Thanks George!
I'll have to be careful of that, because I do have to do some additional work on that piece.
Is there any way to harden brass?  Short of work hardening it by bending?  I could unbend and re-bend, but I'm afraid I'd end up where I was before and the brass wouldn't bend to shape and just spring back...

Thanks,
Kim
Work hardening, either bending or hammering/rolling is the only way, brass and copper does not harden with heat treating. Does not take much bending, just flexing it can do the trick.

Hydro testing... a pain in the   :censored: but ya gotta do it.  Looks like your test is a success, smooth sailing now. :ThumbsUp:

Try hydro testing 9.5 kilometers of subsea pipeline that goes up & down hill!........first attempt didnít work, why not well you canít get the gas out of the hi point! After 4 days trying we finally managed to get a soft pig into the pipework offshore........this is on an unmanned platform so daylight only allowed. By the time I get to work to night hopefully the pig should have done its job & pushed the gas out.....

Hi Kim,
 Still following look great!

Cheers Kerrin
Get excited and make something!

Very nice work with the boiler, casing and pump, you get out of all the traps easily; a very interesting thread all around...
I didn't see any layer of insulating material inside the casing, do you have room for a 2 to 3 mm layer of ceramic fibre, as we put on small gauge locos ?

Hope you get it working quickly Kerrin!  Sounds like a royal pain!

Thanks Zephyrin!
Interesting thought on insulation.  Rudy doesn't seem to us any, and there isn't any room on the top, maybe some around the sides.  But I'm not sure it will see enough running to be worth any insulation.  But I guess you could say that about the rest of it  :naughty:  But I won't!  :Jester:

I'm having a grand time and I think it will work!

Thanks for the comments guys!

Well, not a lot of progress on the steam tractor today.  I had several things around the house that Iíd been putting off.  One of which was to rebuild our gate.  Its been in bad shape for several years, but this winter some of the boards rotted completely through and were falling off.  Clearly time to do something about it.  So this was my solution:



Like I said, not much on the tractor, but a good bit of work for the day regardless.  And it looks pretty good if I do say so myself!

Thanks Bill! :)


Got some shop time time today, so made a little more progress on the Steam Dome.

I needed to cut an arc into the bottom of the Steam Dome tube that Iíd riveted up last time.  So, I used the same dowel that I used for drilling the rivet holes to help the tube keep its form, and clamped it in the vise.  Then used the boring head set to the appropriate diameter and carved a nice arc in the base.  Like so:


It lined up nicely with the saddle, and I made a little jig to hold it together and set it up for silver soldering:


Hereís the after soldering shot.  It worked out pretty well.  I could have used a bit less solder (got a couple of blobs) but it turned out pretty nice.  I used the #000 tip on my OA torch, and maybe I should have used a bigger one Ė there was a lot of metal here (and my jig added some heat sink too.  But I got it done.


And after some clean up, hereís what it looks like:


Then I had to take a quick peak of it sitting on the top of the boiler, where it will be mounted soon.


Thanks for stopping by!

Nice job on putting the arc in the dome! I would have been afraid of the cutter deforming the far side as it came out, but it looks like there was no problem. Clever!

Thanks Chris,
The plan (hope?) was that the wood form inside the tube was a good enough fit to keep things from deforming too much.  I didn't take too deep of cuts, which may have helped.

The wood no doubt kept the cuts less interrupted than they would have been...clever idea there. The final fit looks really nice too Kim.

Oregon is a nice state. (All states are.)

I may come visit Oregon.

I know a fella that would put me up.
He probably wouldn't even mind if I stayed a good while.

Hopefully he won't want cookies in return. I can't seem to get them out of you know who.
