Default Need to build a boiler for a project

I'm looking to build this for a hand drawn steam fire engine project I'd like to make. I will be having a boiler technician and a guy who has been building boilers and parts for them for over 30 years helping me with it. I'd prefer to do a vertical fire tube at 20 inches in diameter because they are bulletproof but wouldn't be opposed to a Ofeldt either in the same diameter shell. I hope the picture goes threw but I included plans for the Ofeldt to show what I'd build instead. I live in New York and I also need to know what insurance and certs I'd need to have as well thanks ahead of time!

What will be your substitute for the asbestos?

You may want to read through this online document regarding obtaining a licence for a high pressure boiler before you proceed. If you get in touch with them I would imagine they can also give you advice on what insurances you need to hold, and what inspection tickets are required.

You meet one of the criteria for holding a licence, you were/are employed as a fireman for NY.

https://www1.nyc.gov/site/buildings/...r-license.page

Insulation is a good point. A ceramic material is available now instead of the asbestos lining that would have been used. Can be supplied as a sheet, or solid formed block, ie formed to the curved shape of your boiler.

I've got to say I like the spiral tube design within the fire box. Should raise pressure quick. You also need to make sure that they will be a water tank or supply line close by to maintain the water level. But I'm sure your friend will know this already will be following your progress sounds an interesting project.

I don't know about building it full sized, but it looks like a very interesting boiler to model.

Thanks for the drawing,
Don

I'd like the shell to be 20 inches so it would be considerably smaller

Also have a search for "Merryweather" boiler or steam pumps. They were an English maker of hand drawn fire pumps.

https://www.gracesguide.co.uk/Merryweather_and_Sons

This is one for a 1/4 scale model but gives an idea of the tube layout.

So is that technically a water tube boiler?

Here is a photo of that same boiler filled and fired And how does this guy get away with selling these because there is no way he's a code shop http://m.ebay.com/itm/Steam-Engine-B....c100408.m2460

Steampower88:

Caveat emptor? Let the buyer beware?

A document, needing to be signed by you and notarized, stating the neither you, your relatives, your neighbors, or any passers-by, or their friends and relatives, can sue him - before you get the boiler. One that is valid for eternity?

Or maybe just a simple document, again signed by you and notarized, stating that YOU are accepting ALL responsibility for the design, construction, and maintenance of this boiler - before you get the boiler?

Or then again maybe the builder hasn't thought about his liability? Or he just doesn't care about getting sued?

Don
