my 1077 mod

[ZipSnipe]

Hello all, here,s my mod of my crosman 1077

[ZipSnipe]

The first pic is a rough paint drawing of what I am aiming for
the second pic is the cherry hardwood I am using for the stock
the third pic is the aluminum brake I made on my lathe and milling machine ( I have always liked that Barret .50 cal rifle brake they use so I made mine a lil similar)
4th pic is the brake on the gun, I think it adds a lil bad @@@ to the gun myself!!

[Donny]

thats down right cool

[ZipSnipe]

Thanx Donny

Here is a roughed out stock for it.

I thought the wood was cherry but it sure does smell like pine but its very hard so it might be Jaloby pine which is supposed to pretty hard.

Fun with epoxy!!   

If you look at the stock pictured above you may noticed that the handle is too close to where the trigger is, so I looked,debated and pondered what to do. So I cut the handle off as square as I could with the bandsaw and added a 1/2" block to bring the handle back.  This would also allow me to fill in that recess I cut into the handle.

So I got everything ready except a way to clamp it all once I doweled it and epoxied glued it.  Thus the fun began, I had mixed a lil extra so that once I glued the setup together I could fill the recess in with sawdust mixed with the epoxy. But not figuring before hand how to clamp everything was a big problem and by the time I got it clamped my cup of epoxy was smoking!!!!

A day of sanding and she is ready for the ebony stain I will be doing. Here's a pre stain look and For the adjustable stock, I just drilled and squared out two holes and then filled them with jb weld, 1/4-20 tapped it and used allen screws with press on adjustment knobs

[ZipSnipe]

Well here it is finished with stain and wipe on poly..     debating if I want to keep the wood look and just go for a satin black.

[Donny]

looks good bro, id go with a bedliner type finish or a  hammerd steel paint avail at homedepot to keep the tactical look

[ZipSnipe]

I might just do that Donny, that way I can sand it down more( I rushed it), get it nice and smooth.  The main thing for this mod is I have to keep cost at...free. Which means I will probably do the satin black that I already have. 

[Donny]

i think i may go buy one of these today

[ZipSnipe]

I love it !!  Cheap and bang for the buck if you compare specs with other rifles.  And easy to mod. 

If I do another stock I seen a kool router jig that a guy made for doing stocks on rifles.  I used my milling machine but the setup time takes awhile and the finish is not that good becuz my mill only goes to 1800 rpm(you need 5000+ rpm for a good finish)

Let me know if ya need any info on modding the stock

Wanted to give a cost breakdown

1077/scope/2 mags and extra clip with 5 co2 tubes    $80  (thanx Sniper)
can of satin black                                                     $4
allen screw and insert                                               $2
jb weld                                                                    $2

Total cost of mod                                                    $88
Total time  30+ hours plus I am going to sand down the stock and satin black it so probably another 3-6 hrs more

Wood I already had, metal I already had, thumb screws I was lucky and found those in my tool box  but they are only a couple bucks at the hardware store.

So not bad considering if I wanted to buy one of those Euro tactical guns would have set me back $500 plus

I want to build a type of bullpup design, compact, easy for back seat car fun

[ZipSnipe]

Yeah I started off that route(bullpup) and then I seen this gun in the attachment and that gun got me goin on this mod.

So my plan now for the bullpup mod will be the Crosman BBP77  breakbarrel pellet gun to be released in June of this year  http://www.crosman.com/airguns/pistol/BBP77

[ZipSnipe]

I like this for a bullpup design...its sweet!!!!

[Donny]

i went and bought one this afternoon, time for the fun to start, i really wanna try to increase the velocity at least to 700, i know its gonna be a challenge,  i down with the second one, it looks like an edgun matador

[ZipSnipe]

The main challenge(to bullpup a 1077) is you have to move the trigger forward and make a linkage.

I was thinking maybe running a linkage outside the stock or make the stock a lil wider and run inside. You just have to go around where the pellet cartridge goes in.

I seen a pic somewhere of a bullpup airgun where the guy ran his linkage outside the stock, I think it was stainless steel so it looked nice
