Thread: Help needed in finding info and eng. drawings on this 2-2-2
09/05/2020 13:56:11

Thank you all for answering so far.

I apologize for missing the dimensions as I was focused on trying to add photos in the same way as I do on the Vintage Computer Forum but found you have to add them to an album here first. Plus with flaky Mobile Internet due to the heavy rain all day I was trying to get the text worded clearly.

10.47pm and I just jumped out of bed threw on 4 layers inc wet weather gear over PJ'S, dashed to my workshop, measured and now back in the warm house.

Its a 5" Gauge engine.

all the next dimensions are approx just done by eye with an old timber ruler.

Main Drive wheel is close enough to 6": diameter

Crank throw is about 1": so about 2":"piston travel

Lead and trail wheels are zbout 3.75" dia

Frame is about 20.5" long by about 7.25" wide

Thanks for the help and links and suggestions

regards

David

Hello everyone,

apart from my introductory post a few days ago this is my first post here and asking about my 2-2-2 chassis is actually one of the prime reasons for joining.

The reason behind my questions

I wish to get it operational as a rolling chassis so I need to make some missing parts. I assume it a UK design and that I could find some drawings for it and possibly some advice on the best method to make the missing parts.

Reasons for not making a boiler is I just wish to have it 'run'':-

1. on low pressure compressed air to use in STEM classes for Primary Schools I visit. I will write more on this another time.

2. personally at home to use on compressed air at a pressure comparable to what would have been its operating steam pressure.

Background

So I have a 2-2-2. Missing the Conrod Big end + connections to the cranks and the main axle spring blocks.

I got it from a Scrap Metal Yard where it was there along with a lot of other engines (some complete).

Yard owner said a young girl drove a car in with trailer, said ''this junk was from her Granddads house", and she wanted money for it.

I asked what they paid pretending to be curious more than interested. Indian/Pakistan guy worker said scrap metal value, of course, nothing more !" Grudgingly she accepted it.

I got this engine, less the boiler as copper scrap was paying serious money so they wanted to keep it. I offered double scrap value, but guy said I was lucky to get the metal chassis as their rule was NOTHING leaves yard except in the BIG Bins.

Few Facts

  1. I am 69 this June 2020 and have NOT retired
  2. I was an apprentice trained as a Caterpillar Diesel Technician and also trained and worked for Rolls Royce Marine Division as a senior service engineer.
  3. Was taught pattern making and foundry casting at RMIT technical College. Also, hold Uni Post Degree qualifications in Robotics and Automation.
  4. Owned my Hercus 9" Model A lathe for now 40 years and used it throughout those years.
  5. Have a small mill (not Chinese) that uses chucks and collets from the lathe
  6. have a small hand shaper
  7. a home workshop size moving bed vintage planer
  8. and a huge selection of the necessary hand tools inc taps & dies Whitworth, BA, Metric SAE, and some weird instrument threads.
  9. an assortment of air and electric hand and pedestal tools
  10. and measuring tools inc gauge blocks, reamers mikes etc
  11. Yes, I also have a 3d printer.
  12. But have limited space in the area where my lathe etc is located.

Conclusion

I have a limited number of old back issues of Model Engineer from the 1940's but when I looked at them 6 years ago I did not see any hint of this engine or one similar.

I will try and post some images that I have stored on the site IMGUR dot come

Hopefully they show ok here?

(EDITED here and removed the 4 image links as I found out about the Album function. and I have posted one image per post following)

I trust someone here can assist me.

Stay safe and keep well in these trying Covid-19 times

Thread: Greeting from Polymath living in Melbourne, Victoria Australia.
03/05/2020 11:42:04

Hi all,

Having been both a Model and Full-size engineer since my early teens and 20's I have often read Model Engineer magazine and Engineering in Miniature.

A little on me as an Introduction.

My peers call me a Polymath as I have so many diverse interests, yet connected via both the physical and natural sciences plus maths/

I am Caterpillar trained Higher Diesel Technician plus 5 years night schooled to qualify as an Industrial Electronics Technician. I went on to Monash University (Melb Aust) and completed a Graduate Diploma in Robotics.

Have both a 9" lathe and a jewelers lathe, milling machine, Shaper and Metal planer, and the normal collection of Pedestal and hand drills, grinders, welders, and hand tools + measuring instruments. Inverted metallurgical Microscopes, early magic lanterns, and other scientific instruments.

Plus own a +1000 book library dating from 1700s to early 20th century covering Steam, Geology, Motor Cars, Astronomy electrical engineering, and medicine.

Pic, if it is permitted in this forum section, is the more vintage part of my electronic workshop.

so that a quick intro to me whom is turning 69 this June (2020)

regards to all and stay safe from Covid-19
