    3” boiler project.

    You gave me an idea. I need to sketch this out. Thanks!

    3” boiler project.

    I was wondering if someone was going to comment on the fish tank hose. I will install an insulated hard line to the base with a solid mount to avoid any stress on the boiler Itself. I’m deciding on a means of connection. A flange mounted to the boiler base would be simple enough with the same...

    3” boiler project.

    I actually finished the layout board. Model clay bricks were intended to provide insulation between the burner and the base board. After running a while at a full 50psi, I could touch the boiler and base board without burning my fingers. I just reworked a rather problematic PM #3 from E-Bay...

    Yarrow design.

    I’m outlining a design for a Yarrow boiler. I have a 14” length of approx. 3” OD pipe left over from my vertical boiler. I’m thinking 1.5” OD for the two lower drums. One of the factors will be my ability to make a swedging tool for the tubes as I have to reach into the main drums to deal...

    Clarkson Vertical Steam Engine 1” bore

    Making progress on the horizontal Clarkson. I opened the box and made copies of the original drawings.

    3” boiler project.

    I updated my folder. Thanks! This has been a learning experience. I am sketching out a horizontal boiler around a remaining 12” length of the same material used as the shell for this project, but have not done the calculations yet. I’m deciding on either a fire tube or a Yarrow type. The...

    Clearance fit 1922 Dodge water pump

    I think you hit on the fix! You never know what you will find after 100yrs of abuse and home farm repair. The cross drilled holes were added at some point . The impeller is not original either but will work. I cut a keypad and will press it into place. Filling the wear spot was interesting...

    Clearance fit 1922 Dodge water pump

    Ran into an interesting project. A friend of mine has a 1922 Dodge and asked me if I would look at his leaking water pump. He thought some new packing would do the trick. I told him that I did not think there was enough packing on the planet to seal this shaft. It was rather hysterical and...

    3” boiler project.

    Thanks for all the help. This was a very satisfying project.

    3” boiler project.

    I’m not allowed to paint it so cleanup after use will take some time. I would like to find a propane tank to fit on a board layout, but I have only found butane or mix versions.

    3” boiler project.

    Thanks I just purchased it.

    3” boiler project.

    I initially calculated the thicknesses from my reading and was concerned since this was my first boiler. I am fortunate finding this group as this the first to actually respond with technical comments. Í have much more information for the next build this Summer. I try to include an artistic...

    3” boiler project.

    I’m a software and electrical engineer. We live in cubicles protected from the elements. Coupled with the fact that my hair does not turn gray, but rather falls out in shame makes 60 look pretty good. Oh yes,... my pop made mom a frying pan from melted down automotive pistons. Nothing like...

    3” boiler project.

    I was basically making fun. I posted a Facebook photo and I was asked if it was a cappuccino machine so of course I could not resist saying yes. My next project will be the horizontal version of the Clarkson vertical I posted and a 3” horizontal boiler. I’m deciding if I should go with a fire...

    3” boiler project.

    Just gotta ask. These things are copper brazed with silver. I have some stainless steel and a tip from a cappuccino coffee maker wand. I would think such a boiler would be safe for food.

    3” boiler project.

    Thanks so much for all the help. This was my first steam project and the thought of a 50lbs steam vessel in front of my face was a bit unnerving. It helps to have someone review point out potential trouble spots and plain screw ups. I will take care of the pop off valve as you suggested and...

    3” boiler project.

    I have room to open the hole and will check to make sure the blow off valve can keep up.

    3” boiler project.

    I am basically becoming a reformed software and electrical engineer. I started working in 1982 with side businesses doing textbooks and running a clock and instrument repair home business. I am ready to retire.

    I have 4 years to go.
