Turning my TOZ into Super TOZ-78-01
Well I have been tunning on my TOZ or you could say personalizing it.
Was going to shorten the barrel down to 16.5-17" but I wanted to slug the bore first.
I had my machinist friend make me a simple bore guide out of aluminum and it turned out very good.
So on with the bore slugging & I found that there is a choke where they put on the front sight band...so I am not going to shorten the barrel...oh well.
My TOZ does indeed have a LH twist rifled barrel. (anybody have LH barrel twist wind charts)

But in this picture you can see the alum. bore guide with most of my cleaning supplies.

I have a .17 cal rod with a .22 cal. jag adapter in the bore in the picture.
Can use a .22 cal rod but must break the action down & remove the ejector plate.
The next thing I done was disassemble the complete receiver & bolt, cleaned & de-oiled everything.
Then got all my wet dry sand paper out & my Dremel with the rubber abrasive bit.
De-burred & knocked down any Sharp edges, then I sand papered all the metal to metal wear areas....like 320,400,600,1200 then down to 1500 grit paper for the final finish
After all that I put the action all together now its time for the JB bore paste...smered all over all the working bolt parts & inside of the receiver.

My bolt was just fine with the bolt lift up & down but just OK forewords & back so I did most of the work there....forwords & back 75-100 times.
Then its time take every thing apart & give all the parts a very good cleaning.
See all clean.

Everything is re-oiled & greased.....nice & slick now...:bthumb:
One more thing is I polished 1 of the sear levers to get rid of the grainy creep. She has a very nice trigger.

My extractor claws need a little tune up but I couldn't get the pins out...will work on that down the road.
Now I get a little carried away with my tune ups ....but is fun to do & very rewarding with the bolt cycling.
Ya never know when you get in a fire fight with some squirrels in the woods.
I did this exact thing to both of my 2 CZ's ....they needed it very bad & can cycle the bolts with two fingers now.
Also did some JB bore treatment to my CM-2's cocking cams.
I will work on the stock a bit later down the road...just going to take my time.
Ya know shoot a little then tune a little.

Looks nice. I will have to try your bolt trick on mine as my bolt is very stiff. Good writeup.

Charlotte 05-27-2010 10:10 PM

Nice work! I did the same thing with my CM-2 bolt but went from 600 to 2000 grit paper and then JB'd the dickens out of it. If feels and sounds glassy.

midwest swiss 05-27-2010 10:21 PM

What do ya think Charlotte....a person could skip the wet dry sand paper
and go wright for the JB bore paste ???
All this helps you to bond with your rifle too....LOL

Very nice. How'd it shoot before the tuning (I'm sure we'll hear about the after results soon).

I've been looking at a 78-04 for my son, they are very reasonably priced.

Nice work, makes me wanna try . . . :eek:

The TOZ -78-01 or any TOZ-78- series would make a very nice rifle for your son.
What I am going to do to my TOZ will not make it more accurate but will make it more fun to shoot. The rifle is very accurate so far...:t
I wouldn't have to do a thing to this rifle & would be a very nice hunting rifle now.
I am just fine tuning the rifle....:)


Charlotte 05-28-2010 08:49 AM

Swiss, I did only the JB on two of my CZ's and the improvement was slower to achieve and not quite as slick as using wet dry paper first. I guess your drift was to suggest that others might feel squeamish about removing too much metal from the bolt and that they could skip the paper. The idea is that polishing is what you are after. JB is pretty safe.
I have to agree with you on it being a bonding process with the rifle and making it feel distinctly yours.

midwest swiss 05-28-2010 09:15 AM

I guess it kind of depends how bad your rifles bolt or receiver is....too use sand paper 1st.
Here is a picture of one of my CZ's bolt part that was really bad & the wet dry sand paper was the only way to go.
Or send the rifle back to CZ.
Thats one of the reasons that Cooper & Anschutz rifles cost so much. (more quality control at the factory) & that cost $$$
JB is like 1200 grit & is lab-grade volcanic ash and is non-embedding....from what I have read.
If a person uses valve lapping compound you run the risk of embedding the compound into the steel of your bolt...not good.

