    I started this engine a little over a year ago. I haven't worked on it a whole lot, with a summer job and other priorities. This engine gets worked on for a bit then gets put on the back shelf for a later date. Kit was purchased from Shel Pet Models. I will try to post a few pictures every day until it's caught up.

    I started on the base, not a lot of material to remove. I spent a lot of time measuring to be sure everything would be within tolerances.

    There was an "almost finished" example of this engine auctioned at Cabin Fever last week. Quite a complicated beast I must say.

    A couple mere pictures of the base. I bored the block on the mill then cut the bushings undersize and line bored with a long kingpin reamer. The end result was great. The slots for timing gears were cut next after turning out a fixture.

    Here's a couple more pictures, next I built the crankshaft then bored out the cylinders and installed the sleeves. The sleeves were bored undersized .003 and honed to final size after the pistons were built.

    I apologize for not sending any more pictures. For some reason I'm unable to load the pictures because it fails and says the file size is too large. At this time I don't know how to re-size the pictures. Any help would be appreciated. I have been working long days in the shop and progress is continuing. I would enjoy sharing and will, when I get this corrected.

    Dan I use paint.net to re-size and edit my pictures. It's a free download.

    Maury, Thanks for the information on re-sizing the pictures. I'm using a new computer so everything is a major "learning curve". My part time job is definitely interfering with this engine build, but making steady progress.

    I have been working on the heads, it's a bit of a challenge to get all of the dimensions to work out. frisco standard 120190601_135930.jpg frisco Standard 2.jpg frisco Standard 320190630_172754.jpg Frisco Standard 420190630_142210.jpg

    Interesting - Did the pattern + casting + machining for a full size 5" bore Frisco some years ago. Fascinating to see how the designer managed to get the cooling water into around the recesses in the head. Also installed hardened seats into the cast iron head to allow for non-leaded fuel. Engine regularly operating for shows. Another guy i know is restoring a twin and looks like he has to make 2 mirrored head patterns.

    Andy, Sounds like a great and interesting project building a full size Frisco engine. I have seen a few different full size engines running at shows. I enjoy all the moving parts and the sound of the exhaust. The model of this engine that I've seen operate is a pleasure to watch as well. I can only hope that this engine will operate as it should.
