FW: HW-8

[Mike Besemer (KG8L)]

Hmmm, at the risk of offending any of the true purists, I'd have to say that
I'd probably be interested in one of these jewels!  My poor old HW-8 is far
from pristine anyway, so the improvement garnered from a more reliable
tuning cap would probably be worth 'desecrating' the rig for!  Popping the
cover off of mine revealed that the current tuning cap is mounted on a 'U'
bracket about 3/4 of an inch deep and the vernier drive is mounted off of
the inside of the chassis about 1/4".  If the shaft on the new cap is 1/2
longer and you removed the existing drive, chances are the shaft will be too
short! (assuming mounting it on the original 'U' bracket.  If you pulled the
vernier and the 'U' bracket out, you could use standoffs to adjust the depth
to the correct dimension for the knob to fit.  I'm not sure yet how to
attach the dial...I'm sure some ham ingenuity could come up with a solution.
Sorry I can't be very definitive here, but I think that the extra shaft
length could be compensated for.  Keep us informed...I'm tired of my cap
falling apart!

Hello:
Still thinking about having a batch of 26-152 vfo capacitors made for
HW-8's.
An option they gave me was to add an in-shaft vernier drive. This also
provides a slip-clutch to prevent the inherent problem in the 26-152, that
of the rotor plates falling off the shaft due to overtorque at
end-of-rotation.
I would like some opinions regarding this...the shaft will be 1/2" longer
with the vernier.
I am well aware that proposed modifications can make some folks need a
change of shorts, but considering the weakness/flaw in the capacitor
installation and the cost of a new one ($15-20), I'd like to explore an
'improvement'.
1)      What are the consequences of a longer shaft? Does the knob stick out the
front of          the radio too far, or is it impossible to fit, or could
the cap be moved back on the chassis 1/2"?
2)      Is there currently a vernier in the HW-8, and would a second "throw off"
the dial readout?

Thanks
