| What is this gizmo on my planer for? |

| awemawson:
I've been using my Dominion Supreme Eliot combination woodworking machine quite a bit recently (making a vast linen store / airing cupboard for support of our letting holiday cottages) and using the planer I realised I don't have a clear understanding what a bit of the planer fence is intended for. It slides in a vertical slot in the planer fence and is locked by a wing nut. I'd assumed it was to give more stability to the fence - maybe to stop vibration - but I've a feeling that there must be more to it than that. Virtually every 'professional' (ie heavy cast iron) planer that I see pictures of on the web has a very similar arrangement. ... so what am I missing ? What's it for ? |

Hi there, Andrew, I think it has two functions, first to (help) hold the work-piece flat to the table and, second, to do that in a way that facilitates forward movement but opposes kick-back. The modern equivalent, I think, is a plastic gizmo with parallel flat leaves, all slanting in the appropriate direction. The term 'feather-board' comes to mind. They are also recommended for use on router tables. A browse on the Axminster site might show you some pix of the thing I've tried to describe. I'd try to find you a pic and add it to this post but I'm eager to go and machine a back-plate for my recently acquired (pre-enjoyed) 4" Grip-Tru lathe chuck. Please excuse me. |

No Pete I don't think so - I'm familiar with anti kick back devices. This gizmo stays in the plane of the fence and the timber slides past it - the only thing it's touching is the 'outfeed' table, which is height adjustable, so I assume (dangerous) this is why the gizmo slides vertically. |

Hi there, again, Andrew, Chuck back-plate job got delayed by real-world factors!! :bang: :bang: :bang: So here I am again. My mistake about finger/feather boards and anti kick-back - I wasn't looking closely enough at your photos. |
