Title: Big Lathe?
Post by: mr.mindless on August 01, 2014, 12:43:13 PM
Does anyone have a lathe that will pass 2.5" stock to consider making our own 7075 suspension links with? Since Matt has the right taps, I figure it's worth pricing material and comparing to the finished product, if someone we know can actually thread them...

would a brake lathe work?
Title: Re: Big Lathe?
Post by: mr.mindless on August 01, 2014, 01:28:44 PM
I've never actually seen a brake lathe - but I wouldn't expect they have auto feed for tapping or drilling operation, they're pretty much just set up for honing and trueing aren't they?

40" of 7075 @2.5" is 20lbs

40" of 2x2x.250 steel is 18lbs

wow. I redid your math and their math because I didn't believe it.

on the alu you remove a bit threading it and you're done, and on the steel you weld a bunch of additional to it, so probably nearly same finished weights.

2.25*40 Al = 16.22#
2*40 Al = 12.87#

steel math:
40*(2^2 - 1.5^2)*.2904 = 26#

bah!

Title: Re: Big Lathe?
Post by: mr.mindless on August 07, 2014, 11:55:31 AM
I may be rolling through that way on Sunday with my goose. Could set it right on the crossbeams IF it is a solid base unit.
Title: Re: Big Lathe?
Post by: M4wdFab on August 07, 2014, 11:59:04 AM
if its 3" pass through, ill store it.  make links.  scrap it after or keep lol

says it has 3 chucks, and two of them are HUGE


motor and pulley system is above the chuck, it appears to be 6-7' tall, 10' over all length. 


I guess it would need two cherry pickers, a welder and some box steel to winch it to a flat bed.

or pay a roll back to deliver it would be way easier

Apparently, yes. Why? Wish I knew.

I blame outlooks defaulting to reply above original and discouraging trimming quoting and line by line reply. It fucked people's mindset on replies.

We got her.  Door to lot about 6it hours.  That was a pain.

Super high cg on this thing.  Probably 600lbssome in tooling.  Felt heavier than a 4.0/ax5/231 on the drive side. 

Gona need some maintance but looks like a good old girl.


Used every beam, plank, pipe, tool, strap and 2 of the 3base pickers we brought.

I don't think I'll hurt for this tmw, but fuck that was a lot of work.

Couldn't have done it without Jeff. We almost called for you to bring beer around 11:00.
