Not sure Guessing need crush plate or different inner plate for wooden prop. I can measure how far inner disc goes down in spinner. Thickest of prop that can be used. The spinner is 12inches Dia and 13inch long.

I have 1 now for a metal prop the bulkhead is pretty thick. Using a wood prop and makes the spinner sit off the back plate by about .300. I can't see in the pics whether they are the same.

I have a B-N3 on my airplane and the wood and metal Sensench props (I have both) are the same thickness. The wood blades require a larger cut out. Check out this Acro Sport Newsletter.Vol4.60.pdf

My Prince is thicker than the Sensenich by about a 1/4".
I will likely have to make my own.
If it's for a wood it would kill 2 birds for me.
Thanks

My installation required a .200" spacer between the prop and front bulkhead to make the front bulkhead "time out" with the seating on the rear.

These came with my project. I believe they were intended for the Prince 76x62 wood prop that came with it. Not sure if I need the prop extension for mine or not. I've got a CF Ultimate spinner on the way for my project.

I don't know jack about prop's, etc. Can you use a prop extension if you plan to fly aerobatics? I have an O-360 with a solid flange aerobatic crank. Not sure if I'll need a prop extension with the Ultimate cowl... Not at that point yet.

Kelvin, the one I have is like the second from the left in the foreground. I believe the one I need is the far left.
Most everybody using the Wolf cowl is using an extension. Mine will have one as well. We'll find out how much it'll take;)

There are various bulkheads available for the BN3 depending on the prop. Years ago, I re-spun the aft bulkheads to make them a forward facing flange to give cowl clearance without a spacer. Then I asked ACS to make them and they did, you had to request "forward facing flange on the aft bulkhead". You had to notch the flange around the prop.

I was recently advised by ACS they were no longer carrying the BN series of spinners. The guy that supplied them passed away. Maybe someone will take up where left off ? I bought a Catto for my project (there very close to me). I have a BN3 set up for a metal Sensenich if someone really needs one. I needed different spacing for the MT I bought.

Crap! Going to have to waste more time sourcing stuff. Their recent catalog omitted other stuff I use regularly. Guess they are slowly getting out of homebuilts, maybe their plan is to compete with Wallymart.

Is this spinner still available? If so, I would like to purchase.

Sorry, I missed that there was a second one floating around. Is it cut or drilled yet? I already have a back plate fitted, need a viable front plate and spinner. 3-3/8" hub, McCauley prop. Thanks.
