When I spiked rail to a sleeper I found the spikes I had were too long. I decided to change the sleeper size to 12X12mm to accept the spikes.
Also I found spiking on hardwood was very hard and need pilot holes for spikes. So I decided to change the sleeper material to red cider that supposed to be strong against water and soft enough to spike without pilot holes. Applying furniture oil was also cumbersome and I decided not to apply it to the sleepers.
ところがレールをスパイクしたところ、とんでもないことが発覚。スパイクが長すぎる(約12mm)!困ったな。しかも堅木だと下穴を開けないとスパイクが打ち込めない。非常に面倒。しょうがないので枕木を12X12mmのRed Cedarに変更することにしました。杉は水につよいのでいいかもしれません。塗装も面倒なので、省略することにします。クラブレールとのつなぎ方は後で考えます。
