An adjustable support carries a workpiece in a manner that allows convenient welding. An enclosure having opposed half-round ends and a rounded half cylinder body defines an insulated workpiece cavity. The enclosure supports a hinged cover having a frame within which slides first and second sliding doors which allow an opening of variable size and location to be formed for access to the workpiece cavity. A frame provides a base from which extend left and right forks which are pivotally attached to opposed middle portions of the enclosure. A locking pivot allows the angle between the forks and the enclosure to be adjusted and fixed as desired. A support insert, extending from the base of the frame, may be attached to a support mounted in a work area, heating area or cooling area. A locking pivot allows the angle between the support insert and the enclosure to be adjusted and fixed as desired. A restraint assembly, carried within the enclosure, provides one or more arms which may be adjusted to hold the workpiece in place.
