Sealey Vertical Milling & Drilling Machine

Typical of the generic Taiwanese "Mill/Drill" as made from the early 1970s, the Sealey had nothing special to commend it - other than the use of metal instead of plastic handles together with the general usefulness and low price of the type. Lacking the bevel-gear driven elevation to the head that maintained alignment throughout the lift (as as found for example on the superior Naerok and Draper versions) the head on the Sealey was lifted by a crank handle whose gear ran directly against a rack free to rotate between its top and bottom holders--the result being that, once unclamped and moved up or down, the head was free to swing around the column and so loose its alignment.
In addition to the elevating head, the quill, which held a No. 3 Morse taper spindle, could be moved by either a handwheel fine-feed control (working through worm-and-wheel gearing with each division on the micrometer dial being 0.025 mm)) or by a 3-spoke, quick-action capstan handle. Power came from a rear-mounted 3/4 h.p. motor (the type generally having between 1/2 and 1.5 h.p.) with drive by an "A" section V-belt to an intermediate, self-aligning, 4-step jockey pulley and then to a 4-step front pulley, the arrangement giving 12 speeds that spanned a most useful 200 to 2500 r.p.m. - a range typical for the species.
Although inexpensive, of relatively crude construction and with a less-than-perfect cosmetic finish, this type of mill/drill is a most useful addition to any workshop. Able to mill to tolerable accuracy with either large or small cutters, it becomes most handy when used as a coordinate drill - the vice being bolted securely to the table and the slides then manoeuvred so as to bring the workpiece exactly into place..
