Re: Golf ball dimpling/fluting with drill press?
It sounds like a job for a CNC mill with 4th axis, not a manual drill press if you want to keep what's left of your sanity. A $500 Harbor Freight mini mill (Seig X2, HF #44991) is a big step up from a drill press and will give you the side load capability for fluting when used with proper R8 collets...

Re: Coolant system for hobby lathe
The green stuff is mostly intended as a mist coolant sprayed with air, but it does say it can also be used as a flood coolant. They also list some synthetic flood type coolant on the LMS site as well. You can also find many options on the Enco site. If you at some point want to upgrade to pressure c...

Re: Anodizing at home?
Type II and type III anodize are equally hard as both build an aluminum oxide layer. Type III has a smaller pore size and is thus denser, but not harder, and it is also a thinker layer.

Re: Lathe/Mill Talk
The main thing I would change is shop space as my shop is seriously overcrowded. I am working towards that goal though and hope to move to a new location with a new 3,750sf shop building in the next year or so (current shop ~1,250sf). I have two manual Bridgeport mills (older and newer), two manual ...

Re: Lathe tooling? HSS, Inserts and brazed carbide?
Once you get some holders and start using "real" insert tooling you'll tend to not use the brazed carbide tooling much, perhaps just for custom ground form tools. The inserts perform a lot better, particularly since most have chipbreaker profiles and they are supplied in a ready to run sta...

Re: bridgeport series 1 interact
That's going to be a pretty old control and pretty expensive to repair if/when it craps out. You can probably expect to run it for a while, but long term a conversion to something like LinuxCNC or Mach3 will be in order. Such a conversion will probably run around $250-750-ish depending on whether yo...

NFA Marking question
Related to an SBR in this case, but generally applicable to any NFA marking. Is it ok to split the name of a trust onto two lines in order to allow the use of larger text? I read the specs in the ATF NFA doc and don't find any prohibition on splitting the name. i.e. J. J. Jones N.F.A. Trust Chicago,...

Re: grade 5 drilling question
4. Coolant pressure-fed drill bits, specified to work with Ti by the manufacturer, work the best and eliminate the need to peck. The Guhrrng RT100 VA, available from MSC for under $100, looked good to me and I could probably rig a low pressure coolant feed to it but, without high pressure, I suspec...

Re: Bore for 308 muzzle brake/Compensator?
If the adjustable reamer you used had a little setscrew in the tip, it was not a type that is adjustable in the way you were thinking. That type is only adjustable in the sense that the screw lets you expand it a bit so that it can be reground to the original size. The blade type adjustable reamers ...

Re: Helicoil for mount threads?
I was going to suggest solid thread inserts rather than the heli-coil type, but a quick search on McMaster seems to indicate that none of them are available with 1/2-28 as the inside threads.

Re: 50 BMG form 1 finally arrived. Making progress.
There seems to be a lack of fusion in the welding. I'd setup so you have something to rest your hand comfortably on and go at it again, also with more filler. Build it up a bit and then turn it down in the lathe to give a nice clean radius. You can weld in short sections opposite each other and let ...

The biggest issue is the end mills I have at the moment. I only have HSS .1875" with more than .5" LOC, and the ones I have are more like .875" so not very rigid. They aren't performing well even at a measly .005" DOC per pass and .75 IPM. I will likely end up ordering up some ca...
