Anna Bobisuthi Posted April 6, 2014 Share Posted April 6, 2014 I'm trying to set up my forge, but I'm having a problem with my high pressure regulator. I have a 0-60 psi regulator, but when I was doing the leak test the propane just seams to be coming out this small hole in the side (see picture.) no pressure reads on the gauge, and it seams to be just a continual stream out of the hole. I'm not sure if it's a rubber valve inside that's failing, or if it's some other problem. So my basic question is: Is there a way to fix it or should I just get a new regulator?

Rich Hale Posted April 6, 2014 Share Posted April 6, 2014 Most regulators have a diaphragm inside and when those leak the lpg exits that hole...Does not look like it is made to be rebuilt.. Link to comment Share on other sites More sharing options...
Frosty Posted April 6, 2014 Share Posted April 6, 2014 Welcome aboard Anna, glad to have you. If you'll put your general location in the header you may be pleasantly surprised at how many of the IFI gang live within visiting distance. That's the relief hole and propane is NOT supposed to come out of it, it just vents the back side of the diaphragm so the pressure side can move freely. If propane is leaking out of it, that's exactly what it's doing, leaking. The reg is shot, time to buy a new one. I don't know what setup you're running but most forges don't need more than a 0-30psi regulator. Most of the people running a 0-60 do because that's what the supplier had in stock. That isn't something to worry about so long as it's a good reg. Frosty The Lucky. Link to comment Share on other sites More sharing options...
ianinsa Posted April 8, 2014 Share Posted April 8, 2014 Welcome to you Anna, there is an old adage that says 'most things can be refurbished however some should not and yours is in the latter! Home repairs on diving and/or Flammable gas regulators may end up wrecking an otherwise perfect day ;) Ian Link to comment Share on other sites More sharing options...
Anna Bobisuthi Posted April 17, 2014 Author Share Posted April 17, 2014 Thanks! That's what I figured so I went ahead and got a new regulator that's 0-30 psi and I like it better, because it's got a sturdier knob. My one burner forge is now all ready to go! I've also got a three burner forge that was given to me but currently lacks a back and actual burners, so I need to fix it up before I can use it. The interior dimensions are 24"Lx15.5"Hx18"W would I still use a 0-30psi regulator for that one, even though it's split between three burners?

Frosty Posted April 17, 2014 Share Posted April 17, 2014 That's 6,696 cu/in volume, YIKES! I thinkyou're probably going to need a commercial high volume reg and serious burners. That's one BIG forge, especially for most of us home shop folk. Do you know what it was used for originally? It just sounds like a commercial furnace to me, smallish for a spring shop but still something like that. May we see pictures please? Frosty The Lucky.

Anna Bobisuthi Posted April 18, 2014 Author Share Posted April 18, 2014 I got it from a guy that runs a fabrication shop, he started building it but then decided to go with a different design, so it was sitting out back for a couple of years unfinished. I've been toying with the idea of making a movable back so I can make the volume smaller for when I'm not working on large pieces. He also started setting it up for a stomp lever to open the door, so I'm hoping to finish that at some point too. Link to comment Share on other sites More sharing options...
Anna Bobisuthi Posted April 18, 2014 Author Share Posted April 18, 2014 The forge that I've currently got running was actually made by my welding teacher a decade or two ago and he gave it away while going through a divorce. Then I got it and the other forge from the guy he gave it to, a quite small world! My welding teacher even still had a blower for it that he gave to me after he retired, along with a treadle hammer. These pictures don't show the blower or the special flue he made for it, and it also has cast plugs that fit in the holes for when you're not doing long pieces. Heavy as hell though. Its interior dimensions are 14.5"L X 12"D. Link to comment Share on other sites More sharing options...
ThomasPowers Posted April 18, 2014 Share Posted April 18, 2014 First thought on the big one is to put in another layer of insulation to snug it down a bit. You could always remove the layer if you needed a bigger forge later. Link to comment Share on other sites More sharing options...
Frosty Posted April 18, 2014 Share Posted April 18, 2014 Goodness, that's a monster forge, something a fab shop guy would make before he knew what he really needed. OR he made it for things he needed in the shop. I've seen a spring shop with a forge that size but they needed to fit leaf springs in it to arc. I'd have to shrink the interior a lot, Thomas's suggestion is a good one, it'll shrink it and increase insulation. A back wall would really help. Even the smaller forge is really large. What scale work do you do? Frosty The Lucky. Link to comment Share on other sites More sharing options...
