Trammels or a beam compass set are fairly straight forward tools used to mark out a circle or arc. In order to strike the curve they have to be used with a length of timber onto which the two tramels are mounted. The radius is then set by a process of trial and error which is irksome in itself; however with the new UJK Technology Trammel Heads a 64cm aluminium bar (with metric scale) is supplied as part of the kit and an optional bar of the same length can be joined on, giving a total length of 128cm.
Standard trammels contain a pair of steel points, as do the UJK Technology set, but in addition a rather natty arrangement is included whereby a ‘V’ shaped cutting blade can be inserted instead of a point. This means that the UJK Technology trammels can be used to cut precise arcs or circles in paper and card, but the good news doesn’t stop there. There’s also a rather smart Axminster pencil as well enabling an arc to be drawn instead of being cut or scribed.
The trammel heads are made from black anodised aluminium and use solid brass screws; the bars are extruded aluminium finished in the now familiar UJK Technology orange colour.
Whatever your circumstances, if you need to make or cut accurate curves and circles, the new, versatile 3-in-1 UJK Technology Trammel Set should be a serious contender.
