35 wheel repair

[Jakno]

Preparing to make repairs to my 35 steering wheel. Using PC-7 for the fill material. Purchase the Jack Turpin steering wheel restoration handbook to help in the process. The book has a lot of good information but I do have one question for the readers. The book mentions beveling the existing cracks in the wheel but does not give a lot of detail in how much to open up the cracks (1/16,1/8, 1/4") or how deep to go. The pictures show some of the typical cracks in my wheel which overall is in decent condition.
I want to do the wheel myself and hoping for good results. If you can share your experience I would be grateful. Thanks and Happy New Year from Dover Foxcroft, ME.

I opened up mine in an inverted "V" manner. The part closest to the wire core is larger than the the part closet to the surface. I also drilled some holes in the side of the opening to give the epoxy a better grip. I filled the gap in stages, allowing a stage to cure before adding more epoxy. I also sanded between stages to give some "tooth" for the new layer to adhere to.

The large cracks should be opened up to the core, and it is advisable to do the same for the smaller cracks.
