Hey everyone- yes I know there are typos in the metric conversions on this one. I’m sorry, I do my best to catch them all, but it happens sometimes. No need to keep commenting on it. Thank you.

@bostedtap8399 2 года назад

Hi Quinn, Don't worry about the dual units, yes, it reaches more metric only viewers, maybe just add a nominal conversion on screen, EG, 0.0394" = 1.00 mm, or 25.400mm = 1.000" (exact). Being 60 years young, in the UK we changed to metric during my junior school, in fact we had to amend our text books 📚 . As per usual, excellent work and techniques. Best regards John Quinn.

@MrZX1206 2 года назад

The AC motor 9x20 lathes have a secondary pulley with a built in clutch that allows lower speeds. With some replacement parts from the Grizzly 9x20, you could gain slower RPMs and greater torque. The bump out way the DC motor is mounted might need to be reengineered since the AC motor mounting plate is flat and the AC motor pulley has a toothed belt to power the secondary pulley. At some point I’d like to make a custom set of pulleys with a larger diameter driven pulley and a longer belt for my AC lathe and DC mini-mill.

@UncleKennysPlace 2 года назад

Slowly heating that flywheel to ~300°F in the oven would be fine, just ramp it up in four or five steps. Forty years ago I used Mom's oven to put in valve guides. Note to self: clean off all oil if using own oven.

@Infrared73 2 года назад

Would both not help? I was wondering why not just increase the casting to 30c to increase the difference in temperature.

@johnmcclain3887 2 года назад

Do I suspect you missed some oil once? Been doing the same most of forty plus years.

@JBLewis 2 года назад

We used to do the same thing with VW Rabbit and Golf rear brake drums. Toss the bearing races in the freezer the night before, and then slowly bring the new drums up to temp in the oven. With the big temp differential, the bearing races would just drop right in.

@trebushett2079 2 года назад

With thin bushings, make an assembly mandrel, this also holds the low temperature of the bush for longer and allows you to better assess vertical alignment. Also, add a lead-in to the bush end, which may be done by turning or even a file and emery cloth. It is also possible to use the drill press as an assembly tool; simply make the assembly mandrel to fit the drill chuck. Freezing the bush and heating the flywheel, would be a good idea, too. Oh, and I almost forget to say, for interference fitting, junk the loctite, it's counterproductive; heat generated by a cold press-fit job, will set-off all but the slowest activating loctite, and if you're using shrink fitting methods, should the bush expand during assembly, will result in a similar outcome. When cold press fitting, a polished entry laed-in is essential, and so is the use of a lubricant for many materials such as stainless steel to stainless steel or soft aluminium, etc. A heavy press-fit for one inch diameter would be in the order of 0.003" to 0.005", and more for things such full size train wheels to their axles. Hope some of this helps.

@jochenreichl796 2 года назад

I'm not an expert machinist, but as a mechanical engineer I also have some insight. I learned a lot from Quinn, but here I also wondered why she used a press fit AND loctite. Also at least a chamfer would have helped starting the parts.

I've had great luck using computer duster upside down as freeze spray. It's the same Di-Tetrafluoroethane mix as in freeze spray except you can get a 3 pack at walmart for a fraction of the price. It can theoretically go lower but I typically see it bottom out around -40C. Not nearly as cold as dry ice and it won't work for all applications but it's far more convenient. I wrap the part in a paper towel then soak it in the spray until it stops evaporating and the paper towel stays wet. Then heat the other end and press them together. Get the part started but leave the paper towel on the part and press it in. This helps keep it cool while pressing and gives you a few more seconds to work with it.

I have been involved with helping to do a couple of shrink fitted bushings at work using dry Ice and was taught that you have a much better chance of success if you chill the shaft going in and heat the bore that its going into. The more temperature difference you have the higher your chances of success will be. Submerging the bore (or the fly wheel in your case) in Boiling water while the shaft is cooling in the dry ice should be sufficient but make sure to dry it well before fitting. I love watching your videos Quinn they are very inspirational and are overflowing with fantastic set up tips and tricks. Thanks heaps.

I have a minilathe (vm290) and i changed the belts to a HTD-5m belt and pulley. I also changed the motor with a 2kw servo (6 pole) and it made all the wonders. It has almost 100 Nm of torque peak and 20 continuous. If i use the larger pulley it has 22Nm peak and 3000 rpm. Its really an upgrade worth considering. Also I highly recommend filling a bottle with coolant (i use cimcool) and putting it 1 meter above your lathe and having a valve on it. You only need a few drops and it really does make a difference.

@JeremyMakesThings 2 года назад

I once needed to ream a 1” hole, so I bought a 1” reamer, only to realize that I had no way to hold a shank that big on my mill, not to mention I didn’t have the vertical clearance for it. I eventually resorted to holding the shank with vise grips and using it as a hand reamer. It was tedious and it worked, but kind of tore up the shank…wait! That means the shank is soft. Put it between centers on the lathe, turned it down, cut it off and now it does what I need. I later bought a large number of second hand reamers that all had the shanks turned down like this. For large reamers on small tools, it’s a modification that’s worth considering.

@johnsherborne3245 2 года назад

Some Dry ice and acetone cooled steels can exhibit interesting properties.I recall in my metallurgy days we cooled an Charpey notch sensitivity test bar in dry ice, so about -80. Other temperature tests the bar broke roughly according to plan, but wow, -80 really was dramatic., the steel shattered like a toughened windscreen, we struggled to even find the remains.

