I had a piece of 3/4 inch MDF that I had cut for a new drill press table and need to take off about 1/16 of an inch on one side.
Now normally I would have just run this though the TS but I thought now that I have my micro adjuster done and on the router table this would be a good time to try it.
I put in a 3/4 straight bit, lock one side of the fence and the with the micro adjuster adjusted the fence back 1/16 of an inch. It really worked great, 1/16 spot on with just a roll of the wheel of the adjuster.
Had a piece of scrap MDF to make a test cut and it was going just great until I came to the end of the board and the board jumped into the bit about 1/16 of an inch.
I thought, the fences must not be aligned together, the one has to be out a little more then the other one. I got my straight edge out and checked them. They sure seemed spot on to me. I ran the straight edge across the fences and I could feel not dip when I left the right fence.
I just must have pushed the board or something to cause it to dip like that. So I grabbed the scrap and ran it though again, all was well until the last inch and it dipped in again and made another indent about 1/16th of an inch.
Now I am just a little unhappy with the Jessem table and fence, what is the problem here. I got out the digital dial indicator, made a mount that would fit in the track and reach the fence right were it was setting. I wanted to see just what was going on with the fence right were it was. Got the little bracket done, only took about 30 min, to get a nice little maple mount for the dial indicator done and mounted in the track of the table. Now there is my problem, the fence is off and not square. Now at this point I am into this 1/16 cut about an hour.
Ok, I worked until the fence was .001 square end to end and the bit was 1/16 out from the fence, this was not to hard with the micro adjuster on each end of the fence, now I am ready to make this cut.
Placed my scrap on the table and run it thought.... now what in the #$@!# is going on, it did it again, about a 1 inch long dip in the board 1/16 inches deep.
At this point I am into the 1/16 cut for about an hour and a half, I think I will just use the TS and get it over with, this is not working and I am going to have to find the reason but I want to get on with the project. Went to the TC, set the fence up so as to cut a 1/16th off one side put the board on the table to check it.
Then just like someone hit me up side the head with a 2x4 (which I needed) I knew what my problem was, I forgot to shim the out-feed fence on the router table.
So now I have to do it on the router table, just have to.
Put a shim under the out-feed fence adjusted the fence with the macro adjuster and made a perfect cut the first time.
Now it only took about 2 hours to trim 1/16th of an inch off an 18 inch piece of MDF.
Some times I wonder what in the world am I doing in a working shop....
