Hi Quinn, Great show. I, and the robots, are putting your parts to use right now!

[jameslechner]

Very well presented. My favorite part? the metric 3" cube.

[kyfho]

3 years old and I've watched it again. Like most of Quinn's videos, there's always more to learn. Kind of a refresher, if you will.

Great job as always, Quinn.

So quick trick when doing the bolt circle! If instead of calculating the end angle, you just put in 0 and 360, you then just put 1 extra hole in and the machine does the rest! So in this case, you would have done start @ 0 degrees, End @ 360 degrees, 9 holes.

This is particularly useful when you don't have a 0 start angle. I've often (probably more than not surprisingly...) needed to have the first hole at either 45 or 90 degrees (aligned with the y axis), and find that doing the extra hole makes it just "start angle + 360" for the end angle.

Neatly done.
Shiny aluminum...oooh.
We have seen that cool deburring tool before, haven't we?
Thanks and Meow to Sprocket.

Ya know your sense of humor makes watching your videos a blast. If you press the button yo move the island, does it sound like the smoke monster?🤣🤣

[ducksauz]

Quinn, Thanks for another great video and thanks for showing off the bolt hole circle function on the DRO. I've been noticing that button and was terribly confused trying to figure out why your DRO would have a Kubernetes cluster. Now everything is clear. :-)

[routercnc]

Nice work - those DROs make hole pattern work so much easier ! For info those 'zero flute chamfering tools' are known as 'snail countersinks' (in the UK at least).

[emanekaf]

im about to buy my first mill, your videos have given me the confidence to go buy one and use one, i dont know anyone who machines so 100% of my knowledge comes from blondiehacks. thank you so much for the easy to understand videos, its really helped me so much, my life has direction again, wooohooo. i love learning!!!

[henrikskott]

I learned a useful trick from Stefan when using the bolt circle function: To avoid having to calculate the ending angle, put in N+1 holes, and you can always use 360 as the ending angle. The first and last (N+1:th) hole will be in the same position, and already done, but you save on brain cycles (subtraction is hard!) in the shop.

[TyrellKnifeworks]

Thanks Quinn! I have the same mill and have never used the bolt pattern so this was super useful!

[LordOfTamarac]

There has been an emphasis on your channel on beginner content, but I would love to see you flex on my complex projects. That being said the thoughtful and thorough commentary on every step of the process that you provide is invaluable! Love the videos!

[RonCovell]

Quinn - Thanks for another great video. I absolutely LOVE your description of the boring head! That was what got me hooked on your channel initially.

[StyxHackshop]

Thanks Quinn. Good to see some more techniques! The video angle that captures you working the mill controls too, is really valuable. Thank you!

[DavidLindes]

23:44 - thank you for eschewing corporate sponsors!!! And I received my patron stickers, so thank you for those, as well. Yay. :)

[OtisMamed]

Man, the timeliness of this... wanting to create some decorative holes on an aluminum wheel... AND... how the heck do you fit those darned long reamers when you don't have.... OH! That's how! Now I just need to figure out what my leftover angle is... heh.... (Beginner Hobby Machinist... same mill as you!) Thanks Quinn! (So, more DRO tutorials would be great!)

[TandaMadison]

buckle up we're going metric... this is 76.2 which is 3 inches. The reality for those of us who buy any kind of metal stock in the USA. Great work! love those sneaky little internal deburring tools.

[yahochanan]

Great job as always Quinn! Food for thought: I recently picked up a right angle head for my dremel while having to cut & deburr a plastic cavity. Worked really well. You might consider using this for getting in to deburr with a small chamfer tool. That is if it all fits. 😉

[alexvonbosse]

Very interesting assignment! You did an excellent job on this project as well as narrating your steps as you progressed, especially while using your DRO! I'm still learning some of the hidden features of my DRO since the manual's translation from its original language leaves a lot to be desired!
Thanks for sharing and keep up the great work!

Well done, always good to have happy robots..
One thing on boring head technique.
And it's fine to use a dial gauge to double check the adjustment, using a disc end preferably...
But, I just do not trust the clamping, especially in older heads, to not let the cutter/dovetail combo slide out to the tolerance of the adjustment thread. Especially with larger diameter holes and heavier/longer boring bars. I have had this happen, thankfully not on the final cut!
The technique I've adopted is to turn the dial past the desired setting more than the slap of the thread then drag it back, with clamping fairly tight, to what I want as the next cut.
This ensures the setting doesn't change.
This may be an 'ahaa' moment re inconsistent size, cut or even bell mouthing of the hole.
Hope this helps someone.
