Both of these mechanisms mount to the fence and provide pressure drawing the wood toward the fence and downward. These are apparently very useful on both lumber and sheet stock. Apparently they are very helpful holding thinner sheet goods against the fence.
A previous thread talked about holddown devices in general: What are the Best Pushblocks/Hold Downs . In this thread I’m trying to focus on these two fence mounted devices.
The Board Buddies (also sold as Board Mates and “Yellow One-Direction Anti-Kickback Safety Rollers”) are either screwed into the top of an auxiliary fence or into blocks that in turn mount in a T-track. Peachtree sells a UHMW (ultra high molecular weight) polyethylene to mount it to but I believe most just use a piece of wood.
Sold in sets of two rollers, the rollers can be mounted to either side of the blade or behind the blade. The blocks slide back and forth in their mount and the roller screws up and down in its mount. Either way, the rollers are a bit bulky limiting their use on smaller pieces.
Their unique feature is that the rollers rotate in only one direction allowing it to function as an anti-kickback device.
Grip-Tite magnetic holddowns are the primary product of Mesa Vista Designs. Some versions come with their rollers attached to the bottom. The rollers are available separately and with a plexiglass mounting plate. This plate can mount either to a T-track on the face of the fence, screw into the fence, or presumably be clamped to the fence. Two holddowns are sold with the plexi-glass as the Kickback 2. There used to be a Kickback with one roller, but it appears to be no longer available.
Instead of a rubber roller, the rollers use a 120 grit sandpaper to hold the workpiece. The mounting is much easier than the board buddies and the they appear to hold closer to the fence, although I can’t verify that.
The name implies an anti-kickback capability, but I’m not sure how that is implemented.
Smaller and lighter, the rollers seem more convenient to use than the Board Buddies. Both are in the $48-$56 range, effectively the same price.
Which is the better choice? Which worked or didn’t work for you?
