Here's my parts list, build steps, and a few photos. This mount is for a 1010 rail, I have a second mount (very similar) for 1/4 rod. The jawstand is perfect for this combination as it takes only seconds to switch from rail to rod.
PARTS LIST:
QTY ITEM
1 1010 Rail. Recommend minimum of 72 inches.
2 1010 corner braces. Used to attach the rail to the 2x4 “head”.
1 Package of 1010 2-screw bolt assemblies. You will have enough with a few spares. Used to attach the rail to the corner braces attached to the 2x4 head. Also used to attach the blast deflector.
1 Rockwell Jaw Stand
1 4” corner bracket. This needs some bending, cutting, filing to create the blast plate attachment.
1 Aluminum or other metal blast plate. Whatever you have that is sturdy and will stand up to the blast. Roughly 6 - 8” in diameter should do.
2 Machine screws with washers and bolts to attach the blast plate to the 4” corner bracket. Maybe half inch long.
3 1” conduit clamps. These take a little bending to create the hooks that support the 2x4 head. I think they come in packs of 8.
1 2x4 24 inches long.
2 1” wide strips of Luan or other thin plywood. Some old fin stock would probably work. Something to take up some of the slack in the Jaw Stand for a tighter grip.
12 About a dozen wood screws or drywall screws to attach angle brackets, clamps, and Luan to the 2x4 head. 1” to 1.5” would suffice.
3 8 or 10 inch spike … giant nails … to anchor the Jaw Stand. There are holes in the feet.
Misc: I added some thin weather stripping and tape to the conduit clamps to give them a bit of cushion in the Jaw Stand. If you are worried about protecting the wood … some sort of weather treatment. Since I only fly on nice days … and it sits in my garage when not in use … I didn’t bother.
Basic assembly … see the attached photos … really pretty easy. If you can build a rocket … this will be a piece of cake and take maybe a couple hours … tops.
1. Get the wood bits cut to size and sand the rough edges. Weather treat and let dry if you want to do that.
2. Attach the two 1010 corner braces to your rail with the 2-screw assemblies and then fit that to the 2x4 to ensure it runs true up the center of the 2x4. Mark the drill points for the wood/drywall screws.
3. Drill small pilot holes for the 1010 corner braces … this will help ensure you keep the rail properly aligned. Then attach the 1010 corner braces.
4. Use a vise, hammer and pliers to open up the 1” conduit clamps for the hooks that will help support the 2x4 in the Jaw Stand.
5. Attach the weather stripping and tape to the conduit clamps if you choose to do this. Not really needed, but it does make it easier to get a snug fit.
6. Attach the conduit clamps to the 2x4 so that they align with the three tubes at the back of the jaw. You can attach the top one and then hang it in the jaw to mark the spots for the other two.
7. Attach the Luan/thin plywood strips to the sides of the 2x4. Again, this is just to take up some of the slack and create a more snug fit in the jaw.
8. Cut your metal deflector plate to desired size.
9. Bend and cut the 4” corner bracket to the desired shape for the blast plate attachment. File any sharp edges. For mine, I bend the bracket to add a stand-off about 2.5 inches above the blast plate and I have the plate at a rough 45 degree angle.
10. Drill holes in the blast plate for the machine screw attachment.
11. Attach one of the 1010 2-screw bolt assemblies to the part of the blast plate bracket that will be mounted to the 1010 rail. Get the screw plate aligned with the bracket, snug it down and then mark the drill hole for the other screw. The holes most likely are not centered. If you want to get slick, you can drill two brand new holes dead center in the bracket. I didn’t bother … it’s only slightly off-center and the blast plate is certainly big enough that 1/16th of an inch won’t matter.
12. For step 11 … since the 4” corner brace isn’t as thick as the 1010 rail you may find that the screws are just a tad too long. I just added a couple washers to take up some slack.
13. That should do it … ready to put all the pieces together. When you break it down, just loosen the screws enough to slide the rail off the 2x4 head and to slide the blast plate bracket off the rail … leave the screws and back-plates attached to the 1010 corner braces and the blast plate bracket. Everything should easily slide together.
