5:1 Oak and brass dovetail marker: I sense trouble ahead!

I made this on the spur of a few moments, basically because I wanted to and I could do it. The wood is a scrap piece of oak which was about the size I needed. I cut a shallow dado in the wood with my table saw to accept the brass and (hopefully) hold it straight. 1 brass nail holds the brass ‘blade’ in place along with some epoxy. The off center nail is…my trademark, yeah, it’s my trademark!

I was aiming for a 1:8 but I goofed up my angle, forgetting how to actually measure it. I later correctly measured the angle using my bevel square to determine what I had actually created. I plan on making another, truly at 1:8 with darker wood to tell them apart. I could post a step by step for that one.

So, are there dovetails in my future? Well, somewhere in my future, but not right away! I just like making tools, especially ones with brass.

The wood measures about 1/2×1/2×3 inches. The brass is 1/2×2-3/4×1/16 inch. The wood is finished with boiled linseed oil.

Nicely crafted, Dave. Even if it’s not what you started out to make. ;-)

Thanks. From what I’ve seen ‘they’ say you need two pitches of angle, one for hard woods and one for soft woods. I dunno, but I’m sure I can find a small bit of mohogany to make the 8:1. These markers seem to be the grease box of dovetailing. here’s a bunch of different designs possible.

Yea, the “experts” say to use a 6 : 1 angle for softwoods, and a 8 : 1 for hardwoods. I made one of these, using a 7 : 1 as a compromise, because I can’t cut a straight line anyway, and all of my projects have remained intact to date. When I cut dovetails, the angles on any one tail aren’t even the same on both sides. It can hardly be noticed, ( I only notice after cutting and leaving various parts of the layout line ) but if it is ever brought to my attention by somebody, I’ll just say that proves it is hand made.

You would probably find that our ancestor’s dovetail joints are far from uniform in many cases. as long as they sit well, all’s well.

I tried to cut some doves tails last week but one of the birds managed to latch on to me in the you know where so I gave the idea away!

I am still keen but do not understand how you device works, maybe it will stop me from getting nipped again.

Rob, I think your material is too fresh. You might try kiln drying it for 20 minutes on 350 F. Then cut it with a sharp knife.

This is a nice simple and practical shop built tool. Every woodworker should have one in the shop. Nice work.
