Spindle Adapter Fitting
Once the bench grinder side guards and the grinding wheels have been removed (please note that the lefthand grinder shaft has a lefthand threaded nut), the spindle adapters are then slid over the grinder shafts. There is a right hand and a lefthand spindle adapter in the kit. Please remove the grub screws in the adapters first and then fit the adapters as far as they will go onto the shaft. Once fitted, reinsert the grub screws (one in each adapter) and tighten them using the allen key.

Please wipe a thin layer of oil all over the Bench Grinder’s two Spindles / Shafts before sliding the Spindle Adapters over them. This will help prevent rust from building up on the spindles, which if it does may result in the machine’s spindles ‘rust welding’ themselves to the spindle adapters, making them difficult to remove. ** If any spindle adapter is too tight to slide over the bench grinder spindle / shaft, this is because the bench grinder’s shaft is mass produced (not precision machined) and may be a bit ‘rough’. With the motor running, please use a flat file / abrasive paper etc and clean the shaft up. This will then allow the spindle adapter to slide over it

Scratched Items - If there are scratches in the item being polished a series of wet and dry abrasive paper / discs etc may have to be used first to remove the scratches prior to the polishing phases. As gold is very soft, extreme care must be taken. Do not use abrasives on chrome plated items.

Safety - Safety Goggles / Glasses, Gloves and Dust Masks (not supplied) must be used when using machinery.
Always polish in a position with the polishing wheels etc spinning away from you and not towards you.
