Hi Gang.

So, I’m not wildly enamored with my Veritas 14tpi dovetail saw. It cuts fast but doesn’t leave clean edges.

I’m tempted to go to a Japanese Dozuki pull saw. I’ve used Japanese Ryoba before and like them a lot. I find the pull easier to control than the push.
But, I am concerned about the coping saw not fitting into the narrow slot?
Not finding a lot of info about this in my research.

For those of you who use Dozuki saws to cut dovetails, what is your method for cutting out the waste?
Special blades in a fret saw? Special blades in a coping saw?

Thanks.

I use a a dozuki and my coping saw doesn’t have any difficulties getting into the waste at all. I start at the top right corner of my cut, saw on a diagonal to the bottom left, and then I saw straight across for the second part of the waste.

You can always use a fret saw, it is what I use. You don’t need the expensive ones just twist the blade a little with a pair of needle nose pliers and you are good to go.

I bought some special thin blades from Bob’s blades, but I find it too easy to accidentally damage the sidewalks. I now use the fret saw as Kaleb described. Much easier since it takes the consternation away of damaging the sidewall when starting the cut.

Some dovetailers use a very sharp chisel to clean out the waste.

David, can you explain the fret saw thing? What’s different about it/the blade that makes it work better? Or do you just mean the diagonal cut, then cut across is what helps?

Paul Sellers has some video either on Youtube or if you do the free signup for his Masterclass website that shows the chopping method that Ron mentioned. I can’t remember exactly which of his videos show it, but I know at least the dovetail caddy series on the Masterclass site has it.

I originally purchased thinner fret saw blades so I could fit the saw in the kerf left by my dozuki, but I found it too easy to damage the sidewalls of the dovetails when starting the cut. The thinner fret blades (purchased at bensscrollsaw.com) worked fine, but just required too much concentration and probably skill for my use. I found it much easier to use the fret saw and first make a diagonal cut as Kaleb described, then make the horizontal cut to remove the bulk of the waste. Does not really take much additional time at all.

Before using a fret saw, I would chisel the waste out, but when I started using narrow pins, chiseling was more difficult due to the lack of space for the waste to clear. I use a lot of softer woods, so binding the waste would also damage the dovetail sidewalls.

I do not understand the issue with your current saw. If you cut dovetails the way I was taught, the rough back edge will never be seen when the joint is assembled??

hi ron.
yes, the rough cut edge isn’t seen, except it’s rough and therefor not as straight a line and therefor harder to achieve a real nice joint. splitting hairs, maybe, but still.

Have your say...
