Thats a great idea with the shift knob.

I never tried, but id bet the hematite is not too hard. You see different shapes sold for not too much money. That implies that it is easy to machine and polish.

Those diamond core drills you have will work. However, they are very slow. You need to use very light pressure with diamond core drills otherwise all the diamond chips come off straight away. When younare finished drilling, you would have to break the core out of the hole. The core in a 25mm diameter would probably be about 3/4" diameter. That could be really tough to break off. And, use the core drills with flowing water to manage heat and flush the slurry away.

I never tried using core drills in stages. My intuition tells me the first hole would go OK. However, with the subsequent holes, it may be really difficult to get the larger size bit started in the previously drilled smaller hole. Id be curious to learn how that works if you try it.

That carbide tipped Bosch bit you have looks like a glass and tile bit. I would try that first.

I thought about it and theres no logical reason to go up in stages with core bits - the smaller holes serve no purpose whatsoever lol

I hear you about the tile bit - I will buy one of those if the 12mm core fails. Starting and controlling the drilling shouldn't be a problem in the pillar drill with the work clamped ...hopefully :big grin:

I came up with idea because Ive become intrigued by the claimed metaphysical properties of crystals and stones. I looked up which stone to get and Hematite is meant to be very protective against negative vibes, help focus and strength. They are meant to work best when close to you or even better if you are holding them so a shift knob for a manual/stick thats in my hand most of the time when i need that protection, focus and whatnot. If its all bull, and its just a cool shift knob that fine too lol it matches the colour of the car pretty well

Nice car. Looks Australian. Never been... would love to go.

The body looks really straight and clean. What year is it?

Hematite is always a very interesting material. It is always interesting to hold. I really like the metallic look and the heavyness. Id bet you could sell nice hematite shiftter knobs.

Its 1986 Ford Capri but they started making Capris in 69 so a bit of a classic here in the UK. Mine is one of the very last. They are actually very popular in Australia - they were the only country that got a V8 from the dealers - we just got V6 and 4 bangers. A lot of people my age had an uncle or older brother who had one - often the black sheep of the family lol

I heard Hematite is magnetic too. I bet your right about it being soft. I don't know why but pure intuition told me it would grind no problem. As you say, people are obviously working it

I know theres a lot of love for old Ford stuff in Oz. My steering coupler bush came from Australia! - they are the only people who make an upgraded polyurethane one. I really like Australian Ford "Barra" straight six engine (Falcon engine) and came close to getting one shipped here for a project. The shipping cost was the deal breaker lol Cheers
