Had a fellow AP member ask if i had a spare Gottlieb Chime Unit only one i could find was this sad example and i couldnt bring myself to give it to him as i found it so i decided to do a rebuild thread with it.
Not much to these so should be short and sweet
Here is the unit as found (Most likely salvaged from the titanic)
-
STEP 1. Remove the chimes by undoing the nuts and lifting the Chimes straight up
STEP 2. Tip the unit upside down to get the Plungers out of the coils hopefully these fall out easily.
-
STEP 3. Remove the coil bracket and coils by removing the 4 screws hard to see in the photos from all thr rust but
they are there
-
STEP 4. Remove the coil brackets by undoing the two nuts and bolts per coil then slide the bracket down the coil
sleeve and off the unit.
STEP 5. Remove the coil by gently sliding it down and leaning the top outwards being careful of the solder lugs
-
STEP 6. Un screw the black plastic box from the back of the unit by removing the two screws (Its all to easy)
STEP 7. Clean up time depending on the condition of your chimes a wipe with a rag may clean them up well but for
this i went with the wire wheel on an angle grinder
-
STEP 8. Any parts that i could buff i did this includes the chime plates the strike plungers and any nuts and screws
etc. If you have acces to a tumbler they could also be tumbled ( I really should invest in one of them
would save my poor finger tips from the wire wheel and buff lol)
I forgot to add that you must remove the rubbers from the chime unit before you buff them to remove
them gently squash them through the hole in the chime
STEP 9. I use armorall to clean up any plastic and rubber bits works great on everything ive tried leaves em nice and
shinny.
-
STEP 10. Clean the coils and coil sleeves first i try to clean the coils with a dry cloth with the sleeves removed. I
then clean the sleeves dry but if that fails i use metho on a rag to clean the insides of the tubes i slice up a
rag and feed it through the tube a few times. The sleeves could be replaced if you felt the need but as
they shoot straight up and down there is little wear so as long as the plunger slides freely they are ok to be
re used
STEP 11. To re assemble the coils just reverse the above process slide the coil in on an angle and slide the solder lugs
through the slot then slide the top of the coil sleeve through the hole on top then re install the coil bracket
and nuts and bolts
STEP 12. I added a new piece of rubber to the bottom where the plungers fall after each chime as the old one was
brittle and crumbling (orange thing)
-
STEP 13. Re install the coils and bracket using the 4 large screws you removed
STEP 14. Re install the Plastic box using the 2 screws removed
-
STEP 15. Re install the plungers making sure the Nylon end is facing the chimes
STEP 16. Reinstall the small plastic washers onto each thread 2 per thread
STEP 17. Gently push the rubber grommets back into the chimes
STEP 18. Place the Chime back on the unit and reinstall the Nylon lock nuts but dont do these up tight i usually only
tighten them until there is a few mm of thread showing
-
STEP 16. Re install the rest of the Chimes and nuts
JOBS DONE Just a slight improvement lets just hope Nicks happy with the result

Great work.
I'm actually speechless you DONT have a tumbler....Go to your nearest gunsmith and buy one.
I got a Lyman 1200 pro. Does the job and has not missed a beat.
-
No i dont have a tumbler i do everything the hard way by hand lots and lots of !!@ but as my mates say i have to much free time. But i might have to go to the gun shop and ask might have to sell some more spares to buy one
-

Definately worth the $$. You'll never turn back.

Looks bloody great to me mate! Bugger, I'm gonna have to put more effort into the other metal bits now to match up to your effort!

You can always just get a can of brown spray paint and make it look rusty again LOL
-
Great work, Daniel - as always !
Getting rust off is such a prick of a job.
