Shaft log to hull clearence,

[Peters Wet]

Hey all I'm in the process of repel wing the soft log hose on my Mark 1 Catalina 30 and am encountering a problem with the fit. The log has an o.d. Of 1 1/2 inches and to install the proper 5 ply hose there isn't sufficient room. If I can fabricate a tool that will grind out the cavity I can make it fit but wonder if that's advisable . Is it just poor design that left the clearance so limited or would there be an issue with grinding out a further 1/4 inch of glass?
Tunas in advance for your input 😀
