New forge build

Recommended Posts

Just started making my forge today, I'll be taking my time while building it. Today I made my fire pot which is 11.5" x 8.5" and 3" deep. I always like looking at others builds so I will try to update this as I build it. Need to keep my eye open for a hand crank blower, otherwise I'll be making everything else myself. Going to be using coal from the local guild that I took my beginner Blacksmith class at.

That should be OK.

Make sure you devise a clinker breaker. Makes life easier. Don't go for slots.

You can cut a round hole in the base and have the clinker breaker shaft between the fire pot and the tuyere

Thanks for the suggestions for the clinker breaker. I was leaning towards one but that just solidified it. I was thinking along the same lines by cutting a round hole and then putting the handle right at the top of the tuyere. Just need to figure out what size to make the tuyere now.  Also need to figure what type of material to make the clinker breaker out of and how big to make it.

Found a Buffalo Forge hand crank blower on Craigslist the guy says it spins.  What do you think would be a fair price for it?  He's asking $150 and I'm planning to meet him after work tomorrow.

Without having it in hand, hard to tell about the price. If it spins without any bad noises or skipped teeth on the gears $150 isn't outrageous. Because it's missing the stand I would haggle with him about it $75 would be a lot better. Stands can be easy to fabricate.

Thanks Irondragon I was planning to try and get him lower on the price.  I didn't even realize it was missing the stand which is a good point.  Does anyone know what model this blower is?

I was thinking 98 was the year it was made as in 1898. It looks like a larger size blower. Looking at pictures of Buffalo blowers on the internet the smaller blowers have a fixed length for the crank handle. Where as this one has an adjustable handle length.

I don't recall any of them being date stamped; but I'm not an expert on them.  I do know that I have moved handles from one blower to another to suit myself...

Well I bought it for $120,it's heavy and spins pretty well. One thing I noticed is the fan blade has play in it because it was hitting the inside of the blower case. I split the case last night and the fan blade shaft has some play where it goes through to the gearbox. I took the handle off as well and pulled the gear case cover. Both sides had a lot of old pretty dried up grease, I'm going to work on cleaning it up and see about getting it apart. I have a couple screws as well as the fan blade stuck on the shaft. I will be using pb blaster and giving it time to do it's thing to work it's way in. One thing I did notice is both on the fan blade where it mounts to the shaft as well as a part in the gearbox they are both missing a set screw to hold them in place. I'll take some pictures as I have more time to work on it.

If the shaft runs directly in bore in the case without bushings, and they are oversized by wear, I’ve polished the shafts and used the smallest drill that would true the bore in the case. Used brass shim stock rolled into a bushing to fix it. Another one was really beat, I drilled it ou to tak a standard sized bronze bushing.

I got it all apart today and got all the old grease cleaned out. I think it was worked on before because 2 screws for the gears cover were hex head. Also on 2 of the shafts it looks like they used shim stock to take out any slop. Overall it appears to be in good shape and should go back together good. I also noticed one of the fan blades was closer to another fan blade so I bent it back slightly too make the spacing even, it might've been bent enough towards the outside that that was the noise of the blade hitting the case.

I've made some progress on my forge in the past couple of months, here's some pictures of the updated progress.

 

I was able to drill a 2-1/2" Diameter hole in the bottom of my firepot as well as the piece of plate of my tuyere that will bolt to the bottom of the firepot.  I also drilled and tapped 4 holes in the bottom of my firepot for the tuyere to be bolted up from the bottom.  There's also a picture of my tuyere welded up, you will see there's a slot I ground in the tuyere mounting plate.  I'm going to run a piece of 1/4" round through there for my clinker breaker handle.  My clinker breaker will be one of the hole slugs that I drilled out and ground down for approximately 1/4" gap around the outside of the clinker breaker to the edge of the hole in the bottom of my firepot.  I need to make brackets and fab the ash dump at the bottom of the tuyere next time I work on it.

what type of coal r u planning on using?  

I just checked your profile out. Are you talking Kens custom?  I'm there in February!  

I'm planning on using coal from the local guild, they have a pile at the school of horseshoeing that I took my intro to Blacksmithing Class at.  I looked at Ken's Custom for classes but they were filled up and I wanted to start learning right away.  Maybe in the future I'll head up to a class up there.
