Can I drill v-blocks? - wawoodman - 11-07-2015
Yeah, I could just go downstairs and try...
I need to make a low-profile clamp strap, so I can mill a goove into a piece of round stock. I've seen a number of v-blocks that are bored and tapped, so you can bolt down a bar.
I've also seen a pretty clever C" that's shaped to slide into the clamp slots, which is then tapped for your hold down. But that adds to the width of the setup.
If I can't bore my v-blocks, should I buy a cast iron block? I assume that wouldn't be hardened. Yes?

I've milled plenty of grooves, keyways, etc. in round stock and never used a v-block. Just put it in the vise and tightened it real good.

Just set your round stock into one of the table slots. Use multiple clamps to hold it down and just remove / reinstall them as needed to complete cutting your groove as you progress.

Chinese made V-block and a carbide bit, maybe. Starrett or other quality V-block? Not likely.
Looks like you found your way around the problem already anyway.

Sometimes it's a little too fragile, too short, too small to just clamp in a vise, so I have been known to add a third clamping line by laying the v-block down in the vise to grip it between the V and the solid jaw of the vise. I don't do it with my best No.578 Starrett blocks, but the beat up older ones I've got off eBay, yes.
Also take a look at the way the Starrett No.568 V-blocks are made. The mating clamp engages via cutouts in the grooved sides. I don't mind using the pair that I have to mill smaller keyways or drill cross holes.
