This page has some good info on drill sharpening.

I purchased all the items to make one of these a while back but life got busy. Now I see you can partially build one of these with 3D printed parts.
Guess I need to get started.

Yep - tool sharpening topics can suck you into a lot of different rabbit holes.
I've seen that you also live in Burlington. I just sent you a Private Message with my contact info. If you are interested, we could maybe meet face-to-face.
Intetesting thread. Respect to those of you that are excited by these machines. If one has a busy shop or does high volume drilling or perhaps like the prescision it makes sense.
No doubt he drill grinders are good to have but I dont drill that much any more to warrant the expense, its also a thing that takes up a bit more space as I look down the road and slowly downsize.
A thing thats very important to me is to not support China and have my $$ flow that way. They are not our friends. I would never buy a Vevor anything or from Temu.
Less than 5% of anything in my shop is from mainland China.
Best to you all

Ya, I totally get this point of view. But I feel I am between a rock and a hard place when it comes to this. These days most often there is either no affordable alternative or no alternative at all.
Better pray that the day never comes when there are no alternatives at all. The very next day - absolutely everything will be priced like solid gold.....

Just wait till the sky hi tariffs and trade wars begin! I worry that your scenario is just around the corner!

I ready everything on that site, I added it to my todo list, but I can't build that for what little I spent on the vevor.This page has some good info on drill sharpening.

I am still going to make a precision grinder but now the need is not so urgent

If the US places high tarrifs the chinese will respond with lower prices both in the US and other nations to increase sales.
US consumers will go nuts too... cheap outweighs "made in the USA patriotism" every time.

Have you tried these yet in your 13B?I picked up the MR-13b model a few months a go but really wanted the expensive VEVOR MR-20G
I had a good look at it and figured its an identical machine function wise and was only missing another collet holder and a few oversize er 20 and 25 collets ( along with spaces in the front to store them) ..... so I found them and ordered them.
er25 collet chuck oversize er20 and er25 collets

The only other thing I could think of adding was the holder from the MR-13a which allows a different point to be ground in, as per Mr Pete's videos on the matter.
oh and while you are at it get some collet holders to print
Gridfinity holder
Free Standing model
I'll order them regardless because they add functionality I need
Since I am considering the Vevor, I decided to waste my time watching Mr Pete's video. Yes, I wasted my time. Again. There are a few things he said that I didn't agree with. Especially grinding the tip off to facilitate taking a deeper grind. But also his comments about split points. Maybe we can discuss these issues together with your build when we get there.

Whats to discuss? Seems to me the consensus is split points are better unless you are tied to grinding by hand. All the more reason to get a machine like the model A that can do split points accurately and well.

Judging by Youtube videos I've watched there is very little wear and should not be an issue in a hobby shop. Commercial production shops might be another matter.

I dont see the fundamental difference between split pointing and web thinning as Lyle demonstrates the machines. I also think that IF I wanted to be really anal I could mod the 13B to do the split point too.
I had the same feelings, and IMO web thinning is just another different method to create a split point. I stand to be corrected, but the 13B offers more flexibility.
Still all his videos did is make me feel better about my purchase, because I can't come close to this with hand grinding. Joint issues and bifocals are not aides to fine grinding.

I think the question "is web thinning just split pointing by another name" merits discussion.
Sadly, Lyle doesn't give us multiple examples of the grinds for comparison. Especially he failed to change the depth of cut on either process. I'd like to see, but not enough to also buy a 13A to perform the comparisons. Maybe Vevor will send me one for free too?
Given the shown geometry of the machines and the different grind points I believe I can get very similar point results between the two machines. I do know that based on other reviews and actual tests that the 13B sharpens better than new.
I won't argue about that. But I am not satisfied just using things. I also need to understand how and why they work. I know I'm not the only one here who is like that. His explanation of how they work is not satisfying to me.
I think they could last a very long time. Especially if they are dressed as needed. But if you intend to use it extensively, I'd get a backup wheel or two. Then again, I have backups for a lot of things that I've never needed so my advice should be suspect.
