Task today was to put all these parts..

back together. Some needed a coat of fresh grease. There is an axle...that had a bad habit of either sliding back out, or, turning around the wrong way...
Each part had to go in just so....and in a certain order...small slotted bolts to adjust that brass barrel...plunger and a spring needed to go in, be held in place, while the next part was slid in...so when the lever is moved part "A" connects to the plunger, moves it to unlock the swing arm....a lot of fussing going on..

Top view. Larger end of the plunger is the locking pin...the shaft with a spring..

Other end. Slotted plug adjust a slotted barrel, slot fits in a groove in the frame's quadrant. Slotted plug adjust how tight or loose the fit is. There is also a "keeper" ( looks like a lateral lever) that holds the lever in the in-locked setting. So you can slide the arm to the next spot, without fussing with the locking pin.
was able to adjust things enough, that the arm slid into place, so I could install the King bolt and it's collar..

Collar is a very tight. slip-fit...not supposed to move. King bolt has enough room so the swing arm can rotate. Pnce the swing arm is all adjusted and ready to go, THEN I can add the pointer..

Because those 2 bolts will not allow the arm to slide into place...BTW: those are not degree settings on the scale....those tell you how many cuts that setting needs to do, to make a certain angled box,,,,"4" being a 45 degree cut, to make 4 sides of a box.

There IS a zero ( 90 degrees) then it goes to 24....then on down to "4".
This part is now assembled...stay tuned, was a busy day..
