The Power of Smallᵀᴹ

I thought I’d add I have a lot of rectangular plastic stock. In fact I need more round stock and to purchase it is expensive. So I do like woodworkers take square pieces of stock and turn them round for stock.

When I was working in the machine shop of the company that employed me we turned a LOT of plastic. Big plastic bearings. I'm talking 9" OD x 8" ID x 18' long.

If the shop that you worked for still exists, they should try our products, all of our blocks and rods are low stress, machine grade.

The material we made bearings out of for the marine industry was made by Thordon. I was under the impression it was a specialty plastic developed just for marine purposes.

You can now make and sell finished goods from recycled plastic for less than the cost of new plastic resin! Plastic is an amazing material. It is used in all aspects of our daily lives. It's both a blessing and a curse.

Machining is machining, in aluminum, steel, plastics or wood. It is still machining.

I often prototype something in wood or plastic to get the kinks out before doing it in metal for the final. It is a great way to save time and money, and easy to fix problems.

I recall when I spent two 8-hour turns making some shifting forks, and when I got to the final operations I realised that I had made them in a mirror image of the actually required part.

I headed for the bandsaw and cut one out of a scrap 2x4 and put it near the Cincinnati's vise so I could make the next two forks correctly.

Prototyping out of plastics or wood is hard to beat.

Whenever a left, right, or mirror image part is required remember... Bob's Law.
If there is a 50-50% chance of it being correct it will be wrong 75% of the time...........Bob

While we are on the subject of, "made here".
I've been working for Ford dealerships since 1976.
The dealership I started at had parts manuals back to the 20's. For decades you could repair parts and components. Remember the old cam driven diaphram fuel pumps?
Heck, you could buy the diaphram, gasket, spring etc. Starters, generators could all be rebuilt. We would grind valves and replace bearings, hone cylinders, brake cylinders would be rebuilt. Unheard of today. It wasn't until 80's that we migrated into assemblies.
Now days, we don't rebuild a transmission, it would be cost prohibitive. We sell a factory remanufactured unit that carries a 3 year unlimited parts and labor warranty. If we rebuilt it, you would get 90 day labor and 24 months on defective parts.
The business has changed!

I hear that about change! But like engine and trans rebuilding you mention " cost prohibitive ". I've seen firsthand the rebuilders are cutting corners and 99% of rebuilds don't last as long as OEM, but just long enough to get by the warranty. And I for one miss being able to rebuild my cars but cannot think of a single plastic thing that could rebuilt.

Good point C-Bag. Before my 2002 F-150 burned in the fire, it had the original transmission, the engine did not burn a drop of oil. It had 257,000 miles on the old 5.4 l engine.

I remember when one of the local Ford dealers lied to me about how "Ford doesn't sell the fan motor separate from the fan assembly, which is $ 650."

Two hours later, with only $ 71.00 duked to the auto parts store, the replacement fan motor was operational in my 1991 Taurus.
