  1. Hello everyone. So heres how I fixed my problem. After much huffing and puffing I ended up investing in a proper forge blower from glendale forge a manufacturers here in the uk. Hello everyone.

Neither had enough pressure (though ample CFM). I thought it may be my smallish tue (3/4") but actually its working perfectly with the blower from glendale. Couldn't really be happy, at around 400 quid its a forkout but the guy sounds pretty nice running it and he's willing to service and keep it going for a long time from what I hear. So you may really want to think about it if your in looking for one. Small neat and powerful. ALl the best and thank you for your advice and time.

  2. Thanks Dale. You legend. Many tips that will be handy for a lifetime. Thank you. By the way while I'm at it if anyone reads this and has a xxxxxxx lower (in the UK) they are willing to part with .... Hopefully I will slowly get things going .... will let you know what my final solution was.
  3. thanks for all your help everyone.
  4. the only other thing I wanted to ask is about blowers. I take it they have a certain capacity to put out a certain amount of air at a certain pressure. Without getting too complicated and mathematical I take it different blowers have a different capacity to keep putting out pressure when say I cover the outlet hose of the blower. The two blowers that I have bought both seem to cut out completely and go into a kind of feedback when the outlet is covered, rather than say compared with a hose the water pressure keeps trying to push my hand away. Are there different kinds of blowers that act more like the water hose in my analogy? Are the older blowers more like that?
  5. John. Thank you for this advice. Good to know that 3/4" is big enough. The outlet of the blower is a rectangle of 5" by 6". It chokes down to a 3" pipe, which remains the same diameter until it gets to the back of the tue. Then obviously it tapers down internally as it travels through the tue. There are no jammed pieces of coke in the tue. I checked earlier today. When it is on it puts out a lot of air through 3" pipe, and then when hooked up to the tue it blows nicely out of the front. When I first rigged it all up I thought to myself that this should work nicely. Though it was a way from blowing coke off the forge like the forges I used at my teachers when I was learning. But it does not seem to be putting out much air with the air vent full open one I start to get my fire going. I'm presuming that its as when the wood I use to start the fire beds down and coke moves in front of the tue opening it stop the flow. I have had my poker in there to try and edge away any coke that it may be blocking it but my fire just keeps going out. This is of course with the airgate fully open. My teachers settup seems to be similar to yours. and the straight steel pipes that were acting as air ducts to 3 forges were about 3" I think. Thats why I'm surprised that its not working as the set up does not seem to dissimilar, and there would be the need to have the blower blowing straight into the back rather than being re-layed through 3" tubing. It's also why I thought the 3/4" tue outlet may be responsible. Its another good piece of advice to maybe play around or investigate the air uptake of the blower's side grills, as I take it the 1.50HP output is plenty. Do you think the 3 inch piping I got now and how its set up should be working? I'm in hereford. Thanks for you help. Hi Tom, 3/4" is adequate for your air outlet at the tue, large enough for most work, yet economical for fuel use. The airline setup you have would also be a problem as it appears to be choking down (and I am approximating guessing here) from a 4" diameter to a 2" and then back up to a 3" I should also check there are no jammed pieces of coke inside the tue, With that blower, and the airgate fully open, it should blow cold coke out of the front of the hearth. The only other problem area could be a restricted airflow through the sidegrills of the blower, the picture is not too clear on the grill arrangement, and the picture on the manufacturer/suppliers site just shows perforations, but these should be adequate , and a blower of this size should be capable of supplying four or more hearths at a time. Provided the delivey pipe from blower to forge is large enough to act as an air reservoir, we use standard grey plastic sewer pipe as main delivery from blower, then teed off to 2"/50mm diameter to supply to air gate on each hearth. Whereabouts are you located?
  6. Ok good. I'm clear about the principle. I will try and rig it up as you suggest. If it still does not work, then I take it my only option is to get a larger tue. Thanks for your advice. I really appreciate it. Tom
  7. Thank you! Just checking that I understand what you mean. Are you suggesting that I use as large a pipe as possible from the blower outlet to the back of the tue, and then let the front of the tue do the choking? got an air gate set up already so if I understand your just saying that the narrow tubing that I'm using may be the problem.
