Hi Delboy
I've got two pin pushers, the second one I think is by the modelling company Amati which I bought from our local model shop a few years ago, it does the job as long as the wood is fairly soft, the only drawback is the relative thinness of the barrel which takes the pins, I found that some of my pins with slightly bigger heads wouldn't drop down the barrel.
The other one I've had for much longer and is a standard panel pin pusher available from any DIY store, it is much bigger and consequently far stronger taking pins all the way up to panel pins designed for nailing hardboard, it will also take the little brass pins but with less accuracy in placing them.
The other method I often use is to hold the pins about half way down the shaft in a small pair of long nosed pliers (like the ones used for electronics) and then gently tap them in with a suitable small hammer holding the pin in position with the pliers until the pin is far enough in (just before the head traps the pliers underneath it)
Hope this gives you some idea
Happy hunting
Robin
