Use of circular tables.
Most dividing plates will fit on a circular table. reasonably priced from Arc Euro Trade UK.
4" tilting head to 90 degree table also Arc Euro. Photo 1 shows a typical dividing/indexing plate installation.
I needed to do some modifications to fit the plates onto the 4" circ table handwheel arrangement, but
maybe the newer model tables have bolt staright on arrangements. certainly my 6" circ table was plug and play.
The 4" table Charlie shown in his excellent photos is the standard degree hand wheel and agree what he was machining did not need?
dividing or indexing.
Dividing or Indexing head no fraction spacings should not be confused with angular dispalcement. Degrees min secs.
Circular tables are normally 40:1 72:1 or 90:1 ratio. for a complete 360 degree movement. IE 72:1 ration, means 36 full turns will move the table 180 degrees.
Commercial bought indexing plates normally are 4 in a set with holes ranging from 15 thru 65.
I have attached a spreadsheet for 72:1 ratio plate and part turn selections.
For 40:1 , 90:1 ratio circular tables just read the SS instructions on the RH side and alter, then save under a new file name.
File cells should not be locked .
Hope this helps
