I picked up an old Diston and Sons rip saw a few months ago but haven’t need to do any large work with it yet. I did try to test cut the saw and found it to be impossible. Last night I bit the bullet and got out the saw sharpening equipment. I started by jointing the teeth. I couldn’t believe how far out some of them were and was begining to wonder if I would ever get a flat spot on all of them. I did finally get there and then I checked the tooth line with a straight edge. Fortunatly the saw was slightly breasted and I didn’t have to do anything else to it. I proceded to sharpen all of the teeth which went along nicely but a bit slow. The hieght I was working at was not ideal either and about half way through I could feel it in my back but I got it finished. A quick look down the saw confirmed that there was still plenty of set in the saw so I went for a test cut. Here is where I was surprised. Even with the saw sharp I could not saw a line without the saw binding in the cut. I wasn’t sure what was wrong until I looked at the side of the blade and saw rust streaks that had been rubbed fresh by the wood. A quick sanding and buffing with some steel wool and a coat of paste wax on the blade and it was time for a second go at it. This time the saw melted through the board. I’m thrilled to finally have a functioning alternative to the table saw and can’t wait for a project that I can use this saw for.

Nice to be able to pick up and older tool, spend a little time on it, and have a wonderful reward when it works
like it was meant to. To me these tools are a permanent part of my workshop that reward me by being there
and getting to take them down and occasionally use them. Thank you for sharing.

Good one Mike. First project on the list is a good sawbench if you don’t have one already. They make ripping a bit more fun.

Thanks for the comments. Swirt, that is exactly what my next project is. My wife wants a new coffee table and I told her she can have it right after I build my sawbench, if she wants drawers in it then I have to build a Roubo twin screw vise like the one in the newest Popular Woodworking Magazine, gotta have something better than F-clamps to hold a board when cutting dovetails!

Bravo on the saw work. I have several old handsaws that work great. I’ve been wanting to try to sharpen one, but so far haven’t had the time to practice. Also, there’s an older guy near to me that still does sharpening & works cheap, so I haven’t been motivated enough yet…but I will.

Mike, I know you are looking for a reason/excuse to build the Roubo twinscrew vise, but just in case you need to make dovetails before you have a chance to build one, here is alternative I use.

Tom, it is actually really easy to sharpen the saws, I grew up sharpening chain saws so wasn’t too intimidated by the hole thing and it was a pretty easy transition. I think a coarse rip saw is the best place to start when you decide to take the plunge.

Swirt, that is a great idea with the clamps. I tried to thread some wood this weekend with some machine taps I had available and the threading of the dowel did not work out at all for me. The tapping part went ok but it looks like I would have to buy or build a thread box to thread the rod. I think your idea will be my method of choice for awhile now. Thanks for the tip.
