Sorry for lack of contact.

My mom has been a hospice situation...in another state.

Being there for her & here for work & the house payment...tricky, recently..

Appreciate the comments.

I'll be back.

[Twokidsnosleep]

No worries, best wishes to you and your family...they come first

[b-body fan]

Sorry to hear about your mom. Best to you and yours.

Wow this work is awesome

[vintagercr]

Wow this work is awesome

I agree!

As Y'all know, for quite some time, I've been saving my lunch money for a small benchtop milling machine.

Well, I've got my dollars together & am ready to buy.

Building a little cubbyhole area to set it up in & to do my builds...get them out of the clutter & busyness of the git shop.
Going to do some shelves on the back walls this weekend.



Drier/ regulator for my air system.

Oh this is exciting, can't wait to see what you come up with

Always good to se others buying tool I am drooling after. that left hand side would fit a nice little metal lathe as well....just saying

[Ognib]

It is exciting!

Seems like I've been saving for this forever.

Kind of an odd shaped little arrangement...kids are gone & the wife & I are in 900 sq ft.

I've got a small music room where I jam with some friends plus the git shop...This is my last available corner...lol...I'm out of floor space...the rest of the house is her domain.

Hi Ray!

Man I'm happy about reading this news.  I like the way your thinking goes about progression, and the execution.   Save, then play.  A really satisfying way to go .

Looks like you have a good and solid corner built up, and the controls are at hand.  Good stuff.

Good luck with your further endeavors, I'm in.

Take care and good you're back to your new bench.

Glad to see you back!

[Ognib]

Thanks for stopping in, everyone!

Appreciate the comments.

Can start moving some stuff in here now.
After I get the machine in place, I'll go ahead & shelf around it down the left wall as well.



Hung a drawer from an old rack mount system for tooling, bits etc for the machine.



I've been devouring the two milling books for a couple of months now.
Written by an old timer from way before CNC...talks about turning the cranks by hand...they assume no prior machining experience & spend time addressing which accessories are needed & which can be postponed for later.
Well written & very informative for a machine shop noob like me.

The rat rod book was a bday gift from my son, this year.
Not a real big fan of the genre but there are some good ideas incorporated in several of them.

Moving in!

Roadster stuff.

Body buck with practice panel & body shape templates.



Flathead headers.



Cowl buck & practice panels with front axle.

That is a cool space

Now you will be happy when she says "go to your corner!"

[Ognib]

Indeed!

Back when I was shopping for the rotary table & chuck, the 3 jaw models I looked at were all self centering.
I chose a 4 jaw with independently adjustable jaws...just so I could hold odd shaped pieces for rotary milling.
Had to "flip" two of the jaws for greater outside reach on the center section.

[Ognib]

 

 

I could see a #1 or 2 being used to bolt the side covers to the center section.

[Ognib]

The plan is that the machine will be on the bench, first week in June.

Been visualizing the process & sequences of building the rear end for this car.

There will be an output shaft with a u-joint yoke.
This will pass through a bearing collar & seal, which will be bolted to the face of the side cover.

My current research is dimensions for the yoke/shaft.
Collar can then be built to fit it's dimensions.
Mounting flange will build off of this.

Only at that point, will I really know what size I need to machine the side cover face so it will properly take the the hub & show proper proportions & perspective.

So, in spite of my excitement to see the center housing take shape, my first pieces need to be the shafts.

[Ognib]

The milling machine is on the truck.

It will be here Tues!

A shipment of accessories sent by UPS has arrived.
It contained some step block clamps, T slot nuts & a selection of R-8 collets in sizes to match tooling shank sizes that I already have.

[Ognib]

I fabbed this prototype collar out of short pieces of rod & tubing along with a washer & some super glue last nite.
Prototyping enhances my visualization/design process by allowing me to see the concept in 3D.
Visual proportion, balance & symmetry are very important to me in this!

The axle stub will have a flange to hold the rotor for the inboard brakes.
Scratching my brain over how to configure the mount for the caliper.

Also need to consider how the rear end will fit into the frame & design mounting points for this as well.

This is a very worthy challenge!!...& I'm diggin it

[Ognib]

[Twokidsnosleep]

Oohhhhh, that's pUUURdy

[Ognib]

Thanks for looking.

Since I'm going to start with these two pieces, the first setup will be the rotary table.



Front bolt hole is under the table & is accessed with it in a tilted position.
Had to rotate it 90 deg, as this way had the crank wheel on my left & I'm a righty.



I'm a noob at this mill work stuff...any of you guys reading this with experience at it...would welcome your critique of my setups & proceedures...want to learn the most effective ways to do this.

As always, I'm an honest reporter...I'll show my mistakes as well as the successes.

After squaring the rotary table & bolting it down to the machine, I set up the dial indicator for centering the 4 jaw chuck on the table.

Just eyeballin it in place, first rotation was .018 or so out.
After scooting it around a bit & some gentle taps with a nylon hammer, it's reading .0025 out now.
Like to get it down to .001 or less.

[Ognib]

 

At this point, with the chuck centered on the rotary table, I needed to center the chuck under the spindle.

The center bore on the chuck is 3/4" & I used a 3/4 countersink as my locator device & moved the tables around till it drops cleanly into the center bore.

Locked the X & Y tables at this point & mounted my work piece in the chuck jaws, centering it visually as closely as possible.

With the fine point of the countersink on my center mark in the layout, I rotate the table & observe the runout away from the center mark.

Loosen one jaw & tighten the one across from it, thus moving the workpiece a couple thou at a time....back & forth...round & round...tighten/loosen...until the pointer stays on the mark while the table turns.

This type setup is vital if the rest of the work performed on the piece is to be concentric around the center of the part being shaped.
