We've been grooving some 4" copper at work. Did some at school and have done it in the past when I did the 4" main in the other hallway as well as in another building too. We're putting up water mains in one of the hallways. Not brain surgery by any stretch of the imagination, but I'm just wondering if you guys have any tips as far as grooving is concerned. We run I think it's a Ridgid 915 Groover on a 300 power vise. Using 12 foot lengthes of Type L Copper, we have the Copper roller/groover adapter kit (or whatever it's called - different components) installed into the groover. Generally speaking I usually set up the pipe stand so the pipe is level, and I offset it so the end of the pipe (the end opposite the end in the groover) just to the left and put the power vise on reverse. This way it won't back out when you start it (why I put the pipe just to the left slightly). But every now and then you get a warped end or a burred end. I make sure I go really slowly with the grooving as far as pulling down on the handle as I understand it takes a while to turn the 4" pipe. I figure that making sure the pipe is level helps as it, in my thinking anyways, seems to not cause the end of the pipe to flare up when the groover edge bits down into it (and I use the term "bite" loosely here - I go slow like I said). I'm not having problems but I just want to reduce the "every now and then" to Nil. In fact it's usually not me who has the problems with the groover but a less expiereinced co-worker. Any fool proof tips or thoughts to offer? There doesn't seem to be much talk as far as grooving is concerned either on here..so maybe now is the time? (grooving for victaulic clamps).
By the way I am a firm believer in properly lubing your Victaulic Clamps gaskets. I know some don't, but it is so much easier to work with when lubed plus it prevents potential pinching of the gasket.
Another Q I have is what is your guy's preference as far as cutting the bigger Copper (3" plus) pipe? I have a set of Ridgid 118 Midget cutters, Ridgid 151 quick acting cutters (1/4" to 1 1/2"), and the Ridgid 153 Quick acting cutters (1 1/4" to 3 1/8") so I am covered up to 3" pipe. I was thinking of getting a set of 154 or 156 quick acting cutters (I think the 154's are 1 7/8" to 4 1/8" and the 156's are 4" to 6 5/8"), Or is there a low burr chop saw blade you guys might be able to recommend for Copper pipe? We are currently using a Chop (or "abrasive cut off") saw with a carbon blade. It's not the best as it takes a while and leaves burrs (which I file out, but hey if I can find something that works better and makes the chop saws job easier then...) but it seems to do the trick ok. The nice thing I will say about all the cutters I own (the 118, 151, & 153) is they all use the same cutter wheel so buying replacement's is always nice.
