Boring Head For Sherline Mill

About two inches is pretty well accepted for the small boring heads, Perhaps the part No. 1 1/2 is a tip off to size.

Tom, on a Sherline lathe boring more than a 3" hole can be an adventure. At 3", the boring head can shake the mill right off the table! However, within those limits the S1-1/2 is very accurate and far superior to the Sherline offering. I have no regrets since owning it.
 
Does anybody have any experience with this boring head:

It certainly looks better than the Sherline product, and it is, frankly, cheap. And this worries me.

Mikey, I agree that a 3" boring head would nuts on a Sherline. But I hear that vibration is a great way to create a weight loss machine:

We had one of these around when I was a kid. We used to like to see who could eat a popsicle while being thrown around.

Never used one but I'd like it more if it used smaller bars. Looks like it should do the job though, and the price is pretty nice.

Marketing never changes, right? The implication that using the machine will make you look like that beautiful creature is very clear. However, on this site we're thinking that if we pulled the belt and cranks off we could make a useful tool grinder out of that sucker!

But look, she is being helped by an actual medical person! It must be legit!

That would be the worlds heaviest tool grinder. About 10 or so years ago we moved the machine from MN to CO. It was a joke gift for my brother's 50th. As we found out, it weighs about 400 lbs. It damn near broke the leaf springs on our 80s era suburban that we used for transporting it.

Back to the topic, I wish the boring head took 3/8" bars, as that is what I have in abundance.

Cheers,

Maybe they should have reversed the position of the models - then it would make sense!

Yeah, I would be concerned about the centrifugal force larger bars will impart on a little mill, not to mention the cost of buying new bars for it.

I bought a Criterion S 1-1/2 on ebay once. It took 1/2" bars but I didn't notice it when I bought it - blinded by the price! When I tried it on my Sherline the shaking when boring a 2" hole was enough to worry me so I asked to send it back for a refund and was really lucky when the seller agreed. I can bore a 3" hole with the same model head and 3/8" bars, albeit slowly, which is why I cautioned you. Centrifugal forces on a Sherline make a difference.
 
Mike,

Thanks. I will keep looking! Since my shop is currently torn apart for a remodel, I have some time...(sad face for now, happy face in a month or so).
