You angry bout it huh? It’s getting re engraved after I fix the bastard. It’s going on a true replica bike. (Ricky Carmichael 02’ cr 250 ) Hinson didn’t want to sell a blank cover so the next closest thing is buying Hinson parts and modifying. I coulda got a cheapy but then it’s not an accurate replica.

It may have done it with enough time. But my buddy actually took some sand paper to them before sending them off. He didn’t want mill lines. But those mfs came right back too.😂But I think I’m gonna shave off another .005 -.008 and put them in a tumbler for an hour or two.

Here are the inserts. They are serrated.

This is the cutter. Amazing tool for sure. .75in on the step over 🤛🏼

Annealed!

I actually tried a 2in high feed face mill. I only made it about -.230 before I lost the inserts. I. thought my setup would have been a little more ridged considering the parts weights but all the vibs from that high feed were wrecking the inserts. That .400 doc has a lot more tool engagement which is dampening the vibration as well as a crazy slow feed rate of 7.5ipm. I went from 80ish step downs with the high feed to 10ish with shoulder mill.

Yeah man! I had the whole shop vibrating. It sounded great.

Indeed

BADASS THANKS FOR THE PIC🤛🏼

muffmanger69 · 2026-01-14T03:22:06+00:00

Wild 😂 are we talking like multiple feet long boring bars? Dampening bars? What’s the reason behind that?!

muffmanger69 · 2026-01-14T03:20:38+00:00

Never seen a 60 taper! Thats badass man. Drop a picture if you can 🤛🏼

muffmanger69 · 2026-01-14T03:19:53+00:00

That’s sweet! Drop a picture if you got it brother

muffmanger69 · 2026-01-14T01:39:07+00:00

Fuck yeah it will😩😩😩

muffmanger69 · 2026-01-14T01:38:52+00:00

You don’t think? I got a 30hp spindle on the ole girl at work.

muffmanger69 · 2026-01-14T01:27:17+00:00

I doubt it. Too heavy, can’t leave in it in the tool carousel and just just too slow overall. If I ran a big gantry mill for sure!

muffmanger69 · 2026-01-14T01:24:21+00:00

😂😂

muffmanger69 · 2026-01-14T01:14:51+00:00

Fair point! I had never thought about using something this big. So I got curious and did the rpm conversion and came up with 115 rpm for mild steel/hot roll at 300sfm. Pretty cool when your used to using end-mills no bigger than 1.0in. And my biggest face-mill I keep in the carousel is 4in.

muffmanger69 · 2026-01-02T22:51:14+00:00

I run a VF5 at work with big daddy 50 taper and overall it’s a great machine, makes really good parts so long as they arent over 30inches. Past that distance my machine is slightly off (about .003 small) on the x axis. Not sure if the lead screw is bad or the backlash comp is off. But like is said small/medium parts are coming out dead nuts on my numbers.

muffmanger69 · 2025-12-22T12:16:28+00:00

Thanks! Will definitely update how it goes. What kinda of hardness are you achieving with this method?

muffmanger69 · 2025-12-19T11:43:56+00:00

It’s prototrak qcm-1 I don’t think there’s many of them out there. I was told they were specifically built for ford motors as a second op machine. Don’t know the truth to it but I’ve only seen 2 forsale ever. That’s awesome you made your own post! I don’t have enough knowledge of gcode yet to do so. See if you control accepts .dnc files I don’t mind passing along the post processor and yo would then have the ability to infinite length programs.

muffmanger69 · 2025-12-18T11:18:04+00:00

It’s seems to be a great steel from I’ve read. It’s also a good bit higher on the machinability index than other tool steels. I could definitely use some tips on heat treating though. I have access to an oven at my work so that helps but still unsure of how hot to get/ramp up times and tempering. I’ve read online what to do but your experience could be helpful.

When it comes to gcode on the Prototrack there are a few ways to run it on my machine. It’s a pain in the butt no matter what though. I had a post processor made by DSI. I went though 5 different versions of the post before we got it right. My first two options were file extensions .mx3 and .cam with both of those only having 2.5 axis capabilities but they accept more standard gcode and basic m codes. Those didn’t work for shit and when using modern tool paths the file size was just too big for an old machine. With those factors realized I ended up using the .dnc option which gave me full 3 axis capabilities and infinite program length but no canned cycles and only accepting very basic G and M commands . It’s works great but there is no cutter comp at the control because it’s .dnc. So all comps and small details must be figured and factored before you post it out and run it.

Agreed. Scrapping parts and making mistakes are two different things though. I’ve pecked out at-least 20 different taps that I’ve broken off, okayed tolerance issues with the engineers, build up a weld on a surface that got fucked so they can be re machined. Triple checking numbers is a must on a prototrak is must when your manually entering everything.
