Using gunstock checkering tools for making matched grooves

What does it look like? I guess anything that will groove wood can work, but why use non-historical matching grooves? (except for making european crossbow-prods)

but why use non-historical matching grooves?

I am an egineer not a historian :twisted: :twisted: :twisted:

I would assume that matching grooves would produce a joint that is less likely to delaminate and perhaps also easier to glue.

Tool building is fun too, but will distract from original goal, so I would prefer to buy tools, when reasonable.

I do not know much about checkering tools, I got a tip, when i was building my own grooving tools in a woodworking class. I do not remember seeing this here, so it must be a new idea, or a bad one.

and google checkering tools or gunstock checkering.

The biggest pattern i found quickly is 16 lines per inch which is 1.6mm.

I was thinking 2.5-4mm for matched grooves.

10 TPI = 2.5 mm
16 TPI = 1.6 mm
20 TPI = 1.3 mm

I think 12-16 teeth per inch is normal for turkish bows.

These tools look quite interesting. You are definitely on to something here :)

I found a few mentions about some pre WW I firearms having 10 TPI checkering, but I found no tools below 16 teeth per inch.


Images to clarify what we are talking about.
