So far so good
-
Looking good. But do you have clearer pictures?
-
Hope this is a bit better ,made from stock material using mini lathe.
-
A very nice job there MCR. Lovely bit of machining. Justv shows what you can do with a bit of thought and a small lathe.
-
I have never made much more than a pulley wheel before but with help from a club mate I have dramatically increased my engineering understanding and a tutorial each week has allowed me to make steady if at times painful progress.
-
That is fantastic! well done, I'm really envious. :o
I would love a Borderer, but I'm so far from being able to make one.
-
I would not be so sure.
I have approached each part as a project in its own right the result is that I can now see the light at the end of the tunnel.
Started the project about May last year.
-
Very well done MCR, a real credit to your abilities.
You are also doing it the correct way, concentrating on making one good part at a time, that way you don't get overwhelmed by the complexity of the whole.
:-))

Well done MCR you have done something I planned to do 40 years ago but have still not started!

great,,wery nice it is,,........,,,,,,,,,,make a video on your tube when it ready to run,,,,,,,,,,,,,

This shows it much better. I like the classic marine engine look.
Is it just the tricky perspective that makes it look like a compound engine or does it really have different sized cylinders?
What plan did you use?
-
What plan did you use?
I assume that MCR got the plans directly or indirectly from AJ Reeves Engineering.
https://vault1.secured-url.com/reeves2000/shop_item.asp?sub_cat_id=163
The engine was originally described in Model Engineer a good few years ago and is a design by John Bertinat. Reeves carry plans and a set of castings for the engine and water pump, though as MCR has shown, it can be built from stock very well. A bit later Bertinat described (again in ME) a smaller version off the engine called Marcher There's a link between the names, the Marches is the name given to the Border area between England and Wales.
I have a Marcher part finished but have b********d the main cylinder block. The steam passages and porting on the smaller engine are tiny and defeated my abilities a couple of years ago. I ran a 1/16th drill through the side of the block while drilling a steam way. Given the cost of a replacement casting, I might well try machining one up from a block of gunmetal now that I've just got my ME workshop set up again.
Cheers

Hi,
cant you solder a piece of bar in the hole or tap it and fit a screw and file the screwhead flush

Sadly no. I've done that before when i've made a mistake but on this occasion I made a real mess. I needed to drill 2 x 1/16th angled steam passages from the cylinder tops down to the inlet ports. I managed to drill through the port and out of the steam chest face. Not recoverable I'm afraid.
Basic lesson in checking the set up and then checking it several times more before starting the drill :((

Looking for a project on which to learn basic engineering my mentor suggested the borderer using the article mentioned earlier.
He has finished his engine which he built one step ahead of me instructing as he went along. He has run it on compressed air at the club everybody was very impressed.
Its not a compound ,twin cylinder double slide valve.
-
This should give some idea of scale
-
Hi MCR,
Very nice engine indeed, I knew action mans eagle eyes and gripping hands would come in usefull some time {-)
What boiler are you using to provide steam to this engine?
Cheers
Ian
-
This is a boiler I purchased on Ebay at a rather good price (better than the cost of the raw material,have you seen the price of copper?).
Its a triple pass scotch marine boiler I believe.
-
that's a beast of a boiler, you're going to have one gem of a steam plant when all done. looking forward to following the build.
-
Almost finished pleased with the progress I am starting to forget all the head scratching bad temper and the overflowing swear box!
-
Oh joy of joys she lives she lives. After a couple of frustrating days setting up the timing I could not resist and had to try air through the engine.
Without any seals and with air coming out all over the place (only had two screws in the cylinder covers I did say I could not wait) I linked it up to the compresser.Would it or wouldn't it ? With air blowing everywhere it twitched then sprang into life.Throwing the linkage over the engine stopped then changed direction.
I don't think I have ever smiled so much.
Now on to the boat!
-
CONGRATULATIONS! :-))
the feeling must be amazing, llike giving life to something.
-
If you look at the thread on copper nails you will see Wide a Wake a model owned by Guy. I have made a start ,the keel is complete and the hull shadows and jig constructed. By the way did I tell everybody it RUNS IT RUNS.
-
Hope this works:

If this does not work I will have a re think

-
It works! Lovely job, you have every right to be proud. :-))
-
Very nice. Now what are you going to power with the engine?
-
I plan t build the Wide A wake which is an open launch with clinker planking.
-
Just added this:

-
Considering you couldn't open the file initially Mike, it must haave only taken a couple of hours from drawing to ON.
Regards Ian.
-
The drawing was what I had been waiting for Ian so once again thanks.

I have just pulled the hull from the mould and added the first coat of yacht varnish. I discovered a good site on lapstrake building (clinker ) it has been an interesting process to date.

Can you post a link to the "site on lapstrake building (clinker ) ", please.

hi.........Mcr you launch look great...........have you eny more photos of it
Regards Bernhard
-
Don't know if you went to Harrowgate Mike but there was a display by Bertinat's son of the whole collection of his dads engines including both versions of the Borderer and Marcher. Slide and piston valve types. O0
Regards Ian.
-
This is the one :
Fab work and it only represents 2/3rds of the collection a true inspiration.
-
Made a little more progress most in mock up as I try moving stuff about.
The boiler is upside down as it sits in the hull a little better at the moment.
-
woow ,,,,what a boat..........you have don,,,,,,look so fine............................
Regards Bernhard
-
Wow, just beautiful. If you change your mind about this launch i've got first dibs on that boiler :-)). A true inspiration mate.
Greg
-
Your hull turned out very beautiful!
-
After a little more effort I have completed the stern.
-
hi,,,,,,,Eny news with the launch,,,,eny more photos
Regards Bernhard
-
Thanks for the interest:
While I have been on holiday in the USA for the last three weeks this is the current progress,decks complete yellow wood rear deck which was Pear has been replaced as I didn't notice that I had mixed up the timber my son pointed this out after I had varnished the decks >>:-(
The foredeck is removable to give access to gas supply and the bulk head is still only a mock up,the flooring will hold the engine boiler etc. and is also removable.
-
Many Thanks..................what a great boat it is.......first class work you have don there
cant get enof photo of it,,,,,
Regards Bernhard
-
Turns out the boiler purchased from Ebay was soft soldered and sprayed with undercoat to hide the fact <*<
So time to get the saw out to salvage some of the copper.
Once again with lots of help and support from Mick my mentor this is the result.
-
Boiler construction
-
Nice work. What diameter does the boiler have?
-
Five inches if you check the previous posts you can see that the original boiler was substantial.
-
Nice boilerwork there mate- good to see someone making their own- and great you checked the joints first too!!! Idiots >>:-(
Greg
-
I have learnt a valuable lesson, don't buy boilers over Ebay.
Boiler has now been tested to twice its working pressure all went well so at least I have peace of mind.
I even think that the vertical boiler looks better than the original horizontal.
I tried to be philosophical about the whole thing at least no one was hurt, this might well have happened if an unsuspecting buyer had fired the boiler up >>:-(
-
Yes your right- really does suit being a vertical design, and looks scale too now.
Keep up the great work.
Who's your mentor by the way...?
Greg
-
A fellow club mate who joined about 3 years ago.
He comes from an engineering background and offered to support me in building a steam engine by giving advice and help as he constructed his the same time.
A rather steep learning curve I can't describe the feeling when it first ran on air.
-
A little more progress
