    Hi Guys! 2007 4020 Ok, on-board program for rigid tapping exists. I purchased the fancy piece of all-thread... I have no idea the procedure. I have been using floating holders because my gain is off. There isn't a thing in my books on how to tune it. This would be a real help if I...

    Can you get a carbide drill through a broken easy-out?

    Broken stud removal is pretty common work here. And I am pretty good at it. I have yet to find one I could not beat. When possible, I weld-nut my way out. If things look reasonable, I may try the Snap-on style easy out where you drill through and drive the easy-out clean through, and...

    Best method of removing valve seats from Aluminum cylinder heads...

    Hi Guys; I recently started doing cylinder heads on my CNC... Due to the lack of anyone else in this town doing them. But getting those valve seats out is the worst of all. I hate machining them out as when they get to the give point, they can go all at once and run a thick section in...

    Plunge roughing.... do you use it?

    Hi guys, I have always avoided plunge roughing. It just seems a bit harsh... I always drill a pilot when I have to do it, but honestly, it is not my favorite way to clear a pocket. Am I thinking wrong that this is harder on the end mills, or do I just need to refine my plunge rates...

    Good training for fusion 360???

    Hi guys; A couple years back I spent an entire two weeks in the office trying to transition from Bobcad V 32 to Fusion 360. I streamed hours of video, had notes all over the desk... I like the software, but every video was in another version, and the software seemed to be a moving target...

    Cylinder Head Work Port and Polish

    Hi guys; I have been doing some cylinder heads, and there is call for porting and polishing. Well, that gets too far off track for me, unless I could come up with proven CAD models, I just don't have the time or inclination to start doing port designs and doing all the dyno work and tail...

    Machinist's tape

    Hi Guys. I just did a job cutting plate parts 1/8" thick. I started on MDF with carpet tape. As soon as the coolant hit, it let go. So, next adventure was Hippee tape on UHMB... Much more stable, but same problem when coolant hit it. It released. Is there a double stick that can...

    Is there such a thing as an undersize tap?

    Hi guys... I am wondering if there are undersize taps. Like a h-2 I want to tap a hole, and have to force a set screw in there. Can't use lock-tite as temperatures will soak at 400F + In Aluminum. 5/16 coarse. Maybe I should just take my roll tap and top it on the grinder for...

    Hot Rodding a TM-2

    Hi guys; I love my 2009 TM-2, but because of it's speed limitations I haven't really put it into production... Odd jobs and prototyping. Just too slow for production and fine finish work. I started digging. Here's the stuff I have done to make it go, and it's made such a difference that I...
