In my other crafting … I have precision tipped bottles for glue work. Yesterday I searched online to find something for wood glue. I came across the GlueBot. Rockler’s and Menards carry them, or you can order online from Amazon or FastCap.
When you squeeze the large portion of the bottle it bottom feeds to the small cylinder. When you stop squeezing, it sucks the glue away from the tip … which means the tip is cleared! There are videos on the link below to show how it works.
They come with a blade tip and a thin glue line tip. I switched mine to the Yorker (thin glue line tip). Excited to use it later today.
