Here is my take on it.
1.The problem with trying to fire one plug with two sources is that the
odds of ever
getting both systems to fire at the EXACT same time is more or less impossible,
especially for all four plugs. If they don't fire at the same time the high
voltage
will follow back down the none energized plug wire instead of firing the plug.
2. The other thing to remember is that most likely a misfire will be caused
by a fouled plug which this will do nothing for.
3. I here there are twin plug heads available for model A's.
4. I don't understand your comment about the "former starter hole" being
taken up by a oil filter. I was sure that the starter mounted to the bell
housing
adapter that bolted to the block which you certainly don't want or need on a
airplane.

Dear 'A' Ford Engine Gurus,
On my ('31) Ford I am currently using a single magneto per The Plans.
However, I would like to add a second ignition source (magneto or battery)
and wire both systems to one set of plugs. I have the engine's (former)
starter location taken up by an oil filter, so that type of conversion is
out. I guess that I will be adding something in the original distributor
hole or . . . . ? Ideas Please! I am looking for some sage advice about
what would be some good equipment choices and maybe even sources for same.
Are there any known problems with using two ignition systems with one set of
plugs?
Thanks,
Larry Prange

Would you consider springing for a dual ignition head? I believe that if
you'll visit [www.secretsofspeed.com] you will find them....Carl

Interesting, of all the tail feather pictures I have seen on the net none of
them have had wood strips glued between all the gussets. Has anyone else had
to do this?
What I am trying to confirm is if the 2 8" x 1" x 3/16" plywood pieces glued
to the center of the horizontal stab go on both the bottom and the top.
I'm not sure if I read your problem right? But you
do put the plywood gussets on top, but if you use Poly
Fiber like I did, you have to cut strips of wood to go
around the stabilizer to fill in the gaps between
plywood gussets, as Poly Fiber dacron heat shrink
covering, needs a constant perimeter level piece of
wood to glue to, so when you shrink it, it shrinks
evenly. If you have a gap on the perimeter your
dacron will sag in the gap without a surface to glue
to and shrink distorted. I learned the hard way!

I filled the spaces between the gussets with spruce and sanded to shape.
