Solder vs epoxy should be a similar amount. You flux up the block and tin it with solder (ie. apply a coating of solder to the part to be joined). Then flux up the lid place on heat both apply a bit of pressure and once hot they're drop together, the solder joint is made and very solid. You need enough heat to melt the solder and to have bother parts cleaned and fluxed up or it won't work. I use a butane torch - gets plenty of heat.
