    Straight 6 Cylinder Engine

    Lloyd that is very kind of you to say. I did not expect the tall cut to result as good as it did so I tried it two more times and they turned out just as good. Thank you Ray

    Straight 6 Cylinder Engine

    I forgot the picture all the valves completed from a few days back. Progress the last couple of days was laping in the valves, making spring retainers, and cutting the springs to length. I also installed the piston O-rings. Sorry I didn't get any pictures of those processes but here are the...

    I installed the valve guides last night and today extended the intake and exhaust ports into the guides. Then tapped them 5/16 X 24 threads. I got a start on the valves themselves. Thanks for looking Ray

    Straight 6 Cylinder Engine

    I want to thank everyone that left suggestions on the lettering. I have done this before on dials and art work but I was just not deep enough into the aluminum to hold a color on this plate. I have resurfaced the plate and shined it up for now I will leave it like it is. I enlarged the water...

    Straight 6 Cylinder Engine

    I made a new lower pulley to speed up the water pump and enlarged the diameter of the in and out brass nipples today. It did help but not as much as I had hoped. The water pump inlet port may be too small and I want to make a way to vent the cylinder cavity of any trapped air maybe tomorrow...

    Straight 6 Cylinder Engine

    I thought I would give the engine a name. I am going to try and enhance the name so it shows up better. Do you have any ideas? So anyway I cut out the side plate and a gasket for it. I want to test the water pump before I go much further for flow and leaking. Two things I need to change are...

    Straight 6 Cylinder Engine

    In January of 2022 I finished a twin engine called Two Timer. This was the only engine that I built that had an active water cooling system. It worked very nicely and kept the engine temp down on long runs. But I have only ran the engine with water in it 6 times since it was completed as the...

    No I will be adding o-rings later on. Thanks for the reply. Ray

    Straight 6 Cylinder Engine

    Yes and the moon was in the right phase too.;) Time to get this engine to stand up on it's own. I have thought about this for some time and drew up a couple motor mount designs but I didn't care for them . In the end I will go with the same type I used on my 4 cylinder engine only a little...

    Straight 6 Cylinder Engine

    I am kind of straying off course but I thought this would be a good time to see if i could make a cylinder head from the piece cut off earlier. If you remember I stood the 12" long piece straight up in the band saw and it cut straight and true. So why not try it again and cut off a 5/16 thick...

    Straight 6 Cylinder Engine

    Since things are fitting properly so far I thought it would be a good time to spot drill the block for the head bolts. Then over to the drill press to finish drilling the holes to depth. Then tap 24 holes 6-32 and glad to report all went well. I was sweating that last hole as that's when...

    Straight 6 Cylinder Engine

    Turned out 6 pistons but forgot to get a picture. This is the setup I used for the rod end slot 0.750 deep. I installed brass bushings in the rod ends for the wrist pins. All six done and ready for the wrist pin holes but not today. Thanks for looking Ray

    I spent most of today drilling, taping, sawing, and reaming the rod ends. I was rewarded with this. And everything fit !! Thanks for looking Ray

    Straight 6 Cylinder Engine

    After sawing through the bushings and rod caps I will enlarge the rod cap bolt holes to fit the size 40 screw and tap the rod holes 4-40. Now when I reassembly the rod caps there is an egg shape on the inside of the bushing but the inside of the bushing needs to be reamed out to 7mm and that...

    Straight 6 Cylinder Engine

    Working on the connecting rods today. Milled out slots for the 4-40 rod cap bolts. Drilled the holes for the 4-40 screws. Always trying something different I ran across these from McMaster Carr and will give them a try. "863iron-copper bearings are also known as Super Oilite® bearings" I...

    Straight 6 Cylinder Engine

    On the last pass I just hold them down with my finger. I am very conservative with depth and speed so the parts rarely get hot. Thanks for asking Ray

    Straight 6 Cylinder Engine

    I decked the cylinder block to get everything nice and level again. It looked so pretty I couldn't help my self but had to paint it. Used Allis Chalmers orange. What do you think? Also cut out 6 rods on the RF31 clone CNC. All in a row. Thanks for looking Ray
