Looking at the pictures, it sees to me that it might be less easy to set accurately than a conventional scribing block.

It appears to be aimed at the building trade, where the level of accuracy is lower than that which we as engineers would require.

Seems unlikely that I shall be either buying, or making one.

I had that one come up a few weeks ago and did not think it offered anything that my compass does for scribing (carpentry etc)

Odd legs and be use for any of what they show in the video either by running the notch along an edge of the back of the notch against a vertical surface. Dividers will do circles. Both are also a lot less bulky. In both cases Substitute compass with a sharpie if you want to mark rather than scribe.

On the gadget you could substitute a scriber for the pencil and it would be ok for sheet metal work if you do that sort of engineering

A gimmick looking for some suckers? I didn't get to see a price.

I think these sort of things are invented by er sort of inventors, picked up by some marketing suit with no practical experience and added to the portfolio. Then they get bought by wives and other relatives looking for a present that fills the right price bracket to look appropriate.

The blurb does say "woodworking" and show it posed on Sterling-board, which is hardly top-rate cabinet-making material; but it could be adapted for closer to our engineering needs.

I doubt it would confer any great advantage over what we already use though..

Where did you £8?

If anyone is interested, there is a genuine Saker tool and numerous imitations, the main difference being that the genuine one is aluminium and the copies are plastic (and hence approx. 50% of the genuine price).

I bought the copy one and it is not good at all. It would be improved by being made out of rigid aluminium, but the hinging and clamping mechanisms are very poor. The deep hole pencil that came with it is good but the rest is only fit for the ideas box.

As a concept it is good, but the enginering details are lacking. One day, I will draw it up on the computer and make another that works properly.

Trend sell a better version, which has positive screw adjustment of the scribe width. Another one worth copying for your own use is this: http://www.tooleypark.com
