  1. If you have access to a Hot press with controllable pressure then you can go the high tech route. Pressure is not as critical as temp when you go this way. In the high tech way (Solid phase Diffusion bonding) Pressure is there to ensure that the surfaces of each layer make full contact with each other so the grains can grow together across the weld zone uniformly across the entire billet. These alloys are soft and get softer when they are hot. They do not provide much resistance to pressure while hot. So unless you want to squish the billet right off keep the pressure low. You can start out
  2. Hi Chuck, Jasper is a high silica mineral with properties like glass. It is not the same as slate. Slate can be primarily silica, but it is put together differently than Jasper, Quartz, Chalcedony, agate, Flint and so on. These minerals lack the chalky abrasiveness of Slate. It is this fine chalkiness that grinds the ink so finely. Slate can be made of a large variety of minerals including Silica. Any mineral that nature could turn into sediment had the potential to become slate if the right geological processes happened. The stones unique and excellent ink stone properties come from the way
  3. Hi Donn, I have never carved jade, but I am an avid Rock Hound and crystal collector that lives in California. I have a handful of California Jade specimens some from the Sierra Nevada mountains and some from the north coast beaches. How do you determine the quality of the "felt"? do you have to work the material? Thank you, Patrick
  4. I have not made any yet, but I will share my progress when I get some hair. I have some thoughts for process that might make it too easy Patrick
  5. I was considering getting my own from Japan through contacts, but I use these so much and they are so expensive I decided to go ahead and make them. I think I can get the hair for free, but even buying it, the brushes can be less than a $1 a piece. It will be nice to control the brush size and stiffness regardless. I will post pic my home made brushes of course Thanks though to Jim for the public offer. Patrick
  6. I have a Presto actually it is the GRS 850. It is the same unit, but the GRS label made me pay too much for the tool. Any how the unit performs great. I have been using it for 5 or 6 years now without any maintenance. It does have enough torque to work metal, but its performance in soft gummy metals like copper is very slow. It actually works fairly well on steel. I don't use it much any more, but I would miss it if it was gone. I would recommend the Presto if your looking for a turbine with more torque. Patrick
  7. The eye stalks are going to have to be constructed with a telescopeing tubes patrick
  8. I have an aunt who dabbles in gourd carving she has a turbo carver. It is nice on gourds almost useless on metal. It has an extremely high speed and extremely low torque. Can't say much about its performance in wood as that is not my medium. It is inexpensive and easy to repair, but personally I can't find any use for so little torque. They say it will carve a chicken egg without chipping or cracking it. Patrick
  9. Thank Karl for that one. I don't have the time it must take to find all this stuff Karl finds. He must search the internet 20 hours out of the day. Patrick
  10. Just a quick post while the generator is cooling off my fridge. Having a blizzard here and no power. Perhaps tradesman like plumbers are not that great of an example. Besides the reasons that Ric stated they also have fairly high over head compared to a person with some lights and a handful of chisels working in there garage. Some of us obviously have more overhead than others, but carving can certainly have low entry cost. I like to look at Professional engravers as an example, because that is fairly close to what I do (Japanese style Engraving/carving) In the US Engravers are fairly comm
  11. I know three people that have Machines like this. Three dimensional mills that use a pattern to guide the mill head. They can change the scale without electronics. I have only seen one of them run. They are all fairly old and basicallly retired, the machines that is but all still work. I personnally am interested in a CNC conversion setup for tooling and machine work for various hobbies of mine. I want to build all sort of machines. You can get a some nice mill set ups with high resolutions stepper motors, complete with computer and software for $10-12K these days. Shop Task has an interesting
  12. My connection is not good lately or I would look this up myself, but try looking up Patents for the lathe. You can generally get detailed mechanical drawings of such devices. Regards, Patrick
  13. Those pages are lovely, but better to simplify than have nothing at all. Get something up that works add to and improve later. Have you considered a Blog format? They are very easy to work and update yourself at lease for a begining or temporary way to have your own space. As you know I work on my own pages. Very basic as far as websites go. My Front page program ceased to work properly with my server so I switched to dreamweaver and started my website from scratch. The Learning curve is steep, but not impossible. I don't want to rely on anyone else nor do I like delays when I want to update
  14. Hi Karl your links have been very useful lately. I was just about to purchase the Japanese legends book you posted. Now I have a free copy! Mr Toshi is within driving distance of me and I would really like to get ahold of him and introduce myself. I can't find any form of contact on his Blog. Does anyone know how to get a hold of this guy or did I just miss it? Thanks again, Patrick
  15. These are solid tungsten carbide burs, no diamonds. patrick
