Getting ready for new steamer
« on: December 25, 2021, 02:14:16 pm »
Iím new here so Iíll maybe need a little help posting I did read the rules etc

So Iím looking at a chilerton 4 cylinder horizontal mill steam engine . I should have prepared better. Iíll post the site picture  next post the reason Iíve picked this is I worked in a textile mfg. co. And got to see the insides of the textile mills where  these were popular. Some still had the line shaft hangers in the ceilings.

This engine has enough moving parts to keep me occupied for hours both assembling and operating it. They are not a cheap I donít think Iíve already been in contact with them and they sent a return email in less than a day.  Initially Iíll run it on compressed air . California air compressors makes a super quiet air compressor you can hardly hear run . My son has one at his car shop that is just great. I have an interesting little cubby hole that it will just fit in .
I canít have an open flame boiler and simply have not found an electric one

So I do have materials and a design of my own already sketched out I just found an electric immersion heater on Amazon that has a 1/2Ē npt thread on it. This will fit perfectly in the boiler Iím laying out. It has 4Ē diameter 1/4Ē wall aluminum tank

In order to get on the right track, what are the length wise bundle of tubes called?  At some point I was told they are ď super he tubesĒ seen in big Er engines .  It will have a ring supplemental heater , basically a flat aluminum disc. This will set on something like an RV single burner electric hot plate usually you use a wire ring to keep the aluminum plate away from direct contact the heating coils . I plan on wrapping the boiler with automotive header insulation then a polished stainless steel over wrap for cleaner appearance and to help hold the heat in . There will be a row of 1/4Ē npt ports tapped into the boiler for exit steam, temp, press relief  and possible a couple blank for future use
 pressure , boiler fill with end caps having drain ports  I havenít had much luck finding small gages.   The prices of aluminum and copper have gone ballistic I also have passing interest in turbines. I ordered one on Amazon then found another similar one thatís even better so I ordered that one too. Also found a nice stepper motor to convert to a generator. After watching a video on how to do this I ordered the bridge rectifiers abc appropriate condenser since the engine has both groove and flat belt capability I have spring belt and connectors
I also did a bunch of research on steam oils. I canít find any locally. However I did find a huge paper on castor oil and veggie oils. Castor oil is still used today for break in of aircraft piston engines . It was als used in WW2 as primary lubricant for about anything that needed lubrication. As a boy I used it in model airplane engines and as a result of hot tods I got into nitromethane and alcohol fuels I had ready supplies so many engine got the full load an came apart in spectacular disasters LOL sports and drag racing added to my rep as go for the win no matter what. It cost me my knee an a bunch of teeth. Thatís another day. I also have a small ď dynamoĒ electric motor  that Iíll probably use for som cuter dynamics. I have an idea for a mounting board or floor resembling the polished wood floors if he textile mills. Basically covered with casting resin rather than polished oak. This is down the road a bit  I have some thoughts about mounting in an aluminum case so I can transport it to luncheons and shop visits again down the rad. As you can see when I get into things, full throttle is the name of her . My vision issue is the big hold back . Doc says Iím not to set foot in the shop or be around rotating machinery. Absolutely no welding. Well being told I canít do some thing goes against the grain  I will listen to the argument . But it better be pretty convincing or it will bounce off my hard pointed head. LOL

Ok so Iíll dig up a picture from chilerton steam and post it . My birthday s comin up so this is my personal gift. Iíve worked for nearly 70 years so itís my break .

Glad to be here and Iím looking forward to more conversation

Here is chilertermodelsteam.uk.

Site. If you go there look under models and see the quad mill model there is a video of it running.

There are a number of others to as well as a new boiler. I think they may have an electric on in development. Their boiler certainly seem pretty tough compared to the USA

Welcome.

I think you mean here


     Nice to see their website, I was familiar with some of their engines but had no idea that they made so many!

Iím sorry for all the spelling errors. I was on my iPhone which is even harder to see. I didnít do a good job proof redness. I got interrupted by Amazon. I got more steam stuff. 

