Old School with Sioux

[Henry K. Lee]

Sometimes old is better in my opinion as the quality in hardness, interchangeability, and self sharpening is unmatched. Been collecting parts for some years for my new up and coming interest...., hyper balanced engines. Everything starts from the inside out. Valve precision is a key factor with porting. Love to see an engine run with a glass of water on the top with no ripples! Watch a true Rolls Royce, Maybach, or M3 BMW, etc.. Pretty awesome!

[Henry K. Lee]

Don't forget shaving and balancing a flywheel and if it has new super hard seats.., special cutters are needed to cut them out!

[Dallas Landers]

I have to get to dim dar hills and see your shop Hank.

[Henry K. Lee]

First of all.., it’s a playhouse so get yer southern pronunciation down Pat first!

Got have a southern stamped passport! I will vouch for ya! Let dim know I said “Dah Huh” and he’s a good one!

[Craig Raynor]

Looks real nice Hank I am applying now for that passport and I hope it will be accepted at the door to your playhouse someday.

[Don D]

Craig,

I spoke with Hank on the phone just yesterday and while we didn't discuss the elements of the "Southern Passport" appplication process I suspect it should include a test. One question could be, What did Tenna See? Feel free to post your best guess.

Best of luck,

Dom

[Dan Hatch]

You Yankees better be careful. From Hank’s place he can see you coming a long way off!

[Dallas Landers]

I will tie the coon tail to the antena on my truck . Should get me in.

[Mark Gregush]

"What did Tenna See?" It saw members of my Grandmas' family leaving the hills and moving to Oregon and Washington!
WOW, nice work on transforming that Sioux grinder!
I have the same Sioux valve grinder. Mine is still wearing about 95% of its original paint. Without going out to look, think it is a Catalog number 650. It had a new stone installed when I got it. Only problem is, the outer diameter is now too small to use the stem grinder. With the chuck installed, the stem holder can only go on one way, putting the Vs to the outside of the stone. The stem ends up with a nub on the end. While I don't think so, the stem holder that came with it, may be the wrong one. The stem grinder is missing the stem clamp/hold down. It also came with the stone dresser, the allan tool with knurled handle for adjusting the collars and one other piece that don't recall its use. Because this model is dry grind, takes a little more time to grind the valve and stems, allowing a cooling cycle.
Nice roller balancer! I would trade my knife-edge homemade one, any day of the week for one like that.

Nice work on that Sioux, Hank.

Where can I obtain belt material or the actual belt that rotates the valve stem chuck? Mine has a round leather belt, hopelessly frayed and crumbling, that needs replacing for the unit to be functional. Thanks, jb

[Henry K. Lee]

Beam equipment has stones and some parts. eBay is another source on occasions. You can use a small serpent belt and invert it for your stone arbor.., Dayco # 240K4.., or try 5040240. Lower belt from cross drive up to chuck, belt # 4L220, from motor to cross outside belt, # 3L300.

[Mark Gregush]

Mine was replaced with a large reddish colored one, like an O ring. There are some parts on eBay. While in my post above I show the Catalog number, I think the correct number is 620 for parts. Model numbers changed, but some sundries remained the same for a long time.

Henrys post above mine indicates that a small serpent belt can be used. That would give more options. Great and thanks.

Mark, Hank, thanks very much, jb

[Bill Coyle]

JB,
My Sioux's leather drive belt came apart like yours. Since it broke while I was in the middle of a project.... I found that a spare "carbon center" spark plug wire worked as a good replacement. Just used the original clip from the leather belt to fasten it together. It's still working with the temporary fix. Bill

[Mark Gregush]

Yes, nothing like a temporary fix that is permanent!

[jab35]

Thanks, Bill. I know there's a round solid polymer belt material that should work like your wire, but last time I researched it, I couldn't just buy a short piece and I didn't have access to the splice welding device. I think that polymer belting and the original 'staple' would probably be ok in this application. Your plug wire fix gives encouragement! And does that belt have to be joined in place or can you easily dissemble the drive and install an endless belt without having to join the ends inside the the frame?

