From: "rparigoris" 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.

From: kaarsberg@terra.com.br 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!

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 -- | Rowland Carson ... that's Rowland with a 'w' ... | http://home.clara.net/rowil/ | Skype, Twitter: rowland_carson Facebook: Rowland Carson | pictures: http://picasaweb.google.com/rowlandcarson ________________________________ Message 4 _____________________________________ Time: 12:37:06 PM PST US From: Subject: Re: Europa-List: oil pressure switch for engine hour meter 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 > Has anyone in UK fitted an oil-pressure switch to control when an > engine hours meter runs?

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.
