Besides Water, A safe Resin Cutting Technique
Posted by Tanker-Builder on Thursday, December 29, 2022 8:35 AM


       I just replied to a thread on handling Resin. Then I remembered I didn't call to attention a method I use for seperating the resin part from it's pour block. I am sure, being Modelers, you all are aware of the numerous cutting tools out there, Right? Well here's one I forgot. When I get resin parts, Mostly in Plane building, I do this. Are ya'll familiar with Glad Bags?

       Well they make a few under a different name, I don't remember that. But, they come in a nice five gallon clear size too! Now you take one of these bags and get ready to use the tool I am going to talk about. Micro, P.E. Stainless saws!! That's right! They are all kinds of weird shapes and they come both with and without handles(You can buy the handles separate.) Some are so thin they look to weak to do anything. Wrong!

       Using a light touch I cut a car door opening, in styrene! The saw was so thin I had to work close under a light. BUT, using it and  an EXTREMELY LIGHT touch, It cut through like going through Butter! It was thin enough it left material on each side of the molded door line so sanding to perfection was easier. These little saws cut resin easily and again using a light touch, cut closer to the part. Do you know or remember Paisley pattern Shirts? Some of the saws are shaped like the shapes on that and in the Paisley patterns.

       There are straight wide and skinny ones too. The ones I like best are Those with a gentle curve ending in a sharp point that also has teeth on the other side( Under a magnifier) the teeth go all the way around the tip! Great for cutting a small area and creating entry holes to remove the panels getting replaced with Resin!

What I find with those saws is that they have very littie tooth offset and create a lot of friction.  This creates a lot of heat, whether cutting polyurethane or styrene.  I always have to lubricate with water when using them, or else go maddeningly slow.

Hi Missileman2;

       Yeah, I forgot to tell everyone that it can be maddeningly slow. But I assure you slow is better here. Nice clean close cuts. Oh, and under a loupe, the brand I have has a reasonable offset for their size and type!

      No, those are Not the blades I was referring to.I don't remember the brand name ,but they come i think, if i remember right six or eight to a bluster pak. They are all different shapes and when you see them your first reaction will be"What the heck can you use those things for". 

      I find the paisley shaped ones great for most stuff. Cutting with the rounded wide end and then after a breakthrough taking the pointed end and finishing the cut out!
