Guys,
anyone reccommend a place that will make a custom spun Spinner? I beleive there is agood one in Germany but can not locate them. I'm wanting to get one done for a 1:4.6 scale Mk IX Spitfire and those that know Spits understand that get the spinner wrong and model looks off so scale fidelity is amust.

thanks in advance

cheers
Peter

Do a google search for Gene Barton Machining. He does great custom work. Mitch

I have gotten away from machinists and their relatively limited spinner stock by laying up my own plug and making a fiberglass spinner...advantages include making any spinner shape you desire...much less money and you can use the plug to make a flying and static spinner. FG spinners are relatively easy to balance and tough as nails...try making your plug out of foam and epoxy...it is alot easier than one may think...best of luck

La7flyer,
How do you attach the spinner to the back plate. Have been interested in trying to make my own spinner for awhile. Wondering about back plate attachment and balancing.

Just like the real ones, the spinner fits over the back plate and is attached with metal screws...I use 6 screws...2 on either side of each prop blade opening and 2 spaced equidistant......between the 2 blade openings...I have used this method for the past several models and have never had a problem....

Edwin,

I read about this a few years ago and tried it. True to scale, balsa spinner. The technique worked perfectly.

Take a side view drawing of your aircraft, phototocopy it.
Enlarge it until the spinner is the correct diameter
Use the enlargement as a plan.
Decide on how thick you want your wood to be, and yes you can use balsa.
draw vertical lines on your plan at that thickness
measure the diameter of each disk,
draw them on the wood,
cut them out, these will be stacked like the layers of a wedding cake
if you used a compass, the pinhole marks the center of each disk, enlarge the center holes so you can fit a dowel or treaded rod about halfway into your spinner.
Epoxy the disks together, aligh but do not glue in the dowel.
let dry
insert the dowel
Mount it in a drill press or lathe, spin it at the highest speed
Shape it with a piece of sandpaper.
Trace the one half of the shape of the spinner onto a piece of cardboard and use it as a profile gage while sanding.
coat the whole thing with thinned epoxy (1st coat only), let dry
mount and sand on the drill press
re-coat with epoxy (20 minute epoxy)
mount and sand
recoat (20 minute epoxy)
mount and sand
recoat (20 minute epoxy)

The prop is fitted into the back of the spinner, no back plate needed; take your time with the dremmel tool and it will fit like a glove.
A smaller hole is drilled through to the tip of the spinner and the spinner is attached just like a plastic spinner with a center screw would be.

The spinner is lightweight, is perfectly balanced and is flyable. It can be painted and thanks to several coats of epoxy, it holds up well to electric starter cones. Best of all it is has a scale shape.

Good luck
