Holy COW! I just looked at the date stamp of my last reply in this thread and realized I had allowed this project to languish for almost TWO YEARS!
Over the past few months I had some time to catch up on my backlog of projects and these saw plates were just sitting there collecting dust. I had purchased a bunch of slitting saws a year ago and just never got around to trying them out. Until about 2 weeks ago!
I installed the 1/2 dia arbor in my router table and then set the speed to the slowest it could manage.
I used a piece of scrap to test it and was very pleased with how EASY it cut. There was no pulling, no hesitation, NADA! With that test completed I turned my attention towards making a set of handles from Walnut (since I have a bunch laying around). My thought was to shape the handles to the point where they were ready to get the saw slit cut. Then I'd test out the slitting saw. If I screwed up (again!) it'd only be with some walnut. Not the rosewood, jatoba or BE maple I was planning to use!
So I surfaced the wood to a tad over about 1" (I like it thick to start when making full sized handles. Plus, I have big hands and prefer bit thicker handle) and then stuck some saw handle templates to it.
After I cut out the profile I moved to the router table.
I installed a 0.042" thk slitting saw into the arbor and set the height to the halfway mark I had scored on the handle. As with the test cut, I turned the variable speed setting to it's lowest. Keeping my hands well away from the spinning blade, I made the cut in about 30 seconds. It went so well I had to check and make sure I actually cut the wood!
The end result: a PERFECTLY centered cut!
Now as you can see, the slitting saw is only about 2" maybe 2 1/2" in diameter. And the arbor takes up a good bit of that. So there is NO way I'm going to be able to make the complete cut this way. So it was necessary for me to clamp the saw in my end vise and use a 0.025" thk back saw filed to about 13ppi Rip to complete the cut. The cut made with the slitting saw guided my hand saw just like I wanted. I got a nice straight cut. I then followed up with a .042" thk back saw filed to 12ppi rip and opened the cut up a tad.
But the real proof is in the fitting.
Here's the Crosscut Saw Handle and saw plate
And here is the Rip Saw Handle and saw plate
They came out so good I may continue with the shaping process
The cross cut has a bit of a cosmetic error near the top. But I could cut a piece of walnut veneer and glue it there to hide it. The Rip handle came out just dandy.
Edit to add: Almost forgot to post a gloat here. On Saturday I was visiting a machine shop and noticed that they had a bunch of granite laying about. I asked if I could buy some of the cut offs and was told I could take (for free!!) as much as I could carry. My buddy and I each got a kitchen sink cut out sized piece of granite (25" x 15"). This will surely come in handy for flattening irons and such. But darn, they are heavy!
