Sheppy Scotch Glue: The Glue for the Craftsman


Technical data

A high quality bone glue, manufactured from selected raw materials. It has a breaking strain far in excess of British Standard 745 requirements, and is recommended for antique restoration, piano actions, sports goods, high class furniture, chair frames, veneering, and any trade where a first class, long-lasting joint is necessary. The level of preservatives in this formulation keep the glue free from mould and bacteria for a long time in the glue pot. Its slower setting characteristics enable the glue to penetrate hard woods more deeply and provides a longer open time for intricate assembly work and veneering operations. Many of our customers claim that once used, they never return to Pearl glue.

For antique restoration and reproduction. While our Pearl glue is an excellent product, our Sheppy Scotch Glue has many advantages over it, providing stronger joints and ease of use.

  1. It is a ready prepared hot glue in jelly form, at the right concentration of glue to water, merely requiring heating to make it useable.
  2. Chemicals added to the high quality bone/skin glue lengthens the open time, allowing adequate time for assembly, very deep penetration of hard woods and, therefore, stronger joints and assists easier laying of veneers, particularly large areas.
  3. Unlike P.V.A's. which are not compatible with old hot glue. Sheppy Scotch glue is completely compatible with old glue. However it is advisable to clean off any surplus old glue that maybe weakened as a result of any past fracture of the joint.
  4. The lower melting point and longer open time of Sheppy Scotch glue enables the use of the glue in colder workshops and helps eliminate the possibility of poor joint strength due to the glue setting off before assembly. It can be advisable in extreme weather conditions to warm the wood before gluing and assembly, thus assisting the usual deep penetration of the adhesive.
  5. Sheppy Scotch glue is ideal for blocking out the carcase of a cabinet. It being merely necessary to apply the glue to the block and place the block to the vertical side of the cabinet, rubbing the block backwards and forwards gently until it resists movement, at this point the block remains where it has been placed without pinning . A perfect rubbed joint will have been made.
  6. Sheppy Scotch glue is strongly preserved against bacteria and fungal attack, unlike Pearl glue which is only mildly preserved. It is very unlikely to go putrid in the glue heating vessel and may be used for several days. It will, of course, require water to be added from time to time to compensate any loss through evaporation.
  7. Sheppy Scotch glue is completely compatible with Pearl Glue and, therefore, Pearl Glue can be added to it for very special application.

Sheppy Scotch glue was introduced in the very early 1920's to meet the requirements of the furniture industry in the days when it was perceived a slow setting glue had advantages over normal glue for veneering, assembly work and extraordinary joint strength. It was one of many similar products formulated by our competitors for the same purpose, however today, we are, we believe the sole manufacturer of this product. It is of the finest quality and it is easily available to the smaller user through a network of agents from whom it can be purchased in 1kg, 5kg & 12.5kg pails.

Our customers include Cabinet Manufacturers and restorers, Cricket Bat manufacturers for both the handle and to bond the spline, Piano Action manufacturers, Organ building and restoration and Violin/Viola repairers and manufactures.

DIRECTIONS FOR USE:

  • Place sufficient glue into a glue pot and warm it until the glue reaches the consistency of paint and flows freely. NEVER do more than warm the glue, it should never be so hot as to show steam rising from it.
  • Once warm, the heat can be turned off and the glue will remain liquid for some considerable time - dependent on the temperature of the workshop. .

DIRECTIONS FOR LAYING VENEERS BY HAND:

  • Sheppy Scotch enables veneers to be laid more quickly and with less effort.
  • The temperature of the glue is important, and it should be prepared and used as above.
  • Prepare the ground or base in the usual way. To make the veneers supple, coat them on both sides with glue and warm water (one brush full of water to one of glue). This should be brushed into the veneers for 10 minutes or so until they become supple. For harder woods and more curly veneers, it is advisable to apply more warm water with the brush and rub the solution in with the fingers until the veneers have become thoroughly supple.
  • Apply Sheppy Scotch to the ground and allow it to become somewhat tacky over the whole surface. The veneers should be applied and laid in the usual way, with the hammer working from the centre. If the glue should gel before this operation is completed, a moderately warm iron or a damp cloth dipped in hot water will render the glue liquid. If blisters immediately appear here and there, they will be drawn down as the veneers dry out and contract, and will not leave permanent blisters. If at these points and in particular parts near the edges of the veneered panels are not well laid, they can be put right next day - again with the aid of a moderately warm iron.
