I have the type where the slotting blades mount on a shaft with a bearing and retaining nut on top. My question is can I remove the bearing and Safely use a 1/16 " slotting cutter for a greater depth of cut? Removing the bearing gets me an extra 5mm of cutting depth to reach through the bottom of my spline sled. Also can I use cheap Home Depot washers to fill the bearing space so the nut applies full pressure to the 1/16" blade. My intention is to use this on a router table and set the fence carefully to avoid my work piece contacting the actual router bit shaft. I'm using a small shop built sled for cutting splines on box corners similar to one typically used on a tablesaw but flipping it on its side so the sled rides against the fence. The boxes are small so a 1/16" spline looks better.
As a footnote I was going to do this on my saw stop with the thin kerf 7 1/4 inch sawblade but I can't figure out how to disable the blade sensor with the smaller diameter blade, The saw stop won't let me.
Thanks for your help.
