And speaking of the spinner cutout where the root of the prop blade passes through, below is the blade cutout template for the Hartzell BA props (C2YR/-7496 & -7497):

Have you rotated the propeller blades through their entire range and confirmed proper clearance?
Blade rotation requires quite a bit more gap than most people would think. The marked opening are for the propeller recommended by Van's though. If using a different propeller it is probably a good idea to start a bit small and adjust for what you have.

I might ask this in a separate thread, but I will start here. I have a question about the Spinner Gap Filler. This is an observation and question.
So I followed the plans (I think).
44-03 Step 1: Use a hacksaw......Position the cuts along the inside edge of the marked line.
Well I did this, but the marked line on my spinner was done with a very thick marker, while in the plans it clearly shows the line as something made with a sharp point pen. Anyway, after sanding to get the spinner to fit around the prop, the gap filler is 5/64" (3-4 mm) narrower than the spinner. If you look at Figure 3 on 44-05, you will see that the gap filler might have a 1/8" gap on either side, maybe less. Mine will be a lot more. I am not sure if I should line the gap filler so that it has an equal gap on both sides or line it up to one side, then try to span the gap somehow with fiber glass. My fiberglass skills are not that good.
I think that the plans should be changed to state, cut to the inside of the outside edge of the black mark line. I had to sand to completely get rid of the black line to get the spinner to fit. Currently, the spinner just clears the prop (I have not rotate prop yet). Once I get 1/8" clear for the prop in the "neutral position", the gap filler will be off by almost 1/2" if I drop the lines straight back to the back spinner plate. I guess I can not make the line straight back. Not sure how this will work out at this point. Many of you might say: "you should have know to cut to the outside edge of the black marked line."
Does any one know if Harzel (or any one) sell gap fillers that are the correct size? I know that this is a dumb question.
I think that the easier thing would be to do is to buy a new spinner and cut out the gap fillers from the new one to the correct position, then use those and keep the extra spinner just in sase i need it as a later date.
Wonder how much spinner costs.

Just make one out of .063 aluminum. It will hold up better anyway.

I used the spinner itself as a form to make a new gap filler piece. Wax up the outside and make a 4-ply layup on the edge away from the gap. When you pop it off you can trim to fit perfectly. Packing tape works too and keeps from having to worry about epoxy getting over the edge. After I made the piece I sanded and did a small layup on the back to make an edge that goes under the spinner to take a nut plate and the screw so that the gap filler fits in without another reinforcing piece.

JDR_BTR--
My fiberglass skills are up to the task that you suggest. I guess I will trim the spinner to the 1/8" clearance first and then build the new part.
Now I have a reason to use some of that huge excess of fiber that I purchased.
thanks
ken

Tim--
So I assume that the difference in thickness does not matter in this case and that after painting, it would not be visible anyway.
True?

I just did mine per plans. There's a small gap but I really don't notice or think about it much.

You can measure the fiberglass if you want and use a different thickness of aluminum if you wish, such as .050 or whatever matches. I used .063 on both airplanes.
The big thing to remember is come paint time, you'll want to paint whatever you fill that part with, along with the spinner. I forgot that on my RV-14. I had the part alodined gold, so it still looks good, and you'd never notice if you weren't looking for it, but it worked out fine.
