DW735 extension table adjustment question

[Bill Fitch]

All you guys with DW735 planers and the extension tables, did you adjust them after installation or leave them as delivered? The way mine came, they both slope upward quite a bit and are not parallel to the planer bed at all. I would guess the outside edge is about 1/4" higher than the bed. The instructions do not even mention adjustment, but I can see the screws and slots on the side of the tables.

What is the best adjustment? Should I just make them parallel to the bed, or raise them just a tad?

Any guidence is much appreciated.

No expert here and I don't remember why or how much, but mine are adjusted slightly higher to help eliminate snipe on the ends of boards. 1/4" seems like a lot, I would adjust them slightly to where you get no snipe. this may be flat, but as I said, I adjusted mine slightly higher. Sorry I can't remeber if that was in the instructions or I got it somewhere else.

I would say, if you are happy with the results that you are getting right now, then dont mess with them. If you are getting a lot of snipe then you may need to adjust them.

The rule of thumb is to adjust the outer edges so a straight edge across the bed is raised the thickness of a penny.

Mine are adjusted up about a little less than 1/8" (works well for both narrow and 13" wide boards). When working with long heavy boards, very dense stock, or planer sleds I will adjust up till the snipe goes away or is acceptable.

Nice video That was postd before. Just go to the one "beat planer snipe"

The video explains it. My extensions wouldn't have provided any support without adjustment if I would have left them at the factory setting.

I got my extensions a week or so ago and put them on. I then adjusted them in the same fashion as the video. I was still getting leading edge snipe about 1 1/2 inches into the leading edge. I also ramped up the in and out feed to try and counter this. I am still getting noticeable snip on that leading edge. My next check was to see if the bed was flat under the blade portion or if there were a ripple in the bed that causes it to raise up inside while cutting. I haven't gotten any further at this time due to time constraints. Is there something I am missing?

[Larry Frank]

I have the infeed side almost flat and the outfeed end up the thickness of a penny or so. With this arrangement, I am getting very little snipe. I should mention that I usually do not plane boards any longer than 4 feet or so and that would effect the snipe. With a longer board, you have a lot of board(weight) hanging out the end and could result in snipe.

Thanks all. I will dial it in and make sawdust this weekend!

Definitely adjust them properly. My dad's 735 does well at the penny height Myk describes. My 734 gives no snipe at all but, a straight edge liad through the machine and resting on the outer edge of each table sets about 1/8" off the platen.
