Re: 2.5" Scale 36 Ton Class B Shay
I'd make a big boring bar out of some hardened drill rod to avoid the flex from the long stick out. My understanding is that there isn't a big difference in rigidity for different types of steel. Solid carbide bars are more rigid, as are steel bars that are a larger diameter. Another option is to m...

Crosshead Guides
Got the crosshead guides all machined up a few days ago, and they turned out great! I'd say they're on par with the crankcase casting in time to setup and machine. At some point I need to cut the reliefs for the connecting rods, and the mounting spots for the mounting bracket to the frame. Some day,...

Crosshead Guides
Started working on the Shay again, and to start I farmed out the reverse links and die blocks to a friend in the hobby who will wire EDM them and get them machined up nicely for me. On the home front I started on the crosshead guides, and below are some pictures of the facing operation to get them t...

Re: Clishay Transmission Questions
I see one of my old videos got shared! My only recommendation would be to offset the holes for the idler gear shafts a few thousandths so you can adjust the gear lash, and make all the shafts out of something harder than the cold rolled steel the book calls out. If speed ever becomes a problem for y...

Re: 2.5" Scale 36 Ton Class B Shay
Haven't made any progress building the Shay in the last year. I got busy doing some other projects for other people with a boiler for my grandpa's Ken Schroeder Shay being one of them, and getting my 2-10-2T running. I had some downtime at the end of the year after a procedure that gave me the time ...

Re: Alternative Fuels
I ran my CliShay on wood pellets a few times with a special grate that I had made for it out of perforated plate steel with risers to allow more secondary air through. It made plenty of steam, but the smoke and sparks were more than I could handle even with the baffled spark arrestor I'd sometimes u...

2.5" Scale 36 Ton Class B Shay
I'll start this off with a link to my other build that this project evolved from: http://www.chaski.org/homemachinist/viewtopic.php?f=45&t=106921 I've made so many changes to the design that I think it deserves its own build log. This all started late last year when I got the bug to start workin...

Re: Building My 2.5" 20 Ton Shay
Very nice! I left off with my Shay having finished the gearside journal boxes, and the brake cylinder.

Re: Another CliShay Build
Better late than never to finish it! I finished mine about 3 years ago, and added a duplex pump to it last year. Really reliable runner after I worked out the bugs that it had after building it. I would recommend that you key everything that slips together(wheels excluded). I didn't and have had to ...

Re: Building My 2.5" 20 Ton Shay
I got the brake cylinder mostly finished off, but now I’m kind of lost on how to set up the rods. Should the rods be set so that when up against the stops the brakes are fully applied, or the other way so that when up against the other side they are fully released? The way the guides are made it’s o...

Re: Building My 2.5" 20 Ton Shay
Life has a way of changing things I guess. I started my first full time job(I'm thinking career now) back in January, and my grand plans for the Shay have kind of been tamed down. I've decided that since I don't have much time to work on it anymore that I'll just continue down the path that I had or...

Brian, are some of those staybolts hollow?
