Hi Guys,

Well it's been a week since M10 burst into life. Thanks for all of your remarks in that thread. :bow:

I cleaned and oiled the lathe, stripped the mill down and was pleasantly surprised by the minimal amount of grundge under the tables and on the feed screws. Oiled and greased it up and put it back together. The floor under the benches and machine tables was another matter, I retrieved 10 kg of metal muck and mess from these areas. ::)

So what's next - the Hit and Miss Engine my daughter gave me the plans for.


After a week without taking photos and thinking how to caption them.... I was bored so here we go yet again.

The Idiots Guide to Hitting and Missing.



A hunt around revealed a lack of suitable sized material for major components such as flywheels and crankshafts. Up to this point I hadn't fully appreciated how big this model is.


This resulted in some serious grovelling at my mates shipyard to obtain some 3/4" and 5/8" plate for the flywheels and crankshaft. Plate no problem but more grovelling to get it flame cut to manageable sizes. ;D ;D

The major lumps.



I decided to make a start on the base components.


And now photobucket is down so I will finish this later.

Photobucket is back up so on with the show. ::)

Making a right angle datum on base piece 1 for marking out/off.



Base1 ready for shaping.



Shaping base1.



Best Regards
Bob

Bob,

Really looking forward to this one. It is my favourite type of i.c. engine without a doubt. I had been known to stand at the ropes watching these things for hours at shows from about the age of 10! They are mesmorising.

I will definitely build 1 at some point!

Thanks Tony, Yep I managed to crawl under everything. I hate 6BA nuts disappearing into the mud, blood and beer. I am amazed at the speed they become invisible. :eek: :eek:

Got a little more done today.

As the base is a fabricate and weld item, I put away mikes and verniers and settled for good old split the line. ;)

Final Cut Base 1.



Completed Base 1.



Base 2 x 2 Ready for marking off.

Rob,

The base is an all welded construction. You've just reminded me I need to buy some more disks for my angle grinder. :eek:

I once heard it said that the only difference between a bad welder and a good welder is a good angle grinder - need I say more. ::)

I have been pondering how best to get a decent profile on Base pieces #2. ??? ???

My solution was to draw them in CAD and using all those wonderful snaps and curves and things profile it out.

I ended up with this.



The idea is to glue this to some sheet metal, carefully cut it out and scribe around the curves onto the base pieces.

Best Regards
Bob

sounds like a plan Bob, just out of interest how long are the sides your going to profile?

Had a story about hand filing related to me just the other day. Something to the effect that the fellow recalled his first day in vocational school when he was instructed to square up a block of steel about 3" x 4" x 5" with nothing but a file. After a few hours the instructor inspected each students work and tossed each piece in the scrap bin as he went. When asked why he was discarding such an investment in time and effort, he said that the only reason for the exercise was to evaluate the students work ethic. As you can imagine, a large percent of them kicked, screamed and complained the whole way through. Spoke volumes...

jthulin,

Same thing happened to me in my final year...Instructor says here I'll show you something and then runs my gauge through the rolls with my saw and boom...he says ooooops...I say well that's a pass...he says fix it. stickpoke There ya go another day in trade school. had it fixed in an hour only because I had made three gauges and had a spare.

Oh don't want to steal the thread.

Keep up the good work :bow: Bob. :bow:

Regards

Philly