Anyway Iím progressing on yhe massive boiler build. A simple project has become very big and much more complicated than planned.  Now itís threads.  I had planned on using all not  US THREADS BUT MANY  gage snd extras are ME threads. So what say yes. Should I stay with /8Ē NPT and add occasional 1/4Ē NPT OR SHOULD I JUST GO WITH ME threads. Turns out there are. Bunch of these too.then finding adaptors or making them is an iddue.  can I just tap drill ME say /4 x 40ME tap drill size and either tap it or drill it out to 1/8Ē. NPT and tap it.  ?  Can I drill out a 1/8Ē NPT  pipe plug to 1/4 x40 ME thread or do I have to come up with captors I am going to make a tap slighter so they will be straight.    How about thread sealers can I just use Teflon tape or do I need to get pipe dope. ?  Iíd like to use small diameter gages if possible to keep the clutter down.
 I can get AN fittings in aluminum or stainless steel. Iíd like to use a braided Teflon supply line. AN 3 I losing favor as brake line but is readily available . it takes a social tool to expand the tube and open up the braid but I can live with that. Iíd prefer not to use direct hard lines but I can. My son uss stainless steel tube so it would look nice  but it is difficult to handl and leads to unwanted bend that are hard to straighten. It possible to use a crimped hoe too. There is a big hydraulic store not too far away. Iím pretty sure his hose is high temp rated.I can get red blue or black AN fittings or stainless.  Stainless is not cheap but more durable.

Iím looking for ME taps and dies. So far sets that are offered have a lot of what Iíll most likely never use . It looks like 1/4 4 TPI ME is about the size I need. It seems like pretty common on things Iím im interested n, however when it comes to descriptions things get shaken, Iíve already got a pile of taps as dies Iíll probably never use .  Iíd Ike to use small gages to keep the clutter down. I thought I could just use /8 npt across the board and drill and tap theses plugs as needed but my machinery manual is out at the shop so I have to ask is it possible to drill and tap 1/8 and 1/4  ď in NPT FOR THE 1/4  x 40 metric or do I need to go with 1/4Ē Npt .  Can get an 3 and An 4 easily both in braided Teflon or standard race car braided gel line the fuel line will hold up to anticipated steam temps and pressures with out problems plus itís very flexible so I wonít need big loops of it. I can get a variety of fittings bottoms rainless and aluminum I think the hydraulics shop has SAE brassctonthatveillbwork with either material or size  so whatís the opinion. Iíd really like to kee things neat and clean looking . I could do hard lines too but invariably a line gets bent a little then gets a double bend and looks messy

One more thing I have acsitevthatbhadcaboutvevryboptionicouldcwantbbutvincantvfindvitvevennyhoughbibsavedbit. Iíve looked at Stewart and model steam but Iíd like to keep it on one or two suppliers .

Yeah ghastly the one Iím ordering.just a couple options. Throttle and reverse valve and  couple port extensions, maybe an oiler I may order a container of oil just so I have it to start with. I did find a quart of steam oil. Supposed to be ither Valvata  or at least itís equivalent. I think it was $20 or so but it will last a long.  time.  I got pay al all set up so it shod e asamless order I hope. They have been really good to deal with on support. I ge return email the next day soexcelentin my book.

Iím having order issues. Iíve been awake over 24?hours. Their server seemed to stop responding about midnight here. Finally about 3am it let me in so I could complete the order but I still could not complete it. I emailed them about the issues and they got back to me early today, so a big plus I think. Still could not get through so I called my bank and Iíll do a wire transfer. Iíve done this before just not directly on line it only requires order total, routing number snd account number you want to send money to. The important thing is not to make any mistakes as the transaction is not reversible I sold my street rod for about 50 k this way and it was nearly instantaneously transferred  it is not the way I wanted as it costs extra to do this but in this case itís the bet way I think.

I finally got everything ordered.  Then gentleman was vey patient with me answered all my questions I finally had to call directly. I called my phone co and set up international calling. Turns out to be a pretty good thing and not as expensive as I thought. It is a monthly charge but itís easy to stop or cancel without extras. May end it if I donít use it. There is no start or end charge. So itís something to look into if you are dealing overseas it makes card operations easy and safe as the bank notifies almost immediately. I just called the number given and the transaction went seamless actually easier than site orders.

All I need now are the 1/4 40 ME taps and dies. I havenít been very successful on Amazon.  I donít need another 50 piece set that Iíll use ably a couple items from.  I can fore see making special adaptors so not a big deal. It will be a couple weeks before I get this unit but Iíll post some pictures I donít have a YouTube site yet. Thatís an addition if I decide to do that  for now Iíll just make short camera videos.  Itís well below 0 F today with a brisk wind. Not fun to be outside.

Ok so now I. Get to shoe hoe green I really am. Ere I doing college again Iíd SLOís do electrical engineering along with mechanical engineering.I had lots. Of mschine shop experience so I was way ahead of the gam in automation and the aero space stuff. Th internet was just starting then so ghereere many trips to yhe library. Now it just a mttrr of looking things up with this keyboard. However.

Iím severely lacking in electrical knowledge.

