SG Lou's LP Build has be SCRAPPED !

[dazzypig]

Don't throw it away, finish it! Pine does some great stuff downsize, and it'd still be easily playable in that scale. You never know, you may have come across something interesting scale wise, it may play like a dream? Give it a try anyway, seems a shame to have come this far and then have to scrap it!

Lou.... if ya don't wanna finish it, i'll buy the hulk off ya and make a neck-thru out if it!!! Lemme know!!!

Anyone can copy, REAL MEN improvise.

I seriously doubt that the ANYONE will look at it and say "It's almost a millimeter off!"

Finish it and be proud of how you overcame a teensy bit of adversity.

 

[landsharkey]

Instead of trying to measure the 20mm reference on the drawing wouldn't it be easier to measure the length of the body along the centerline? I came up with 17.240" (or 438 mm).

Damn sorry to here that. I would still finish it no doubt. Either now, or put it away for a later date till the pain goes away.

Damn Greg, That made me feel a whole lot better about my builds. Seems thats all I do is come up with "adversity"

 

[ExNihilo]

Personally, I would lay this one aside for now and start over. Once you have completed the replica LP you really want, then go back and use this one to make something unique. That way, you will feel happy about everything.

And what is the lower bout width then? I bet it's not 13".

I scaled the PDF using a CAD program to get the 20mm reference right. The body is then 13.063 (or ~332mm). This is not easy to measure though.

 

[George "M"]

So, it's bigger than 13". Not much, but after lacquering it will be 334mm.

That sucks, get a new top and back but finish this one 2.

As cabinetmaker in the 80's we learned that working off blueprints for a 1:1 is not as good of a idea as you think, Even if you scale is correct, the printer will stretch the ink as will the paper as it moves in the printer/plotter.

Also to be exact, add some extra size for the sanding process if you can.

What to do? make one print 13.185 at the bout for the body, and one print 1:1 for neck angles and the like, use the tape measure to firm up the measurements and a LP guitar at hand for quick references.

last time i checked all lp bodies fluctuated in size a little bit. a .75 mm (1.5mm total if you add up the two sides) isnt going to break things. make it into a slightly smaller and thinner LP.

It's not that that is was just off 0.75mm - the whole scale was off by this much. So the whole body would be about 4% smaller and the 438 mm length would have been 420mm (or about 3/4") too short. And the body would have been 1/4" smaller on each side at the 13" point. It would be much easier to have the 438 mm (if that's correct) referenced on the drawing instead of the 20mm box.

That's exactly whats happening sharkey.the whole damn thing is off all the way around.

Well after reading all of the response to this I decided to continue with it.
I look at this way.......this will be the test bed for all of the procedures and if I goof up I know what NOT to do for the next build.
Thanks for all of the encourgement guys. !

Right on! Think of it as being externally weight relieved

You have to be careful with some rulers.. I have seen some small of the small metal ones (6" pocket ones) where the 1st mm is larger. I find it best to measure inside the ruler (from 1cm to 3cm) but you MUST remind yourself to add a cm to account for skipping the 1st. I usually do this with tape measures as you never know how accurate the end is (that slidding end for accounting for the inside or outside measurement) but when you forget to account for that skipped inch.. you will know it.

I just printed out the scale section on my printer.. 102% seems to be right on to the outside of the rectangle. Are measurements to the outside or inside of the rectangle?.. or inbetween

Atta boy, Lou!

I'd suggest ignoring the rectangle and measuring the body length along the centerline instead to minimize the measurement error.

Well i think i may have blundered on this even more.

Last night here at work I decided to use the Bridgeport milling machine and do the neck angle and pickup plane not thinking that i'm gonna need a flat area for the contour templates to sit on
I think i can work around that though. What dose concern me after reading
this thread http://www.mylespaul.com/forums/luthiers-corner/9035-les-paul-measurements.html is i know i went too far back with the pickup plane.

I'll post the pics later after I get up so you guys can see what i did and if it's ok or not.

 

[SG Lou]

BUMP............Anyone ?

 

[pinefd]

I was originally thinking that it should not be a big deal, and that you could just adjust the rest of the carve accordingly, but was waiting to see the pics that you mentioned in post #37.

SG Lou...you seem to be such an expert at the SG's....maybe the Les Pauls arent for you my friend....I think its a sign
