I had a need, so I filled it.

I had some items that the stock hold-downs supplied with my CNC Router just couldn’t handle.

The main need was to be able to secure items that had irregular sides as well as items on a diagonal.

Here’s what I came up with – maybe it will spark some ideas with other CNC owners as well as those that own t-slot style tables.

Pretty simple really. It’s just some hardwood pieces with a slot mortised in them – I then can use 7/16” bolts mounted upside-down to secure them to the table at pretty much any angle I need.

A couple of wedges just tapped in REALLY secure the item to be worked on – there is NO way that piece will move without removing the wedges.

Easy to make and less than a buck for all the hardware – bonus!

If anyone else has any ideas for this type of table I would be very grateful!

Thank you. I’ve been grinding a couple flat spots on the edge of a carriage bolt and using it upside down. Never thought of a 7/16” bolt. Got to try that one and the rest of your ideas.

Please share any other ideas you have for your system.
