First attempt making a tactical bolt knob for my Remington 700

[Black Jack]

This was my first attempt at modifying my original bolt to make a tactical one. Main reason I wanted to try that was because my thumb doesn't fit between the scope and the bolt knob when it was fully open.

Two short clips showing the machining operation. I saw a few on youtube and they had the jig to do it on the lathe or using it on a mill. I thought of making a jig out of a block of aluminum I had in stock and try it on my mill.
If i wasn't removing too much material per pass I was pretty confident that it would work alright.

Second short clip is the finish cut. My last .010"

This picture to show how I threaded the new machined shaft

Now the start of machining the new bolt knob

Finished new bolt knob

Installed on the gun

It works better than the stock version


Tks for watching

I can appreciate some nice machining, looks really good!

 

[Duck_Hunter]

Great job!

 

[Black Jack]

Thank you guys. I just thought about something. If anybody would like to try it out. That project or another small project like that. I would be willing to "lend" you my machines and tools. I'm east of Ottawa but anybody close who would be interested can contact me.

Great job.

 

[Gunneegoogoo]

Looks nice.

I might be getting a lathe with a friend. Hope I can do things like that one day!!

Don't worry about that Gunnee, it's not rocket science. Actually pretty easy when you know the basics.

 

[Trinimon]

Dang fine job there!

 

[gstprecision]

Good Job, looks good.

 

[VanIsleCam]

Very cool OP.

 

[photog_shooter]

Awesome job! That looks great!

 

[shawn]

Looks great

Why better than what I would have crafted with my dremel and dewalt drill lol

Looks great mate, nice to see some good old manual machining.

 

[adamskryan]

Awesome, well done

 

[zuke]

Cleanly done with nice line's

 

[Suther]

That looks really good. How long did it take, and how much did the materials cost?

 

[tiriaq]

Material cost is negligible. I generally make replacement knobs out of scrap barrels. i.e. free.
I use a commercial jig to hold the bolt in the lathe, for machining off the knob, and threading the shank. Downside to this system is that the jig only works with backswept Remington 700 bolts. Using a mill to machine away the knob allows most any bolt to be altered.

 

[Black Jack]

Tks guys, appreciated. Like Tiriaq said the cost was nothing. I had a 1" aluminium shaft lying around. Same thing for the jig, had the block of aluminium from something else I worked on. I actually made two half but realized that only one would work fine if I removed only a little material per pass. It was rigid enough as I was removing 20 thousands per pass. I didn't want to buy a jig since it was only a 1 of. It maybe took 30 minutes to do the jig. Another 30 to make the job.

It's always fun to create your own thing, visualize what you want and design the tools to finish it.
That's the part of machining I like the best.
Nice work.
