Dan,

This is looking great! I love the early Shays and will definitely be following your build.  Question for you. Any idea why I can't see the images in posts 6-14?  All others show just fine.

I poured some steam jambs today. I will give them a go in the lathe tomorrow.

Quite nice Dan!

Thanks for going through the effort. That casting rig looks like it could be pretty handy from time to time.

Yes a casting rig is handy for multiple parts but it is an on going learning curve. I started to use the electric crucible on the last few casting sessions and I like it a lot, way less noise than the torch at full throttle.

Here is the steam jamb in the lathe set up for a 7/32 reamer. I made the ends long enough so one could be used for chucking and the other one for the steady rest.



I made the cylinder ends and I already had castings for the gland. The steel part in the center is a drill guide to tap the cylinder for 1.2mm studs. That will be first thing tomorrow morrining.

Here is the setup for drilling the holes for the 1.2mm studs. Having a dial and an accurate depth stop makes this a fairly simple job. Only 8 studs Jo :NotWorthy:



Switching to the tap stand I used one of the covers and a spacer to bolt the cylinder to the vise.



Here is the finished steam brake cylinder. The fixture for drilling and tapping and the mandril I used to face the cylinder ends are the other bits in the photo.



Will it be a working steam brake cylinder?? 

I left that as a future option as a working locomotive is first.

Only 8 studs Jo   8)

 :o That looks a very small vise to be using to hold such a long casting. Were you not worried it might move and break the drill? :paranoia:

Nice looking little drilling machine 8)

Jo,
Yes I was a bit worried, but the casting is bolted to a plate which is clamped in the vise. I did not have enough head room for a larger vise. I just peck drilled the holes as the guide was fairly tall for such a small drill.

Yes I really like that drill press most of my work is small to tiny which is a perfect fit.

I have finished riveting all the parts on both Shay frames so that milestone is worth a progress photo.



The next section will be the trucks, I will be using Stock Drive bevel gears for this build. I am not ready to cut proper scale gears yet.

When I get to the engine it is a two cylinder marine style vertical so I will cover that section here with all the machine steps.

If anyone is interested in more detail on this project it can be found here:

If you have Shay questions you can ask there or at the LivesteamShays yahoo group which could use some excitement.

Looks like you have been busy on those frames Dan...or did you make your little assistant do all that riveting for you :)

Bill, thanks that little assistant keeps wanting better tools...I already made him a bunch of tongs and several hammers but I think he is just collecting tools.

Dave yes those are the brake cylinders. I think they will be dummy cylinders for now but I can make a working unit with the castings.

I have to add the running boards and deck boards. A nice wood working job.

All the deck boards, running boards and foot boards are in place. It took 76 screws and nuts all 1.2mm for each loco.

I was not really prepared for just how plain this would look. It looks like a barn floor.


Here is the bottom side.


I liked the saw marks so I left them on the bottom side.

Cheers Dan
