Thread: The Pinocchio of drive centres?

The Pinocchio of drive centres?
The drive centre that came with my lathe (used) has a very long nose. So long that it takes quite the effort to drive it in far enough for the spurs to engage the wood. Looking at pictures of others online, most appear to wear a nose suggestive of a drive centre far more inclined to tell the truth than mine.
Is this just different, or is mine defective? The nose is a separate piece which seats into the drive centre with a taper, though it is fully seated so the issue doesn't lie there. Perhaps the spurs have been subjected to multiple sharpening operations over the years causing the protruding proboscis.

If the suggested remedy is to purchase a replacement, I would welcome thoughts on which type to get. An added bonus would be if I could insert it through/in a VM100 chuck without having to remove it first.

There's nothing wrong with that spur. I have a couple similar, which I use for softer or punky blanks.
But I understand your concern with using it with harder timbers. Which is why I have different ones for them.
As for drive dog plates to fit in your VM100... Vicmarc sells 'em!

You'd need both the adapter plate and one or two of the spurs to suit.

I had similar issues with my standard drive centre so I spring-loaded the point - doesn't matter if it's soft or hard timber now - problem solved!

Looks like a pretty standard Woodfast drive center to me, & in good original condition. If you are using very hard timbers do as Vern has done or if unable to do that then purchase the original or knockoff Steb centers.

I’ve a few like that.
I use a metalworking centre drill in both ends when the wood is a harder species.
Been known to Saw across for the spurs also.

Lance, this is pretty much how I do most hardwood preparation and often with softwoods as well for spindle turning. If you don't have a bandsaw, then almost any handsaw will work. Prior to having my own bandsaw, I used handsaws and even today for brevity I often use a handsaw.

Thank-you all for your responses. It is good to know that not only is my centre normal, but that I can make it work with the techniques shared. Phew, it's always nice when the solution isn't to spend more money.
Mick, I will have a crack at cutting the slots. Thanks for the link, it is a good read for a novice like me.

I used use a spring loaded centre punch to mark the centres and then drill a shallow 2mm hole in each end on most of my hardwood spur driven pieces.