Which exact papers are you using for this? Purely wet/dry paper, the black type?

Yes the water proof stuff (Black)
To sand flat objects its best to wrap it around something flat...small file, pop sickle stick ...ect.
Then when you sand inside of the receiver use something round...wood dowel, brass round stock, magic marker....ect.

Give it a shot...:D


NOOk22 06-03-2010 03:18 PM

I also have a little dremel 'polishing' kit with some red putty in it. I thought about using that on some of the felt and cloth wheels that came with it. Would anyone happen to know what 'grit' that putty would amount to? I have several old .22s whose actions feel like they are stone on stone.

Super TOZ-78-01 project continues, stock & receiver upgrade
This week I took the rear receiver hold down screw & the helo-coil style wood nut in the stock out.
What a joke of a system....;)
I re-tapped the rear hole on the receiver & used a #3 drill bit & taped it to 1/4-28 fine thread.
I think this will work....but only have two threads too work with....:eek: I will torque bolt to 18-24"lbs with my torque wrench.
If it don't work I will have to silver solder or epoxy a steel block to the reciever & re-drill & tap.
And am pillaring for the rear 1/4-28 bolt. I went to the hardware store looking for some pillar material
& came up with a air-hose adapter made out of brass.
I chucked the air-hose fitting in my drill press & took a file to it. (poor man's Lathe) :D

Am going to try and be care-full, I would like to keep the stock finish original. Well maybe a few coats of Tru-oil.
I will have to do allot of care-full hand filing to make the brass pillar sit flush.
If I flub-up she will get a camo-paint job.
This TOZ will get a glass bedding job down the road....its going to take some time.


midwest swiss 06-04-2010 01:10 AM

Few more pillar job pictures

Now just let the Brownell's Acraglas Gel set up for a few days.
Good stuff that.....Acraglass Gel I like to mix the Gel with there brown dye also.....:bthumb:


midwest swiss 06-05-2010 02:17 PM

The Super TOZ project continues.
Let me take a step back & this is what I did with vinyl electrical tape before anything got epoxied.
I wrapped the tape around my barrel & the rear pillar screw so everything would be centered for the epoxy.
One of the problems with the "Red Head" is when I relived the wood in the barrel channel to float it everything was fine.
But when I would take the action out & reinstall the barreled action it wouldn't be centered in the barrel chanell any more,
the barrel would be touching the wood again.....so that is what I am fixing along with the rear action pillar and new rear hold down screw.

Here is some of the Brownell's products that I use...and has worked very well for me for the last 4-5 years.

The modeling clay I got locally. I can't say enough good things about the spray on release aerosol....:t :t
The bottom of the pillar is done & turned out good. Just need to use some Tru-Oil finish on it.

She is sitting now in the glass bedding epoxy taking a nap.

The "Red head" is coming wright along.


midwest swiss 06-06-2010 05:01 PM

Well the TOZ had a good nap & I took the barreled action out the stock.
It looks kind of bad at this point.
The stock cleaned up very good with the help of a file, X-actco knife & even a
little Dremel action. I bedded about 1" of the barrel too, the green arrows mark
where the action will be locked into the stock when the receiver screws are
torqued down. This will make it so the receiver can't move forward or back, (that's my theory anyway)
since there is no recoil lug...its just a friction fit from the factory.

I did have a stroke of luck, I still have an old bottle of stain from my 1st stock refinishing kit from when I was a teenager from the 70's....:D
The old stain matches up, perfectly orange....I think the gun god's want me to keep this TOZ stock orange...;)
Here is how the rear receiver recoil tang epoxy lug turned out.

Not to bad...:t may touch it up a little more ???
Shortened a 1/4x28 bolt up & installed it last night....it took a few trial fits 3-4 times.
I even took the "Red Head" out to the range this morning & she shot very well.
Shot my 1st insect with the TOZ @ 50 yards with RWS Target Rifle.
