FYI: ?Newcomers may not be aware of all the useful bits of information on the Unimat IO site. In particular, in the "files section¡± check under "new files" and look down the resulting list to find "PDF Drawings¡±. ¡°Unimat_012.pdf" is a dimensioned drawing of the standard circular saw arbor. Athe top of the plans list is also one for the stock ¡°tool block¡±.
Cheers, Bill
