Boring out cylinders today! 

I was a machinist before a disability and listening to Dragonman, he would make a great teacher for younger people wanting to learn a trade.

Old schoolers have known Dragonman since his ads in the old biker mags from back in the day. He's been badass a long time dudes.

I love when he does these videos. I never tire of watching him demonstrate and tour his shop. You could spend years following him around the shop day in and day out and still learn something new every day.

What is cool is the Dragon is having a ball. It's fun watching.

You remind me a lot of my dad. Strong work ethic and a real Self Starter

I just love this guy and have since reading good ol' Street Chopper back in the '70s way up in northern Sweden during dark winter nights when dreams were made. 👍 - Thanks Dragonman!

A very well equipped work shop with someone who knows what he’s doing, thanks very much.

Machine shops I’ve used you drop off a cylinder on Monday and ur lucky to get it a week later.

"If you snooze you lose" I like that one!

man this video is incredible im blown away i was looking for dirtbike broing but i also got shovels cant beleive i found this! incredible

Learned more from this video that 8 previous ones by others.

Look at that workshop, look at all those machines and tools!

You're a cool old guy with a badass shop. Love it.

I hope one of his family members learns this because it's a lost art and this knowledge is going away with these guys.. best service and job I seen on harley engines

my goal is to have a shop like that one day! awesome to know how to do all that stuff!

I love your work ethic! young gen has nothing on the old timers.

This guy is the real deal.

You want to make money... You got to work! Hell yeah brother!

Amazing equipment and skills to match... VERY VERY COOL...

its great to see a guy like him and the age he is with full of energy and willing to show things to others awesome

Dragonman i didn't even know this was your main career, i didn't think i could respect someone as much as i could respect you(over the internet). I see why and how you really got your name now. You're a very wise man thanks so much for all these range of videos. Good luck with the upcoming winter you've got a nice gig. I work outside cutting/welding on asphalt plants that are shut down for the winter in the north east. I respect your craft youra master

If I EVER need any harley machine work it's going to you dragon man!!

Your not boring at all Dragonman:)...love your shop set up...all those tools and machines tell me you have been doing this a longggg time..

Really good video compared to some of the boring video's I've seen on RU-vid. I had no idea you could bore a cylinder the way you did on the first machine. Very fast!

That's a lot of 'how not to do it" in 1 video

A buddy of mine says NEVER practice on your own stuff. LOL

Incredible shop!!

You are never boring to me, Mel! I am really enjoying your machine shop videos! Thanks for sharing! Bayswater Blvd.

this is the great example of efficiency in working, no time wasting, everything setup ready to go pretty much... grab it, set it, get it done... next! Yeah, just by chance discovered your video, you're a natural teacher that's for sure, we all wish we had shop foremen that were as good as you to show us the ropes. And love your shop, that's a dream shop for me, small, got literally everything it looks like... great place. Livin' the life it looks like (and you sounds like you're from my neck of the woods (NYC), though you've been in Colorado for awhile I think?)

Nice. Ive done dirt bike cylinders for 30 years. Its a dying art with these new coatings in the cylinders. Ive sleeved a million cylinders on my VW bug cylinder machine and the lathe.. It would do the little 80 cylinders too. Ive got piston manufacture stickers on my garage door so thick I think its holding the door together..lol

You have a great setup, Mel. I was a machinist, but I didn't do automotive type machining. I made all types of parts for industrial applications. The shop I worked for had a similar honing machine, Bridgeport milling machines, and all types of milling and turning machines. We used the very same dial bore gauges you have and that's how I know you have a great machine shop for motorcycle engine repair.

Awesome video! I feel that after watching your video I have gained some knowledge about boring cylinders. You are well organized and provide a valuable service with a fast turnaround. I may need your services.

Absolute Legend. You make that look so easy but Skill always makes work look easy I’m sure I could cock it up. Thank you for your knowledge

Old school experience just can't be beat. I hope you have some apprentices to carry on your wisdom and ethics. (Something that's sorely lacking now-a-day.) In your 13 minute vid I learned a few things I was never aware of. Thank you for your time, Sir.

Dragon Man: You see that? Me: Yes sir Mr. Dragon man sir!

