Default Wolf Cub Drill Restoration Question

Hello
I was just wondering if anyone could help me identify a small electrical part from my Wolf Cub Drill? I am pretty much a novice but I suppose we have to start somewhere. The bit was just detached from one of the brush wires.
Thanks

That's a suppression choke, designed to control the interference caused by sparking between the brushes and the commutator as it rotates. In times-past, this interference - if unsuppressed - could wipe out TV/radio reception over a wide area.

Yours looks like it's come to the end of its useful life - I'd suggest maybe something like this:

as a replacement?

Hi John, it should work witout it but may give radio and TV interference.
Spare brushes are still available, if you get over this way I may be able to find you something suitable.
These drills, if serviced occasionally will go on forever.

I also have its bigger brother, a real "gut buster" that has done a very serious amount of work over the yeas and is still going strong.

Many thanks for your replies. I have ordered some of these chokes.
As we speak I am putting it back together so when it's done I'll post a pic and results.
Got 2 B&D drills to look at after this, both absolutely filthy, quite enjoying this new hobby.
Thanks guys, keep you updated.

You might find you want to build a speed-controller next, which greatly increases the range of things these can do in metal (otherwise they go a bit, or a lot, too fast). Then the folks on here will really get their electronic teeth into you

If you like old drills then I suggest you have a good look through all the pages of this thread - you might be surprised, then add your drills, with pictures, to that thread:-

That brings back memories - my dad had one in his tool cupboard - didn't work and it weighed a ton! Hmm, or was I just small and weedy?

I have a big SDS drill now and walls simply tremble at its approach!

Personally I would not want to use a metal-clad power tool like that.
At the very least, fit an RCD plug .

Agree. Many of these old tools required an earth and were lethal when used outdoors or on damp surfaces. The earth wire could be cut, pulled from the plug or come into contact with the live wire due to cuts etc. It was the same problem with early electric lawn mowers. They are all double insulated these days or run from a 110v isolation transformers for safe use for outdoor applications such as building contractors.
Enjoy your old tools but only use them through an RCD.

Wow, I haven't seen a Wolf Cub drill like that for over 45 years. Well worth restoring, very cool drill. I remember trying one out after I graduated from a push/telescopic style hand drill and thought all my Christmases had come at once.

The modern world of plastic double insulated drill enthusiasts would probably frown on that lovely metal body. I think its great, just make sure its properly earthed.

If I'm worried I always run them via an isolation transformer.

Have you seen that other drill thread I linked to, Argus?
