Here was an interesting project from yesterday evening. Had to bore these 3 holes out of position. Ended up running a 14in piece of hydraulic hose as our universal joint. And worst of all I finally had to sacrifice my long boring bar to be able to fit in the given area.

Here's today's project. Line bored the bucket pin on the dipper stick.

Here we have a cat 336 quick coupler. This unit is getting a complete rebuild all welds are bing repaired and it is being linebored. We will be selling this part so if you need a remaned quick coupler, this unit will be ready in about a week.

Here was a project we did that turned out to be a bust. This is a final drive housing on a D6R dozer. The bolts came loose allowing the sprocket to swing down and and sheer off the fl**ge. We machined the remainder of the old fl**ge off and cut a new fl**ge and machined it to a press fit. However for some reason no matter what we did the welds continued to Crack out even with high nickle filler. In the long run we ended up having to call it a loss and buy new.
