So im playing on a tekkit server and i am going to make a company that macerates/smelts stuff for the player. I have everything figured out but I have one problem, theft.
Before I go on heres what i have planned. The player will put all his ores into a chest and then put an item in another chest, say 32 gold, the 32 gold gets taken out of the chest which triggers the machine that sucks all the ores out of the chest and macerates them. After they get macerated they move on into the furnaces and get smelted turned into ingots, I'm sure all of you have something that automates macerating/smelting. However my problem is, that macerating/smelting takes time and I dont want my customer to have to wait in my shop for minutes depending on how much ore he wants turned into ingots. I want my company to be able to work while I am offline and am having trouble thinking of a secure way to do this, suggestions please.
