Re: Consequences due to lack of penetration because of inexperience welders.

Here is a case of poor civil engineering, it happened just a few months ago.

Probably cost several million to correct:

Re: casting in the third world

Third World was our world in 1906!

Photo #1: Below is a 1906 Photo out of a book on crucibles, how many OSHA violations can you find.

( I had put this on before.)

Photo #2: Here are Ean and I dressed to make OSHA happy!

Re: Fed up With Crummy Rotary Tools

Way back, I think Dremel had their factory in a suburb north of Chicago (North Chicago?), I remember their service was very prompt and correct. Today they are in Racine, I might think of driving that far, but I usually will buy a newer model, if it goes bad. Google: "dremel factory store" to read ab...

Re: Fed up With Crummy Rotary Tools

Here is a company that has a large selection of rotary tools, but their prices are not the best.

I have bought from them many times, and they do have a printed catalog they mail out on an almost monthly basis.

Patterened Sheet Metal

In an ad from Rio Grande, they had some patterned copper sheets that may be of interest:

The gold sheets are too expensive.

Re: Baking Cores

I have never baked a core, I use the CO2 (Carbon Dioxide)- Sodium Silicate method for making cores. It's a "Cold Box" method and requires no heat. There is no toxicity/fumes associated with this method. I usually will mull 400 milliliters of Sodium Silicate with 25 pounds of sand. I use AFS 105, but...

Re: Rough strength equivalent

Several years ago, a relative of mine was in maintenance at a paint company when they got rid of shelving that held heavy skids of gallon paint cans. He gave me several dozen of the ~ 10ft long rectangular tubing that held up those loads. They are almost the exact size of a wooden 2x4 and are 1/8th ...

Re: Things they dont tell ya when you start casting. :)

As I wrote in previous posts, I started with greensand in the night school class I was attending, and then when we switched to the other shop with Petrobond, I was convinced it was for me. I used that shop exclusively for many years, because I had a special permit even tho the night school had long ...

Re: New tool for Train Mountain

Looks like a great solution to moving switches, sorta analogous to that German video were they are putting down concrete ties and welded rail. I do not have hundreds of switches to move, so when I fabricate one, I use my Toro Dingo TX427WT with either of two attachments, I fabricated for it, to move...

Re: Apple Mac laptop

I’m a long time Apple user, started with Apple IIe when they first came out, then Apple IIgs until 2002 (17 years). Had no Internet, so to get it I bought a MAC G4 in 2002. It is still running but only for Photoshop CS2, I do not need to pay their cloud fees! Last summer I purchased a MacPro, partia...
