Re: E. Cohen, Dakota Scimitar 260 Medium Tac Build
Thanks!
Finished up the floor metal. Here's the inlet work on the stock and piece as its being fitted. Still a little ways to go yet in the back to get everything caught up.

Man, seriously crazed. I'm loving it.

Me too; one of my reasons for going with Chad. I wanted a true custom piece, and one that was as much art as a precision tool. Very different than just bolting in parts.
I've greatly enjoyed being part of the process and am really looking forward to getting it home.
All in all a neat experience

Back to our little pet project.
November was made of bitch. Just sucked as I all did all month was fix shit and hemorrhage money.
December is proving much more lucrative. A good thing.
BACK TO WORK!
So, the 7mm-300WM we did recently proved a nice platform for testing out the cheek hardware. So nice that I've decided to make another for this gun. I've changed a couple little things, but essentially its the same.
Here's the 1st op:
Just finished it, bout to buzz it off with a miter saw.
Woo hoo!

Re: E. Cohen, Dakota Scimitar 260 Medium Tac Build
Never take it for granted, just thankful the ability to do this kind of stuff.
Thanks for the kind words.
Onto the buttplate assy. Using one of my mentors for inspiration (The world renowned ALEX SITMAN (supah badass guy)) I'm looking at his 3axis buttplate assy and dissecting it, trimming off the "fat" so that it's more appropriate for a tactical gun.
Here's the 1st step: Sorting out the profile of the Manner's T5 A stock. Using a tracing made directly from the stock I photograph it and import the photo into the puter. From here its a matter of cleaning up the lines/arcs and scaling the image to the proper size.
Now onto making the wigit work. . .
More to come.

Re: E. Cohen, Dakota Scimitar 260 Medium Tac Build
Here's the baseplate all finished up:
Again, having a "long leash" helps with projects like this as it allows/encourages the creativity to come out. The plan here is to emulate the one that Alex Sitman makes, but to put a twist on it so that were more aligned with the "tactical" theme.
Sooo, instead of making an additional piece that attaches to the outside of the base plate (containing the clamp mechanism for the pin) were going to put it inside the stock for a simpler/cleaner appearance and shed some weight off the bugger.
Here's the base plate. I had some fun with it by overlaying our proprietary "holographic" camo pattern onto the part and engraving it into the material. Subtle, but kinda neat.
My "fixture" was a scrap/setup piece of AL used earlier this year to proof out an engraving program I used while making award plaques for the ordnance crews at Ellsworth, AFB.
Machined blank fully profiled and qualified:
Camo pattern from a random stencil:
Engraving:
Final piece:
Looks "fuzzy" from me brushing it with scotchbrite afterward. Once its blasted/coated it'll clean up nice.

Re: E. Cohen, Dakota Scimitar 260 Medium Tac Build
More progress.
Clamps are done as is the vertical adjustment base for the recoil pad. One piece left to make.
Woo Hoo, all that's left is inletting the stock for this chit, some sanding/fluff/buff, and were ready to squirt paint!

Chad,
I like the slimmed down look of that butt plate. Always liked the Sitman/Masterclass unit over the Tubb plate but felt both were too bulky for what they are asked to do. Yours looks like a very nice compromise.

Re: E. Cohen, Dakota Scimitar 260 Medium Tac Build
The engraved camo pattern is pretty bad ass. I haven't seen that before. Keep those pics coming, this build is definitely "outside the box". Well done Chad.

John,
Alex and I talked it over yesterday in fact. I do like his stuff much more than other versions and for a target rifle it is a very appropriate piece I think.
Tactical stuff however kinda demands a more simplistic and compact approach. Least I think it does. Its for these reasons I decided to tackle this. So far its come out well. The base plate is now fitted to the stock. Just waiting on the brass pillars to setup. (bedded/glued in)
I'm onto fitting the cheek hardware now. I whipped up a neat looking boss for the buttplate LOP adjustment/pinch screws. I'm chomping at the bit for this epoxy to harden so that I can fit it up and get a "real" picture of how this thing is going to end up. So far I'm diggin it.
I was able to shave off a solid 7oz over the MC piece. I could swiss cheese it a bit more and get some more weight out of it, but I think I'm going to leave it. At some point it gets a bit silly. -That and the costs can get carried away as well. It is just a buttplate. .
Later!

Re: E. Cohen, Dakota Scimitar 260 Medium Tac Build
A few updates to wrap up the day.
The morning started with getting the backing plate mounted up along with the internal hardware. The horizontal mill I acquired this summer makes this a snap. No complicated fixtures anymore.
Got the ferrules installed and let the stock sit for a few hours to allow the epoxy to cure before the trial assembly.
This allowed me some time to make a few other wigits for this gun. I like the look of beveled bushings where accy parts get snugged, clamped, adjusted, whatever. So, I devoted some time to whipping up a handful for the various pieces.
First was for the buttplate LOP adjustment.
Next, the cheek hardware:
Finally, I bushed the bottom holes where the cheek pins run. I decided to poke these all the way through because it allows one to position the side/side of the cheek hardware without removing it from the stock. This way you can lock it down and know it didn't move. Might be kinda silly, but since were turning this thing into a hardware store, what the hell. . .
I also finalized the pin base clamping arrangement. I silver soldered in the screws so that they never back out/vibrate loose.
Were getting very, very close to being able to put this bugger together to check all the particulars.
Left to do:
Make/install the brake
attach the recoil pad to the buttplate assy
drill/tap the buttplate vertical set screw adjustment
fit guard screws
inlet the cheek piece (this particular piece was already inletted so I filled it up today so that I can machine it to fit our unit)
Make the scope base
trial assembly
Test fire
Tear down, fluff/buff
Paint/finishing.
Could possibly have it in primer tomorrow afternoon. I plan to work as next week is a full plate.
Eric, it's coming along well and I hope you like what you see. As always, if something doesn't sit right, just give me a call.
A good day, got lots of chit done.

Thanks again for sharing this with all of us. Still trying to wrap my head around the Scimitar design.

Fitting the recoil pad this am.
Couple things to do yet:
Attach/grind the recoil pad
Thread/chamber the 2nd barrel (Ordered Monday, should be here by Friday)
One last trial assembly
Engrave both barrels
Paint.
Will have it in primer/base color by COB today. Pics to follow.

Re: E. Cohen, Dakota Scimitar 260 Medium Tac Build
She's in primer.
Shot it this am and let it flash out. Filled in the boogers, sanded again, and primed for good in preparation for the base coat.
It's drying now. In a few minutes I'll scotchbrite it and we'll have some Desert sand on this bugger.

I bought here a 1981 Honda Express this summer and if its nice out you can't get her off the damn thing.
This winter we'll be tearing it down and restoring it. If she lets me I'm going to build a water cooled big bore cylinder for it, bump the compression a bit, find a tuned pipe I can "Frankenpipe" onto it, and maybe put a 5-10hp shot of silly gas to boot. I've got a 19mm Delordo carb for it already.
