Need to hang two homemade closet doors at my daughter's place. We are stuck with hinges that have radius-ed corners. Don't want make a template for the router. Want to chisel the relief the old fashioned way. Any tricks you guys can suggest when it comes to the rounded corners.
All I can think of is to scribe the radius with a box cutter blade and then possibly nibble away at the corner with one of the rounded lathe (wood turning) tools.
Also: The jambs are mdf. Any special advise on chiseling mdf???

All advise appreciated. (note: that's a total of sixteen corners)
Thanks
