I have this 125mm x 50mm Amana steel rabbeting block with shear cutting carbide insert knives and knickers - https://www.toolstoday.com/v-7718-61482.html
I have a some work coming up that would really benefit from having a pattern cutting setup in place and am wondering if I can use this rabbeting block with a rub collar type bearing as a lower budget pattern cutting setup compared to buying a separate spiral insert head?
If so, is this what I’m looking for?

I want totally flush cutting with the template so I’m assuming a 125mm OD on the bearing is what I after. I’m confused because the photo of a red aluminum solid disk with a bore in it does not look like a rub collar but maybe the photo is wrong.
I realize that this setup is limited by the height of the cutterhead (50mm) and is a relatively large radius cutting circle (125mm) and will limit how tight of a radius I can cut. I think for the upcoming project, neither one of those constraints will matter. I’m sure I will end up with a nice separate insert pattern head at some point in the future, but wondering if a $30-40 bearing collar will accomplish what I’m after in the short term compared to a $200-800 insert head.
Any thoughts? Thanks!
