Dale:
WAY TOO MUCH WORK!
Vinod... This is what you do...
Just get a 4-40 threaded rod - - A few 4-40 Locking Nuts [NOT ELASTIC STOP
NUTS // NYLON LOCK NUTS <--- NOT!]
Cut the rod 1 1/2" longer than the spacing between the baffle flaps.
Install a Lock Nut at each end and tighten down just enough to hold the
shape of the baffle curve next to the cylinders.
THAT IS ALL - YOU ARE DONE!
But ... Tthere is always a BUT!
The part that FAILS is the HOLE in the ALUMINUM Baffle.
To prevent this - - Well, that is a bit more work.
Install a BRASS GROMMET in the hole. Peen over the part that goes through
to hole in in and lock the position. The HARD parts about this are:
1 - Finding or making the Brass Grommet.
2 - Peening it.... The baffling usually has to be removed. There are a few
tricks with a rivet squeezing tool BUT you would need a rivet squeezing tool
and die.
Sorry I can't make this part as easy as the first. Hope you have baffles
that have the hole?

It is a bit of light work ....sounds more than it is..
BUT, I don't have any problems with the hole failing in the aluminum baff
le after 6 years. And, there is no need to remove the baffle....

Another solution I used....
Cut the heads off from four 1 inch 4-40 screws. Peen a flat o
n the cut end of the screws. Drill a hole in the flat for safety wire. Conn
ected each end of pre-measured length of safety wire to a screw. Insert a s
crew, with an adjustment nut already on screw, into hole in each baffle. In
stall all metal lock nut on end of each screw. Adjust for proper length and
tighten nuts.
