Re: my project

Looking awesome! What are the different materials that the castings are made of?

Material Bearing or Ball Bearing

On a 1.5" scale engine plans call for Phosphor Bronze to make the axle boxes out of. I can't find bar stock of phosphor bronze anywhere (much less small quantities). I was wondering if it was even used still with ball bearings available. Any help would be great! Thanks!

Re: Disney American

Re: Trouble with Green Sand

I did get to the bottom of the green sand problem. I didn't get to try the water method but I will next time I have any doubt. I put some wet sand on a metal plate and let it dry. Then I wiped away the sand hoping I'd see the clay still stuck to the metal. It had a very faint haze on it. I figured t...

On Charles Dockstader's website he calls his Calculator/Computer "Valve Gear on the Computer". Hence, Charlesd VGC.

Trouble with Green Sand

Hello, I have a question regarding green sand. I ordered 30lbs of premixed sand off ebay. I wanted to do it myself but I couldn't source a fine enough sand or bentonite clay. Plus it was convenient and saved me time. I got the sand and they also included extra bentonite to "refresh" the sand. I've f...

Update I think its finished unless I overlooked something. I had to tweak some things. Like you suggested Baggo. Also I tweaked some of my own. So as it stand now VGC shows correct Lap and Lead. A cuttoff of 81.6 to 81.8 at full forward gear. (Goal was 81.85.) And a cuttoff at .1/.1 at center. I th...

UPDATE

UPDATE Baggo, the link to Dan Ashtons has helped so much thank you! I believe I have 95% of the valve gear correct now. My current problem is in the valve movement itself. With the spread sheet from Don Ashtons site shows correct calculations for what I came up with. Cutoff: 81.85% or 82% Valve Tra...

Walschaerts Help ***UPDATED 3-28-2010***

I'm making a Walschaerts Valve Gear for a narrow gauge 1:20.3 model. I have took a lot of time to try to get the working proportions and keep it as close to prototype as possible. For example using a drop link, and locating the reversing arm in the correct location. I've had some success but I'm sti...

I for one am very glad you posted this. I had no idea. I don't weld but I use brake clean every day. I go though several cans a week at work. Also some other guys at work do the same. We don't weld around it but I know we've heated tooling with a heat gun and then sprayed the parts with brake clean ...
