Re: 100+ Years ago

Amazing video! Imagine if a workman made a mistake after so much work had been done. The projectiles had to be spot-on. Any deviation from spec could mean the gun might not fire rendering it useless in the field.

Re: Wood Shaper Cleaning Up Steel Block

We have a product here called "Evapo-Rust". If it is available in the UK, it is a great product. Other than that, coco cola will remove light surface rust; just keep the cutters and block submerged in the liquid. Coco cola contains phosphoric acid which removes rust and grease. Works in taking oil s...

Re: Making a milling machine riser

Spro's recommendation would also be my recommendation; cut the head of the bolts off and replace them with studs and hex nuts.

Re: Book about precision

When I was about 12 (1946), I had a Delta drill press, a small chemical lab, an electronics bench. I would spend my weekly allowance on tools. I would go to Patterson Brothers hardware, downtown New York City on a Saturday morning and spend a few hours there before deciding what tool I could buy wit...

Re: Book about precision

I must be some sort of a nut. Other people read romance stories, crime stories, murder mysteries, comic books and even newspapers; me, I enjoy reading technical publications, ever since I was a kid, I would read tool catalogs when other kids were reading comic books. I wonder what a psychologist wou...

Re: Book about precision

Thanks for the great links. Although it is not the book of my original topic, I found this to be extremely interesting. I spent 3 hours reading one of the links. Many of the tests used on machine tools are still used today, but there were described a lot of other tools used to test machine tools tha...

Re: Milling procedure confirmation

I believe there are inserts available for face mills that are HSS to replace carbide inserts.

Backing up computer files

This is a warning to save all your computer data periodically on an external hard drive, CD or flash drive. I do all my train drawings using Autocad. I had a lot of drawings I made over the years stored on my XP computer. I didn't have it backed up and now my computer crashed. The computer service t...

Re: machining should square

First I would check that the hole in the grinding wheel is concentric. If it is, check with a different wheel. If wobble still occurs, I would "mickey mouse" a setup to turn the arbor, using the motor itself as the lathe. Taking the grinder apart and turning the armature/arbor on a lathe, isn't a bi...

Re: essential tools for milling

You really don't a full set of R8 collets. I would suggest 1/4", 3/8" 1/2" and 3/4" as end mills come in those sizes. You can get a drill chuck with an R8 shank, but if you have a drill chuck on your lathe that has a morse taper, you can get an R8 collet for a morse taper and you will not have to bu...

Ron: I'd like to see some photos of the B1 and DD1. -Dick Both locomotives are at an 80% completion as I shelved them in order to work on the GG-1. I lost any photographs I had of them when my hard drive crashed and the computer tech told me it couldn't be recovered. I will take new photos and try ...

Re: Engineers really know their stuff

This has been an interesting discussion as I revisit it. Back in the 50's I was a draftsman designing ships for the U.S.Navy. At that time, following WW II, ships were designed "overkill". That meant ships were built using tried and true methods developed over years of maritime history. At the time,...
