Thanks BattyZ
I’m still waiting for the CFB to become available, so rather than just wait, I decided to go ahead and build some of the bits I’ll need. I will...
Thank you for the tip. I’ll give them a visit tomorrow. Thanks again. Jim
I spun up new less restrictive manifolds and painted the flask vibrating rig. I got this sand from Maynard’s. It was the only dried sand they...
When I round up some sand I’ll test it per your recommendation. As I fooled around with it some more I concluded that my air supply was too...
I built a vibration table for compacting sand around lost foam patterns. Here are some pictures: The base is 1” x 2” rectangular tubing. It holds...
Thanks for noticing the arc. That was fun to make. I have a Bridgeport and a 10” rotary table but that arc has a 12” radius, so I clamped a...
I also built the controller I plan to use for the furnace. Attached is the circuit I finally used along with some pics of the completed control....
Since I am waiting for receipt of the CFB I decided to build some of the bits I will need when it gets here. My primary interest is lost foam so...
Just heard from Inkbird and they said the ITC-106 VH controller would drive 2 SSR’s in parallel. Time to redraw my schematic, again. Thanks...
Haven’t heard from Inkbird yet. I’ll give them a few more days. My SSR’s also accept 3 to 32 volts dc input but don’t have a current...
I have an Inkbird ITC-106VH PID. I also have a second Inkbird SSR-40 DA. Originally I considered driving both of them in parallel with the PID,...
I can do that. Thanks Jim
I decided to build a 6000 watt electric lift off furnace. 10 inch inside diameter, 14 inch outside diameter by 15 inches tall not including the...
Thank you. Sorry it took so long to get back but I’ve been out of the country and the internet was at best spotty. Happy New Year!
Thanks for clearing that up for me. Appreciate it. Jim
Thank you for the feedback and advice. After having read the heating element design handbook you referenced I found out that 3/16” id is too...
Thank you for sharing your expertise. I wound a test piece of #14 Kanthal A with a 3/16” ID. I was really surprised at how well it worked. No...
I am totally new to casting. The only experience I have is making lead sinkers as a kid. I can’t believe my dad let a 5th grader use a gasoline...
