Runner & Riser Pins

Description

Handmade Hardwood Runner and Riser Pins

Hardwood pins are set a distance from the pattern to allow sufficient space to cut gates into the mould. The pattern and pins are coated with parting powder prior to covering with sand and ramming the mould firm. The pattern and risers are rapped prior to removal.

It is important that the sand is not layered by compacting into separate layers with the butt of the Rammer. If so these sand layers can separate causing the sand in the mould to fall out.

High quality Hardwood pins are always made from hardwood with a coating of linseed oil to prevent water absorption. They come  in various length and diameters to suit the size of the casting, feeding requirements and moulding box size. They have a draught/taper which allows easy removal from the mould. 

Some founders prefer  to use a runner & riser cutter and cut the runner and riser after the mould is rammed up

Supplied as a Pair

Sizes are shown in inches from smallest end of the taper  and are 6 1/2” in length.
