PE on a budget - without going to a model branded product
Cut your PE on a piece of bathroom tile I had leftovers when we built the house, but 4x4 tile is available cheaply at the box store Cutting mats are soft and will allow the PE to deform before cutting
Cut your PE with a #10 round xacto blade Cut in a rocking motion Useing a #11 blade, the point will snap first use Bespoke PE cutting shears are $$
Get a couple of single edge razor blades to use to bend the parts. Hold the part down at the bend with one blade. Slide the other under the part so the blades oppose each other. Raise the lower blade in a hinge motion.
Scraper blades 4x0.5 from box store will be similar, but longer. Longer yet are stainless rules
Once again go to the box store and pick up a set of drill bits. Wrap the PE around the drill shank to form round bends. You may have to go a size or two smaller to account for spring-back.
Instead of using a PE-specific PVA glue brand named for a certain swamp reptile, pick up a bottle of Aleenes Tacky Glue at the local craft store. It grabs quick, yet allows time to reposition the part. Cleans up with water.
