I started making the grip cap on the lathe with a piece of 2 inch steel.  I turned a shaft to 5/8 inch, leaving the thickness (.105) as a 2 inch flange that will end up as the cap.

I was distracted while turning this and completely forgot to take pictures while in the lathe, but this first photo is of the part after it came out of the lathe and some work had been done in the mill.  You can see what will be the parting line that will become the bottom of the cap.  The drawing just above the part shows this.  I have also machined a flat on each side that will align with the long side of the ellipse.

Photo 2. While in the lathe I put a small center in the top of the cap to assist in laying it out.  The outside rim is the 2 inch diameter of the original steel.  The outside drawn ring references the long side of the ellipse, and the small ring the short side.  I used a sharp scribe, in the mill, to mark the long and short side, forming an elongated cross.

Photo3. The radial lines are marked at 30 degrees then intersecting line marked, these intersecting lines can be see.  These lines are then used to hand draw the ellipse as shown.  At this point I had started machining the cap, making it square and to the line.

Photo 4. From there I just picked away at it until I had the rough shape of the cap.

Photo 5.  All roughed out.  Now I will attack it with a file and finish to shape.  Notice I didn't say to the line, the line was not good enough to finish the shaping, I finished it by eye and using the line only as a reference.

The rest of these pictures are different views of the finished grip cap.

Not trying to bore you all with this cap but here are some pictures of the completed and installed cap with the screw.  I'm not going to get into it here but the cap has ended up being part of the equation to hold the stock wood to the frame properly.....this I did not expect!

I think the pictures explain them selves.

Bob , you don't have to worry about boring any of us, me especially!  I really enjoy seeing the problem solving that goes on in a build like yours.  Thanks for all the great pictures and explanations.  I also enjoyed the write ups you have done for the Journal.

Regards,
Joe

Thanks Joe and Greg, at time I do wonder if I’m getting into too much detail and losing folks interest.  But, I keep plugging along hoping it gives other the initiative to go after a project they have been hesitant to  continue or start.   

Greg, it does take work to post these, but I do have the process down and can get it done fairly quickly.

Greg, I plan on being at the show with this build.  If there is room to bring it, there will be an original there to compare my work too.  I may  also bring the Remington #7 so you guys can see the actual gun rather than just pictures.
Bob

I really enjoy following your build posts Bobw. I am not a machinist so it’s out of my realm, but I do admire those with the talent to carve metal, whether it be an artistic machinist or engraver. I enjoy bringing old rusted rifles back to life, as in polishing, filing, rust bluing and all the file work to make a new small part, but machining is a talent of its own! Keep up the great work.

I hope Greg and Bob and others who make guns and parts will continue to do so and post their efforts.  I appreciate that it takes a lot of effort but it is the best part of the forum for me!
