Economy Hit & Miss Engine
« on: February 21, 2017, 06:32:23 PM »
.

Had a delivery today from 'The Engineers Emporium' in the form of castings for the 1/2 scale Economy hit and miss engine.  :)

I did not realise until I phoned them to order that they do this engine in either aluminium castings or all cast iron. I went for the all cast iron set. Adrian at the EE explained to me that they were short of the CI casting for the hopper for a few weeks as they are waiting for a delivery from the foundry but could have that casting in aluminium if I wanted. I asked him to send what he had as it will be a while before I get to the hopper and to send the CI one on later to me. I should add that they do many fold the number of castings for engines and general items that they do not have upon their website.

Castings seem on inspection to be of very good quality with nice edges and corners, true to shape and casting halves very well positioned. Initial impressions are although I am yet to start to cut them is that they are of better quality than the ones I have had in Stuart kits - Bit of surface corrosion on them when they have been in storage but that is of no matter.

Bound booklet of drawings is very impressive with each part having it's own page along with exploded drawings. (probably 100 ish sides in total) The drawings are in metric. Personally I prefer to work in imperial. ........ But that's just me.

















It's a bit of a lump as you can see and I may have to get a bit creative when machining some of the castings. The supplied raw castings so far weigh 36kg (delivery guy did not seem happy) which is about 80lbs. 13kg of this is the flywheels. Added to this needs to be the weight of the hopper, conrod and crank. Then minus a bit from machining swarf. So will probably weigh about the same as the similar sized Galloway engine (90lbs according to Galloways specs)

You got a set of these Jo to fondle Jo.?  ;)

Castings look nicely aged Nick. I suspect these won't take much fondling and are ready to feel a nice sharp tool. 90lbs. is a pretty good size old boy. I'll be following along.

That is a big boy Nick but I agree the castings look well done. I hope they will machine as nice as they look.

Nick, regarding the possibility of chilled castings that you were asking me about earlier, the most likely places that I can see where you may get an issue are the tops of the two posts on the head and the two ends of the small rocker casting. Test them with an old file first rather than blunting a milling cutter on them.

That's not a small engine.  Will surely be following your progress.  Interested to see the setups for the large castings.  Nice to see the instructions are in metric.

I must pace myself... I have already acquired one set of castings this week  :naughty:

Well since the new year's resolution is already broken (or was that last year's resolution  :thinking:), go for it Jo. Surely you have room for one more casting set at least  :mischief:

Not this week  ::)

And if I am buying a new set of castings it is sporting to haggle face to face :naughty:

go for it Jo.

Bill

She will Bill. .............. She it seems can resist anything except temptation.  ;)

Just a matter for her to decide if she is feeling strong and buys the CI set or the aluminium version.

Nick you are forgetting the one major factor that means Jo won't be buying these

She won't be able to get them as cheaply as she likes as Adrian can't be taken advantage of like her usual supplier can :stir:

Besides its just another side rod engine ;)

That might be your experience  ::)

It is true it is another Horizontal H&M and I already have 3 of those and there are another 2 available at my supplier's  :thinking:

The real killer is I am pacing my spend this year ready for my retirement  :mischief:
