After this, I wanted to finish sanding/cleaning/prepping to paint inside the cowl before I welded the top cowl panel patch on. I grabbed my Dent Fix Eliminator, otherwise commonly known as a crud thug, attached the air hose, depressed the lever and......nothing. Just air coming out the exhaust. Thing worked just fine a month ago and now nothing. I couldn't turn the wire wheel by hand, so knew something was seized up....dang. Long story, short, it took 45 minutes just to get the danged spring pin out of the handle to take this apart. I REALLY need to get a better set of small punches and I'll leave that part of the story alone. Anyway, I had an exploded view page in the kit and used that to figure out how to take it apart. It must have had moisture in it from the last time I used it and the vanes on the rotor stuck to the cylinder. I was able to work it enough to free it up and get it working again. That whole process consumed the last 1.5 hours of my time for this project last evening. Today, I used it and got everything cleaned up, papered and sprayed with SPI epoxy primer/sealer. Tomorrow will get Limco single stage color and then the cowl top will get welded on. Are all y'all bored to tears yet...
