Dragonman's Machine Shop Tour

hey everyone welcome back to my Channel today I'm here with my dad Mel Bernstein also known as the dragon man and we're going to tour his machine shop which is the business that you started off initially what like 60 oh yeah 70 years ago no I'm kidding long time ago yeah and and it all started because you built this Dragon bike in in 1967 yeah and if you guys aren't familiar with his Dragon bike it blows Flames out of the mouth eyes light up normally he has two machine guns mounted right here 9mm submachine guns Colts definitely turn some heads when he's driving in town that's right um but Dad go ahead and show us like everything that you do cuz you can pretty much I mean you can rebuild motors and uh what like heads and yeah I work on Holly Davidson Motors and Transmissions 1936 to 99 I've been doing this work for 57 years is in business okay so this is my machine shop Onan operation okay let me take you around here show you what the machines do okay over here we got a seat Master machine that puts nickeloid seats in the Holly Davidson heads this machine here is set up for a jig for every Holly Davidson head to put dual spot plugs in this is my 15 horsepower wave normally we cut down heavy flly wheeels we uh take off 2 and 1/2 3 lb so the motors rev up faster over here this this is my welding area I got three welding machines I can weld every kind of metal uh brass uh aluminum cast iron everything this is my motor stand I made this motor stand probably almost 50 years ago uh every Holly Davis of motor will fit here 1936 to 99 all I have to do is change uh the exhaust pipes I got two twin compressors here see that this really puts out the cfms that's a cubic feet per minute and uh it runs two glass beaing machines and a sand blaster in fact this is the sand blaster last time I asked him to babysit peaches he put peaches in the sand blaster y yeah never again luckily he didn't turn it on but you know that's right would have really scattered yeah that was okay over here I got seven honing machines this one here I used to hone out the rocker bushings this one here is a rebuilding Holly uh Davidson rebuilding Rod uh machine all set up to hone out bushings and races for the Holly Davis and Motors uh all seven machines at up to 120 mandrels top and bottom I have every Mandel from a quarter of an inch 250,000 to 5 1/2 in and uh this is my automatic stroker machine okay I put a cylinder in here right we lock it we we put the top on here and uh we Mark how many thousands of an inch we want take it off uh we push it we lock it see it's locked right now I hit the button I step on a pedal and it goes back and forth and then I open this up and check it every couple of minutes with a 1/10th of a th000 style indicator see that uh within 10 to 12 minutes it hones out uh 10,000 of an inch in any Holly Davidson cylinder cool that's pretty fast okay over here if you want to wash your hands you get them really dirty you just put them in here okay over here at crisscross holders over here use these are Hony machines the H out the valve guides uh for pan head shovel heads Evolutions this is my valve grinding machine all the sound are cut 30 45 60° I can do a three angle valve job in less than 15 minutes in this room here I got all the parts for the Holly Davis and Motors the valves the guides the gaskets the seals the Pistons the Rings everything I need I don't have to order parts every day okay this is my boring bar if I'm going to resleeve a cylinder or bore out the cases for the Big B cylinders 3 and 58 3 and 1116 or 3 and 13 16s I used the boring bar okay over here I made a punch for for every Holly Davidson bearing and bushing okay this is for the main race where the sprocket Chef comes out this is a race if I want to take this out I just put the case here I heat it up a little bit here's the punch that takes out the uh the race and then I take another punch right here and this is the punch that puts the race back in see that and these are heat treated I made these probably almost 50 years ago wow so uh this really helps a lot okay you guys uh you having fun yet don't forget hey don't forget to hit that thumbs up that Bell or And subscribe okay over here I rebuild my own connect garage Holly Davidson connecting rods I don't use any of that Japanese junk taiwang rods these are all Holly Davidson connecting rods real fast look at these uh punches I made this takes the bushings out here we put this in the bushing right here okay we step on the pedal that see and it takes the bushing right out I have another uh punch setup here that puts the bushing back in see when you have all the right equipment everything moves right along I don't need five people helping me okay so uh that's that okay follow me okay over here this machine here cuts the uh brass seats out of the pan heads uh 1948 to 65 and this is a digital readout this shows how deep I'm going these are flutes cut uh 3 to 4,000 smaller than the seat that I put in and that determines the interference press fit okay this machine here after uh let's say uh let's say your spark plug blew out right and you can't get a Hy coil big enough I welded up the whole spark plug hole uh this is set at 45° and uh I drill it out 9/16 14 mm and tap it I could do the whole process in 20 minutes okay over here I use this m machine the most this has 100 memories in it he that this is digital read out 100 memories all I have to do is locate with a dial indicator on the main race on any Holly Davison case and then look at the digital readout and it'll show me where the other holes go wow how's that huh okay this machine here uh I cut down the uh seats see these are uh this uh two flute uh endmill here and that's got call by tips on it uh this is uh for the intake this one's for the exhaust and that'll cut down the seat to the right measurement this is a 90° angle plate I bolt the case right on here I could locate the uh uh motor mount holes after I weld them I could uh let's say the guy pulls out the barrel studs uh this will uh put the holes back in it's digal readout I could put the boring attachment in here bore out the case for the Big B cylinders so each machine does at least five or six different things okay herey come around here let me show you my workbench over here how long have you have most of these machines a lot of them most of them I bought brand new uh almost 60 years here over here I assemble the motors and Transmissions this is an evolution look how nice you wouldn't believe how these motors come in all beat up uh dirty greased out oil leaking all over them and I just did the guys transmission see they send me a note what they want to do return address telephone number they give me a credit card on the phone and uh you know we send it right back to him see this guy here he a tooth came off his gear right there this is the tooth so that was the problem piece of cake are you just going to weld that back oh No I gave him a whole counter show a new okay yeah here the way to tell a good machinist look at the tool boxes see how nice and neat everything is it's where I get my OCD from that's right okay over here this is a 70 and up shovel head yeah look at that that's going out tomorrow look how nice that looks yeah see and I put rags in the flly wheels and I put the whole lower end in a plastic milk rate and this way and I put cardboard around it the plastic milk crate supports the lower end from rubbing through the cardboard and the rag in here stops the flywheels from rotating
