      I built this model as a young lad with my father's help at times and have been intrigued by it ever since and always wanted to scratch build Tommy Ivo's Showboat 1/8 Scale it. Building four engines from scratch just seemed a task that I was not ready to tackle. Recently I have been extremely busy building, designing and developing model ship kits fro M.E. and have been looking for a personal project to keep me from going KNOTS. Anyway I came across a site offering a 1/8 scale Buick Nailhead cast resin Tommy Ivo's Showboat 1/8 Scale engine and after a little discussion reached a fair deal to purchase four engines knowing that some parts would require significant modifications.

      In doing research, I discovered that the Showboat itself underwent changes as it evolved to its final configuration as seen above along with an image of it in its earlier days with no body. Could very well be test runs. I also discovered on the H.A.M.B. site photos posted by the original builder and the replica builder which will be my reference resource. The Revel kit while in its day a good model but has a few major discrepancies the greatest being the oil pan configurations. I have also seen the die-cast model as well which is also creative in some details. Working from photos only and my own research I may also have to get creative with some small details.

      The initial build challenges I for see are the alignment of the four engines and the centerline of the 14 exhaust pipes; two point down on the left bank of engines. Hopefully, Mr. Geometry and Mr. Physics will help me along the way.

      First will be the clean up, drilling and milling of the cast parts. Since I have not done any extensive work with resin Tommy Ivo's Showboat 1/8 Scale I will now have a new learning experience and this will be a mixed media build. If anyone out there has any information or detailed personal pictures please share I will need all the help I can get on information.

    Roger, thank you for the cable and yes I to hope it can get here as well. I to have learn the hard way and then she will tell me what I should have done. She is fantastic, she hammered out a cowl for the Sopwith Camel one piece 3” in diameter with full return using one piece of aluminum.

    While waiting for my order of brass to come I made the seat back with a piece of .016" sheet I had. I countersunk the hole for 0090 flat head screws per the original.

    Once the brass arrived I was able to start the body work which consists of four parts; belly pan, forward cockpit, rear cockpit and rear deck. I started with the belly pan since it was one piece; as with all the parts I made a cardstock pattern, cut a brass sheet part and annealed the piece by heating with a propane torch and quenching in water. The trickiest part was matching the holes to the mounting brackets on the frame.

    Next came the rear cockpit which consists of three main component parts. The bottom came first with a couple of notched saw cuts for a slight bend. Then at the rear several notched saw cuts to form the curve. The challenge for all the body parts was to maintain the .020" wall stock with butt solder joints. Both sides were bent to match the frame mounting points. The bottom then had a cut to index the bottom with the push bar from the frame. Then came the indexing and drilling holes to attach the rear bottom to the belly pan with threads tapped into the bottom part. I then made the side cardstock pattern to be used for both sides. The challenge here was match the opening around the brakes. Edges were formed to match the frame and the bottom edges cut to match the curve tangent on the bottom part with a tight joint fit for soldering. See the picture showing the inside of the joint line. Once the both sides were soldered together I then made a wood buck to help form the tight bend. Once the bend was done I then added the flanges for the rear deck to be attached to and will have threaded holes in it. I then added to pieces of brass to edge thicken the parachute opening to simulate an edge return; a 1/32" rod was added to the top of the bottom of the opening to replicate a tighter bend that I could not achieve and filled the curve with 50/50 solder, just some old time lead slinging.

    The rear deck is a small part with a series of straight bends that were formed using a 3-1/2" hand seamer. Holes were drilled to match the side flanges and the seat back which really strengthened the whole assembly. I then added glazing putty Tommy Ivo's Showboat 1/8 Scale
    to smooth out curves and pits from the lead slinging.

    Next will come the hard part, the front cockpit.

    The front cockpit was a bit of a challenge with multiple curves and small attached parts. Patterns were made for the top and side parts and transferred to brass sheet and cut and annealed. The center crease was made by first folding the cut part down the center line and then back out to form the upper curve. Then saw cuts were made at the bend to ease the bending process and the parts was slowly bent to form the lateral curve. Both forward edges were then hammered on the horn of an anvil to form the front curve tapering to the bend towards the frame parts. Then adjustments were made by hand to fine tune the fit.

    The two sides were then formed but the parts were only annealed along the edges to be formed using the axle and front frame as fixed references for forming. They were then cut and adjusted to match the top edges. All the parts were then tack soldered to each other; then the joints were soldered with Staybrite solder for strength and 50/50 used as filler for surface matching.Joints were then filed of excess solder and then sanded with 150 grit sandpaper.

    Next were the small parts for the front side frame covers and then the engine bracing rod covers were made using 50/50 to form the radii. Finally the right side was saw cut to make the curve surface that will mate with the firewall.

    Then all parts were glazed as needed, primed, sanded and painted Satin Black on the inside and Banner Red on the outside.

    Truly remarkable Ken! I know how much time it takes to document a build so a big thanks for that.

    Thanks George, yes it does take a little time to document and post and hopefully it will help other builders learn and develop their skills.
