Re: X-Rays. Was Re: [HG] Binding shaft on Reichmann hurdy-gurdy
Hello: I cannot imagine any harming hazard for X-ray machines and CT scans. They are used when studying ingestion of metallic foreign bodies. On the other hand, MRI machines (and HGs with metal pieces) could get seriously damaged. (That is why neurosurgeons use now Titanium clips instead of steel ones).

Re: X-Rays. Was Re: [HG] Binding shaft on Reichmann hurdy-gurdy
I think the problem is more with machines that are hired or rented (like many photocopy machines) or where there are the usual warranty problems of using something for other than the purpose for which it is intended. (A bit like making your coffee in the sterilizing box). Due to the cost of the machines, I can see many people (especially if they don't own them themselves) being very worried at popping a HG under one. Most insurances wouldn't cover any possible damage (dropping the HG from a great height onto the machine) and it would take a brave technician to do the deed knowing they would probably get fired if found out.I like the idea of a vet though. That sounds good.If they can X-Ray King Tut, a HG seems a doddle.

Hi Matt, I often heard about such problems with Reichmann HGs. But I only know, that Kurt Reichmann uses wooden bearings which cuase a lot of problems. I would advise you to try constantly contacting Kurt Reichmann himself about that problem. best Petra -Ursprüngliche Nachricht- Von: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] Auftrag von [EMAIL PROTECTED] Gesendet: Montag, 11.

X-Rays. Was Re: [HG] Binding shaft on Reichmann hurdy-gurdy
Alden, How do you get X-rays? A number of years back I approached a fellow I knew who worked at a major medical imaging manufacturer, who told me in no uncertain terms that if any medical equipment were ever used for such a purpose, it would invalidate all sorts of agreements and be against the law. I found that hard to believe, but he was insistent that there is no way he could ever help me get the image I wanted or that his equipment would be worthless after that. -Arle On Jun 10, 2007, at 11:56 PM, [EMAIL PROTECTED] wrote: The traditional method of installing the wheel was to put it permanently.

Re: X-Rays. Was Re: [HG] Binding shaft on Reichmann hurdy-gurdy
How do you get X-rays? Try a museum. Some have x-ray equipment or access to it. When I lived in Pensacola, Florida I worked as a volunteer on some finds dredged up from a ship that sank in the bay in 1559. Some of the extremely corroded finds were x-rayed and/or cat scanned by one of the local hospitals. At least for the ones I saw, the equipment was temporarily re-located to the conservation facility. Obviously they weren't worried about any warranties being invalidated, and they enjoyed the publicity. http://www.flheritage.com/archaeology/projects/shipwrecks/emanuelpoint/stern.cfm Cat scan: http://www.animalnetwork.org/ANIMAL_NETWORK/Cartoons/Cat_Scan.htm -- Tracie
Re: X-Rays. Was Re: [HG] Binding shaft on Reichmann hurdy-gurdy
I have a friend who is a veterinarian, who does x-rays of old stuff for me all the time, without ever harming the equipment or invalidating and warranty or such. Of course the clinic owns the x-ray machine, and I usually get the images after hours. I don't know what it would cost - I always take the service out in trade (even cleaning around the clinic, if necessary) My advice - don't try people doctors, they are all bound up in all sorts of industry red tape. Find a vet, they are more likely to be helpful. Chris *** REPLY SEPARATOR *** On 6/11/2007 at 8:29 AM Arle Lommel wrote: Alden, How do you get X-rays?

Re: X-Rays. Was Re: [HG] Binding shaft on Reichmann hurdy-gurdy
I know that to be wrong because there are all sorts of industrial X-ray processes used from small items to concrete blocks and oil pipes. He may, however, be right in that medical machines should not be used in that way. You need to look for industrial companies, not medical.The safety rules are different and, probably, the strength of the rays. (Google industrial X ray). A university would be a good place to start.

Re: X-Rays. Was Re: [HG] Binding shaft on Reichmann hurdy-gurdy
Thanks everyone, I figured that a HG couldn't possibly harm an X-ray machine. I don't know why the fellow told me what he did, especially as he was generally very helpful and friendly. I found his response strange, but figured he must know something I didn't -Arle
Re: [HG] Binding shaft on Reichmann hurdy-gurdy
If the bearing is wood it 's probably lignum vitae and that is , up to me , the best you can get one drop of machine oil will do the job I use ballistol oil a brand used by watch makers because this is the only oil witch is basic and so can not get sour you can get it at a gun shop..

Re: X-Rays. Was Re: [HG] Binding shaft on Reichmann hurdy-gurdy
We get our X-rays sort of under the table (so to speak) from a clinic where a friend of a friend is the director of radiology. (Convenient, that.) She didn't seem at all concerned about the insurance implications or whatever. The techs are always very helpful and interested (pecan brownies help here), but I do typically need to bring in my stuff after hours so as not to interfere with patient bookings. We've even gotten some CT scans of instruments - fabulous for showing the exact positions and shapes of braces, the shape of the lute back, and other cool stuff. CT scans do have some shadowing issues with metal pieces - the shaft always looks like the sun's corona during an eclipse, and other metal parts give weird effects, but it's more a matter of interpretation than of harming the machine. It may be that the guy had just been razzed by an insurance inspector or something and didn't want to deal with the hassle.
