McNeela Instruments is not just an traditional irish instruments but an entire Irish Music experience that supplies a whole list of music instruments you will recognise that are synonymous with traditional irish music or or trad music as it is known locally. Tools: Introduction: Concertinas and Irish flutes are usually a very good investment, even the beginner concertinas for sale generally improve with age and the more they are used the more the reeds open up. Repairing concertinas and accordions: The Gauge Action Plate: Procedure: 2. Remove the old pad, either leaving the leather arm end bead still attached to the action arm, or by ripping that off as well. This is a fairly brutal process that involves the use of pliers. I found it best to work on alternate pads at a time. Thus I was able to use the positioning of the adjacent pads to help with the centring and positioning of the new pads being fitted (relative to the adjacent pads). I also remove no more than three or four pads at a time. This reduces the numbers of keys and levers that are flopping about. I no longer try to preserve the arm end beads; it is not worth the effort to reclaim them. 3. Examine the pad hole and surrounding scribed circle, looking for cracking, splintering, etc.. If there is damage that will cause a potential airway or make the bedding of the pad difficult, then mix a minute quantity of plastic wood. Force the plastic wood into the area of damage and wipe off any excess. Immediately, before the plastic wood has started to harden, stick Sellotape over the hole and surrounding area and then press smooth. Once the plastic wood has fully cured, peel off the Sellotape and a smooth finish will be revealed. Lightly sand the area to clean the pad seat area and blend the repair. Ensure that the corner of the hole that the pad seats against i5 lightly sanded to remove any surplus plastic wood to form a clean arris or sharp edge between the hole and the pad seating face. With the craft knife or sharp point clean out the scribed groove round the pad hole. Small piece of card or stiff paper, 6 mm. wide and 25 mm. long, to act as a spacing shim between valves and chamber sides. I have been told that some people use masking tape. 3. Pull off the valves from the wood taking care not to catch, loosen, or damage the valve pins that stick out from the chamber walls over the larger valves. Using the chisel and knife scrape off any old leather and glue remains from the wood. Work along the grain, do not dig in and do be sure that you leave the wood that the valve is to close against as smooth and fiat as possible. 5. Fit the valves, one at a time, offering them into position with the taper towards the pan centre. The shiny side of the leather must be up and fleece side onto the wood. Trim the valve with scissors, but only if absolutely necessary. Ensure that it will not foul the chamber side or go near the adjacent reed. When happy with the position, mark the valve's outer end position on to the wood with a faint pencil line. Trimming can be used to ensure the valve does not catch on the chamber wall, and occasionally I find a valve that needs to rest on part of the reed frame, but the tongue must be clear. Trim as needed. 4. Using a small dab of I'VA glue, fix the reinforcing disc into the centre of the backing side of the pad. That is the card side, not the leather face of the pad. 5. If you are reclaiming the arm end beads, then using the pliers squeeze the leather bead to remove as much of the old glue and debris as possible. Use rough sand paper on the underside of the bead to preh r it for fixing to the new pad. Either re-fit the old bead, or screw a new one into place on the threaded end re the arm. 6. Slide the pad with its attached disc under the bead and centralise the pad over the hole and scribing Adjust the bead to rest as close to the centre of the disc as possible. Set the key to vertical and use the bending tool to bend the arm laterally and vertically to get the bead positioned correctly and to ensure that the key conforms to the height gauge with a new pad fitted. Gently depress the key and put a dab of EVA under the bead and ease the bead onto the pad without upsetting the pad or key Adjustment should be made by bending the arm at the pad side of the pivot, and before the pad is glued. Of course it depends on your will to learn but also be assured to know that you normally should be able to sell it on and get a large proportion of your money back and we also do trade in's when you want to upgrade to a more advanced instrument. 9. If the 3 mm. key travel causes the key pegs to lift out of the peg holes, then reduce the 3 mm. by 0.25 mm., and if necessary re-set all the keys to be of a consistent height. 11. Leave the assembly at least a week or more before expecting the beading process to sty,. to form effective seals. Missing or lost valve pins can be made by using the pointed end from a sewing type pin (not a needle): cut 't to length using the side cutters on a pair of pliers. Be careful because they can fly out and eyes are at risk NOTE: Re-valving can have a minute effect on the tuning of the concertina as the chamber air volumes at be affected. However this should not be sufficient to upset most players, despite what the profess. 10114 would have us believe! If you are to re-tune your instrument then do re-valve first. The Fads are the 'stoppers' that are moved by the action to allow air to pass through to the chamber and hence reed assemblies. With age they can become hard and the seal may be lost. A symptom is a reed permanently sounding (possibly faintly) in the background. The condition is then ascertained by inspection. Fad leakage will also result in bellows 'creep'. Another common problem is that the padding that supports the soft leather sealing face gets hard and thin. When the key is depressed then allowed to spring back, the pad 'clicks' loudly. |
