Re: new to the forum! looking for Rockwell knowledge

As a VFD user and not an expert. Using a 1 hp vfd to power a 1/2 hp motor sounds good to me. More vfd hp than motor hp has worked for me in the past. More motor hp than vfd hp experinces have not worked as well. As of which one thats a harder question.... I have bought used name brands, new cheapo C...

Re: new to the forum! looking for Rockwell knowledge

How to get power can be a hard decision. Initially I went with a VFD for my first 3 phase machine. The problem with a VFD is each 3 phase motor needs a VFD. When it came time to power a Famco mill I learned there are 2 3 phase motors and they can not be powered by a single VFD... A rotary phase conv...

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

Even more stuff no one mentioned about casting.... 7) Buying casting parts and materials from Amazon can be iffy. Some great and lots of complete disappointments. Not to knock imported items.... But my Amazon Cheap thing record is poor to say the least... The mounting end of the thermocouple I bough...

Re: New to me furnace and new problems.

There were 4 new crucibles in the deal, 3 #8 crucibles and a #10. And 2 new silicon carbide plinths
The #10 is a tight fit but it does fit.

Re: How about some examples of good casting tooling.

Thank you for the pictures... And ideas. I settled for somewhat of a combination of both examples. Pictures https://imgur.com/a/DZM825T The first try was with 1/2" pencil rod....

Re: New to me furnace and new problems.

Thank you for your reply.... I found the problem last evening. Firing the furnace in the dark provided the clue I needed. The propane was not regulated. Flames were invisible in day light but at night they were several feet above the vent hole. Im guessing the flames burning outside of the furnace c...

New to me furnace and new problems.

I found a Pyramid #8 furnace in new unused condition. When running molten metal comes out of the vent. https://imgur.com/a/34PwyYv Adjusting the gas or air does not seem to effect the problem. Opening the lid partially fixes the problem. Pictures on the internet suggest the vent is small. Any sugges...

I had been using the simple loop and the pictured tongs for a #4 crucible very comfortably and successfully.. Here are the pictures. https://imgur.com/a/G8LT8fb Recently I acquired several #8 and a #10 crucibles and need to improve my tooling. A #8 crucible with a loop is no where as easy to use as ...
