We just received our first fully finished sample of our new Crucible Planing Stops. The cast ductile iron stops are all poured and are about halfway through the grinding process. So it won’t be long now.
The stops will cost less than $50. And they are incredibly simple to install:
- Drill a 5/8” hole in the wooden block for your planing stop
- Pound the iron stop in
- Uh, done.
Whenever we post photos of this planing stop or our holdfast, people remind us that cast iron is fragile. It’s a stupid material to use to make a holdfast or planing stop. You can’t hit it with a hammer – it will shatter. Heck, it will shatter when you drop it on the floor.
Even when we tell people it is ductile iron, they respond: Actually, you can’t make holdfasts from ducks, ducts or tile, either. Do the research!
Today, I beat our planing stop samples with a lump hammer more than 100 times each to see what would happen. As always, the answer is: nothing.
