Panks broadening horizons

That picture of the crank is WRONG. It should be IN THE GARBAGE CAN.

many people have bought cnc equipment thinking well you don't have to be a machinist! well not only do you have to learn a new language you will also need to invest and become trained in computer aided design,expect to spend roughly $4000.00 on this software so you can develop a three dimensional model of the part.
    next you will need to invest in a computer aided mfg. software,expect to spend $15000.00 on this product so you can develop a tool cutting path.these two tools will require many hours of training and exercise to become proficient.now you should also have available software to evaluate your part design,finite element analysis to locate concentrated stresses,without this tool you may be creating a lemon and not even be aware of it! expect to pay upwards of $100000.00 for this technology and many people spend years in college to master this software.
I am not trying to discourage you but as with anything there is more to this than it seems,there are many late model machines for sale because buyers were not aware of the knowledge required or other costs involved in this trade.
I for one will be looking forward to your newly designed parts for puling

the tractor in the picture don't have big enough tires on it to need more than 60hp to win looks to me

Pankey went over this when your pal Andy was recommending just turning allis crank down to farmal h rod diameter but the h rod is narrower. Butch sometimes Pankey says going forward is backing up tarbills motor did teach him a thing or three . one thing it had a large duration relative small lift cam from comp cams . didn't lug well at end of pu all but ran strong enough in the middle to get past everyone to be a points champ . so Pankey goes with more duration now and even though Marty says its all wrong well it got past two of his this year So is this the cam I ended up with?  small lift, lots of duration?   Was it in Tarbills engine too?  cant remember

according to Mitch you have the camshaft that jt Richardson ground that's the same profile barney Taylor had jt grind before jt passed away . the can in tarbills engine was ground by comp cams not a Richardson grind.

That's to bad, machining parts, building engines is precise work. Can you take time to explain how a narrower journal requires more welding as in your previous statements, or are you going to side step that one after you realized you have no experience or knowledge when it comes to crankshaft work.

Pankey says sure custumer wants to use 8 inch long h rod which by memory is 1.455 not exact from memory wide his crank journal is machined to utilize the allis factory 7.5 long rod with a width again from memory not exact but around 1.735 wide . so you have .280 difference in width if you don't weld its going to be hard to keep oil hole covered unless you design a piston guided rod and then it will be still hard to maintain oil pressure without welding

About .800 difference in width

I'm guessing we have it all wrong here, considering the fact that Pank now owns (supposedly) a machine that you don't have to be a machinist to run, my guess is, he's going the distance and will be sinking dies to have his own custom cranks forged, the Mazak probably has a button that says "special Allis crank" and another that says "please select a stroke" and then "Run" and viola!!!! out comes a set of dies ready to head to the forging foundry that will ship a completed custom cast-forged crank in a matter of days. Pank now admits to "not being a Machinist", he can add to his resume "not being a Die sinker" and with the help of Mazak language, conquer the manufacturing world and performance industry as we know it. I'm sure the TVA will give him a few days off in December so he can show his stuff at the PRI show in Indy.

I guess I'm just a little peeved that I went through a six year Apprenticeship, four years of College, and about a dozen Journeyman reviews to achieve Journeyman status, and Pank goes out and buys a machine that does it all for him..... I wish I had one CNC as smart as that Mazak is supposed to be. And I've seen all the "Programmers" who have no machine experience I care to see and the results of their efforts. LOL  It reminds me of a IMTS show in Chicago a few years ago where Mori-Seiki had a forging die for a crankshaft on display, I was looking at it when a 30 year old Salesman approached me and commented on what a marvel it was and asked me what I thought about it. My response was that I was wondering about how many people in attendance at the show that day could produce this without a CNC machine, the salesman stated that this would be an "impossible task without CNC capability". I asked him how he thought this was done before the advent of CNC and received the "deer in the headlights look". Never did get an answer.

Butch Mitch didn't want to teach you how to balance he wanted to tease you and Marty after all if he had made a teaching video it would have had more YouTube hits than a slow talking yank and a Giddings

Butch he has done shown you he has a crank balancer ,grinder and press it would just make you more envious if he showed you the welder .its close to happening

 Me too Ken. I worked with the company guy and our programmer setting up a new slant bed Okuma lathe one time. It took me 3 days to convince them that no matter what the claims were for the machine, you can't cut a 5/8-24 thread on a bronze casting at 3500 rpm. It worked great when I slowed it down to about 1500 
 I don't know if it is possible now but back in the 80's that top of the line technology couldn't do it.
 I really want to see that Mazak right after the first part is run thru it.
 

Yep, working with stuff like hastelloy, or any other exotics is about the same. Take fast light cut and burn up tooling all day or snag a chunck with a moderate speed and good feed and get the job done.
