the age old bullseye problem isn't a problem when you can make the spacer sleeve the right length, it actually works really nice when it's done right. it's way less work to just do it like this. all the threaded collars are for a 3/8 axle and these are 12mm, so i would have to make collars too...... i'm trying to think what size that outer thread would have to be, i guess m12x1.5 would be the choice. you would have .1" between the major of the 5/16 and the minor of the m12 so it would work nicely. but thats not a path i want to go down

Re: Latest machining project

Yeah, but you can make anything.  Personally I believe those little grub screws slip a little and create more problem.

yeah they don't do anything... actually they do something. if you didnt have them you would have to make the collars a light press or transition fit otherwise they would just fall off and seem cheesy. so they make them easier to manufacture, one less tight tolerance to hold

Re: Latest machining project

i have made axles like this before. i have tnt hubs that are both locking collar and female, problem with that is you can only use 14-20 or m6 screw and thats a little small as far as holding power. because they are r6 bearings. i have seen mxr hubs like that also

Is that because of the freewheel width on the opposite side???

its because bullseye hubs are narrow. most hubs with the locking collars are either flip flop or i suppose just made wider. with the width of the non drive rear collar you could put about 3 pinch bolts on that sucker it would be locked up!!! lol it's no reason that you couldn't do it

Re: Latest machining project

I see... Good idea anyhow... I guess it might not be practical, but it is a good idea...

i just found them by googling japanese bearing, i have gotten a lot of kind of cheesy bearings online and it seems to be hard to track down good ones. Maybe because i dont know what terms to search. But throwing the word japanese in the search seems to work pretty well.

Re: Latest machining project

BTW, SS knows his shizzle on the cnc game.  Awesome stuff my man!  And Nachi bearings are among the highest quality Japanese bearings being made today for BMX application purposes.  Be aware that that precision and price are directly proportional when it comes to Nachi...they ain't cheap.  But a cheap set of bearings will ruin the smooth finess of even the nicest looking parts!  Seriously.  It's like putting cheap oil and 87 octane in a high performance engine; performance goes from flat to funky and then to flatline.  Also be sure of what the numbers, letters and specifications mean when trying to find a source for replacement bearings AND buy a decent micrometer instead of using the gradeschool household ruler for gods sake!  Lol!!!

Re: Latest machining project

Thinking it might be nice to round the corners of the hex to match the diameter of the cups, i dont think there is much there but it might be a nice touch
