AJS/MAtchless single engine timing disc and support

thingiverse

Combines a support for timing disc and a bracket to hold a pointer on the engine. This will aid in setting ignition timing and also valve timing on all later single engines with alternator.. Included are pdf and svg files to print the timing disc for 1964-66 short stroke single onto card . A template is included in the file for marking any timing degree. The bracket supports a slider holding a pointer. The slider is mounted on an 8mm screw and this allows micro adjustment of the position of the pointer needle. There are 2.8 mm holes in the disc support which will allow insertion of 3mm screws to hold the card disc but in practice this has been found unnecessary. The photograph shows the bracket and disc in place on the left of the engine, . The pointer bracket is screwed into the inner primary timing case and the disc is held by the disc support on the end of the rotor. Hope you find it useful.
