Besides FTEs, and I recently read Color Shifters, what are good sources for 'stock' NPAs? Does anybody consider #20 sewing pins to be a legitimate substitute?
Pretty sure #20's are about as close to a 'stock' axle as you can get. #17's work, too, but it allows the wheels to wobble just a tiny bit, and wobble kills speed.
If a race rules state stock or NPA's I believe they mean just the axles that come stock on any HW/MB cars, whether NPAs or not. Any other item used as an axle wouldn't be "stock," as is my understanding. Some allow tubes/custom axles, but most say stock/NPAs. Best to ask the race host.
I have heard of "Tubing", A while back when I first started researching customizing techniques. I haven't tried it yet. I wanted to build some regular test cars to learn from. I have some plastic tubes picked out. I have decided to allow "Tubing" in all of the races I am trying to bring to the table.
I wonder if a slightly bigger pin to the hole in the wheel could actually help solve the "egg" hole problem. I little bit of extra sanding/polishing..
We are trying to set rules for the drag strip at the slot shop, and want to throw this out therethere is the concept of rules that are hard to enforce/determine outcomeIf you said no pins/tubes, etc it would be hard to tell on some builds unless the car is taken apartI say this not to encourage cheating, more as to when setting rules a means of "inspection enforcement" should be consideredas an example:If I said; "no lube", determining if the wheels were lubed, then cleaned would be hard to figure out,puts the inspector in a bit of a judgement call situation, because the determination is not easy and obvious.so it's easier to not ban dry lube, but to just say no dirty tires/wheels (white paper test)
Check out this FTE FAQ to get some more details on FTEs and NPA axles.
Say I buy a Color Shifters off the pegs today. I've read that the wheels themselves can be junk so I just need the axle. The only way I know to get wheels off is to cut the axle and slide them off. At this point I'd need to brass tube a new axle together, using the wheels I want on the Color Shifters' axle halves. Is this a common method you veteran builders use to make faster axles while still staying compliant with the stock axle rules?
So #20 pins and brass are not an option in most cases. What are the most common sources on the pegs right now for NPAs? I presume Color Shifters are one, anything else? Ultra Hots from Target?
