Recommendations for circle scribers for primary hull grid lines?

[nitflegal]

I'm looking at rescribing the various "panel" lines on my PL Excelsior and Enterprise refit to give something a wee bit finer than the ones on the kit. I've used an Olfa compass cutter in the past but one could hope that there is something a little more precise available these days! Any suggestions would be most welcome!

To be honest, you can't get much better than a really good quality pair of drafting (draughting) compasses. The best ones will accommodate a blade where the pencil lead normally goes. You may even want to look out for an old, second-hand precision set - the ones I have are over 30 years old and probably better than most new ones.

I've never found the dedicated compass cutters like Olfa to be of much use.

I have a set of compasses and calipers that are part of my father's architect set that I used to scribe lines in precise dimensions. Probably your best option is to use a set of plastic circles as a guide to scribing lines.

A good compass fit with a scribing pointed tool.,or maybe the "yard stick" compass parts.A standard compass will only give you so big a circle.

True, but the same companies that make good compasses also make beam compasses with he same fittings Some of these can draw/scribe circles up to 18 inch diameter.

They are not cheap but will last decades.

Amazon has a fair selection of Beam Compasses which are not too expensive-

They also have a beam-type circle cutter which may work for 1:1000 saucers-
