How to:  Deep Borders and Stippling Polymer80 PF940 V2 





Dave Modz: What's up everybody? Dave Modz Gun Fu. I got a killer video for you guys today. For all you do it, do it yourself guys at home. You guys are going to fucking love this video. In our last video we talked about easy borders and touched down on some stippling using...we did the borders using wood carving tools. Today I'm going to show you a new technique that I use or another technique that I use, and I think you guys are going to find this one really beneficial. Gun Fu is an authorized Polymer80 dealer. We recently got in our first batch of PF940v2s. Which is the full size 80% frames from Polymer80. What you’ll find in the kit is a jig to complete the frame, as well as the front and rear blocks retention, pins and the end mill and two drill bits for the holes you're going to need to drill for your trigger, your locking block and the bucket in the back. For those of you who are unfamiliar with the Polymer80 offerings, they’re are 80% complete frames, which allow you to do the sale and transfer of a frame, without the use of an FFL. Please make sure to check your local state laws, regarding the process required following completion of the frame to make sure that you're staying within the legal limits of the law.

Dave Modz: All right guys here is a breakdown of the tools you're going to need. We got the Dremel 4000 with the flex shaft. We have a stone grinding wheel, bit number 8193. Also bit number 8153, which is a small stone grinding wheel, I believe it's a 5/30 seconds. We've got a bit number 997, which is a conical grinding stone, this is going to be used for your tight corners and 511E, which are the buffering and abrasive wheels. I've also got my Wall Lenk wood burning kit with a medium pointed tip and for PPE, I'll be rocking out a 3M respirator mask, safety glasses and the gloves are optional. You can use them if you like. I don't. 


Now that we got all of that out of the way, let’s get into these borders. I typically like to start off with one of the smaller bits. I'm gonna be using the 8153 here and I'm gonna just use it to kind of work it into the corners, clean everything up and get those nice and tidied up before I hit it up with the large stone grinding wheel, the 8193. These wheels are really good. They don't hop a lot, give you a nice control in the corners and really do a good job of taking down that material at whatever pace you really want to take it down. If you want to cut quick use the leading edge, if not you can kind of just take your time and go back and forth with it. Anytime you are using these stone grinding wheels, you want to make sure that you get your leading edge parallel to whatever border you're cutting. You get that thing a little bit crooked and you're going to be making some crooked borders. So, take the time to make sure you got it lined up before you apply it to those borders.


Throughout the course of this video you guys are going to see me switching back and forth between these stone grinding wheels and these 511E buffing abrasive wheels. The purpose of these wheels is to remove the flash from around the borders and establish a clear line of sight. 


How you establish the aesthetics of your border work is really a matter of preference. In the case of the PF940v2, we had existing angles from the mag release relief and we kind of just worked with those angles and integrated them into our border.


Once I'm done roughing in all my borders using the larger grinding stones, I'm going to finish it off with the 997 bit, which is a small conical bit and this is going to allow me to get really nice and tight in those corners and I'll follow that up with the final flash removal, using the 511E abrasive wheels.


The pattern that I'm laying down on this frame is called the enhancing carry texture and it’s a no lift type stipple, wherein I basically keep the tip of the wood iron in contact with the polymer from large portions of the texture application. By drawing small S shapes and dragging it along the frame, I'm able to create a nice randomized texture that's going to be a pretty good tactile improvement, without being too uncomfortable to carry.


All right, guys that's a wrap on our deep borders and stippling for this Pf940v2 frame. I hope you guys will find the tools and techniques that I share with you here useful on your next stippling project. I've been using them on mine with increasing success. I'll make sure to leave some links for the equipment that we used here down in the description below. If you've got any questions or feedback, please feel free to post it in the comments and I'll get to it as soon as possible.
