Its like a bike that was advertised in perfect condition but crusty as hell. I passed on the bike.

There are two good size pieces remaining from the large slab for another day. You have been photo bombed in the worst way. Sexy cabs or abs?

A very nice array of the biggies and beauties, sort of like a sampler box of candy. But a great way to learn what you like and what you can do with different types of material. Sharing the diversity of this avocation is part of the game. You get to enjoy a big swatch of lapidary too.

It would be more informative if we had a fresh cut or windowed view of the internal, non eroded structure. I'd vote no on the basis of too little information.

I know there is a way to hide the posts of specific members. I can't remember how to do it, but I can tell you there are a couple of members that I've banished from my screen. Instead of following, I'm running the other way.

Clearly we share the same techniques and tricks. Yes the hp vice can bind a bit short of a firm clamp and all the tightening in the world can let the rock jiggle. This probably in part to rock crumbs in the vice grooves or gremlins. That's where you tapping is applicable. The issue of a blade first contacting a shallow angle is best addressed by making sure the saw is started with the stone close but not in contact with it. Thus it is spinning straight and cuts the correct groove and is not wedging the blade laterally. Slabbing is an art and probably as important to the economics of lapidary as the final steps. Cheers.

I do my hammering on hardwood wedges. The wedges are only inserted when the rock is "tight" and then hammered (tapped) in and if possible tightened a bit more. My old custom saw has a vice tightened with a 3/4" open end wrench which gives me some leverage; and I seem to recall that Tommy joins me in using a box wrench to extend the squeeze of the Highland Park vice on the tough ones. Your tapping is a good option too.

Another consideration is the position of the blade slot relative to the holes. That too could be moved if needed.

The best trim saw is like the best bicycle helmet, its the one that you have available and will use. If you can find a 10 or 8" that would be best. A good blade can make a moderate saw work well, but any saw with a bad blade will work you and the motor too hard. All trim saws can be messy because they lack a top, but its possible to fabricate a shield in front of the blade on most saws so that the operator does not have to take a shower with every use. Ditto for some side protection. And learning how much water (or gasp oil) to use in the tank will certainly limit the mess from lubricant spray. If you can find something really cheap, why not try it and get some experience as to what is important to you as for features to shop for when you spend real money. Happy sawing.

I would not fret the cleanliness issue. When you fill it with oil, some of the stuff bothering you will free up and settle out or float out on the first cleanout. If your bearings have grease zerks, I'd hit them with a grease gun, but if not, don't worry until you hear noise or sense resistance. WD40 is not a lubricant. But it is a good solvent for cleaning like you are doing. If you really need lubrication count on oil or grease. Again your tank oil will lubricate things like vice rails and threads of feed screws. I'd fill it up and run it on small rocks and little jobs until you get a feel for everything being functional and then enjoy.

Shooting blindly with too little info, I'd lean toward a terminal digit of something large fossil or not ( toe).

Have someone handy with a table saw, cut a whole bunch (carefully of course) of hardwood wedges to keep at hand. You will soon learn what sizes and shapes are most useful but sharp and not to thick are probably good candidates.

It might be easy to improvise such a mod to a vice like the standard HP setup. I like the fact that it grabs horizontally and not vertically. I can envision a lot of pressure and distortion on those holes if used often and hard.

What is unique about the slab grabber type of mount is the triangular slots that are able to securely wedge the often thinned and triangular edge of a nodule or sloping rock that has a somewhat flat face. The standard vice doesn't have that slot for the rock edge to fit into. There is another version which involves machine screws that have sloping heads that accomplish the same thing. Here is another shot of the one I'm using. 20231002_130132 by Thomas Fritts, on Flickr

I've always stubbed rocks on wood to mount in the vice when slabbing, but today I had several pop off the mount. The problem was due to agates that had been face polished by a foreign vendor and they may have been treated with paraffin or something else to make them shiney. So I reached for my largely unused slab grabber and was greatly impressed. It was fast to mount and nothing slipped. I probably mounted a dozen stones in one session.they were small and each only produced two to four slabs. www.flickr.com/gp/186066986@N08/jKq1JW31d7I have one small one made by star diamond and a larger one made in a minn. Workshop they are similar in design. Another option for those tricky rock cutting challenges.

Your proposed gold ore crusher will do just that. I'm pretty sure it will produce powder and very few usable rocks.

Looks good to me. You now get the real fun of finding out what beauty (or dud) lies inside rocks! Ditto on sufficient oil Oil spray sometimes depends on surface shape of rock. You can build a shower stall like box around and access during run through a smaller door. Congratulations on the beginning of more fun and productive efforts.
