Interview w Len re: Restoring old Nationals
June 20th, 2008Hello my friends,
first off, let me say I’m sorry for the delay since the last entry. I’ve had a slew of spam attempts in the last couple weeks that I’ve been deleting before they can come on.
Today I’d like to answer some common questions and give my view on working on old Nats.
First off, let me say I’ve now gone thru around 300 vintage nats over the years. Most need the same typical work on them to get them playing to their potential again. The standard problems I see are…
-warped necks
-cracked or crushed cones
-dried out fingerboards
-dents, bumps and bruises
-Bad neck angles
-Replaced tuners
Regarding the necks, that along w poor neck angles and cones are the worst offenders. Many old Nat’s that were left in barns or attics were still strung and tuned close to pitch. 30 plus years of that in brutal heat and cold will warp the staunchest neck. Now, keep in mind, most all of these old necks DID have truss rods in them. Problem is, they often are not doing anything to keep the neck straight. The method they used was just routing a deep route into the neck under the fingerboard and pushing in a metal pipe and securing it w hide glue. That glue often shrank, and the pipe often has moved inside and doing nothing to help. IT can be reinstalled using modern epoxy, but often the neck itself will need to be either heat pressed straight or the bow sanded out of it on a flat surface. The fingerboard can then be re installed and the neck straight.
As for cones, they can often be massaged back into shape and be ready for several more years of service. The problem comes up often where they are actually cracked, especially on the ones that had the short added impressions around the outer edge. (pics to follow) Although the idea was good, add stiffness, the stiffening impression actually became a weak spot that often cracked there. You can tell by holding the cone up to a light and look from underneath. There often you can see light coming in from various cracks you may not have noticed. Another problem that is common is that the cone is just fatigued. It can be compressed downward from many years. I can reshape it to it’s original shape and size, and after stringing it up and waiting overnight, you’ll see the next day it begins to collapse again. It just doesn’t have the structural integrity anymore to keep it’s stiffness under the string pressure up above. At Vintage Nationals we try our best to save every old cone. We replace them ONLY as a last resort, not just because we like new cones. (I do love Nationals Hot Rod cone, and it’s the only replacement we use).
As for fingerboards, this is also an area of concern. While again, we try and save most fingerboards, there comes a point of diminishing return. Yes, you can use epoxies, superglues w wood dust, etc. and fix most cracks that are common. To what point though? Many of these old fingerboards are SO cracked and DRY, it’s not worth it. Again, we rarely need to replace a board, but it is a common problem. When you reset a neck, you are moving the headstock back towards the back of the guitar. This causes the fingerboard flap to rise upward vs. the body by a small amount. With a healthy fingerboard, this little but of downward pressure when you secure the flap to the body is no problem. With a super dry board, the flap will often just snap off right at the 12 or 14th fret. The ebony seems to hold up better than the died maple boards, but each can have this problem. (pics of ancient boards to follow). I must say, if you have to do this procedure and use a new duplicate board, the playability w a modern radius and new frets are fanatastic. Again, we ONLY do this if absolutely necessary, but if a fingerboard is shot, it’s shot and needs to be dealt with. All or duplicate boards are made to fit from the National factory and are exact replicas of whatever came off the guitar.
Dents and bruises are a challenge in themselves. I use an assortment of autobody tools along w some I made myself to get out most tyical bumps and bruises. One thing you see a lot of nowadays is 14 fret Style O’s getting cracks on the side bouts. You don’t see it on steel body 14 fretters because unlike brass, steel has no memory. Bend it, it stays. Brass does have a memory and when you make the exteme bends used on a two piece 14 fret body, the bend wants to go back some, creating tension in the body that is nowadays manifesting itself in tons of side cracks. Many dings we just leave alone and call it normal wear.
BAD Neck Angles are the most common malady. You have a neck that’s been under tension for 70 odd years. You often have heavy gauge strings on top of it all, and if the guitar sat for years under tension, something has to give! What good is an all original untouched Nat if the neck angle is way off? If the action is 1/4 inch at the twelfth fret, and the saddle has already been sanded down to the nub? If there is essentially no downward string pressure on the cone, killing the volume and creating a ton of rattles? Oh, its all original, but more likely is barely playable, unless all you play is slide, and it won’t sound near it’s potential. Resetting the neck is something that is jsut part of normal maintenance. In the process, the headstock moves back slightly to it’s original position, the action comes down towards the fingerboard, and you now have the correct downward pressure from the strings onto the saddle/cone. Rattles are gone, volume improves, and you can actually make chords all over the neck! If it needs it, it needs it! I do cartwheels when a Nat I buy does not need a reset. Problem is, that is a very small percent that don’t or that have had one done correctly along the way. I’d rather never have to do one, but c’mon, 70 years of tension, a minor adjustment after that long does not seem unreasonable, does it? If you think it is, come on by sometime and show me how you go about playing some of the old stored away Nat’s I get in. Then give me your opinion!
Replaced tuners are usually not an issue on old Nats. Although many come in w replaced and incorrect tuners, almost never was there any routing or headstock alterations. Usually it’s just another strip type tuner that fits the same way as the original, which probably lost a button or two along the way. Thank God theres no Grovering and routing as has been done on so many electrics over the years.
RENECKING…. Well, here’s another area of conflict. Although I have renecked many old Nat’s along the way, i’ts always for a good reason. If I reneck a single cone sq neck, I keep the neck w the guitar. IF, as I just did recently, someone has butchered an old sq neck by rounding it off by hand w a file, I’ll replace that. (see the 14 fret O just listed). The Bakelite necks are essentially useless. I often will replace these with a duplicate neck. (see the triolian w Palms currently on the site). The old neck goes with it, but a warped bakelite neck is no fun to try and play or work on in any manner. I never reneck a roundneck unless the current neck has issues that are not repairable. National made 10’s of thousands of guitars. The 10-15 total I’ve renecked over the years is not going to put a dent in the supply of original models. I do it when it’s needing to be done, not just to do it. We use exact replicas w attention to detail when it’s decided it’s needed and they end up playing like a new National w the body and cone of the original, a great playing guitar it is.
Well friends, there you have it. I’ve taken some flak along the way about working on some of my Nats. I can say as I mention above, ONLY when it’s needed to I make these changes. Don Young of National once said to me, “I get a kick out of it when guy comes in w his old Duolian w a crushed cone and bad neck angle, and starts telling me all about his vintage tone I can’t produce. What a crock!” That’s pretty funny. I’d say this, if someone comes across an old Bugatti from the 20’s they want to restore, are they going to use the old tires or use new ones? Do they keep the old leather interior of have it remade? When rebuilding the engine, do they only use old parts or make use of current technology? Some old Nationals need work, period! I do whatever the minimum is needed, never add to any finishes or take away from them, and end up with a guitar that sounds and plays fantastic. One that can be played all over the neck. One that has it’s full volume when played. One without rattles and buzzes from poor neck angles and faulty cones. Isn’t that how you want your Vintage National to play? I know I do! Thanks for reading, I will flesh out this arcticle w a series of pictures illustrating my points. Best, Len
