My friend has these adjustable dumbbells and is now trying to pick up a weight set. I would prefer that he get an Olympic set but I don't want to waste his money that he spent on these, so is there any way to convert? I do have a machine shop at my disposal, and I could easily design something but it would cost almost as much as a new pair of actual adjustable Olympic dumbbells, especially since I think he would want the same type of convenience that the spin collars afford (which, btw, are 1"-5 acme threaded, from what I can tell).
