John Vojtech and the people at UMM-USA (Unique Master Models) have come up with yet another tool that is well worth having in your collection. The Profiler Scribing and Contour Guide is a very versatile tool to help you with scribing and replicating inside and outside contours of your models.

Modelers may need to find the exterior or interior contours of parts to either scratch-build additional parts or shape/sand kit pieces to fit better. The guide is made from a thin piece of pliable metal and covered with a non-slip material. The metal can be bent in several contour position without breaking it and once bent has no memory. The guide also is sold with a blue straw like holder with plugs at either end, so it is easy to find when you want to use it.

The guide can be bent and placed on a model lined up with areas to be scribed and taped down so it does not move, then a scriber can be used along the guide.

Another beautifully crafted tool from our friends at UMM-USA is this new punch and die set, accompanying the numerous other tools used to punch standard shapes out of thin brass or aluminum, or plastic sheet stock up to 0.080 (2mm) thick. In the set you’ll find an aluminum die block with hole sizes ranging from 0.6 mm (0.024”) up to 3.0mm (0.12”) diameter, accompanied by the hardened tool steel punches of corresponding size.

If, like me, you’ve tried slicing round stock to make buttons, access covers, hatches and the like, and never managed to get parallel surfaces, you’ll welcome this fine tool. It’s great for adding subtle detail, for creating instrument glass, access panels, fastener heads, and the like.

Our thanks go out again to UMM-USA and John Vojtech for his generous support to the review team here.

This is volume four in the Single series. This is a thin book with no text other than photo captions. The book contains very nice 1/72 and 1/48 scale drawings, B&W photos of various details and pages from the manuals showing different systems. There are also three-color photos of cockpit details.

One page that should prove extremely useful to the model builder is the diagram on page 20. Showing which wing areas were natural metal which areas had two coats of filler those with one coat of filler and then sprayed with silver paint and the areas of silver paint only. There is also a beautiful rendition of the instrument panel and an index to its layout. The book concludes with three pages of color drawings of P-51D 44-14292 “Man O War”.
