new tactical knob for my LTR (pics)
- Thread starter yoyo
- Start date
I used hacksaw to saw off the sides of the old knob, then used bench grinder to get a cylindrical shape. Finished with a file and sand paper. Then threaded using a die. Just make sure that you don't remove too much material, don't let the bolt heat up and don't apply excessive amount of force in the bolt handle joint. The whole process only took me 2 hours so I can't justify the time and money to spend on a bolt jig.
Suchee:
I just used a die from canadiantire to make the thread. The whole set if I remember costs me 50$ and served me well. The sawing/grinding part is actually more challenging as you must make a near perfect cylinder of the right size by hand. If you are determined, I suggest you GO SLOW, and MEASURE OFTEN.
Here are some more pictures:
Protect the bolt from dust:
Saw off the bigger side of the old knob (less grinding):
Using bench grinder, file and sand paper to make the cylindrical shape of 5/16" diameter:
threading using a die, make sure that you support the bolt handle because threading involves quite a bit of force:
I can imagine.... I'm no metal worker, but SLOW is my forte! I have a new bench grinder and it needs a break in. I just want it somewhat ready, I use my guy way to much, plus with the BO instructions and your pics, he'll know how to recover my mess. He'll have a nice laugh at my attempt, but your pics are GOLD!
Thanks for the updated pics, really good for a hack like me

You could weaken the handle, or the handle could simply fall off. On 700s, they are brazed to the bolt body.
Machined the knob using 6061 aluminium:
threaded the bolt to 5/16"-24, same as badger one:
I just used enamel paint on the knob, result is pretty decent but I don't know about durability:
Few ####s:
What do you guys think?
Hay there YOYO, that look pretty cool, did you make that you self, I think I got the same lathe in my garage,
Here is what I got with my little time off at work, let me know what you think, Maybe I trade some of my goody with your!, let me know what you think!

Very cool brakes! I like the one on last picture the best. The finish on them looks great too. Is it parkerized?
The lathe that I used is the one from busybee, 10X18 if I remember right. The precision is great for a Chinese lathe, spindle run out is only about 0.0002". With a few projects like that the lathe comes for free
.
In fact I just posted my new muzzle brake that I made for my LTR. My design shows some similarities to your first muzzle brake from left. It's very simple and only requires a lathe. The efficiency is good for my .308 but I think it might do better if I could get a mill and make some slanted slots instead of straight holes.
I think I might be able to make some straight slots by drilling 2 off-center holes for each slot. If I have some time next week I'll see how it goes.

Thank, One of them is Parkerized, the other are bee blasted, it give rough finish.
I saw your muzzle break, it good to go, next week, I will have another different design, mines still pretty rough., all you need is a vertical drill, no need for a mill, I still waiting for my vertical mill, it will arrive next week or so, all you need is straight slots, because with slanted slots, it will produce quite a bit noise.
