Put a turnbuckle in the rope on your drawboard and you can get extremely precise with cam synch. You can also clamp your drawboard to a workbench to draw in an upright postion and there are also plans on AT on how to build one right on your workbench upright. Lots of options.
If you want to go all in you could look into a Kwik Shooter and then have a draw board and shooting machine all in one.
