 So yesterday we took this test piece of plywood that has three different match fit dovetail grooves in it and the idea was to try out different finishes and see which ones might be the best performing when you're trying to use match fit dovetail clamps in match fit dovetail grooves. They're really not match fit dovetail grooves, they're just dovetail grooves. So I had done this section here with Wattco Danish oil. This one happens to be natural color and this is Baltic Berks plywood. I did the middle section with a Varathane ultimate polyurethane that was water based and that was interior and it's matte M-A-T-T-E. And then I did this section over here with 50% boiled linseed oil and 50% paint thinner or mineral spirits. Alright so they've dried overnight and now we're ready to test them to see which one we might want to put on any kind of a jig or in this case a pop-up workbench so that these will slide. So let me get these out of the way. I've got these marked Danish oil, water based polyurethane and boiled linseed oil. So let's see how this clamp slides in the polyurethane. Try to get it in there, try to move it along, jiggle it, push it, you know everything you can. And when I did this, the first coat it boiled up as you know or feathered up because of the water base. So I sanded that off and then I did the second coat and that's what has dried. And I also made sure I wiped as much as I could inside of the groove so that I didn't have buildup of excessive polyurethane in there. And I think maybe the water base swells up the wall of the match fit groove and so you could probably sand it down enough and use a little small chisel and get it working better but that's a lot of work. Let's see if using a different finish is just an easier way. So here's the 50-50 boiled linseed oil. Put that in there and ha ha again. And I'm not playing to the camera here, this is real. This boiled linseed oil, boom, as long as you don't let it build up there too much. And then here's the danish oil. Is that going to stick like the polyurethane? Man, that is, that is cool. Here's the result. Danish oil, Wattco Danish oil, works great. The boiled linseed oil, as long as you make sure you wipe your grooves very well. 50-50 mix, that works great. So just decide which look you like the best, which one, this is a little rougher and as you know workbench tops are not supposed to be sliding around a lot. I'm going to use the danish oil but then I'm going to sand it when I'm through on the very top to rough it up a little bit so that I don't have things slide too much on my workbench. That is a small workshop guys test of what I'm going to use in the future for my match fit dovetail clamp jigs of various types. I hope you found that useful.
