Grub Screw Placement. Terms and Conditions. This is the story of how my custom marking knives went from an idea into my head, to a tool that people can use and treasure. In the 4 months prior to leaving, I was working at Axminsterteaching both day marking knife holder 90 evening classes at Rycotewoodand was also running marking knife holder 90 own business with the YouTube channel. Also, The style of handle you prefer may vary for the task at hand.

Also, The style of handle you prefer may vary for the task at hand. For example, starting a screw hole with an awl is much easier with a properly designed handle.

We also offer the new joiners knife style handle and the round configuration scratch awl handle. The handles are offered in a variety of woods and can even be custom turned in your choice of custom woods. The handles come with your choice of a stainless or black ceramic coated ferrule.

This was a big problem. If the grub screw was to be over-tightened against the side of Marking Knife Holder Zip the blade, there is a high chance the blade could chip and fill the blade slot with metal fragments.

As you'll see later in this article, these are impossible to remove. I tried so hard to avoid this being a carbon copy of David Barrons knife , but on the Marking Knife Holder Yellow flip side there was so little I wanted to change about his original design because I loved it so much.

In the end I decided to remove the bead at the end of the handle, simplify the shape, I also removed the shoulder that leads the handle into a ferrule, and I was to offer it in a variety of materials. With the addition of a visible grub screw, the design is now noticeably different to Davids original. One thing I couldn't distance myself from was the thumb-hold.

I thought it was genius. In addition, due to the fact my blade was removable, it meant that the blade could simply be flipped the other way around and it would be suitable for both right and left handers! The lathe had sat idle in my workshop for 4 months while I gathered materials to test the first batch. And I decided to film my first ever attempt at using the metal lathe for Episode 12 of Turning Tuesday. At this point, the knives were complete secret.

Barely anyone knew what I was up to! This is where the real challenges arose. I'm pretty sure I exhausted all potential cock-ups possible before finally coming out with a design and a process that works well.

Below are some of my favourite screw ups. There was a split in the rosewood that I didn't see. Suffice to say it didn't like the skew chisel touching it. I forgot to cut the blade slot before attaching the ferrule. Then ended up mashing it anyway I decided to highly polish the ferrule as an experiment, then proceeded to overtighten it in the chuck jaws The slitting saws I use are extremely flexible.

One second I was chamfering the copper, the next second my pants were brown. The shank was too tight in the handle, so I decided to machine it down slightly.

Ended up mashing the slot shut. When the araldyte joint failed, causing the ferrule to rotate around the blade holder. You could get a grub screw in that, right? When I forgot to set the depth stop on the drill and blew through the opposite side of the ferrule.

One of the many occurrences where the tap snapped while cutting the thread. This is one of the most annoying! Aradyte rapid didn't work for the wood to metal joint either. These often launched off the lathe. When the slitting saw broke and I decided to mount it on the lathe afterwards as an experiment. It didn't like it. When you're fitting the blade for the final time and it snaps in the slot. The only slitting saws I could find were available from China.

When I got carried away while sanding the handle and ended up shaping the brass ferrule too! A huge problem I faced was breakout within the slot. After adhering the ferrule to the blade holder, every time I drilled and tapped the hole there would be small amounts of metal that would prevent the blade from being fully inserted.

I considered assembling the ferrule and blade holder dry while drilling and tapping the hole, taking it apart, cleaning out the slot, then re-assembling it. But this would almost certainly make aligning the threads difficult. Not to mention the potential of threadlocker leaking into the pre-drilled grub screw hole! I found that inserting a piece of 0. I usually reserve these ones for myself, friends, and display items if I were to ever set up a stall at an event.

After completing the first batch of knives, I have since subcontracted the metal components of the knives out to a small local company. This stops me from having to spend hours slaving over a lathe and milling machine doing repetitive tasks and instead focus on video creation.

However, I still glue, drill, tap, countersink, and chamfer the ferrule myself. As well as turn, finish, and package etc. It's been a real rollercoaster trying to get these things going but the initial feedback has been incredible. I'm seeing lots of happy recipients of their knives all round the globe and I could not be more humbled to see people enjoying them.