@johnsherborne3245 2 года назад

@@Murgoh I gather that during WW2 American built Liberty boats used welded steel a lot for the hull plating, which was novel.. this had been done quite successfully till then, but a number sank or started to break up. Investigation showed that the steel plate had more carbon than was ideal and the heat of the weld precipitated carbide a short way from the weld. The problem hadn’t occurred before as the ships were being routed through arctic waters and the low temperature was enough to break the ships. A similar thing happens with welding stainless steel if the carbon is at all present, except that it’s chrome carbide that causes the brittleness.

Hi Quinn, that’s a decent milestone to reach and the engine is looking good. I am not preaching so please do not be offended by my next comment, as no offense is intended. I watch many American channels because there are a lot of good ones, far more than I can find in the UK. I have seen all kinds of ways people attach bearings, by heating with a gas torch which I no like, freezing a spindle but that never seems to work. I am a retired Marine engineer having spent my entire life at sea and fitted literally hundreds of bearings. This method has never failed me. Heat a bearing or whatever needs fitting in a bath of oil 80 to 9o deg C (144 to 162 deg f) and the bearing or fixture slides on in one beautiful moment. I think this method would have worked well for your flywheel. Having said that, you managed as you always do, to rectify any issues you have and completed the project satisfactory. I cannot understand why I have never seen an American channel using this method. A can with some oil in and a kettle element fitted, and a thermometer works just fine. Thank you for your update on this large steam engine, I look forward to each and every episode you produce. Kind regards from England UK.

I do a lot of shrink fitting and I almost always make some sort of guide. For thin bearing liners they are mandatory. I typically make a two part arrangement where the sleeve is sitting on a lower mandrel that is cooled with the sleeve and the hub ride on a second guide with a pilot that will enter a hole in the lower sleeve. I just fitted parts with 2.8mil fit on 1.375 diameter where the sleeve was only 0.050 thick. *made three practice pieces. messed one up by being to slow.

Dear Quinn, Inspiring, as usual ! I live in Japan so checked out a few websites, and the 60 degree v belts are easy to find here too. They are called "3M shape". Been waiting on a new lathe for a while now as there has apparently been worldwide delays in supply, possibly because of the semi-conductor shortage. Anyway, my Japan version of the Sieg SC4 has arrived at the supplier so hoping to receive it in a couple of weeks. The supplier dismantles, cleans, aligns and lubricates the machine before shipping it on to the customer. I have a workshop full of woodworking equipment, but now going to work with metal ! Hope to build a separate metal working shop sometime soon. Keep up the good work; you have a least one die hard fan in Japan! Bob

I just spent half an hour looking at where to buy liquid nitrogen, and pricing dewars to store it in. Apparently tire shops are the secret go-to supplier for liquid nitrogen, and Costco sometimes has dewars for sale.

Careful- tire shops only have compressed gaseous nitrogen which is for filling tires and isn’t cold. For cryogenic liquid nitrogen you have to go to a specialist supplier

Thank you. You made my day. Yesterday I was looking for your video. Not seeing it, I then realized it was Friday. I was having a bad day. I really enjoy your videos. Thank you very much.

Good problem solving skills Good information great tutorial skills thank you for helping me find my lost inspiration

@raymitchell9736 2 года назад

This was a great video, it had its share of problem solving and technical difficulties that you handled so well... I think this one has to be one of your best videos showing that process. Now that I've seen this video, I'll bet that you have several contingency plans but you don't explain all of those if plan-A (of B) goes well, but it's that very thing of forward thinking that I find super impressive... I know this isn't something that is natural or "common sense), it comes with experience... and I mean... lots of experience. Great Job.

Anyone else interested in seeing Quinn's pinball machine side-projects? Don't get me wrong, I'm loving the steam engine and machine tools content, but I'm not gonna say I wouldn't also enjoy some pinball machines and a bit of the electromechanical wizardry that goes into them too!

Great save. Thanks for the video.

@jameschaffe694 2 года назад

Interesting that you finished the outside of the bush before even roughing the bore. I always rough the OD and bore then finish them after, this saves any spring/relaxing/distortion in the material.

Some asian lathes have 2 step reduction pulleys, but increasingly the ones with DC motors only have one. One reason I ended up buying mine (Paramount Browns FI550) with a 1 phase AC motor with 2 sets of pyramid pulleys. Swap out the 1 phase with a 3 ph and VFD, gives you best of both worlds.

You oughta do some videos about your pinball machine work!

Good tip on where to indicate on the part while centering. I would not have expected the hole in the center to dance around as it did

@carlsmith6613 2 года назад

most excellent, quinn...! looking forward to future videos on this project...

@Just1GuyMetalworks 2 года назад

Well done, Quinn 😊. Big things on small machines certainly poses it's set of challenges. Maybe a future project for you, it looked like there might be room for a counter pulley near your drive there. A relatively cheap and effective way to get those low rpms if you should ever need them 😊. In any case, great video! I'm gonna have to try making one of those engines I think 😁. Cheers!

@howder1951 2 года назад

Great video Quinn. with shrink fits, the bigger the easier, because there is so little mass to transfer the heat from shaft to bush you have to be lightening fast, so what you did is quite difficult. Enjoyed the video, cheers!

You are a very smart person! I love how you describe what you are doing it's very descriptive and easy to understand as an engineer should. All this makes me want to run out to my garage shop and fire up my Jet 12" X 36" lathe and Grizzly mill and finish my projects that I have sitting around waiting for me! I really should get off this computer!!!!
