You always explain your work well Andy , your explanation is the same as the visual,, nice camera work Tonya , you have a great understanding of the work 👍,fabulous art
Very informative. Harleys need a variety of special reamers, usually .001" over normal. I may look at trying this with some old reamers. Thanks for the info!
Your wife's a champ for filming this. Subscribed. Thank you. Ive got a Harig and a surface grinder. Looking to undersize a 12mm reamer. How far you reckon I can go before I need to re-grind the relief? A few thou off the Radius? Any rules of thumb?
Thanks, she's a gem all right! You can get away with way more than you would think. A tool will still work with the tiniest sliver of a flute but remember as the depth of the flute decreases your vigilance in clearing the chips has to increase accordingly. Thanks for watching!
Thanks for the comment! Re end mill end gash, I go over it some in the video in this link. ruclips.net/video/nuDmsspn94g/видео.html Please let me know if this answers all your questions. Cheers
Thank you for showing this stuff, I appreciate the effort it takes to make understanding this stuff possible. Have you made a video about Center Drills?
A simple and very effective reamer can be made from ground high carbon steel, commonly known as "silver steel". Machine to the diameter required, machine or grind off to a long flat oval cutting edge, length about 4 times the diameter. Harden and temper to a light straw colour. Sharpen on an oilstone.
Great video as usual, newbie question, when you dressed the wheel the table was set to your 1/2 thou angle so wouldn’t that put the same angle on the wheel? I’m assuming that’s deliberate, does that give a clearance angle for the grinding so only a small bit of the wheel is actually removing material? If you dressed the wheel before changing the table angle would that make any difference or am I overthinking as usual? 😂 Thanks!
Great question! I don't think it's possible to "over think" when you're talking about tapers because there's a lot going on and everything affects everything else. To answer your question, I had the upper mounting surface of my table set at an angle with my diamond dresser mounted to it but the dressers path is determined by the table ways and they always run exactly orthogonal to the saddle ways so my wheel was dressed at 0-degrees and the entire surface of the wheel was in contact during grinding. So to sum it up regardless of the table angle you will get a 0-degree dressing on the wheel. If you actually want an angle on the face of your wheel you would offset your wheel spindle to the desired angle, dress the wheel, return your spindle to 0-degrees or dial it 0 to your table ways and then you could proceed to grind the angle. Hope that makes sense Cheers!
Hello Lappe Mountain, again really enjoying the videos. They are exceptional. Would it be possible to add to the video queue how to change the angle of an angle reamer? I need a 4° taper reamer of a specific start and end size to fit a blind hole. I have plenty of 3° and 5° taper reamers I would like to try and convert to what I need. Is this possible? If so a video would be greatly appreciated! Thank you again. -term
Hey term. Consider the topic added to the que! Spoiler alert! to make a 4' you would want to start with the 5' not the 3' so that's the example I will do. Thanks for the comment! Cheers!
I'm wondering if the same thing could be achieved with a Darex E90 endmill sharpener? I happen to own one of those and never thought about sharpening reamers with it if I needed to.
I hadn't heard of that machine before so I took a quick look at it and it looks like it would work for putting the clearance angles on but I'm struggling to see how you would be able to grind the lands with it. Thanks for watching and commenting!
@@Lappemountainliving To grind the land, you engage a lever in front of the tool which drops the spindle down roughly and inch. So because the spindle/work is sitting lower then the center of the wheel, it's in the right spot for griding a land.
I believe a "land" can have different meanings depending on the tool being discussed. I'm curious if we're both using the word land in the same way in this discussion. When talking about the land on a strait reamer I'm referring to the cylindrical area between the tooth face and the clearance angle. Can you clarify what feature it is that you're referring to?
Hahaha, Good eye! It's actually a raptor 60 with a 70 in it. I slowly worked my way up to it in about 2008 after mangling multiple little electric jobs
I'm really enjoying your tool grinding videos! Thanks for sharing your knowledge.
Glad you like them! Thanks for watching!
Excellently explained, loved the video, Thanks so much.
Glad you enjoyed! Thanks for watching!
Really good video! It's so hard to find good toll & cutter grinder videos. Thank you.
Thank you and thanks for watching

Many thanks Kathy! You're the best!
thanks for adding the metric overlays, this is so helpful for following along
Glad it was helpful!
Great video! I've always wondered how I could do this in my little home shop. With some creativity, I just might be able to. Thanks for sharing!
Glad it was helpful!
Good audio, just right dialogue, and answering the questions in the viewer's head!
Awesome! Thanks!

Great info on grinding reamers.
Could you do a video on accurately gashing the center cut on 4 flute end mills using your KO Lee?
Thanks for the comment!
Re end mill end gash, I go over it some in the video in this link.

That makes perfect sense! Thanks! More to think about!
Hi Guys, Thank you SOOOOOOOOOOOOOOOO much. ♥ to you both. Cheers, Davo from Aus
Cheers to you Davo! Happy grinding!

@@Lappemountainliving brilliant thank you!
Howdy
How to custom angle a tapered reamer is coming out tomorrow!
Hope it helps.

@Lappemountainliving Amazing! Thank you.
Would like to see your sharpening of and adjustable reamer blade.
That's a great idea! I'll put it on the list. Thanks for watching!

Is that a Raptor 90 heli in the background? I've been flying R30 & R50 for about 24 years. I never got up to the 90 size.

Do you not have to redo the leedin chamfer? Just asking, i don’t know anything about machining.
You could if it was dull. It's not automatically required in the re-sizing process
nice
Thanks
Enjoyed a lot! Thanks! Sub.
