Re: How precise on length dimension stipulated on Form 1?

Measure twice, file once. :) That's fine if you know exactly what you want to do & how you're going to do it from the start. Before E-form when you had year long wait times, many people (me at least) got the forms in & had "plenty of time" to figure out what to do once the stamp came in the mail. I...

Re: Clipping cones / best form to clip them

Thanks for the pic, link & info. Some parts porn.... Titanium tube ready for ends. Steady rest marks not cleaned up yet but after welding. The bronze plug sticking in the end I turned to gauge the ID all the way through. The little stack of baffles are all grade 5 titanium with one stainless steel b...

Re: Clipping cones / best form to clip them

I will have to search for a good link or image of the "triple clipped" baffle. I have most of the hard stuff done thus far like all my baffles cut and mostly complete. I need to make my 5/8-24 threaded mounting end that will be TIG welded to the titanium tube and a threaded end for the tube exit. ht...

Clipping cones / best form to clip them

Working on my form 1 can / .308 with titanium tube, baffles , end caps , SS blast baffle , etc. I am using the classic 30 /60 degree cones and as I understand clipping them helps dwell ( slow down) the gas expansion and induces turbulence. Looking at various other designs what would be the best styl...

Re: Can Titanium Tube be joined to Stainless Endcaps without threading?

Cutting Ti with carbide tooling works well, using high speed steel cutting tools or band saw cutting it sucks rod. The heat likes to stay in the Ti, it's abrasive and generates heat. I am working on my form 1 can (. 308) and just about finished with the baffles in grade 5 Ti. My tube is grade 9 and ...

Re: Titanium tube question

Most common tube used is 3Al-2.5V (Grade 9) tubing.
Baffles made from 6AL-4V (grade 5) round bar are pretty tough.

Re: Brake VS Flash hider

A brake suppressor mount takes some of the wear & tear off the suppressor blast baffle. If you are running a short barrel ( under 16" ) I would use a brake / suppressor mount. 16" barrels and longer are not as punishing on the suppressor blast baffle as the short barrels. As to how effective brakes ...

Re: Threading help

If you try to cut threads in one pass you will not have any threads.... I like running slow rpm ( back gears) and light cuts / multiple passes. If you are using a carbide tool or insert be sure to stop your threading pass the same each pass. Nothing worse than letting the tool travel past your cut t...

Re: Titanium Wall Thickness at Threads?

You're right, the original question was regarding the machining not legalities of a part I don't yet own. That being said, I'm not actually sure if my question was answered. Bender said he'd suggest 24tpi but is he saying the 20tpi is unsafe or just not as good as 24tpi? The coarser pitch thread ha...

Re: Questions on heat treating

You can flame harden smaller parts fine with an oxygen / acetylene torch. Use a neutral flame to evenly heat the part then quench. You should know the hardening temp, quench, then you will anneal or normalize the part. The temp needed depends on your material (tool steel, alloy steel, etc.) and quen...
