You are not making enough videos but you are making videos with amazing amounts of information and detail. Always a pleasure to spend an hour watching them. Thank you , once again.

Thanks a lot for this video, I enjoy watching the way you attack certain machining problems a lot. Always something to learn. I am definetly guitly of infeeding from the outside with superabrasive wheels, I have to do a fair bit of reshaping on my wheels to keep them sharp-edged. Should definetly keep your pointer on that topic in mind.

Tool & die guy who works with Viscount 44 a lot. The stuff is available in generic form under drill rod manufacturers by different names, I think we get Precision Marshall Firechrome 44. From what I've been told, actual Viscount 44 is not being made now under original name anymore, but the basic formulation is available under different names for drill rod at least. A. Finkle FX T2 & T3 triple vacuum melt steel is great too- but much harder. Always wanted to make my own insert boring bar- so many are indeed poorly made. Your 0.005" pocket screw offset is what I've been told exactly by a custom small insert tool manufacturer near me who specializes in HSS insert tooling- most people don't know that detail. Guys- if you want to make one of these- he got every minute detail on it. I definitely learned a couple tricks. Would love to see a dedicated vid on the D bit geometry and radial relief grinding. Awesome work Robin, you make quarantine livable

Yay! A Robrenz video! It's a real treat to learn from a pro, he always points out details that I would have missed at first glance. Quick, somebody call Stefan!

There aren't many guys who I would sit through watching an hour and a quarter video with. You're the best.

Great video Robin! If I can be so bold and make one suggestion. If you mill the bottom of the pocket just slightly larger to leave a small vertical wall that goes about 1/4 to 1/3 the way up your side angle. That would give you a corner relief sort of like your top relief below the cutting edge. This would make it so you don't have to chamfer the bottom corner off those small inserts. Yet still leaves plenty of bearing area for the insert. Thanks again for taking the time making the video.

@ROBRENZ

Thanks Peter, I do that on larger insert pockets. I intentionally did not do that on these because the wall on the cutting side is already extremely thin and they have a tendency to just fold over and rip back destroying the pocket integrity. So I wanted all the meat I could get on these. ATB, Robin

Awesome channel, I have alot to catch up on.

As a Utility man (universal shop work and industrial repair) i enjoyed watching your video. Thx for taking the time to make it. You are a Master. Thank you.

If only I had a shop teacher 40ish years ago like yourself when I began my machinist career. I had to break alot of tools, and an occasional g-code crash 😩, to learn one fifth the information you pass along in these video. I sincerely appreciate your efforts making these videos and you sharing your expertise and experience.

Excellent work, I especially appreciate how you explain your workflow in designing the part. I also like your explanation of steps and the reasoning behind it. I learn a ton of little things most people would skip over.

You certainly set the bar high for everyone else. Nicely done and really enjoyable to watch.

One thing I have learned over the years is to take the time to consider all of the ways to do a machining operation before making a decision on which to use. My son and I used to make a game of how many ways we could do something before actually doing it. This goes right along with your advise to always consider future steps before rushing in to get the present step done. Both of this can result in some real revelations on how best to proceed. Thank you again for the great video as I know how much extra time it takes to video it.

I'm not a machinist but I worked in a shop that had several machine shops for both die and tool making. Love watching the journey you take when making things. You explain and show the how and why very well.

Way beyond my skill level, but fascinating to watch. I always really enjoy your content. Thank you.

That is some very clever modeling. Like a lot of old machinists, I never got any Solidworks training in design. Moving from manual machining to CAD / CAM / CNC was a big move for me. Of course most of us had some exposure to programmable DROs and conversational programming like Prototrak and Dynapath, but making stuff work in Solidworks was a steep hill to climb. It’s frustrating when you know what you need to do and you can’t figure out how to make Solidworks do it. At least I have my Machinery Handbook to fall back on. Learning how to use that was probably as hard as Solidworks if I’m being honest. But I was younger then and my eyes were better.

Unbelievable creativity & skill! You are an inspiration. Thank you! Please continue the cause for the army of people like me who gain giant steps with each video.

Always learn from you. This is better than classroom time. Enjoyed every minute of this.

Wow! this man is the Da Vinci of the 21st century's machine world

Thank you Robin for taking the time to share the knowledge. Always love seeing your thought process, almost more than the tips & tricks during machining. Take care, & ill be right here when the vid comes.

Thank you Rob - beautiful work, wonderful attention to detail. I certainly learned a couple of things.

As a hobby machinist I am blown away by your videos, and that is to be expected. You are of course on another level. However, there is so many things to learn from these videos, so if I can pick up only one or two things from each viewing I can greatly improve my skills video by video.

Great content, thx for sharing. A few years back I also made a tool holder for DCMT and VCMT carbide inserts and used my D-bit grinder so that I could mill out the 7° relief angle. A good CAD/CAM package and CNC mill ease the process of milling out required contours. This approach opens up further possibilities to fulfill those kind of special jobs :)
