YTL-710 in 1:10

Sharp, it's the attention to those little details that really make it look good.

I really appreciate the work that goes into super miniaturization of some models... and I'm glad someone else does it! That's a nice feature of this big model- lots of room for my fat fingers to work in, lots of room for mechanical installations. Like the steering.

I want the big 4" ship's wheel to spin when I move the rudder. So I set up a 3:1 gear-up drive from a servo in the forward trunk. But rather than using gears, I set it up with chain drives... 1/8" pitch miniature nylon chain, which runs on sprockets from ServoCity-- you can get sprockets that attach directly to the servo, cool!

The steering pedestal is similar to what I've seen in some of the ST tug photos, it will get a compass on top later. But you can see how I used pieces of 1" square aluminum tube, bronze bearings, and the sprockets and chains to build up the pedestal. A shaft sneaks forward and into the forward trunk, where another chain drive connects to the servo. The servo of course will be Y'd into the rudder signal.

The whole mechanism runs smoothly and with little friction. Sweet.

Installed the search light. Using similar hardware as with the wheel, I set up a 1:2 drive to obtain a �90� motion with a normal servo.

The light itself is machined from PVC barstock, with reflector, lens, and high intensity LED from a flashlight. It's about 1" diameter. Needs a little more detailing to look like a real lamp- see the real examples below.

Very well thought through mechanics and detail .

Lots more time consuming stuff this weekend that leaves me with surprisingly little to show off... but progress is happening, I tell ya!

I hoped to have a bunch of etched brass parts to show today... spent most of the day on the process (a royal PITA)... involves a laminator and "toner transfer paper" and an ironing board when the laminator's not up to par and "foils" (long story) and brass sheets and had to buy a hot plate to keep the ferric chloride warm and there's a mess all over and my ferric chloride is spent and I don't think Radio Shack carries it anymore, so the parts aren't finished yet... but it's real neat when it works. Th etchings will go on the mast, and handrail brackets and such.

Did start with some cast resin parts, the hinge and latch hardware for the hatches. And spent much of yesterday applying "rivets" around ports and windows... yes, those are pin heads for the most part, but some are from my Starwoods Rivet Kit (e.g., dots of glue applied by a syringe), where I didn't want to take a chance of drilling through the wall to the interior.

OK, maybe a couple etched part pics.

Hey, do you sign your work? You should! At least put a plaque in the model.

Love the louvered grill on the back of the stack.

A top quality build , I like the hatch and the detail work on the stack.

Thanks!
For size reference- those stack pipes had to be turned from 1" PVC bar stock...

Lots of stuff in process right now... here are a couple updates...

Pat - I rarely would build the same subject twice, but after seeing what an excellent job you are doing it makes me want to revisit the YTL. But there�s a FFG keeping me busy for now. Maybe after the ten other boats waiting for my �free� time

The mast is all brass, some 30+ solder joints. Base is 3/8" tube. The lamp platforms and ladder rungs are all home photo-etched (rungs are flame-cut parts, not round stock); see my P-E how to at:

I'm also working on the lamps with their lenses, which are about 1/2" diameter... more later!
