Otter LRC CM4647296 comes home

[Jordan Baker]

In the first picture there is the welds visible for the flare pistol bracket. A few pictures and some mystery holes along the back panel. There is a pair near the top and then five uniformly spaced along bottom corner. The hasp is riveted on

Last two pictures with the dimensions between the wood blocks. The tray is 12” deep with the wood blocks being closer to 10”.

Photo 3 is a '37 pattern 1" brass web strap end. They used the holes in the usual eyelets for rivets that held the end of the strap to the vehicle bin. Safe to say there was a web strap attached there and a reciprocal one someplace on the other side.

Jordan.

If I understand the turret of the Otter correctly, it was manually operated by the gunner, using the Foot Ring mounted on the floor below the basket seat to leverage the basket left or right. If so, how much clearance is there below the top of the Foot Rest and the pan under the seat? Later Otter production may have taken advantage of this space for storage by adding another metal 4-sided shelf. This could even have been designed as a bolt on retro kit.

For the five holes you found along the lower rear edge, take a close look at the spacing in relation to the two wooden blocks. Is it symmetrical, or is it possible a sixth hole existed at one end once upon a time. That might be the hole line for attaching the upper rear tab of the new shelf.

If an item like Bruce suggested was stowed there, you would not want a standard padlock fastener getting in the way of sliding something in and out of that shelf. Perhaps the slot in the hasp was used to engage a spring tab retainer that was fitted underneath the floor of the new shelf assembly?

Just odd thoughts but thought I would put them out there.

I wonder if the set of Design Branch Reference Books list any Otter upgrades.

Tonight I started in on making the new tray.


Yes David, the turret was rotated by pressing your feet on the foot ring on the floor. There is quite a bit of clearance between the bottom of the tray and the foot ring. I believe it’s easily 10-12 inches. This Otter is on the earlier end of things. There very well may have been a kit but when looking over the Overloon Otter (it’s a later made one) there was no sign of these holes and wood blocks from what I remember.

There was only 5 holes. The wood blocks are off centre whereas the hasp is centred.

The armoured glass blocks have their own bins beside the driver and commander seats. The wet weather windows do not show up at all on the stowage diagrams. I thought about them going there but they don’t really fit between the wood blocks.

Nice start to the tray, Jordan.

I noticed in the photo there are Pattern 37 Brass fittings surviving on both sides of the front of the tray, that Bruce identified the other day. Looks like the open concept of that shelf in the illustration was amended to add a web strap to keep the stuff on the shelf from falling out.

Do you have any idea how easily rotated that turret assembly is for the operator? If it moves easily, I can see why things on that shelf could have been prone to sliding out.

The other thing I noticed this evening in that illustration is the two steel boxes stowed under the turret foot rest. The large square looking one seems centred under the rest, however the smaller one, strapped to its mount looks like it sticks out quite a bit away from the Rest Assembly. Are there any signs of that sheet metal mount for the smaller box being installed in your Otter? I ask because the way it sticks out into the open, I can imagine ankles and lower legs getting slammed into it in the heat of the moment when the Operator is turning the turret back and forth while focusing on things outside. Maybe...that box got moved to a new shelf under the seat tray. A similar location, but safer place for whatever it is.

That’s all I’ve got tonight, Jordan. I have run out of tea!

The three boxes under the turret foot ring are Boyes Ammunition boxes. There is no sign of ever having a shelf mounted on the floor near the foot ring.

The turret rotates on 60 1/2” ball bearings. It’s supposed to be able to rotate quite freely.

As for the 37pat web straps. These clips are steel. I’ll have to take a closer look to see what remains of any webbing inside the clips.

As for today’s progress I’m working away on the magazine bins. Yesterday I picked up a Porta Spot Spotwelder a few hours away from me. I found it for sale on Facebook marketplace. It’s been a bit of a learning curve with a few blow through holes that I will have to fix. However I believe I’ve finally figured it out and seem to be making decent spot welds.

Jordan,
I have a spot welder similar to yours and one of the best things I did was to make a copper cap that fits onto one of the electrodes. It is about 20mm diameter and long, drilled half way through to very loosely fit the electrode but still be able to rock a bit. The top of it is flat but with the edge a little rounded so as not to mark the job. Using this on the 'good' side of the job it avoids the sharp edged dimples that you get from a small spot weld. Obviously you can't use one of these on both sides as it wouldn't be a spot weld then and you do have to use a little more heat but it is easy to get really nice clean and strong welds this way.
