Topic tags/keywords: question plane

I was playing with my Ridgid planer trying to adjust in the in-feed and out-feed tables to reduce the snip.
I found out that the central table the one which cannot be adjusted , is slightly to high.
I removed it but there is not adjustment.
Do you think of anything I could do?
Thank you.

I’m not sure I get you. Why can’t you just adjust the infeed table to match the center?

While leaving the in feed table level with the center table try raising the out feed table slightly or as much as needed to reduce snipe.

I can easily raise the far end of the in feed and out feed tables but not the part closer to the central table( the hinge), which is the part which is too low.
There are two screws with lock nuts, I was hoping that they were eccentric as to raise or to lower the part of the table closest to central table but they are not eccentric and so I cannot use them to lower or raise the tables. I guess there is nothing I can do.

I believe this is how it usually is – the part near the main table is lower as to avoid trying to keep too many points in a single line. the only things you need flat is the main table, the infeed and outfeed are supposed to help you keep LONGER boards that need extra support in line with the main table – that is – they only need to have the edge farther from the main table inline with it – other wise you are running into a risk of trying to align 3 stamp tables in perfect alignment along their entire lengths – which is practically impossible.

again – the infeed, and outfeed are there to support LONGER boards until those boards are picked up by the 2 rollers, in which case they they are usually no longer needed much.

I have a 36” long “Sled” that I leave installed on my planer to avoid snipe. It it just a flat piece of 1”+ thick shelving that is left in the planer and is held in place with 1”x2”’s screwed to the bottom of it on each end of the in/out feed tables to hold it in place. Works for me.

If all adjustment possibilities fail, get a 12” wide piece of melamine, add a cleat to the underside of the infeed, and just use the melamine board as your infeed, main, and outfeed tables. You’ll loose 3/4” height and will skew any measurement references.

How much snipe do you have? I have the same planer and new knives reduce snipe. Supporting the board in and out reduces snipe; but there is always a little snipe, usuallly that sands away. Even the owners manual says theres some snipe. I built the long table for feeding and it didnt do anything but take up space. Also, the less you take off at a time, the less snipe you get. hope this helps

To avoid snipe, you can try to adjust the in and out tables so they are slightly higher at the outside ends. In other words, if you looked at the planer from the side and it was exaggerated, the tables would look like a V. This adjustment may take a little trial and error, and it would be very slight for each table, but this should help with the snipe.

Snipe occurs when only one of the drive rollers is in contact with the board. If you don’t support the board as it is going in or out, the weight of the board will force the ends up into the cutter. Holding the board will never be accurate enough to keep the board correctly positioned.

How to counter this [based on standard small planer construction] is difficult to say.

Most of the time, when faced with this condition, your lumber is milled while it is long and the snipe is cut off. This can be “wasteful”, but, is typical in a production environment (when the snipe of lesser equipment is unavoidable.)

I usually have extra anyway, so , this is not a problem. I don’t use my materials based on a board containing just enough to get everything out of it. There are too many defects to get around, whether it’s a live edge, knots, checking, etc. To me, it’s more efficient to cut off the snipe in 2 seconds, than to spend the minute or more sanding it out.

Otherwise, adjust your infeed and outfeed to match the fixed center table with any appropriate extra to help support the changing balance of the board.

Thank you all.
I believe that we should start a campaign for “PurpLev as president” as most of the time he comes up with the best answers.
I have little snipe nothing huge but I wanted no snipe.
I now believe that my tables are fine and properly adjusted.

Purp for Prez! Okay, it does have a nice ring to it. And it would fit on a bumper sticker.
