Thread: Eliminating snipe on thicknesser

Maybe the blades are not adjusted correctly as they must be lower than the feed roller or the feed roller needs adjusting. The exit roller must be correct to the blade at present that is why the snipe starts at the beginning then the exit roller holds the timber down to the correct height explaining why the snipe stops. If the snipe was at the end then the exit roller is too low. Check your manual to adjust the machine correctly. Once you have done that and snipe is still present then it might need a trip to the relevant service department.

Thanks Col. I checked the manual, but could not find any reference to adjusting the rollers. See attached.

I will have a go at re-aligning the blades

Or put a sacrafice piece thru in front and behind your good timber. End to end so the snipe is on the rubbish timber and not on you good stuff.
At least until you sort it out.

On my little Delta 12" the snipe occurred when heavy boards would cause the outfeed tables to move (depress). As the board tipped fractionally, notably at the ends, so it would cut deeper = snipe.

The solution was to support the ends of the tables, and ensure that they did not move out of flat under even the heaviest load.

One strategy was to use separate in- and outfeed supports. But the biggest gain came from building supports under the tables ..





These were adjusted with hex bolts ..

Thanks Derek, I'll give that a go too! As well as checking the blade alignment
Appreciate you posting the pics - makes it easy to understand. Yes, the trays are flimsy cantilevers, and you have certainly fixed that.

Thinking about it a bit more, I have rollers stands either side, though, so they should work just the same as your solution?

The other problem I have is my newly completed cabinet : the indeed and outfeed trays project past the edges of the cabinet . Easily fixed by unbolting the base of the thicknesser and sliding in a long board like you have used

I found adjusting the in/outfeed tables so they are just a whisker higher than the rollers eliminates snipe almost completely.

Woolffie, what that is doing is just preventing the tables tip as weight is placed on them. Make the tables rigid.
