A shop trick for making do and/or saving money.

I’ve been tapping threads most of my life and only today, at the age of 39, did I buy my first bottoming tap.  Depending on what you want to do, hand taps for a given thread come in a few shapes.  Most weekend warriors are familiar with taper taps, but when you need to get threads to the bottom of a blind hole they won’t do:

See?

Now today may be the first time I’ve actually bought a bottoming tap but I do own a few.  Here’s the tip:  Whenever I’ve needed one I would take the taper tap for the thread I want, grind the tip off, finish the job, and then replace the taper tap at my leisure; possibly days later.  It’s cheaper than buying a bunch of bottoming taps that you may never use.

FYI:  I bought the bottoming tap today because:

1)  I knew I’d be needing it to finish the job on my bench.

2)  It was right where I was shopping for something else I needed.

3)  It was inexpensive!

Finally:  If you don’t know how to grind tools, please don’t use this advice as inspiration to go out to the shed and wreck your taps.

A telling stink!

I was savouring the smell of my late morning coffee and thought about odours.

On a recent shopping trip in Coquitlam I went into a KMS Tools and a Princess Auto store within an hour of each other.  They both sell some similar products from offshore suppliers but they smell rather different and that shows the differences in their focus:

While the air in Princess Auto smells mainly of rubber, plastics and has “mercaptan-ish” feel to the whole place, KMS Tools mainly smells like oil and Cosmoline to me.
