    Optimal number of boiler tubes.

    Thanks, Ken, for sure I am going to run at least one coal fire, probably more. I grew up in the steam train era, as probably you did also. Wallsend is just south of the Newcastle to Edinburgh line and remember seeing the trains flying along, smoke, fire steam, and great noise, every schoolboy...

    Taper setting device

    Do you have anything with an MT2 taper? Set it up between centres and indicate from the compound.

    Optimal number of boiler tubes.

    Here's my baby running on compressed air. This is the blub from the PM Research website This is not a scaled-down model, but a full-size working steam engine. It is a replica of a rare old steam engine used for various small portable power applications a century ago. This engine was sold as a...

    Optimal number of boiler tubes.

    Here's what I'm proposing to do, a ring of copper soldered around the door between the inner and outer wrapper. Probably hold it in place with screws until it gets soldered..

    Optimal number of boiler tubes.

    If I were to go with 4 superheater tubes would they be connected in parallel or in series?

    Optimal number of boiler tubes.

    That may be difficult to get if at all, the thickest I've seen is 16 gauge 1.6mm. I have a book by Alex Wiess "Making Small Gas Fired Boilers for Steam Models" in which he uses 1.6mm copper for everything. I can get 10ga for the main boiler tube and the firebox as well as the tube plates.

    Mini Lathe belt slipping

    What I did with my Minilathe, I welded together a couple of 2" x 3" steel beams, got them as flat as I could, then poured epoxy where the lathe feet would be and placed the lathe in position, not bolting it down yet. When the epoxy had cured I bolted the feet down. I used anchoring epoxy, it...

    Optimal number of boiler tubes.

    I think I'm sticking with the original plans, 55 7/16" flues. The only deviation, at the moment, is to use an oval firebox door after reading of failures with rectangular openings. I do like the idea of a superheater whether smokebox or firebox, I didn't quite understand tenor's description of...

    Stuart 10H build

    Is that a casting kit or from scratch?

    Optimal number of boiler tubes.

    I have heard back from one of my local model railway contacts. According to him, although he will deny it in a court of law, boilers below a certain size 10" and pressure 100psi do not need to follow any regulations. As Steamchick put it, "you are free to build your own bomb". I'm still...

    Optimal number of boiler tubes.

    Actually, I'm basing my calculations on running at 60psi, real-time results may vary.

    That was just a copy-and-paste from the spreadsheet that Quinn Dunki "Blondihacks" produced, available to her Patrons on YouTube for a small monthly donation. I don't feel comfortable sharing without her blessing. Sorry Ray

    Optimal number of boiler tubes.

    Steamchick, thank you for taking the time to teach this old Geordie a few things about boilers and requirements. I like how you are making sure that I build a SAFE boiler. After much soul-searching, I have a few options I think. 1. Give up, not happening. 2. Use a round firehole, it seems that...

    Optimal number of boiler tubes.

    Macc Models have 1/8" 3.175mm 6" and 5" tube that I was planning on using. Certainly a lot to think about.

    Optimal number of boiler tubes.

    Steamchick you make an interesting, if not terrifying, observation there. There is a ring around the base of the boiler shell that should/maybe resist any outward pressure. But the inner firebox is simply relying on a silver solder joint. I wonder if an inner ring were placed inside the firebox...

    Optimal number of boiler tubes.

    tenor thank you for another thought-provoking post. I am/was intending for smokebox coils but you have made me rethink this. One point though, from your photo it looks like it has one tube down the middle, would that not defeat the object of using flue gases to heat the coils? There are no coils...

    Optimal number of boiler tubes.

    There's a lot of information from both Steamchick and Tenor and Charles Lamont, some of it beyond my ken, I have to read it several times to let it sink in. Thank you all for taking the time to impart some of your knowledge and experience to me, I really appreciate it.

    Optimal number of boiler tubes.

    "And a "wire-wool" Propane burner, around 8kW," As soon as I saw this burner of yours I thought this is the one. If I stay with the sized firebox door I am limited as to the size of burner. However, if I wanted to run a burner I could remove the firebox plate and come into the chamber from...
