I wanted to thank everyone who responded to many of my dumb questions regarding my shaper. It is up and running. These things are a lot of fun!!!

Here is a test of a cutter for a job that I need to do. The test is in aluminum, the actual job will be in DOM tubing. Couldn't do it on the mill, at least not with the tooling on-hand, the grove follows the circumference of the OD of the material.

:encourage: Awesome, congratulations! I love running mine.

That's a very cool groove, following the perimeter like that. Must file that away for future reference....

Great to hear your machine is alive and performing. Post photos of your machine now and any set ups. Yes, they are fun to run.

Will do when I have a setup and am ready to run. Right now I need to make a boring bar setup for the shaper. I saw a Turn Wright Machine Works/Keith Fenner video where he made a bar to go directly into the clapper box. That looks like a very rigid setup, anyone have any pros/cons to using a tool holder to mount a boring bar vs. the direct mount?

I've had both. Currently have a holder mounted one, I needed the reach to get closer to the table. Being lower also helps stop the tool from rising in the cut. Straight out in front the tool wants to rise out of the cut making it necessary to lock the clapper.
Nice work on the keyway.

You can make a boring bar holder for your shaper using a split or two piece rigid shaft coupling welded to a piece of flat bar.

Here is a similar bar holder.

Thanks for the photo, I will file it for future reference. I'll go this route when I need a larger diameter bar to resist flexing.
That looks like a nice shaper you have; what are the details?

Reeltor,
I found the photo on the PM site. My Shaper is a 1956 24 in. G&E universal similar to yours, just a little bit later model. I am always interested in how Shaper owners approach their work and the set ups used. Keep it working and send more photos. Have fun and be safe.

I need to make an auxiliary table so that I can mount some work in a dividing head. I'll post some photos when the setup is complete.

So, maybe an obvious question, but can you slot the inside Diameter of work with a shaper? If so, are there any restrictions on how deep into the bore one can go? The specific instance I am thinking of is making a set of 1" ID spacers that slip over an arbor for a horizontal mill. The spacers typically have a key way cut into the ID. At present I don't have a broach set and just missed buying a slotting head for my VN 12. So have no good way to cut inside diameter slots.

Maybe I need a broaching tool.....

Glenn,

The short answer is yes.
now, I am not the shaper guy to ask... I think I may have used a shaper once back in college and maybe back in the 8th grade.
After watching Keith Fenner's video that I posted above, the issue with cutting a key with a small diameter boring bar is bar flex. But since you are wanting to cut a keyway in short length arbor spacers for your mill I don't see a real problem.
For this application, I would just buy new arbor spacers, since I don't own a surface grinder to get the ends parallel. Enco used to sell these, I bet MSC still has them, the problem is finding them on-line IIRC they named them something that didn't occur to me.

good luck

Mike

As Mike said yes. Guess you could cut as deep as the stroke of the shaper, but the flex in your bar might be the limiting factor.

Reeltor,
Auxiliary table.
You are located in a large metro area, so opportunities may be around you. Check with the local machinery dealers or scrap yards for fixture plates or machine tables. An old milling table could be cut down to fit. I am going to make one for my Shaper from a cast iron fixture plate on hand and tap the top 1/2-unc for clamping tooling. I will drill through and counter bore to mount to the Shaper table. You can also make a sub-base to extend the table reach. Look forward to seeing your table at work.

The nice lady from the post office delivered a Boring Bar Holder today. I got it from Uglydog; he has a very limited number of holders, if anyone is interested please contact Daryl directly for availability and pricing.

Mods, if this violates any rules please delete it.
