Combination Square Attachment (pin hole locator)
The tool is an attachment to a combination square for locating and marking the stock to underlug pin hole locations. This tool is a very accurate method for marking barrel underlug pin hole locations, for eventual drilling of the stock and the underlug. The attachment tool was designed for use primarily on octagon barrels but could be used on other barrels if done carefully. The square attachment alone does NOT come with a combination square. The tool's pin aligns with the square's head edge so positioning the pin where you want the underlug hole makes alignment simple. It will fit a square’s scale that is 3/32 of an inch thick or less. That includes every square I have tried. The Stanley (12-inch), Empire (6-inch) and Starrett's (12-inch, 6inch and 4 inch). The Starrett 12-inch had the thickest scale at 3/32 inch. The attachment is fully adjustable to fit all common 12 inch or smaller combination squares. A 4-inch or 6-inch square is really the handiest to use. A 6-inch combination square is the one I supply with the combination package. The attachment will be in place ready for use.
Tool use: The 1/16 inch on the attachment must be aligned with the edge of the square’s head, an important step. The following picture shows the alignment.

The square holding the attachment is then placed on the top of the barrel, stock removed, and the point is positioned to the location where the hole in the under lug is desired. You will need to slide the square’s scale up or down to align with desired hole location. Because the attachments pin is 1/16 inch in diameter, and if you are using 1/6-inch pins, you can align to the bottom edge of the lug. If you’re using 3/32 pins you would have to move it down. A pencil line is then made on the top barrel flat. It is a really good idea to put a sharpie mark on the edge of the square’s head to reference which side was lined up against the pencil line. The stock is then attached to the barrel. Hold the square’s sharpie marked edge firmly against the pencil line, the point of the pin is then pressed into the stock to mark the wood (Mark that point on the wood with a pencil to make visible). Then the square is placed on the other side of stock, being careful to use the sharpie marked side against the pencil line and mark the stock (if drilling from both sides). The marked holes on the stock should be slightly counter sunk or pressed to prevent wood tear-out.
The following picture shows the attachment locating the lug pin hole and ready to put a pencil line on the barrel. The next step is to put the stock on the barrel and mark the stock for drilling. The next picture shows the barrel ready for marking.

C-Clamp Drill Jig
A past customer has asked for a Drill Guide that would clamp to the object being drilled. Their feeling was that it allows more precision alignment when drilling. I was and am indifferent to the clamp feature but, it has proven popular.
The latest variation of the C-Clamp jig with solid steel C frame uses a custom knurled aluminum knob and high strength steel thread rod.

Notice the alignment of drill bit to point. The C-Clamp jig allows the jig to be lightly clamped into the slightly pressed marks to what is being drilled. A couple examples are shown below. 1/16 and #29 holes drilled can be then enlarged with a larger bit e.g., 10-32 tang screw or 3/32 lug pin holes, and clearance holes for screws. This will save having to have a drill guide for every bit used. The jig can be used for drilling other holes such as the tang.
(It is best not to completely drill through from one side and drill into screw. Drill almost through then stop and reverse the jig and drill from the other side). This will also prevent tear out of the stock. If your careful about tear out you can completely drill through in one go.

The jig includes a 1/16" conical guide and a #29 (8-32) guide that will allow good visual alignment and clamping prior to drilling. The jig does not include 3 inch 1/16-inch drill bits shown in pictures that are required. Sources for 3 inch 1/16 bits include McMaster Carr part number 29315A116 and Drills and Cutters part number DWDTL1/16. These tools are manually machined by me in my basement workshop.
