Nice work ,me and paint don't get along ,the less painting i do the better off the model is lol

I'm going to follow along, I love stuff like this 
 

Shadow and white spots added

Perhaps a router speed control similar to this might work for you. It was $20US. I use it also to control the heat from a 1Kw electric blanket for bending hardwood. 
 
Another alternative would be to scavenge the DC motor and control board from an exercise treadmill (often disguised as clothes racks).  They're usually rated ~2HP and spin from ~50-5000 RPM.  The flywheel-pulley is a common poly-V belt with ~8 grooves.  I'm using such a motor on my 10x36 Midi woodlathe, and it's plenty enough power.

It also creates a flat top so the entire model can be flipped to help with planking and fairing.   Something I noticed was a real pain when other folks were making their cross sections.

Today I finished The base and mounted my cross section. This was a real fun build, and I learned so much from building it. Thanks to the members that followed along with my build and gave me words of wisdom , encouragement and kindness.

Two weeks ago I went to the local machinery suppliers open day and came away with a nice little X Y table. It came out of the redundant stock bucket and was a snip at £30. 

 
It is made of cast iron / steel (unlike many cheap fleabay products) and has gibs and locks on both axis. The hand wheels are calibrated in thousandths of an inch with one revolution giving .050 inch travel (20 TPI). The x travel is 5.250 inch and the y travel is 2.625 inch.
 
I had been thinking about making a mini mill for a while. I find my bench mill is a bit too meaty for the smaller ship work and its maximum speed of 2400 rpm is much too slow for smaller drills and end mill cutters when working on aluminium, brass and hardwood. 
 
I did a bit of calculation on cutters of up to 3mm diameter (table below) and concluded that a spindle speed of 10,000 - 30,000 rpm wouldn't be too excessive.
 

Having bought the table I had a hunt through my "rainy day" store and came up with the following:-
 
Cross slide lead screw from my long retired Boxford lathe. This is nicely engineered with the screw mounted on double trust bearings and calibrated in tousandths (1 revolution = .100 inch). It will give me 6" Z axis travel.
 

2 speed "Rotozip" 550 Watt spiral saw body with speeds of 25000 and 33000 RPM. I have had this for 20 years during which time its had about one hours use. Its got loads of torque and nicely tight bearings. Ideally i would like to put speed control on it but as yet I'm not sure how.

A digital read out, bought cheaply on a whim for £5. ( I will need 2 more). Its Ideally sized for the x axis.


To make this a success I need to pay a lot of attention to the accuracy of the build but the first job was to come up with a design. I worked through a few options before coming up with the following general arrangement (drawn at full size).

 
The column frame will be made out of .375" thick aluminium plate and the milling head will run on two pairs of linear roller bearings riding on on a pair of .473" bars that in a previous life were kitchen door handles. 

 
This should keep me off boat building for a while!

Now comes the most difficult part, the decorations. I am not an experienced painter. Painting the molding on a flat paper is not so difficult, but reproducing it on the model which has obstacles as fenders and ladder steps is a whole other story. With blood, sweat and tears and of course with yellow paint I can produce something that looks a bit like ornamental garlands. It still has to be finished with white light spots and darker yellow shadows.
On the second picture you can see that the gaps between the planks were not yet filled when I was painting the moldings.

Thanks  Guys
 G.L. I haven't thought about my next build i was so focused on this one lol. I am going to try my hand at a ship in a bottle but will be looking for another  build to start as well .

Congratulation for finishing this beatyful section model

Congratulations, Derek.
That was a smooth build. Your cross section looks very neat. Well done!
I enjoyed very much your companionship in this group project. Disregarding some dormant projects, I believe that I am now the only active builder left on the Triton cross section forum (gives me a somewhat lonely feeling).
Do you have already an idea for a following build?
 
G.L.

Congratulations on the build. It looks great.
