Hi Roger,

Yep, I used flux. It's there in sentence #8.

>>Hi Everybody,

>>Well, I tried my hand at silver soldering Saturday and didn't have any 
>>success. I tried for about 4 hours and just couldn't get it.  I practiced 
>>on a piece of steel. Got it red hot and touched the silver solder to it. 
>>It melted and made a nice little blob. After it cooled I smacked and 
>>whacked on it and it wouldn't bust loose. I thought hey that's pretty easy 
>>so I tried it on my crankshaft.  Put my flux on and heated it with my 
>>oxy/acetylene torch with a brazing tip in it.  Got it red hot and touched 
>>the silver solder to it. It melted for about 3/16 of an inch and quit 
>>melting. I heated it up again and as it got red hot, it started to blow 
>>out my other solder. It would just not stay hot to apply my solder long 
>>enough. As soon as I got it red hot and started to apply the solder it 
>>would cool off and not melt the solder. I tried the cutting tip to get it 
>>hotter and that didn't work either. Actually started to melt the steel in 
>>a couple spots, then quick started to apply the solder and same thing, 
>>just 1/8 to 3/16 and it would cool off and not work. Then reheat and it 
>>would melt the other solder out of the way and have to do it over again. I 
>>messed around for about 4 hours and didn't get anywhere. I was not a happy 
>>guy! After almost throwing the whole damn model in the scrap bin from 
>>being so frustrated, I figured I'm not cut out for model making. After 
>>sleeping on it for a day I took the welder and welded the crankshaft. I 
>>did a little at a time so it didn't get too hot. Not sure if it will be 
>>distorted or not, I didn't really care at that point. I did put it in the 
>>main bearings after welding and it still turned over and didn't bind. So 
>>that's my silver soldering failure story.
