Q: I unintentionally allowed the properly of a drafting desk i am refinishing to fall over and hit the concrete floor in my garage. regrettably, one of the vital cast-iron channels that enable the precise to trade angles broke into 5 pieces. I cannot discover a replacement. I referred to as a few welders, and both observed the pieces could not be welded because the part became cast iron. I have idea about attempting J-B Weld, but i might likely botch it and am not certain it could cling anyway. Any concepts?
A: Repairing antique hardware or changing it with a brand new piece that looks the equal is a challenge for a lot of furniture restorers. It’s crucial to both the look of the piece and its performance.
When replica hardware is accessible, that’s usually the least difficult and least-expensive option. however even corporations that specialise in the copies cannot probably inventory parts that mimic all the hardware patterns which have been produced over the years — as you have found. Hardware agencies do make mechanisms for tilting tabletops, together with some that evoke a vintage look. however they don’t have the sleek arch that your broken piece once had. That leaves you with two alternate options: restoration the damaged half, or replicate it.
the dual-tube, normal method of J-B Weld usual ($ eight at Lowe’s) is one choice, supplied the end surfaces are at least one-eighth-inch thick. The normal method is the company’s strongest epoxy, rated for withstanding three,960 pounds of drive per square inch in case you had been to are trying to drag the pieces apart, observed Gena Hansen, who works in J-B Weld’s customer carrier department. you possibly can need to clean the surfaces first with an acetone or lacquer thinner (don’t use alcohol), and then roughen up the cleaned surfaces earlier than you mix the two add-ons. After the epoxy units, you may file or sand it clean and add a coat of paint to make every little thing seem to be uniform. but given how skinny the broken components look in the photograph you sent, it appears like a risky restoration. fortuitously, you have other alternatives.
despite what you had been informed, it may be possible to have the constituents welded together, although for this procedure, the damaged ends would need to be just a little thicker: as a minimum three-sixteenths-inch. Welding brings metallic collectively at the molecular degree, so it is stronger than a joint glued with even the strongest epoxy. Welding cast iron may also be elaborate, even though, which is why some organizations don’t do it. however Peggy Wright, who works in earnings for Architectural Iron in Milford, Pa. (800-442-4766; looked at your photograph and observed her business could do it, the use of a welding rod it is ninety nine % nickel. at least three sorts of welding rods work on cast iron, however the competencies of the usage of 99 % nickel is that it may also be sanded clean later to provide the hardware a complete seem, she stated. Wright estimated that the fix could cost around $85. however to get an organization estimate, you could need to send the elements to the company.
or you might get new, custom hardware. To make a piece of solid-iron hardware, a corporation would beginning with a mannequin (ideally, the piece you want to copy) and then use it to kind a mildew for molten metal. Two groups that cast hardware even when a customer wishes handiest a single piece are Ball and Ball in Exton, Pa. (800-257-3711; ) and old Hardware and lighting in Port Townsend, Wash. (360-379-9030; vintagehardware.com ).
to manufacture custom hardware, these agencies want to beginning with an intact piece, since the mildew will choose up all the details — even destroy marks if the fashioned became glued collectively. old Hardware warns on its site that copy castings wind up smaller than the originals, since the molten metallic shrinks as it cools. but the change is “only a hair’s width,” so it’s not some thing to worry about, observed Victoria Rothschild, the manager at antique Hardware.
At antique Hardware, replica castings from an customary sample birth at $65 for one piece. there is a further charge if you send damaged pieces and need the enterprise to attach them to make the mannequin. To get a value estimate, you possibly can should send the part or parts, plus $10 to cover the assessment.
although Ball and Ball does customized casting, Robert A. Ball, part of the household partnership that owns the enterprise, recommended that instead of trying to forged a substitute on your certain hardware, it could be more advantageous to duplicate it from sheet metal that matches the thickness of the common. “We might solid just about anything, however I don’t suppose this part is solid,” Ball wrote in an e mail after he looked at your photo.
Gary Lancaster, the proprietor of AK metal Fabricators in Alexandria, Va. (703-823-1661; ), also suggested Ball’s method. both mentioned they might use a pc-controlled water jet to reduce a replica form from steel plate, then add finishing details. the most time-ingesting part is writing the code and developing the machine. Ball spoke of he may make one half for roughly $a hundred and ten and a 2d for approximately $30. Lancaster included painting the metal in his estimate, which turned into about $275.
Given the entire options, and the problem of evaluating the condition from an image, you could are looking to send the constituents to at least one of these consultants or an identical company and ask for a hands-on assessment earlier than you commit to an answer.
