Here's another way to restuff those twist lock can caps.

Can also be applied to multi-caps cans. I've used that method
many years ago and never transfer the how-to page from my
first website version over 6 years ago...

The big difference lies in the way to reseal the top. Since
even new electros have a definite life, if one needs to re-open
the can, this way much simplifies the task.

First step, get yourself a glass of orange juice...

When done, cut out the plastic spout and cap:

Cut the electro using a sharp Olfa Blade. Rock the cap under
the blade while giving slight pressure. Once the blade cuts
through a small portion, roll the cap until completely done. It
will make a perfect hsarp cut everytime if you go slow and do
not put too much pressure as to dent the aluminum can.

Glue the spout to the top of the electro:

The cap will be glued inside the can cap. In the picture I cut the
cap to seee through but it is not needed. Use a hot glue gun to
attach both spout and plastic cap to can capacitor.

There you go...Seamless and restuffable in 10 seconds...

Holy Mackerel...that is cool....thanks for the info...I only wish I had thought of that first.

Syl, I don't understand why you remove the top of the can. The new caps have to be wired through the bottom and I remove the bottom only.
I replce the base discs with a small (3/6 high) piece of PVC pipe that's slit and expanded to fit tube, glue those all together slip it back in with caps connected and use small (#2) screws through can and into that pipe ring. You can remove can any time by removing screws and pulling off. PL

Hi,
I like to see many ways of doing something, and this is one that I might try next.
I have done the restuff many ways, from the bottom and the top, but this is clearly a good way to have access in case you need to service this cap.
There is no ungluing etc. and I had never thought about adding a screw on access top. Thanks Syl.

Syl, as always, thanks for your excellent help on all the repairs! You are a true pro, and, very kind to share your high intelligence!
Now, if we could find a source for the crystals....... Icon_confused

Thanks, again, for your help.....

Came up with that idea after a freshly rebuilt cap went bad. I hit several bad -new- caps in a batch from a local supplier. I took the habit of testing every parts years ago but sometimes too much confidence can be a bad thing.

Was this supplier Addison by any chance? They often sell new parts that just happen to be 20 or 30 years old. I bought some .01mf 600v condensers from them a few years ago and found that some started to break down at 250vdc on the Condenser checker. Most of the stuff I've bought from them was alright, but I don't remember whether they had high voltage electrolytics at the time I ordered. Not a bad way to renovate an old condenser can, thankfully in most cases I can find enough space underneath but I may try something in the TV rebuild coming up.
Happy Christmas

I guess I will have to start saving the lids/spouts since trying to rebuild the lytics by cutting the bottom off makes the rebuild obvious even if you use the chrome tape. There are 3 to 4 well documented methods but this one makes the rebuild a bit easier, thanks Syl

Yep, Addison all right.

The caps were not that old, maybe 5 yo or so but from an odd brand.
Most caps I buy there aren't that old and are usually good brands;
Rubycon, Nichicon, Philips and Gloria on the low end.

Actually, it wasn't Addison but AddTronic in Laval,
most probably a "branch" of Addison as they sell the same spray lubricants and all
branded Addison.

OH GREAT!!! Now all the druggies will want old radios to hide their stash..... Icon_mad

.... Only kidding - great idea!!!

gws · 03-02-2011, 08:30 PM

Just for your info. I buy most of my electronic stuff from Digi Key out of Thief River Falls, MN. Note I am not connected with them in any way.

Their a big supplier and have most everything you need. Also they don't have a minimum order charge and take credit cards. Ususlly ship the same day!

Cheers

I just tried your procedure and it works great Icon_thumbup

Thank you for posting it! I experimented a little and ended up using the cap and neck off of a small water bottle. they are the same size and I think the water bottle plastic is a little more rigid. Not that it makes any difference, both seem to work well!

Thanks Syl. It gave me the same chuckle as when you posted it years ago. It's just such an elegant solution.

Chicago Jimmy · 07-19-2011, 02:53 PM

This is my first cap can. I used the bottom and siliconed it into the cardboard sleeve. I carefully cut the lip that held the bottom disc on the can.Cleaned out the can on my drill press with a spade bit. Then added the 3 caps.
