The website closed a couple weeks after we all ordered our kits I believe.
I also got refunded after opening a case through PayPal.
I did search O’Keefe casting company, and found some information that would appear to indicate it’s a legitimate business, and has been around since 1962. But it’s listed as a place that does aluminum castings, while the website we all used didn’t mention anything like that.
Since this thread was labeled as such, I also tried to order a machine vise casting from college engineering supply in the UK. It took about 2 weeks for them to reply by email that they no longer offer the kit #565. So that ones a no go also, for anyone still trying. They may have others. Their reply didn’t say so. But you may spend a lot of time waiting for a reply from them to find out.
