I live on a sailboat in the Eastern Caribbean. I visit the USA every year usually in February to go skiing and plan to organize my purchases to be consolidated in Miami and transported down to Grenada by a commercial shipping line. I would like some help to make sure I am starting off with everything major I need to complete my first two projects. Why well there are no places to buy this sort of kit in the islands and the postie/UPS/Fedex have a hell of a job finding me as I wander up and down through the islands.

These are my projects

I STUART TWIN OSCILLATOR a twin cylinder 'wobbler' steam engine.

II The Whittaker Firefly 46 a single cylinder glowplug engine. Possibly a bridge too far but we shall see.

This is what I plan to buy to get started. Please tell me if I am making any NOOB mistakes or missing anything critical.

My shopping list.

7 x 12 mini lathe footprint is 27 ¾ x 8 ¾ Harbor Freight $450 with coupon. My work bench is only 30 inches long so this is the largest that will fit
4 jaw chuck plus studs and nuts to mount.
Drill Chuck, 1/2" with 2MT Short Arbor
Set of center drills I have a set of good drills
Milling Attachment Package, Mini Lathe
Dial Indicator and Magnetic Base
0-1 inch micrometer
Electronic Digital Caliper, 4"
Cutting fluid 2 types
11 PCS 5/16“ CARBIDE TIP TIPPED CUTTER TOOL BIT CUTTING SET METAL LATHE TOOLING OR [ maybe AND ?]


Grizzly H5871 - 8 pc. HSS 5/16" Mini Tool Set OR

Turning & Boring Tools, 5/16" Indexable, Triangle Inserts 5 pcs


I am not sure about the type of tool to buy as I know very little about tool sharpening and keep reading contradictory advice on tool types and sharpening. I will not be doing large amounts of work and would prefer not to have to make my tools from scratch HSS stock.

Baring in mind that space is at a premium and I would like to avoid having a bench grinder onboard can I get away with a small diamond wheel mounted in an arbor and spun in the chuck for sharpening. I know about using dust shields. Maybe there is a better option.

OK FOLLOWING SUGGESTIONS I HAVE ADDED

Lathe spares kit
Taps and dies the wobbler will most likely use that peculiarly British BA format so a set of those plus some small Metric taps for the Firefly.
Set of small files.
Small vice 3 inch Harbor Freight

What kind of boat ? I will def go along with you don't want a bench grinder , too messy but the time will come when you need one so I would look into a nice vacuum set up . So for sure go the insert way plus some taps and dies , some files and a good little bench vice . I know I'm leaving out some stuff .

I do have a separate 25 inch bench which will need a vice and just maybe a small drill press.
If you are open to a Drill press, then you might consider upgrading to a Mini Mill. You could also then drop the lathe milling attachment and put the $ towards a Mini Mill.
Grizzly, Little Machine Shop and HF all sell configurations of the Mini Mill.

I looked up the layout on your boat. Nice boat. Where are you planning on placing the lathe?
bombay_explorer_44_drawing.jpg

I lived aboard my Gulfstar 37 for 10 years with 7 years in Mexico. Dealing with leaks, condensation and the inevitable saltwater corrosion was a constant battle. What are your plans for dealing with saltwater corrosion? These small lathes are not made out of stainless steel or bronze and will rust/corrode quickly in a saltwater marine environment. Do you have a generator on board and is it big enough run the lathe? Does the generator put out a proper power wave so as to not damage the motor on the lathe? What are your plans to confine the chips and the lubricants/cutting fluids so that they don't migrate all over the boat? These are just issues that came to mind as I read through the thread. I am sure that there will be others that rear their ugly head as you progress with this project. Buying the lathe and tooling is the easy part of your project. Interrogating it into the boat will be the hard part. I look forward to following your progress.

