Im in the middle of making my third member. I wish I didnt see this LOL

[Ognib]

Any in progress shots of said 3rd memb?  I'm always looking for clues.

Ray, I don't understand your method of alignment with that piece, can you explain?

....."porn", that piece is sick!

 

[Ognib]

Just a pic I found online. Very visually impressive.  Probably cut on CNC.  I definitely don't have the skills or equipment to pull that off.

This looks good to my eye for the differential on tire size for a street car.

Don't care much for the back panel treatment on this car below the feature line, but other than that, it's got a real nastay vibe about it.

Sketching out some ideas. Drawn to scale.

[Twokidsnosleep]

Ok now you will have my undivided attention.

THIS is why I want a mill....custom wheels

[Ognib]

Well, it's time, so hang around & we'll see where it goes. 

I've been buying all my material from an old man who owns a huge metal recycling business.  He let's me in to dig through his bins & sells to me for $1.00 lb.  Gotta get back out there & find a few chunks that are big enough to whittle these wheels out of.

The wheel lay out looks great. Whats your thoughts on finish?

That is great, gotta love that kind of arrangement...I need one of those old guys like that with a lumberyard

I like the look of the raw machine work in the metal.  To my eye it has greater visual impact due to the varying textures  & contrasts & reflections as the piece changes angles & shapes...where very bright, highly polished work tends to get lost in itself, if you will. 

I bet you have been buying some lumber recently, Scott.  How's that going?

Down side to digging at the salvage place is you never know what they're going to have...it's random.  Last time there I scored some beautiful 1/4" plate & some 1/8" plate  in 12 X 18 dimensions...enough for years supply for under $20.00.  Time before that, mostly what they had was pipe & small round stock.  Of course they've always got beer/soda cans by the hundred thousands & plain old metal junk.

 

Got 2 sets of front tires today to choose from.
These are real tires, for RC cars...meant to be drifted, accelerated hard, etc...They look & feel fantastic up close & the quality is outstanding!

The first is called the vintage racing tire & is slightly the wider of the two.



This one is about 1/16" taller & has a V groove tread pattern that is similar to the back tires, which are still in transit.
This is the tire I'm going to use...unless something else comes along that I like better, of course...had to see both of them in person to know for sure.

i thought you wanted to machine your own tires?

[Ognib]

Hi Dave,

Ya, that's something I'd like to do.  My biggest google search recently has been on the subject of machining neoprene rubber.  There is an interesting thread on "practical machinist forum" on the subject...

http://www.practicalmachinist.com/vb/cnc-machining/questions-about-machining-neoprene-rubber-211532/

I'm still new to the machine shop side of things & my learning curve is kinda slow at times.

Want to keep making progress on the model so I'll put the best rubber I can find on it until I can provide something better to use.

Ognib, I post some pics on my Camaro thread in the drag racing section.

Got the back tires today.
Went to the salvage this am & made out like a bandito!!

They didn't have any bar stock that was close in size for the wheels, but I scored this nice piece of 7" round. It's 3 1/2" tall. Enough for the big back wheels plus extra for in the table & a bit of space.
Drew some rounds with the bottom of a rattle can...a bit big, but gives me room to tighten up my setup as I turn it down to specs.

I could have gone somewhere else & paid retail for some material...at $1.00 lb for salvage, I've got more time than money.

Here's the new back tire next to it.



Just keep trimming it down with the bandsaw.

[John Clutch]

Wow. A buck a pound. I could only wish here !!!

[Ognib]

ya, can't beat the price.

When I factor in the time taken to trim it down into workable blanks, I think I'm still beating the retail cost.

I am going to step out this morning & get a coarser, heavier blade to work it with.

It's an on-going education. 

Hap sat!

[Twokidsnosleep]

Hey Ray about the bandsawing metal

Is it a special blade you are using, the tpi looks higher than my woodworking blades. I am sure I can convert my Grizzly bandsaw to cut metal with just the right blade

 

[John Clutch]

I believe the general rule is 3 teeth minimum on the work at all times. 

[John Clutch]

More teeth equals smoother yet slower cuts, less teeth is rougher yet faster cuts.

[Ognib]

The current blade is a 14 tpi raker blade, rated for wood & soft non ferrous metals.

It works great for the hardwoods in my guitar builds & has been good for the smaller pieces of aluminum I've cut to this point.

For cutting this big piece down, I'd like to move a little faster...thus the addition of a thicker blade with a more aggressive cut.

[Ognib]

Got a plug hacked out that will fit on the rotary table...good thing I'm not building 1:4 scale...I'd need a bigger machine.
Faced it, laid it out for center & drilled the center line 2 1/2" deep.

[10thumbs]

Ray that's a serious chunk of metal there.  Looking good.

[Ognib]

Hi Michael, thanks.  There's a wheel hiding in that chunk of metal...see if I can find it.

 

Nitty gritty...down n dirty...gettin there.

[Ognib]

It's all round now & getting closer to spec.



Cutting fluid & acid brush.
I keep a film brushed on as I'm turning the table.
