ECI EXP cylinder baffles - Page 9

theduff · #81 09-13-2018, 02:54 PM

As The ECI links are defunct from the earlier posts I?m wondering if Continental supplies the inter-cylinder baffle assemblies for the taper fin barrels. If anybody has used them ( if they exist ) how well did they fit ? Any help is appreciated.

I think they fit perfectly.

The guy to ask this question of would be James Ball at Titan "a.k.a." E.C.I., Conty. The good guys from San Antonio have moved to Al.
Hope this helps. Yours, R.E.A. III # 80888

David,

I think I have the ECi baffle mod file at home on my computer. PM me and I?ll send it to you tomorrow if you want it. I did not end up using their solution. I ended up wrapping the lower cylinder fins in RTV impregnated fiberglass (as several other VAFers have done) and using the existing baffles essentially just to hold the cylinder wraps in place. The only other ?seal? I had to add was at the upper interface between the existing baffles and the wraps to make sure all of the cooling air is directed between the wraps and the fins (and not leaking around the outside surface of the wraps).

There is another solution (I believe in this thread) where a builder fabricated baffle segments that would fit the tapered sections, then cut off the existing baffle segments and riveted on the new ones. Very elegant, but the cylinder wrap method looked easier and just as effective. I did use the Drawing the other builder posted as part of his solution as a cutout template for the cylinder wraps.

Hi Jason,

It would be interesting to see some pictures of how you did your cylinder wraps. Can you please post some pictures or email them directly to me.

Thanks,
Mark

I appreciate the templates produced for this solution....but...it seems several are backward.
here:http://www.prettybits.com/files...nental-ECi.pdf
Was very careful following directions. #3 is a good example. The double bend makes the taper go the wrong direction. Similar problem on #2. Further proof are pics earlier in this thread from a hand drawn templates and produced parts that appear the correct/ opposite orientation. Haven?t fully checked the other two yet. I?ll be better at it second time around. It could be the wording, ?this side toward cylinder? on the templates causing the issue.

Anyone else run into this?

You are correct. I had to re-do some because they were backwards!

Interesting... I didn't run into this issue since, obviously, I built mine from my hand drawn versions.

If Bill sees this, maybe he can correct the PDF file. I can then update the hosted version on my website.

Dang, good help is hard to find!

I will correct them and forward them to you once I correct them.
