Baffling Replacement

[Davidv]

After seeing a lot of tearing and unsecured rubber baffling (the staples are coming out), I think it’s time to replace.  Has anyone replaced theirs? Any recommendations on best kits?

I replaced mine.  I purchased the raw materials and converted from staples to cherry rivets.  An A&P/AI inspected and signed off.  It too about 10 hours of labor...  I used the old baffles as templates to cure the new ones... As soon as I find a photo I'll post one.  If you want a materials list, let me know

Thanks Alex! Yes a material list would be great if not too much trouble.  Did it improve temps at all for you?

I think its @GEE-BEE that sells baffle kits. They look pretty nice. @ilovecornfields had a write up a while ago of the installation

 If i linked the wrong accounts sorry. Its been a minute.

Good memory! Love my baffles. You ever get to the avionics shop?

Had it done at Expert Aircraft at F70. Great guys!

David I replaced a few pieces like Alex mentioned, I plan on doing more in the summer, I just traced the original and replaced. Definitely helped the cht’s

I put a GeeBee baffle kit on my Bravo about 3 years ago, and it works great, Lowered the temps. Wasn’t to bad to install, Took about 10 hours to remove the old and install the new, could be done faster I guess , I’m  just very meticulous though.

Thanks, did you also get yours from @GEE-BEE?

I got mine from @GEE-BEE

Much better material than the rolls that you buy - no comparison. If something takes 10 hours to do, don't spend that much time installing a lesser product,  just pay the extra for the better product and have it last twice as long,

How exactly is it better? Last I checked it wasn’t FAA approved. Has this changed?

That was 19 years ago. This has been discussed before on Mooneyspace.

The vastly superior material is sold with certifications and is replaced as an owner produced part. Cessna and Beechcraft use it in their new production airplanes. My IA who used to be Mooney's Service Director wouldn't let me install the material that you buy from Spruce that comes on a roll. He showed me a sample of the good stuff and it's pretty easy to see which keep its shape and will hold up better. I've put it in an Encore and a Bravo and have been very happy with the results. Spruce also sells the kits produced by @GEE-BEE.

The vastly superior material

So you are confirming it’s FAA approved? And how is one silicone baffle material “vastly superior” than another? I understand Gee-Bee will cut it to fit and that’s great but what else?

I’m comparing this, which is fiberglass reinforced to give it a great combination of strength and flexibility, to the baffle material which I had that is not fiberglass reinforced.

What additionally makes the GEE-BEE kit worth the money is that it is die-cut so you are not trying to trace the original seals and doing a hack job, while at the same time saving the labor costs of doing so. The result is a very professional job that you can be proud of.

Peter,

Are you refreshing your engine bay?

0BU is approaching perfection... there aren’t many areas left untouched, available to be improved...  

Best regards,

Sorry for the delay in listing the promised materials.  Here's what I used from Aircraft Spruce below.  In addition, I used a new high quality drill bit to drill the holes for the rivets.  Most of the rivets were backed with a baffle seal washer to create enough thickness of material to properly compress the rivet, if that makes sense.  I know you can buy kits and so forth but I really enjoy this sort of thing.  I'll post some photos in a bit....

Other tips:

1.  Buy a silver paint pen from a hobby store and number the old baffle seals in order clockwise as you remove them.  This will make it easier to keep them in order when you cut them and place the new ones.  

2.   I used tin snips to cut the baffle seal material that I already had on hand.  These are easily found at one of the hardware stores.

3.  I used a portable vacuum to catch the shavings from the drill holes for the new rivets.
