I cannot figure out how to make this dado the correct depth without tearing up my coping Sled

I know to use a shim under the router table fence that is the same thickness as the Coping Sled base. No problem there. Although the photos do not show the shim, they do show a small strip on the sled base up against the fence that I “removed” before I knew about shims.

Here is my question.

Even if I shim the fence to match the sled base, I still can not lower the bit enough to get the cut depth I want without tearing up the sled base. I just want to make a ¼ dado and I cannot get the bit down that low without tearing up the sled, even with the shim.

The bit is still way too tall to get down that far.

I cannot figure out how to make this dado the correct depth without tearing up my coping sled

I just do not believe the answer is a different bit………shorter. That doesn’t make sense.

There has to be some process or technique that I do not know about.

I have never used a sled before. For years all I used was a big backer board, and occasionally (rarely) double stick tape. Never a problem. But my grand-kids are getting old enough to use some of the tools in the shop, and I didn’t like the idea of them using the router table (on some cuts) so I bought the sled.

Any guidance would be appreciated.

Best……….. Bruce.

do you mean a rabbit? if so you could easily make it on a TS with any old blade just make multiple passes.

Hey Shawn…........

Well, I am making both rabbets and dados….........

And, I do make lots of both on the table saw with a flat top rip blade or my dado stack….........

But, most of all, I am trying to learn how to correctly and competently use the sled on the router table

The only thing that has occurred to me today is putting another board UNDER the piece I want to cut which would raise the wood up to within acceptable adjustments on the router bit.

Thx for responding.

Best…........ Bruce

Can you just raise the workpiece to the desired height by adding some ply/thin strips under it?

Looks like you figured out my solution while I was typing.

That is the only thing I have thought of that would work.

Not too sure how crazy I am about running stacked wood (even well clamped on the sled) through the router, but I sure cannot think of anything else.

Thanks for the response.

A little bit of double faced tape will stop the stack from shifting.

I assume that the sled rides in the t-track on the router table. can the guide be moved on the sled to clear the cutter?? and yes I knoow what assume means. hahahaha

I’d make a sacrificial coping sled for this situation.

Unless, of course, you want to mess up that nice one in the picture.

Have your say...
