Update]For those not following the

Update]For those not following the thread on SubPirates, I have had some input from fellow builders on the sail for this particular sub. I've remodeled it in CAD and came up with a design that uses pretty much all of the suggestions I received and some flare of my own. The following continues with the building of the new sail and more..[/i]

This evening I did some more real work on the sub. I took the plans of the new CAD work I just finished and put them to use. Using the same top/side view technique for cutting out the last sail, I cut out this one and right away it looked better. A much better fit, both in style and scale. I gave it a quick few scrapes with some 220 grit sandpaper to take off the hard edges but overall it didn't need much.

I also cut out a new set of dive planes. The other ones I made were too thick so I went with a thinner balsa plank and re-cut them. I gave them a quick sandpaper scrape as well.

After I had done all that, I thought about doing the icing trick again but thought better of it. I'm not the greatest at being conservative with that stuff yet and my parts are only as big as one of my fingers at best so I didn't want to push it and ruin them again. That and I didn't want to have to sand them down all night. No thanks! Instead I tacked on a couple layers of 3/4oz glass and resined them. They are curing now and should be ready for finish sanding and some touch ups later. Once they're done I'll detail them and mold them for casting Alumilite parts much like I did the stern planes.

Here are some pictures... the most important things I know... you just glossed over the wordy part didn't you?? uh huh! gotcha! LOL

I then slipped the med. tube inside one of the large tubes(rubbed with mold release on the inside) and placed the small tube centered on the flat surface of the med. tube. I secured the small tube with clay on the inside so it held firm. The I poured a little more Alumilite around the crevase that was formed bewteen the large and small tubes and let it set.





After a little gentle persuasion I was able to remove the combined tube from the larger tube and was able to continue with my plan.

I then pulled out my new drill press and cored out the center of the Alumilite wall that had been formed in the middle of my tube... how'd that get there????? I was a little off center and ended up filing the internal edges for a clean transition from med. to small.





After that was done... I pretty much called it a night and felt satisfied to boot.. I be happy! Here is a shot of the motor and end caps on just for show.



Oh and here is a pic of my new tool... very nice!

I started work yesterday on getting the wires through the first endcap. Basically I drilled a small hole, fed the wires through and sealed it with Alumilite. Not a bad way to go and it's nice and neat.



I worked on the motor mounts next and started with a small bracket plate for the motor/gearbox to mount to.





Two brass rods were cut and bent then to go around the motor and secured to the first endcap by drilling a couple small holes in the endcap and then CAing them into place.

After getting that together I soldered the wires to the motor and secured everything in place so I could fit the drive shaft pieces.





I had cut and drilled two of the support brackets in case one broke while I worked. Fortunatly that didn't happen so I had a spare bracket. I used that to determine where to drill the hole for the drive shaft seal. After drilling that hole I CA'd the seal in place and proceeded to pour a little Alumilite fitting around it for extra hold and seal. overkill.. maybe.. oh well...



With that all complete I put it all together and now I have a complete motor WTC... on to the Main Electronics WTC.....

Resurfacing

*stale smelling, odd colored bubbles break the water briefly before an odd shaped bald guy breaks through into the Inside Passage's calm and cool waters*

Hi folks! It's been a long while since I've been here (ok.. three years is a little longer than a while) but I'm finally trying to resurface and get a little more active behind the work bench.

I have a number of pics from bits and pieces of work I've done over the last couple years on this sci-fi scratch build.

I have to admit, it hasn't gotten much further than you've seen and it's still not wet... not even close.

What I have done is this..

- Taken a mold of the master
- Partially successfully made one copy and assembled parts of it (sadly the only one that will ever be made.. Subpirates.com members may remember the mold mess I made back in '07)
- Painted the master model and almost completed the static build of it.

But! There is hope as I have put up a workbench again and slowly I'll be continuing the build right from where I left off.

Hope to sail with you folks once again if you'll have me.

Cheers!
Dan

At last I have a moment to post some catch up pictures.

For those who have frequented the Subpirates site for the last few years, most of these photos will be repeats from when I was a member and posting there regularly.

In order (I hope), you'll see the mold making process minus the messes I made in the process.

First - The making of the of the top and bottom molds.





Second - The hack job version of trying to make a copy of the top side. When I first posted this 2 years ago I got chewed out for my technique (with good reason I learned later) but it was my first attempt at it and I learned a great deal from it. Mistake or no, I learned and that's what mattered to me. The molding of the bottom side went much smoother because of what I'd learned.

From this I learned how to layer fiberglass a little more properly, repair bad castings, effects of filler and a whole bunch more that's been really useful.

So, here is a sampling of some of the work from casting to where it pretty much is today. As you can see in the last photo, I've done some finishing work on the hull to blend the lid and main body together but since then I've not done much. I intend to remedy that.









What no one has seen yet is my paint job on the Static Master version of the sub. I won't be taking anymore moldings of it so I decided to finally do it up and get it so I can mount it on my desk at work. Only a little left to finish on this and it will be done. Mounting of the prop and rear planes really.. maybe one day I'll add lights and a moving prop but who can tell? It'll look better with a shot of clear coat too I think.. take away some of the flatness of the paint.

Oh.. yeah.. Made in Canada so of course it's fully labeled with Canadian markings.



That be all for now..
