Default The correct drop leaf router bit set

I'd like to be sure I select the correct drop leaf router bit set. I see one from Freud for tables with a 3/4" top. The table I'm planning has a 1" top. Can any one recommend a solution? Thanks!

I think and someone correct me if I'm wrong but you can make your own set for almost any thickness material by combining matching cove and roundover bits.

I don't recall seeing any bit sets for 1" material so I can't help you there, but if you want to try and get a set to work you also might have to pick out the hinges and how they will mount. I can try and help if you like but it might be better to have someone who has already done this to advise you. Let me know.

A quick follow up, I checked a half dozen catalogs I have sitting around and none had a set for anything but 3/4" tops.

I do belive to achive your drop leaf . That you need a drop leaf hindge, it will have an off center hindge whitch is about a three to one ratio. This hindge when correctly placed will make the lesf flush and not expose the hindge.

Yes and hinges come in a surface mount and an inset and they do make a difference in the design.

To get the right support you need a coving bit and a roundover bit, both with the same radius.
Rounding over bit on the main table with the coving bit on the drop leaf.
This will provide support along the whole table length.
The actual radius is not so important.
Just make sure that both bits are the same radius.
Take a little off with each pass until the 2 sides are level when joined together.
Using drop leaf hinges correctly fitted completes the job.

Just tried putting 3/4" roundover and cove for the drop leaf table on a 1" top thickness. When cutting the cove we need to set the fence distance to match the bearing and then raise the router bit in about three different exposures of the cove then cut. The height measurements are raised in small cuts until they match the round over cut.

Steps to doing the cuts are as follows:
1) Make sure the table and leaf sections are exactly the same thickness see photo roundmaterial.jpg

2) Set up the roundover bit to have approx. 1/8" of the profile line exposed. Cut the roundover on a scrap piece and the main table, see photo roundoversetup.jpg and roundovercut.jpg

3) Set up the cove bit to match the roundover cut on the main table. See photo roundovermargin.jpg, roundcovesetup.jpg and roundcovesetup1.jpg

4) If the cove needs to be cut in smaller cuts you can raise the cove into 1/4 position and cut then raise and put into 1/2 position then cut etc. Remember you can always take another cut but you can't add material back on...SO be sure to be careful to get the pieces to match. See roundfinishcut.jpg

That's how we do it.

Can we go a step further on this subject?

I took a few minutes to draw the instructions as you gave them then added hinges. Please see attached 1 and 2. (1 looks OK, 2 looks like it has problems)

Since the pivot point moves depending on the location of the hinge how do you adjust the cuts to be able to get a correct rule joint, that being; fitting when up, hiding the “space” when down and not a 1/8” gap in the horizontal direction?

I have done “one” of these joints before (a number of years ago) (on a shaper, I have a matched set of cutters) but followed the directions that came with the hinges and never did understand what I did.

Maybe a full-fledged tip one day soon would help me out?????

I have limited knowledge on the installation of the rule joint hardware so maybe we can feature this tip on the email blast and get a good discussion going. The email is going out on Thursday.

Smile The best help I've ever received!

I've got to tell you I am thoroughly blown away by your helpful response. Complete with JPGs!!!!! The only thing you could do better is to fly to Massachusetts and do the routing for me.

THANKS AGAIN!!!!!!!!!!!!!!!
