Default Glue Joint

I am using a Triton router table with a Makita 3612C router and am trying to do a proper glue joint.

I have two questions:
  1. What causes the cut to this: http: // i282.photobucket.com / albums / kk267 / GerhardWessels / Gluejoint.jpg
    (Sorry I can't post URLs yet) This is the SAME cut on the two ends of the stock!
  2. How do I handle stock (say walnut) that is not 100% straight? Pressing down hard on the router table bends it which causes problems too!

Thanks.

First, why are you using stock that is not straight? To get straight stock, you need to joint one side of the board flat and then then run it through your planer to get a board with parallel sides.

First, here's your corrected link
http://i282.photobucket.com/albums/k.../Gluejoint.jpg

Did you not use featherboards? Wood climbed, or the answer to the first question is the issue with your second question....which would mean the wood climbed !

Second question was answered.

Hi Gerhard

I would suggest you view the video below..I would also suggest you use a true and clean 2 x 4 clamped to the fence for a feather board,,most stock is not flat..
The 2 x 4 will hold the stock down all the way through the pass..

MLCS Euro door, door lip, finger pull, drawer lock bits, glue joint router bits

Question #2 technically answered #1. You need to joint your material to get them "straight". You don't necessarily need a jointer, your router table can do this job. Just need a jointer fence and, this can be made quite easily in your own shop.

That's a real nice site. It has lots of bits and video on how to use the bits. Thanks bobj3 for the link.

There ya go.


You'll be hard pressed to find a truly straight board unless you get it the day it comes out of the planner / jointer. Wood moves with moisture in the air.
I'm not saying you have to live with a 1/2" bow or anything, nor am I saying that's a normal warp ( if its anything close to that you are working with ).
Just saying that a little off kilter is normal due to movement cause by moisture. The wood sucks up moisture and swells causing warp, or dries out and shrinks causing warp.
Have you checked your table for flatness, as well as your plate ? Some plates are known to have a crowned area right around the throat which can mess you up real good sometimes. If your table sags and you are working with long stock the same will happen as well.
As well, if the work piece is bowed on the side to be milled by the router and you run it through the same will happen.

You can make a jointer fence quite easily ( as Ken has already mention. )
A jointer fence would be used so that a trim bit with bearing in the router can surface two sides of two separate work pieces so they can be joined together.
You can easily make one by making a traditional L shaped fence with split sacrificial insert boards. then all you have to do is go to Rockler and buy their jointing shim pack for $7.00 and change ( or make your own shims ), loosen the out feed sacrificial insert on the fence, drop a shim behind it, and tighten her back down. Then simply hold a straight edge on the shimmed sacrificial insert and push the fence back up to the bit until the straight edge just moves the bearing while remaining flush on the shimmed side of the fence. Then tighten your fence down and you are good to begin jointing.

Actually, your Triton fence would be ideal to use as is with just a split sacrificial fence and shims as described above.
Then when you are done just pop them off and pop on the one piece straight sacrificial fence again if you like.
