https://fantastic-plastic.com/US MOON SHIP PAGE.htm"First released in 1958 as the "US Moon Ship," this model was subsequently re-released in the late 1960's as the "Mars Probe Landing Module," then again in the 1970's as the "Star Probe Space Shuttle." It was ultimately re-released by Glencoe Models in the 1990's as the more appropriately named "Lunar Lander"."
I wouldn't assume that, but I certainly wouldn't assume not. My brother-in-law is an ME who used to do a fair amoumt with springs (though not tortional ones like this) so I've asked him if he can offer any advice.I assume there is some standard spring nomenclature I can use to figure out a replacement.
Trust me, more a comment on the rower construction/quality than the power of the rower. Given how little I row, only when I can’t do any others exercise, it is really hard to justify more than the cost of the spring. Today I wanted to run as it was overcast and cool, but I did too many miles last week on shoes that are apparently end of life (only at 400 miles, but I’m not a light weight), and my lower back is not taking impact well today. I did get over to the Nike store, and pick up a sweet new pair of running shoes...now I really want to get out there.That's a badge of honor, you need a stronger rowing machine!
That type of spring is called a "clock spring". You *might* be able to find replacement metal (a narrow strip of spring steel) from somewhere like McMasterCarr. These things can hold a lot of energy!Snapped the spiral spring on my row machine responsible for cable retraction. How do I figure out a replacement? Customer service on this POS is going to be non existent. I assume there is some standard spring nomenclature I can use to figure out a replacement.

Possible fixes: (A) Overlap the snapped ends by an inch or so and re-attach with a couple of iron rivets. Aluminum pop rivets may not handle the wear/tension. Need a hard bit to drill spring steel. (B) Overlap the ends and silver-solder; better yet, scarf the ends to a taper before overlapping and soldering. (C) Take it to a machine shop and have them re-attach the ends with a bandsaw-blade welder.Snapped the spiral spring on my row machine responsible for cable retraction.

Good idea to trust Dad. If it doesn't work or breaks again, you still have the $80.00 option. Although one might have to consider if the rower is worth less than $80.00 used, maybe time to consider an upgrade? Hope a farm auction spring works out for you.Thanks for the suggestions folks. I’ve done some reading on the inter webs, and this spring is a known flaw/weak point in this model. unclear if there is a fundamental design issue, they are using jenky springs, or both. The company will only sell you the entire flywheel assembly for $200...hard no on that one. McMaster has a similar spring, but would be about $80 with shipping. My Dad is digging through his spare parts for a similar spring (he knows he bought a big box of springs at farm auction sometime ago for a couple dollars...the dude has everything in his shop). I’ll probably install the closest thing he can find, and go from there. That is about the $ and effort I want to put into this thing at this point.
That's why I have a sweet little Laney with DI output. I can play as loud as I want through my headphones and not wake up my whole apartment building.You might be wondering what good a 1W amp is. It's a good practice amp. It'll drive a single 12" speaker and it will overdrive without causing a knock on the door from the ladies and gentlemen of law enforcement because your neighbor bitc... exercised their right to a quiet neighborhood. .
Seems like I'm a little late, but here's what the brother-in-law has to say.I appreciate it, thanks.
Its a constant force spring. I haven't worked with them at all but gave run across the literature. Here a is a good link:
It almost looks like the whole assembly can be replaced pre-assembled. The mechanical reels look promising. If he knew the load and stroke of the spring he ought to be able to find a substitute: but I'd wager he'll need to replace them in pairs to keep the load balanced ( unless the machine does that another way).
That sounds like a fast track to hearing loss.I can play as loud as I want through my headphones...
Never said I wanted to play extremely loud, just as loud as I want. I live in an apartment and work nights... it’s nice to have headphones to play through at 4am instead of a cab turned down to barely perceivable levels. Thank you for the concern, though.That sounds like a fast track to hearing loss.
