Ivison Guitars '59 DC Model - Build Thread

What's Hot

I thought i'd share, for anyone that might be interested, how I build my DC Model. They are based on an original 1959 Gibson Les Paul Junior that I owned (twice!). It was such a great sounding and playing guitar, I decided it would be a perfect blueprint so I set about measuring every last detail. If this gets a bit 'cork sniffy' I apologise.

I did set out to build an exact replica but over time and after studying 5 different Juniors and a Special the one thing that become consistent, was that none of them were consistent, they were all slightly different! Now, it's worth mentioning here that a lesson I soon learnt and one to bare in mind was that, even though we now covet these Golden Era instruments, while they are fantastic and one of the best guitars Gibson ever made IMO, they were in fact literally thrown together student models, being knocked out for $150 bucks.

So I decided, while I would stay as close to vintage as possible with modern materials, I would need to take averages where necessary and just try and make the best guitars I can so there are a few subtle changes, nothing major (in fact you'd probably never notice if I didn't tell you!) , just little things which I feel make for a better guitar.

Much of this will be done in real time, I already have the bodies cut, thicknessed, routed and sanded so i'll document that first.

So it all starts here:



Enough African Mahogany for 10+ bodies so I need to manhandle that home and cut it into manageable sizes...



Once I no longer need a block and tackle to moving the lumber around(!), I start by rough cutting the DC body shape out of the 1 piece blanks:



And then over to my thickening jig to bring it down to 45mm. The originals were mainly 1 3/4" so this will give me a little extra for final sanding:



Then tidied up on the router table. I've also routed the first route of the P90 cavity. This route is 15mm deep as per vintage:



At this point I have selected which bodies have the best grain for TV Yellow and which will look nice in Cherry Red. Next I start to hog out the neck mortice with a forstner bit and we get, what I like to call, the frightened rabbit....



Then I clean up the neck mortice and route to 35mm:





I also route the P90 'shelf' (where the baseplate of the pickup sits) at 7mm.

Next I drill the pot holes from the front about 30mm into the body (once the cavity is routed this gives me a nice, clean hole edge), flip it over and hog out the control cavity then route this to a depth of 40mm which is very slightly deeper than vintage to allow for the CTS TVT pots I use.



The jack hole is also drilled out with a 25mm forstner bit at this point. 



Next up is the body round over. There are a few options here. A '58 single cut, has a much tighter roundover than a '59, almost like a 50's Tele. The '59 had a much smoother body edge so I set my roundover bit to cut slightly lower than normal and then feather out the edges by hand to meet it, like this:





This leaves us with a '59 DC Body:





More in a few days!

    Ha! These are far from thrown together, I have 'refined the process' into a borderline OCD, Vintage Nerd approach.... ;) Drop me a PM with what you're after, i'm not sure Making and Modding is the place for sales, mods?

  • Fantastic as always Neil, I think I maybe asking for a double cut in cherry at some point in the not so distant future.

    Loving it so far, and this thread is going to be epic by the end.
    Is the neck pocket route flat (at the 35mm depth you said) or is it angled to get the right neck angle?
    Always be yourself! Unless you can be Batman, in which case always be Batman.
    My boss told me "dress for the job you want, not the job you have"... now I'm sat in a disciplinary meeting dressed as Batman.

    Thanks @BigMonka ;

    The pocket is flat and then the heel of the neck is cut at 2 degrees (vintage spec although it all depends on the bridge/P90 used, mine are cut at 3 degrees.) to get the angle :)

    thanks for the brilliant thread. another inspiring one that makes me think 'well that looks possible...' & i have to fight the urge because i secretly suspect i would get into a terrible mess trying.
    the step by step photos (with tool types & dimensions listed) hit all the important stages in crystal clear detail. much appreciated.

    i did wonder about a couple of things.

    the wood seems very light at the start of the shoot and redder at the end. does the wood surface oxidise to a redder hue once it has been cut for a while, or is it just a lighting thing? or is it just the species (some are brown, some are red, some are golden)?

    also the neck pocket bottom seems incerdibly thin. i guess that's because these are set necks so the glue will achor to all sides of the pocket, whereas a bolt-on only attaches to the bottom.
    would a bolt on version need to be double that neck pocket bottom thicknesss or even more?

    Thanks for all the nice comments so far folks, it’s much appreciated!

    @vale The wood does oxidise slightly after working but it’s also a combination of lighting too. Once sanded it returns to the lighter colour.

    The neck pocket has 10mm left at the bottom as per the originals. It’s glued on all sides of the tenon so it’s perfectly stable and there’s no fear of it coming out. I’ve not looked into bolt on Junior style necks (heaven forfend!! ;) ) but the depth of the pocket should certainly need to increased by a considerable margin IMO.

    I agree Neil, don't ever bolt one of these necks in, that should be a punishable offence

    A strat and tele neck pocket isn't as deep though and they work

    If its a bolt on,its not a Junior. Always fancied building one of these from scratch but the fret work scares me. These sort of threads are always fascinating.I've built up one of GSPBASSES double cuts which is now a firm favorite and just as good as my Gibson SC Junior. They truly are fantastic guitars. Everyone should have a Junior.
