How about we leave at noon?

Try Ebay, Vic.  I bought a pretty good sized tube for only a few bucks.  I 

use it in plumbing quite often for things like attaching thermo discs to 

metal objects like water heaters etc.

Noon is fine with me...

It's after noon, so you guys probably left without me, as I was at  

Radio Shack buying some silicone heat sink compound for a few  

dollars...NOT $158. Those Rotax people gotta be out of their minds!

Oops, that "noon" message went to the wrong place .....   coming up on 100 

hours now, going to need plugs and that "silicon heat conductivity paste". 

Radio Shack eh?

Reading off the tube: "Silicone-Base Heat Sink Compound  0.23 Oz,   

Heat conductive-helps transfer heat from component to heat sink or  

chassis."  part #276-1372A



This is the stuff that Polyfiber calls for (or similar) to calibrate  

your iron before using it to shrink the fabric. It just conducts  

heat, plain and simple. Of course, if Rotax finds out you used the  

wrong stuff, phone calls to lawyers will follow. : )

Hey Lynn,



I don't think I would use a silicone based anything on an instrument that 

would be used on a surface soon to receive a coat of paint.  Are you  sure?

For calibrating the iron used in covering a plane with Polyfiber,  

they have you squirt a blob of silicone-based heat sink compound on  

the bottom of your iron, then lay their thermometer into the compound  

and cover with a 1/2" thick stack of paper towels. Then turn the iron  

on and calibrate/ record what the thermometer says for various  

locations of the irons' dial.

They also point out to be SURE to get all the silicone off the iron  

before using it to shrink the fabric. It's all there in the  

instruction book....yeah, I'm sure. : )

Lynn,



You are spot on.  I just checked my manual.  That said, I still think I 

would avoid any possibity of silicone contaminant on a paintable surface.



The electronics tech guy at Kitplanes suggested a possible replacement for 

the silicone stuff - the white goo painted on sunburn sensitive noses.  The 

Zinc Oxide is the heat transfer agent in both.  What I did is drill a hole 

in a piece of  aluminum and glued the thermometer bulb in it with some epoxy 

moxed with some aluminum grindings in it.  Put this on a towel face up and 

rest the iron on that and the broad contact between aluminum pad and iron 

bottom gives very good heat transfer.

Years ago when I ran a production photo lab we used heat transfer data

printing on the back of our prints and the temperature of the print head had

to be exact.  Too hot and the coating on the paper would blister or burn,

too cool and the print medium wouldn't transfer to the paper.  The system I

used was a series of wax pencils that would melt at specific temperatures.

Simply mark the iron with say the 285F pencil the 300F pencil and the 315F

pencil and when the first two marks melted and the third one didn't you were

right at 300F..  Using that technique you can quickly locate any hot spots

on your iron as well as quickly calibrate the iron.  The two advantages are

you can quickly test the iron and clean up is just a wipe with a paper

towel.



If you want I'll dig out the pencils and get a brand name for you.

Good idea Lowell. I don't know why Polyfiber does it their way, but I  

didn't find the silicone very hard to remove on either iron....yup, I  

dropped one. : )



I just came home from a lake landing across the road....put a couple  

of logs on the fire, and I'm off again....ya can't beat wheel-skis  

for havin' fun!

Was it Temp-a-cil? or something like that, Noel? I saw them at the  

welding store.

I'll check for you the next time I'm in the garage...  They're in my tool

chest.



They are deadly accurate and come in several temperature indicators.

The good folks at an aviation engine repair near here use them to  

determine when the cylinder heads are at the correct temp for  

installing valve guides, seats, etc.
