Who does Bolt Knobs for CZ's?!!!

[BenY 2013]

FINALLY got in touch with CZ and have to bolt knobs headed my way. Once I get them I am going to start testing and see how things go! I'll keep you guys updated in the progress.

To the guys who are wanting this done to their 452s, I'll have to have one of those bolts to modify the jig slightly. The 452 has an extra lug that is absent on the 455 bolt. But I still want to try and offer this for the 452(and most likely the 453 if the handles are similar) guys once everything gets going with the 455s.

Thank you brother for your efforts

Whoever you get to do the install it is well worth it. I just had a Savage knob I got from DIP installed on my 455 by a local smith and it feels great. That knob and the Manners stock feels just like my 700. BenY, you will be busy once you get rolling. Sorry I couldn't wait!

I would be happy to let you use my 452 bolt to help you set up, if needed.

I finished threading a couple today.

Made some scaled down knobs to compliment the small action. Left the handles factory blue and Cerakoted the knobs Graphite Black

Nice work, I really like the scaled down knobs.

 

[Kiba]

Nice.

While I don't own a 455 myself, a good friend has a 455PT... and if you start selling these let me know as I'll pick one up for him.

 

[gafferq2xl]

Great work EG. Wise choice going to scale. Looks MUCH better than with full sized knob.

 

[mscott]

Here's my latest one. I had a handle off the bolt, so made a piece that allowed me to bolt it into the Rem 700 style jig. This handle was sent with a PT&G knob to install, so the end is really small, which doesn't leave much room for a shoulder. To get the angle right I had to leave a little of the existing knob on the bottom, but can be smoothed out easily enough.

Anyone here want to do my 455 bolt handle? The stock one on my built 455 is kinda like having stock exhaust on a full build Harley.

 

[BenY 2013]

I'll finally be testing mine on Tuesday or Wednesday this week, I'll keep everyone updated!

Tag for the list

Ohhhh I'm sooooo in for my 452!!!!!

 

[BenY 2013]

Well got around to testing it today....

The jig is going to work fine I think, had no issues with it. But... my HSS cutter isn't going to touch that thing... It just won't eat into that metal for some reason. Slowed the rpm down and it took a VERY light amount of metal off but that cutter is toast.

So new game plan is to find a cutter with the exact same dimensions except either full carbide or a carbide toothed cutter. So if anyone knows where I could have a custom cutter made I'd really appreciate the info.

Really sorry guys. Made me sick when it happened... I'm still wanting to go through with this but obviously it's just going to take some time.

Yes, they are hard, but not impossible. Win mod 70 knobs seem to be even harder than the CZ's and every now and then you find a really hard Savage knob. Try carbide cutters. The only problem I ran into is the casting voids that are inside the material.

 

[gafferq2xl]

mscott, the PTG knob looks to be perfect in scale, angle and position. Truly fine work.

It looks even better on the rifle!

 

[BenY 2013]

Got an update. A very good machinist friend of mine found a carbide cutter that should work and a couple of those tools are on their way. If that does't work then I talked with my machining teacher and he gave me another good suggestion. So it's going to get done one way or another. I apologize it is taking so long. It really is sickening to me that it did not work the 1st time...

Don't beat yourself up over something your still learning about bud. I for one appreciate your efforts, carry on.

I ordered one from the guy in Australia. Works slick. I have a CZ452, vortex 2.5-10 PST and I have no clearance issues.

Here's my latest one. I had a handle off the bolt, so made a piece that allowed me to bolt it into the Rem 700 style jig. This handle was sent with a PT&G knob to install, so the end is really small, which doesn't leave much room for a shoulder. To get the angle right I had to leave a little of the existing knob on the bottom, but can be smoothed out easily enough.

The problem with leaving a shoulder is that the knob is not concentric with the handle stem. When you you machine the tenon it will be concentric with the handle if it was dialed in to it but the shoulder will be left eccentric. With this situation the only way to get the tenon and shoulder running concentric with the handle is that you will have to add metal, no two ways around it.

Here is my handle I did today. Everything is running true with one another and IMHO will look the cleanest but there is significantly more work involved.

If you are after getting a shoulder concentric with the tenon then you will need to dial the handle in by the knob and not the stem of the handle. That will throw the angle off and the knob will be going a different direction than the lines of the handle. I hope that makes sense.

The other way is to do what I have done previously and not leave a shoulder and just have the knob bottom out on the threaded stud. Here are examples of each, both are machined concentric to the factory handle.

 

[Slug-O]

Great work. Can't wait to send you my bolt...

 

[BenY 2013]

I think the way I am going to be doing them on the mill I should be able to get the handle flush with the knob. May take a bit of filing afterwards but I think as long as I am dial in with the knob well it should be very concentric to the knob. Only reason my last one wasn't is because my jig broke down in the middle of machining..

Still waiting on tooling...

[yoteman]

Ben glad to see you hanging in there.
keep at it an dont let it kick your a$$
you got to much into now.
i`am sure the new tool will help, but just maybe try an grind the knob down a little 1st

 

[BenY 2013]

Appreciate the kind words! Unfortunately I did grind off part of the knob before I did it this last time still ate the HSS like it was nothing. These new carbide tipped cutters should help! Patiently(oh what ever) awaiting them....

Ben

 

[cannoncrossfire]

I did 9 CZ452 handles on the weekend... C'mon Beny! I used a 40 grit linishing belt, ground the shit out of them (wore gloves and glasses so I could really flog it), threw them in a bucket of water when they got to hot and moved onto the next handle... Now i'm filling in the cavities with Silver solder so that I can machine them to a 6mm shaft, and put an M6 thread on them, blast, cerakote, assemble with knob.

i hear ya!!! keep us updated

 

[ltfirehunter]

So is anyone doing these for these yet for others, or are still just talking about it?

 

[xtrema44]

I have a 452 that I am planning on building.. I would love one.. Is anyone wanting to do one or has one please let me know.. I am willing to even send them mine to use..

All you guys doing them they look great!!!!!

 

[BenY 2013]

Planning on trying to do another one some time this week. Picked up another 455 action this evening. I thinking APA type bolt knob, AICS chassis system, Anschutz barrel machined to fit. Should be fun! Anyhow the bolt handle should be ready sometime soon! I'll be sure to post pics of the work!

very nice work!!!

Now you're cookin' with gas!

NICE!

 

[Slug-O]

Thats mad skills!!! Great job!!!

 

[el gordo2]

Here are a few I did yesterday. One is a 453 while the other 2 are 455's.

 

[Slug-O]

What's the difference between 452/452/455 bolt handles? They all look the same in the photos but there has to be something???

 

[BenY 2013]

I appreciate the comments guys, the handle should mate up a little prettier in the picture, this one isn't all the way torqued down yet. Thank you guys who encouraged me to keep working at it! I believe it is going to pay off! More to come!

The 452 (and I believe the 453) have and extra lug on the bolt that is absent on the 455. Should be some pictures of the bolt here: CZ 452 American vs. CZ 455 American

[Slug-O]

Ahhhh thanks for the link... Great info there...

 

[richardj]

The matching 455 and 452 handles above are mine (I'm guessing) completed by Charlie.

Received today and I'm very pleased with them. the machining and finish is very good (as expected) and most importantly (to me) the scale of the knob is perfect for a rimfire rifle.. (poor photos below).. On my 452..




455 build is underway..

[LongArm]

very nice

 

[BenY 2013]

Here's one that I am almost done with and thought I'd share, line up much nicer that the one before!

what material is the knob made out of Ben?
