follow up-
this thing glides through aluminum, but couldnt cut 4130. i modified the rake angles a couple times but it still didnt work, i dont think the tool steel was up the task. i ground a second parting tool out of a 3/8 blank clearly marked HSS, and it worked wonderfully on 4130.

going imperial

i always thought the english or imperial system of measurement was stupid. basically arbitrary origins that dont make sense in a logical sort of way. i mean, 64ths?! come on now, that is weird.

working as a wrench in bike shops for a long time did not help my distaste for imperial measurement. yes, there are a few of english sizes of things on bikes, tubing is english sized-- 1", 1-1/8", 1-1/4", some clamping designations...but in the shop we still convert them to our lovely metric 25.4, 31.8 and so on. but there is also a lot of bike specific dimensions that is metric. dropout spacing, BB widths, bolt circle diameters, seatpost sizes, and a whole bunch of other things.

metric is just easier to do mental math, i became comfortable with it.

but i had to make the switch back to imperial. why you may ask?
my lathe/mill, an emco v10p, is an imperial machine. this particular machine was manufactured in austria, and came available as a metric or imperial. obviously the majority of the the units imported to the US are imperial. an interesting thing about the emco is that bc it was built in europe, all of the fasteners and wrench sizes are metric.

all of the scaling on the lathe/mill is in thousandths. 0.001 of an inch. for me to become adept at using the machiney i had to become comfortable with fractional measurements and converting to decimal.

i feel a lot more american now that i am comfortably using inches again.

the hard parts are done.
with the rack at this point, the rest sorta falls together.
but dont get me wrong, there is still a fair amount of work to be accomplished.

approaching completion

3 holes for maximum adjustability. only need to use one hole per side. the strips were drilled simultaneously on the mill.

intersection of the support legs. laying down these little fillets is fun. i spend less time brazing than any other rack building operation.

new rubber

i have used many continental bicycle tires over the years, and been happy with them (for the most part).

so, i decided to try some contis for my automobile!

this may possibly be the ONLY true ALL-season tire, with attributes specifically tailored to driving in the snow.

besides working well in the snow (which we've had a couple opportunities to test them) , they do everything else much better than the last tires we had. much quieter, better handling characteristics, and better ride quality.

so, if you live in an area where the snow plow may or may not show up, the continental extreme contact DWS may be for you!

a quick note

having ones own mill/lathe at home is a beautiful thing.

pics coming soon.
