Thread: Rivers 2.49cc and DC 1cc engines
18/04/2010 10:22:49
Thanks for that help Jens. As a tyro in this aspect of model engineering I'm learning fast but need lots of advice like this. 
 
I do have some fuel as I said earlier but i look forward to mixing my own.  Is castor oil still available from Pharmacies here in the UK?
 
Whatever did we do before the internet gave us this ability to spread knowledge and benefit from such a wide range of experience and advice.  Brilliant.
 
Here are some of the River's components after cleaning:

Here are a couple of pictures of the Rivers, cleaned and re-assembled.  I've uploaded a few more for those who may be interested in these Vintage engines.

Hi,
 
I bought some fuel a couple of years ago intending to resurrect these engines but I never got round to it. (I used to procrastinate, now I can't be bothered!!)
 
It has been sealed in it's original container so should it be ok or will the ether somehow have evaporated?  If so what is the ratio of Ether to fuel as I can obtain some ether from the labs at work.
 
Regards

Hi Ramon,
 
Any tips on the initial setup before attempting to start the Rivers?

Hi All,
 
I should also have said thanks to everyone for your help.  I have taken all your advice to heart.  I want to especially say thanks to mgj for his advice to use boiling water, it was that which finally freed the engine. 
 
I took this route after Ian warned about the dangers of direct heat, it is of course all to easy to overdo these things and cause more damage, I appreciate the warning Ian.
 
I do intend to post more pictures so that you can see the results of your advice.  I am very grateful.
 
Thanks all - I'll be back!!!

Thanks for that Ramon, I'll work on those this weekend. 
 
Your description of the manufacture of the needle is exactly how I envisaged making it except that I intend to stone the final finish in the lathe with a medium and then fine carborundum stone. I will probably support the needle on a suitably sized wood block so that I can apply reasonable pressure.
 
Now the Good News. After a suitable overnight soak in Meths and a morning bath in Mr Muscle Kitchen Cleaner (my wife's preferred version of the Fairy stuff) and a final 1 hr simmer until tender, the Rivers finally gave way to my tender ministrations and turned over beautifully.
 
There appears to be little or no play anywhere but I stripped down the back end to decoke and de-gum etc.  I intend to assemble later after cleaning (using a little light oil on reassembly - I trust a little 3 in 1 would do the trick?).
 
I didn't bother stripping the front end as the bearings and crank felt like new, silky smooth movement with no slop or apparent wear, I feel very lucky.
 
I'll post some more pictures later.
 
 Best regards and thanks for the advice - I'll probably need more when I try to run it

Hi Ramon,
 
Thanks for the pictures and drawing.  i just have a couple of queries.
 
Is the taper on the needle crucial? and
 
What size should the fuel hole in the spraybar be, it looks quite tiny on your drawing, is it to scale, sort of?
 
Oh, I just thought of a third one! How should the fuel hole be positioned when the engine is assembled?
 
Best regards

Hi Ramon,
 
We're off to Tescos for the weekly shop in the morning and I will definitely try to get some of that stuff. I'll let you know the results!!
 
Best regards

I've now created an album,  here are a couple of pictures from it, I hope!!

Hi Ian,
 
I can quite understand your point of view. 
 
"Cherry Red", would that be the nice bright glace cherry that use to adorn every ladies "snowball" or the lovely dark red Morello so beloved of the Black forest Gateaux brigade?
 
"One Man's meat"  etc.

Thread: Rivers 2.49cc and DC 1cc engines
16/04/2010 09:18:50
Hi Ramon,
 
Thanks for the offer of pics and measurements etc, all contributions greatfully accepted.
 
Re the two smaller threaded holes in the cyl head. They are diametrically opposed either side of the main compression screw.  I will post a pic later today when I return home from work.  They are the same diameter as 8ba but the thread appears to be coarser.  Would these be BSF or BSW threads?  I don't want to keep trying various bolts etc in case I damage the threads.  I suppose that I could re thread them with metric but I don't want to spoil the origiinality.
 
Cheers again
 
Terry

Thanks Ramon and all,
 
I will take all your suggestions and try them from the most gentle upwards.  After 35 years I'm in no hurry and really don't want to cause any damage to the poor things, as like Ramon I would like to see these old timers running again.  I never really flew them but just used to run the Rivers to listen to it run.
 
