns I have made whilst using my rotary table dividing plate.I wondered how I could mechanically count these. I remembered years ago the little counter thingey on the bicycle front wheel (think it told you the distance covered) So with that in mind I had a look on Ebay and hey presto I found one for £3. I made a small aluminium plate that slides in the milling table t/slot.I pop riveted the small counter to this  and put a small pin to strike the counter on the end of the indexer plate.Simple but effective and helps a poor old devil like myself who is gradually loosing his marbles!

Very nicely shown Mick, ingenious little device you have working there.... :thumbup:

Nice one Mick, anything that helps us old foggies out has to be good.

It would save me having to take my shoes and socks off to count above ten.

Without the humour though, it is so easy to forget the count, I do it a lot when dividing, and have to wind back from whence I came, to get to start all over again, and your solution has got it covered.

You could always keep a pair of old gloves handy for the big numbers. :med:

Sorry I cant view the video (broadbrand is rather narrow here!) but it sounds like a great idea Mick. :thumbup:

You can buy lots of types of turns counters that are intended for electronic equipment, there is one on this page but you need to scroll down a little to see it.

A few of them are relaxing in one of my bits drawers.

Tried the fingers and toes trick but still lost my count. I thought there was possible an electrical solution but being more mechanically biased chose this path. Hi Stew yes! got windscreen wiper motor drives on vertical and horizontal drives and they are still going great guns.

Hi Darren,
              The milling machine is a Chester 20 v and  I have already posted the YouTube vid showing the windscreen wiper motor drives on the horizontal and vertical planes.They are powered by one old PSU out of my computer. Its on the home base --introductions--page 2-- New Boy On The Block. It was posted in January. The vertical slide is especially helpful as its a right old pain winding by hand.Word of warning though! make sure the slide clamps are off I have also incorporated a small brass shear pin in the coupling which will  hopefully do its job if called upon.

cheers Mick

Thanks Mick,

I thought I'd read every post on this board but I hadn't seen that one before  :scratch:

In case anyone else missed it you can find it here http://madmodder.net/index.php?topic=640.15

I'm going back for another look  :thumbup:

This is going to become a growing problem from now on Darren.

The site is now getting rather large, and with it all the topics and postings, it can become a nightmare finding the posting you want to read.

It is for that reason, the topics must be worded correctly and put under the correct headings.

The search engine, once the site gets very large, becomes even more important in finding things you are interested in, but also to do a search before asking questions, as it just might have been covered before, and it saves the members a lot of searching themselves to get the question pointing to the previous answers.

That is the burden of success.
