Filter Slide Question(s)

I enjoy making my own astro equipment when feasible. I use an Orion 10" dob (f/4.7 with 2" focuser) and currently have two 1.25" filters. I'm tired of the thread-on, thread-off routine and would like to make my own filter slide using my 1.25" filters. Is it possible to use these filters without cutting off the outside of the light cone?

I have nothing against buying the Astrocrumb slide other than the apparent need to (gulp!) buy 2" filters...
