Why do people feel the need to post stuff like this?If there is a reason it doesn't or wouldn't work for you, then feel free to post that.But stuff like this doesn't add to the discussion good or bad.Please refrain from posting useless comments in the future.

I don't think the statement is that bad. Certainly we are entitled to an opinion. The quality and level of work speak for themselves.

Given I can recognize the quality work, I took his post to mean that he really didn't care for the style. I think we have to focus on taking all the comments with a grain of salt. With it we have balance which is real life.

I don't know if he provided clarification at the time of the post or after.

Al,
What would you suggest to improve the gnurling?I left it not so sharp on purpose as I found the sharper it was,the harder it was on my hand.

If you don’t have one already, get yourself a scissor type knurling tool. Then watch your speed, low speed when knurling steel, remember, you are displacing metal not cutting it. Then pressure, steady pressure, with a generous amount of lubrication. Then a steady feed, to get a uniform pattern.
As far as the welding process, what are you using, stick, MIG? I suspect that you are using a stick machine, in that case, use a different type of electrode, if you are using a welding rod like 7018 for instance, you may be adding too much carbon to the joint, use a low carbon welding rod or a nickel steel rod.

Win/64 what do you care what I think? It's not like it's your gun is it?


But I'll explain.

First, the quality of the work is excellent, that's not my beef.
I do not care for the style and the huge knurling... that's all. To me the original, smooth bolt handle would be a lot better to cycle for rapid shooting.

No it is not my gun. I don't believe it's yours either. To "pipe" up and say it looks hideous is a stupid statement. Let's see some of your work :rolleyes:

I like it and think it will be very practical on a rifle used out of doors with gloves.
I don't have the tech to knurl something, but I am a welder. I would suggest of course using the most similar metals you can (which I'm sure you did) for the actual bolt handle, but what probably led to the very slight discolouration would simply be the actual welding process, heat affected zone, carbon precipitation, high alloy, low alloy, pick your poison. I would be tempted to try, and will this summer, welding with the GTAW process, 2% thoriated tip, ER70S filler, and 12psi Argon. Slow and low always makes for good delicate work. You could try Oxy/Fuel welding? same filler rod, just a torch instead of tig. I'm not a gunsmith by any means but there's my 2 bits, and if any of stuff I've tried looked that good I would open a shop.
 
BTW: I realize not everyone can be set up for it, but when welding bolt handles, TIG is really the ideal choice metallurgically... though just as good results can be had from ARC and MIG, though both of those methods generally require more work.

The single biggest factor is the jig you use coupled with sufficient heat-sink useage when welding.

Just my $.02 cents worth from an engineering standpoint. FWIW, I don't mean this as a comment in any way about Longshot's work - I have no idea what method he uses. It's just a general comment about welding on bolts.
 
I'm a newbie member here but I was wathching this forums for quite a while now.
My opinion in this matter would be that this a very good job from the manufacturing point of view.
I am not sure how practical it is, except for using it with gloves, as other members aleady have said.
I think that the fingers or the palm don't have to grip the ball, in fact quite the oposite.
Just my 2 cents.

Tig was used.I don't know.I find that the longer knob just makes for easier manipulation of the bolt.I'm not sure how it can't?

Some schools of thought prefer the smooth ball, and never really grip it, just let it roll in the hand as you pull up and back, then forward and down. You couldn't do that with the knurling, it would chew your hand/glove up. I prefer a smooth bolt myself, but also recognize excellent work when I see it, well done! (I thought you'd used tig....great system ain't it? you can weld almost anything and its clean and smooth). I'm thinking you must have knurled it before you welded it on, yes? Sigh, I miss my job with lots of free time and the run of a machine shop.........:(
 
Looking at the before and after pics, plus some of the comments. The old CZ bolt handle, while smooth, had a sharp edge on the tip of the handle where the recess is. So rapid bolt action would have still had a potentially fair amount of sharp edge interaction. I would have though that rounding that sharp edge would have been sufficient. All that aside, kudos to Longshot for making a bolt handle which makes his customer happy. That is the only person he needs to satisfy. Looks good IMHO, but I doubt I would every go to that extreme.
