Bob,
Am I mistaken? ??? The more you mill away, the larger it gets :big:


Cheers,
Phil

Dave,

Thanks for your words of support.

Phil,

There is some truth in that, it sure doesn't seem to get any smaller. I may have fallen into the typical amateur designers trap of over engineering. Still it's nice to have pieces I can see without a magnifying glass. Weight wise I suspect it is in the 747 class, power wise, who knows - a very small Cessna. :

Best Regards
Bob

Hi All,

Following on from yesterday, I turned it over and milled the other side

Milled a couple of 45's on the fillets and that's the thing roughed out.

It only needs a heap of blinging - that can wait until after it's finished.

Next week should see a start on the cylinder.

Have a great weekend.

Looking great!

Good WIP as usual,

I thought it looked like it was growing too! ;D

Bob,
I too am a fan of the larger scale engine, simply because I can handle the parts/screws etc. I'm amazed by the talent that can produce the really small stuff. What's "really small stuff"? In my mind, when you take a photo of a whole engine with a US 10 cent piece as a size reference, then you're there. Thanks for the documentation on a really interesting build :bow: :bow: :bow:

Cheers,
Phil

Looking spectacular, Bob.

Kustomkb, Phil and Phil,

Thanks guys for your support and encouragement. :bow: :bow:

It didn't look that big on a piece of paper

Should have used A3

Best Regards
Bob

Great work Bob......Bling away!

Watching the progress of this project is eye opening and inspiring. Until joining this forum, I have never been inside a machine shop with a pro. Thanks for the detail in your pics. I may never attempt a project like this but it does change my vision of what can be accomplished and how to go about it.

Thanks to you and the others who share this opportunity to watch.

Jerry

Dave and Jerry,

Thanks for the kind words, support and encouragement. There are many machinists who are members here, whose talents and abilities are way above mine. :bow: :bow:

I was navy, (RAN), trained and priorities were, does what it's supposed to do and fits where it's supposed to fit 1st, speed 2nd, what it looks like a very distant 3rd. It's the last bit that boxes me, but I am trying to learn from the members here who have the patience to achieve No 3.

Best Regards
Bob

I have faith Bob.....you will do just fine......

[Maryak]

Bob rag wheels ?? what size ?

i have a 6" ( wont go on my 5" rig )

cheers jack

 

[Maryak]

Jack,

This is new 2 me, I have a 6" bench grinder but reading about polishing I don't know if the speed will be too fast or what. Also have a 9" angle grinder.

I can do something with the 6", (I think) : ??? : ???

HELP......

Stitch mop is the name I was given for a rag wheel.

Best Regards
Bob

bling away

cheers

jack

 

[Maryak]

Thanks Jack, :bow:

Better attach the bill as well.

Best Regards
Bob

 

[steamer]

Bob,

Probably too fast on a bend grinder. Slow speed and more torque works better for me.....others may disagree.

bob
it was a left over out of a bundle purchase, so no worries eh
i bought a bundle of stuff for my 5" but there was some 6" and 9 " stuff in the bundle ( oztion)

a RAAM17839 rated 6370 RPM A145 R5 BM4 15.88mm spindle hole , 1984 man. date ( defence old stock)
i've gotten rid of the rest i think maybe a cutoff wheel or two somewhere (9")
