Re: The slow evoltuion of a long term plan

The feeling one gets when pouring hot liquid metals is akin to the same feelings one gets when a big truck filled with five yards of concrete arrive; it’s NOW or NEVER! I have done a lot of both, not as an employee, but a "Do It Yourselfer". I started pouring metals in the 70’s while teaching physic...

Re: How to gate and runner a car frame?

I tried some proffessional graphite coating on my styrofoam patterns, also tried other coatings, yes they helped a little. As far as gating is concerned, I prefer top gating. In the first photo below the pattern is shown with top gating in place, and a graphite coating. In the second photo is a pour...

Re: Precision machinist

In the early 1960's IMTS stood for International Machine Tool Show and it was held at the International Amphitheater right in the Chicago Stock Yards. The smell of hay, and other assorted aromas was ever present; Lathes & Mills were located where pigs, sheep, and cattle, had stood a few weeks before...

Re: New and shiny or weathered?

Here is weathered - At the Illinois Railroad Museum: Below it is new; as built (1/8th scale) from my supplied photos by Dave Sartor in the spring of 2017: The model he made for me stays uncovered into the fall, it's covered between November and April. How long before it looks like the real thing, or...

Re: Question regarding graphite crucibles

I run a small electric furnace for lost wax, and as you can see in the photo, graphite crucibles do wear down. Here is a site I buy my crucibles: https://www.riogrande.com/Product/Rio-Graphite-Crucible-for-Kerr-100-Oz-Automatic-Electro-Melt-Furnace/704037 Of course for bigger stuff I use #30 or #60 ...

Rare Earth Elements

Here is something of interest off of the AFS emails that I receive. Does this mean we no-longer have to depend on the Chinese or Russians for such elements that are used in all kinds of metal alloying. Should we dig up all the coal ash that was used for fill on the RR's and other places for reproces...

Re: Inspection Sheets: Worthless?

My Harrison VS 330TR which I bought from REM Corp. in 1994 came with an inspection booklet. Here it is, again, in case any of you want to perform such a detailed inspection. Their measurements are metric. I can only rely on the high reputations of REM and Harrison, at that time, for its authenticity...

Re: Flail Mowers?

In 1966 we bought a Jeep CJ5 and a 60" Mott Towing Flail Mower with an 18HP Wisconsin engine mounted on top. The mower shaft ran a around 3600 RPM, and you had to watch for harmonic vibrations of the shaft at certain RPM's. There were about 168 blades on the shaft, and you would sit cross-legged wit...

Re: Buying fasteners

Here are two that I buy from. I bought 20,000 10x3/4 SS SMS screws to use as spikes on our RR, and I'm down to our last few hundred, have no idea what the price will be for 10,000 more; I may be shocked. I also bought 15,000 #2 Drive Screws to use as rivets on my Turntables project, I'm building a g...
