Humm. I’d be worried what would happen if the puck jams up between the tool and the chuck/workpiece.

If you peck with the annular cutter it breaks the chips and can mitigate the birds nest.

Nice to see a different hand press as the ones I’m used to working are from Victorian times which still work just as well as they did when they were made and have really stood the test of time. I worked as a tool setter for 2 and half years before I moved into tool making for the uks oldest running privately owned manufacturing company which has held 11 royal warrants for the last 11 monarchs. I watch you on my break times from time to time and I love the content 👍🏽

would it be possible to put a tap on the drain? I'm asking as i have the same model lathe😀

You should look into a quality diamond grinding wheel. One of my favorite shop tools is a very expensive eyeglass grinder that was damaged, but the motor and grinder were (and are) still running perfectly. Ideal for tool steel or carbide and it only cost me $30. The motor alone would have been hundreds. Used Lapidary equipment is also great for sharpening.

This went so much better than his brain surgery video...

Great job on a fairly commonplace tool. We shared this video on our homemade tools forum last week 😎

Thanks

pi is quite close to 22/7, relative error 0.0004. Do you have any gear pair for the lathe that gives 22/7 ratio? Like, 2 x 55/35

I’ve used annular cutters on aluminum tube for a trailer cross bar and they work well.

I wonder if using some Lucas Pure Synthetic Oil Stabilizer, available at Supercheap, would help calm down that gear noise?

Interesting idea , thanks 😊 What grit is/are needed to grind and finish these HSS shanks ? …

i would add lime to the mix of charcoal. it produces carbon dioxide at ~850 degrees and at ~800 degrees carbon monoxide becomes the prodominant product in the reaction between carbon dioxide and carbon.

I jut found your channel and wa wondering.... what i that accordian looking cover you have made of. do you have the pec on it.... I am trying to go through your ch but figured I would ask.

I loved this, thanks so much for sharing mate 🤩

Where was the hacksaw?

with skills like this you could give yourself a real trepanation np. they have special tools and you could make them. new episode ?

Good on ya mate, looks good

После закалки не стал отпуск делать ?

okay but you have a spring loaded quill - Why dont you just chuck up a tap and push it into a hole and let the tap do the cutting while the quil gives you spring compensation and just reverse the tap out again - I've done 1000's (litterally) of taped holes that way

I'm way ahead of you because I made a cutter like that out of a big end mill and it worked awesome. I used it to a 11 1/4" Brake disc out of 1/4 " Stainless Steel and also cut out the 4" center of it.

A lathe is just a mill turned on it's side with the z axis swapped.

Mate - another great video, thanks! Your lathe sounds terrible!

the knifemaker in me is cringing at the colours on the tooling your making on the grinder😅

You talk funny

Ive been a subscriber for a while now and im stunned you never thought to use annular cutters!

annular cutter could be a good alternative to a hole saw

13:25 that runout should be measured, not observed :) And it should be measured after the retaining screws are tighten :) This way.. its just your best wishes, nothing else Of course.. it wil work cos anual cutter tend to self center if it's not realy badly off center, but...

The reason that cutter is doing so well is it's the bit used in a Magnetic Drill that's used to drill large holes in steel plate/I-Beams... This type of work is EXACTLY what that bit is designed for...

So in essence, you've just made a different type of Hole Saw... But in this case, you spin the material, not the cutter...

Tip for hole saws on deeper holes, drill a small hole along the circumference of the cut on the side that is the waste part. Main trouble hole saws have is clearing chips, so a few holes allows for better evacuation

this is really helpful! thanks

1:13 - or you are using it wrong ) to cut a thick material with a hole saw you need to drill some holes first (about 3) which will slightly intersect the line of cut. those holes are needed to clear the chips from a hole saw blade.

HA I’m watching this before taking my adhd meds and I absolutely misheard “a 38-ish mm hole” as “a 38 inch mm hole” I rewatched those 5 seconds like four times

Thank you for that video.

Two words, bud. Mist Coolant.

thanx for your opinion, that was great help, Im somewhat a newbie. If I can, I'd rather buy what works Than have had wasted money by trying to save

Trepanning mild steel i a bi***. I make trepanning tools from soldered carbide lathe tools, works better for me. and i dont bother under 60mm holes :D

It's time to make an endmill holder for the tailstock. Then you will not have so many folks yelling about an endmill in a drill chuck.🤣

I have the same lathe, and it sounds exactly like yours, ,what oil are you using in the gearbox’s?

AWESOME!

Surface Finish - Try pulling out more. You have to clear the chips. You also reduce the heat too. Also try a reamer at the end.

Suggest some travel sickness pills before putting someone in the lathe for their trepanning. 🤪

With the money and time spent on upgrades- you could have got a real mill. 😁

I use annular cutters when drilling truck chassis’s. When they become dull we just send them off to our tool grinder guy in Sydney. A fraction of the cost of replacement and good as new..

Ever since seeing annular cutters on Adam Savage's Tested channel I've been looking forward to seeing annular cutters used for cutting holes in other heavy-duty machine-based cutting operations. :)

I love that you discovered annular cutters. I have to admit being disappointed that you used an angle grinder instead of the hacksaw with a diamond grit blade on that HSS. Joking of course! Love your content!!!

Minimizing front rake on the tool might also help with strength and rigidity. Only need like 7deg.

your surface warped because when u removed the millscale from your part u reliefed a lot of tension wich was introduced when it was drawn out of the steelmill.

Nice video. Thanks for sharing. 👍
