Trammel Attatchments

grabcad

this is a few simple parts that can be used in combination with a 10mm square bar to create a trammel. The scribe inserts are small needles but the model can be edited to suit what material you have. The trammel is used for marking large radius's and with the straight edge attachment it can be used to mark and correctly spaced line from an edge. The attachments are held to the bar with set screws to allow easy adjustment.
