Guys, I'm building the "new" shay and was wondering whay you guys are using as far as bolts and nuts go. Kozo uses metric, so are the most of you useing that and are able to find the hardware or do you convert to inch? Also not being a pro or machinest by trade, how do you guys get such a nice finish. I know brass is better to get a nice look finish, but stell is real hard. I have been using 1018 cold rolled and do not always get good results. Should I rather use hot rolled A36 or what is better to use besides brass as I am trying to build it in my small buget :-) I have pics here: ironhorse191.webng.com/Click on the shay#14 pic (my inspiration) and then you will see the 4 end brackets I have made so far. I need to update those as I have completed them last night. I will post new ones tomorrow to show you all. I'm also thinking that my speed is wrong...  I'm also building a "G" Scale De Winton. Thanks, Daniel |

Ironhorse,
Can't help on your questions  (I'm building the A3 in 3/4"), but I sure like your web site!!

If you have trouble finding metric you could convert. divide the diameters in millimeters by 24.5 and you get decimal inches. See what sizes come closest to that in imperial. I have an excel spreadsheet with some conversion information on it. I don't have a name that I can find to give credit to for it. If you PM me I can email it. You can also join the Yahoo group groups.yahoo.com/group/Builders_of_Kozos_Engines/ in which case the file is available there in the files section. Cold rolled tears when cutting. Hard to do nice cuts on it. That's why Kozo recommends leaded steel. I don't know alloy names/numbers or I would give you more help but if you can find a distributor (McMaster Carr is just one) you can ask for a free machining steel alloy. Or leave enough to do a lot of filing and sanding/polishing. Paul |

Thanks Paul I got the doc from the group. I have many ones too but did not have the BA ones. That does help.. ;D
Thanks,

I will also look for better steel too to use.

The guy that typed up that list responded on the other group and said he got it out of the Shay book (I forget if old or new, new I think). Glad I could help a little. I have so little to offer in the machining area.

The leaded stock that Paul mentions can be found listed as 11L17 or 12L14 stock The "L" meaning it's leaded. The lead makes it machine more smoothly but it's not recommended for applications where you're going to weld the piece. That stock really threads nice so if you're part calls for mild steel, try it. I also agree that cold rolled stock does give as nice of a finish as hot rolled A-36. Even when you surface gring it, it can show small pits due to the cold rolling process.

If you'd like to see my shop, go to www.ossenbeckmachine.com and check out the gallery. Of course this is a company, not a private hobble shop so don't think I'm trying to show up anyone. I just happen to be fortunate to have this shop at my disposal. My business partner thinks my train hobby is a waste of time. His mom probably didn't give him a train set when he was little. |

I just checked McMaster-Carr's catalog, if you needed, for example, a 1" square bar by 12" long piece of mild steel, 1018 cold rolled is $9.61 while 12L14 is $13.44 for the same size piece. Just to compare.

I think plastic stuff would be very useful for you. Because it would definitely also fit in your budget. Good luck for your this project.. plastic caps & plugs | tube end caps |
