I've been using Rotary Craft on my server and if you want to go nuts with ingots, I'd suggest you do the following.
You're going to need the following: an extractor from RC, aqueous accumulator/pump of your choice, liquid pipes from RC, bevel gears from RC, 2 cvts from RC, 3 shaft junctions from RC, 4 magnetostatic engines from RC, Redstone conduits and energy from TE3, 62 belts from RC, 2 repeaters, 2 Redstone, a Redstone clock from Expanded Redstone, (recommended) dynometer (forget how to spell it) from RC, and an inventory management system of your choice (preferably AE and impulse itemducts).
Unfortunately this is pretty late game as you need bedrock shafts to make cvts, in current Monster 1.1.1, you can use one magnetostatic engine and a worm gear (RC) to power a bedrock breaker. But oh is it worth it.
I will probably make a drive document for this or something and will upload screenshots for my setup. If you don't know anything about rotary craft I suggest actually reading the manual and watching tutorials. RC is a pretty awesome mod.
Set up engines next to each other with the shaft junctions merging all the power into the first cvt. Fill all belt slots. Use Redstone control. Set one button (Redstone signal on or off) for 32x speed and the other for 4x speed. Outputting from the first cvt place the second cvt and set the same button as the last 32x speed, to 32x speed (ex: if the first cvt had 32x speed when Redstone signal is on, do the same with the second one) and same with the 4x speed. Next place repeaters going towards cvts, Redstone behind repeaters, and Redstone clock behind Redstone. I'd set the clock to either 1 second or 2.5 seconds. Outputting from the second cvt should be dynometer which outputs to bevel gears which outputs to extractor. Set all engines to max output.
If you provide power to the engines, the dynometer should be alternating every one or 2.5 seconds. The torque should never exceed 512 nm, and never be below 8 nm. The speed should either be 32 krad/s or 2 mrad/s. Your extractor should process at least a stack in 10 seconds. Likely less.
Again I'm working on publishing this to a Google doc but if you understand it, knock yourself out.
