Affordable diy solution for repairing wastegates on Ford 2.7l and 3.5l turbos.

The wastegate arm needs to be fill welded and reground. 2hr repair!

Cool!
Why with a mill bit though?
Cleaner more precise hole diameter?

Gotta be slower than utilizing a drill bit, no?!

Annular cutters remove less material than a drill bit to arrive at the same size hole. They will tolerate higher rpm too. With the back gears the press will drill a 1" hole without a pilot using a fluted bit.. It just ends up being slower.

The weld shop at work uses a Roto Broach cutter for putting holes in thick plates. Does a nice job.

Over 3 decades old Oerlikon Fincord, 3.2mm stick (core) at mere 105 Amps.
Melts so nicely but keeps drawing magic smoke out of my welder.
We'll see what happens when the magic runs out!

Started this afternoon on this. Weld shop put new mount pads on a rotator for a clam shell bucket. Have to mill flat & add 18 M24 X 3 holes. Tomorrow’s project.

Progress. Still learning how to run this machine. Couldn’t find a machine arbor that fit the tapping head. The guy who set the tooling up for the machine no longer works for the company. It’s a scavenger hunt finding tooling. Thread milling tomorrow.

I see You utilize collets to clamp Your tools.
What ER size are You using?
Will You use a one and done machine tap?

Using ER32. Used a thread mill to cut threads. Did not have anything to hold the big tap head we have. It has a 1.5 inch shank. We use it on a horizontal mill we have. Wasn’t bad after setting it up. Ran about 25 minutes for 9 holes.

Finished up this morning.
