G.T.S/T barrels report...
 

Hi to all, I just today finished up assembling the G.T. Sport Target barrels that I had orders for... But, in the long elapsed time to complete, and also the on-going drum repair, I made an error in who I was making one of the barrels for? I made a 2.750" for Don V. and a 6.000" barrel for Richard H. and another 6.000" for Ed T. and, I also made a 4" complete with receiver and toggle train for...?????? I had thought Ron Wood, but turns out I was in error.. so If anyone had what I just described above on order, please let me know ASAP! ....;).... If no-one claims it by the end of the month, I will offer it for sale .... Anyway, it's now off to the range for function testing and accuracy! I'm excited.. wish I could shoot better!....:)... best to all, til...lat'r....GT.....:cheers:

GT,
that is good news. Let us know how they shoot for sure!

What style is the 4"? heavy bbl? slab side?

I already have a 4 inch and love it (HB) and really looking forward to the 6 inch HB design :)

... ;) ...

A BIG 10-4 on that Sheepherder!

barrel pics!
 

Hi to all, I have just upgraded to windows 10 and for some reason, I can't get pictures to load?.. But, I have sent Dons Baby top half, a 9mm with a 2.750" barrel out to him yesterday! He will have it early next week, but has to fit and profile the custom Mauser K98k style front sight blade first! Perhaps he will take some pictures? It is a striking assembly with the scalloped toggles done by Rich for him, and the slab barrel, one of as kind for sure... :thumbup:....
Richard H's unit is nearly ready for the range as I have to do the same front sight work as well... Ed T's unit is ready except his receiver needs some straightening, as it works fine loose of the frame, but tightens up when installed...:jumper:... So, off to the frame straightening jig we go!.....:jumper:..... I have the 4" GTS/T top half complete with an original Luger front sight ready to go?... But have not as of yet found an owner for that hound??.... It's 1K total shipped.... open to first come first serve.. I'll release it for sure on the 25th if the original order person doesn't step up by then.... But if you want it, speak up now, as there will probably be no more this year.... Best to all, til....lat'r.....GT.....:thumbup:

GT,
thanks for the update. You can be sure I'll do photos and post.

What is the barrel profile of the 4" without owner?

what Ollie said was it is the same profile as mine, since that is the set up they decided on - took my suggestions, their suggestions and just made a design...

My apologies GT I tried to share the previous pictures and it popped them on top, I will fix it if I can get my computer acting okay.

You can send me any pictures and I'll post. Whats with my receivers wanting to be twisted?

"Whats with my receivers wanting to be twisted?"

Usually results from use of pipe wrenches too large for job at hand!:evilgrin:

GTS/T barrel info.
 

Hi to all! Hi Don, the latest final design of barrels that we just ran are nearly identical to the prototype that Ed pictured above, with the following changes, first of all, we radiused the muzzle to break the sharp edge on the outer most edge, and we increased the overall diameter to match that of an original Luger barrel flange dia. for two reasons, one to add aesthetically to the over all look, and two, to add a little defining material between the slab sides and the front sight relief?... Or at least that was the goal! .... Don, the four inch offering is exactly like your baby except longer, same with the 6.000" as well... they will all be the same from here on out as small changes are a lot more work and fixture time then it would seem... The one I now have extra is mounted in a very nice 1920 commercial receiver with DWM toggle train, all the small parts, and Luger front sight! It is exactly what I'm trying to accomplish for a G.T.S/T shooter offering! And any time I get a 1920 commercial top end, that's probably how it's going to end up!:thumbup:

