jmsj I don't know what printing technique you plan to use for printing rth stickers but in offset printing - designs 4, 5, 6 and 10 are also considered to be in one color. Some of them are shaded but still in one color. Gray is also considered black - lower percentage black but still black. If you consider “sieve” printing (I am not sure about term) I know that there should be no shading - but no 6. has no shading at all. Shading effect is done with black lines only. Same thing could be done with no. 10 (5 and 8 also). Problem is going to be prospector. Especially, because it's low-res gif. I could try to redraw it in some vector-based program but it is going to be difficult to be precise 'cause it is so low res. Thank you for your help. It is very valuable. Zoran

That last one of Zot's is sweet! It would work great as a white on clear sticker or white on dark screen print for a t-shirt or something. The only hassle may be the 3D part of "RTH". It introduces an extra colour (grey) That means a 2 layer rather than 1 layer screen print which can be done, no problems. It will just cost more. Hey Zot, can you reproduce that last one, but make it white on clear and can we see what it looks like with the "RTH" being 2D rather than 3D with no grey? I'd like to see how it looks. Thanks mate, Mike No prob.

I liked what LCARS and sands proposed and took freedom to graphically modify their ideas. Hope they don't mind. What do you think.

I have the same wheel. I got it last November, and it is still working. I think it is going to work more, but not as aggressive as at the beginning. I find this wheel now very good for more sensitive rocks like opal and softer ones. But when I am grinding tough chalcedony wheel starts to grind a little slower. I find this wheel very good when you want to do something more precise in first step. I plan to buy next time 80g wheel and I think that one is going to last more. I think that my 120g jadecarver wheel is now 140 or even 150g wheel. And, yes, I do grind a lot. Otherwise if I ever get enough money I would go for sintered wheels.

Oh, wait. I have something like this in my office. I didn't know I have so wealthy arranged office. Actually this dyed agate, khm, I mean - amethyst slab, is not mine. Belongs to a professor. I didn't know he has so much trust in me to entrust me such a valuable specimen. What you think would he be happy with the half of the amount 499,5$. I'll pay the shipping costs ;D. Zoran the wealthy guy

Granite is a rock and its mineral composition may vary a little and its hardness also. But main minerals of granite are feldspar minerals and quartz and they give granite hardness somewhere between 6 and 7 on mohs scale. Marble is metamorphosed limestone so its hardness is around 3.

Thank you all, very much. I really appreciate it. Joe, I made that label myself. Designed it on comp, then printed on ink-jet printer and then plastificated. Here is label close up. I levelized the working bench today and, believe me, that is very good thing to do. Vibrations are minimized. I put rubber sheets under bench's legs. That also helped a lot. I plan to make some kind support for forearms to. Thanks. Zocky

I already posted this in original tread ([ forum.rocktumblinghobby.com/index.cgi?board=general&action=display&thread=1163814115) but I think that would be useful to open another thread to encourage everyone that plan to make their own lapidary equipment. Grinder/sender is finally finished. There are some small adjustments left undone, but here it is. And how quiet it is. Comparing to my earlier grinder this one is music to my ears. I can even listen to the music while working on it. How nice. Total cost specification for my cabbing machine: Bearings 5$ Shaft 15$ “Inox” (stainless metal alloy) + bending and welding 40$ aluminium sheet 5$ + some minor costs for: paint, screws, plastic tubes and valves (aquarium type) So it makes around 60-70$ for arbor, and of course much of your time. To make my grinder/sender work I also bought: 1 ½” metal diamond wheel (63$ - jadecarver.com/DiamondTools.htm)1 ½” expandable drum (40.75$ - from Eloxite – www.creditcardcastle.com/cgi-bin/template.cgi ) 1 ½” diamond belts (38$ each – from Daniel Lopacki – lopacki.com/belts/) (I bought 220, 600 and 1200 grit belts) for 3000, 14000 and polish I use diamond paste and cerium polish powder on vertical lap. But when I get some money I might buy some more belts (3000, 14000 and even maybe 50000 – they cost the same at Daniel Lopacki – 38$ each). Of course I forgot to mention new 100$ motor. You don’t need to buy new one if you have spare one (washing machine motor for example). I don’t regret 100$. This one is so quiet. That makes total costs for my cabbing machine around 284$ – 70$ (arbor) + 114$ (diamond wheel + expandable drum plus diamond belts) + 100$ motor. If you add 3000, 14000 and 50000 diamond belts total costs are going to be 114$ higher. Not bad comparing to costs of one Diamond pacific cabber. I didn’t count shipping costs because they are much higher in my case, not to mention customs. If you are buying from USA I think that they are going to be much less then 100$. Of course total cost could be much less if I chose to use SiC wheels and belts. But diamond really makes the significant difference (yes I couldn’t resist – I did make a cab last night – oh, how much easier it is to make one). It took me much longer, but I think that one arbor like this could be done for a weak, even less (depend on amount of your spare time). And, of course, if I could make it, anybody can. Thank for looking. Zocky

Thank you , Dave. That was very interesting and helpful. I would be very grateful if you could take some pictures. I agree with you that bigger saw is more useful, but money is going to be an issue here. I consider making saw that way that should accept 14" ant 16" blades. Thank you very much. Bam, Bam, I agree with you – if everything else fails this is going to work for sure. Maybe to use gravity feed as a reserve. Thank you.

Thank you, Daniel. I just found that someone once used, on homemade slab saw, motor from barbeque. That kind of motor has 13W power. I think that would be adequate power, maybe a bit stronger.

I am considering making 14" slab saw. What I need to know is how much power is needed for power feed motor? Any help highly appreciated. Thank you.
