Two sided carving

[Jeff_Birt]

I've been searching through past posts trying to gain some insight into two sided carving. I found the biplane files that the CW guys posted, which has carvings on both sides of the planes body but I cannot find an explanation of how the workpiece is registerd when changing sides.

Do you flip the stock about the X-axis and the machine then finds the end and calculates where to start carving?

Jeff,

Since the machine will measure your wood and the first side is cut so the complete wood is still there after it's finished and the reverse side is on the same wood (but on the other side) if you put the wood in properly when it's measured again it'll do the registration for you accurately. It's that accurate a machine. As I've mentioned before, I've stopped the machine in the middle of a project, removed the wood, then put it back and started the project over (too bad you can't jog it to a position and have it pick up again) and the machine did the remeasuring and started carving all over again, except since it was already carved, it went through the steps, yet the bit never did any further cutting; it just moved the sawdust from the previous carve until it got to where I had stopped it, then it continued without a hickup or false move. That's pretty accurate, I'd say.

Thanks Bob, so when you flip the stock over you do so front to back, i.e. the left-right side of the stock are in teh same orientation?

Jeff,

In the software you have an "F" and "B" icon which indicates Front and Back side of your wood project. In either of your sides you also have a center horizontal and vertical guide ... for centering work. Thus on the F side you can Control C (copy) any selection, click on B and then Control V to copy it to the back side, then reverse the image and it'll match the front in reverse. Do your revers design to the requried accuracy and when you save the design you'll also be saving both sides and the machine will automatically register to the wood.

Bob, what I'm asking about is how to flip the wood on the machine.

[BobHill]

Jeff, horizontally. Right to left or left to right will do it.

(edited) And since I failed to mention how that is established (for me) it's left to right as looking directly at the cover and across the way the wood moves.

Thanks, Pkunk.

Jeff, flip it L-R not end for end.

The easiest way I remember is the part/side that is touching the gold guide roller will be flipped so that it is now on top and and farthest away from the guide roller.

Aaron, yours is the only answer that makes any sense to me (a total noobie with the CW). I have a simple carve I'm doing with a piece of custom floor trim between my kitchen and living room with uneven horizontal mating surfaces to the trim. The top of the trim has a "shee-shee, foo-foo" type of pretty top that is a graduated domed effect. HOWEVER COMMA! I'm not as trusting as most and am going to try a super short sample first, as to ascertain just how the opposing side cut is situated on the board. Sure I could just "center both" the damned thing and come out fine, but for future carving, I'd like to know where an off center, two sided carve will place the second side.

Jeff Brit that is a name I have not seen in Years....

The Board Width in Designer is critical in my opinion when you flip the board over. Since the measurement is based on the Brass Roller Edge of the belt.

So what I am saying is the Physical and the Designer Board Width must be the same. Because you are going to Roll or flip the board starting on the back.

I would put your board in the machine and let it measure the width. Even to get it to measure start a project with a bogus width and it will measure it and tell you what it found...

Use that width in Designer.

A test you could do is center a 1/8 inch drill hole on each side of the board offset slightly in X or length.

That would tell you QUICKLY if the machine is going to cut in the center of the board BOTH Sides.
