From: Matt Brock Interesting Keith. It is surprising how many different combinations of skins, spars and fuel tanks there are in the 'fleet'! It would seem the biggest issue overall is the ethanol problem. There must be a product out there that is 100% suitable for sealing fiberglass tanks against ethanol. I know that boat manufacturers are now claiming to be building 100% ethanol resistant fiberglass tanks. Google Hightide Marine for example. I have asked them if they will share details of the resin system they use. Regards, Matt Brock. +971507052665.

The degree of dissolution is a function of the specific materials involved and the solvent's chemical activity, concentration and time and temp. For polymers like epoxies, the degree of cross-linking determines the tendency to dissolve and if it is a thermoset, the cross-linking density is higher so dissolution is slower, measured in years of exposure. The higher the initial cure temp, the better solvent resistance. A 350F cured epoxy resin will be considered uneffected by gasoline with ethanol for years of exposure but a room temp curing epoxy adhesive will begin the degradation process quicker. When you have a structure that requires room temp construction (Pulsar kits), those cured materials have a lower chemical resistance to direct solvent exposure. The easiest remedy is to put a sacrificial coating of higher solvent resistance material over the weaker base to keep the solvent off the more susceptible material, and that's what the Jeffco novolac does. Given years of constant exposure, that too will gradually degrade and will need recoating to provide a new, resistant surface. So this problem is systemic when fuels with solvent are exposed to epoxies and you just coat the surfaces periodically to keep the underlying structure sound. It's like painting a wood home every ten years. Or you construct the tank from a metallic material that is uneffected by solvent. It's too late to redesign and construct metal tanks in flying Pulsar planes, so the protective coating, inspected and maintained, will keep the wing structure from degrading.

Would like to hear from those owners. It's really too ba d we do not have the the factory documentation for things like this. Obviously, if there are no ribs then bladders will work well in the leading edge. I remember talking to a vendor at Oshkosh several years ago about bladders for another airplane. I would still follow the sealing with Jeffco and PRC. One person has suggested using 1.7 oz. glass in the Jeffco to reduce the possibility of cracking. When I talked to the guy at Oshkosh, he was wanting a mold or tank to work with to make the bladders. I think if we could give him the end ribs and length, he could take it from there.

How much are you asking for a lower cowl? I am building with a normal style focal engine mount so the cowl will not be structural. Does anyone have a mold for the upper also? I need both.

These parts can be done in one of two ways, either prepreg or resin infused. The one I'm doing for this plane will be resin infused. I'm waiting on pricing for the foam from another company, which is the least cost of the expenses. Note that the return flanges can be removed for those not wanting to do the triangular return flange of the cowl and opting for a standard joggle for using camlocks. The joggle itself would have to be a layup performed against the upper cowl. -------- Kris Anderson, Owner Precision Composites Technologies, LLC 509-521-7564 www.precomptech.com Read this topic online here: http://forums.matronics.com/viewtopic.php?p=417959#417959 ________________________________ Message 13 ____________________________________ Time: 03:47:14 PM PST US Subject: Pulsar-List: Re: Lower Cowl Mold From: "PreCompTech" There was also initial discussion of using the existing upper cowl to make a plug and mold, but we'd rather not mess with the finished paint already on it per the customer. If anyone has one that we could utilize that's in perfect shape and would like to offer its use as a plug and returned afterward, we could do this. -------- Kris Anderson, Owner Precision Composites Technologies, LLC 509-521-7564 www.precomptech.com Read this topic online here: http://forums.matronics.com/viewtopic.php?p=417961#417961 ________________________________ Message 14 ____________________________________ Time: 07:07:22 PM PST US From: Brian Anderson Subject: Pulsar-List: 912 fuel pump The recent Rotax SB on swapping out the fuel pump got me thinking. While my engine serial number was not one included in this SB it is a pretty old engine. It=92s been flying now for 13 years, although only just 500 hours. It still had the original fuel pump. I decided that it was time to change to the new design. Fitting the new one was easy, although because it is slightly different in shape from the original, I had to relieve a little area inside the cowling to provide clearance. I suspect my engine is actually mounted perhaps 1/4" further forward than necessary, making the fuel pump clearance to the front of the cowling very minimal. Mmm - - note to myself, next time I have the engine out make two new engine mounts, i.e. the angle aluminium pieces bolted directly to the engine sump, and shift the whole engine back just a smidgen. Out of curiosity I cut the old fuel pump open to check the state of the diaphram. It still looks pretty good. There is clearly some discolouration of the diaphragm, but it is still perfectly flexible. Of course I can=92t compare it to a new one, but it still looked to have a deal of life left in it. Here=92s a pic of the disassembled unit.
