Quich question to balancing:

Though your list is not specifically pointed to=20 balancing.

For a dynamic balance job DO YOU or DO YOU = NOT=20 include the weight of the apex-seals?

Apparently they should not bear on the = rotor/excenter of=20 the shaft, as the rotorhousing carries their weight at all = times.

Am I missing something?

Subject: [FlyRotary] = Weights

Rusty,

Here's some very accurate weights for = your=20 records-

Apex corner seals x6 =3D = 19grams

Apex corner seal springs x 6 =3D = 1=20 gram

Side seal springs x6 =3D1 = gram

Side seals x6 =3D = 25grams

Oil seal springs x4 =3D 10 = grams

Oil seal retainers( metal) x4 = =3D 92=20 grams

Oil 'O' rings x4 =3D 16 = grams

Total of 164 grams ( 5.784936 = oz)

Weighed all together 164 grams ( as a = check for=20 accuracy)

RX8 Rotor 9.3346lbs( 4243 = grams)

I just can't see how you get 10 lb 9 = oz rotor=20 weight comparing these weights, even though the RX7 rotors are a = tad=20 heavier!

BTW Tracy's apex seals are 30 = grams.

George ( down=20 under)
