Hi PD's....&  Eddy....could I please withdraw my vote?...publically so it appears as it appears ....... ....Derek

[Eddy Matthews]

You can now "Remove your vote" Derek, though I'm confused as to why you want to do that?

Hi PD's & thanks Eddy for the 'reversal' of vote facility....its like a cool off period ....after you sign a new Contract 

Reading between the lines.... ...by comments, I saw members [prospective purchasers] thinking that the MVh TC 14X18 engine as built could be used in a conventional model vessel as is

It is a beautiful twin cylinder engine......it would be self starting with no dead spots....but it does not have any 'reversing' gear....

I acknowledge that John [our bogstandard] suggested that he may be able to incorporate the reversing steam input from the EMOJ project

"Because of it being a piston valve, wack a fwds/rev controller on it and you are in business".......

However this is not defined .........regards  Derek

Just to answer a few of Derek's questions.

The one nearest the bench is a Japanese Acer, behind it is a Smoke Bush, olive green leaves in the summer, then change to a nice red in the autumn, on the wall is early flowering Clematis.

We have all been wearing wet clothes for the summer, they soon dry out, and don't need ironing. Getting a bit chilly now though. We are hard as nails in the UK, not like you wimps from down under.

It will have a reversing and speed control, dead easy on a piston valve or oscillator design.

And for Steven,

The one on the plans isn't a round style slide valve, it is in fact a piston valve, and as mentioned above is easy to reverse and control, a slide valve is a different type of beast, and as you said, to reverse one that hasn't got a reversing linkage can be a bit of a pain. Usually a gearbox or a slip eccentric is used.

Just a quickie,

On my last statement, it sounded like I have been doing these engines for years, not so. It was our long lost friend Sandy who introduced me to these types of engines and I would like to thank him (if he is looking) for making me aware of all the different types, so I am not a super expert by any means, but I did make sure I learned enough about them on the way to making a few.

Another item is an apology to Malcolm. I went to the show today but unfortunately didn't stay very long (I was on my way home by 12:30), and even by looking as much as I could, it was so crowded (I even lost my helper who was with me), I never managed to find you, maybe another time, when space and time allows.

BTW, what I saw of it, it was a real good show, but a bit tight on space. So if you are inclined, it is well worth a visit. Still a few days left.

  PD's........I cannot believe that bogstandard would leave Vinne behind @ the Exhibition then said  ............
(I even lost my helper who was with me)  ....do you think John, ......that my parcel of KANGA bones will intice him back?..........................Derek 

[bogstandard]

Sorry I didn't get back to you on this one Derek, I have been busy with my new plaything.
I don't think my mate Ralph the helper (6ft 4in superbeing) would like the kangabones, he is a vegetarian (no, not a cabbage). Vinnie has now shown up again, a few more scars, but a big grin on his face. Maybe he got his wicked way after all.

So, the vote will be closing soon, so make sure your wishes are known.

mmmmmmmmmmmmmmmmmmmmmm PD's...... my original vote has been reinstated  ........

One of the good features with our PD Forum ....is that it is based the Westminster System  &  &  ...so who would I as of  humble convict stock as to [TOO]  question the next [superlative] engine build  by our  bogstandard..
Derek 

[bogstandard]

It looks like we are going with the planned version.

So, as soon as I am able, I will start the post.

Don't hold your breath too long, I have a lot to do before I can start, maybe in a month or two.

John

[derekwarner_decoy]

OK...PD's.....it appears that we have 3 members + me ...so equals 4 members desires of the 'bogstandard horizontal twin'

My role in real life is a facilitator so suggest

1) each of our four PD members post a PM to bogstandard confirming their intention to purchase
2) each of our four PD members  post say POUNDS UK 100 each as a deposit prior to commencement of construction
3) each of our four PD Members agree to pay the additional engine build costs prior to despatch + consolidated AF where applicable

Who is brave?---------------------Derek

[bogstandard]

Unlike our very eager Derek, I am not one for deposits, or firm orders. I know that from previous experience with my engines, as soon as the collectors get to hear that I am making a batch, they will snap up any that are not taken. I have never had a single one left over.

You never know what will happen in life, so I can never definitely guarantee delivery, but if anyone would like to be considered for having one, please drop me a PM. That will not be classed as a definite order on your part, just an interest. As they come to completion, I will contact you and still see if you still require one. This is just to get an idea of quantity to build, and only that many will be made, so it is no use coming after the start of the build as I will be purchasing the materials only for the initial number. Doing it that way, your anynomity is assured, and if you do want one, you will be guaranteed one of the batch when finished.

I expect the finished price to be between £250 and £300, and rest assured, only the best materials will be used in their construction. That price will also include a displacement lubricator and a purpose designed speed control. So this engine can be controlled with one servo.

I am also looking at fitting a few with a 3 to 1 reduction gear set built onto the end of the engine and if required, a flywheel. These would add slightly to the cost, but not by much, just enough to cover material costs. But bear in mind that both these items would make the engine slightly larger in footprint or height.

Just to let you know, I am not here to sell you engines. If I wanted to do that I would have set up a production line. There are plenty of people making a living out of that in the wide open world, I get enjoyment from making and showing, and maybe at the end of it, get a little bit into the workshop fund for my troubles.

By the deathly silence, it looks like the price has scared everyone away. You wouldn't expect me to become a charity and work for £1 an hour would you? By the time these engines are completed, they will be worth double that, maybe more.

No worries, I have firm orders for two from two other enterprising gents, and I will need one for my collection. So I have three to make, and that works out rather well. So I will get my materials ordered and when the machines are free, I will start to show how to go about making an engine from other peoples plans.

Watch some other space, as I will raise a new post about it.

Hi John,
I would have thought your price was very fair, given your excellent reputation, and quality of work, even more so now you have your new workshop almost complete. But, some always want a Rolls for the price of a Mini. Wish I could indulge and order one, but my resources are stretched somewhat trying to cover my current live steam NZ river paddle tug project. (vertical twin, geared drive as per the original).
Enjoy your building, as I will enjoy following your build thread here. Its a pleasure to see such a skilled craftsman at work, and gives us novices a goal to aim at, even if we can never attain that lofty peak.

Hi Kiwi,

It doesn't bother me one iota, the offer was there.

I would be quite happy making just one for myself, the other two are just a bit of a bonus for the workshop fund. That will pay for a few more cutters that will get blunted in the making of the engines. My small Isreali made solid carbides are running at about £45 each, with the current rate of exchange. But only the best will do. I dropped a large cutter the other week, imagine watching £70 falling onto the floor, then having to go straight into the bin, because one of the teeth had chipped.
People don't realise that there is a lot more to machining other than time and raw materials.

Almost anyone could build an engine like this, given time and resources. Where the experience shows is the much slower growth in my recycle box. In the early years it was quite common to make two of everything just to get one that was acceptable, but not perfect. Now I very rarely have to reject a part, almost all are perfect.

And one more is added to the list now that my order has been placed!

It's stretching the funds slightly (okay I'm skint!), but I can't afford to miss out on the opportunity of owning one of Johns engines!

I just have to find a nice open paddlelaunch to put it in.... I still haven't found anything I really like, so it may be a case of designing my own paddlelaunch.

Eddy
