Thank you Steve and Neil!
Steve I'm being able to work a couple of hours every day and some full weekend. Thanks for your help on this project.

My last work of the year on the PeeWee.
I have finished the intake manifold. I copied Michael process, was really strait forward.
It was not difficult to machine but, was really a work of patience!

I started machining 45° on both end and side to the largest lenght

Removing the material that will form the bolting flange

Moved to a vise with angle adjusting feature and set it to 45° to form the flange

Hello People!

It has already passed several months since my last post on the PeeWe progress. Almost half year. The available time is short.

Here is some info. about the progress.


The crankshaft

Blank ready for the lathe operation

Roughing on the milling machine

IMG_20190406_225057192.jpg
IMG_20190407_120238724.jpg


Ready for the main bearing. To avoid warping, I used a bolt and nut to fill the offset space
IMG_20190407_165323912.jpg


Now is the turn of the ends. I used the lathe fixed steady as much as possible
IMG_20190407_174900802.jpg


More to come.

Some more details of the Crankshaft on the lathe.

Turning the ends
IMG_20190409_204606460.jpg


Machining the counter-weights
IMG_20190409_221901915.jpg


Checking out how it fits on the block
IMG_20190410_214750255.jpg


IMG_20190410_214846247.jpg


Before turning out the ends, what would cause to get rid of the center holes, I grinded the jornal to the final diameters
IMG_20190407_200346830.jpg


Back to the lathe for a skin pass on the FlyWheel for perfct balance
IMG_20190411_212138404.jpg


So this finish the hard part of the crankshaft.
Still needs to grind the ends.

Thanks,

Edi

Preparing the blank for the connecting rods.
This is the bottom portion of the connecting rod. I bored all the bolt holes including the small lubrication ones
IMG_20190419_095407296.jpg


Than I bolted the lower portion to the upper one.
Ready for the profile
IMG_20190419_124018952.jpg


Finished connecting rods. I made a program on the SprutCam

More to come on the bearing bushings

Hi to all!
As I do not like the process of soldering two halves of bronze for the bushings, I turn two complete bushings than machine out to the midle of the diameter so, we have two perfect halves

Machining out to the midle of the diameter
View attachment 109645
IMG_20190512_103515990.jpg

I made a kind of collet to machine the inside diameter
IMG_20190427_230233423.jpg

IMG_20190512_164156260.jpg

They come out perfectlly
IMG_20190427_235752368.jpg


IMG_20190428_162218561.jpg


Fitting test was perfect
IMG_20190427_235257402.jpg


Running freely and no play

The lifters made out of 12L14 steel

Nice Job Edi! Put two bearings on the rear of the crankshaft. Spot one flush with the outside of the block and the other on the inside of the block. Make them as far apart as you can get them. That will be a great support for the flywheel encase there are any issues with the flyslug being out of balance a little. Little sucker is heavy.
 
Hi to all!
Thanks Brian.
Steve, yes I added one more bearing. I had seen your recommendation in another thread and ordered one extra bearing for my PeeWee.

Everything was running smoothly than, I moved the block to the lathe for breaking in. I filled with a little excess of oil to perform the breaking in. Now I will remove the oil, Clean everything and fill with the right level of oil and run a few more minutes. I also tested the cameshaft. It was running OK and moving the lifters freely

I think that in one more month I will be able to make the first start.

Tks,

Edi

Here are some more pictures of the progress. It is not in sequence of construction.

Turned the valves

Grinding the valve stem using a adapted manual grinding o the lathe tool post
IMG_20190518_121747954.jpg


IMG_20190516_212934136.jpg


Cutting off the the rings. I used a 1mm wide cut off tool
IMG_20190503_221117095.jpg



Test of the ring on the piston groove
IMG_20190503_222706432.jpg


I separated the rings using a cut off plier used on electronic shops
IMG_20190503_223038299.jpg


IMG_20190504_171858230.jpg


I have used Bob's method to provide the spring effect on the rings.

For the Liners lapping operation, I used a brass lapping bar
IMG_20190501_162243444.jpg


I have used a diamond paste for the final finishing. The inner surface come out very smooth

IMG_20190503_195035941.jpg


In order to assure the hight from pin center line to the top of the piston, I used a long pin with the same size of the hole as a stopper

Hi to everybody!

A question/help for those that have built the PeeWee.
Did you guys face the same problem shown on the photos below? The fan is interfering with the center line of the crankshaft consequently hitting the starting shaft.
What did I do wrong? I already checked the drawings and the fan diameter is correct as well as the center line distance from crankshaft and fan shaft.

Comments, hints, explanation are appreciated.
Thanks in advance,

Edi
 
It appears that the dimension from the centerline of the crankshaft and the centerline of the fan boss might be off. The radius at the top of the timing cover and the boss for the fan should not be concentric. The fan boss should be shifted up from the cover centerline about 0.200 inches. It appears from your earlier photos that the boss did not get shifted up.

Shorten the fan blades.
