Larger format drawbot

I’m getting geared up for some larger drawings.

I didn’t have a wall to mount the spools so I made them able to mount on a door frame or any board.

The new clamp gondola works nicely but I forgot to pick up some washers for ballast today. Perhaps I should use stones for ballast. Either way, I need a way of attaching. As you can see I’m using a couple wrenches.

I have the board mounted vertically and I suspect it will change the dynamic a bit as compared to the Baby Drawbot which had a steep angle.
