Re: Questions about drilling titanium and SS

Let the bit cool between parts. Not that this is bad advice, it isn't conducive to proper machining. Your chips should be taking away the vast majority of heat. So much so that your tool bits shouldn't be getting "hot". You should be able to touch a drill/tool bit, immediately after the cut. If you...

Re: Questions about drilling titanium and SS

Let's assume you're drilling properly. Starting w/ a center drill, the hole should already be broken thru, on a thin part. Following with the final drill size shouldn't take too much effort. Pecking is a good practice. Let the metal, the machine, and the cutting bit tell you what should be done. Thi...

I doubt you'll find exactly what you're looking for. However, if you spend a little time researching, there's an entire thread for completed builds, many of which have plans in them.

Re: Questions about drilling titanium and SS

HSS is absolutely fine, for both SS and Ti, @ 220rpm. You don't need "tons" of cutting fluid. HSS can cut both materials dry and you're not going to make a ton of heat as the front of those cups aren't thick. A singl drop of oil, just to get started, is all that's needed. What do you mean "1/16 per ...

I am missing your point. Help me understand. Not that the OP's question has already been answered (correctly), several times, but you simply advise him to use an adapter an in no way advise how to do this (as the other replies have). As I said, "The SR22 has external threads... The OP doesn't". Yes...

Re: Recommended thickness for tube and baffles

1/32 is a bit fine, especially for threads used on parts meant to be threaded and unthreaded, regularly. Personally, I try not to go below 1/28. A properly made 22lr/rimfire suppressor need not have an OD >1". A wall thk of .049 should do it, but I'd go .058. I very much do not like the look of a si...

Re: Not enough barrel!!!!

Look at the design of the Ruger SR22 threaded barrel. There is no barrel protrusion. There is an adapter that replaces the thread protector and extends the barrel profile about 1/2" while also increasing the threaded diameter. You are likely to be better off with an adapter than with some other sch...

Re: How did I do? (baffle design)

I'd love to know more about your metering equipment. 116dB, on a 10" barrel, using HV ammo, from a 9mm design? I'm guessing your equipment doesn't meet Mil Std. There's no way HV ammo, coming out a barrel that long, and from a 9mm suppressor, will, not only remain subsonic, but yield metered results...

Your spindle mounted cat's head looks extremely useful. How do you center the stock and indicate using the four screws closest to the spindle? You can do it a couple diff ways: 1. The ability to insert a dead center, into the spindle, is still present. 2. If you just use the screws, you'll move the...

Re: Help threading barrel

That will work, but an outboard spider is not absolutely necessary. A lot depends on your equipment and what you're threading. Also, you should be able to indicate the chamber ID and not have to make a breech plug. The chamber was most likely cut w/ a piloted reamer and kept on the bore centerline. ...

Re: Practice material

get drops of 17-4. It's hardly expensive and usually cheaper than the typical materials recommended for learning (12L14).

Practice sharpening HSS tool bits. Good, sharp, HSS bits will cut just about any material you're going to turn, on your hobby lathe.

Make a male to male adapter, that threads into barrel and supplies threads for silencer.

Re: Stainless steel

I had to look the X15 up, but unless you can guarantee a full heat treat (quite extensive cycle for this metal), 17-4 will be stronger. Also, from what I read, 17-4 looks to be easier to machine, if that's a prerequisite. Are you getting the X15 for free? If not, I can almost guarantee that 17-4 wil...

Re: Which cones for 45 subsonic?

Yeah, I'd stick w/ the 60deg cones. You'll be hard pressed to mess up a build w/ them.
K's work, too, but can be finicky in their design and execution.
The Omega baffles, pictured above, take a bit of tuning as well. Not something for the novice, IMHO.
