I'd guess the round bolted plate would be in case someone had to get into the tank to clean or repair it. Thing hat botheres me is theres no fill spout on top of the tank or a vent. The tank was probably filled from barrels or a truck with a hand pump. The farmers around here had wooden tank wagons with a big mansize stick on a pump to keep the threshing engines watered up. I used a smaller rig as a kid to fuel our tractors on the farm back in the day.Took about 5 min. of pumping to transfer say 30 gallons. BILL
Thanks mate for the feedback. I decided to send my message offline to a few guys and recieved additional info. I'm currently sitting at my modeling desk creating a number of oil tanks, all with fill inlets.
The thing that surprised me is that I looked thru hundreds of my photos and only had a few prototype oil tanks. You would thing that every workshop needed oil's..
Much better , but they still need a vent pipe. It'll be a pipe about 10 inches high and 1 1/2 " - 2" diameter and shaped like an upside down J. This will allow fuel to flow frely out. I have seen tanks that have cllapsed from improper venting. Also some filler caps and outlets may need a locking device to prevent fuel theft. My freind in Alaska still uses #2 diesel oil to heat his house and over 250 gals. were stolen last winter while he was away. Diesl was about $4.25 then. Bill in Idaho where fuel is not quite so expensive. I know, us yanks are spoiled.
Relly like it mario. Ill be adding that picture to my folder of detail ideas. Will be just the thing to have next to my blacksmith shop. What scale is this in? (always hard to tell when you have a few projects on the go).
Adrian. With some of my detail projects, I'm not sure what scale they will be until I'm near completion. The Nolan Tanks are now 1:35. At some stage I'll make similar in 1:48 & 1:24 scale with a few variations.
Bill. Thanks for the info regarding locking caps.
Rick. There are so many details I hope to reproduce from Brian's work.
