Straight Stock and Pitch

[Austin W Hogan]

A dry wall square is not as elegant as a combo gauge, but it will give you all the numbers.

PS As I remember from analyzing that machine inletted but unfinished DHE stock for DGJ. pitch is established for a Parker stock when the blank is headed up, and the butt plate inletted.

Robin, if you are confused by the different barrel lengths, just measure the pitch from the same point on each gun. It was asked (by Robin) how we are to use this information. Well, I think we will use the information derived from a gun that feels good and that we shoot well to determine the pitch we would prefer on the next gun we choose to modify. However, that isn't neccesarily true because I own very comfortable guns that have zero pitch and I own very comfortable guns that have three inches of pitch. The only modification I have ever made to the butt of any gun to make it shoot better is to put some sticky stuff on it to keep it from slipping on the second shot. Any deficiency of length or pitch I have taken care of by adjusting my shooting style. Unlike Chuck, I have never had a competition gun that needed an adjustment in pitch to compensate for excessive recoil or cheek slap. Either I am lucky or all of my guns have similar pitch. Actually, I'm just fooling with you because all of my comp guns seem to have about 1 to 2 inches of pitch and all feel the same.

Here is the pitch analysis that I used in the DGJ stock dimension article.

Best, Austin

This is an excel file, which will not upload. The data came from measurements and dimensions by DuBray in the order books. Straight grip stocks varied from 1 1/2 to 3 1/2 inches pitch. I have the full table that includes drop, pull , inches and degrees pitch, but it is copyright DGJ. It can be looked up or perhaps I can find a way to publish one of the the preliminary data sets I used in the analysis.

Here is a frequency analysis of 33 Parkers that I did before writing the DGJ article. The numbers in the bottom table are the number of guns with the pitch measured by the stand against the wall method.
An aside note; the PH shown near here as an example of straight grip checking is the gun with the least pitch, as measured this way. It is the only straight grip gun that I can use to shoot skeet five stand or sporting from an unmounted gun at the call.

I will contact Robin about putting the dimensions table on the FAQ.

Best, Austin

The table is too long for doc files; I'll make another try

Nothing like starting off the day by outsmarting a computer. Maybe this version will be acceptable.

Austin,

That is great information. My crude conclusion that the more drop a Parker has the moare pitch it will have follows what your data shows. Do you recall what issue DGJ your artical is in? Would you give me the stock DAH, DAC, length and pitch of your PH?

Thanks, Harry

Now that indeed is good news. I hadn't thought about the door jamb method with a hammer gun, as all of my doubles are hammerless- good point--

What makes a drywall square, framing square etc work is the Pythagorean Theorum-- but here's a puzzlement, at least to me-- a roof with a 12/12 pitch is a 45% roof-- half of 45% is 22.5%, and half of 12 is 6-- But= when you want to step off common rafters for a 22.5% roof it is a 5/12 (unless it is a hip, then it goes to 5/17)-- huum- hey, that's just the way it works I guess.
