A Checkered Butt Extension for a Guerini

 A checkered but for a gun with a drawbolt-retained buttstock presents a bit of a challenge because of the need to access to that very bolt.  

The way the big manufacturers do it is, typically, to simply use a buttplate of conventional design but made of the same type of wood as the stock.  They are however, never made from the same piece, nor is the grain orientation in the same direction, which would compromise the strength of the buttplate.  Needless to say, this, combined with the presence of the buttplate screws doesn't make for a very convincing representation of a checkered butt.  It just looks like a wooden buttplate.

The other common method is to use an oval (usually more of a rectangle with rounded corners) plug of wood, also retained by two screws, inlet into the sole of the butt.  In some instances, this doesn't look too bad but the screws still spoil the look.

The drawbolt in a Guerini over/under is of the Allen (or socket) head type and is held captive by an aluminum plug pressed into the bolt bore, which not only prevents the bolt from being lost, it also acts as a guide for the Allen key, thanks to the "funnel" machined into the rear end.  The captive bolt means that the only access necessary is a 6mm hole (to comfortably accept the 5mm key).  Figuring that a single, small hole in the butt would probably look a whole lot better than two screw heads and an obvious seam, that is the direction that I took.

Since this was to be a considerable extension, the weight of the added piece had to be considered.  The gun's balance was preserved by boring multiple holes completely through the extension, which were then plugged with shallow plugs.  The plugs were turned from the same piece of walnut with the same grain orientation as the extension.

The plugs are epoxied in place, making sure that the grain followed that of the surrounding wood.  The access hole also got an aluminum "bezel" to prevent the checkering from getting beat up around the hole during future maintenance.

After the epoxy cured, the but was shaped in preparation for finishing and checkering. 

All finished.  The plugs are all but invisible.

Another Bad Idea That Refuses to Die

The following are my thoughts regarding stock bending and why I'll have nothing to do with it:

Any gun of quality manufacture has its cast (be it on, off, or neutral) "built in".  Meaning, the cast starts at the point where the frame meets the wood.  In many instances, the frame straps are actually displaced in the direction appropriate for the stock's intended cast.  In other instances, the frame straps are straight but the cast still originates at the frame/stock juncture because the inletting will be offset.  It also follows that the triggerguard strap will follow in the direction of the stock's cast.

Now imagine if you will, bending a cast-off stock into a cast-on (or even neutral) configuration.  With the frame strap/inletting situation being fixed, the only option is to bend the wrist (hand) portion of the stock.  This means also bending the triggerguard tang to match.  For this thought experiment, we will disregard the difficulty in actually bending the wood and the vanishingly slim probability that it will stay in its new configuration.

Think about what we end up with in the above scenario: a visibly "S" shaped gun with the head of the stock heading off to the right, bending through the wrist and the balance of the stock veering off to the left.  Things look even worse from the underside of the gun, where the triggerguard's bow and its tang are no longer in line.

The drop situation is no better as this is another dimension that is "built in" and the same limitations apply.  The bend would necessarily need to be applied through the wrist and, if the bend is of sufficient magnitude, it will affect the aesthetics of the toe-line of the stock, the pitch of the butt and the fit of the triggerguard and frame tangs.

Stock bending is one of those things that is long accepted but that doesn't mean that it is, or ever was, a good idea.  The wood is, by necessity, being bent through the area of least cross-section and bending entails setting up enormous internal stress in the fiber cells of the wood, both tensile and compressive (tensile on the outside of the bend and compressive on the inside of the bend).  It is these stresses that will, eventually, cause the wood to return to its original state (or close to it).  If the wood is bent far enough that the fiber cells break, the wood will stay in its new configuration but its strength will be greatly diminished.

Bending, or more accurately, attempting to bend a stock that far is a bit like bending your car's body to make it go where it should, rather than altering its wheel alignment.  Bending a stock is a "low cost" expedient with a low probability of long-term success that also entails significant aesthetic compromises.

A Neglected Prussian Daly

 This Daly had clearly sat unused, and apparently uncared for, for quite some time.  The forend tip and grip cap were missing, it was coated in rust and caked-on dirt and it didn't "present well".  The client was willing to bet that this gun was a diamond in the rough so he sent it here to be properly cleaned and have it gone over and through.

The before and after condition is fairly startling, and highlights the importance of employing proper methods of cleaning, in order to preserve any original finish that may remain, as well as any patina that the gun has acquired over the decades.

I know, everybody thinks that cleaning a gun is a "piece of cake", "it's easy", "we'll shine that right up".   Well, I've too often seen the results of well-meaning but ill-informed attempts at cleaning vintage guns and it's often not very pretty.  Here's a hint, wire wheels and wire brushes are never the answer.  Neither is any sort of abrasive compound like Flitz or Simichrome.  That kind of treatment may well get the gun "clean" but its value (and looks) will surely suffer for it.

Before:

After consulting with the client, it was decided that the missing forend and grip cap would be made in ebony.

After:

A 20 Gauge Daly BLE

 Here is a Charles Daly (Prussian of course, I don't work on the "other" kinds) BLE in 20 gauge that is also a two-barrel set.  It needed the rim recesses cut because the original rim cuts were of too small a diameter to chamber any current shotshell.  It also had a few other minor issues.  The trigger plate screw had apparently suffered some damage, so an enterprising "gunsmith" widened the slot (a lot) in order to clean it up.  The solution is, as usual, a new screw.  

The threads on the triggerplate screw are proprietary, so after juggling change gears in the lathe, they were single-pointed.

Then, work proceeded in the usual manner.

After I engraved, case-hardened and "aged" the screw, that part of the job is finished.

The extractor retainer screw in one of the barrel sets was also damaged.  The same procedure was followed to correct it.

The forend wood also need some attention due to substandard repairs, including the addition of a non-original screw to retain the forend tip.

After dissolving all of the epoxy, this is what was left.

The damaged areas were prepped to receive the new filler pieces.

The filler pieces epoxied in place.

The finished repairs.
