    The restauration of a Nova 1 4,5 cc model diesel long stroke engine

    “Later I learned that this is done professionally, the process called "nurliseren" to give worn out pistons a second life.” While racing motorcycle flat track in the late 1960s, I was on the road in California, and had pushed my piston replacement too far in my Harley Davidson KR, and developed...

    Thumper--a 1 3/8" bore i.c. engine

    Oh, one more thing I’ve learned the hard way. Even though you didn’t mention it for this setup, never use a strong magnet to secure/align parts for TIG welding, even outside of the weld area. I got lazy one day and thought I’d give that a try, and what a complete wreck that turned out to be...

    Thumper--a 1 3/8" bore i.c. engine

    I think that’s a wise choice Brian. Distortion of the blades is very possible, and there goes all of your hard work and accurate machine setups. Since there’s almost no load on the fan blades, the stresses involved will be minimal, and a secure tack weld at the leading and trailing edges of...

    Thumper--a 1 3/8" bore i.c. engine

    Brian, how about if you remove the chuck from your lathe and use it as a fixture for tack welding? The reason I suggest welding away from your lathe is that your TIG welder will initiate its DC arc with a high frequency pulse that can be VERY harmful to electronic devices. When I’m welding, I...

    Introducing ... the "Steel Webster"

    Thanks for the detailed build Awake. The Webster will probably be my next engine as soon as I finish my Kitchen Sink Engine. I wish I’d have picked the Webster for my first IC engine instead of the Henry Ford replica. That leaky low compression S.O.B. Is causing me to pull out what remains of...

    Thumper--a 1 3/8" bore i.c. engine

    I like your method for spacing during the crankshaft pressing Brian. Knurling come in handy when stock doesn’t fit for crap! Many, many moons ago, when I was a young flat track racer, the Harley KR I was riding developed excessive piston slap while out of town. We knurled the piston skirts by...

    Introducing ... the "Steel Webster"

    One bit about which I am quite uncertain - my decision on how to keep the wrist-pin from floating out and scoring the cylinder. As you can see in the plans, I chamfered the outside of the wrist-pin holes. For the final installation of the wrist pin, I cleaned it all well and used a bit of red...

    Introducing ... the "Steel Webster"

    Awake, I don’t see where you locked your clapper down for the internal keyway, or am I mistaken? If you didn’t lock it down, we’re there any problems with the return stoke, or was there enough clearance for your tool in the early stages of the cut for clearance? I need to do a similar...

    Thumper--a 1 3/8" bore i.c. engine

    Brian, a quick question if you have time. What carburetor design do you most commonly use? I’ve been looking at Chuck Fellowes’ design for an upcoming project, and wondered if you have an opinion? thanks in advance, John W

    Thumper--a 1 3/8" bore i.c. engine

    Thanks Brian, that’s what I’m currently using from Leon Ridenour’s instructions. With a two ring setup, I’m hoping my minor deviation in ring groove width on the bottom ring (.002” oversized) won’t impact the compression enough to impact my getting it to run. John W

    Thumper--a 1 3/8" bore i.c. engine

    Brian, et. al., I am about 3/4 of the way through my building of the Henry Ford kitchen sink engine (my first IC engine from Mr. Ridenour’s plans) and already considering a design of my own. My question to Brian, who has a significant amount of design experience is, does there exist a formula...

    Thumper--a 1 3/8" bore i.c. engine

    Remember that aluminum requires 10 to 30 percent more heat to weld it. Additionally, even one day’s worth of oxidation can wreak havoc with your welding, as the melting point of the oxide is higher than the melting point of the aluminum itself, which means you could blow out your aluminum...

    I like that A LOT! Quite the nice down scale of a great project. Any chance of seeing a video of it running? John W P.S. I’ll bet Dr. Senft would really appreciate it too!

    Thumper--a 1 3/8" bore i.c. engine

    I’ve been doing similar stuff lately with components that are mirror images of each other, and have a lot of success using super glue as the bonding agent. When I’m done with the work, I either use a heat gun to separate the pieces if large, or an acetone soak for pieces that fit into one of...

    Thumper--a 1 3/8" bore i.c. engine

    Brian, If you’ve got the room, keep your Lincoln BuzzBox as a backup so you don’t have to tear down your TIG unit for a quick AC stick weld job. I kept my Miller Thunderbolt for the same reason when I upgraded, and while a DC welder is preferable for mild steel stick welding work, the...
