Posted: Sat Nov 21, 2009 7:44 am Post subject: side baffles side

I am leaning toward using a single piece side baffle on both sides

versus the 3 piece that comes with the VAN's kit. Any one see any issues

with doing so? I know the industry standard is three (one per

cylinder)and I gather there is a reason for that (movement of cylinders)

so not sure if having a single piece will cause any issues..

Thanks!

Tim, how is it more work to do,,,,  Only 7 screws holding it on the side, a few in fromt, and a few in back.  And the ones in the front and back are there no matter how many pieces the baffle is made from....  and also, help me out here.... is removing a cylinder something that I'm going to have to do very often?

 Thanks, Don McDonald

It's enough work getting the front & back assemblies on as it is without having them tied together.  Why add the fabrication work of making it all 1 piece?

Thank you for the reply.

While I am flying however, would there be any issue with a single sided

baffle. I am thinking does the baffle need to move at all, is there a

heat expansion issue that having three separate pieces would allow for

expansion and contraction, etc..



Thanks!

You'll wind up with three pieces sooner or later anyway.  Starting out 

with three pieces means you get to pick where the cracks go.

IIRC, TCM lifters come out without splitting the case, however if the 

cam is damaged the engine will have to come out entirely to send back to 

TCM for repair. On new Lycoming engines you should not have any cam or 

lifter distress with the roller cam, but if you do, it is still pull the 

engine and tear it down, not a cylinder removal. Only ring, piston, 

valve, and piston pin plug problems are likely to cause a cylinder 

removal by itself.

Jesse, because I built a plenum, I also built the side panels so I could simply screw/bolt the plenim directly to the top of the side baffles.  It's all on cadcam and we just run it out to the shop where it gets punched out just like Van's does... then over to the brake to put a 90 degree 3/4" lip on the top....  so it's already setup.... I'm going to make Pascal a set, and he/we were just trying to find out if there were any additional issues.  

 Linn, as to your statement about them ending up in 3 pieces anyway.... I use a floating system whereas the screws tighten down on stainless shims, thicker than the baffles, thereby letting the aluminum baffle float.  So far 90 hours, no issues. 

 Thanks guys, Don

Well, I was hoping to avoid admitting that I 'had a better idea' when I 

rebuilt my baffles on my Pitts.  I didn't want to rivet the plates that 

capture the adjacent part .... so did it in one piece.  I bolted the 

single part on .... and about 1 year on the new part .... it started to 

crack.  Stop-drilled the crack didn't keep it from migrating.  Over 

about 4 years .... I had 6 pieces .... with the capture plates riveted 

on. When I got cracking from the mounting holes I rebuilt with 3 pieces. 

  Maybe having them float would have prevented the cracking.

 punched out just like Van's does... then over to the brake to put a 90 

 degree 3/4" lip on the top....  so it's already setup.... I'm going to 

 make Pascal a set, and he/we were just trying to find out if there were 

 any additional issues.  

 Linn, as to your statement about them ending up in 3 pieces anyway.... I 

 use a floating system whereas the screws tighten down on stainless 

 shims, thicker than the baffles, thereby letting the aluminum baffle 

 float.  So far 90 hours, no issues. 

 Thanks guys, Don

Thanks Linn for the input.... that's what Pascal and I were looking for....  I am hoping that by being able to float on the screws, it will avoid the cracking issue.
