Vertex BS0 dividing head

[BoldminerParticipant @boldminer]

Can any-one out there explain the meanings of the ‘A,B,C,D,E and F’ rows in the divding tables at the back of operating instructions manual for the Vertex BS0 model dividing head. Also what do the numbers in these rows refer to?

[JasonBModerator @jasonb]

Probably the letter is to identyfy which plate and the number is what ring/number of holes.

Speaking of indexing, I would like to get a comprehensive set of photos of Ivan Law’s home built Universal Spiralling and
Differential
Indexing Dividing Head which was featured in MEW a couple of times and
probably in ME as well. Large format would be ideal, no file is too
large!

 

This was made between 10 and 15 years ago. It’s a
semi-replica of a Brown & Sharpe original but scaled down to 50% or
lese of the original size. I have some info on the original B&S
heads and a small amount of info on Mr. Law’s but photos from various
angles would be extremely helpful. (If anybody happens to also have
size info, that would be extremely helpful, things such as center
height, DP of gears, spindle taper, etc.)

 

Please, if you have something useful send it, don’t presume somebody else will take care of it.

 

Thanks.

P.S. I was going to insert a photo of a B&S version but I can;t figure out how.

Hi Anthony,

 

To put a photo up it must be stored somewhere like Flickr or PhotoBox or even in an album on this site.  You then copy the location of the picture (right click on picture and copy location) and paste it on the pop up box which comes up when you click on the picture icon above the message creation box.

 

It would be great if there was a ‘help’ facility to show people how these things work.  We’ve asked but there has been no progress – hint hint Kelvin.

 

Hope this helps

These letters and numbers refer to the position and gear size to use for differential indexing with the BS2 Dividing head. Used to get divisions unobtainable with the use of a single indexing plate as on the BS0.

[JasonBModerator @jasonb]

Thanks for that Saxalby, I had suggested this may be the answer via PM, looks like the instructions cover all the Vertex dividing heads as I found some instructions on-line for a similar head to teh BS0 and that said the 96 divs that Boldminer wanted were not obtainable with the BS0.

 

The other letters in the table have the numbers 64 & 40 which I assumed were the gear teeth required on teh BS2 head

A way to get the 96 divisions is to make up a small index plate with 12 holes.  Then you index 5 holes per toothy.

I was re-reading an article by Bryan perkins last night, from 2001. He claimed the usual sets of dividing plates supplied with the common 60-tooth gear heads really suited the 40-tooth gear heads. I don’t know if this is still the case…

Thanks to every-one that took the trouble to reply to my query. In the end I realised that 96 divisions where not possible using the  BS0 and the plates supplied. A trip to a local engineering who gave  me a 6 x 100mm. dia blank. This enabled me to make a new 24 hole wheel. I know a 12 would do the job as well but whilst I was drilling for 12  I might as well drill for 24 ( looks a bit better I think ). Anyhow problems solved and the jobs done, thanks again folks.

Hi there

 

I have a BS0 deviding head and I was confused by the manual as well. I found that I could not get the divisions that I wanted so I purchased a “Division Master” and stepper motor from the Model Engineers Digital Workshop and now I can get any division I want and I don’t have to worry about turns and holes. One of the best things I have ever got. Just a very satisfied customer.

You only need to store the photographs on your own computer, you then identify the location, C:/….when you enter the information onto the upload section of this site when you access the My Photos etc.

Quoting myself above, here are photos of the type of B&S dividing head of which I was speaking:

I'd really like to get a design for this type of dividing head with a center height of 2.0" or less.

Me too … 'though I would use it with a stepper

Anthony,

There are some references to the Philip Duclos articles, here.

… and a useful photo, here.

Michael,

I appreciate the suggestion but taint the same thing. I'm interested in inclusion of the differential gearing for divisions not available with the standard division plates and the ability to gear the dividing head to the feed screw on a mill in order to do spiraling work.

Fair comment, Anthony

I only referenced the Philip Duclos design because it's the first really small Dividing Head that I've seen with the [approximately B&S style] tilt facility … which is the feature of particular interest to me.

Obviously, if you need the Differential Gearing, it would need some development.

Anthony,

If you haven't seen it already, this is a good place to start.