Your shop is awesome!

So awesome! What a great shop

I wish we had a shop in Minnesota like this

What a great video and beautiful operation 👍 👍 👍

I’ve always said i’ll never work for anyone but myself.... but damn would i love to work for and learn from you!

what an amazingly clear video; ** thank you, sir**

Your an educator. Thanks

Hello I really enjoyed your post. Thanks again for sharing what you know.😅

This is amazing. I love your work. Thanks for posting this video.

Love your shop, I can see how you get things done so quickly. I've always loved to do machine work.

You are great.we dont have people so skilled like you in our vicinity any more, we once had them, now the generation is lazy and is full of only money grabbers. So happy to see you brother.Iam fighting for the ban of fuel injection systems and electric pumps together with the hot spark ignition system all governed by the ECM.As all this rubbish is responsible for car fires.

Nice video, love seeing behind the curtain...

still nice to watch. Hope all is well.

Nice work dragon.in Africa we need those machines . thanks

Another great video Mel, thanks for sharing...keep up the hard work! Stay awesome!

Brother you can tell you have been doing that for a long time 😊 because you knew when to stop well done 👏

Thank you,Sir

knowledgeable gent a real treat.

Awesome shop.........love the setup.

Pretty cool boss!

They don't make them like you anymore , your one of the last dinosaures / dragons; they broke the mold and kicked the mold makers ass !

Thanks for the video I'm trying to learn some auto machine work and these videos really help.

My husband loves you.

Very impressive. In every way. Thank You

You are blessed my friend

This guy is Gold!!

I’m a locomotive mechanic by trade but always had a interest in this kind of work.

Very well done.

I Love this video. It’s my 2nd time now to watch it. I also bore out cylinders.

VERY IMPRESSIVE!!!!

You rule dude and your machine shop is cool as fuck!!

Great setup

Id love to meet this legend. Motorcycles, weapon's my lord thas my dream.

Very impressive video. I’m glad I found this channel. Old School 👍👍

When i was boring a wide array of engines the customers with the Harleys were the worst some would bring the barrels back and say it has to much clearance look the piston wobbles so then you have to explain to them that the piston is not round it may look round but it is not, the clearance is measured at its largest point which is at the bottom of the skirt 90 degrees to the gudgeon pin. The harley guys always thought they knew best.

Guy dose it all‼️🫡🇺🇸

how does this guy find the time do all these things? its almost as if there multiples of him.

Great shoppe...! I'll remember...

Amazing, simply Amazing. Kenny from Brooklyn!

Thanks for Sharing!

That was really, really interesting and informative. Subscribed

YOU CANT IMPROVISE EXPERIENCE !!!!! MASTER CRAFTMAN

What don't you do... youre such an old fashioned guy who gets everything on his own

Nice Work!!

Wow, what a great video!

Very good spirited video, thank you!

Very Cool!

Nice shop.wow.

Very cool 😎 brother 👌

Awesome you have inspired me

i don't know when the last time you weighed a set of pistons, but those junky cast pistons weigh a lot more than a nice set of forged pistons. I know, I've been doing this for 30+ years and still doing it today. After you start cutting the cylinders down you have then thrown off the intake manifold and pushrod length. Then you still don't have much more compression because those junky cast pistons seldom ever oil out to what they are advertised for also. I know. I do that quite often too. Then you end up with cylinders that are too short and you can throw them in the trash because when you put a good set of pistons in them there will not be enough length for the top piston ring. Also the 100 grit roughing stones should only be used to straighten out the cylinder and the 280 stones should take out the last .005" so you have a nice finish, not a rough finish.

Learned a lot from this video. Thanks for posting.

This Guy is the best

How square is your setup on that Sunnen or is there a little give for the bore to find itself on the mandrel for squareness? Cheeers from Canada.

Dragon man,you seem like a pretty cool guy.good job.

Seems like a fun job we thank u 🍺

Hey that was terrrific Thanks for walking through what a day is like for you.

i like this work

Much appreciated video ! Thanks !

Makes me regret not going to school to be a machinist.

Dragonman's the maan! 👍

Great video.

good work

That was wicked. I have always had questions as to how you center stuff.