I'm really a tyro as far as ic miniature engines are concerned and know little about them really, so excuse me if I appear a little ignorant about the naming of parts etc and please feel free to correct me if I make any boo-boos.  Give me any engine from 125cc upwards and I can do anything with them, but these little things................
 
The main parts that are missing from the Spitfire (it is a Blue top Ramon)  is the spray bar, needle and thimble etc.  I don't know if I can get standard parts to fit but I'm quite capable of making them if not.
 
Also missing is the pressure screw from the Cylinder head, but that's easy. What I don't understand is the function of the other two tapped holed in the cylinder head next to the pressure screw.  Could someone please enlighten me?
 
 Thanks all for your advice I really do appreciate it and hope that I can reciprocate in the future.  This is one of the best forums I have used over the years, keep it up.
 
Best regards
 
Terry

Hi there,
 
I have resurrected a couple of old engines from my distant past.  Both are diesel engines.  However after approx 35 yrs storage they are both seized.  I suspect the pistons are gummed up in the liners.
 
My query is to those much more knowledgeable than me, is to ask if it is possible to release these by exposing the piston and liner than applying gentle heat to soften the gum holding them?  If not is there a suitable safe solvent I could use to soak them?
 
Also some parts are missing from my DC (I think it's a Spitfire) and I need some dimensions to make new ones and I was wondering if anyone has one of these so that I can get some information, dimensions etc?
 
Any help would be gratefully accepted.
 
Terry

Thread: Lusus Naturae - Contruction details
15/04/2010 07:32:52
Hi There,
 
There is a discussion of this project and it's drawing omissions elsewhere in the Forums in the area of the Model Engineer magazine section.  It's not difficult to find using search facility..
 
There are also updated drawings on this website (at the bottom RH column) of the home page.
 
Most topics are discussed somewhere or other if you look around.

Thread: Perfecto 3.5" Lathe
13/04/2010 23:24:00
Hi Mark,
 
I wouldn't mind a copy of the manual if you can share it.  I have a fascination for collecting such ephemera.  Let me know if we can barter!
 
I have a copy of a Harrison M300 manual which I would gladly scan and share with anyone interested, although it may take some time as I am very busy at the moment with the old multi headed dragon, work.  Somewhere I also have early Boxford School CNC lathe and milling Manuals which may be of interest to anyone in the second hand market.

Hi Alan,
 
I've put up some pictures in the album section of Eric Whittle's original V8 engine which he designed and built, and used as the basis for the ME articles.  I hope that they give you some inspiration.  I have a whole bunch more (plus a couple of videos of the engine operating).  If you would like to see more, just let me know.

Hi Paul,
 
A good start is at lathes.co.uk try here:
 
 
this may be of some help.
 
I didn't realise that the Perfecto was basically a Myford clone.  You live and learn!

Thread: ZA12 - a new option for model engineers?
13/04/2010 12:32:41
Hi Ramon,
 
Brock's response was much as I expected unfortunately,  a lot of industries that used to be helpful (a good example being Foseco foundry supplies) are no longer bothered to help the individual due in part to the more 'corporate' approach these days..
 
However as we have found out through the marvel of this forum the material seems inappropriate for  stressed components in relatively high temperatiure environment. such as cylinder heads.  I noticed on re-reading the original article that the author did point out that he was not sure of the other characteristics of the material except the few that he noted in his table.  Perhaps a bit more research such as we have all contributed to here would have been appropriate for someone writing such an article.  The problems of creep and corrosion seem to be the worst problems although there are others.
 
I just hope that anyone reading the article sees these postings before investing a lot of time or money on producing such components in the material.

Hi There,
 
I hope that you may be right David but there is a difference between making a donation or selling to an individual for experimental work and selling small quantities to a large number of customers.  Many industrial suppliers simply do not have the accounting and administration facilities to be able to handle such custom.
 
I have often been donated small quantities of materials such as silicone rubber mould making materials by large suppliers but they were unable to sell me any in the quantities I need.
 
I look forward to the results of Ramon's enquiries.
 
Regards
 
Terry
