We go to some lengths in building our aircraft to ensure that we use fire-resistant materials (or we should do). The fumes from burning fibreglass in a confined space are not conducive to a long and healthy life even if you do manage to get out after inhaling them for a while. Worth considering, I think.

A long time ago, I got a look at some pictures of George Pinneo's plane, and amounst many nice things that I liked about it, I admired the lower panel that he did. By adding that lower panel, plus using a digital engine monitor instead of lot of analog gauges, it really clears up the upper panel area, which then allowed me to have the "map box" too.

I used a sharp drill bit, slightly smaller than the rivet (#23 for the #5 rivets). Use a variable speed drill and keep it slow, otherwise the stainless will ruin your drill bit. Drill just a little deeper than the head, the head may fall off, if not, use the other end of the #23 bit, place it in the drilled hole and rock the head, it should fall off. After you drill the head off, you should be able to punch out the center mandril and then the rest of the rivet. If you have access to the back of the part, you can pull the rivet out with pliers, or use a weighted object with a hole big enough for the back of the rivet to back up the part while you punch the rivet out, to avoid distorting the parts.

My question today is, no matter how hard I tried I could not get every single air bubble out of the line. Is this a "major" issue? Will the bubble eventually work itself out or do I need to get back in there and do whatever it takes to makes sure there is ZERO air in the brake lines? Thanks for any and all help.

What is best is probably evaluated on performance. The brakes should feel positive, not soft or spongy at all. If you have the MC-5s, bubbles are going to get above the cylinders at the reservoir end. You will probably have to recycle a bit of fluid to totally bleed out the lines at the other end where it's most important. This is a two-man job to get it right. Good luck, Larry C. McFarland - 601hds ________________________________ Message 17 ____________________________________ Time: 05:44:04 PM PST US From: IslPilot@aol.com Subject: Re: Zenith-List: Removing Stainless Steel Rivets --> Zenith-List message posted by: IslPilot@aol.com Tom: As a mechanic I have removed similar rivets with a dremel tool with an abrasive cut off wheel. You can carefully shave the head and then punch them out. A drill bit really can wander on the harder materials.

When I would pump brake fluid, an air bubble would actually start forming as I compressed the oil can trigger, that bubble then gets transferred to the brake line. I cannot think of a way to stop this from happening without have a delivery system that is airtight! Is that the case or am I just missing something basic? I tried to keep the fluid level in the oil can high enough so that the probe end would always be in the fluid and not essentially "sucking air" But even when I thought the probe was completely immersed in fluid I would still get an air bubble into the line. One side seems better than the otheer. On the paasenger side there is about a 1/2 inch air bubble in the line. This unfortunately does not count areas that I cannot see because they run through areas that I cannot easily inspect. But on the pilots side brake line there are no visible air bubbles in all easily viewed areas of the brake line path. As a side issue, if someone is using aluminum brake lines which you cannot see through, how would you know if the brake lines had an air bubble in them?

The reservoir has to be higher than the master cylinder. That way no bubble will be introduced. Another solution is a pressure bleeder. George ________________________________ Message 22 ____________________________________ Time: 11:14:16 PM PST US From: "Phil & Michele Miller" Subject: RE: Zenith-List: Brake Bleeding Question --> Zenith-List message posted by: "Phil & Michele Miller" Steve, When I acquired my 701 with Matco cylinders it had a leak on one side where the bleed nipple wasn't fully tightened. There was no fluid in the cylinder or the line and probably very little in the wheel cylinder. I was advised to simply top up the cylinder and pump it repeatedly to get rid of the air (no opening of the wheel cylinder bleed nipple). I was sceptical but tried it anyway and it worked perfectly. Before long I had no air and solid pedal pressure. Obviously I had to keep the cylinder topped up as the air came up and the fluid went down. It's worth a try.
