Technical terms?

[needlotsofhelp]

hi everyone. i struggle with quite a few things and have absolutely no idea what flatting, deeping or bevelling means pleeeease help

Bevelling - the process of putting a angled flat edge between the side and face of the material, either by sawing, other machining (such as routing) or planing. Removes the arriss (sharp edge).

Deeping - the process of deep ripping material on a rip saw where two rip cuts are made, one from each edge. Allows a smaller capacity saw, e.g. a saw with a 4in depth of cut, to rip almost double the nominal depth of cut by making two four inch cuts from either side. Widely regarded as a dangerous practice because the crown guard must be removed (sometimes also the riving knife) and the process is highly prone to kickback. Use of the bandsaw for deep ripping is preferable to "deeping" on a rip saw even if a jig is made specifically for the purpose of deeping on the circular saw. See also HSE notes.

Flatting - could you state the context in which this is used as there is more than one possible meaning

 

[needlotsofhelp]

a circular saw can be used to re-saw timber, "such operations involve ripping timbers with the grain and are called flatting" it makes no sense to me so i'm trying to find out as much as possible about it. much thanks to your quick reply

I've not seen it used in that context and think you must be looking at a very old text.

The process of rip cutting is just that - ripping. The only conceivable process which makes sense described in that way would be the rip sawing of waney edges away from waney edge stock to create a straight or flat side, although that process was being referred to as "straight-edging" or "straight-lining" well before WWII.

Now as we know you're not doing this for a course, why did you want to know?
