So it looks like I have 7 or 8 guns I need to put over sized bolt knobs on to handels
what,s the skinny of doing this kind of work
the guns I need to do it on are savage/ stevens and some rem 700
I may as well make my own knobs but who here has done this before.
these are my questions so far
1 what size to cut the factory handle and knob down to?
2 that thread for the shaft and to tap the new knob.
3 how have you set up the bolt handle In the mill.
4 do your remove the bolt handle from the bolt body or just leave it attached when jigging it in the mill

Im sure between the 3 of us we could work it out but any advice and or help would be good

5/16 x 24 is the common thread...

The vast majority of home made ones are way too huge and ugly...

Defensive Edge and Badger make nice ones...
 
1) the correct OD for 5/16 x 24 thread OD of .3114-.3042

2) 5/16-24

3) depends on what im doing, 700s, im to lazy to make a jig, so i use a mill vice and thick rubber pads, no its not the best but im not a certified gun smith and i dnt want to invest in a jig.. savage- its less work to just buy a replacement handle thats already threaded, they can be had for less then $50 and come anodized, but the stock ones do have nice flat surfaces to clamp in the vice

4) 700s, the bold handle is soldered on so it stays, savage - undo that big hex- bolt on the back of the bolt body
 
thanks guys sounds like somthing we can do
GT yes some look like a stolen golf ball was thinking something more like this

I made up my own jig for the lathe. 5/16 x24 threads is what I use.
After that I make up my own knobs out of aluminum. I agree most are too big.

Here's one of many I've made. Most are smaller than that one.

Kudos on that jig Lejarretnoir. Your solution just emphasises how much machining is 95% is figuring out how to hold the stuff and 5% is the actual removal of the metal.

BBB, I'd take what Lejarretnoir did and maybe expand on that. Something that holds the round portion of the bolt with adjustable pads to align and steady the handle to center it. Perhaps even a way to alter the angle the round portion is held at. With a little head scratching to take his jig and make it a little more universal you'd have a rig that works on any bolt.
 
Length and girth are what you need.... (Stop laughing!)

There is not much of a point to a replacement handle if you do not add length to it to give more leverage and make it easier to grab the handle. I little extra girth helps, but don't go overboard.

0.7"-0.8" seems to be a pretty standard number for the thickness IIRC, and length varies from 1-2" depending on preference.

I ended up going with a badger ord. knob.
 
Anyone who can do the machining on the bolt can easily make a handle. Scraps of discarded rifle barrels work great. No harm in buying one, no need to, either.

maple_leaf_eh - your suggestion to make a universal jig is an excellent one. My PT&G only works on a M700 bolt. There are others.

One thing that I have done is to shift the axis of the knob slightly forward of the axis of the shank. This gives a bit more clearance between the larger knob and the knuckle.
 
Im more of a dedicated tool kinda guy, I may just buy the rig rather then make it, just need to find on for the savage.
longer a bigger is the plan that the teardrop shape seems to be what im after.
just have to work out if ill do it in Alum 4140 or TI
Guess depends how much I want to spend

PT&G knobs are $6.50 these days. I have no interest making one for that.
I bought an angled knob fixture from PT&G and it doesn't work as nice as the one I made for myself, but it does work well.
This one I did with my own jig.

I like the shoulder method.

if your happy your jig want to sell the other one?
 
Anyone who can do this want to make some extra money?
I have bolt handle, and knob, but there is not a chance in heck that I could even attempt to do it myself..
Happy to mail it, just shoot me a pm with a price :D
