    Model Diesel: 32mm bore, 38mm stroke, indirect injection

    Thanks for that information. You seem to have a reasonable selection of materials to choose from, which is always nice, and of course we all have our favorites. I don't know if there is much advantage of ductile over gray iron for the liner, one way or the other. The high silicon alloy for the...

    Ball Hopper Monitor - Casting Project

    Nice conversations going on here. A pleasure to watch. But Pat, no google? You already use youtube. You could use a vpn and incognito mode, or something like that. No offense intended, and no answer required, LOL, just yanking your chain. ;) Lloyd edit P.S. I have been resisting the...

    How not to Do Backyard Metal Casting

    Just one comment, based on personal experience. I hope you didn't steal that muffin tin from the kitchen cupboard! I took (and kept) an old worn-out one (or so I thought) from the kitchen to cast some lead and am still hearing about it 20 years later. Why did I do that ? :eek:

    Model Diesel: 32mm bore, 38mm stroke, indirect injection

    I have been doing some research on material compatibility and have found many different suggestions, plus the old automotive standby selections. Just trying to remember what you are using. Gray cast iron cylinder (?), home cast piston (what alloy??), and the material for the rings (??). The...

    How not to Do Backyard Metal Casting

    Skim and post comments? Those posts are more like an authoritative white paper on the topic. Your depth of knowledge on the subject is astounding. It sounds like you could write a book on casting iron, with the perpetual myths and misinformation properly corrected, with back-up information...

    Does your pet have a metal deficiency (no, not a mental deficiency)?

    I know how you feel Bob. They are all so unique, with their own personalities, that it is easy to get attached to them. Who has a pet that they don't "talk" to?

    Does your pet have a metal deficiency (no, not a mental deficiency)?

    ........................ So does that mean you now have 3 cats that have adopted you?

    How not to Do Backyard Metal Casting

    x2 on what Joe said. I normally take safety pretty seriously. Part of the reason is that I cut a finger off on a table saw when I was 15, and didn't even know that I was doing anything wrong. That lack of knowledge of the Do's and Don't's will get you. I have still had plenty of close calls...

    Does your pet have a metal deficiency (no, not a mental deficiency)?

    Well, ok, maybe it is a bit of a mental deficiency. About a week ago I am going into my shop in the morning and there is this tangled pile of swarf just outside the door. The door is open to the house at night. Scratching my head, I remember seeing my cat sniffing around the pile of swarf that...

    Model Diesel: 32mm bore, 38mm stroke, indirect injection

    1000, I love the progress reports, and the picture of the assembled piston, rod, and bearing almost gave me goose bumps. (OK, I confess, it did give me goosebumps, ha ha. The discussion of the cam attachment is interesting. I think I tend to trivialize that sort of thing because in my previous...

    Silver soldering rod for boiler

    This is quite an interesting thread, wandering back and forth from the original question about brazing filler rods. I personally have never built a boiler and probably never will, but I am learning a lot anyway. By the very nature of this forum, I would think that everyone here is reasonably...

    Silver soldering rod for boiler

    I agree 100%. It is very good practice to build a "safe" failure point into any type of pressure vessel. A pressure relief valve, an over-pressure plug, an o-ring installed with excessive clearances, etc, etc. A failure in a hydraulic system will normally just cause an oily mess, but the kinetic...

    What have you been doing today?

    ..............emphasis added by Lloyd.......... I remember the classic line from the long running comedy series "Saturday Night Live". Billy Crystal's impersonation of Ricardo Montoban. "It is better to Look good, than to Feel good." The intake screen really sets the entire assembly off.

    Silver soldering rod for boiler

    snip ............... Excellent stuff. Thank you so much! I appreciate not only the information, but the time it took to ferret it out, analyze, and comment. As always, much appreciated. Lloyd

    10cc glow aero engine

    Wow, I was surprised by the picture in the second video with your hand next to the engine. The engine is huge! Nice craftsmanship, and I really love the cylinder liner. Very cool! Lloyd

    Silver soldering rod for boiler

    Hi Steam, Just covering your back, LOL, so I did just the hoop stress calcs for copper using 8,500 psi as the yield for the copper tube. For the 2.5" dia tube with .065" wall I got that the tube starts to yield at 450 psi. I think(?) the 8,500 psi number is ok for hot copper, but could be...

    Silver soldering rod for boiler

    Nikhil and Steam, I found a very similar reference about sulfur and sulfides reacting with, and degrading silver brazed joints that had phosphorous in the filler metal. So, if you are firing your boiler with coal or crude oil, the phosphorous-containing filler metal is not good. There are...

    Silver soldering rod for boiler

    Steam, Can you cite a reference to the no phosphorous in copper boiler brazing alloys recommendation, please ? I can only find anecdotal information, but nothing authoritative about no-phosphorous. Just very curious. Thanks, Lloyd

    What have you been doing today?

    I built this indoor plant potting "studio" for my wife years ago and she uses it all the time. She was dividing a terribly bound-up bunch of White Siberian Irises last night. You can see them in the containers on the left. The right side of the counter and the sink were disasters (like the left)...
