ť Topic: Navigation horn correction for PT-157 model
http://www.ptboatforum.com/cgi-bin/MB2/netboardr.cgi?cid=101&fid=102&tid=3217

One of the great things about having other modelers around is that they spot things on your model, that you've looked at a hundred times, and they notice an incorrect detail. Such is the case when Roy Forbes noticed I had the top-of-chart-house-port-side-straight horn (used on PTs 103-138*) instead of the round-housing-curved-horn-on-the-starboard-bridge-wall (used on PTs 139-196 and 314-367*) otherwise known as the 'Federal Electric Company #56 curved bell'*. This is easily confirmed looking at the 'Under Way' photo on the cover of the 'FIRST-UP' book.

Items above with a asterisk (*) refer to information gotten from the PT-103 website and/or email from Jeff Davidson.

The photos below are my update, if you will, to the PT-157 Scratch Book Details book. I love making this stuff as I think you can tell but still for the sake of brevity and not wanting to be a bore I've skipped many of the other interim steps

P.S. The new Italeri model is inspiring in its details and will give me cause to go back and work in some more details for the 157!

Bridge, that was nicely done and an excellent tutorial. I can't believe you were able to cut out that bell horn without it flying off across the room! Thanks for sharing that nice piece of scratch building!

Stunning work Bridge. Now I'll be awake all night thinking about what I could have done if I had a little lathe like that.

Roy;
You probably do have one, that looks like a Dremel tool to me....am I correct Bridge?
Take care,

Here is my 'lathe' and my table saw...all in one. It is a board with a groove with a wide brass straps to hold the Dremel in place. I can easily slide the Dremel into this to setup the lathe/table saw. Speed control of the Dremel is the silver disc on the top left of the Dremel.

On the right is my odd looking looking contraption use for a variety of purposes The contraption has a tongue which slides along a horizontal groove or a vertical groove cut into the board depending on how I want to use it. I use it as a 'fence' when doing cross or rip cutting. I also have epoxied two bearings into which I can slide my finger drill (which you can see) when I can to drill a centered hole in material in the Dremel's check.

When dong lathe work I don't use the 'contraption' at all. I use my X-acto blades, in my X-acto holder, as my cutting tool resting it on my left index finger while working the blade with my right hand. I use the same techniques I learned in wood shop class (45-years ago) on a large wood lathe. As you can see in the top photo of this posting, it can get messy at times so I keep a vacuum cleaner nearby [:-happy2-:]

Bridge, I went to a gunsmith school a couple years ago, and some of the projects were to make our own tools, even though some might have been on the market. That is one of the best lessions I've brought to my modeling. Special tools for special jobs.

Hi Bridge,

Nice little setup small tools for small things, The lath I have downstairs has a metre and a half bed with a 6" swing I find it a little big to do the finer things.

The setup you have would not take much to put together so, now I need to go out and buy a Dremel, I was thinking if you put a small block of wood under the Dremel and one under the "tail stock" you would get a little more swing between the Chuck and the base.

Also a little block as a tool rest?(might save your fingers one day)

Thanks for the Idea now to run it by the wife HA!

But you really do do a bang up job on all those extra things that really make your models stand out, thanks for sharing.

Nice work on the horn Bridge!

Is that a few blood stains I see on the wood?
