Frame Saw
 | ||
I made this saw to help with resawing wood. It is very good at rip cutting and other long cuts. The frame is made from Hard Maple. And the blade is cut from a 5tpi bandsaw blade. The saw is 31" long by 23" wide. The blade is 27" long with 9" clearance on either side.

| I cut four peices about 30 inches long, 1.5 inchs wide from some 8/4 Hard Maple. These were planed until they were either 1 inch thick by 2 inches, or 1 1/4 inches by 2 inches. | |
| The thicker pieces were used for the ends and the thinner ones for the supports. They probably do not need to be so thick, but I think it looks better. | |
| Motis and tenon joints where cut in the arms and strechers. These provide a nice strong simple joint. Since all the force is from the blade tension, there is not even a need to glue them. | |

| I cut blade guides out of scraps. These I grooved with a V shape and then set into the supports about 1/4 inch. These will hold the blade and keep it from spinning. | |
| Cutouts are centered, and the peices will be glued in place. | |
| After glue up, a hole is drilled through the center of the block to hold threaded rod. Also a backsaw was used to cut a notch across the block for the blade to slip into. | |
| Blade holders. I don't have any pictures of making these. Basic proceedure is to use a hack saw to cut a 3/4 to 1 inch slot in middle of some threaded rod. Next take a drill bit just smaller then the size of screw you will be using (in my case 3/8" rod with 6-32 screw). Next take a bit just larger then screw and drill out top half of hole. Lastly take a tap and thread bottom hole to take screw. I also flattened the side of the rod to better support the screw. The thumb screw is used for tightening the blade. | |
| All put together. | |

| Here you can see how the blade fits into the guide and does keeps it from twisting. | |

| After I was finished I took my spokeshave and carved some handles into and and took edges off arms. This makes it easier to hold. | |
