Bruning Drafting Arm Model 2699
(OP)
thread769-192272: related to the 60's, drafting tables
I have decided to setup my old drafting board and Bruning arm for my grand daughter. She is taking Architectural drafting in technical school. I feel that one thing that is not stressed very well in CAD is lineweights. Nothing in most cad drawings really stands out. But my major problem is the setup of the Bruning arm. It's been 30 years since setting one up. Can anyone help me?

Assuming the head is actually square that is it, however you can check it all works by tipping the head around at 45 and -45 degrees and drawing a line with the X and Y rule, they should be parallel, if not you have to get it as good as you can.

Then measure up at each end to see if the machine is set square on the board. Adjust the two clamp screws if it is not to parallel the line to the board. Then go on as described by ajack1.

P.S The drafting table I mentioned in the earlier thread I never did get rid of. It now sits on my back porch under a cover, and occasionally I will go out and use it to lay out something, then bring that back in and draw it up in CAD.
