Lower rolling resistance for tin trains

If you like long trains, you want them to roll as easily as possible. Lionel figured out a bunch of secrets to lower rolling resistance in the 1970s. If you like tin like me, Lionel’s needlepoint axles and Delrin trucks won’t help you. But there are things that can. Here’s how I get lower rolling resistance for tin trains.

Are VHS tapes worth collecting?

Are VHS tapes worth collecting?

If you’re looking for a nostalgic hobby that won’t cost a fortune, VHS tapes are very underrated. Although not as cheap as they once were, VHS tapes haven’t exploded in value the way other 1980s technologies have. Are VHS tapes worth collecting? I think they have a lot of potential.

VHS tapes have not increased in value to the extent that video games and computers from the same era have. The days of buying the titles you remember as a kid for pocket change may be past us, but you can still buy the majority of the movies you remember for a few dollars.

Shop vac blowing dust out back? It’s the filter.

Shop vac blowing dust out back? It’s the filter.

Is your shop vac blowing dust out the back? Mine always does after a while. Fortunately it’s an easy fix, and you don’t need to replace the unit. If yours just started doing it, stop what you’re doing right away and give the unit a checkup. You may save yourself 20 bucks.

A shop vac or similar wet/dry vacuum blowing dust out the back is always a filter problem: either your filter is clogged, missing, loose, or the dust is too fine. But once you clean or replace the filter, the problem goes away.

Commodore VIC-20 models

The VIC-20 was on the market for about four years, but that was long enough for Commodore to revise it several times in pursuit of lower costs. Here’s a look at the various Commodore VIC-20 models.

The VIC-20 was quickly overshadowed by the Commodore 64, but if anything, that means the VIC-20 provides a more affordable challenge for collectors than its more common sibling. Despite its shorter time on the market, the VIC-20 has numerous variations for collectors to pursue.

How long does a mechanical keyboard last?

Mechanical keyboards are expensive, so it’s understandable to hesitate to spend half a day’s pay on a keyboard not knowing whether it will break. So how long does a mechanical keyboard last?

Mechanical keyboard lifespans are rated in millions of keystrokes, which sounds impressive but is hard to comprehend. Practically speaking, a mechanical keyboard can last decades.

Silver frame Marx cars

Silver frame Marx cars

In 1938 and possibly 1939, Marx produced its 6-inch cars with plain tin-plated frames, rather than lithographing or painting them. But these silver frame Marx cars were short lived. As such they provide a challenge for collectors today.

Silver frame Marx cars are a bit difficult to find because of their short production time but are also easy to fake. Don’t pay a heavy premium for a frame that looks too good. In this blog post, I’ll tell you how to identify one that’s too good and probably fake.

Why are mechanical keyboards so expensive?

Why are mechanical keyboards so expensive?

I’m a mechanical keyboard fan. Mechanical keyboards have gone in and out of fashion, but I kept using them regardless. I only see one drawback with them: the cost. So what does a mechanical keyboard cost? And why are mechanical keyboards so expensive?

A mechanical keyboard costs 10 or even 20 times as much as a cheap membrane keyboard, so the price can be off-putting. The reason is because mechanical keyboards have many more parts, and they are more labor intensive to make. The cost is easier to justify if you use it a lot, but the price does make it feel like a commitment.

Will a table saw cut through nails?

Will a table saw cut through nails?

Will a table saw cut through nails? Unfortunately I know the answer is yes. But I don’t recommend it, generally speaking, for a couple of reasons. 

The visible sparks that happen when you try to cut through nails with a table saw suggest what you’re doing isn’t a great idea. But you’ll also dull your blade, which creates a safety hazard long after the sparks stop flying. Read more

How to fix a crooked valve stem on a bike

My son asked me to help him air up his tires on his bicycle because the valve stem was crooked. His friends tried to help him and couldn’t figure it out, and it was a new one to me too. Here’s how we learned to fix a crooked valve stem on a bike.

The good news is you don’t need a new bike or even a new tire, necessarily. Crooked valve stems are caused by a deflated inner tube bunching up. Sometimes you can deflate the tire and straighten the stem, but other times you have to pull the tire and stretch out the tube.

Why VHS beat Betamax

Why VHS beat Betamax

It probably wasn’t the first format war and it certainly wasn’t the last. But VHS vs Beta, the battle of VCR formats, has served as a cautionary tale for more than a generation now. But there was no single reason why VHS beat Betamax. It was an accumulation of things that led to VHS winning.

Betamax was first on the market, and it had better image quality and generally better build quality. But VHS cost less and the tapes gave a longer run time, so in the end VHS won because it achieved critical mass among early adopters first.
