What you read was sand around the top of the holdfast shaft?
The dog holes are in the rail and they are 4 1/2 thick. That is where I have most of my problem but a few of them do hold. I will try to sand the posts and see what happens. Thanks for the tips.
Keith,
Sorry for not getting back to you. Was out this weekend. Here's what I read on the ToolsforWorkingWood website which sells the Gramercy holdfasts:
"Note: we have discovered that while the holdfasts work great they will work even better and in more benches if you just rub a little 150 or 220 sandpaper around the stems (not up and down, round and round)"
Here's the link:

I also picked the following comment up off a forum called Family Woodworking (which sure looks a lot like SMC..)
"I seem to remember an "Old Codger" telling me something about the thicker the top is, it needs to have a "SLIGHTLY" larger hole than a thin top to get them to hold, since the holdfast cocks off of vertical and binds on one side of the hole at the top and at the opposite side of the hole at the bottom. With the THICK top and a small hole, the holdfast can't cock sideways enough to get a grip."

Re: chamfers - Asthetics are important! I was wondering what bit of woodworking wisdom I was missing out on. I hadn't really considered what I would do if I messed up a dog hole when I drill my bench top. Maybe now I have a plan... Thanks!
