The Growler

This 1920s growler can detect short circuits in the armatures of electric motors.

If you want to know how this works, I give a more detailed explanation in the full growler restoration video.

I knew what that was before I even read the title. We used one in college (2012) in aviation maintenance. Ours looked a little different. They still use it, with a hacksaw blade and every thing.

Toolz, a man can never have too many tools!

[Yoshikaable]

Cool to see a vintage tool being used to restore other vintage tools! Thanks for the demo

Back when they used to be able to rebuild electric motors. Thank you for sharing

I still have my late dad's growler that I use almost on a daily basis at my workshop

Yep, I see how this works and it would absolutely tell you which coil is burned up. It's simply reversing/inducing a magnetic field into the rotor and the ring on the commutator is just completing the circuit. Whoever built it... Cheers to you.

Brings back memories of my summer job when in college. i used one of those to test armatures. Most of the time the problem could be cleared, but some had to go back for rebuilding again. The problem was usually a copper shaving from when the commutator was turned, or a sloppy setting of a lead.

My mother was a cosmetologist. She still cuts the family's hair (even extended family). That bogged down motor sound just reminds me of her using her old trimmers on hair and hitting a thick patch.

I love learning about older technology like this.

In 1975 they taught us to use these in auto shop class,
it's a shame I hear they haven't been offering classes like this anymore.

I still believe that vintage tools will lasts forever and still do their job well

33 years old my highschool teach had one of these and taught me how to use it man bringin me back

My dad was an unlicensed electrician, who could run rings around licensed guys back in the day. He worked in the shop. head of maintenance department 40 years. Did everything, electrical, machine, tool, repair, carpentry, hydraulics, you name it. And with excellence. He always used to talk about putting an armature on a growler. As a kid, I never understood what he was talking about, although I did grasp it was something used to test bad motors. It’s so hilarious now to realize the friggin thing is exactly what it was called! Very cool. Well you just closed the chapter on a lifelong internal question I never had an answer to! 😆

I use our growler to demag large rotors and armatures before milling. Makes swarf clear much easier.

I have one of those at work. We work on commercial floor equipment, which occasionally involves rebuilding or servicing an electric motor beyond just a brush replacement. We have an armature lathe with an undercut wheel. The growler is detached but part of the set. I've only had to actually use that lathe maybe 4-5 times in the 8yrs ive worked there, but its handy when you have an armature that needs turned bc its not round anymore.

[davidgardner]

Dude. Never seen one of those in my life. I love it man. Some of the old tools are built so well and made to last forever. Hence the fact that you have one that's that old! Sick man! Keep it up!

[SOFTAILME]

I remember using one of those every day. Used to rebuild alternator and starters

[staffykclips]

I got taught at school that a “growler” was something totally different

[epinephrine]

What awesome equipment. Love the reliability of all the old school tooling.👍
