Making accesories for my Clausing 6903 Lathe.

Post by Lu47Dan » Fri Mar 30, 2012 8:10 pm

I started making a fixture for mounting a dial indicator to the trapezoidal my lathe.

Cutting the stock for the clamp

Stock squared up, ground and slot laid out.

Relief slot milled into the clamp, the relief slot is to allow for clearance on the top of the way.

The next step was to cut the angles to match the way. This involved setting the block up in the mill at 35°, and then taking cuts off one of the corners. Since the two angles add up to 70°, you also have to trim the opposite corner of the groove to provide clearance to cut the groove to the proper depth. Once I had both angles cut I test fit it to the v-way.

Fits pretty good.

Close up pictures of the groove.

I will have to grind the faces of the angles to remove the tool marks on them.

I did finish up this project last week, and had to jump to another project
So here are the photos of the rest of this one.
Image
Clamp finished.
Image
Ready to locate and drill a 25/64" hole to tap at 7/16" - 20
Image
The clamp and base assembled.
Image
Ready to cut off the excess steel.
I used the drop piece to make the block that the Indicator mounts to.

I had to mill the block down to 3/4" X 3/4", I then drilled two holes to bolt it to the base.
Image
Test fitting the block.
Image
Block bolted down, indicator mounted and ready to be assembled.
Image
I milled a step into the end of the mount to help with alignment.
Image
Finished mount.
Image
Another view.
I have to drill and tap for a stop bolt before I paint the assembly.

The next accessory is a ......

Post by Lu47Dan » Mon May 07, 2012 6:09 am

Steady Rest
Image
The start of the steady rest, this flange is a 6" 150# RF Slip-on flange, it was just tacked to the pipe.
Image
The backside of the flange.
Image
The shoulder removed and the flange cleaned up.
Image
Cleaning up the face, the RF above in the description of the flange stands for raised face. that means the sealing face is about 1/16" higher then the rest of the face.
Image
Now the flange is a ring, 7/8" thick. 11" in diameter with an ID of 6-3/4"

The base and clamp block.

Post by Lu47Dan » Mon May 07, 2012 6:15 am

Image
The base machined and test fit.
Image
The base aligned as it will be in the final product.
Image
The clamp block. I milled steps into the end of the clamping block to help align it to the bed ways.
Image
The base with the bolt slot milled into it.

Machining the stands.

Post by Lu47Dan » Mon May 07, 2012 6:25 am

Image
One of the two stands with the edges beveled.
Image
Ring with the position of the stands laid out.
Image
The stands ready to clamp to the ring and the base plate.
Image
Clamped up ready to weld.

Welded up.
I will be working on the arms or fingers today.
Once this is finished I will give it a good sandblasting to remove the the welding smoke stains and give it an even finish before I paint it.

Andre, thanks. I trained as a Tool & Die Maker but never pursued it as a career. I could not stand at a machine all day now for sure. I have to break up the machining jobs into sections, so I do not get too bored watching the lathe run. The mill and surface grinder are easier to spend time on as they require operator input to function correctly.

Here are pictures of today's progress.
Image
Tubes cut to 4-1/16" for test fitting of them to check clearances.
Image
The tubes clear the carriage my a large amount, so I can make my hand wheel in the 2" range.
Image
Set up to mill a 30° angle on the top of the stands.
Image
Milling in progress.

More photos.

Milling complete.

The set up.
Milling the angle on the two stands was done so I could get the steady rest as close to the chuck as safely possible.
Image
Ready to start machining the pieces for the telescopic arms.

Andre, making my own tools is a lot easier than it use to be! :lol:
The rain that had been holding up a couple of other projects, let up around noon today. So I finished cutting up an old truck that pieces of it will live on in another project of mine. I had the rest of that truck two old trailer and a front suspension from another truck to cut up and send to the scrapyard today.
I saved the pieces I needed and the rest of them will go to the scrapyard in the morning. I still have the front suspension from the first truck to cut up in the morning as I had to pull the engine out of it before I could cut it up. I just plumb ran out of light to cut by tonight.
I saved the rear axle out of the truck to get the spindles and axle tubes out of it for the project in this link.
http://www.shopfloortalk.com/forums/sho ... php?t=6677
I have been gathering parts and pieces and the machine tools to build it for about six years.
The steady rest will be an integral part of the machining of the axles for that project.

I got the final materials for this project today, a 3' piece of 3/8" threaded rod and a 4' piece of 1 X 1 tube to make the telescoping arms.
I might get a 7/16" - 14 tap and go bigger with the threaded rod, instead of the 3/8" rod.
