Ok you are pretty much all set with what you have. Def. drill the bore, drill to get started then bore to get them as close as possible, drilling and trying to ream is pointless (personal opinion). If you have long enough boring bars I would just stick to those. Investing in a decent reamer is $$, stick to what you have for your 'prototype'. And dude accidentally getting within a 0.00xx" is really f*cking good.

Good to know, and at school the best I did on purpose was .0002". But then that sounds like bragging.

Anyway, I like presicion...

Machinist through and through.

Razz Is it an internal desire for control??

For lack of better wording...yes

It's how you know your work is right, if it's not start over. (I've Burnt through a lot of steel...and that was with cnc fiber/co2 lasers, plasma, and big f'n press brakes...my old boss hated me but everything that came from me was perfect). And now I'm bragging, oops

do you know which tool will take the least material when cutting through metal? just curious.

I am guessing a wire edm, but maybe a lazer?

I can't answer that confidently, my experience has been only with co2 and fiber lasers, they're more out there though, the new tech out there can surely remove less material. Never got to play with an edm, but I'd like too.

Other peeps here may have a better answer.

kerf loss in wire EDM is the thickness of the wire. Call it 0.010 inches best case. Maybe 0.020" kerf when considering other tolerances in the cut (alignment, wire moving around).

Pretty good then. I will go research...

Here is more info. Not the best quality image but a good view of what it's all about...

Ben just finished his fixture and is up and running. This is exciting and his work has improved the design significantly.

I’ve searched and searched, but got nothin.

Thoughts- pros and cons of mixed wheel on a hardtail? Thinking, 140-150mm 29er up front, and a 27.5” in the back, for the sake of this thought excitement.

Would you pick a mullet over a standard 29er hardtail or not?

We don't do mullets for performance. They are a band-aid.

Obviously, someone hasn't ridden Marin trails.
