Hi
I'm currently working on a craft project which involves removing a slice from a lignum vitae wooden lawn bowls ball. It already has a small bevelled detail around the ball which i'd like the cut to follow about 1 inch up the bowl. I'm totally new to all things woodwork and tools used so if anyone has any advice on how best to cut this section and what i'd need to do it it would be more than appreciated.
Regards
Ady
I can't tell you how to make the cut.
I can tell you a way to make a good mark to follow, using a scribing gauge. I've posted on their utility before, so here's the link so save repetition:

I've even tried to encourage others to try it:

In your case, you need a way to make a bowling ball sit still - I suggest a pastry cutter, or a coffee jar lid, or a cereal bowl.
Sit the ball in your stand, with the stand on a flat surface - a workbench or kitchen counter top should be "flat enough".
Now adjust the bowling ball so the bevelled detail is perfectly parallel to the work surface; this can be checked by setting the surface gauge to the heigh of the detail, and moving the surface gauge around the ball. The relationship of the point to the detail should remain constant. Tweak until this is the case.
Most of the the work is now done.
Now adjust the height of the surface gauge point to be 1 inch lower than the detail, and move the gauge around the ball, scribing your mark.
Job done.
It is important to note, that whilst "universal surface gauges" are elaborate and quite pricy, all that is needed is a adjustable height point on a support, which can be easily improvised with scrap wood, screws, clamps etc...
