K-Baffles step-by-step

Yes, it can be legal to make a silencer. For everything Form-1, from silencer designs that are easily made, to filing forms with the BATF, to 3D modeling. Remember, you must have an approved BATF Form-1 to make a silencer. All NFA laws apply.

Very cool pics. I tried the countersink thing reciently for a buddies project and it diden't work to well with A-286 material , ended up using a carbide tool and the compound.

Thise look pretty sizable what are they going to be used form"

Thanks for the pics. Is the angled hole drilled at a 45?

Excellent write up. Is the countersink tool a standard counter sink or a special tool? To get a sense of scale for me what diameter is the stock you started with? Thanks again. akraven

The countersink is a single flute 60 degree 1.25" dia sink. The stock diameter is 1.5" 6061. The chuck is 6"

Nice work, are you planning on coating the baffles?

Very nice setup there. I use a Grizzly combo lathe/mill, no where near as nice. Through a little bit of experimentation I ended up making my K baffles nearly exactly the same as above. I posted a photo tutorial on my website, but since the site got so little traffic, and I never really received any input on making silencers, I took it down. This website is a much better source of info.

I am rarely able to make perfectly centered holes with a drill bit in a tail piece stock. I end up using a 1/8th tool bit to widen and center the hole.

The inside reamer works great until I get about an inch wide. I finish larger baffles on the inside with the tool post feed in at the appropriate angle.

I prefer using the compound and a boring tool myself.

Any advantage to that? Seems a 60 degree reamer or countersink would yield similar results with less effort.

I tried both and using the compound/boring bar was about 2x faster

The reamer makes quick smooth work with small baffles, but when boring larger holes it tends to bind and gall, especially aluminum. I found that using a tool bit fed in at the required angle is faster and less effort for baffles larger than one inch.

Excellent photos. I'll be sending in an F1 after my Wolverine is in my hands, so I can make a can for my .308.

Thanks for all the comments.

I like the countersink only because I find it slightly faster. Others may find a compound rest faster, but I think a sharp single flute countersink is pretty fast. A multi-fulte (especially a 6-flute) would be much slower.
