Doug,

I've attached the spinner cut-out pattern I send along with the spinners I make. The pattern was taken off the installation in the photo (360 with 68" Hartzell). The cut-out provides for a 1/4" clearance around the blade and provides clearance behind the blade for full coarse pitch. I suggest starting just inside these lines and growing outward once the exact position of the blade in the cuttout can be located. The two lines leading from the rear edge of the spinner to the blade opening should be followed exactly since this section is needed to back-fill behind the prop.

Subject: [LML] Spinner cutout template for L–360

Does anyone know where I can get a template for the spinner cutout of a Hartzell 68" constant speed prop? This is for the L360 series.

I called Lancair and they said they never had any templates and the cutout is up to me. Hard to believe that's really the case but that is what Ross in builder assist told me today. Considering the cost of a new spinner, which Lancair doesn't even sell anymore, I am reluctant to start hacking away on the spinner in the unrealistic hope that I might just get it right on my first attempt.

Can I just use a CS prop spinner template from Van's? That's at least better than an outright guess....... Or maybe not.

How did you L360 fliers do your cutout?

Thanks

Doug
