How do I scribe a taper?

(1/2) > >>

DarrenUK:
Can anyone suggest a tool or a quick easy way that I can use to scribe a straight line down the centre length of a tapered bar?

I know I could measure and mark each end at the centre then just use a straight edge to scribe but would like to find a quicker alternative method.

Red line on image below is where I want to scribe.

Pete.:
Mount it between centres on a lathe and use a height gauge scriber along the top of a piece of bar held in a toolpost at centre height.

I like that idea Pete!  :thumbup:

Forgot to mention, I have no lathe, just a small SX2 milling machine and a few basic tools.

angus:
how accurate does it need to be ???

use some marking out blue

dirty way put in a vice holding the ends, the holding a spirit level, and looking at the bubble drag it along the top edge

will be fairly close, but maybe not close enough for what you want ?
