Nice idea! That's something I will look into. The forge frame is probably made from iron/steel. It's very old, so I'm not sure if it's steel or iron. The table/plate is sheet metal. DennisCA, in Norway you will find many different designs/versions of the 'feltesse'. When I bought mine it had the holes drilled for mounting the blower. Earlier today I checked/confirmed that I can move the firepot so it all lines up correctly.

You say it is best to have the firepot centered, would it work if I made an extension to the left, making it centered? I could try to make a simple table with two legs on the other end, and use some kind of hooks to attach it to the main forge table? Then I could build up the green coal in equal amounts on the sides.

The firepot is rectangular. The top picture is a bucket. I'm standing with my back towards the camera while forging and pump with my right foot. I kinda thought the placement of the firepot wasn't the ideal, but since the drive wheel need to line up with the axle on the forgeblower, it has to be placed like that. My firpot is 235 mm long, 205 mm wide and 40 mm deep. That's about 9 x 8 x 1 ½ inch. I've been thinking/worrying that the depth may be too shallow (even though that shouldn't interfere with the forge getting hot?)

I don't have a picture here right now, but can post one next time I use the forge (probably this weekend). I do have some picture of it during restoration, and I haven't changed much since. If you want to see the airflow though, I will need to take some new pictures. I know forges need more air *volume* than air *pressure*, and since I need to treadle quite fast I'm unsure which one of them I get the most of.

I'm living in Eastern Norway, so finding 'professional' blacksmiths are rare. I am not totally sure if I'm burning the coal to coke. I usually have a decent amount green coal 'huddled' around my firepot, in an attempt to transform the coal to coke without too much smoke. Usually I end up with having to use some green coal, since the coal/coke in the firepot seems to burn quicker than i can 'produce' coke around the fire/firepot. SInce the forge is foot driven, I need to treadle quite fast to get enough airflow going. The coal I'm using are from somewhere in Germany, and it doesn't really produce much clinker. I don't have any specs on my forge, since it is from a unknown producer way back in the (mid) 20th century. But if you've seen Make'n Create on youtube, I have a very similar 'feltesse'. They were used out in the field doing forging under construction, restoration etc. How small can the coke pieces become before they steal more heat than they produce? There is no need to quote the entire post that we all just read, and when quoting its polite to trim the post to what is needed many members still use dial up and pay by Kb used

I use a oooold coal forge which is supplied with air from a foot driven blower. I think I might have a problem with the coal I use. The coal burns pretty quickly, and goes from pieces around 30x30 mm to 5x10 mm. So within 45 min of the start of forge session I need to clean out the small pieces, since it seems like they dont burn. Are this the case, and I need to treat them as ash. Or is it just not enough air to heat the coal?
