Wedges and feather shims stone splittercomes in handy when you want to split a larger stone. It forces and squeezes out the free space every time we hammer it, and split down the larger stone into half.
Wedges and feather shims are normally used to split hard stone, rock, granite or even concrete.
The feathers are wide at the bottom, and tapered and curved at the top. When the two feathers are placed on either side of the wedges/plug, the combined width of the set is the same at both ends.
HOW TO USE:-
Determine the grain of the stone, drill several holes along the grain and remove residual powder inside the hole.
Align the stone splitter and put it into the hole.
Hammer the end of the wedge to the split stone.
Attention: Keep your drilling straight, hole depth MUST be longer than feather. Wear necessary protective gear, take extra precautions when the rock is about to split to avoid accidents.
1 x Stone Splitter (Wedge & Feather) - Various Sizes Available
Easy to use and very effective in splitting several large rocks that completely stopped my excavator.
These wedges work great, we were building a wall with big granite blocks and some of them needed a little off the end or wherever to fit right, these did the trick.
Used these to break up a big boulder in my back yard. I rented an sds roto hammer with a 9/16" bit and drilled away. It was hard work but we got it. Never busted an o-ring either
This set of wedges and feather shims arrived promptly at my doorstep. I am a professional (state licensed) geologist, so I know lots about rocks and breaking of rocks. As an equestrian, I am deeply involved with maintenance of horse trails, replete with lots of rock and boulders that need to be be broken so that the trail-bed will become safer for horses.
The best battery-operated drill appears to be the Makita drill. It accepts multiple diameters of carbide drill-bits and various dynamic chisels to chop-away the surfaces of the horse trail-bed.
The only uncertainty was this. What is the correct diameter of the carbide drill-bit? I did not know, so purchased several different drill diameters. Answer learned the hard-way: The optimum drill-bit diameter is 5/8-inches. Anything larger has too much space for the wedges, and anything smaller is too small to fit the wedges. So: the voice of experience: Be ready with your 5/8-inch rock drill bit. None larger, and none smaller. The voice of experience.
These wedges worked beautifully. Make sure you drill the holes deep enough. I made the mistake of only drilling them about 3in the first time to allow the wedges to fit...didn't work. You need to drill about 5in deep holes to allow for the wedge to be hammered down past the wedges, otherwise the wedge will hit the bottom of the hole and not work properly. Once I figured this out the rock split effortlessly. The steel was strong and did not bend, the bands held up find, remember, your not beating on these, just tapping one at a time. Very important to spread out your hammer taps evenly among the wedges and the boulder will just split. Wonderful product!
Works as supposed to!
Good quality and worked very well with the Bosch drill bit.
