Keg Blanks and Keg Tenon Turning
Keg Blanks: Material with tenon turned (one can add tone channel drilling, back boring, and o-ring groves for an additional cost)
Looking for keg (insert) blanks? We can turn them for you from your 4' lengths of cast acrylic rod or other round rod stock.
Minimum run/batch size: THREE 4-foot sticks or 12 feet in minimum of 2-foot long pieces completely cut into keg blanks.
We will cut and turn your acrylic rods into blanks to your specifications. This does not include any shaping of the keg, only turning the tenon (dowel like portion or shank) of the blank. Tolerances on length are +/- .030" and .002" on the diameter of the tenon. We generally aim for .001" oversize from the specified dimension on acrylic material to allow for sanding and polishing. Non-sanded materials (usually Delrin/Acetal) we aim for .001" - .002" undersize of the specified dimension. You may request that the under/oversize method not be used on your blanks. The surface finish left from the machining process generally only requires light sanding with ≈600 grit sand paper and then buffed or flame polished.
Pricing varies by length and diameter of the tenon of your blank, but is generally $3.00 - $4.00 per part with a minimum of THREE 4' sticks cut completely in to blanks (appx 11-12 parts per stick).
Please Note: Tenons over 2.100" in length (not entire part length - just the turned tenon) may result in added costs or may not be possible without severe tool chatter. Keeping your tenon at 2.100" or shorter is STRONGLY SUGGESTED! Longer is certainly possible, but can be problematic, or require a different machine setup that can add more cost and removes the possibility of also drilling the tone channel in the single operation.
We try and avoid turning pre cut blanks due to the added cost to the customer. But if you require pre cut blanks have the tenons cut, you can expect the price to be 1.5x to 2x the normal per part cost of running a full stick.
Tone Channel drilling is available. Please see "Small Bore Drilling" for more information.
Pricing may change depending on material and demensions requested and you will be quoted prior to any machining taking place.
