Slimline Rotary Table 150mm/6 inch

[raynerd]

I have a 4" Vertex sat infront of me now!   

Just need to figure out how I`m going to mount my boxford 4" pratt 3 jaw to it 

[John Stevenson]

Weld it on ?

.

[Jasonb]

Chronos do an MT2 adaptor with a Boxford thread to fit the Vertex

Don't be lazy, make one ...... be good practice

Weld it on ?

.

Is that a serious suggestion? I can imagine making the jaw a perminant fixture would impede some alternative uses of the RT???

Jason, thanks for the suggestion, I had seen these but with the myford at £12 and the boxford at £35, I wasn`t willing to pay that. Thanks for the link Darren. It could very well be my next project.

lol - it isn`t even setup on my mill yet. It is currently on the kitchen work surface so Mrs Craynerd is   to shift it. I`m just trying to get my head around it ... 360 deg, 60 mins, 60 seconds. ....  90:1 ratio so 1 rotation of handle is 4 deg ... yes yes..

So say I want to cut 14 holes around a diameter, 360/14 = 25.71428...

I`ve been trying to figure this out all day, but since the RT is not split in decimals but deg, mins, secs .... how can you convert it? I`ve found a little calculator online that will do it, but I`m struggling getting my head around the maths!

EDIT:

Just found this:
Here's How:
The whole units of degrees will remain the same (i.e. in 121.135° longitude, start with 121°).
Multiply the decimal by 60 (i.e. .135 * 60 = 8.1).
The whole number becomes the minutes (8').
Take the remaining decimal and multiply by 60. (i.e. .1 * 60 = 6).
The resulting number becomes the seconds (6"). Seconds can remain as a decimal.
Take your three sets of numbers and put them together, using the symbols for degrees (°), minutes (‘), and seconds (") (i.e. 121°8'6" longitude)

Chris,

Download the ROTARY program from my page and it will do all the dirty work for you.  As an example, here's the program output for your example of 14 divisions.

Code: [Select]

Number of divisions = 14

DIVISION      degdec     deg     min     sec
       0      0.0000       0       0       0

       2     51.4286      51      25      43
       3     77.1429      77       8      34
       4    102.8571     102      51      26

Thanks Chris for the explanation, that really clears it up for me as I had no idea 

And Marv, I'm off to collect your program 

[raynerd]

Thank you for the software Mklotz -certainly makes things easier!   

lol, I`ve just spent ages opening up the program, putting in the number of divisions and hitting return and the program vanaishing! What it is not working   only to find the rotary.out document waiting for me with the "answers".

Still don`t get the maths in the conversion but right now got a headache so will have to wait for another time!

Darren, finally something I said of use lol

[John Stevenson]

From Marv's main page................

***********************
 If you're too lazy to read this introduction, at least read the last four paragraphs so I don't have to waste my time answering questions already answered here.


A number of DOS-challenged users of my programs have written to complain that when the program terminates, Windoze, in another one of its mis-guided attempts to think for the user, closes the window before they can inspect the answers generated by the program. Dave Wood has spent some time working out how to keep Micro$oft's abortion from trying to outthink the user. He writes:

In Explorer, right-click on the .exe program name. Select "Properties". Select the "Program" tab. At the bottom of this dialog is a single check-box "Close on exit". Un-check this box. At the bottom of the dialog click on "Apply," then "OK".

Gee, when the program runs it prints out the following advisory:

Your data is on: ROTARY.OUT

Is there some way I could make it more obvious?


I see that John has already advised you, should you use other of the programs, to read the Introduction on the page, lest I reach through the tangle of internet cabling, out your monitor, grab you by the neck and thoroughly throttle you.

Just kidding.  Like Sir John, I'm a real pussy cat.  Nevertheless, program users are well advised to read the Introduction.

[raynerd]

lol  mklotz - I did find it in the end by reading your home page, all be it after I had made a few attempts!

No there is no way of making it clearer - it just takes an eager fool a little time to realise! I have just checked it again mklotz, and I do not get any message like you said. There is something that looks to flash up but vanished within an instant. Anyway, I did get it in the end!

[mklotz]

The reason you're not seeing the message is discussed in

wait for it

THE INTRODUCTION

You need to do what's advised there.

Now, lean forward closely toward the monitor so I won't have to reach so far. :-)

I just went through all that to see : Your data is on Rotary.out  ???

I`m sorry Marv, Ì`d taken the context of your introduction wrong - I`d taken it to mean that you don`t need to do that. As though someone had thought the program was closing without giving the output and so you had to do that to stop it closing....

Anyway, this is all irrelvent, I was sucessfully using the programme after 5 minutes of downloading it ..... many thanks  

[mklotz]

In the case of this program, yes.  However, understand that a number of the other programs write their output directly to the screen (as opposed to a file) and you would never see such output if you didn't disable the close-on-exit "feature".

In general, if the program generates only a single number or two, it writes that information to the screen.  If it produces complex output or tables (as is the case with ROTARY) that need to be printed and carried to the shop, the output is written to an ASCII file.  Since these files are ASCII, you can load them into any editor and annotate them with your own commentary before printing them for the shop.

[raynerd]

Thanks - excellent programme!

[raynerd]

I`m looking for the Dividing Set Plate for the 4" Vertex but unfortunately all the usual suspects RDG, Arc Euro and Chronos are out of stock. Does anyone know anywhere else I could try or any other sets that would fit the vertex, for example Chester sell a set for their RT and it is more expensive but don`t know if it will fit the vertex.

I`m really hoping to get a set within the next few weeks so any suggestions to alternative suppliers greatly appreciated.

Chris

[Jasonb]

Engineers Toolroom have them listed

http://www.engineerstoolroom.co.uk/milling_accessories.htm

Jason

[raynerd]

Jason, thanks for the sugestion, I`ve never used them but they are listed for the 6" hv6 and not the hv4 - it could be the same. I`ll ring and ask later.
Cheers
Chris

[raynerd]

I couldn`t get through today and want to order this asap. Does anyone else know if the 6" dividing set is the same one as the 4" only looking at RDG website and although it is out of stock it does say: VERTEX DIVIDING FOR 4" & 6" VERTEX ROTARY TABLES -  THIS DIVIDING SET FITS, HV4, HV6, VU100, VU150

I`m taking it that it will only I have also found Warco selling them for £35

http://www.warco.co.uk/Dividing-Plate-Set-for--HV6-49C5EE5C31.aspx

Anyone ordered from Warco before, are they OK in terms of delivery times?

Chris

[colin563]

i know the dividing plates come with the hv4 & hv6 from warco

i got the hv4 from warco also the tail stock at the midlands show

 not sure how it all works yet ?

i will get round to that when i need it

colin

[bogstandard]

Just go ahead and buy it from Warco.

It should fit perfectly, but even if it doesn't, a little bit of tweaking with an axe and angle grinder will soon have it doing the job it is intended for.

But prepare yourself for the mental onslaught when you come to use it. It is a read, understand, and inwardly digest exercise, that only yourself can carry out. It is easy once you can get the rhyme and reason sorted out.

Also when using a dividing head, it is purely a no disturbance exercise. Just one little hiccup or lack of concentration can ruin hours of very accurate work.

You will also realise that with a basic dividing head, such as this is, NOT EVERY NUMBER IS CATERED FOR. There will be a few obscure ones, that if you do desperately need, you will have to make up your own dividing plate (or get someone to make up for you).
John Stevenson might be the one to approach in that situation, I know he does ones for Myford heads.
