ButterFly Bits

How to use and make butterfly splines on your the router table.
Note** make the spline 1 1/2" to 2" tall, then cut off the scap to get the
1 3/16" tall spline,you need the sq.edge at the top of the spline to have something to hold on to when you make it and to ride against the fence.

I should NOTE****
You can use a 1/2" standard 14deg. dovetail bit but the setup is a hard one and the splines will snap because the center point of the spline is only 3/8" wide.
You can also use the ButteryFly/Dovetail bits on picture frames (on a 45deg. setup) but you will need to make a jig like the one Bob & Rick used .
That's to say a Sandwich type jig, 2 parts cut on 45deg. with the picture frame in the center, then with a clmp to hold them as one and then pass it over the dovetail bit.

Bj, Shouldn’t the Diameter /width of the spline = the dovetail bit Diameter/width?
I just got to find me few of those none feather boards.

Hi Router

You lost me ?
They are both 1", the spline and the dovetail bit. (in width at the big ends)
"feather boards" = easy to make with a bit of hardwood.

That's what I was getting at, couldn't tell from the pic if they were the same
width at the big ends.

I guess I could try it with jigsaw. or cut the pattern and then use a router.
I'm also thinking about wheel type none feather boards, what you think?

Hi Router
I have tried many,many feather boards and the one in the snapshots (Oak-Park type) work for so many tools in my shop,they are great because you can load them up so to speak.
From 1/2" to 3" of load presser with out snaping the stock,great tools for the shop.
I also use them for bench dogs,short ones about 2" to 3" long.

Jig saw one out and use it for a pat. and then set the flush trim in the router and made two or 3 .
Need to watch the grain,rib out, uphill thing.
