Tried making v-groove box

[LCHIEN]

Saw people making boxes using v-groove bits that cut almost all the way through.
tried it on a small scrap. Like i thought its really hard to control that last bit of thickness.

Once cut and taped, and you cut the corners off, you glue, fold and clamp the sides up. This was some 1/4" stock.

Anyone have any experience with this?


Here's a short video

I have seen a similar video before, but it was for making a box. I didn't think of it for making a frame. Still, for making a box, I would think it takes some practice and using quality plywood or some hard to find straight grain thin boards.

Thanks for posting this.

wasn't meant to be a frame, just a very short sided box. I was just experimenting with a small scrap to see what the experience would be if I scaled it up.

Easy-to-Make Plywood Drawers and Trays

Rout V-grooves in a plywood panel and fold up the edges to form a box.

Fine Woodworking #259 Jan/Feb 2017



I needed a dozen small trays to hold hardware. I wanted them strong, but quick and easy to make. Then I remembered a technique Roy Underhill used on The Woodwright’s Shop years ago. He cut V-shaped grooves in a wood panel by hand, just short of breaking through the opposite side, and folded up the edges of the panel to form a box. I used a router fitted with a V-groove bit and traded the solid wood for plywood.

To size the initial panel, start with the length and width of the finished tray and add the height of the sides to all four edges. Then put the V-groove bit in the router and set the fence so that the distance to the point of the bit is the height of the box sides. Simply run all four panel edges against the fence. Do the first box in multiple passes, creeping up to the perfect depth of cut for easy folding without breaking. You can make multiple boxes with the same setup, as long as you use plywood from the same panel.



Use a sharp knife to remove the squares at the corners. Then spread glue in the grooves and fold the sides up to meet each other. I use blue tape to hold the sides together while I put a band clamp around them and tighten it. To avoid getting breakage at the folds, cover the back of the V-grooves with blue tape before folding them.
