10EE 4 Station Micro Carriage Stop

In an earlier thread I detailed a recent move picking up a 10EE. One of the attachments it has is a 4 Station Micro Carriage Stop. After looking through earlier threads here it looks like it probably isn't one of the more common attachments although I did find pictures of a few in much better condition than mine. Another member here offered to purchase mine and although I haven't decided to sell yet I wanted to at least clean it up to see what I have. This first photo is a close up of what it looked like on the machine. As you can see, this lathe has been neglected for many years but it's been inside and covered with a greasy muck which protected it pretty well.



In order to get it clean I decided to disassemble it completely. It's pretty amazing how many parts it took Monarch to do a proper job on their stop. They certainly didn't cut many corners back in the day.



It does look much better after getting rid of years of crud but it looks like it was probably never removed after delivery. It's taken some abuse over the years with some dings here and there.




One of the things I wanted to do if I decide to take him up on his offer is make up some drawings in case I ever decide I need one of these some time in the future. There is nothing real complicated about any of the parts other than the base casting depending on how you're equipped. It could make a fun winter project. I started a model this weekend and I can make up drawings when I'm finished with it if anyone's interested. Let me know.

I would be interested in drawings. There are multiple threads on what castings people would want, but I don't think anyone has perused getting castings made. I know there are some local aluminum foundries but I don't know of any doing iron - I'll make a couple calls to see if I can find a local one.

I wasn't really thinking of getting castings made. I would think the expense would be prohibitive for the small numbers that people would be interested in if done commercially. I was thinking of machining the base casting from solid cast iron. It may not be an authentic reproduction but I was thinking more of the practical use of it.

I can say first hand that these are very handy, I have a set of extensions dedicated to the fixture. Mine came with two inch and two metric heads, Starrett and Lufkin rods and heads both fit the sleeves in the fixture.

The overall size is small enough that a solid block is a practical way to recreate these in small numbers.

yes - my solution has been to make parts starting with dura bar (made dial indicator holder and have the material for the taper clamp). I was not looking for you to check into castings, I was thinking of doing that myself. I know there are local aluminum foundries but I don't know about other materials, I was going to see what I can find.

The 4 position carriage stop is not difficult to make from a weldment. The one shown in the 6th and 7 th picture may be a little crude, but it has been quite effective.

I've had the pleasure of re-learning aspects of my CAD system I don't use very often if at all. As a disclaimer, I am not an engineer or draftsman so cut me some slack on my drawings. I have some other projects coming up that will require the same skills, so this has been a worthwhile project.

The dimensions on the drawings are generalized somewhat to try and capture the intent of the original engineer rather than being a strict representation of my parts on hand. Most measured dimensions were fairly obviously intended to be standard fractions.

The manual only has part numbers with no descriptions so I'm making up the descriptions as I go along. If anyone knows the proper names, let me know and I'll fix the drawings. Below is a copy of the parts list from the manual for reference.



I currently have a complete model and 4 drawings finished. I replaced the picture of the model in my first post with the completed picture since it wasn't finished when I captured the screen. There is some hardware that will need to be purchased listed below. Look the set screws up in Machinery's Handbook.

103-4 5/16-18 x 3/4 Socket Head Cap Screw, 2 ea required
511-3 3/16 x 7/8 Dowel Pin, 2 ea required
297-3 8-32 x 1/8 Socket Set Screw, 4 ea required
264-1 1/4-20 x 1/4 Half Dog Point Socket Set Screw
183-7 10-24 x 1/2 Half Dog Point Socket Set Screw
EE 1766 - 1/4 dia Steel Ball, 1 ea required

I wasn't able to get a very clear JPEG output of the drawings in a size appropriate for this site so I'll output PDF's you can download instead. The first 4 links are below. I'll try to finish up the rest this week.

EE 2530 Spindle
EE 2638 Turret
EE 2639 Stop Screw
EE 2640 Micrometer Head Mount

Nice job, I look forward to the rest.

Another project added to the list
Paul

Below are links to the last two drawings. There are some additional parts needed I will describe instead of drawing. Each 297-3 set screw has a brass plug under it to keep from damaging the EE 2640 Micrometer Head Mount. 183-7 Set Screw also has a brass plug to protect the threads on EE 2530 Spindle. Monarch forgot that on on their parts list so we'll call it 1000-3.

1000-2 PLUG, .125 dia x .125 Brass
1000-3 PLUG, .145 dia x .125 Brass
AA 2298 SPRING, .187 OD x .56 Free Length x .030 Wire Dia x 8 Coils

The dowel holes in the base on my stop aren't straight and the measured dimensions are somewhat odd compared to the rest of the part. If you already have mounting holes in your carriage they probably won't match my drawing and you'll need to fit it to your carriage on assembly.

Hi, Paul,

There have been a few 'threads' on the 'OWWM' (Oldwoodworkingmachines) internet site about having iron castings run by "Cattail Foundry', a small specialist foundry, which, according to some stories there, will do one-off or short runs of small and medium-size parts, when supplied with a pattern.

Allegedly, they do good sound castings, and their prices are quite reasonable for one-off work. Try an internet search on "OWWM', and a site search for 'Cattail Foundry'.

I have no personal experience with the firm, and know nothing about them, other than reading some comments on the OWWM board.

cheers

Carla

The indicator holder castings I was selling I had made at Cattail Foundry. They're nice folks, easy to work with and - most importantly - they work with loose patterns. The contact info is:

167 W. Cattail Road
Gordonville, PA 17529

I've worked with Emanuel King whose name is on the header of the invoice. I usually mail the patterns to them with a note telling them how many of each. The first time I included a check and got back castings, patterns and change. Anymore I send the patterns and he returns everything with an invoice.

Great work!
the dowel holes are drilled on the beast, hence the odd locations.
I have two of those and they don't line up at all, nor do they line up with the holes in my apron.
Best regards,
WC-

Yea - I figured whenever I get around to making one I'll proceed on one of two main options.

Use the 2 big SHCS on the left end (ones that hold the carriage to apron) - not wild about this option as this would make the base way oversized and I don't like the idea of using those bolts (would need longer ones).

I figure the better option is the end of the carriage. On my late square dial its threaded for the dial indicator adapter. I'll bolt up there, the other option would be to fit a dovetail like on earlier models and again fit it the same as an early dial indicator.
