I have the Whelen strobe power supply to run 3 strobes ( HDACF).  It's 

got a mounting plate that is about 6" square. It weighs 2 Lbs.  I want 

to mount it just behind the baggage bulkhead some where.  First idea, to 

simply mount it to the belly skin was rejected.  The skin's not braced 

enough.



Putting a shelf of some sort  from the central rib to the side skin 

seems like too large a run and gets in the way of accessing the elevator 

bell crank unless youplace it rather far aft.  I'd like to keep it as 

far forward as possible.



I could make a mounting "shelf" attached vertically to the aft side of 

the skin that screws to the baggage bulkhead, down low the lower 

corner.  Problem there is you'd have to remove or diconnect the thing 

everytime you removed the skin.  It's an easy installation, though, 

since you can work on the bench instead of int he plane.



Another  idea is to mount it oriented vertically on the side of the 

fuse,  up high.  One bracket attached to the bulkhead itself, the other 

to the skin.  The skin's flat there.  A piece of 1/16 angle 7" long 

rivetted vertically between the 2 J strips would be plenty solid and I 

think the skin is strong enough there.



The baggage floor is rivetted down so that closes off some possibilities. 



If any one has some ideas or photos on a web site, I would be very 

appreciative.

Obviously not a direct answer to your question, but why not mount it between 

the battery box and the fuel selector?  Make a little shelf between two of 

the floor stringers and put it on the shelf. This is also a good location 

for your ELT, oxygen bottle, or fire extinguisher.

Here's what I did, I had it on my web site at one time but have since removed some of the older stuff:

 I ran conduits under my baggage floors to run wires.

Tom,



    I used screws instead of rivets to fasten down my right side baggage 

floor. I added two stiffeners to the floor panel between the ribs and 

mounted the power supply upside below the baggage floor. Whelen said it can 

be mounted any direction and cooling was not a factor. Also, I have no 

strobe noise in the headsets, even with the comm antenna on the belly under 

the seats.

Kyle:

    Yes, that's a good location, functionally, but likely to get 

kicked.  I'd want to make some sort of cover for it (there's 5000v in 

one of those wires).  Besides, I plan on putting the fire extinguisher 

there.  Also, the wires from the strobe supply have to end up on the aft 

side of the wing spar, so it's convenient if they start out on the aft 

side of the wing spar to begin with.  That ay only the power & ground 

wires cross the spar.

I would caution you on putting your strobe power supply in a location near 

to anything that may leak fuel...  Strobe power supplies send very high 

voltage to the strobe heads and it would make for a very bad day if for some 

reason your fuel selector should happen to leak on the connections to the 

strobe heads...



Just an FYI...

Tom, 



My RV sports two Whelen power supplies, and I mounted a unit to each outboard wing rib.  In your case, perhaps it is advantageous  to mount your single unit to the right wing given that side is usually built a bit lighter than the left wing if your landing light and pitot installation is located on the left wing.  The photo illustrates my installation technique on the right wing.  As shown, the wing tip rests atop the wing showing the internally mounted VOR antenna bolted inside the tip.

Tom,

 

 I mounted mine to the bottom rear of the baggage bulkhead and it's never been a problem. Removing it is as simple as disconnecting a few plugs. It was the simplest and lightest way to mount it and I'd do it the same way again.

Mine went on the aft side of the baggage bulkhead, slightly left of  

center and just below the seam between the two halves of the  

bulkhead .  It has worked well.  Now that I have done many  

inspections, mods and maintenance I would recommend putting it on the  

top half bulkhead.  Reason being that I have not had the need to  

remove that one in the last several years.  There fore I would not  

have to unplug the power wires each time I take off the bulkhead for  

inspections etc.



I also like Bobby Hester picture, since that belly skin is an oil  

canner and those rails should stiffen them up a bit!

Hmmm, I don't think that will help with oil canning. It looks as if the rails are suspended on each end at the bulkheads and not in contact with the skin. I bought another rib from Van's - the one that the elevator bellcrank is mounted to (sorry I don't have the part # at my fingertips) and fit it parallel to the existing one and made a sort of avionics deck.  

   

[img]cid:image001.jpg(at)01C69E00.A054F9F0[/img]  

   

Things wound up crowded and I mounted on the side of it. That black thing at the aft end is a remote compass sensor which I’ll probably end up not using.

Ed, Just some information for you... I have the  AK-450 ELT as you do... The mount for the mounting strap broke (at  around 300 hours)... Not sure why, but might be from unhooking it and re  hooking at battery change times or from viberation... you might think of beefing  this up... for if it came loose back there... not good...!

Sheldon,  

   

Thanks for the heads up. This airplane isn’t flying yet, but I’ll make sure to put a line in my inspection checklist to give it special attention when it does.
