I’m building a belt grinder but I am deciding to use a 1phase motor with a vfd but someone has said to me that you need a 3phase motor to use a vfd but when I looked on eBay it said I can wire it to for a 1phase input and output. This is probably a stupid question but is it possible to run a vfd with a one phase motor if wired correctly. I want to use a 1phase motor because I am using household electrics. 

Frosty, I wish I could take a class or speak to a blacksmith but there is none in my area they are all either too far away or too expensive. I was just thinking of building a burner to test if it would work then build a body out of refractory. thanks for the advice.

I would need it for basic forging I wouldn’t want one to large or to small, I just need to build a burner because I have fire bricks already from my old coal forge. So I just need to figure out a design which I’m not good at because I haven’t made any before. If you have any designs would you be able to share them with me

In the UK, you'll probably be best served with a single-port burner based on an Amal atmospheric injector. They have very good turndown and tend to be reasonably quiet when run at at low pressures, even with a single port burner. When run at high pressures, they are loud, but this is true of nearly every burner design I have encountered.

Given  your preferences you should definitely go with a ribbon burner, however one does not preclude the other.  There are a couple threads on here regarding naturally aspirated ribbon burners (NARBs) which give details about how to make them.  If you wish to go with a blown ribbon burner, Wayne Coe has plans on his website for that.

I have looked up ribbon burners and I find them a bit complicated to get my head around in text form (instructions) is there anyone that has got designs of a ribbon burner that is simple and easy to understand. I also forgot to add it has to be cheap.

I am planning on making a propane forge and I am just wonder what burner should I build I thinking of a Venturi or a ribbon burner, it needs to be a. quiet b. Efficient. Ps if you have any plans or ways to make the burners they would be much obliged. Thank you

Thank you this has helped me alot

Thank you for the idea

I am in the process of getting some tubing for it to flow better so I could re do it

I have a stick welder 2 angle grinders (one 4 1/2, one 9 inch) I just don’t have thick steel tubing to weld with because the thin tubing I have now will just melt

Okay, how can I make the design more efficient because that’s all I have.

A couple issues I can see. 1 your air inlet pipe is restricting as is, and will collect ash blocking it further. ( a T pipe will be way better for a bottom blast coal forge. Think of the T on its side the long part is your air inlet then one part goes up to your forge pot and the other is capped or better, put a weighted flap cap on it to collect and dump ash. ) 

2 the box on the fan is sort of a good idea but it doesn't efficiently direct the air to the pipe so you are barely even getting what the fan can produce.

Can you give details of the fan you'e made Alex, there may be away to improve it, also your supply to the tuyere as Glenn refers to may be restricting flow if you're now working at a lower pressure. Is it aside or bottom draft forge and what fuel are you using? Pictures are always useful if you can supply some.

 

 

I am using a bottom draft forge and using coal

I’ve recently made a forge blower out of a fan it doesn’t give off high pressure but gives constant air to my forge. It takes longer to heat up stock but is quieter than my other blower by a long shot. I’m just wondering if it’s enough and if not what I can do to improve it, if you have a suggestions. 

That’s gave me a good idea thank you

Hand crank blowers can be quite quiet, electrically powered ones can be very annoying!

I have been looking for a hand crank blower for a while and I can't find them in the uk. 

The smoke is not noticeable from what I've seen because I don't really put green coal straight on the fire I put it around it to make minimum smoke as can

I use coal and my blower is a electric air bed pump and my anvil is a homemade railroad track double horned anvil and its nailed down to a railway sleeper rapped in chain 

Im not doing it for long really its around 2 1/2 hours a day for only around 4 days a week. I have dampened my anvils ring as much as i can but theyre still annoyed but also my forge blower is quite loud aswell. Im in the west midlands

Hi Steve, thank you

I live in the uk, I am a beginner blacksmith with a back garden forge and I do make a bit of noise on accident most of my neighbors don't mind the noise but one neighbor has been threatening to report me for noise complaint. What can I do to make my forge and anvil quieter.
