Rockler640762 Shelf Drilling Jig 1/4''

I thought this was a great idea to add lots of shelf pin positions for the cupboards I've been building, however in practice it isn't consistent. I started by drilling 4 level holes for one shelf and used the peg to start from each one. After about 1m up, the pins were about 2-3mm out, meaning the shelf wobbled diagonally. No matter how careful I was, I couldn't get the holes level. I resorted to using a laser level to mark where I actually wanted my shelves, so this jig is now somewhat useless. It's fine if you don't need consistent level holes over a larger span, but for my case it wasn't good enough. Hope this helps someone.

This a brilliant jig. No fuss. Make sure to buy corresponding 1/4 inch pins

1/4 hex shank slightly too big to fit in dewalt impact driver or any other hex socket. Had to use regular drill. Hard to find 6.35mm shelf pin in UK. Wish I could return it.

It seems like a solid bit of kit at first but there's just enough slop in the fence to make it useless for larger jobs.There's a 1m think grip strip on the fence to help with keeping it in position, but it also means that pressure holding it in place at a different point causes it to move off line slightly. Thats not so much of an issue if you are doing 10 holes but I had a 26 hole run and by the last hole one side was a hole hole width (or 6mm) off from the other side.
