Questions & Answers
The outer shims' shoulders are near the top of the hole, so there must be enough room for the wedge to go all the way through without bottoming out. Based on the diagram's dimensions, a minimum depth of 4" is required. If the wedge does hit the bottom, it can be removed by drilling a second hole alongside it, but this is something you should avoid. A hole of 0 is also mentioned in the description. It's also incorrect to say that it's 5" in diameter.

Yes. Determine which way you want the split to run and then position your wedges so that the wedges push the feathers apart, splitting the rock in that direction. I discovered two things: Make your holes 5/8" in diameter rather than 3/4" in diameter. I tried 3/4" holes, but they weren't as effective. Also, ensure that your holes are sufficiently deep. If your wedges hit the bottom of the hole before the split begins, it's a bummer. Aside from that, it's fascinating to see ancient technology in action.
Wedge measures about 4 inches in length. 1/4" in length

the wedges should be spaced about 8" apart bosch SDS- Max rotary hammer going about 4 with a Dewalt 5/8 "4 cutter" bit. 5" deep. I'm not convinced that an SDS-free environment is possible. For this many holes in granite, a larger drill would be ideal, as granite is much tougher than concrete. I think 5/8 is a little big for these; they worked better once my 5/8 bit was shot and I had to use a 9/16 bit instead. They're actually 16mm, but they're sold as SAE sizes. 16mm refers to when the wedge is halfway inserted. Next, I'm going to try the Makita "6 cutter" bit. If I were using these for a job, I'd probably skip the "5/8" wedges and instead get some larger ones for the big splits, followed by some "9/16" wedges and a sds max-size drill bit. sds plus adapter so I could drill the "9/16" wedges with a dirt cheap drill bit like the DW5437B25 bits.
Several large stones were split with the help of these feathers and wedges. So far, three have broken. I'm driving these in with a 10lb sledge hammer after setting them firmly with a 4lb hammer. The ones that have broken, I believe, have been struck off- center. If a hammer is struck/pinched, the rubber rings that surround the feathers can break. br>br>A 5/8" drill bit is required, as previously stated. "DEWALT SDS Plus Bits, Rock Carbide Tip, Hammer, 5/8-Inch, DEWALT SDS Plus Bits, Rock Carbide Tip, DEWALT SDS Plus Bits, DEWALT SDS Plus Bit DW5446 (Inch)". At the very least, get two of them. Before sharpening, they can handle about 8 to 10 holes. I recommend going at least 5-inches deep when drilling holes for these feathers and wedges. inches long and wide This should prevent the wedge from bottoming out, which could result in the wedge breaking. br>br>In general, these are a good value. I went out and bought a new set.

Not only are there loose rocks in my backyard, but there are also buried boulders. So I began removing the grass and weeds, and yes, I discovered boulders large enough to require splitting into three sections. To make them easier to handle and remove, they've been broken down into five pieces. I began by using a 3/4" cold chisel and a mini sledge hammer. I can't tell you how difficult it is to split a rock this way, let alone how much it hurts my wrists. br>br>I knew there had to be a better way, so I went online in search of one. I came across a video of feathers and wedges being used to split rocks. This was a new term for me, but it appeared to work. br>br>I came across this set on Amazon and immediately placed an order. br>br>I have to say, this method of rock splitting is a lot easier than pounding the rock with a cold chisel over and over! Drilling all of the holes across the face of each boulder proved to be the most difficult part. It's just a matter of alternating hammer hits on each wedge used after the feathers and wedges have been inserted, and you'll hear it. As the boulder begins to crack and eventually split, it is nearing the end of its life. br>br>I discovered that it's best to keep the holes in a straight line across the face, and the pressure from the feathers and wedge will take care of the difficult part. br>br>It was wonderful to discover something that made this job so much easier.
Several tons of volcanic rock were split into manageable sizes using these wedges. They work well with an 18mm hole. Unfortunately, Amazon's "guaranteed delivery" deadline was missed, so the majority of the work was completed using an earlier shipment of similar wedges from an ebay supplier. br>Here are a few pointers: Use them on a single side of a rock to start a crack that spreads to the opposite side; they make no sense on opposite sides, and they make even less sense on adjacent sides because they will "fight" each other. I think it's also helpful to put a few closer together to form a starting point for a crack, especially if the rock is soft (as ours was in places) to avoid them crushing the side of the holes without splitting between and below them, and I think it's also helpful to put a few closer together to form a starting point for a crack, especially if the rock is soft (as ours was in places). Once a crack begins, it will be followed by a series of wedges that are spaced further apart.
Several boulders were broken up by me - Each one weighed a couple of tons. When I was finished, the wedge/feathers appeared to be brand new. They are clearly made of high-quality materials. The steel is of high quality and has been properly tempered.
In my yard, I have chert boulders, which are similar to flint but have softer areas mixed in. The chert is easily broken with these wedges. A large hammer isn't required. Swinging a blacksmith's hammer with one hand and watching the rocks split should suffice. br>br>I used a one-star rating system. To drill the holes, use a 3/16" rotary hammer. It would have taken an eternity to use a hammer drill.
This is suitable for small 2-person households. 3 feet of rocky terrain Rent a jack hammer if you have a boulder to move.
Look at the feathers and wedges, as long as they're hardened steel, you're good. I've been a stone Mason for 40 years and am used to the old style, but I must admit, these 0 ring ones work well and you never have to look for your feathers. I've already split around 20 tons of granite blocks with no problems, and I'll buy more.
