She is, indeed, a work of art.

Response by RNinMunich on the 6th Oct 2017

She is that. nice job 👍
Bit different from her namesake though 😉
"USS Sea Hawk (SP-2365) was an armed motorboat that served in the United States Navy as a patrol vessel from 1917 to 1919.

Sea Hawk was built in 1917 by Herreshoff Manufacturing Company at Bristol, Rhode Island, as the civilian motorboat Herreshoff No. 319. The U.S. Navy acquired her from Arthur Winslow of Boston, Massachusetts, on 20 October 1917 for World War I service as a patrol boat. She was commissioned as USS Sea Hawk (SP-2365) in December 1917."

Thank you, i genuinely didnt know that,there was a 1958 movie called USS Seahawk but that was deffo a frictional sludgemarine.
I was going to call it USS Penguin, but I just couldnt get the nose to look like a chocolate biscuit!

Response by RNinMunich on the 6th Oct 2017

Hi Mactin, there was also a 'Seahawk' in the Star Trek / Wars saga!
Shame about USS Penguin, would have been a tasty boat 😉
BTW: penguins are my favourite animal. so funny, or imperious like the Emperor penguins. 👍
Didn't know about the film either, when I think about sub films Operation Petticoat comes to mind! How about doing a pink one!!!?😲
Keep up the great work, Cheers Doug 😎

PS: USS Enterprise, CVN 65, 'played' the part of USS Seahawk in the CAG TV series! 😎

Looks good. I like the paint job you have done.

Response by Scratchbuilder on the 8th May 2017

Many thanks.Always trying to improve this skill.Real rust from nails left in water for ever I find the best then painted in satin varnish.Bill.

Response by John on the 8th May 2017

A very effective method I will give it a try.
Thanks,
John.

I want one!

Hi
How does this work?
Edward

Response by mactin on the 22nd Mar 2017

Hi Edward, Its a fine balancing act of electrolysis to hydroide gas, compression then ignition but utillising vacuum formation as an assisting force to the power stroke so effectively making it a one stroke which sounds odd.still in development ive tried turbine,oscillator pistons and hydraulic recoil as end movers but the best seems to be the straight reciprocator. Its scary,how the hell can they tax water??? cheers Neil.

Hi Awesome engine, You better get it patented!

Response by Scratchbuilder on the 9th May 2017

Hi.Excellent boat.Do you have a dive tank fitted and if so what make.?
Thank Bill.

Response by xtramaths on the 10th Dec 2016

Nice engineering, have you looked at straight air tools for gearboxes? plenty of those around in your area perhaps.

Response by mactin on the 20th Jan 2017

U35... Finally done! 2 Months this one took! 3 Ballast Tanks Clockwork Timer for the compressed air system clockwork motor for the coaxial contra rotating tandem props. Maximum time on the bottom 1 hour. clockwork tinplate submarines are great fun!

Response by jarvo on the 9th Oct 2016

HI Neil, Welcome to the forum, loved your site, and your humor, great work on the subs, how long a run do you get from your clockwork motors? also do they only submerge under power? surfacing once the run down???
Regards
Mark

Response by Dave M on the 9th Oct 2016

Hi Neil
Brilliant models. Wish I could work in metal to that standard.
Dave

Response by mactin on the 9th Oct 2016

Hi Mark The motor duration depends upon gearing,prop size,submerged mass etc.. but i try to get about 2-3minutes its a balancing act between duration versus torque, but they all dynamic dive and surface when the motor runs down, with the 28"U30 that one can also static dive with its clockwork timed compressed air tank. you can set the timer for 5mins to 2hours then it will blow ballast and surface. glad you like them matey.
cheers neil

Response by mactin on the 9th Oct 2016

Hi Dave, honestly mate you can do it easily enough with a bit of messing around and practice,i dont use any presses or machines its all done by hand, get yourself some good sharp scissors,a scriber and a steel rule and some old tin cans. start by just getting flat sheets,practice with paper first and form your shapes, then do exactly the same with tin using your paper as a template. just have a play with it you,ll be surprised at what you can do.
cheers neil

Simply outstanding, you could make a small fortune selling them! Great looking model, She looks so ominous just sitting in the water.

Response by jarvo on the 9th Oct 2016

Fascinating to see your work, odds and sods we all through away, would make a fine magazine article for model boats.
Mark

Response by mactin on the 9th Oct 2016

hi Mark, I honestly wouldnt know how to go about doing an article but anyone has permission to use any of my site images and commentary. It amazes me just how much gear can be got from stuff people chuck away,im not a mad environmentalist or anything its just that its either dirt cheap or free! really glad you like my stuff.
thanks neil

Incredible models, I particularly like the U34. I would commission one of those just to sit in my desk it's so nice. Well done Rob, they really are superb, thanks for sharing. 👍
