We just used a hammer and a thin-strong-something to knock out pins in and out accordingly. Naturally, that got boring quite quickly, and eventually we bought something similar to this: http://www.ebay.co.uk/itm/TK012-6mm-...item53f9ff7fb5

Better than the hammer and pliers approach... but not by a lot, haha. It'll do the job but is still mighty fiddly.
