Battery box for C15A No.12 Cab Chevrolet
Hi Guys,
Does anyone have an original battery tray/box picture for my no 12 cab please, mine appears to be a bubba mod and I'd like to fabricate a period looking box? Cheers, Paul

If you can't read the dimensions
Hi Paul
If you can't read the dimensions just give a shout. The one thing I think is missing is the thickness of the steel, which is thin. I'll try an get a gage today. It will probably take making two boxes to get one you like. Thanks Alex for posting the link. Cheers Phil

Hi Phil,
The thickness reads as 18 gage (gauge) on your drawing. Would there be much call for these boxes, has anyone every priced up mass fabrication. Cheers Paul

I believe that sheet metal and wire gauges differ between USA and UK. I have no idea about Canada but I would assume that they use the US standards. In the UK we have gone totally metric now and the nearest (very near) to UK 18 gauge is 1.2mm. I find it easy to remember that UK 16gauge is pretty much 1.6mm and 1/16" which is nice and easy to remember. A bit of research with Mr Google might confuse this further !

Metal thickness varies......
When attempting to get the same thickness as the original actually measured sheet metal for a cab 11 we found a lot of sizes no longer were being made. For example the rear cab wall is about 19 gauge.....local fabricator stocks standard 18 gauge.....but when you take the 18 gauge home again it is not exactly right because most if not all suppliers/manufacturers are producing under the metric system..... I still buy 18 gauge since that is the language the old metal fabricator sues everyday.
A bit like buying a wooden 2x4 inches which turns out to be 1 1/2 by 3 1/2 but I still refer to a sheet of plywood at a 4 feet by 8 feet even though ithas a metric size sticker which I can never remember. For CMP measurements I prefer the old inch/foot measurements and anything close to 1/16 to 1/8 is accurate enough...... 2B1 cargo boxes I have all have different width and lenght but all within 1/8 to 1/4 in variance. For smaller items like a battery box using the metric scale and marking cut off and bends using a sticking knife or carbide pointer is much better than using a 1/8 wide magic marker. Grant and I reproduced 3 battery boxes for installation behind the running board/driver's side. We had and original to copy the design concept. We sued similar gauge steel BUT worked backwards from the size #34 battery case that we intended to use in 12 volts. We copied the spot welds and bends but did not incorporate grooves in the bottom plate. We were fortunate to get Grant Dad to do copies of the original large brass knobs fasteners. In all it took us 2 days at two guys to produce 3 boxes that are very accurate....even forged our own theaded rods for the cover stays. Under the cover the battery is held in place with a iron angle perimeter frame then the cover fits over the whole assembly. The bottom tray was heavily coated with POR 15 to minimize corrosion and we found at Summit battery felt pads saturated with baking soda..... they fit under the battery and serve as a vibration pad and will neutralize any small acid spill. To produce them commercially on a small scale, we estimated it would be near $100 each for parts, paint and minimum time to break even...maybe cheaper at $80 if we got really good at it by repitition...... it is our opinion that at that price they would not roll off the shelves. Besides 3 was fun and we have a spare......highly repetitive work would become tedious I am afraid. Cheers

Agree on 18 gage
Hi Paul
I would strongly suggest making up a template box out of cardboard to figure the bending sequence and to be sure the battery you plan to use will actually fit. My Pat 12 battery box was missing the hold down bracket. It is very hard to get the battery in and out because the case is tight fit. My solution was to put a length of seatbelt webbing under and around the battery as a grab strap. Also because of past experience with battery terminals hitting the top of metal battery boxes, I've covered the top of the + battery terminals with a rubber sheeting. Cheers Phil

Thank you Phil your drawings worked out a treat. As you advised I made a cardboard template first to make sure everything was working out, I added 10mm to the height and 10mm to the length to give my modern battery a little wriggle room. 18 gauge is fine but I incorporated a safety edge to the top of the box and lid which gives the box some rigidity. I've omitted the battery locating bar but instead added a couple of bolts with nuts to look the part.
The latches and hinges are off the internet, thank you China and I've used blind screw rivets (that are meant for brief case handles) as fasteners. What a shame I have to paint it now. Thank you all for your advice. Regards, Paul
