After I have the basic shape I carve the angled indent in the back.
then make sure that it fits your Ruger. Then scribe the grip around your frame. Now I cut angle on the bottom of the grip using another jig and my band saw.
next I shape it with drum sander using 80 grit paper, this takes awhile and it can be painful when your fingers get sanded.
once you have it shaped the way you want it's time to hand sand. I start with 120 grit then 150 & 220.
next is the finish, which I mentioned is super glue. I just squeeze a little bit out and spread it with my finger. The stuff dries so fast that you can do part of it then let it dry and then do the rest. Do at least 2 full coats then sand with 220 until its smooth. You can see the low spots real easy they will be shiny. If you sand through the SG use a damp rag to tack the dust and spread some more glue. The great thing about Super glue is you can sand after 15 minutes. Polyurethane takes at least 24 hrs.
after 2 coats and sanded with 220.
then I wet sand using spray bottle I spray a little water and sand it with 400, 800 1200, 1500, & 2000grit. As you go the low spots become very visable, you want to fill those in early. Every time you recoat you have to sand from the beginning 220. After it's all sanded down to 2000 I use a little dab automotive polishing compound (3m perfect it 3 is what I use) on a sort cloth and will shine like the sun.
