  • There are what? About a dozen different plastic types Lego uses? There might be a batch of plastic that was used that is slowly shrinking over time from off-gassing. (Typical bricks are ABS which don’t have that particular problem.)

    There might be a defect that someone else is aware of, but you might need to replace the connectors or glue them. Heck, you just need to fix the friction fit so creative use of PTFE thread tape might work.

    (Not a Lego expert, but I do my research into plastics and such for other reasons. I want to guess that it might be the PMO (Delrin) that is causing the issue which is absolutely not approved for use in spacecraft.)

    Edit: Clarification on the PTFE thread tape use. For those who are unfamiliar with it, it’s not sticky and does not have any glue on it. If anything, it’s going to be a bit more slippery than other plastics. If you had two bricks and put a layer of PTFE tape between them, it’s would be thin enough to act as a wedge between the bricks to fix a friction fit but you should still be able to pull the bricks apart easily. You would need to experiment though.













  • Regardless of the side, if the convicts have proper training, supplies and aren’t used as pure cannon fodder I don’t have any issues with it personally.

    Honestly, I am surprised that Ukraine wasn’t doing it sooner. Unfortunately, the front has been somewhat slow for the last year or so (with an exception or two) and that means both sides are dug in fairly deep.

    If Ukraine decides to push back harder and start retaking large portions of land, their losses are going to skyrocket. Regardless is you agree or not, using convicts to push the lines makes sense and doesn’t risk better trained troops.

    That is just how wars of this type work and the offensive side will need to absorb more damage.

    Personally, if I had the option of fighting or rotting in prison, I would fight and would probably volunteer for some of the hardest work. The thing is, it would need to be my choice and I hope that any convicts, Russian or Ukrainian, get a choice in that.







  • you’ll be doing the QA and will in fact be working on the parts / product to get it to where you need it to be.

    Absolutely. Unless a person wants to spend thousands of dollars on push button solutions that cover every imaginable use case, customization is the way to go.

    For solid machines, the customer should already have an idea about what parts need to be modified. If a machine was advertised to mill a widget at +/-20% tolerance, cool. If you want to spend $500 more on a custom pully to get withing 5%, awesome. Precision is expensive and customization is niche.

    For cheap machines, everything is generally ravaged by bean counters at every level of design and manufacturing. As long as people understand this and can make repairs, that is sometimes OK.

    While I feel OPs pain of finding a 2¢ part that was 0.3mm off center, I can only just shrug it off. A pseudo-premium 5¢ part or building a jig for a worker to test each gear would have been quite expensive and it would probably tack on $2-$5 to the end product price. ($2-$5 actually matters on sites like Amazon or Temu and could potentially cost thousands in lost sales due to product placement.)
