Laser Project

Should imagine buildings are better - its difficult to find slab sided objects to make. Curves are a problem as other than my boats we use 3 & 6mm MDF, perspex, and various types of 22mm good timber to make our sales bits. Liteply, Balsa & Birch Ply etc is reserved for the boats as its relatively expensive. Make some labels out of Rowmark which is very useful - usually gold or silver with black engraving. Our real problem is marketing for the toys etc - not much demand for it here - could send you a couple of designs on dxf files for 3mm MDF if you wanted for a bit of fun including the Siege Catapult.

Im a couple of years younger - also have a good eye - cant stand rivet counters and what really gets my goat is "True Scale Colours" - which are definitely not as they fail to allow for scale distance...............

We clearly both achieve the same thing re the kerf using different approaches. For instance when inserting a window for a boat I always scale up from the cutout to give a precise fit.

My laser is also a Generic Chinese Red and Black, 80 watt with a 750 x 500 bed. I rarely cut anything larger than 450 x 300 purely for convenience. I purchased it as a hobby machine and that's all I currently do with it. I actually use the kerf (cutting thickness) to my advantage and make no adjustments to compensate. If I'm cutting a slot in 1.5mm ply for example, I'll make the depth 1.6mm so that the two parts will sit neatly. The glue takes up space, and the .1mm seems to be good enough. Gluing the remainder of the slot is fine because the kerf allows space for the glue.

I'm not a rivet counter, but I do have a good eye at age 79. If it looks good to me, it will probably look good to most people. I don't worry about the few who may wish to criticise. My machine isn't entirely accurate, but any imperfections add character to the job in my opinion.

I spend a lot of time on the plans making sure everything will fit. I'm sure you will have done the same on your projects. I keep the machine clean, but otherwise it worked out of the box. I mainly make buildings which don't suit this site, but I've also built an HO ship and Gantry which I'll post tomorrow if I get time.

Nice work there - especially at N scale - what laser are you using ?

Always have a problem with the very fine stuff - the cutline on ours is approx .3mm thick so you have to add on for it to get the right width of components. Usually find between 100.5% and 101% does the trick. Ours is the Generic Chinese version with honeycomb vertically movable bed - nominal 600x900 - used for commercial stuff like Plaques , trophies etc. Lucky enough to be able to use it for my boats and for some Aircraft, Vehicles at 1/18th scale, plus the occasional Toy like a siege catapult all of which we used to market. Most are my design as well. Funnily enough sold the designs of a Land Rover Series 1 and a generic Jeep to a friend who has moved to Perth & bought a laser like ours there. Sent him a lot of others too - including a trailer, off road camper trailer and the Tiger Moth.

Fantastic work in such small detail.

If it looks right it probably is.

Hi Johnk,

Welcome back!
Your model looks very good!
I really like the details!
And the gantry looks awesome!

If that were a kit!
I would definitely purchase one!

Cheers, Ed

Hi everyone,

I haven't posted for a long time, so I thought I'd kick off with an N Scale (2mm foot) waterline model of a Container Ship and Container Gantry I recently built for my model railway club.

Everything you can see is laser cut. I have my own machine and I also designed the lot. The model still lacks some finer details such as a free-fall life boat and rafts. The model is just over 2 ft long (600mm). Materials are 1.5mm Ply (shell) and .7mm Ply for the skin. The gantry raises, but is otherwise a static model.

I'm sorry but plans aren't available. I'm thinking of creating a kit both in N and HO scale. It will depend on availability of materials.
