Topic tags/keywords: knurling handles totes checkering hand tools

I can’t remember why I was researching how to do this by hand, but I recently discovered—and am enthralled with—Dem-Bart (or Dem-Bart style) checkering tools.

https://youtu.be/4lbK3us_JCY

Why is this cool? Well, because doing it by machine is impractical for a hobbyist. That is, that the hand tools make it easy to checker a curved surface, not only that, but, you can also choose the type of peeks you want (flat, rounded, etc.).

Oh, it just came to me, now I remember why I was looking into this …

I wanted to know if it was possible to add knurling to a wooden knob without a lathe and then I stumbled upon hand tool gun stock checkering which is like knurling.

Got me to thinking that, hey, this is pretty cool because I could essentially knurl anything. I could for example put knurling all the way around a pentalobe thumb wheel, including in the recesses (something that would be pretty hard to do on a lathe, even if you had a knurling wheel).

My brother used those kits building rifles. I wish I could have got some of his tools when he passed but his wife had an auction company sell all his stuff.

Pask Makes YouTube channel has a video about making a knurling jig for metal but it has a limited height so is really only suitable for a thumb screw.

This process sure takes a lot of patience. As with carving, too much detail for my liking and ability. Takes a real skill. It’s amazing to see the process from start finish. The sealer is magic. It takes it from a rough draft to a masterpiece in seconds. Cool stuff DevinT, thanks for posting.

It is extremely cool and extremely tedious. I’ve watched it done a few different ways in the past but they all basically boil down to the same method with slightly different tools. Once upon a time I thought it would be neat to checker some plane totes. After a little research, I changed my mind :-)

As far as knurling on a lathe, it has to be a round part. You couldn’t knurl in the recesses of a pentalobe knob. As with knurling though, you would need to determine your checkering pattern before making the knob to ensure you have proper diameters everywhere. So if you want to use a 20 ppi tool on the long axis, all of your diameters need to be evenly divisible by .050” for example.

I must confess this thought had crossed my mind. What research did you uncover that caused you to change your mind?

Right. I have neither the need nor desire to knurl the recesses of pentalobe knobs, but concocted that scenario specifically to illustrate where checkering could succeed and lathe fail.

Yeah, that Dem-Bart plastic triangle is actually key to their kit. The LPI (lines per inch) is integral to the angles of the master lines. It’s why the Dem-Bart system uses a 3:1 ratio and also why on gun stocks when the artist is checkering around, it is essentially just translating the position of the Dem-Bart plastic diamond about the gun stock.

Around 125.00 for a Dem Bart checkering kit on Craigslist.

- waho6o9

Yeah, I’m seeing about the same prices for the full kit on fleebay and glamazon.

I want to acquire one of these sets, but I’m tied up in other projects. Will need to wait until Christmas I suspect.

I mean,goes without saying that the super overly unnecessarily complicated kerfing plane would NOT be complete without knurled handles.

Just the time and effort involved to do it. Nothing leads to me think it can’t be done. Just that I don’t want to do it ;-)

As you probably know, checker is engineered to help grip. So it grips your hand without any adverse affect. It has a different feel. It’s not the smooth silkie feel of a well sanded rosewood tote, but rather something that is holding you.

In a firearm, it’s meant to help consistency. In a hand plane I think it’s more for decoration, but I like the feel.

Hand cut checkering has a completely different feel from pressed checkering. It’s a warmer feel. I always recut pressed checkering to get that feel.
