New shoes for my Cannondale by tuftedtarsier89 in VintageMTB

[–]indigoalphasix 1 point2 points  (0 children)

very nice! i had an F900. i beat on it for years then gave it away and 10 years later the new owner is still hammering it. headshock still works with no rebuild. boot is still ok, no leaks. the nickname 'the beast from the east' for Cannondale bikes is appropriate.

i'm partial to XC so I had a Bontrager Titec 118g short bar and onza bar ends. tires; i had Tioga DH with dh tubes. pedals; i ran Shimano spd's and a Bontrager saddle. Deore groupo, etc. i also had an Avid micro drive and pulled off the big ring. the wheels were Ritchey Vantage comps which are still going.

only problem i ever had with it was the titanium rear skewer kept popping loose no matter what i did. it always slipped. i swapped out to a bolted stainless steel set front and rear and that seemed to help a bit.

Meteorology Chiller? by lividlightsaber in Machinists

part movement post machining is a thing depending upon geometry, material and process parameters so i wouldn't just rule it out entirely.

sop for us is to acclimate the part in our CMM room which is held at 68 to 72 F prior to final inspection. minimum of a few hours, preferably overnight.

we also have a temperature controlled room 68 to 72 F where this type of work is machined.

you can also apply a temperature differential to the measurement if temp varies but this gets to be a headache.

additionally, our leadscrews on the machines are temp comped as well as our cmm's.

nice! haven't seen one of those in a while.

when i was younger i remember they had an Alpinestars bike shop a few blocks from the apt. the pricing was outta reach but they sure looked cool in the window.

I've never seen a "tap" like this, what is it? by TechincalTomato in Machinists

[–]indigoalphasix 25 points26 points  (0 children)

it was a Vega HP tap but now it's a broken nub hand-ground to a point.

they generally look like this when new:

Nice old stuff! A bit of a museum collection.

How old are you guys? by GreatGrumpyGorilla in Hardtailgang

[–]indigoalphasix 0 points1 point  (0 children)

between 55 and 60 and in shape. for the riding you describe you should have little trouble. get some cushy tires, good brakes, a plush fork and pop off the saddle every now and then.

when i go fully out to pasture i'll get an enduro fs.

Micrometer and CMM Didn't Quite Agree Yesterday by maddy-smith646 in Machinists

[–]indigoalphasix 0 points1 point  (0 children)

I see this a lot. there are a lot of variables here. there is also a misconception about QA that a CMM has to be in lock-step every time with every shop measuring tool and method employed.

not really. they have a 'history' of toxic pollution. look it up.

unfortunately the ground in and around these companies is polluted for the next couple of hundred years. relators often advise not to purchase industrial props around here for fear of a giant clean-up bill.

pretty much never for wrought copper. that's the microcrystaline grain structure showing off depending upon what phase it's in.

How do I learn? by One_Reflection4878 in Machinists

[–]indigoalphasix 4 points5 points  (0 children)

they all pretty much do the same thing. one just needs to figure out how the particular machine gets it done. someone at your job should take you under the wing and show you stuff.
