1951 Pontiac Chieftain - Locks

Recommended Posts

Ok. Chieftain time!

20200629_112235.thumb.jpg.2640c1f6c4d7cabc43e55c4b09b3c7b7.jpg

Recall a while back, I dropped the keys in the parking lot at the store and someone pinched them rather than turn them in? 

Decided today to remedy that. So, I pulled the lock barrel out of the trunk lid.

Using nothing other than what is in that picture (.0015 feeler gauge, bent paper clip, pliers) I picked the lock and disassembled it. Books say that the side bar style of lock cannot be picked with regular tools. It can but it's not that easy. Anyhow.

With it all pulled apart I was able to get the "code" of the lock. There are only 4 height steps on these barrels so I am going to go to the hardware store later and see if they have the correct blanks, buy a couple and see if I can file my own keys to make the lock work.

Lock picking does give a certain sense of achievement and is moderately therapeutic. Certainly a fun puzzle.

First lock I've ever tried to pick.

Bought a blank. Marked it up to depth.

Filed it down.

Cleaned and lubricated the lock, reassembled it. Now I have a key for the trunk and the glove box again. I'll get a spare cut from it.

 

Next up, I'll remove the door handles and find out what key blank they take- looks to be a much later shape, 80's truck. I'll try cut a key for that then I'll be able to operate the locks. That'll be nice.

Total outlay for today $2.

This is one department I'd be tempted to throttle the maker of the camper bit of my van.  Why on earth did they feel the need to have a different key for every single locker/door?!?  Means there are seven keys on the keyring for that vehicle alone.  Side door, luggage locker, toilet access hatch, gas locker, water fill cap, then the doors/ignition and fuel cap for the actual van.  Why the side door, gas locker and luggage locker couldn't share the same key I've no idea.

Decoded that and cut a key. Not enough pieces in common with the ignition sadly but I have a key that works both door handle locks now, at least.

This one needs adjustment and lubrication, but it does try to move the mechanism. The driver's side is missing the rod for the pin... That needs to be addressed.

I reassembled the door lock (funny, discovered after the fact you can pull the handle off without taking the door card off), I need a new rubber O-ring for inside the handle. The old one fell apart. It serves two purposes. First, it stops the button going CLACK if it's released hard, second it positions the lock mechanism to engage properly with the barrel. Right now I have to push the button in slightly to get the door to lock and unlock, but the driver's side works properly. I will pull the door card off the passenger side, remove the button rod and copy it for the driver's side.

Decided to wing it, so I went liberated a plastic coat hanger with a metal hanging hook because it looked about the right diameter and length.

 

20200701_205102.thumb.jpg.efad6d43523fd93a6ed9b6d3f732beb8.jpg

Heated it and bent it to shape.

 

20200701_205157.thumb.jpg.f1297b30ff6e2bb0f0ce1e92a2da78f6.jpg

Added a piece of insulation off a wire to bring the diameter up and give the pin something to grab on to.

I've been informed that the most common cause of the windows breaking in these cars is either deteriorated, missing or otherwise faulty window channels.

The glass gets hung up going up, the operator gives a jolly good heave on the regulator handle and CRAK, the pressure point created by the lift arm in the center of the glass support fractures the glass.

Makes sense, both windows that are broken the cracks originate from the lower edge in the middle.

Had a little time today so started on the wiring again. 

Got the alternator primary run through and terminated. Ran the primary from the fuse block up to the group terminal on the light switch- marked the outside of the wire where to cut by scoring it with my thumb nail. Got up out of the car, went get my big wire cutters, crimped the end on then found it about 4" too short. I cut the wrong mark! Argh.

So, I need to go get a few more feet of wire and a couple more connectors. Not the end of the world, for sure.

I don't remember those lock buttons on any British-market cars older than about '68. Weren't they a new thing on the first Escort? 

Were they a GM innovation?

Not sure. I don't know when they became a thing here- though you still get the "lightswitch" rocker locks and sliding ones by the handles common here too.

      What does £191 on eBay get you?
       
       
       
       
      An E36 BMW 316i with two sets of wheels, a DAB radio, an MOT until December, 110k miles on the clocks, a slightly* fucked back box and a bit of grot on the driver's side sill.
       

