Just when I thought all the parts have been made out come bow fairlead and the .50's. Are you going to do the fairlead in 1/35? Great work Jeff!

When I stopped last year (burned out and caretaking) I had already done the fairlead body Dave. So I tried a 1/16th at SW and it failed but not too badly, mostly around the rear edges and bottom where it tapers. Got that to pass and did a 20th version. I don't know about a 35th, I fear it will look too clunky since I have to raise the whole top and push out the front more for every smaller scale. But I'll try.

The .50's are for Jerry, he's making an acey deucey which didn't use the rear wood grips. But I figure they will also work for the Mark 17 mount. I did find some armory drawings for the grips and brackets and triggers so will probably make some for deck gun use. And some without the fancy cocking mechanism, just the plain rod.

The fairlead's up Dave. It doesn't look too clunky but I did have to reduce the throat a little. The gun is up too, I changed the sprue again to make the parts easier to get loose.

It will be interesting to see how the price change will affect the fairlead since they will be charging for the support wax that will need to fill under the body and inside the throat.

Outstanding work Jeff! The fairlead looks great in the drawing. Can hardly notice any difference between it and the larger scales.

I'm inclined to go with the straight bar charging handle. I've looked at a lot of photos. I see both but the majority seem to be the straight bar. My 105 boat will need a .50 on the bow so I'm interested to see what you cook up.

Jerry and I will put in a group order I'm sure.

Jeff, I had a look at your fairlead, looks very nice but I noticed the sides are angled at 90°, and the correspondent drawing also seems to indicate 45° from centerline; the point is the "5" in the drawing is quite blurry, could be an "8" as well. I did my fairlead at 90° and I have a miserable fit, the bow of my hull being at approx. 98°,consistent with deck arrangement drawings-I know NEVER EVER trust drawings- but I'll have to adjust the angle of my fairlead. I wonder if others encountered this problem also.
The .50s are two little gems...
regards

Thanks David! Without any factual evidence, a guess would be that they could save close to 10 pounds per gun by dumping the cast iron (?) plate of the RSG (retracting slide group) amd just use the plain tube charging handle (a 1992 manual calls it an auxiliary bolt handle for use when other charging methods fail). The drawback is that the handle travels back and forth with the bolt and could easily break bones if a hand slipped off the grips. I don't know if / when they started using the handle straight from the factory but I have an image showing a twin deck gun that uses the handle with a clear shadow visible on the receiver of where the RSG used to be. I plan on making a gun set with the plain handles although the RSG adds a lot of nice detail.

Daniele, actually they are at 48 degrees off center both sides for a total of 96. That's the nice thing about bringing the scaled drawings into my 3D program, I can figure out is that a 3? a 5? an 8?. In this case it was an 8. Luckily I've found the Elco drawings to be very accurate and have imported them into my program for virtually every part. Although they can also be scaled by pixels and used in an image program.

Here's the fit to the hull, the horizontal black line under the yellow fairlead is where the planked hull (minus the guards) would come to a point:



I created the hull from the many many measurements taken from an actual hull in the offset table and the guards by following the molded 6 (if I remember right). I was greatly relieved when the fairlead fit... :D
