The Home Machinist!

30' for Caribou (0-8-0) as dad says- and my Britannia is the same. https://live.staticflickr.com/693/32734632045_37eaea737f.jpg HB Britannia 1984 by Peach James , on Flickr That's the Brit on the 30' curves that dad has- we had the Hoffman Hudson that there are photos of on the same track (well, at ...

Legal to 1 000 000 PSI in BC if the boiler is <22 sq ft :) (Boilers under 2m^2 in bc are exempt from the code, regardless of pressure) (now, common sense is a different matter...) I'm running at 165 PSI on the traction engine. No adjustment to the reset on the safety valve- other than tapping the sa...

I would go for an AC Alternator, probably permanant magnet, and then float that to DC across a bridge rectifier, and then an electronic voltage regulator (buck-buck) to regulate the power to ~14.7V to charge the battery with. The size of the electronic components will be determined by the size of th...

Bones, the easiest way I have found to put photos in here is to use Flickr to store the images, rather than onsite. This is an old forum...with its own series of foolishness. (that's not to say it's bad, it's wonderful that we have a forum like this)

I also have a set- I will take a look when I get home tonight.

Be aware, it is a right @#$@#$@# to get to run, with a number of small drilled passages that have to come out right for it to work...

22 sq ft in BC (2m2, legally). Ontario has some weird HP/surface area calculation, in addition to the 10 ft limit. the big traction ran afoul of it- even though the boiler was built in MCCR days (before TSSA was a thing, and the hobby side rules were a bit different). Basically, my understanding was...

I would think (har) that the best would be to get it all together oversize, then heat treat it (normalize) it, then finish machine it.

Thoughts from the rest ?

Glenn Grasley and I have built four 2.5" scale K-27 boilers. The Ulin drawing is pretty much useless. I have copies of the D&RGW drawings and scaled the boilers from those drawings. Hey there! Well, I Managed to find the drawings…. And yes the boiler drawing is what I would also consider u...

Assuming we're allowing the 80's to be considered "old"... https://live.staticflickr.com/7534/16346439982_89968536dc_k.jpg Rex Smith Atlantic 1 Older than the 80's, this is Rex Smith's Atlantic, which I understand lived in Port Rowan, Ontario. (on Lake Erie). It probably ran at Sun Parlour...

My yard is much the same way and has me thinking of building a steam tractor as well. I would love a 1/3 or 1/2 size Case but seems like castings and plans are few and far between. I believe there are 3", 4" and 6" Case casting sets out there. The other "big" forum for stea...

Oh, and on Torque- oh, we have it in copious quantities. Not so much HP, but torque... I've done wheelies with the 4", in that it will quite happily rotate around the rear axle even if my slightly lardy bum is NOT sitting on the tender :). (so something like 800 ft lb of torque on the rear axle...

If my dad sees this, he might comment on the 2" roller. I know it has a completely home made gear. Done with drilled bottoms and file. I believe the gears on the 4" Fowler are cast, then machined. "real" fowlers were just cast...not machined. In relation to current applications, ...
