[quote name=\"TheJackal\"]Slick idea.

While you have it jigged up and aligned you could also drill and tap the 8 holes used to bolt the cam box to the breech casing.  Once the cam halves are split it is abit more difficult to ensure these holes are in the correct location.  Just and idea.  :)[/quote]

[quote name=\"nitewatchman\"]Outstanding idea, beats the way I was going to approach it.

If I get my box cam done before you guys are ready to do yours you are welcome to use the fixture, as long as you don\'t mind paying shipping. That goes for anyone else that may need it.

I finished my crank arm and it\'s attachment to the crank shaft, milled the gear block, and line reamed the journals for the crank shaft. I opted for a different approach for attaching the arm than the hex drive suggested in the prints, and I\'ll post a picture of my set-up when I get batteries for my camera.  :D

Thanks for the offer on the fixture, but I bought a box cam semi finished from cutter.  The hardest part, the cam slot, is already machined.  I just need to do the rest of the machining to it but have been busy machining barrels so that will have to wait for abit.

Yours is coming along nicely though.

I worked on oscillator parts over the weekend. I\'m just about done, except for the cam. I\'m thinking about making it in three pieces. Does anyone have any tips they\'d like to share on making the cam?


I made the lock body from one piece of brass rather than the silver soldered arrangement in the plans. I just undercut the boss with the 5/16\"-24 hole already drilled and tapped with a 1/16\" slitting saw, and then removed excess material with a sanding belt until it cleared the tube.
 Kind of crude I know, but I like it better than the drawing, and it is hidden when assembled. The way it\'s drawn you\'d need a .016 solder bridge for the hole to be in the correct location.

I went with three pieces pinned together for the oscillator cam. Made it pretty easy to machine, but I did have to do some hand blending to get a .250 pin to pass through the corners of the cam slot.

Looks great.  I don\'t plan to do the oscillator version but looking at how well your\'s looks I might reconsider.

 I hadn\'t planned on it either, in fact I\'d already machined the ball socket for the non-oscillating version. It was going to have a tripod when I started also, but now I plan on a carriage.
Meanwhile, the breechplate is done.

I\'ve been messing with different shapes for the crank handle, and I think I\'ve settled on this shape. It sure beats the plane Jane handle in the drawings.

Decided to go with a lever rather than a knob for the bolt extractor.

your brass parts look sharp. i just got my barrels back from being chromed and polished brass and chrome will look sweet. what are you using to polish your brass? any special compounds or just paper?

Post some pics of your barrels! I used a cloth wheel on a bench grinder, with some brown rouge I think I got at Harbor Frieght.

Cool, looking forward to the pics. I hadn\'t considered chrome plating, I was leaning towards using SS tubing and polishing the barrels. If you don\'t mind me asking, what was the cost for the plating, and who did the work?

I milled the frame rails the other day. Once the angles were cut they bowed approx. .04\" low in the center. I straightened them within .010 and then took a skim cut off of the top to get the top surfaces nice and flat. Problem is, when I cut the ejection slot in the left rail it bowed the other way. I got it straightened back out without too much trouble though.
If anyone else is considering brass frame rails you may want to have the bar stock stress releived before you machine them.
