I purchased a 12" UHS spinner from ACS for my 601xl/corvair.  Has anyone else used these.  I was surprised to see that it comes with only a single bulk head for the front of the prop.  How much of a concern is this?  What are others using?

Dan,

 

 I used the spinner from Van's that WW recommends.  It has a bulkhead behind the prop and one in front of the prop.  It was fairly easy to install and runs true.  I can't imagine how a spinner would work with only one bulkhead.

I don't know where they get them, but the AMD spinner uses a single bulkhead

at the front of the prop as well.

A single bulk head in itself isn't a problem. What may be a problem is if you are going to use the WW nose bowl you are going to have a 1/2" area around the spinner that doesn't match up with the nosebowl. It will produce a slight but probably measurable amount of extra drag.

That's the same spinner that I have.  Haven't flown yet, but it mounts up just fine.  I measured and told ACS the dimensions I needed and it came out perfect for me.

Jay,

My spinner weighs about 2 lb 6 oz.  This "seams" heavy to me.  Did you by chance weigh yours before installing it?

Dan,

 

 No, I didn't weigh it. Van's installation sheet doesn't give weights, either.  I'd guess that the fiberglass cone is from around 1/16" to 3/32" thick. Van's drawing calls for a .063" (1/16") thick filler behind the prop blades. I actually used part of the cut-out for the prop for the fillers. The base of the cone is 13" in diameter and it is 13 1/2" from base to tip.  The bulkheads are .063" 2024-T0 aluminum.  We ('Vairheads) had to get together and come up with a hole pattern to fit the WW hub bolt pattern.  When installing it, I used a laser spot aimed at the tip of the cone to insure the tip wouldn't move. I had the spark plugs out and rotated the prop to make sure of the alignment.

Jay,

Thanks for the info.  At this point knowing the weight might convince me to call the UHS a mistake and order the Van's spinner.  I'm really not very happy with the finish.  There are many imperfections in the surface.  

With 2 bulk heads I assume thickness of the prop is tightly controlled.  My prop is 3 3/4" thick.

I'm a little concerned about what you say about the bolt pattern.  Isn't W. Wynne using SAE1? (6 bolts on 4.375) That's what was on the plans I purchased from him about 5 years ago.  Think I'll go visit the Van's site now.

Dan,

 

 My spinner from Van's had a super finish, right out of the box. It required no finish work, other than making the cut outs for the prop and painting.  I don't know the SAE numbers, but WW's bolt pattern doesn't match Van's. I have a drawing of the bolt pattern we came up with.  Let me now if you want me to send it to you.

Jay,

Thanks for another reply and offer.  No, I won't need the drawing.  I made my own prop hub.  It is SAE1, and the UHS SAE1 bulk head fits it.  At this point I'm seriously leaning toward ordering the Van's spinner, but I can't find definite information on how thick of prop it will take.  The Van's web site just says "thick wooden prop".  I've seen one customer's sight that calls it 3.5" which is too thin, and another that calls it 4" which would work great.   My prop is 3 and 3/4 inches thick and I have a 1/4" thick crush plate.   If someone could report on the weight of the Van's 13" spinner that's help me decide too.

If I were to do "finish" work on this spinner it would involve using some filler to fill in the little scoops and waves that are in it.  Then it'd be out of balance.  So if I use it I'd have to just tell myself it's good enough as is.

Thanks anyway.

Dan

Dan,

 

 Van's instructions show installation for a wood prop, a metal prop and a constant speed prop. My prop is a Warp Drive and it worked just fine. They show different front bulkheads for wood, metal and c/s, all of which bolt to the prop assembly.  As I recall, with mine, the front bulkhead was in front of the prop hub and not attached to it.

Jay,

  

 I also have Van's spinner FP-13 but the rear bulkhead bolt holes do not fit WW hub and the front bulkhead would not fit Warp Drive prop at all.  I emailed WW numerous times inquiring about the front crashplate/bulkhead but he would not reply.  Can you post the bolt hole patterns and how you got the front bulkhead to work?

John,

 

 Here is the drawing and a photo of the rear bulkhead bolt pattern.  You will notice that two of the holes are "enlarged" existing holes.  This is OK since the alignment of the bulkhead is assured by the close fit of the bulkhead center hole to the WW hub and a good fit with the other holes.

 

 Van's apparently has several different forward bulkheads for this spinner.  The one I got sits far enough forward to clear the Warp Drive prop hub. I didn't have to do any modifications to make it fit that way.  I guess the secret is in getting the correct bulkhead.

 

 Let me know if you have questions.

Jay,

Are you saying you don't have the propeller bolts passing through the front bulk head?  Is there anything holding the front bulk head on to the prop?  I don't see any use at all in such an arrangement.  Normally one would use spacers, and long enough bolts to attach both bulkheads to the prop/hub assembly.

As to the drawing,  it looks like you've confirmed that William is using SAE-1.  It appears Vans has drilled the bulkheads for SAE-2 which I believe is 6 bolts on a 4.5" circle. (don't quote me)

Thanks for the post.  Denise may skin me alive but I may be purchasing the Van's spinner.  I still need to find out if there is enough space (I need at least 3 3/4" between bulkheads, and would like to know the weight of the assembly.   One of the list members said he may get those dimensions for me this weekend.  If he does I'll post them here so the group can benefit.

Dan

Jay,

  

 Those are very helpful pictures of rear bulkhead.   I will do as pictured.  My front bulkhead is also small enough to clear (~1" in front of) the Warp Drive prop hub, and I have no idea how to mount it.  Does your front bulkhead mount directly in front of the Warp Drive prop hub?

The spinner that Van's sells will  work just fine if you do some modifications to it. The Hole pattern is  SAE 2 and you can either enlarge the holes in the lower bulkhead or you can  drill new one's using the prop hub as a drill guide. If you use the prop  hub  it will be self aligning with the center hole in the bulk head and  then you can simply drill new holes. This bulkhead is in compression so either  way (enlarging the first set of holes or drilling new one's) will work just  fine. 

  

 As for the top bulkhead you can either continue to try and get the one WW  makes if you ever get an answer from him....... OR you can go to Lowe's and buy  6 1 inch spacers and 6 flat washers and drill the front bulkhead and crush plate  for 1/4 20 screws and that will give you the perfect height for a Warp drive  prop. 

  

 If you are using a wood prop you will need 6 3/4 spacers and 1 washer. I  will post a pic of one I did and you can see it isn't that hard to do. I like  the Van's front bulkhead much better than WW's because it makes the spinner  rigid and WW's can be moved from side to side but if you can't get one  what's the point.

  

 Here are some pics of it  and if you need anything else I will be glad  to answer my email's and help you thru the process.

Jeff,

I'm not sure who you meant this post for but it doesn't answer the question I've posted repeatedly, which is what is the distance between bulkheads?  Obviously you know, or you wouldn't be able to recommend 3/4" spacers for some combination of prop and crush plate that you know about. 

I thought there'd be enough corvair builders on this list using this spinner that someone might know the dimension, but I'll try asking on the RV board.

Thanks for your post anyway.

By the way I've posted a picture of the UHS spinner on my website at:

Hurray!  Gig (William Giacona) came through for me.  The distance is "approximately" 4 1/4".  So my 3-3/4 prop with 1/4" crush plate should fit with 1/4"  (spacers) to spare.   Thank you Gig!
