Out of Business...Forge Help!

[tippit]

My son came home for a visit and is interested in blacksmithing now...so I sent him back to Crested Butte with some of my stuff including my old one burner venturi forge.  Now either I gotta make one or pick up one of Darren Ellis's forges.

Question:  What is your take on venturi vs forced air gas forges?  Thanks...Doc

Well, to be 100% honest I don't have a huge aount of experience with venturi burners. All I will say is that I was disappointed enough in mine to put a blower on the back. I just couldn't seem to get the mixture right & get it hot enough without. It was giving me 2 hot spots & varied temperature gradients throughout it's length. I rigged a hairdryer onto the back of the thing (OOOOOOH!!! Look how hi-tech I am!  :D  ) & turned my gas reg. all the way up. Working back from there, with the 'blower' on LOW, I found that I could get a much more even heat.

Steve, Don't worry I have a bunch of knives made up just waiting handles

Vertical forge, forced air.
You need any help, I'll send you pictures.
There is no need to buy one. Just make it and you'll not only learn a LOT about how/why they work, but you'll be far more able to tweak them as necessary.
Rob, where have you been!!??!!

Is there any advantages to the vertical versus horizontal? Obviously vertical must be better if thats what is most commonly seen but why?

I have a horizontal two burner with venturi burners from Zoeller Forge.  They work great and I have no problem getting up to forge welding heats with 2 inches of wool and 1/4 inch of satantite to seal the wool.

I agree that making your own is a great idea and will give you a much better understanding of how they work and what it takes to tune the burner system you create.

unless you are making steel there is no need for a forced air burner.  Ive forged out of a 3 burner venturi for over 10 years, made hundreds of knives, mostly big knives out of thick stock, no problems.
