4 Nov 05 - Engine Arrives, Working on the Brakes


When I talked to the Mattituck folks last week, the engine was on its way. I called the shipping company yesterday, and they said it would be here Thursday morning.

I think this is the last time for this project that it's necessary to have a big truck in the driveway.

Well, that's enough fun for now. Time to go back to work.

Okay, tonight: we're working on the brakes and NACA vents. Let's see how far we get:

Center brace has been riveted in. This is a pain, as there's not a way (that I could find out) to squeeze those. You'll have to get in with an offset rivet set.

Left NACA vent RTV'ed and clecoed in. We've got some backing plates that we'll rivet on after the RTV has set up nicely.

Whoops! Went to put the other NACA vent in and discovered it was cracked. (Really. It just doesn't show up too well, but there's a crack running towards the hole.) Simpler to just replace the part before it's on the plane, so this piece isn't going on until the new one gets here.

Starting the brakes - these are the straightforward lines to get in there, as they just screw on. The rest of the lines are the high-pressure plastic lines that look like they may be more of an adventure to attach.

We're going with dual brakes, so here are the fittings for the right seat. For what it's worth, we used Bakerseal on all these fittings on both sides.

Interesting observation: we're using Bakerseal for this, and on other connections we are using Fuel Lube. Fuel Lube (as the name may suggest) can be used on fuel lines and oil lines, and Bakerseal can be used on brake lines and also - like Fuel Lube - on oil lines. I've heard various opinions on which one is better from various RV builders. However - and this is important to know - a big difference between the two products is that Bakerseal will set up and actually harden, and Fuel Lube will never do that.

Perhaps an extrapolation of this (and this part is just me guessing, folks) is that it's not a good idea to re-tighten or re-loosen fittings that have Bakerseal in there unless you're going to take it all the way out and put more (non-dried) Bakerseal in there. With Fuel lube, you won't have that problem. On the other hand, you will have it smear on your hand if you touch it accidentally, even if you put it on a few days (or weeks) ago. That won't happen with Bakerseal.

More stuff on the brakes tomorrow.
