I made a rail bender as left based on the article found in the web site “JJ & C RailRoad ”. However the site seems closed and could not be found any more. In original design a drill press vice is used as the base of the bender. However drill press vices are not so cheep in Australia. So I made up the sliding base from hard wood. The wooden base works quite well. The base is made of 19X40mm hardwood and assembled by wood-screws.
レールベンダーを自作しました。JJ & C RailRoadというサイトで作りかを見つけ、それを元にしてあります。このサイトは閉まってしまったようです。元の設計ではマシンバイスをベースにつかうということでしたが結構高いので、ベースも19X40mmの堅木で自作しました。
I made 4mm wide grooves in side rails and sliding block by router and fix 4mm thick hardwood plate to the sliding block. This allows the sliding block moves back and forward in the side rails. Adjust groove width or thickness of 4mm hardwood plate to obtain smooth movement.
