BAC-MAKER, is one who makes liquor-bacs, under-bacs, coolers, mash-tuns, working-tuns, &c. for the brewers. The workmanship is partly carpentry, in a particular manner, for it must be tight enough to hold liquor; and partly cooperage, viz. the mash-tun, or vat, which is hooped. There are not many of this trade; and it requires chiefly strength, with a little art. A small stock of stuff, besides tools, will set a man up tolerably well; but with 200l. or 300l. he will make a good figure in business.
