Stephen has designed a glue dispensing machine using an old pressure spray bottle. He made an adaptor using thermal plastic (you can soften this plastic in hot water and mould it into anything you like) with a high pressure compressed air connector. We then connected a length of garden hose to the outlet and a quarter turn valve to control the flow. With further moulded plastic modules shaped into a broad nozzle to the width of various timber (38mm is the most common) and drill a couple of little holes to allow the glue to come out in a constant stream!
It is working in tests but we haven’t tried it for real yet!!
