Default Table thickness planer reverse snipe

Hi everybody.
This is my first post/question. I have read a lot but never posted anything, maybe I am too much of a very part time "beginner". I have an 18 year old Toolmate 12 inch thickness planer. I have never had one hick-up with it. It has a little snipe but I always just sanded it away. I have made height adjustable aluminium extensions of 1,4 meters (55 inches) each for the in and out feed sides.
Recently I started reading about snipe and I realize that my planer has reversed snipe. The ends are a little thicker than the middle section.
Any suggestions how I can fix this or must I just keep on sanding it away.
I have worked with soft wood but am busy with white oak now.

Welcome to the forum Admar!

Never heard of reverse snipe, sorry. Someone else will be along shortly to help you Admar.

My guess would be that when you clear the infeed roller the head raises due to slop in the raise lower head position or misaligned outfeed table

Welcome Admar...

Sounds like your outfeed might be raised as to create an up angle relative to the feed rollers. Maybe?

Hi Admar - snipe refers specifically to the ends of a plank, and one of the causes, (presuming your in and outfeed supports are perfectly aligned with the planer bed), is the slight difference in downward pressure on the wood as it goes from one roller pressure to 2 rollers, or vice versa on the exit.
I don't know what could be causing your problem - it sounds like it is not a definite step, but a gradual difference from middle to either end.
Could it be that your in and out feed supports are too high, and are tending to apply upward lift on the planer?

Good Morning

Thank you for the reaction on my problem. I will check the alignment of the infeed and the outfeed and come back to you.

Hi All.
Regarding my reverse snipe. It is only on the ends of the material, about 60 mm or so and the ends are thicker than the centre. I have checked my in and out feeds. They were very short (150 mm) and not supporting the wood at all. I took them off and I made new ones from aluminium which are about 1400 mm long. Still busy but will align them properly and see what happens.
