Erbauer Jigsaw (Royston SG8)

Basic jigsaw, used but works. However, full honesty - it has driven me mad. I find it very hard to cut an accurate straight line, the blade always want to veer right. Its been reduced to only used for rough cuts where the cut won't be seen or is finished with another tool. I may have missed some fine adjust in its footplate or the blade holder or something, but its finally reached the point of 'if you can make it work for you, have it'.
