« Part 5: 45 degree jig Part 6 of Handy tools series no next part

While building my box for the swap, I wanted to put some banding around the top of the box. This would mean cutting the ends of the banding at 67.5 degrees (90 – 22.5), and I figured I was unlikely to get that uniform with a saw, so I built a guillotine for cutting that angle. I used a couple scraps from around the shop, a hinge from the hardware store, and the blade from a utility knife.

The results were good enough that I used them on the top of my box straight off the guillotine.

It’s a useful tool, and now hangs on the wall, waiting for my next octagonal project. If I ever do a hexagonal box, I’ll build one for cutting 60 degree angles.

You’re welcome, Gene. It took me an hour or two to build it, but once I did, cutting the pieces of banding went fast. And taking a 1/32” off the end after I’d made my initial cut too long wasn’t too hard. Well worth the time spent building the tool.

Thanks, Daves. Think I stole the idea from one of Paul ( shipwright’s ) blog posts, but I’m not certain.

Dave the minute I saw it I thought of Pauls how2 as I had questions about it’s construction.
It’s so cool when we need something to get a job done and can look back at all the many tips that are offered here on LJ’s to get the job done.
We may no even remember where the hint came from but the seed is there to be used.

Exactly. I may not ever build models like you do, but I’ve had a couple “ah-hah!” moments while reading your construction blogs and applied those tricks to my world. You use a disc sander to sneak up on a perfect fit. I use a block plane or a spokeshave in similar cases. The idea of switching tools to something that offers more precision was helpful.

Dave ,
Nice work,
Your Jig is certainly producing unexpected results, I did not think you could use them straight up without preparing the edges after cutting.
