    Mark's Build of Rupnow Vertical IC Engine

    I'm still trying to get the engine completed. Been sucked down by life 😀 Had hoped to complete it last weekend but my wife suddenly decided that she needed a quilt rack made to hang her latest piece on. She suggested PVC water pipe but I figured that would never do - it would sag and...

    An unusual solenoid model engine and last project

    That is a really cool engine. The castings look excellent as does the overall engine. If one didn't listen to your narrative and just saw the engine running, one would swear it was a hit and miss engine. Great job.

    Some more progress. I finished up all the parts for the carburetor on Saturday and I just finished up the main body of the gas tank. Here are some pictures. Don't look too closely at the brazing job on the tank. I just got a set of oxy-acetylene torches on Friday and this is probably the...

    Mark's Build of Rupnow Vertical IC Engine

    I've been continuing to plug away on the engine in the rare amounts of free time I have had. I have some pictures but can't upload them at this time. But I do have a question or two. What do I need other than the points and condenser for the ignition system. I assume I need a coil and...

    Funny, the link to the post that you provided has the exact same info as the link I had - same guy, same pictures, same info. Cool, didn't realize he was on this forum.

    I haven't yet but plan to. Haven't read the link you posted but another site http://www.deansphotographica.com/machining/projects/springs/springs.html suggested about an hour at 450F. I'll have to fire up the barbecue next weekend and cook up some springs. Mark

    Mark's Build of Rupnow Vertical IC Engine

    Yesterday I spent the day in the shop, the goal being to make a jig to wind springs and to make the two valve springs. I've looked at various ideas on how to wind springs on the lathe from various sources over the years but I've never done it myself. I figured the first thing that needed to be...

Life has been busy - a weekend at colonial Williamsburg, sick the next weekend and this past weekend gad to put in 16 hrs of unpaid overtime, two vehicles needed oil changes, one friend needed help removing a prop from his inboard, then has...

    Rupnow Ovehead Cam Air Cooled

    Did you consider machining your own pulleys? vs buying them. I would think them to be far easier to machine then say a gear. Depending on the belt, some have rounded drive "cogs" that would seem might match a ball nose end mill. For square drive perhaps a slightly modified end mill might work...

    Mark's Build of Rupnow Vertical IC Engine

    Got a little bit of work done the last two weekends. Could only manage sneaking a couple of hours last weekend, and a few hours yesterday and today. Basically I finished the push rod - cut the slots, drilled the cross hole etc. I made the rocker arm support bracket and the rocker arm -...

    Mark's Build of Rupnow Vertical IC Engine

    That means I need to get out in the garage and work all night to see if I can build enough parts to get this thing running if I'm going to outrun Herbie... Then again common sense says I need to get a bit of sleep and start working off all the money I spent this weekend.

    Mark's Build of Rupnow Vertical IC Engine

    Here is are a couple of pictures of my engine at Cabin Fever. I had made the valves, valve cages and lapped them in last weekend. I had also made the push rod guide and started on the push rod. Obviously I didn't make my year end goal of having it done nor my goal of having it running for Cabin...

    Mark's Build of Rupnow Vertical IC Engine

    Well I never got as much time to do machining as I expected over my 3 wk vacation. Seems like everyone wanted a slice of my time and unfortunately my wife's grandmother (oma) passed away so she went to Holland so I had to be Mr. Mom as well for the first 10 days of my vacation. My "apprentice"...
