John Drummond of Milnab (d. c.1550) was a 16th-century Scottish carpenter in charge of the woodwork of the palaces, castles and guns of James IV of Scotland and James V of Scotland. John Drummond was the second son of James Drummond of Auchterader. A family history narrates that in 1521, John Drummond was given the lands and mill of Milnab in Strathearn, and the royal charter described him in Latin as; "Machinarum bellicarum ejaculator et carpentarius noster," - "keeper of the throwing machines of war and our carpenter." The gift was from the young king with the advice of his mother Margaret Tudor. Royal buildings A Drummond family history attributed to him the fine timber work at Stirling Castle including the ceiling medallions known as the "Stirling Heads" and the roof of Drummond Castle set up in 1493. Records of the royal exchequer of Scotland outline the career of the Master Wright with more certainty. John Drummond was first recorded as a wright (carpenter) in 1506. In December 1508 James IV gave him a pension of £10 from the customs of Edinburgh, which he later surrendered for the gift of the mill of Milnab. James V made him Principal Master Wright on 8 June 1532. In Spring 1538 he went to Tantallon Castle and Dunbar Castle with William Hill, the master-smith, to oversee repair works. John Drummond and his two workmen went to France in 1538 on the ships that brought the king's bride Mary of Guise to Scotland. In 1541 he built a part of the Register House in Edinburgh Castle and also worked at the castle of Crawfordjohn which had been forfeited to the crown by James Hamilton of Finnart. In March 1540 he organised repairs and re-slating of the roof of the great hall of Edinburgh Castle. In December 1541 he made an organ-loft at Edinburgh Castle and it was carried in carts down to Holyroodhouse to be installed for Christmas. Moving and mounting the royal artillery In 1515, John took the guns off two warships, the James and Margaret, at Dumbarton, which had been returned from France by the Duke of Albany, and took the cannon to Edinburgh overland via Glasgow. John was often based at Edinburgh Castle where carpenters and ironworkers maintained the royal artillery. He directed the transport of these heavy guns. In 1528 he and another gunner, Robert Borthwick, advised the Master of
