I'd like to gather peoples thoughts on how they would improve upon the Ridgid 300 and other threaders. I spend alot of time running these machines and though the 300 is a pretty solid machine, I think a few changes might be in order. We have a number of rebuilt machines at work and they all seem to have an aluminum wheel on the vice. Any weight savings are only marginal and they do not clamp down on the pipe very well at all. The iron ones are far superior. I would also like to see Ridgid come up with a more secure way to connect the handle for the carridge to the machine. The original piece that slides over the arm usually breaks within the first few months and is replaced with a beam clamp. The eye bolts underneath the carridge break easily as well. I just wanted to get some ideas and maybe see some modifications that have worked for you.
