Planer Accurate Depth of Cut

<< < (3/3)

ZebraDriver:
Not all planers have wedge shaped slots. The smith machine that I was working on has two large plates clamped on the side of the block. Each held with 4 studs (probably 5/8 or 3/4 whitworth).  The plates are machined to provide a recess so that they will hold a 1/8" thick blade but there is no wedge - the blades are held only by the pressure exerted by the studs/nuts

Even some of the Wadkin machines don't have wedges or wedge shaped slots.  The securing screws are angled in the block and the seat for the end of the screws in the "wedge" is angled but the ""wedge" itself is a parallel piece, as is the slot. We've just refurbished 3 9BFT machines for one of our customers  (another four to go) and they are all the same as this.

I've just ordered a 12" travel remote indicating DRO for my Dominion combination machine that should aid determining thicknesser settings more accurately than previously.

Not arrived yet, but I'm hoping I can mount it at the side of the mechanical indicator picking up the current pointer with a custom 3D printed adaptor. the display can go anywhere as it's a magnetic mount  :thumbup:

Hi
Part of my job was servicing and setting up Tobacco Cutters that had 5 Knives mounted on a large drum that had automatic knife advance with a powered grindstone that advanced and dressed with a fixed diamond to keep the clearances correct.
Often wondered if this principal had been applied to a planer.

ZebraDriver:
Some woodworking machines have dressing stones that can be used to give the blades an edge between sharpens, but I've never seen one that could advance its own blades. Perhaps this is one of these issues where one industry could learn from another.
