I just set the 184's up the roof after removing the middle one to see how they look. I like it!. Still need to add the siren speakers after I locate angled mounts.
The skirts need to be trimmed to level up the beacons before you bolt them down. The correct installation will have the top of the lens level to the ground.
Richard, Jerry Jacobsen told me about a method of trimming beacon skirts last month in Flint that sounded good. He uses a compass (the kind you used to draw circles with in geometry class). You should contact him for the specifics as I'm not sure I have the method exactly right at this late hour! Basically you level the light on the roof w/ some blocks or somthing sturdy underneath the beacon, then use the compass to trace the roofline, marking the skirt at the same time. Obviously you need to mark the "uphill" side of the skirt, since that's where you'll cut an ellipse to make it level. Glad you finally found a pair!
Just sent Ed an email asking for advice on how to trim a skirt. Hope to have a check headed in your direction Brady for the pump and hope to be able to pick it up within 30 days or so.
Those twin 184's look great Richard...but then I'm biased because of my Lifeliner. Did you get them off ebay? I noticed that they have the original Federal lenses as well with the stepped top.
As for trimming the skirts, I know that Cliff Bergum has done that in the past as well. I think he used a Dremel tool and went very slow. Not sure how MM did the cutting but I'm sure they used a template as a guide. Perhaps consider making a cardboard template of the base to work at getting the correct angle so that the top of the lense sits level as Brady commented. Once you get the template correct you could use this as a marking guide prior to trimming.
Let us know how you make out.
Rick,
Where did you find gaskets for those? I need new gaskets myself.
These need to be 184-H184-H beacons. I'll keep my eyes out, but they're not easy to find.
