Latest Project: Toz 8- Single Shot Rifles; Thoughts and Impressions...

[MarkRohfrietsch]

It arrived Thursday, and after a quick clean and lube I headed for the range.

Lots of opportunity for tuning... I initially found the trigger to have a long, gritty take up. Target 1 was me struggling with the trigger; once I got the "two stage" thing figured out (too many good triggers on my CZs) it was shooting much better.

The gritty take up can be polished out, there is room to add an adjusting screw to reduce the long take up some, and also to reduce over-travel. The #### on close also took a bit of getting used to, as did the internal loading nest in the bottom of the receiver (which works very well).

The target was shot at 20 yards last night in our indoor range from sand-bags; targets were shot in the same order as the numbering; all were 10 shot groups except number 5 which was 15 shots.

I find that keeping the sights in focus with the target very difficult with my post cataract prescription glasses, but I think the addition of peep sights should fix some of these issues. A stock refinish should "pretty" it up a bit. For a rifle that landed on my doorstep for < $250.00, I am very happy.

Here are a couple photos...

#2 and #3 look pretty good. I don’t have much experience with Canadian 22s. I shot a while back a pump and lever action but it wasn’t very accurate or powerful for me. I know with the right ammo it changes everything. But still with average ammo I pumped all day without thrills and was not satisfied. You on the other hand have some sort of a different viewpoint than I and have a plan.

My friend has a TOZ 14 repeater but it was missing a sight. I traded my ring and post sight for a front globe sight. We mounted my sight on his rifle earlier today. I had to do a bunch of work with a pencil grinder and files to create a dovetail in the sight ramp for the globe sight; took less than 1 hour including removing the ramp, reworking it, and installing it and the sight.

That’s pretty clever use of tools. Don’t ask me how you did it with a pencil grinder. That for wood. I appreciate you telling us about it. What more tricks have you got to do on it. Toz-8? What’s next.

We use pneumatic pencil grinders at work for fitting inserts and components into molds and dies; we also use them for cutting vent channels in injection molding dies. I have both at home. Depending on the job we have carbide cutters, diamond burrs, stones etc. we can use.

Polishing and tuning the trigger while I hunt for a globe sight. and refinishing the stock would be the next two thiings on my list.

Polishing helped a bit, I was also able to do a bit of shimming underneath the trigger spring screw reducing the pull by (guessing)30%, Second stage is about 1.5 lb. now. I'm now cleaning up the stock a bit; I stripped the shellac finish with acetone and have tow coats of tong oil; I want one more. It cleaned up OK.

I don't like that it has two action screws; the one in the recoil lug is great but the one in the tang is a coarse wood screw about an inch long. I think I will drill and tap the wood for a steel thread insert and replace the flat head wood screw with a metric machine screw. (I have seen rifles where these have stripped out, and the common solution is to put in a longer wood screw. We can do better! LOL

You’re going to town bud. Good solution.

@MarkRohfrietsch when you said Pencil Grinder I pictured those foul-smelling decices we would use in school that if we were very lucky, were motorized, that sharpened our pencils while filling the classroom with the noxious aroma of wood shavings, chipped paint and enamel and pulverized graphite dust.

Our grandparents with their inkwells did not know how good they had it, nor our grandkids with their computers.

By the way why is it that so many of the best industrial tools are German, Swiss, Liechtensteinian, South Tirolian, Austrian, Belgian, Luxembourgish, Dutch or Scandinavian? I can’t think of an industry that does not rely on at least one company from that region for a critical part of its manufacturing from that region. For example, the latest semiconductors rely on Dutch extreme ultraviolet lithography machines from ASML using German optics from Carl Zeiss, which for a complete unit cost about $400 million and require a 747 to be shipped, and which were based on technology in development since the mid 1980s.

At any rate that sight looks splendid. I am blown away you were able to fabricate with such precision and elegance!

This was actually a bit of hack-job; when I start in to add some vents into a $400,000.00 mold with a hand held grinder, caution and a clinched sphincter punctuate the seriousness, and the high stakes. different ball game than a $200.00 rifle.
