Oh I know the dial indicator, was meaning the red anodized block the arm is sitting in Is that particular to the straightness checking job?

 

Just checked Johns Arm winding thread here in this section, it is an RGeo V block...

[Pablo]

It came that way. Don't remember where I got it.

[Pablo]

dc-65x special BIT tool in place, ready to drill 5 mm hole in can for BB.

This is the poor man's method of motor building. No drill press or special tools here at The Wolcott Ranch. Just a hammer and a screwdriver   Some day I will buy some special tools, but now is not the time. I'm having fun in the meantime

5MM drill bit is hungry and ready to carve a perfect hole in the Mabuchi brass bushing thingie.

[SlotStox#53]

Hammer & screwdriver are the only way to build Build on Pablo!!!

[Pablo]

Here we go........

[Pablo]

The brass bushing came loose during the drilling process.

Oh well. No problemo. I'll soak the can in paint stripper overnight, and solder the bushing assembly back to the can, before finishing the 5MM hole. Patience and perseverance will pay off.

[SlotStox#53]

Gives you a chance to start on the Wolcott armature

[Pablo]

Mabuchi bushing all shined up ready to go

[Bill from NH]

I didn't think those brass bushings ever came out of a can. I know their gimble bushings aren't too secure in there, but I've  never had a bushing pop out like that. You learn something new every day.

[SlotStox#53]

Bill I think it's just a case of those cans just never had a run in with Pablo wielding a hand drill and a modified 16D BIT Tool before

This is out of sequence, but, YES, I did check the arm shaft for straightness before fooling with it.

This one is very very straight.

Hi Pablo,

 

If you or anyone else know where to find that arm checking gizmo please let me know

 

I'm glad the BIT is working for you

[Pablo]

I should have known......I looked at the base of the tool, Rick T, and found the answer:

So it's a RGEO tool with a dial indicator added to it.

 

I just bought a new tool at Lowes today. Did you know they give active and retired military discounts ?

Horno Tostador   Wheeeeeeeeeeeee !!!

What brand of arm is that beside the Hawk (Champion) can in post 12? I've got one but no idea what it came from.

 

Champion Thumper.

¡Muchas gracias Pablo!

 

Muy bueno!  Me gusta la pizza.

Look at post #16, Bob.

PdL says it is a "Igarashi". Who is confused, and who is right ?

I know I am confused, that is a given.   Whatever it is, I like the comm; the tabs are bendable, make a nice nest for the wires, and stay tight to the comm.

As long as we are on the subject, why is Don H. calling my blue Mabuchi can a "Hawk" ?

 

Can has been stripped of the old blue paint. Hope the primer and new paint will hide the nicks

Time to re-install the bushing. Where did I put that doggone mini-torch ?

[Bill from NH]

Is that Hamilton Beach oven for you, the doggies, or to toast the arm?  We have an Oster. When home alone, I have heated up a few Chinese arms when we used to retime them,

 

Fill the can nicks with 60/40 solder & sand the spots smooth.

[Pablo]

I was looking at an old Ron Hershman post where he said the fumes released while baking an arm are extremely bad for your health. Even after the arm was done. He said do not use the same oven for cooking, ever, and bake the arm outdoors.

[SlotStox#53]

Will have to invest  in one of those Horno Tostador thingies soon myself Can definitely imagine baked epoxy fumes being not so kind to ones health !

 

Wonder if the whole gizmo (shaft straightness checking tool)  is from RGeo? not just the V block that someone added the dial guage to? Oh Mr. RGeo !

[Pablo]

Put on your glasses, and re-read post 37

[SlotStox#53]

  indeed   Started winding yet Sir?

[Pablo]

Bushing was prepped by winding one wrap of .032 silver solder around it, and slathering it in acid.

Then hit with the minitorch   I aligned the Koford BB and soldered it home using the same method.

[Bill from NH]

Paul, mine isn't anodized, didn't come with a dial indicator, but has the mounting post for one.

[Pablo]

Thanks a million for the tip on filing in the nicks with solder, Bill.

I filled in the notches too !

I think it's going to work fine.

Hawk got out and Champion of Chamblee bought up the inventory They tach tested and took the cream of the crop ("1 in 10") and labeled them 501. The weak ones were rewound, re-comm'd and balanced. Thus the 507 was born. 

 

The comm tabs on the Thumper arm are very 'user friendly' ..... but thin and fragile. Roger at Mid Am had some arms that were probably purchased bulk or repackaged as Motors Etc..

 

I don't know who the OEM was for the Champion Thumper.  They definitely were made post 5001 and I think this was the Champion standard/industry in "Stock 16D" production arms of the 70's.

[Pablo]

"Hawk got out"

Sorry, Bob, but that makes zero sense whatsoever.

This is the second time I have asked for an explanation of the term "Hawk"

Please explain it in layman's terms.
