Credit given to web56n at Tech-Mods I’ve seen many people ask what the best way to glue acrylic or plexi, was, so I decided to write up this little guide to help show the easy way to achieve nice clear and strong factory results. With this procedure I can not stress how important it is to take caution when using this glue. While performing this please wear Safety Glasses because 15 minutes of aggravation while doing this is better than a life of not being able to see. Here are a few things you will need: If you want a perfect factory look in joints use a product from Weld-on number 4, the can might cost you about $4 or $5 but it will also give you enough to last a life time or at least a really large project. The best way to apply this clear water-like glue is to find yourself a disposable syringe from a medical supply outlet or a drug store. If possible get the finest one you can get, all because it is unbelievable on how little of this glue is needed and if you apply to much it will just mess up the final look of your job. If you plan on doing more than one joint you can use the same syringe at the same time. If you plan on doing more joints at a later date I would suggest picking up a few of these little guys because after about an hour the syringe will dry up and will not work. Have some fine grit sandpaper to quickly scratch the surface of the piece you choose to adhere, only one side or piece needs scratching. If you are butting the joint so you can see the edge after you might want to only prepare the piece you are gluing and not the larger piece. I will show you a simple fix on a drive bay from an acrylic case; this is just to give you an idea on how to do the gluing. You can experiment on other things to make literally anything you wish once you have the procedure down pat. Set your two pieces in place and have either a steady hand or something with just enough to keep the pieces in place and slowly inject the weld-on glue right into the joint on both sides of the piece. I will mention once again you will need next to no amount of glue for a joint. It will take only minutes for the glue to completely dry, making the newly glued joint as strong as before or as strong as ever. If you have too much glue applied it can become messy, as you can see the scratches are filled evenly with the water-like glue and will dry clear. As I said before please take caution when using this glue, have safety glasses on and properly dispose of the used syringe when you are complete. Good luck and hopefully you can come up with vast amounts of creations in your modding travels.
