Exactly right. From 1970 to today, Harley Davidson has produced six different derby cover sizes. (Much to my chagrin, since each variation makes...
I've gotten a lot of invaluable advice from this forum over the last few years, and thought I should pop in and say hello and give an update. My...
I know this is an old post, but I'd be interested in talking to the guy. My email is jeff@omahaderbycovers.com
Interesting. Thanks for the comment. Can you describe your process more fully? A bunch of questions come to mind: - How fine do you break up the...
Had a guy come by the shop yesterday who started talking about his experience in a bronze foundry from years ago. He's an old guy who freely...
There's a guy on Instagram who goes by @frozensteel.nl who does that kind of work, in bronze. Some amazing stuff.
Perhaps, but I'd be concerned about it arriving safely. When you buy individual boxes from R&R, they double box them. These arrived palletized and...
Boxes are 13" x 11.5" x 10". This is the stuff: https://shop.ransom-randolph.com/rancast
Since it looks like I'm converting to shell, I've got a bunch of leftover Rancast (in the 44lb cartons) I need to get rid of. I'm located in...
My experience with R&R has been that they are very, very helpful when you have technical questions. I'd send them an email and see what they say.
Here's a pic. This shows the detail retention through the entire process: 3D Model -> 3D Print -> RTV Mold -> Wax Pattern -> Shell -> Boil out ->...
My assumption is that the wax being lighter than water, you want to give it the chance to float up and out of the shell. Not sure. I boiled mine...
After too much time and wasted material working with block, I decided to give shell a try. A big part of my inspiration was the "boiling out wax"...
That's nice of you to say. The good news is I checked the function of the lance before the melt had really started. Was just pre-warming on...
AND...right on schedule I aborted a melt this morning because my thermocouple died.
Not that I know of. I think the bottom line for applications like what I think most of us are using is that if you follow those three guidelines,...
He didn't say exactly in terms of clock time. I told him my practice was to hang it over the edge and wait for it to read 2000F before plunging,...
I had a conversation a few months ago with the guy who owns the company that makes the probes MIFCO sells. Good guy. Very helpful. He painted a...
That's encouraging. Appreciate it. Here's a followup question: If the goal is clean metal, does it make sense to remelt (with associated...
Just noodling on something... I put a fair amount of effort into cleaning my sprues and scraps before remelting. This material starts life as...
