A friend of mine needed a bushing assembly for his street bike to be reduced in width by about 0.230″. Having a 1930’s South Bend Lathe in my shop, I naturally said “come on over”.
My respect for machinists just went up a few notches (it was already high). I’m also glad I got a 4 jaw chuck for the lathe instead of a 3 jaw.
4-jaw chucks allow you to hold irregular work and precisely center it. The process for doing so can be tedious, but it’s a good feeling when your indicator reads in at less than 0.001″ variance from side to side.
This little project was fun for a few reasons. The assembly comes apart into several pieces. The little ring has multiple inner diameters used for different things, so it needed to be machined carefully on both sides. Holding small and irregular parts is a challenge. But seeing it all come together was great.
Recently I needed to align my CNC router spindle to the table. Part of doing this involved tapping on metal parts here and there. Not wanting to damage them, I needed a “soft” hammer to use, so I quickly made a brass hammer.
A closeup of Brazilian Cherry (Jatoba) and Maple.
Here are a couple of pictures of large pinecones made out of soft maple.
They were carved on the CAMaster CNC Router and finished by hand.
Here are a couple of pictures of a recent Sinking Valley Woodworks project: a Brazilian Cherry Butcher Block Cutting Board.
It’s solid end-grain, glued up with Titebond Ultimate, and sanded down to 2000 grit. It simply has mineral oil – the gloss is from the wood itself.
What do you think?
Here is the finished product.
Notice how glossy the top is? That’s what happens when you take Brazilian Cherry end grain to 2000 sanding.
The swirls in the grain pattern were intentional. As the pieces were glued up, the grain was alternated creating a very neat final pattern.
Here is a closeup of the grain.
This is prior to any mineral oil being applied. Notice the reflection of the light that is 9′ above the surface.
I-Beam clamps. They are great.
We have some old hand forged nails. The nails were made by a blacksmith.
We polished them with a Dremel tool using a wire brush. Did you know that a Dremel tool can spin 500 times per second? Wow. We wore safety glasses to protect our eyes.
Here is a polished nail.
Here are some facts on old nails.
- Old nails were once so valuable that when a building burnt or fell down people went through with magnets to find the nails and save them.
- Nails provide one of the best clues to help determine the age of historic buildings, especially those constructed during the nineteenth century.
- Between the 1790s and the early 1800s, various machines were invented in the United States for making nails from bars of iron.
Here is the a chart for nails. (Copyright Thomas Visser)

That is all for now!
The CAMaster Cobra 508 has arrived! And I have a helper.
