Hi racers,

I can't remember where I got it from.

I figured out that the one with the slots is usefull to deburr the brush hoods. But is this the reason the slots are cut into it?

[Cheater]

Never seen one like that... but your supposition is probably correct.

[MSwiss]

That's why I use to cut (and periodically, recut) slots / notches, in mine.

If they were precisely spaced on each side of the arm shaft hole, they would also probably be useful to center the hoods, if you were mounting non-standard hardware on an endbell.

[Koford fan]

Maybe these are references? To check if can actually centered with enbell/hardware by watching the slots from both sides, it should be possible to check by visual estimate or simply as you said.

Not long ago, I saw it in a web shop. You still can buy it (just can't find the shop right now).

In English, you would call this a notch instead of slot? So what's the difference between a notch and a slot?

Notch vs Slot - What's the difference?

Doesn't really matter.

It was very apparent what you were referring to.

[Benno - SAC]

Thank you, Mike.

In German the difference is almost the same.

Notch = Kerbe
Slot = Schlitz

So what's the difference between a notch and a slot?

 
If in woodworking, a slot would be a wider groove than a notch. A notch could also be a deep narrrow mountain pass. Sometimes we got different words for almost the same thing.

Benno, you have good English, we know what you meant.

[Jay Guard]

Although what everyone above has said is generally true, a slot is considered to have two sides, a notch can have only one side.  For example if you cut a 90 degree relief along a piece with an outside corner it could be considered a notch but not a slot.

Slot = Schlitz

 

Schlitz = Cheap American beer.

[Bill from NH]

The notch at the end of an arrow for the bowstring has two sides. When you incise a notch into a surface with a knife, the cut has two sides, too.

Thanks guys, for this linguistic excursion .

I always try to improve my English. And I've learned already much on Slotblog by just reading.
 
Back to topic:

the notches are precisely spaced, but with wide spaces. Must be meant for 26D and 36D motors.
 
(Have to memorize: never ever drink a beer named "Schlitz." )

[Bill from NH]

26D motors use a different size motor brush than a 36D. The 36D size brush is what has become the standard size for contemporary motors that use replaceable motor brushes.  

Are the notches only on one face of your tool? If so, I would question if they're placed there for deburring. Neither the tool nor the brush hoods are square, so you wouldn't be able to rotate the tool to debur each of the hood surfaces.

For years, I used fine-cut miniature square files to debur brush hoods.

[Benno - SAC]

The notches are on all four sides, all precisely spaced referring to the two holes for the armature. But slightly out of a 90° angle.
 
I wasn't aware, the 26D have different sizes, too. I thought 36D/26D have the big brushes; 16D the small ones.

[Cheater]

If the notches are on all four sides, I'd say that pretty much proves it was meant to be a poor man's Magnehone hood tool. As does the fact that the notches are not exactly 90 degrees to the tool's axis.

[MSwiss]

With notches on all four sides, it wouldn't be ideal to deburr an aluminum endbell, with its coating to prevent shorting.

If you use it with one, even as just an alignment bar, I wouldn't ever "freshen up" the notches on all four sides.

Two adjoining sides is all you need.

[brnursebmt]

Wow.

[Benno - SAC]

?

[The Number of]

I think Bobby was just amazed at how far this thread has gone round and round.

And in a side note if you ever had a Schlitz beer you would never forget.

[old & gray]

Schlitz was a remarkably forgettable beer drink.

Chippewa Pride, now there was a beer to leave an impression.

[brnursebmt]

Exactly, Bill.

[MSwiss]

Apparently that feature Greg installed on Slotblog that makes everyone read all the posts is still working. LOL.

[Benno - SAC]

It is because here you get five threads for the price of one:

 

1. What is my tool for?

2. English course

3. notches vs. slots

4. Tech tip DIY poor man's Magnehone

5. Beer brands not to drink!

 

 

Cheers!

[Dave Crevie]

Those are buenos notches.

Anyway, I always used those lines to check that the brush hoods are equi-distant from the comm.

[Cheater]

Dave,

I'd suggest not quitting your day job to go into stand-up, OK?
