Transporting a bombard: windlass, cart and timber joints
Hauling and emplacing a bombard - 24 men at the windlass, oak planks, uphill props, and timber and iron sizes
The verso collects small mechanical sketches concerned with moving and mounting a bombard. Notes record that 24 men worked the windlass (argano) and six at the two uprights, that oak planks must be set under the bombard once it rests on the cart, and that when oxen haul uphill the cart needs a prop behind it. Further captions give the dimensions of timber axles or beams (three fingers thick) and of an iron fitting (an inch and a half). Various wooden and metal joints are drawn around the sheet.

Setting the bombard on its cart
When the bombard rests on the plane of the cart, oak planks are to be placed beneath it - a note on safely bedding the heavy gun for transport.
Windlass worked by 24 men
A windlass (argano) is drawn at the upper left; the note records that 24 men were at the windlass and six at the two uprights, indicating the manpower needed to move the load.
Propping the cart on an uphill haul
When the oxen pull uphill, the cart requires a support behind it to keep it from running back - a provision for hauling the heavy load up a slope.
Timber and iron joints and sizes
Captions note wooden axles or beams three fingers thick and an iron fitting an inch and a half thick, beside drawings of wooden joints and a metal junction.
