Another noob question- delicate/thin part removal from mold

Well it is inspiring to know that others have also started at the beginning and muddled their way to success.
I think the moral of the final pic is to invest in investment.

 

Will a toaster oven really work for burnout?

 

Figure most toaster ovens will probably hit 450degrees. Now imagine letting that thing run for 24hrs! Here's a good idea, do it in the driveway or on the patio.
I don't trust anything I can buy for 8bucks at an Amazon resell store.

 

The wife didn't get one of those...

There is also the flower pot method that I have used a few times but that was before i made the temp controlled electric furnace for about $140

I found a reference to this method somewhere and I wish I could credit them but I forgot where I saw this.

You need a flower pot (preferably dry or slowly dry one) that fits over the burner section of the coils, not on them or over the sides. They say wrap aluminum foil around the pot to keep it from cracking.

The flask for the trigger guard should fit within the pot so place the flask on the coil but on something to raise it above the coils.
Place the pot with foil over the flask and let her rip.

There is a lot of truth to that statement... and flask size does matter when considering your time/temp. Also are you steaming out the wax or will removing the wax be part of the burn out cycle.

Most all if not all commercial jewelry, dental and general purpose investment require temperatures above 1300° F
This should explain it.... https://www.ganoksin.com/article/wax-casting-burnout-cycles/

I believe I read that you now have a better way to read/take temperatures so I would give this a shot very cheap and it cant hurt... LOL

Here is an old coil burner that is preferred for this method


This is not....but it's what I used and it worked fairly well...

(This isn't the one I used. Mine had tighter coils but was the same style)



Edit: I forgot to mention I have also done the high temp part of the cycle in a propane furnace.

Put the flask in a clay graphite crucible inside the furnace cover it with cast iron and keep your eye on it. You will need to learn the color of different temperatures. IE: 900°-1400° F Plenty of refence on goggle...
Turn the furnace on and off as needed to maintain 1350° as best you can. I have done this three times and though each time there was a different challenge the castings came out okay.
