Crane Lab · EOT
The hoist motor turns the rope drum. Wire rope raises the hook block and the load.
The trolley runs along the main girder and carries the hoist across the span.
End carriages drive the whole bridge along the runway rails, the full length of the bay.

Machines in Motion
Four of his machines, drawn and running live in your browser. Hover a panel to look closer.
Hydraulic trolleys load each slab onto the roller table. Twelve heads grind and polish it as it passes, from coarse to mirror finish, and the unloading trolley stacks it at the other end.
A flywheel and connecting rod drive a frame of parallel steel blades back and forth. The frame lowers a little with every stroke until the block is cut into slabs.
The gantry runs on its own legs along the yard track. It picks rough blocks from the stack and feeds them to the cutting machines.
The bridge moves on X, the head moves on Y, and the blade tilts on A and C. It follows the CAD path to cut a countertop with a sink opening in one program.

Plant Layouts · 2D CAD
The final layout acts as the master plan for the plant. It sets which job comes first: crane tracks and borewell, then machine foundations, then the polishing lines and offices.
Plot length and width, north arrow, road side and truck entry, mapped before anything else.
Full machine dimensions, X/Y axis travel, Z-axis height, blade size, loading space and maintenance clearance.
Raw block → cutting → finishing → dispatch, with short, safe paths for slabs, cranes and forklifts.
Gantry and EOT runways, column positions, anchor bolts and foundation sizes.
Water treatment, slurry tank, filter press, compressor and electrical room, oriented to Vastu where the client asks for it.
Room directions, plot measurement, doors and windows, furniture and the open-area split, drawn for homes as well as factories.

Residential Project · Shree Kutumb
A complete house design on a 183 sq yd plot: the site plan, a dimensioned 2D CAD layout, rendered plans of both floors and the front elevation of the finished two-storey home.
The client plot located on the colony map, with roads, khasra numbers and plot area.
Room-by-room dimensions, walls, doors, windows, the underground water tank and the staircase.
Furnished, coloured plans of both floors so the family can see the home before it is built.
The finished front: wood-clad balcony, glass stair tower, louvres and a covered car porch.

Where the Stone Ends Up
Temples and idols, kitchens and vanities, staircases, interiors and export yards. The machines make every one of these possible.
