have you had any time to shoot the new setup? once its said and done i'd like to know what the final components end up being and how much trouble you went through.
Yes I have fired it quite a bit. I had also banged a similar mounted base onto a steel anvil 1000 times and it never let go. I hit it pretty hard too....swagged the slide material but the part never separated from the slide rail.
What you need:
A red dot, a light one. The one I purchased is one of the least expensive of what are considered good ones...i.e., one that is well made and will hold zero. Shield SMSc (compact) with battery and mounting screws.
Small Tubes of JB Weld and a small tube of impact resistant Gorilla Glue.
A strip of aluminum, any kind. I used 1/8" x 1" x 48" from Lowes. Shortest piece they sold and cost $10. Bought a 1/16" piece today of same for $5. I will test that for a thinner and lighter mount. Let you know soon if it is strong enough for threading.
Strip of paint edging tape, something straight to screed the JBW, like a box cutter razor. Some emery paper 360 to 400 grit. One sheet is plenty. Use it for dressing the base, cleaning and removing construction scratches.
You will need to mark the outline of the red dot onto the aluminum base. A sharp pencil works fine. Also locate the mounting holes. You will need to drill holes precisely and thread them for the screws that come with the sight. I'll have to look back to see the size of the hole that needs to be drilled and the thread.
You will need to clean the top of the rail of all oil before installing the JBWeld. Bottom of the alum mount too before placing it on the monkey glue.
I also use a table belt sander to quickly shape the aluminum base. You could also file it. One of the little belt sanders has a 100 uses, doesn't cost much nor do the belts. Woodworking shops, Lowes, Home Depot....all have them. Should be $100 or less. You don't need something expensive for how this works....there is always flex in the belt. Belts can be purchased in a wide variety of grits. 1917
