In my first post here, I showed a picture of the Mounting Bolt and Spacer. The picture below includes a non-OEM Mounting Bolt I received with a Jig Saw. It is the one on the left. You can see the difference in the overall length of the bolt and the length of the threaded end. This bolt can be used but does require washers to use as spacers. Without spacers the bolt does come in contact with the Drive Sleeve Spacer inside the Headstock before the Jig Saw is tightly mounted. This non-OEM Bolt can easily be spotted, when seen on its own, by the difference in the bolt's smooth sided head.

So now that I have a bolt thanks to a kind soul, I have a new problem. One of the leveling set screws is seized completely.

The slotted head is chewed up a bit so I’m concerned about using too much force on it. I’ve treated it with penetrating oil several times and used a rubber mallet to try loosening it, all to no avail. I am extremely hesitant to try drilling it out because I’m certain to damage the threads at the very least.

Does anyone have a suggestion as to how to get this thing out?

Bill,

Can you post a picture of the Set Screw in the Main Frame? I may have suggestions based on what I see. In the meantime, continue with the penetrating oil.

Here are a couple of different angles of the top and one of the bottom.
