Dominion Planer Thicknesser help

[Vann]

...In the picture I'm pointing at a tiny hole (3mm there's 4 of them around the circumference of a thing I know it not the name?? ) is this how I raise/lower the infeed roller to enable a deeper thicknesses cut ? ...

I know nothing about Dominion machines, but on a Sagar planer/trhicknesser those springs have nuts/wingnut for adjustment (they're supposed to all have wingnuts but I guess two are missing in this photo).

However these are for adjustment of the pressure of the feed rollers and pressure bars - not for adjusting depth of cut.

Can you post a more general photo of your machine? Depth of cut is almost certainly controlled by a large handwheel ( but I think you may be meaning something different).

Cheers, Vann.

Thanks Vann, my bad……which isn’t an isolated incident much to my embarrassment

The gibs on woodworking machines tend to be parallel bars rather than the tapered variety found in metal working machines. They are used to take out the slop created by wear and keep the machine working accurately.

I’m finding it hard to visualise what your photos refer to. However, I think its the infeed roller. The infeed and outfeed rollers have springs underneath them that allow them to move up and down as stuff passes through the thicknesser. The roller height is set by different systems, I’m guessing that the collar you refer to is the height setting adjuster. I suspect that the grub screw needs to be slackened to allow it to be rotated. There will be a locking mechanism and I think this is it. If it has round holes in it, you need a spanner. I wouldn’t adjust these settings unless the stuff isn’t feeding correctly through the thicknesser.

Im not sure what you mean about setting the thicknesser depth of cut, this is done by adjusting the height of the table ie winding it up or down. The infeed roller adjustments have nothing to do with the thicknesser depth of cut, the adjustment is there to facilitate the rollers correctly gripping the stuff being fed through and to move it smoothly through the cutter without marking the wood too much / requiring too large a depth of cut to remove the serrated infeed roller marks.

Gibs.

Here's an example from one of my machines.

A table slides between the two "dovetails". One dovetail is the gib for adjusting play to take up wear etc.

Edit: or as Deema says above - sometimes the gibs aren't tapered - in which case I guess they have a retaining plate to stop them lifting away from the gib.

HTH.

Cheers, Vann.

My explanation about gibs isn’t very good, wood working machines tend to have shaped gibs (rectangular, dovetail etc) that are parallel or straight along their length. Metalworking machines tend to be tapered along their length and need adjusters at either end to hold them in position and not tighten up due to the moving part ‘dragging’ them and creating more ‘wedge’.

@Vann lovely machine.

Autocorrect is NOT your friend, or not Deema's friend anyway. I believe he was intending to type "gibs" - as in lengths of steel/iron with one side tapered. When located in the machine these will have two or more bolts engage the non-tapered edge. Used to adjust the amount of play in sliding "ways". Too little play and the movement will be locked tight. Too much play and things might lozenge and jam.

Cheers, Vann.

Thanks

Thanks for this Vann, “Autoincorrect” is indeed aweful.
Gibs makes much more sense, I know Deema is talking about now. I think I need to take his advice about changing the drive belts they certainly are hardened but not cracked so I’ll get them changed meantime “as a matter of course”
Great Cheers
