Set up for individual restorers and hobbyists, and for restoration shops and classic-car builders who need small parts (hardware, brackets, covers, castings) batched out and returned clean. Phoenix Valley only — drop-off by appointment or scheduled pickup for shops.

Will it fit?

Interior 33in × 14.5in × 16in. Bigger than most people think.

Practical max part is roughly 30in long × 12in wide × 13in tall so media can flow around it. Long slender pieces — tube sections, trim, shafts, rails — up to ~30in run whole, no cutting. No bumpers, wheels, or full body panels — those exceed the width/depth even when they're under 33in long. No chrome plating, re-chroming, or buffing-wheel mirror work either — for those I'll point you to a local shop.

The line: a 5 ft³ Oceanic Innovations Whisper Shake 5 vibratory system — media matched to your part.

The tumbler interior is 33in long × 14.5in wide × 16in deep (5 ft³). Practical max is roughly 30in × 12in × 13in so media can flow around the part. Long slender pieces — tube, trim, shafts, rails — up to ~30in run whole, no cutting. Send a photo with rough dimensions and I'll confirm before you ship.
Send 3–5 photos from different angles with a rough size reference. We confirm the part fits the tumbler, pick media, and quote the lot — usually within a business day.
