Some background info first. I have a project where I need to make new raised panel doors to match existing raised panel doors. The profile of the raised panel is such that I cannot find a router bit that matches it. Fortunately I was able to find the profile with Amana shaper cutter no 931. The thing is that I have zero experience using a shaper. Hence this call for help.

I found a place where I can rent time in a shop that is equipped with a shaper that has a 3/4” spindle. So I would like to use cutter 931 with a suitable ball bearing on a 3/4” shaft. How do I do that? What T-bushings or sleeve bushings do I need? What ball bearing can I use?

Here are specific issues I have in mind:

Bearing Selection:
Amana recommends the C-017 ball bearing for cutter no 931. Inside diameter 1 1/4”, outside diameter 2 1/2”. Should I use this bearing with a 3/4” to 1 1/4” bushing or should I use bearing C-016 which already has a 3/4” inside diameter and a 2 1/2” outside diameter? It seems that using C-016 would be simpler (no bushings needed) but is that OK?

Bushing Selection:
The web page for cutter 931 says that replacement T-bushings for that cutter are BU-720. However that bushing has a 1” inside diameter. I need 3/4”. Would there be anything wrong with using a 3/4” to 1 1/4” bushing like BU-600? Is there a safety issue here with such a large cutter?

Stacking the Components
I am unsure how to stack the various components on the shaft: T-bushings, sleeve bushings, cutter, ball bearing. What would be the exact sequence assuming the shaper’s rotation direction is the same as a router table?

I contacted Amana about this. The guy understood my questions and made suggestions but I could feel he was not 100% sure about this.

Thanks for your help

I have a raised panel door company, so maybe I can help some.

Bearings and T-bushings—You can actually go either way. I couldn’t find Amana’s T-bushings and bearings so I can’t give you their numbers. Some manufacturers offer long and short T-bushings. The long ones would go throught the panel cutter and into the bearing. Use one short and one long. I do this all the time. Then you can stack the bearing either on top of or below the cutter, depending on the rotation of cutter and shaper—and whether you are cutting face up or face down. Also a factor is going to be whether you are using a template for the bearing to ride against or running the bearing directly against the workpiece. You could also need a spacer.

Stacking components—This will depend on all the variables mentioned above.

I will also Pm my phone # if you need more info