[Henry K. Lee]

The V belt number 4L220 works in its place. Sioux went to this later, but used the same pulleys.

[Harry Lillo]

Hank,
Maybe it is or isn't a T related item; could you tell us more about "Hyper Balanced" engines?
Harry

[Henry K. Lee]

Well it is actually T related. Because a Model T was the first production automobile to have others make balanced items to make it smoother and more efficient. A hyper balanced engine is where all components are of equal value in weight, flow at ports, and in some cases intake runner length with exhaust with “chokes” installed. Any differentials are made up by individual spark plug gap, and or shimming the spark plugs. In some cases a counter shaft is used as a shock absorber so to say with hydraulic fluid to take up torque at various rpm’s. Sounds complicated but it is a procedure in perfecting the smoothness which in turn eliminates drag and cylinders fighting each other. By counter acting negative forces we increase fuel mileage. Just therapy for the brain!

There are presently modern engines in development not using a camshaft at all, but instead a solenoid system with pause and delay cycles. Formula 1 has a testing circuit at the moment. They are using capacitors, etc.This in turn normally will have the engine gain unGodly amount of power due to no drag caused by the valve train. I am going with mechanical options, called multipliers.

There is currently a Porsche in Germany, boxer 6 cylinder under wraps running a 100 mph at Nuremberg constantly getting 38 mpg. How? By keeping the throttle open, but changing the lift and duration of the valves electronically once the desired speed is reached.

If an engine or any rotating assembly attached to it vibrates or flexes, the vibration is consuming some of the engine's power. Flexing in key parts, such as crankshafts, camshafts, pushrods, blocks, etc will distort clearances and affect things like valve timing and piston timing. Holistic blueprinting of every part of the engine assembley isn't easy or cheap, but it can give remarkable results. Rolls Royce used to attempt to hold everything to very tight specs.

[TXGOAT2]

A camless engine could produce both very high horsepower and high torque from a small displacement. Intake and exhaust tract tuning, perhaps with variable intake tuning, can raise effective compression ratio and volumetric efficiency. Getting most of the vibration out of a T engine would probably free up 5 HP or more.

[tdump]

I was given a valve grinding machine a couple weeks ago.It is red in color for what paint is left.it is not quite that rusted but every part is stuck. all the hardware WAS with it but got trashed before my neighbor could save it.
I need to go get the heavy turkey!

[Bill Coyle]

JB, Mine has a cover that opens to allow access to the belt. I didn't try, but I'm sure you can install a standard belt. Bill

[jab35]

Bill: Thanks for the pic. jb

[Dropacent]

I’m working on a hypo-balanced engine. Been trying to keep it secret but not about to let Hank get one-up on me. Here’s my equipment. I’m still searching for 4 iron pistons at least a pound different from each other.

[Henry K. Lee]

Tim I am digging in my scrap pile and weighing just for you! What are your weights now?

LOL

[TXGOAT2]

Can you adapt Yugo parts to a T engine?

[Henry K. Lee]

Yes! Melt them down, add alloys for stronger material! Or…, YoU-Go-and get an-Other!!!!!

[TXGOAT2]

OK, melt one Ural motorcycle together with one Yugo and blend well, then fold in a few dozen Chinese rubber wrenches...

[Dropacent]

When to see the before and after of what henry did to a good old American tool, why would anyone ever walk into a harbor fright store. Good on ya, Hank!

[TXGOAT2]

Many Harbor Freight hand tools are actually better quality than the more colorful and expensive PlaySkool tools! (Seriously, they do have some good stuff for the money)

[Mark Nunn]

Thread drift, for certain... I find high-quality and lower-priced wrenches and sockets at Tractor Supply. If a farmer breaks down during planting or harvesting, he can't afford to have cheap tools. If he does, he's out of business.