Ed. the bad news on your receiver is, sometime since man walked on two feet, someone tried to remove the receiver by using a bar between the forks and spread it slightly right behind the chamber.. then to get it to fit, they squeezed it some right behind that!....:eek:... giving both, now bent forks, a coke bottle effect when all is put together... it, grabs, stops the breechblock from the middle back?... Good news, is, I can straighten it out... just take a couple of hours on the bench in the receiver straightening fixture.... I will straighten it as part of the overall project, and not pass that particular part of the labor on! So, that is good news again! Makes two out of three, so you're a winner!....:thumbup: That's about it for now.... Don's baby really didn't want to go, it wanted to stay with me??... :jumper:... I've only ever had a few projects that I felt I would like to have when I was through with them! That is certainly one of them!..:)...til....lat'r...GT

Gerry, I've been going over your barrel threads and noting any interesting ideas. :)

In a previous G.T. barrel thread, Ron Wood posted -

I have that article/magazine, if there is any interest, I will post a PDF of it. I may have posted it before, but I saved it here somewhere... :rolleyes:

Now a barrel with a picatinny rail so it looks more tactical ;)

Gerben,

Is there a way not to thank you for your post. :rolleyes:

Rich,
do post the info and pictures of your sights.
I may be up to taking on the rear sight modification project, if
GT is too busy!:thumbup:

Not my sights...Skelton had a friend at MMC modify one of theirs...

I'll post it separately...

Progress!
 

Hi to all, especially Ed! Well, just as I thought, a little time in the "receiver torture rack" :eek: and we are now "straight arrow!" ....:thumbup: another receiver brought back to life for another go around... Anyway, I NOW have three to range test tomorrow... and although I'm a little concerned about excessive barrel mass on the 6" version, I think all should go as planned... hopefully..... we'll know tomorrow or Tuesday at the latest... :thumbup:.. I mean, bees don't know they're not supposed to be able to fly, right?.... Best to all, til....lat'r....GT...:thumbup:

excellent I like throwing 'lead' downrange like this :thumbup:

So I doubt that it'll intimidate me in holding it as I'm a two fisted shooter :rockon:

I suspect GT meant its effect on operation of the mechanism.

GT,
before you disperse your barrels, how about weighing them.
I'll weigh the baby and post when it gets here - starting a new thread.

Either with or without the receiver is ok, I can subtract an average receiver weight to get to bbl weight.

I've been weighing .30 barrels of different lengths and profiles related to the carbine project, will post the info in a "barrel weight" thread.

Weight of the recoiling mass has a direct impact on function of the luger, "velly interesting" sorting through what works and what does not.

sure, of course (not that I was thinking that :rolleyes:)

:p

not that its here or there, but it is interesting how heavy some aluminum magazine bottoms are, compared to other magazines. I wished I had weighed the assorted mags I've had over the years.

Don, could I suggest that you post a couple of threads??? The buildup of your 'baby' Luger, and the construction of your 'long barrel'/carbine Luger???

I like to read detailed descriptions of how and why others put together their creations. Why they chose to do something one way instead of another; what they think is more aesthetically pleasing; the mistakes they make. (There is only one way to learn; by making mistakes).

Ithacaartist has posted his rendition of tapering a Luger barrel. I found that interesting and even tried his method; it worked out quite well, surprisingly. (Well, surprising to me!) :p

I wish more of the members of this forum would post pics and explanations of what they've accomplished. :thumbup:

GTS/T Range test!
 

Well, just got back for the range where I tested qty. 2 of the new GTS/T-6 & qty. 1 of the GTS/T-4 versions... They all worked flawlessly on my byf test frame!!!! :thumbup:... Yeah Team!!... Now, I did have an owners frame for one of the 6 inch versions, and, with that frame, it wouldn't always close?... So, I swapped out the mainspring, original DWM, with the longer, and seemingly stronger Mauser spring out of my test byf, and problem solved.... All good!
Ed! Yours worked 100% thru 3 full mags of WW white box... :thumbup:... shot to point of aim as well... we should be good as gold if you have a decent frame for it... with the added mass, the receiver to frame has to be slick, any drag is a function trap! :eek:... Dons report should be forthcoming, but in shooting these two, my preference is the 4" as it just balances perfectly in my hands... More reports when the owners get there respective units to try / test?... But, I'm pretty happy... for now... best to all, til....lat'r.....GT....:jumper::jumper:

This is great news. I am looking forward to getting both my hands on my new toy. Thank you for working the bugs out of it.

