Hi, I need to absorb as many vibration as possible due to my medical condition so any suggestions greatly appreciated thanks
Very much

Vibration from what?
Oh and welcome to IAP.

Like edstreet, I'm a bit unclear about what type of vibration you are trying to absorb, but I'm going to take a guess that it has to do with turning on your lathe and the vibration you experience using your tools. That said, if I wanted to avoid vibration and still enjoy turning pens, I'd switch over to using a metal lathe. Metal lathes have tool holders so you do not have to stay in physical contact with the lathe or the tool. It will be a bit different than using a wood lathe, but if you're only making pens, you can do it very easily and still create beautiful pens.

Couple of tips with the info provided;
Make sure your work AND lathe are balanced.
Try to work with round stock rather than square.
Light cuts and keep those tools shape, the less you have to press, the less vibration you'll feel.
Hope that get's you started!

Sharp and HEAVY tools dampen vibration. Over 1" gouges, skews, etc.
Yes, round is better than square. Take off corners of blanks on a bandsaw (with a jig for safety) or a stationary belt sanding station.
If you are super-sensitive, it may make sense to add weight to the stand of your lathe. The greater the weight, the more force it will take for it to move (vibrate).
Welcome to IAP---hope you can ENJOY turning while still avoiding endangering your health!!

Sorry guys, I have a condition called Rsd/crps so vibration from motor, lathe trying to miminmise all vibration to stop flairs. Thanks

Oh by the way thanks for suggestions
Anti vibration gloves-half gloves.
Toni,
These can be purchased through a safety supply company.
They are 1/2 finger gloves, with gel in the palms. Dampens vibrations when drilling and other types of operations.
Grainger would be one place, they're the most expensive around. MSC should have them, also mcmaster.com
Sorry I left mine in tool cabinet at work when I retired. I believe they would be safe to use around a lathe. They're snug fitting and would be difficult to catch onto something that is spinning.
Send me a private e-mail if you're unable to locate and I'll find them for you.
all the best,
Charlie

Motor vibration can often be reduced by installing a link-belt.
I hope that helps,

Yikes. Sorry to hear that you have this.
One thing that really sticks out to me is sandbags, cast iron and concrete. Those 2 things readily absorb energy. General rule of physics is add weight via mass.
Things like sand bagging the lathe stand in many locations will help greatly with the lathe.
Rubber grips can be added to the lathe levers, not only do they help with vibrations but also with usability.
Rubber floor mats help greatly as well.
Tooling for the lathe, i.e. drilling, will often remove other tools needed and allow you to increase the ergo mods that is needed.
As previously mentioned large wide and thick chisels helps a very good deal.
One final rule you should apply is if there is vibration in the lathe then your speed is to FAST. slow it down. I was talking to jet this week and the 1221 has anti-surge technology in the motor controller to prevent this very subject. Most here may tell you to turn at 3,000+ rpm but with what you have going on here I would suggest you cut that in half, 1,500 rpm or lower is going to be your friend.

Thanks heaps. Very much appreciated
Couple things to note...floormats do not help with repetitive stress injury or carpal tunnel syndrome, but they will help your feet! Resting of those joints and connective tissue will help. The bad news from a medical standpoint is that unless you have corrective surgery, CTS/I will not heal well without prolonged rest and cessation of the activities that caused the initial injury...read into that, a year off. RSI is about the same, doing the same thing all the time needs to be changed to not doing the same thing all the time.
While I appreciate Ed's medical experience and education...it just may not be practical for your application. A reputable GP/FP in your area should be able to guide you to a correct healing process.

Hi Toni,
I also have CRPS, as an after effect of surgery on my left hand to excise a Dupuytren's contracture
That was some 6 months ago.
After all the usual hand therapy, the swelling, pain, colour change, and all that crap continued, so they started me on a course of Stellate/Ganglion Injections, into my neck where the nerves enter/exit the Spine.
After 3 of these over 4 months, the results were very favourable.
However it has now regressed, and I am scheduled into day hospital on Thursday for another go.
I have not been turning for a while, I have used the time in between medical appointments, to clear out my Garage/Workshop, and make some much needed equipment to improve the use of space.
While vibration hasn't cause me any problem, I would like to add to some of the suggestions you have already received.
I agree with Ed,
1. Sand bags on the lathe stand or bench are excellent, as apart from the mass, that will resist movement, the individual grains of sand are almost fluid and absorb a great amount of energy within the bags.
2. The suggestion of using flap disk sanding to round rectangular blanks is sound, provided that the Angle grinder doesn't impart too much vibration/torque of it's own.
3. Regarding turning tools, as well as using broader/larger tools to ride over a bigger area, and the smaller bumps.
3.1 consider wrapping the handles with Tennis racket wrapping, or golf stick wrapping. These also absorb a great amount of shock and vibration.
4. Finally, remember that sharp tools do not require a "death or white knuckle grip" but can cut, being held lightly between a couple of fingers (with a bit of practice).
Are there be other turners, in Townsville or a Mens Shed who could give you some assistance as and when needed? if only to round off your blanks?
Hang in there.
Thoughts are with you,
Brian.
