One more Classic Pressure gauge available.

Recommended Posts

Evening all,

 

im not sure if this is necessary as there seems to be a couple of gauges doing the rounds, with varying levels of success, but I completed my OPV mod on my classic this evening and the gauge is now available should anyone want to borrow it.

its just the gauge, not the complete handle as this would make postage a little excessive. Fitting to your existing portafilter is simple enough, you may just need a vice/brute strength and ignorance to break the threadlock on your spout. (I wedged mine in the gap between 2shelving units then used the handle as leverage and it unscrewed with no effort)

my OPV required significantly more than a 3/4 anti clockwise turn to bring it down to pressure, but the difference was significant.

Edit:

Please follow these directions If you'd like to borrow the gauge:

 

To anyone who wants to use the gauge, please don't ask others to add you to the list, as administration becomes something of an overhead, simply repost the latest version of the list (if there is one), with your name at the bottom.

When you're done with the gauge, repost the latest version with yourself removed and confirmation that you've posted on to the next recipient.

If there is no current list, please DM the current holder with your details, and post a message saying you've done so.

Many thanks to GCGlasgow for hand delivering this. Bit of an anti-climax though as it turns out the mod has already been done on mine (or the pump has deteriorated to the point where it is only capable of pushing 10bar anyway).

 

Anyway I'll PM itn for his details and get it posted off.

 

Thanks also to Hedgehog for making this available.

Can anyone that has done this mod tell me if the needle jumped around like crazy on their machine. I've done it myself and could only get a best guess at 10 bar static pressure because the needle would jump around at max pressure. I've seen videos where people have a nice solid needle at 9/10 bar im confused as to why/if I am special.

Coffeefalafal: The needle jumped about a bit on me too, I set it as close as I could guestimate to 10 bar. I'm not sure that it has to be THAT specific (Although I'm sure some of the enthusiastic/militant members of the forum will disagree :D). The main premise being that 15 bar is way too much. If its a couple of psi out I'd imagine you should be fine. Unless of course you ARE one of the militant members and are aiming for the God Shot!

 

I'm not sure if any of the other guys that have used the gauge had it bounce on them and have anything to add?

I thought I 'd read elsewhere on the forum about this happening. Unfortunately I can't remember what the solution was (pre fill the gauge with water, DON'T pre fill the gauge...) Might be worth a look around though.

The gauge bounced for me too. I believe it is a combination of reasons. Firstly that the gauge is not glycerine filled and there is nothing therefore to dampen the movement of the needle. Secondly the movement itself indicates air is trapped somewhere I believe I read. I believe the solution was not to fill the portafilter with any water.
