Title: Spinner for clockwise prop?
Post by: Randy Powell on May 26, 2014, 05:40:37 PM

So, I know I can just hog out an existing spinner to fit a clockwise prop. I'm using a Randy Smith "Veco" type spinner. Is someone making a clockwise spinner of this type? I've looked at the Tru-turn spinners and they are OK, but not what I really wanted.

Randy,
What diameter are you looking for?  Chris and I got some Brodak spinners that were uncut and Mike Haverly set up his milling machine to cut slots for the prop and for cooling.
They work great.

Hi Alan,

2" is what I'm looking for. I suppose I could do the same.

Hey Randy, watch Sparky's videos and make your own or get one from him.

Hi Randy,

I am pretty sure you can get uncut cones from Randy Smith.

I am reading that several sources sell uncut spinner cones.  The question is how do I accurately cut the slots?  All I have is a Dremal tool and other hand tools.

You need a milling machine with a dividing head and someone who know how to use them.  The set up takes longer than the actual cutting.  I would think any competent machinist could accomplish the task.  Actually, laying out the cuts and cutting with a Dremel tool and a file is not as hard as you think.  

    The most accurate way is with a four or five axis CNC mill or turning center.  That's how things are done on a bigger scale.  It would take a pretty big run to make any money and why Tru-Turn charges what seems like a large amount of money for there spinners.  They have to make a living!  The same is true for a sign shop and their charges for a paint mask.  Material is inexpensive but equipment and manpower can add up.  We are lucky to have vendors willing to take this stuff on for a minimal charge.  

    I am not a vendor.

A quick warning.  Make sure the collet in the dividing head is good and tight.  Otherwise you'll need to paint your spinner when it's done.

I have a different idea of how to mount up the spinner for the mill. We'll see how that works when I try it on an old, dinged spinner. If it works OK, then I will get a couple of Brodak spinners and we will see what we will see.
