As far as I know there are no programs that will give you a 100% conversion without some manual touch up. I found it was easier to scan what you want insert the scan directly into CAD, scale it, and trace over the underlay. On bulkheads and frames etc you only have to trace half and mirror the other side. This way you can correct any errors in the original. Don -

Doug, Speeds and feeds for milling whether manual or CNC can be tricky. It depends on many factors material, bit size, spindle speed, feed rate and the bit type (carbide, HSS, number of flutes) whether drill, end mill etc. and chip clearance. Check out some speed and feed calculators online to give you some ideas. The the short answer for the slower rpm is you can use HSS bits to cut hard material such as stainless or tool steel. If you switch to a carbide bit you can increase your spindle speed and feed rate without burning up the bit and get a good finish. In our h

Doug, EMC2 and Linux are open source software, you should be able to upgrade to a newer version without any cost. I am not real familiar with either thou but I am sure an Internet search would give you all the info needed. I use mach3 for my control software which is windows based and very popular with hobby and small shops. The important thing about both programs is they are based on old hardware platforms specifically the 25 pin parallel port. An old computer with the parallel port on board is an advantage. If you use a newer computer with no parallel port you will need to co

Recommendations For A Good Milling Machine
Don replied to Thistle17's topic in Modeling tools and Workshop Equipment
Joe Generally what they mean by CNC ready is that the machines are ready to attach the stepper motors. In short the brackets are attached to the machine and you need the stepper motors mounted to be able to use the machine in any mode. The handles attach to the shaft on the back of the stepper, then you would be able to rotate the shaft as if in manual mode. To run in CNC mode you need to attach the steppers to drivers then this controller box is attached to a computer with the controller software (the most common is probably Mach3). This is how almost all hobby CNC mills are -

Recommendations For A Good Milling Machine
Don replied to Thistle17's topic in Modeling tools and Workshop Equipment
I have a Taig CNC mill, the CNC machines have a bigger motor than the manual mill and also can run up to 10000 RPM. I believe you can have them put the larger motor on the manual machine. The Taig mills are a little bigger and heavier than the Sherline. The most common accessories like tilt table and the rotary table can be adapted for use on the Taig. I have the Sherline rotary CNC table and use it with the Taig. There are some differences in the manual and CNC versions of the Taig mill so look carefully if you compare the two. I agree with Jim on the 3 flute end mill. My -

Jud Yes with a little tweaking of the drawings I could probably come up with a Baltimore class hull. The Baltimore’s were only about 40 feet shorter and 6 foot narrower than the Des Moines class. The hull shape though is almost identical. If you sat the 2 different model hulls next to one another about the only difference would be the length. Bob and Nils Yes that is a custom built table just for this model. The risers under the hull are milled for certain spots along the sheer line and screwed to the deck. Then I screwed the risers to the table which resulted in the keel bei

David Most if not all of the hardware and fittings will be scratch built, a few exceptions my be some photo etched stuff from The Floating Drydock. The problem with this particular ship is that there was only three in the class; the Des Moines, Salem, and the Newport News. The Des Moines and the Salem were use as flagships for the Sixth Fleet and the Newport News was used as a flagship for the Second Fleet. The Newport News heavily modified and served into the Vietnam War, the Des Moines and the Salem were decommissioned around 1960 or so. It is much easier to find good plans and information

Thanks all for the likes Hopefully by starting this log it will keep me on track and moving along. This one project I want to keep moving and not drag on any longer than necessary. One my dad isn't getting any younger and two I want to get this beast out of my shop. I don't mind working on larger models but this one at times is a bit much. As I get the hull more complete I will be able to work on smaller sections at a time. This will help by having less moving around just to get one row of planks from the bow to the stern. Once I get it flipped over and start working on the superst

Dust collection and extraction
Don replied to Trussben's topic in Modeling tools and Workshop Equipment
Hi Ben I have a 24x26 shop for woodworking and have basically the same equipment you do. I am on my second dust collector which is a 1.5 HP single stage, this works fine for what I use it for. I don't do as much woodworking as I used to so this works just fine. If I get another one I would probably go with a smaller cyclone type collector they are more efficient and easier to empty, especially if you do a lot of planing which creates lots of chips. For my modeling area which is in the house I use a Fein dust extractor which I just love. It is quiet and variable speed but more expen -
The USS Des Moines class heavy cruiser was the largest heavy cruiser ever built. It is similar to the Baltimore class except bigger and only 1 stack. The main difference is the Des Moines class has automatic 8” guns using an encased powder. These guns did not use bagged powder that was normally used in guns this large. The guns were capable of about 12 rounds per minute per barrel compared to the Baltimore class at about 6 rounds per minute. I am building this model for my dad which served on this ship from 1958-59 and has always wanted a model. I am finally getting enough time to g
