Thinning the neck on a The Loar LM-600
Someone has asked me to thin the neck on a The Loar LM-600.
I've not see the mandolin yet, but Gary tells me it's a very thick, deep, rounded neck. He wants a little bit more of a gentle V profile (not as much V as an Eastman or Kentucky) and would also like a little less depth front to back.
The V I'm totally happy to do, but not knowing how deep the truss rod is set in the neck I have no idea how much can safely be shaved off the back of the neck.
I think I've seen dealers say that they have reworked necks on The Loar mandolins, but I can't find the threads now I go to look.
Does anyone have any information on thinning the neck on a The Loar LM-600. How much margin do I have?
