Once upon a time there was a lot of fuss about the non-availability of indexing attachements
for the 7 inch shapers that Atlas and South Bend had manufactured.
So I designed one, published the plans on the net, and built one to prove
to myself that the design was viable. Here are the pictures with minimal
descriptions. This was a really fun project in every way. It is for sale. |
The painted indexing attachment ready for the user. This has been listed on
E-Bay without the gear with a reserve price of $750.00 plus the shipping.
What you see in the painted indexer is what you get. I have one more set of flamed plates if any one is interested in them. They are all ground on both sides. Price $100.00 per set plus shipping payable through PayPal. They are heavy so shipping will be about $40.00 or more if you are far away. (in USA) . Well worth the price if you would like to make and own an indexer. These indexers are very rare and they go for about $1400.00 when and if ever available on the internet. My drawings are posted at http://finance.groups.yahoo.com/group/Metal_Shapers_Pix/files/ if you would like to look at them, they are under "S7 Indexer Attachment" as Autocad 14 files and you can download them at no charge. They are not 100% true to the indexer I built above. As always I welcome your comments. Enjoy. |
The three flamed plates and a mock up layout of what the indexer would look
like when done. |
Either a gear or a plate may be used for indexing. Pin mechanism close to completion. Note the three mounting holes Finished divinding plate ready for drilling the holes through and clean up. |
Two views of progress on the head of the indexer. |
Headstock pictures. Misc. |
Headstock spindle fit up and tailstock across from headstock. Headstock detail |
Early headstock machining picture. The counter weights are 14 Ga plates so
I can use as many as I need. I needed two stacks here! Dividing plate mounted on face plate and ready for holes to be drilled in it. |
Holes being drilled in the indexing plate. 60 Holes are the most useful and can be used for 2 3, 4, 5, 6, 10, 12, 15, 20, and
30 divisions. |
Finished talistock, ready for cleanup. |
Head and tail stocks read to have the bases machined |
Machining the spindle between the chuck and a ball bearing center. |
Clamp was made new and was the first thing I made one evening as I was getting antsy
to get on with the project. Head casting and spindle. The back of the spindle has not been machined at this point. |
Checking the set up for machining the holes in the headstock and in the tailstock
on the same set up so that they will have identical center heights. |
All done with the machining. Ready for the paint brush! |
The finsihed indexing attachment ready for paint. This is a very heavy duty
unit and should allow one to make whatever one has in mind without worrying about
the indexer flexing. This one has the threads for a Myford chuck (1.25
x 12 tpi). Another spindle is easy to make. The capacity of
this indexer is 5.5 inch round by 8 inches between centers (max). |
This is what you will get |
Views of the machined headstock with the dividing plate attached. Machining
is complete at this time. |
Note that the entire indexing mechanism has to be attached to the head, not the base. |
