I’m all for making a trip down to Haysville to do some recon. If anyone wants to meet up at their shop with me I’ll be aiming for around 7p tomorrow.
To further educate the board so they can go to the insurer with numbers:
Working temps for most metals is around 1000-2500 degrees. Propane burns at 2400. Solid fuels, specifically coal and lump charcoal, can burn from 300 to 3500 depending on air flow. Ambient temperature around the forge will depend on forge construction and refractory material.
Lee had an idea for a fire brick and angle iron forge that I would like to see before any finalization of any design. Since I think this may have got lost in the weeds of the social hour the forge construction can be built to accommodate restrictions easily if I know which ones are imposed on the space.
Based on IFC 2012 (adopted by the CoW) and IFC 2018 (adopted by Sedgwick County) we do not require an operational permit for single LP tanks or combined tank systems under combined water-gallon size of 125 gallons unless the space has been specially told that it is disallowed due to special operation restrictions.
Noise ordinance in the city limits places the cap at commercial zone at 60db between 8a to 10p, and 55 db between 10p to 8a. Subtract 5 from both values if the space is special permit residential. For reference 50db is equivalent to standing near your fridge while its running. Propane forge burner db is around 100 to 140 near the forge. A hammer blow on an anvil can be just as loud near the anvil. Db will decrease by a complicated math problem here amount with distance from source.
@rustin.atkeisson I’m going to grab the bench belt sander and we’ll see what we can do with it.
ADDED: After some digging around in fat code books any forge we make would be classified as a Class B or D Furnace. From my mind numbing troll through IFC 2012 and 2018 unless special excluded or permitted because of special zoning for the space both are treated like a household oven or bbq grille (depending on location) as long as we are not trying to work flammable material or chemicals in the furnace/forge. There is also a minimum safe distance from different building material based on temp but honestly I started dozing off. It looked like 3-5ft was a recurring theme for four digit temps.
That may put a damper on our thinking of making our own charcoal from woodshop scrap.
Incase anyone needs a sleep aid/ lite reading.
