Bad news, although the 1E has the height for bowl and tray templates the diameter is too large. At this time the largest diameter bowl and tray bit offered is 1-1/4". These bits have a 1/4" radius. Infinity Tool offers an extension with an OD of .118" that is designed to work with these bits. The Xtreme Xtension measures .135" and to clear the screw the Musclechuck would require a bit with a 1-1/2" diameter.
I am going to get on the phone and see about getting a bit manufactured with this diameter.
