Spools

Last night I went to work on the lathe making a set of swingarm spools, which engage with the bike stand to lift the back end for wheel removal etc. They can be purchased all over the internet for $20-50 but buying stuff is no fun when you can make it yourself.

For the first time I setup my Quick Change Tool Post with my new carbide indexable insert cutters. Holy did this ever make the job a thousand times easier. Took about half hour to mount all the tools and set the heights, but once that was done it's about 5 seconds to switch between tools.

For some reason I can't access several of the photos I uploaded last night. I can see them on the right but they aren't showing up in the Inspector. So there are a few steps missing..

The pictures are self explanatory, I basically just whittled the bar into a spool. With the new cutters I was able to rip off almost 2mm from the diameter in one pass, AND the surface finish was still better than my old HSS cutters (mostly because I've let them go dull). I had a hard time parting it off, as usual, so I sawed it off with a hack saw and finished the back side. I'll post pictures of that operation later (those are the ones not loading).

I think they came out pretty good. They might be on the big side? Some of the ones on the net look a lot smaller, I'll see what Sean says next time he sees the bike.

Thanks spools! Ideally if I wanted to protect the aluminum from corroding I would anodize the parts. Aluminum has a natural oxide layer that provides some protection as-is, and anodizing increases the thickness of this layer and therefore the corrosion resistance. If I was daily riding this bike in the winter to the park-n-ride on salted roads, and wanted my spools to stay mint, then even anodizing wouldn't save them but they'd look cool a bit longer than non-anodized spools (anodized aluminum can be dyed any color). The worse this bike will see is a bit of rain, so, not worried. Besides, if they are going to fall apart every 5 minutes then they won't have a chance to corrode : ) - q20v June 1st 2017
Nice work as always. Is there a way to apply a compound while on the lathe to preserve the finish from oxidizing? I like the reverse use of the hardware to hold it in the chuck. Also drawings arent stamp so I doubt it'll hold the bike for more than 5 minutes. - ripcurl May 30th 2017
