Reply to "New Layout vs. Old (Build Thread)"

3 down and only 8 more to go... OSB sheets that is. I got three sheets laid out and cut today. I tried the improved method of using a previously cut piece as a curve template for the next sheet thus avoiding the off-sheet center-point problem. To make it more stable, I hammered in some small nails at the apexes and just bumped the template against them to make the curve. It worked nicely and made it easy for me to do the curves without a helper.

In addition, it was gratifying to see how closely the actual layout conforms to the computer design. Here's a close up of the template after being bumped up against the pins, and how close the curve comes to the sheet edge. Above it is the drawing with the coordinates. Note that the edge of the piece in the drawing touches the edge of the sheet, just as the real one does. It's within a 1/4". The sharpie that I'm using makes a line an 1/8" wide so being within a quarter inch is quite acceptable.

Perfect curve fit

Here's the third sheet completely laid out prior to cutting. It's a relief to know that I'm not making fine furniture. Any blemishes, or not-so-hot cutting will ultimately be concealed under layers of track, roadbed, ballast, paint, ground cover, foliage, etc.

And here's a closer look.

Now for some fun... I'm working with the grandkids to build a large jigsaw puzzle on the floor of all the sub-roadbed pieces to get an idea of how it all fits in the room compared to all the plans. My 10 year-old said it more "sawing than jigging".

As the time goes on this picture will fill up. Then all I have to do is build the trusses that will hold it all up. The frame construction is more fun than cutting out all these slices.

Since I already have a Visio drawing showing the layout placed in the room, this "puzzle building exercise" will give me another reality check. "Does it really fit with the clearances I need." I can fix it at this stage more easily than if the framing was started.

I have work tomorrow. Will get back to cuttery on Wednesday. At the rate I'm working all the pieces will be cut by the end of next week.