An easy question I suppose. But if I drive a small stepper motor with my new steamer or another power source hat is the output, if any. Sc or dc.  I have learned so far hoe to convert he stepper to a generator  and I have the rectifiers condensers and even a breadboard with a box of electrical jumper resistors even a resistor hart and a bag full of condensers. I have. Some hook up wire. A digital ulti meter box of leads a brand new soldering iron that I do know how to use even a small butan torch for brink wrap. I usd t do trailer building and repair so lights ere a steady problem that I fixed.

Now how do I measure the output of the dynamo I have andwhat Er the steppers put out or even take to drive. I saw a video where a guy ran a generator with his steanner  calculating th output and ultimately to hp. As small as it was.  I have a source for an electric clutch/brake. So it would not be hard to make a small digital scale set up to measure torqu directly. But he did iteletrically by calculation. He seemed to just lad hhisenerator reading volts an watts or MPs gradually ing more tam until his engin almost stopped.  Anyway I need some technology help.   I can do an gearing Iíll nrpeed there is a neat gearbox option for this turbine too.   Itís neat an good looking.

 So Iíll reellyappreciate any help.

Thanks byron

Hi Byron! For ME tapp/die I recommend the fine product from PM research here in the states. Here is a link to their tap/die page
https://www.pmmodelengines.com/product-category/tools/
They offer tapered, straight, and their own breed "UST" which is something in-between and is supposedly compatible with both tapered and straight. So far the tools seem well made and cut very well. I just bought a set of the 1/4-40 UST tap/die and they work wonderfully with all the fittings I have. PM research also sells all sizes of little fittings that you can imagine and are of very nice quality. Can make your build quite a bit simpler if you can pick exactly what you need. It is important to note and you probably know already that NPT threads are a lot larger than their name. A 1/4-40 ME is very small in comparison to a 1/8-npt. Might be preaching to the choir, but I figured I would mention! Sounds like you are making a lot of progress towards what you want!

Continuing my electric boiler build.Iím searching for technology as Iím new to much of this. My electric boiler will have two immersion heaters one 750 watt one 1200 watt. I plan on two separate plug in at my home so I donít overload circuitry Iím looking for a timer so I donít accidentally lave it on also looking for an automatic level controller. This thing is getting more complicated every day. Now lunch conversation turned to materials for fittings. Brass or bronze since Iíll be making some special ones I have a choice the boiler is 4Ē 3/16Ē wall aluminum tube with 1/2Ē end caps. Teflon o rings Iíve added a through rod with bolts tapped and sealed for extra strength. Opening or ports will be tapped into the tube so no welding 1/8 and 2/16 npt tapped holes I also have ports provided for magnesium anodes I have magnesium round stock so I can make custom sizes if necessary so whatís preferred? Bronze or brass fittings I can get either I think. Some gages come with brass that I can only use as is but I can purchase most of what I need in either material. I can get brass hex but bronze only comes in round I can still make  what is needed the hex block with 5 c collet works every time so I need som each here.I wish I had drawing but I really add a mess by spilling water all over my working sketches. Iím trying to re make them now.

Thatís the machine itís due Friday

So quick question Iíll need some oilers so far I have not found and ready made one with  2/4 40ME threads so I can make them ssvinhavevtap and die coming
Now what is he usual thread in grease cups or oil cups? I have not seen this noted anywhere if I can find it Iíll just make the threaded end 1/4 40 ME THEN  use the tap as threading tool and thread the new cap the same I can use it bothbinternal and external threads. I think the lathe will thread 56 TPI  with maximum gear change  other wise Iíll just use the closest I have. Havenít done that small thread in a long time but itís easy material to cut  I donít want to make steel ones but I have some leaded steel that cuts like brass.  We might even have some gun bluing left in the back room .

I just got my new steamer. I canít believe all the parts fit into such a small box. There is no way Iíll ever ge term stffed back inn. I have to paint the frames. Itís actually two engines coupled together. Very interesting. The mount screws are tiny. I thought a 2-56 was smal. Thatís about what this engine takes but metric. So Iím going to have to get metric I guess.  . My boiler build is progressing. I already added an nichrome to the length. Iím making the insulation wrap now. Itís alsa wood formed around the cylinder. I also now have two 1100 watt heaters.  M told itís not enough. I have room for more. I just canal oope flame in my home. Yes I have gas heat and hot water but they are self contained, out of sight, out of min for now. No Iím not going to tap into enthroned.LOL just masking off surfaces that must not be painted is a ig undertaking as they are very small. . Iíll potmoras thins progress.
