Hembsy where did you get the holder for the dti , or did you make it ? if so how ? I've noticed on thicknessed stock that one edge is thinner than the other , i would like to determine if the rollers are level (is there any adjustment on these to set them perfectly level) ... and also to check the thicknesser table as you describe
Hi,
The tool & indicator are from
http://www.toolpost.co.uk/pages/Woodwor ... uring.html currently £71.39 very useful for a number of tasks.
Assuming your timber has a good flat side to place on the thicknesses table, if the thickness is then not parallel across its width is unlikely to be a problem with the feed rollers or cutter block bearings but not impossible.
Check the infeed & rubber outfeed roller move freely up and down on their spring assemblies. The spring tension is adjustable, but without a spring gauge I slacken the bolt at each end of a roller then retighten using the same number of turns at each end until the roller comes under firm tension. Not very scientific but seems to work
Remove the guards and visually check each end of the cutter block assembly for movement while attempting to move the block up and down (WITHOUT THE BLADES FITTED #-o )
Check the cutter block is parallel to the planer table with a DTI , there should be almost no variation at each end or in the middle. Should there be a large variation it would mean you may have a tricky problem on your hands, not insurmountable but!! The table has no user friendly adjustment, it is raised and lowered by a continuous chain on sprockets fitted to the bottom of each thread on the table corners, set at the factory. Not a good idea to consider this unless there is a big variation.
Ignoring for a moment the blades & planer infeed table, the basic principle is that the axis of the cutter block should be parallel with the thicknesses table and the planer outfeed table.
When these 3 axis are correct and the infeed table is then set correctly to the outfeed if the blades are set correctly to either the cutter block or planer outfeed table the planing & thicknessing all should be fine
.
The setting of the blades is of paramount importance in achieving a good planed surface & thicknessing but need the machine tables etc to be correct.
Hope this makes sense