Gts/t-6
 

Hi Dick, yes! It really ran nice! It will still need some trigger tuning... as all Lugers for target probably do.. but it shoots as good as I can shoot! And i'm pretty sure, actually, a whole lot better than I can shoot! ....:jumper:.... I just put my GT stamp on the barrel! The powers above must not like me doing that because I whack the hell out of it, and my stamp is barely visible? One shot only! The barrel steel is pretty hard? Or, my stamp has too much surface area... Either way, it's on them, ....:eek:....a little off center, but straight and square.... :).... When I get these sent, I will get back to the drum revisions... and all my efforts will be in that direction for a week or so... then a few more loose end projects... and then, sigh, more drums.... :jumper::jumper::jumper: Til....lat'r.....GT...:cheers:

drums!!
 

Hi Rich! I get it! ...:)... It's definitely drums along something!!! ... I have 50 of them tore apart right now...:eek:.... I dream about drums... I look at a tuna can and see a drum mag!... Must be my fate... Oh well, polish is the key... best to all, til...lat'r....GT...:thumbup:

Ed's GTS/T-6
 

Hi Ed, It's in the mail!!!! Christmas is coming! In June?.... :eek:... and from Arizona?... yup! I know it's a stretch.... But, those who know me well, know it's possible...:thumbup:... Thanks to ALL my customers! Best to all, til...lat'r...GT

very cool my friend!

I have a number of frames that I can swap around, somehow ended up with more than one shooter :rockon:

But can you play the drums? :evilgrin:

drums....
 

Nope! even the triangle was a challenge? ....:eek:... music abruptly ended about second grade.... :jumper:.... best to all, til...lat'r...GT

Short bull barrel arrives early!
 

Received my 2 3/4" bull slab side 9 mm barrel from GT today! Didn't expect it till Wednesday, so a great surprise. So I spent the pm assembling and slicking up the frame to receiver fit and filing the front sight blade install it.

This is for my "baby" luger project along with a 7,65 mm "normal" profile 2 3/4" bbl.

Got the 7,65 working a couple weeks back, so it will be to the range with the 9 mm installed tomorrow.

Pictures of the barrel and the baby in process are below. I wish now I had started with a prettier frame and commercial upper.
A slick back frame would be my choice now; but at the time I thought it might be a "wasted" frame, maybe next time.;)

GT and Ollie did work on the barrel, Jim Solomon built the grips,
a master welder did the 1/2" shortening on the frame, Sheepherder did the scallop on the toggle, and I was the co-ordinator and hand fitter of small parts and chief design engineer.:p

I'll report on the shooting soon in a new thread.

After function is assured, the next stop will be to have the piece rust blued.

I'm fighting the urge to buy the 4" upper that no one has claimed!:evilgrin:

Looks really cool!!! :thumbup:

Is that a Brownell's K98 Mauser front sight blade???

Gerry & Olle will need to design & offer a 'front sight blade pusher' next! :p

That's the oversized K98 blade, yes. It's supposed to be trimmed to fit, so it looks huge on that short barrel. :eek:

There's really no need for a sight pusher IMO. I'd just put it in a vice and tap the sight, the slab sides and a couple of wood blocks would hold it firmly without damaging the barrel.

I use a hammer & brass/copper bolt to push/install mine, but there's no vise at my range. I have a couple front sight spanners for my screw-on front sight bases and was thinking of tapping them for an adjustment screw...But they're aluminum and might strip easily...My blade dovetails are pretty tight... :(

Ah yes, I forgot about the poor bastards who can't shoot their guns in their back yard.... :p

I have never really seen a sight pusher that works, and I have tried in vain to come up one that does. Even with a bearing ball between the tip and the screw, it would spin and mar the sight when I had to crank hard on it. If I try again, it will probably be a clamp with a drilled hole where you can insert a brass punch. Really, a set screw would be ideal, but it would take a very tiny screw and it would probably strip easily, regardless of material.

