Started a new twin cylinder engine.

[steamer]

Sorry to hear about the smoke Tel. Recently did the same to my big mill....It was the capacitors ( 220V single phase 1 1/2 HP)

So which neighbor has the nicest washing machine? ;D :big:

Good luck....

Very interesting engine, Tel.

I think it was Brunel Models (or possibly GLR) who made a kit of the very same engine. Having a quick look through the various web catalogues of UK model engineering suppliers, the correct supplier escapes me at the moment.

I'm finding this build very interesting. This is not your run-of-the-mill (sorry ) engine.

Cheers,
Phil

Thanks blokes. With the lathe back in action now I might be able to go forward a bit, although that's been complicated by my also starting on the Ridley Half Beam currently running in AME.

Yep Dave, Brunell do a very similar one, except that it has trunk guides and the 'A' frame is solid right through instead of side plates as per the J. Wood of Ramsbottom version.

No, I haven't abandoned it, in case you were wondering! Got a little bit more do the last couple of days - this thing is starting to look like an engine!

Ah, I thunk so!

Which is about 5 miles away from me !

Looking good so far

Tel,

Yep, it sure is starting to look like an engine and a very nice one two. :

Best Regards
Bob

 

[SignalFailure]

Any updates Tel? ;D

 

[tel]

No mate, I've been a bit slack with this one - been working on the Ridley Half Beam and did the dividing head, and working on a QCTP to Harold Hall's design. I do have the slipper guides made, got to do the pistons and rods next, before they can go on. Soon(ish), I promise!

 

[tel]

Yow, how long since I did any work on this - too long.

Ah well - a little bit more progress has been made, the piston rod, piston etc all fitted to the l/h side and the slipper guides fitted.

 

[CrewCab]

Another thread I missed earlier : anyway, up to speed now Tel :bow: ............... as ever, nice work mate 8)

[Maryak]

tel,

Wondered what happened to this engine, I love the beamer. :bow:

Best Regards
Bob

 

[tel]

Inched a little further forward today - the second (r/h) piston and rod fitted, but not the slipper guides yet.



Instead I had a play around with the 'rear' exit exhaust system - I think it's gonna work

 

[zeeprogrammer]

Looks neat! I can't wait to see it run.

 

[tel]

OK poison curls, today I got some more done on the exhaust manifold. It needs a 90° flanged branch, 1/2" long, so I thought I'd go into a bit of detail with it, in case someone ever needs to do something similar.

First, a bit of 1/2" brass is centred and spotted near the end


Then drilled thru 1/4"



Now we move to the lathe, and take a skim to establish the length of the 'pipe' section, which in this case is 7/16" from the inner edge of the hole



Next we centre drill the end, and pop a drill thru so it spots the other side of the hole - makes things a bit easier after.



Then turn down the 'pipe' section to 1/4" diameter - which, of course, means the outer end of the bar goes away somewhere



Now it is an easy matter to drill out the piece to the required 5/64" diameter and part off



Reverse the piece in the chuck and face off to thickness and the piece is made



A dry trial fit. Hopefully tomorrow we'll get the flanges drilled and tapped, and the branch silver soldered into place.



Watch this space!

 

[ozzie46]

Now THAT is neat! Thm: Thm:

[zeeprogrammer]

Very nice. Thanks for the pics tel. Very helpful.

 

[tel]

Moving right along .....

Forgot to take any pics of drilling the flanges, so you'll have to imagine that bit. When I came to look for it, I couldn't find my handy dandy fitting soldering jig, so I made another one. Thes one is a bit tidier anyway



The bits loaded into the jig



And flux/heat/solder applied in the usual way



A trial fit



Almost forgot to drill thru into the main pipe - that would have been embarrassing



Where we're at today

 

[tel]

And just to give you a sense of scale, here is one of the flange bolts

 

[Krown Kustoms]

Very nice, I cant wait to see this one run.
-B-
the pipes and fittings are a great touch.
how was the 90 done on the pipe?
