A Wallaby of my own.

Getting there Don.....

Now the fussy part....finishing it off without distorting it.


Dave

OK I parted and faced some  1/2 stock  for packing pieces.  I made them a gentle wringing fit with no center pip.

The push in very gently.

I'll clean it all up, and super glue them in, and then bring the pins to 0.4375 and make sure we have no taper ect.

[steamer]

Throws are done!    On to the mains!

....tomorrow......feet hurt.

Dave

[Tennessee Whiskey]

Now you're kicking Skippy  . Did you radius the corners when you turned the throws?  Soak the dogs and carry on.

Cletus

[steamer]

We raced today...."club race"    He won....3 laps up.

I worked on 3 different cars.....1 was ours!..

Dave

[steamer]

Throws done....packing out  NO run out....now I can cut off the throw centers and finish her off....


Lots left to do on this piece....cross drilling, and hollowing out the throws....thread it, taper on one end.....

Dave,
The crank looks great. I'm assuming there is no counter weight to balance the crank?
Art

[steamer]

There is.   They're bolted on after.     The weights are brass.

Dave

I like that crank! There is nothing spindly about it...good and stout.

Pete

[steamer]

Thanks Pete!   The mains are still +.060 over, but the pins are to size  (,4375)

It is a stout crank

Dave

Looking good Dave......

Don

Throws and mains are turned to size.  I have the timing gear side machined, now I have to do the flywheel side.   I'm going to hold off just a bit while I blank out the cam shaft.   They both have a 10 degree taper, and I want to set up and do this once, and make the reamer at the same time so that they fit well.

Probably make two cams just to have a spare.

Hi All,

I'll be documenting this one here.    Hope you enjoy.   Pete (Metalmad) did a full blow by blow at the other place and made a great running engine,,,,hence my name...of my own.
I will be using Bez's castings...they seem well enough...I'm sure they'll be great as one running engine is out there made from them.  I started this at the other site as a "interactive" thread.   That didn't seem to catch on well, ....so although I don't mind input on different ways of doing things....feel free to.....I won't be making it a focus like I did there.   Instead I'll work with the equipment I have and post it blow by blow.  My son is going to be working with me and at the age of 9 is quite young...but he's enthusiastic.    Don't expect any speed records here......    I'm a busy guy.

Dave

Wow....Just looked all the way back at the beginning of this threrad...July 23, 2012....William was 9,  RC racing wasn't even a thought yet....time sure flies doesn't it Dave? Nice to see this thread active again.

Bill

[steamer]

LMAO!    I went back to my original notes on the Wallaby.....from way back....2005!....

I was going to build it bar stock!

Dave

2005? Heck, we were all mere babies back then
