Have You Seen My Tool #24 - Tapping Arm

[@peeposadboy]

Thought homie was having a stroke whenever he’d hit one of those long uhh’s. 😂😂😂

Went you your channel to get some pointers on how to make a better video and saw 3 vids and 9 subs. Are you really someone who should be criticizing?

Love the metal machining vids! Great refresher

Thanks for the video. Can you adjust the balance on the arm to make it lighter or heavier?

[@goldenhazeduster]

Thanks for watching. I wasn't sure so I had to go look. It uses one of those gas charged cylinders like on the hatch of a car. One end is fastened at a slot in the mechanism so I would say that you could likely adjust the balance by locating that end at different points in the slot. Thanks again for watching.

sweet score on the tapping arm. I have looked at them in the past, I seem to get runs of jobs that need tapping, but dont do it on a regular basis that much. So you drilled those 3/8 holes, right? no way they were plasma cut ?

[@goldenhazeduster]

I do those lugs on a regular basis. I actually do a larger version as well. My PM85 will not pierce 1" plate so I only edge start and cut the outside. I use my scribe on the CNC plasma to mark the location of the holes. I do the big hole with an annular cutter. The tapped holes are drilled 5/16" and chamfered both sides before tapping. Seems like a lot of work but the setup takes longer than the work usually. Some people advocate drilling a starter hole to do the inside features but the 2-1/8" hole only takes 2.5 minutes each on the Bridgeport. Cannot be much quicker to drag the mag drill around for a starter hole? Thanks for watching.
