    Hi Cogsy! Yes, I'm going a lot faster than the previous engine. The Tiny in Line 4 had very small parts

    Thank you Neil, I'm really appreciating to build the PeeWee it is a great project.

    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
    IMG_20181224_160422680.jpg

    IMG_20181224_163503829.jpg

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

    More is coming on the intake

    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
    IMG_20190406_193205934.jpg

    Blank ready for the lathe operation
    IMG_20190331_180602764.jpg

    Roughing on the milling machine
    IMG_20190406_193205934.jpg

    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.
    IMG_20190407_174908461.jpg

    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_20190512_164156260.jpg
    They come out perfectlly

    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.

    20190609_215424.jpg

    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
    20190609_231242.jpg

    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

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

    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.
    20190707_181904.jpg

    20190707_191848.jpg

    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.
