Is the 100psi max warning, in the instructions for the cyclone blast cabinets (e500 specifically), a true number or is it something we can fudge a little? If so what's top end? 110, 125, etc? Obviously I want to stay safe but the results got better with more PSI so I want to keep going past the 100 I stopped at.
Not for a critique (wrong forum) but for illustration here is my first blast (a nose warmer):
I used the nozzle that came with the cabinet for the above but for my next one I'd like to be craggier and I am going to try a smaller nozzle. I'll use the smaller nozzle while staying at 100 for a go, on some yard sale pipe, but can I crank the PSI a little more too?
Fast, quick, accurate answers, you guys rock - thanks!
I wanted to get one pipe done, so I could say I have done it, but now with your feedback I am going to go to town. So all my shop pipes and the $1 garage sale ones are gonna get blasted and we will see in a few weeks how the next new pipe comes out.
Usually the limits on those type of things are like 300% of the posted safety zone. That's not to say that you can do as you please, but 105 psi is functionally very little different than 100.
Now, things happen fast at these pressures, have a look at your system and if there are things you think maybe won't take it - plastic hoses without much reinforcement etc, replace them with a larger version....
I ramped up to 140 the other day on mine and got a really nice result.
I'm rated at 175 from the tank to the blasting cabinet so that's really good info as I feel comfortable cranking it up and seeing what happens. From what I have seen with my set up I got a hunch ~120, and one size smaller of a nozzle, is going to be the sweet spot, but only having a couple goes will tell.
Yeah go to your smallest nozzle and see what happens.
Also if you only have glass in there, while it's new (sharp) it will cut but that will slowly fade, so you might want to add some other media for punch.

What have you done with Todd?! That picture is way too nice. The pipe is believable, but you gave yourself away with the pic. Poser.

My kid loned me her Wunder-Camera. I hate it, don't know how to run it, but even in it's most basic, dummy point-and-shoot mode it's gives better pics than I've ever managed with all kinds of fiddling with my crappy old A480.

Wait a second, who's this douchebag that stole Uber's Avatar? I liked Ubie and now we have an imposter who almost believed that....
wait ...man this is confusing! Next thing I know you guys will be trying to tell me that girls are making pipes too?!?!

Oh, er, uh, Hi Scottie!
seriously though thanks for the info, I spent every nickel and dime I've saved up from pipe making over the past couple years, including my corn cob days when I first joined the forum, to get all the needed parts for a blasting set up, and now to be honest I was just a little worried I would break something that I couldn't afford to fix. It's a family\no pipe making weekend for me but I am gonna sneak out to the shop a couple hours and play with the nozzles and pressures and see what I can do
Your cabinet does not really come into effect for the rating. It is going to be the nozzle that you are using that is rated for certain psi. Smaller the nozzle lower the psi rating usually.

Thanks Premal, I assume the prime reason for the rating on the nozzle is that the nozzle will wear and in time open to a larger diameter. When I was doing my homework before purchasing the parts and pieces, I also ordered a set of tungsten carbide replacement nozzles Rad had recommended in a several years old thread. So I should be good to go by that account. I didn't have them for the blast in the original post but will be using them now.

Not at all Scottie, not at all, I was just having a little fun on what to my early shift working butt, is Friday night

I am not sure if Rad has changed his carbide nozzle out yet, but he does make about 3 or 4 times many pipes a year than Bill and I do combined. I have had the same carbide nozzle in my system since 2008 and it is still going strong after about 500+ pipes being blasted. I think I am going to get another 500+ out of it before it has to be changed. The air jet inside the nozzle has to be changed about once every 100+ pipes. This is for siphon feed systems. For pressure feed systems you have to keep a closer watch on the hose and internals.
