Day 11 Tool Modification (Pits and Porosity)

Bits1

Ready for another quick lesson? Today I get to address one of my favorite-est (not a word) subjects in the world….. Tool Modification. I mentioned before that I seldom throw away tools, bits, burs, etc. I am always trying to find a way to modify them into new uses. For one reason, I can make tools for the exact job I am doing, and 2, it is a free way of expanding my tool arsenal. (you should see my garage…..)

Here is a quick way to make a tool that works wonders cleaning those hard to get into areas. If you have a small used up bur, snap/break off the end and grind of sand with a sanding disc with between 3 and 6 different angles or “facets”.

These edges when spun in a Foredom work as a powerful burnisher that will grind and smooth rough areas that ordinary tools and burs can’t reach.

Detailing

If you work with casted pieces, then you are no stranger to pits and porosity. This little tool also takes care of small pits and porosity, where trying to polish these away usually just reveals more pits and porosity. Use this little rotary burnisher to rough up and “smear” the metal over the bad areas, then when you sand and polish, unless the porosity is extreme, you should be able to remove or repair these areas.

I have a huge selection of burs, burnishers, grinders, texture-makers, and pit-beaters to select from that I have made over the years.

Tools Reused

Now, put on that creative cap and make some fun tools to experiment and play with.
