| Subject: | What's best way to check grap parts for voids? |
I just finished doing battle with my instrument module taking out about 1/2" warp
of the 3/4" warp that tapered from middle to the right side (right side being
the worst).
I was careful heating till it became slightly soft then clamped module flat. After
leaving over night clamped flat I floxed on plywood and 2 BID over plywood
then clamped that flat overnight. Nice fit to firewall now and flat/ stiff.
However a whole bunch of blisters occurred on the gray gel-coat ranging from 1/8"
to 1/16" in diameter after I heated it. Upon cutting out blisters observation
is everyone of the blisters has a void under it exposing shiny polyester resin,
some of the voids quite deep and the gelcoat quite thin. I am afraid especial
on cowl (perhaps doors too) after final paint once heated, blistering may
occur.
Any ideas best way to identify any voids on gray gelcoated parts?
I picked up my kit 04-2003 Kit # A265.
Thx.

Hi Ron,
Providing you have a reasonably quiet workplace (and a reasonably
good hearing too), tapping the area in question with a coin. you
should quickly hear the difference in sound...it=C2=B4s like ultrasound
inspection without the ultra:-)
In spite of having been inactive on the building front for far too
long, I want to thank you for your ceaseless publishing of
your trials and errors!
Alex, kit 529

| Subject: | oil pressure switch for engine hour meter |
Has anyone in UK fitted an oil-pressure switch to control when an
engine hours meter runs? If so, where did you get it?
A discussion with Skydrive indicates that the obvious place to mount
it is in place of part number 641733, the 10mm x 1mm plug screw which
covers the port on the oil pump that would feed a hydraulic governor.
However, Skydrive are not sure that it will be easy to find an oil
pressure switch with that thread.
I have spotted one on an Australian supplier's website but can't find
anything similar in UK.
It's also important to note that what I want is a "normally-open"
switch - that is the opposite of the usual type which is
"normally-closed" and opens with increasing pressure to extinguish
the oil-pressure warning light.
I'd like to avoid the need to turn up an adaptor for a BSP or NPT
thread switch.
regards
Rowland

Hi Rowland
If you are fitting a constant speed propeller then using Mark Burton's constant
speed controller will give you total engine time,
Or alternately if you have a vacuum system fitted a simple vac switch will work, also there is a two terminal VDO unit http://www.coolairvw.co.uk/ca/mia/d/vdo+oil+pressure+gauge+sender+twin+terminal/pid/6554640?afid=88888
that would work for you,
Ivor

| Subject: | Rotax cooling plenum |
Hi folks,
I have an original Rotax cooling plenum that I am not going to use that I
wanted to offer to the forum before I put it on eBay. It isn't new, but is
in quite good shape. I paid about $150.00 for and would like to get same
for it.
Please contact me off list if your interested.
