Fw: OS 160 soft mount question

[Rcmaster199 at aol.com]

McMaster Carr has a variety of these in their catalog. You guys might want to 
try that source.

I have used the 1"x3/4" rubber isolators with the 1/4-20 stud, in a 1/3rd 
scale job, isolating a BME102cc twin and that worked pretty well. Five of these 
large isolators were enough for the large gassie. Two or three of same would 
work fine for the 25-30 cc engines we run in Pattern. The large isolators are 
about 1 oz each but have at least 4X the shear strength of the 5/8" isolators 
with the 8-32 stud.

I tried the setup on a 1.45 size engine using five lord isolators and a 
backplate to mount to the engine. It required a nosering as engine movement was 
significant. The lord mounts tended to pull apart. The lord mounts are available 
at some hardware stores.

Rich,

Unfortunately, this is where CRS disease comes in--I'll be darned if I can 
remember. Seems like we got the back plates one place and the mounts 
another(this was the '80s).  All the Lord mounts are, are rubber isolators of varying 
durometers with a stud on one side and a plate to accept a screw on the other all 
molded in--I think Dave Brown(or someone) uses them on the pipe mounts.  
Again, it seems like Sullivan bought the rights to the back plate mounting--But 
there's really no reason you couldn't use the standard mounts with them and a 
nose ring.  As I think about it with the larger fuses, there would be adequate 
space to spread them out to eliminate the nose ring altogether as we did back 
then.  The engine DID move around a bit--but didn't seem to affect it in the 
air--or there is the VERY strong possibility I wasn't good enough to notice..... 
 Seems like they were a teensy bit tricky when installing the firewall.  I've 
still got one of Frack's IVs, a Summit 3, and a Goldberg Ultimate with that 
set-up with no nose rings;all piped OS REs or Hannos and they are all still 
quiet, solid airplanes.

Hi Richard, 

    Would you let me know where you bought the Lord mounts?



Thanks, Rich
