{"product_id":"engraving-ball-vise","title":"Engraving ball vise, 3 or 5 inch","description":"\u003cp\u003eYou are setting a stone, or cutting a letter into a signet ring, and the part keeps shifting under the graver. A ball vise fixes that. The jaws hold the work, the ball sits loose in its base, and you turn the whole thing to whatever angle the tool wants without ever letting go of the part.\u003c\/p\u003e\n\n\u003ch3\u003eHow it works\u003c\/h3\u003e\n\u003cp\u003eThe body is a ball of chrome-plated steel with a parallel-jaw vise built into the flat top. The ball drops into a moulded base and turns a full 360 degrees, and because it is a ball it tilts as well. Loosen the jaws with the hex key, seat the part, tighten. Then you have both hands on the tool instead of one on the tool and one holding the job still.\u003c\/p\u003e\n\n\u003ch3\u003eWhich size\u003c\/h3\u003e\n\u003cp\u003eThe difference that matters is how wide the jaws open and how much the thing weighs.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003e3 inch.\u003c\/strong\u003e Ball 78 mm. Jaws open to 54 mm, which is 2.13 inches. With every accessory in the box it weighs 4.4 lb, about 2 kg. On the bench it stands 97 by 97 by 85 mm.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003e5 inch.\u003c\/strong\u003e Ball 127 mm. Jaws open to 98 mm, which is 3.86 inches. It weighs 20.3 lb, about 9.2 kg. On the bench it stands 145 by 145 by 170 mm.\u003c\/p\u003e\n\u003cp\u003eNine kilos is the whole point of the 5 inch. If you push a graver by hand the 3 inch is enough. If you tap the graver with a hammer, the mass is what stops the vise walking across the bench.\u003c\/p\u003e\n\n\u003ch3\u003eWhat comes in the box\u003c\/h3\u003e\n\u003cp\u003eThe attachments are pins, stepped jaws and ring clamps that drop into the holes in the jaw face, so the vise grips a ring band, a flat plate or an awkward casting without marking it.\u003c\/p\u003e\n\u003cp\u003eThe 3 inch, 30 piece kit: 3 ring clamps, 2 large plate clamps, 4 medium plate clamps, 4 small plate clamps, 4 long rubber pins, 4 short rubber pins, 8 small oblate pins, and a hex key in a plastic box.\u003c\/p\u003e\n\u003cp\u003eThe 5 inch, 35 piece kit: 2 ring clamps, 2 large plate clamps, 4 medium, 4 small, 4 long rubber pins, 4 short rubber pins, 8 small oblate pins, 5 large oblate pins, and a hex key in a plastic box.\u003c\/p\u003e\n\u003cp\u003eThe 70 piece and 69 piece kits are the same vise with more of the same parts. We do not have an itemised list for those two, only the count. If the exact contents matter, write to us before you order and we will get it from the supplier in writing.\u003c\/p\u003e\n\n\u003ch3\u003eShipping is different on this one\u003c\/h3\u003e\n\u003cp\u003eThe drill press comes from overseas and takes about two weeks. This does not. The supplier holds it in a warehouse in the United States and quotes two to nine days. That is their figure, not ours, because we have not yet timed a shipment. The first order will tell us, and the real number goes here.\u003c\/p\u003e\n\n\u003ch3\u003eWhere these numbers come from\u003c\/h3\u003e\n\u003cp\u003eThe ball diameters, jaw openings, weights and dimensions are the maker's published specification, copied as printed. We have not measured a unit. The moment we have one on the bench, anything that turns out to be wrong gets corrected on this page.\u003c\/p\u003e\n\n\u003ch3\u003eHonest limits\u003c\/h3\u003e\n\u003cp\u003eThe ball rides on a screw-set seat underneath. Owners occasionally report one arriving tight enough that it will not swing freely. If yours does that, write to us within 30 days of delivery and send it back for a full refund of the item.\u003c\/p\u003e\n\u003cp\u003eThe supplier describes the base as reinforced plastic, not cast iron. Its job is to cradle the ball, not to take a hammer blow on its own.\u003c\/p\u003e\n\u003cp\u003eIt does not bolt to the Mikrabench drill press base. This is a hand-work fixture for engraving, stone setting and small repair, not a machine vise.\u003c\/p\u003e","brand":"Mikrabench","offers":[{"title":"3 inch, 30 pieces","offer_id":46212024664255,"sku":null,"price":129.0,"currency_code":"USD","in_stock":true},{"title":"3 inch, 70 pieces","offer_id":46212024762559,"sku":null,"price":149.0,"currency_code":"USD","in_stock":true},{"title":"5 inch, 35 pieces","offer_id":46212024795327,"sku":null,"price":169.0,"currency_code":"USD","in_stock":true},{"title":"5 inch, 69 pieces","offer_id":46212024828095,"sku":null,"price":189.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0760\/5826\/3743\/files\/S28514f0884bb485e93a6cca12e250997g.webp?v=1789566886","url":"https:\/\/arvonelle.com\/products\/engraving-ball-vise","provider":"ARVONELLE","version":"1.0","type":"link"}