I have a suggestion for a vice and it is a Z-vice. probably one of the most useful things to have on a boat. I've got two of the originals by Zyliss and now they are marketed by 'Renovator' on TV. These seem to be of the same high quality. With secondhand ones I have heard that some time after the Zyliss name was dropped the manufacture was farmed out East and they were N/G. 'Renovator' stuff all seems well made and they have an excellent guarantee. I can personally attest to just how good they are and for marine work they are the bees knees.
Here's a sale video for them:

I am a newbie but I would check out little machine shop it has same lathe with upgrades such as rpm meter it might even have the up graded bearings that many harbor fright guys have done on you tube they also have all the accessory you might need for it did you know the harbor freight has plastic gears LMS sells a complete set of metal ones do some research for comon itiems need for repairs for your lathe.. next for your situation I would go with high speed steel tooling being isolated like that getting insert might be a problem. As a newbie I started with inserts but found high speed steel worked better on my lathe pm1030 there is a learning curve but well worth it would buy precut tools and bunch of blanks to make some fore custom tooling. you will need a grinder but lms has on that attaches to lathe https://littlemachineshop.com/products/product_view.php?ProductID=2001&category= a good honing stone for keeping tools sharp. I would check out frank hoose https://www.youtube.com/channel/UC89zCBbbQ6L3yzu60NP-4Tw on youtube for mini lathe reviews and ideas and then keith appleton https://www.youtube.com/channel/UCgeQiJg-PIH5MZQn0aRd1mg for steam engine modling

I am going to take out the small toilet in the center of the boat. This gives me a 30 x 15 bench and a 10 x 25 bench with some locker space. This is my 15th year as a full time liveaboard so I am used to protecting stuff from rust. It is warm year round where I cruise and very high humidity days are rare. Liberal use of the oily rag and CRC spray should keep things moving. Dealing with chips esp the steel and cast iron will be difficult but I have a shop vac so we will see how it goes. I will have some carpet in the workshop which will be regarded as disposable every few months.

You have thrown a potential spanner in the works though as I was intending to run it off my Vector Maxx SST 1200 watt inverter which turns out to have a modified sine wave output. So I need to find out if it will do or will the magic smoke escape from the lathe speed controller the first time I use it.

My Honda generator has a pure sine wave so that should be fine JUST NOISY.

was it me, I would get some HSS bits instead of the carbide, and a very small grinder to grind them. Also, I would get a dial indicator caliper instead of the electronic one, it might be more resistant to corrosion, and will work without a battery. +1 on the best vise available, you can do an awful lot with files and stones if the work is held securely.

Grizzly's 7 x 14 G0765 listed a length of 29 3/4 inches. Those two inches may come in handy. Littlemachineshop's 7 x 16 hi torque blows your budget at 31 inches. I would think about some blank HSS tool bits and a small grinder, as you may need to grind some special bits to make some features you may need. On that note a stock of several sizes of drill rod and a torch hoss enough to heat them to red heat for making special tools and boring bars would be of interest. You may also want to get some silver solder to go with that torch as well, in case yo need to build up a part from several pieces (or fix an error). Loctite is good to have for that, too. A collet chuck (MT3 ER 32 or 40 with collets) may also be handy. You can't have too much tooling for the lathe. Unfortunately, no one makes a boring table for that lathe, which would be very nice to have. Check out some of the casting kits on Metal Lathe Accessories and the kits on Hemingway Kits in the UK, Hemingway specializes in tooling and kits for building small steam and gas engines. Take care.

My only advise is go as large as you can on the lathe and the mill. Separate machines are better then lathe adaptors to mill .

Thank you Silverbullet If I had the space I would indeed go large but I live on a boat and my bench is 30 1/2 inches long. x 15 plus a smaller space so a 7 x 12 with a milling attachment is about all I can fit in.

Leveling the lathe is not important as long as it is straight and square. I spent the majority of my working life as an engineer of cargo ships, all are fitted with a workshop usually at least a decent lathe often a mill and other machines these machines are never level, but great care is given to fixing them to a stiff rigid base and making sure they are square.

I'm assuming the mini lathe has a variable speed motor, the controller may not be happy running of the modified wave. Rather than have to run the generator you could replace that inverter with a pure sine wave one, they are not that expensive given the amount you are spending. I'm also assuming you have plenty of battery capacity.

Alternatively you might try running a motor alternator in the circuit that might just tidy the wave up sufficiently that your lathe speed controller won't mind.

Also rather than CRC I'd consider using INOX MX3 a far superior product than all the commercial CRC, WD40 etc etc.Also makes an excellent cutting fluid.
