More and more Dave, I am amazed by the sheer scale of the work you do... some of these tools are soooo long! That big spider sure is useful, though remember seeing it, or similar, before. You are a man with a mission and enviable skills... experience cannot be under valued ever. ATB.
Mr Wilks, I'm so glad that they see the value in your abilities. Putting you on the repair of those tools is a compliment. If I had a shop, I'd put the best man I had, on those tools. Thanks for taking the time to film your work. It is a blast to watch.👍👍👍😷🍻
A couple of months ago I had no idea what trepanning was or why it was done. Now I am gaining an understanding of the process thanks to David's videos. I doubt that as a Maintenance Carpenter and sometimes welder I will ever need to trepann anything, but working in a large private school you just never know when some little gem of knowledge will come in handy and the other guys will ask where I learned to do something.
Great to see someone make it look effortless David. If you wan`t to get rid of your tea cup stand, shall we say a couple of bags of your favourite tea bags? lol
I've done a lot of things on my lathes but I have never towed anything with the carriage using a tow strap. You could probably pull a car out of the ditch with the set up you had. Ken
I used a Huron in my previous workplace. Decent machine, but awkward at times, (thanks to a lack of maintenance) malfunct on the Y axis, full of swarf from a lack of cleaning done by others and a dead X axis on its DRO. I preferred their Ajax mill but that machine died on me and they had a Bridgeport lookalike that I couldn't operate because of a lack of light in that area. I appreciated how much I learned in that firm, but the lack of care and cleaning done was frustrating. Only me and a toolmaker (who used to work in Cottam and Brookes) would clean up after ourselves. He was a good friend and a great mentor and engineer.
Bloody hell Dave, if that's coffee in the big SportsDirect mug, you must be working like crazy after drinking it all. I've been doing myself some tea in it back in the days and it was lasting half a day.
I am wondering why machining toward the tailstock provides such an improved finish on the material turned. Could you chime in with your views at to why that happens ??? Thanks David for your opinion Sir. Good day and peace to you too. VF
It loads up the rotating centre of you cut away from centre doing cuts like David is, the material can come away from the rotating centre. It barely had to move away for it to start vibrating.
David didn't you use trangular tips? Is there a particular resone you are now using trigon? Great video again. Thanks. 👍 All the best to you and yours. 🔨🔧🔩
G day Dave, hope all is going well for you and family, does John Smith taste better now that you can walk out at nock of time ! all the best and stay safe 👍 🍺🍺
Great video Did you find someone new to sort machine the cartridges for you or go back to your old supplier( after the last bad batch ) Or is this someone else problem to sort now your on the payroll. Stay safe 👍
David, what is the way to determine whether the rebate on the trepanning tool is for the inside or outside cutter? I am watching on my phone so if there is a slight difference between the two then I can't pick it up visually. The rebates seem to be the same and the remaining metal near the inside face seems awfully thin but it still holds.
The lengths and diameters these things can be used to do is impressive. What’s vibrating in the background when you’re turning that bar down? And also this probably a stupid question but what defines the inner and outer insert location? To me the trepanning tools look the same on both sides? Watch you don’t damage the Huron with that heavy use..
Love the concept, but Don t you think it would be better and safer, to do this by, first mounting the work in a bigger casing, that has threaded extensions and chain sprockets, holder work with large stugs, ever 3 feet, and the attaching this to the spindle without chuck, isn't all that weight hard on the jaws...?
Love your videos and very impressed with your skill. I do have a question that is puzzling me. I have always been told that turning should be done toward the headstock because the thrust bearings are on the chuck side of the headstock. The few lathes I have had apart had massive thrust bearings on the chuck side and minimal ones for adjustment on the other side. Are your lathes built to cut away from the headstock, taking up the load with the tail stock, or something I am unaware of?
Love the work you do David/ IMO, the finest Machinist on YT. Will never forget all the great advice you gave me as a novice machinist....TY! ~Richard
It's reassuring that there are still a few people in this benighted country who can actually do something.

i second that
Thanks for posting Dave.
Interesting work. Great vids. Thanks David
You´re an excellent craftsman David, hats off......always a pleasure to watch and a lot to learn...thanks for that

Always good to see your jobs happen.
That shop must really be enjoying having you on the books,
all those trapaning tool rebuilds....
Yay more Bridgeport work I cannot wait for mine to arrive next week 😃
Great video Dave . Cheers .

Love watching a professional at his craft
I'm amazed at the sheer size of the work you do!!!!!!!
Thanks for sharing, another great video.
brilliant Dave love seeing work like this
I've done a lot of things on my lathes but I have never towed anything with the carriage using a tow strap. You could probably pull a car out of the ditch with the set up you had. Ken
Thank you David..
When the video first started with turning the bar the new steals. I thought bugger that’s as loud as my old Colchester.

The coffee cup looks right at home 😂 might be room to put your hat and lunchbox next to it.
Enjoyed that cheers Dave.

Hola David una gran herramienta y un buen operario My favorite channel and the best trepanning men.I don't speak english.sorry saludos
Lovely work David~
Nice video , thanks for sharing .👍
Bridgeport mills are superb, when you can get one of them for reasonable money and get very good results out of them 👍 take it easy pal
Forgot to ask, how far back has this method of machining been used ??? Are you aware of a time frame???? Thanks VF

Ηello David why you don't like the cnmg tooling? I know you have addressed this before but i can't seem to find the video.
Now that is a BIG BOY.
G day Dave, hope all is going well for you and family, does John Smith taste better now that you can walk out at nock of time ! all the best and stay safe 👍 🍺🍺
Do you have multiple steady rests under work for support, it's not really all chuck jaws is it?
Great video
Did you find someone new to sort machine the cartridges for you or go back to your old supplier( after the last bad batch )
Or is this someone else problem to sort now your on the payroll.
Stay safe
👍

What an artist
as a shop machinist your hourly rate here 70 dollars, that is as a employee, as an employer charge out 200 hour.
A true Master!
How many support pads do you use on a trepanning tool?
Good work dave i need left and right cartridges can you help me

Watch you don’t damage the Huron with that heavy use..
Sandvik has a good overview

Would really be a treat to have you and AvE in a vidjayo
...and you too from one lathe turner to another. Cheers
Dear David,
I would like to get yoir quote for a custom boring tool.
How can I contact you to discuss details and possibilities,
Interesting engineering!

David is this your new job where you work? Or its still your buisness?
This is filmed at the new place. All his machines went to a new home (thankfully) and are back at work doing what they do best!
I guess your shop must be almost all big hole punching or that is just what they have you do?
Have fun with that super duplex stuff, in my experience that is nasty as heck
did you say 60?
you need to use a rule 😂😂 i just use me eye👻 nice video tho 🙇♂️
.....'n it takes two Bridge Ports to do it.......
what is the difference between tow years ago and what you are showing now. do you now work for someone else
Buy a new indicator boss...
Drink pints. :)
First...
