@HereIsJT and Simon
We live and learn. Well the smart ones do, while on the other hand I have launched straight back into doing the same thing again. LOL.

Silly question.
Couldnt you just empty a tube of CA glue down the crack?

That would be my silly question also...it's just a crack.

cheers, Mark.

You could, but the force that causes the crack is still there, so the most likely scenario is it would just crack again down the next ply

@Sam and Mark,
Those photos were showing just part of the split. It went a bit further than that.

And it tended to get considerably worse when I stuck a chisel in there and bashed it with a hammer and then threw off the back landing. LOL

Needless to say I doubt that it can be restored now.

cheers guys

Ah we have the luthier's Nick Kyrgios in our midst...hammer abuse hehe.

cheers, Mark.

The pattern of the end grain should indicate how likely the wood is to warp and the direction it will curve. If it’s almost straight, then you should get minimal warpage as it dries/seasons further. If it’s a deep C-shape pattern, then differential shrinkage between the growth rings will pull it further into that C-shape IIRC. Just coming back to me from something I saw or read a few years ago. Some if your pine looks pretty flat grained and some looks pretty curved. A more careful or fortuitous selection of the planks used and you would probably have been OK. Something to consider for the future.

@Mark
In my defense I actually used my home made wooden mallet, so not actually "hammer abuse". LOL

@Jim
That was my thinking also

@Simon
I have had a good run with these laminate bodies to date and I think I had grown a bit complacent with my pine selection. I think this body was a timely reminder to pick up my game. I bought some more pine and ply and went through quite a few sheets looking for the best pieces.

I have already cut out and glued a replacement body but this time took more care in orientating the pine to hopefully reduce the odds of this happening again. Time will tell.

Thanks guys

OK, I've started shaping the new body while it is still in one piece. Although I am aiming for a very traditional LP Jnr front the back will be shaped a bit for comfort. All my practice is done sitting down so theses mods are primarily to make it more comfortable when seated.

I intend to stain the guitar with a very traditional Jnr type burst so I am hoping that all of the cuts in the back will be camouflaged by the darker outer stain.



I'm trying to avoid the traditional Fender style belly cut.


Not a very good shot but here you can just make out what I call a "Lap" cut in front of the control cavity.


I have also included a cutaway for better access to the "dusty" end of the fretboard.


The Lap cut and cutaway and the bits I used to drill the neck ferrule holes.


The Neck ferrule holes in a bit more detail. They are still a bit rough due to crappy bits but they should clean up to a respectable standard.

Tomorrow I hope to drill the bridge posts and then start staining.

And more problems....

I had painters tape on the body so that I could mark exactly where the bridge post holes would go. I used a punch to mark the position and proceeded to drill the 12mm holes with my brace and bit and I didn't realise that the bit had wandered on the tape and I drilled 2 perfect holes IN THE WRONG PLACE!! That's a lesson I will remember for the future.

Not deterred I got out my plug maker bit but it is of such poor quality that I was not able to drill a plug with my hand tools and finally I had to surrender my ethos of hand tools only and get out my electric drill.


Did I mention that the plug bit was poor quality? It is so bad that it burnt the plugs and discoloured them so that, even though I lined up the grain pretty well, the plugs now stick out like the proverbials.

I am not overly concerned as I am pretty sure that the post holes in the soft pine are going to deform with the string tension and I will have to look into reinforcing them in the future.

Last job for the body is drilling the hole for the jack plug.


At least I got something right with this build. LOL

Cheers guys
