AMBU PRODUCTION POST STRAP MOULD
For the large shop or manufacturer, the AMBU-Washburn Post Strap Mould, is made with the special indexing feature of Figure [11]. This is easily adjustable and will cast straps of both odd and even numbers of teeth for 7 to 19 plate groups. Otherwise its construction and appearance is the same as Figure [10].
Both of these moulds are made for real use and will turn out three perfect castings per minute. This unusual speed can be maintained because the castings are easily removed. In Figure [10], the upper part of the mould is resting on a part of the handle made for that purpose and a slight blow on a hardwood stick, on the top of the post, will drop the casting instantly.
