Moderator Timing Shims
Moderator Timing Shims
Time your moderator to your preferred rotational orientation with these precision shims.
The stainless steel versions includes a 0.1mm, 0.2mm, 0.3mm and 0.5mm shim that can be combined to adjust the spacing in 0.1mm increments and are available in 1/2-20UNF (13mm), 14mm, 18mm and 20mm.
Each biaxially oriented polyethylene terephthalate (Mylar) shim is 0.23mm thick, or good for about 1/5th of a rotation on a 1/2x20UNF thread. Different ID/OD specifications are available to accommodate different threads and shroud diameters as well as custom sizes. These shims are non-marring.
