I'm building a guitar using one of Martin's A-frame neck blocks. I'm just wondering, do the braces that slide into the a-frame slots of the neck block need to be glued to the neck block when the top is attached or do they just slide in?

just slide in

Thanks.

Did you get A-frame bracing from Martin?

When I bought my kit, they sent an A-frame (mortise & tenon) block but regular x-bracing. I had to cut off part of the block where the A-frame passes through to make it work.

Also check the height of the top of the neck in relation to the top of the block & the body top to make sure it will work. In my case, I had to increase the length of the slot for the bolt along with enlarging the countersink. Here's a link:

did you get that kit from GMC at Martin Kevin ?

John,

I bought my kit from Guitar Maker's Connection (GMC) at Martin.

At the time, they told me that they could supply a mortise & tenon neck with accompanying block but they couldn't supply the A-frame bracing - only the original X-bracing.

...unless I misunderstood them.