Now when I think of it, it would be a worthwhile project to come up with a simple and fool proof substitute for those pesky dovetails. I think I'll do that, sell the design to a large gun manufacturer and get stinkin' rich.

front sight.....
 

Hi to all, Actually Olle, that is a standard Mauser K98 blade! Don, does have the custom front sight blade to profile and install, it used the one shown only because I was pestering him to get pictures up!.....:eek:.... But, I mailed Ed's out yesterday, and he has a profiled Mauser custom front, profiled and installed, and it is shaped similar to a shark dorsal fin?.... Only lower, looks neat to me?... I was really happy the 6" version worked with the standard Mauser spring! If I make another run of these, (maybe early next year!) probably about a dozen per year! They will all be 4" as I will get back to the philosophy of a standard Luger replacement barrel, but I will still offer a front sight option, as the Mauser blade give you the ability to cut the rear sight "V" into a square for a more modern sight picture, or use a standard "inverted V" as original.... I can't wait for the shooting results, I'm just not the guy for targets... I just like to hear the gun go off?... :jumper:... best to all, til...lat'r....GT

BTW, the machine marks come away with a small 220 W/D block sanding... Don is probably better than I in that department... but i'll bet it cleans up pretty! Til....lat'r.....GT......:thumbup:

BTW, Olle can cut the sight dovetail with amazing accuracy... right now, you have to take apporx. .005 out of one of the ends for a custom tight fit.... We planned it that way... the dovetail fit for the original Luger FS blade is perfect! And actually, my preference..... Again, Good Job Olle!!!!!!!!

In theory, I can...The first hole of Oak Run Golf Club is 363 feet in back of me, the bullet would likely plow into the ground before that...Or hit a tree...My neighbors would likely complain. But several years back, I was at a car dealership and I was standing close to a Cadillac...After about 10 minutes of my standing there, it drove off...I had no idea it was running... :eek:

I don't know what year it was, but I never heard it. If I can find a muffler for that car, I'll make up a test bench in my tool shed to shoot through it... :thumbup:

(BTW, there was a large deer standing at the back door of that shed yesterday...Dog was out pooping, never noticed it...)

My bad, I just looked at the way it sticks out on the sides! Really, all these barrels need to be sighted in after installation, so it's better to use a sight that's too large rather than too small.

Another thing worth mentioning is that I milled the sight ramps to standard Luger height on all these barrels (IIRC 10mm off the centerline of the bore), so this should hopefully be a good reference if you have to trim the height.

Most OEM mufflers are "turbo" style, but I'd say that a 2 1/2"-3" straight through race muffler would work. I think you said that you used Borlas on your Vette, so maybe you have one or two laying around?

Rich,
what an elegant idea, I've been thinking about a test fire tube for the shop.
A straight through muffler set up and pointed into the drainage ditch would be perfect!

Just a huge silencer.

Rich,
I'll do that. I've been waiting till I had the entire story ready!

Meanwhile how about a link to the "tapering" thread, I missed it!:eek:

Short bull barrel firing report!
 

Yes, it was a "new" k98 blade, the closest thing I had to fit.
As it was, I had to raise the base of the blade about 0.010" to clear the dovetail; I didn't want to change the bbl cut itself, as I may decide on a different sight.

Even with that one, I squared up the rear notch and widened it a bit to get a clear view.

I fired it today, worked fine with the same spring I was using for the 2.75" .30 bbl. Did not shoot at a target, just for function.

Ollie,
very nice cut for the extractor, looks just like the original! Good work. Do you use a shaped cutter or shaped grinding wheel ?