       

       

       

       

       

       
      This is co-owned between me and 17-Coffees and our plan is to do a light restoration and just generally piss about with it. It's actually really nice to drive, and is surprisingly brisk for only being a 1.6.
       
      Yes, the alloys are getting sacked off ASAP as it came with the original steel wheels with all-but-new Toyo Proxes on them!

      So many broken picture links!  I'll fix it one day.
       
      I feel I can finally unlurk properly now that I have something worthy of Autoshite to post about.

      Day One




      In the cold light of Day Two



      Came with some great features.






      The best thing about vinyl is that you *can* scrub it clean and with this old boat that was needed; everything was sticky and left a black residue on the hands. I've only been able to bring myself to spend an hour on the driver's door, the rest will have to wait for now.



      Doesn't look as big as it feels, weirdly.


      This is going to be my new daily in a few months, just got to get through a lot of cleaning and a bit of fettling. She's actually not that bad overall and only cost me £450 (plus £25 day insurance to collect her).

      The problems?
      >Quite a few rust blebs, but nothing serious or structural
      >Handbrake needs adjusting, I have to chock the wheels when parked on the drive
      >Driver's door window doesn't work
      >Probably decades of hand grease and silicone spray, built up in alternating layers. The engine bay is cleaner than the cabin.
      >Bonnet rams don't hold up the bonnet.
      >Neither do the boot rams.
      >Garage fitted electric fuel pump has no supressor, interferes with the LW/MW radio
      >PYE tape deck needs new belts, music played on it sounds like it's underwater
      >Bad previous respray with water contamination.

      But you know what, none of that matters. She's supremely comfortable and with some TLC over the summer should be in fine fettle. I'm not sure whether or not the people that look with face agog and jaw slack as I drive past are impressed, worried or amazed that a beige Princess with a brown roof still exists and is out on the road with someone a long way from pensionable age driving it.

      Well I've been meaning to sign up here in forever, but kept forgetting. Thanks to someone over on another forum I frequent poking me about it recently the subject was forced back into my very brief attention span for long enough to get me to act on the instruction.

      I figure that my little varied fleet might bring you lot some amusement...

      So...we've got:

      1993 Lada Riva 1.5E Estate (now fuel injected, as I reckon the later cars should have been from the factory...).
      1989 Saab 900i Automatic.
      1987 Skoda 120LX 21st Anniversary Special Edition.
      1985 Sinclair C5.
      2009 Peugeot 107 Verve.

      Now getting the photos together has taken me far longer than I'd expected...so you're gonna get a couple of photos of each car for now, and I'll come back with some more information tomorrow when I've got a bit more time...

      Firstly...The Lada. Before anyone asks - in response to the single question I get asked about this car: No, it is not for sale. Took me 13 years and my father's inheritance to find the thing.


      Yes, it's got the usual rusty wings...Hoping that will be resolved in the next couple of months.

       






      Next, a proper old Saab. One of the very last 8 valve cars apparently, and all the better for it. I've driven two 16v autos and they were horrible - the auto box works sooooo much better with the torque curve of the 8 valve engine. Just wish it had an overdrive for motorway cruising...









      Next up a *real* Skoda...back when they put the engine where it belongs, right out the back. In the best possible colour of course...eye-searingly bright orange.







      Seat covers have been added since that photo was taken as it suffers from the usual rotting seat cloth problem that affects virtually all Estelles.

      Then we have possibly the world's scruffiest Sinclair C5...



      Realised when looking for this that I really need to get some more photos of the thing...I use it often enough after all! We have a dog who's half husky, so this is a really good way of getting him some exercise.

      Finally - again, I really need to take more photos of - we have the little Pug 107.



      Included for the sake of variety even if it's a bit mainstream! First (and probably to be the only) new car I've bought, and has been a cracking little motor and has asked for very little in return for putting up with nearly three years of Oxford-Milton Keynes commuter traffic, before finally escaping that fate when my housemate moved to a new job. Now it doesn't do many miles and is my default car for "when I've managed to break everything else."

      I'll fill in some more details tomorrow - I warn you though that I do tend to ramble...
