    Thanks for the input Dan. I really appreciate it. I have provided a .5" vent hole it the top of the kiln and will be adding a smaller hole or two in the bottom. I had thought the door would not fit tight and provide a way for air to get in. But as luck will have it the door fits snugly and the...

    It is very well supported by the silicon and the bricks have a deep slot cut into them where they touch the cast refractory. Allowing some of the cast refractory to engage the bricks. You will be able to see this detail when I cast the top. I should have taken more photos when I mounted the...

    I have already made a S.S. drip pan to catch any dripping wax. I will be doing mostly lost 3D resin. It doesn't melt, it turns to a gas and gets vented out. The small amount of wax used for the spur is not worth recovering. Mark T

    I started with the kiln floor, casting the horse shoe collar around the two soft bricks that will be the bottom of the kiln's interior. The corners are reinforced with piano wire as I expect to see cracking here. And I cut a notch into the soft bricks to stretch some piano wire across the bricks...

    Everything except the steel I bought on Amazon. And yes the bricks are not cheap, it is what it is. They are of excellent quality. https://www.amazon.com/dp/B081K26JZM?psc=1&ref=ppx_yo2_dt_b_product_details Mark T

    I am using 13 soft fire bricks 2” x 4.5” x 9” in all areas facing the ovens interior. And I will be using some castable refractory cement to make custom shaped boarders that will secure the bricks in place. No grout or other binders are being used as I expect those joints would probably crack...

    Online metals in Seattle. I am up that way fairly often and I pick it up there rather than having it shipped. They stock almost everything but shipping is a budget buster. Mark T

    Yes Richard, about 15 inches accumulated so far and more coming today. Snow plow stops about two miles from my driveway so have stayed home the last week. Woodstove keeping the shop cozy but UPS stopped delivering materials for some reason. Warm air and rain coming on Sunday. To be honest, I...

    Thanks Tug40, I like to be tidy. But my shop doesn't reflect that.

    It is now time to make the element. I need to make it now so I will know how big to make the cuts in the bricks where the element will sit. I am using 18 gauge Kanthel resistance wire to make my element from. Here is everything you need to know about this wire. Kanthal Wire Specifications: I...

    I am setting up a bench-top foundry in my shop for doing lost “resin/pla/wax” casting and I need a small kiln. I looked at commercially available units and found the prices quite sobering and then the shipping costs and for me (10.3 percent) sales tax. So I looked at home built units on...

    Hello to you all

    If your compressor is in a business environment a state inspector will show up one day and do some ultra sound tests and then condemn your tank. They always find a thin spot. My boat shop had its tank condemned 7 times in twenty years. The first time I was working down in a bilge when the air...

    Casting your own steam engine castings?

    You have made some very good points. My drawing was from a time when I had no experience in building a furnace. I never needed the hole in the bottom. I never used a steel crucible but did buy several graphite crucibles. I did as you suggest making a plinth the diameter of my crucible. The...
