G.T.S/T barrels report...

Looks really cool!!!

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

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

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

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....

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.

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...

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...

(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?

I have one that does work. But it's P.08 dedicated. Meaning, it doesn't work on anything else but a P.08 (tricky fellers them Germans ).

Attachment 59634

I tried to make one similar to that, but after measuring several barrels I realized that the band diameters can be very different (especially if you include the P1). However, yours looks simple enough, and if it does work I might give it another try.

Work it does. But as it fits the P.08 barrel band like a glove, It won't fit a P38, or even other Lugers other than the standard P.08, such as LP.08; 1904 Navy; or any .30 caliber.

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!......... 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?... ... 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......

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!!!!!!!!

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 ?

Don,

I happened to have a "divine moment" and realized that a corner rounding end mill would do the job, and after spending half a day on searching different web sites I found one the closely resembles the original cut. It's a bit narrower than the slot, but this works perfectly as it allows me to widen the cut for chip clearance as I go.
