how about a Oklahoma,AR,MO,KS,TX,+IA GTG thread?

I was always told it takes a special stone!

Well I got the hard blue wheel in the grinder..

Not sure if it’s hard enough to grind carbide.

You would have to do some vestigating. I know I can't hand file the stuff!

 

[Semotony]

I’d think you could..

Or does the carbide tear up your stone?

Due 2 earlier research & experience with carbide router bits. Diamond dressers is what it takes to impress carbide or sharpen I know there are wheels that could be used, but the other aspect is that carbide is brittle so doesn't hold an edge very well. The edge chips kinda rough IIRC

Morning midlanders.

I’m finding it difficult to get run time on the 200t rebuild.

Someone cleaned out the log dump on Saxton road. [emoji37]

But, not surprised since it’s that time of year.

How old is it? Looks like a neat project.

At 77cc you would need two of ‘em.

IIRC, a viable kart needed 125cc just to be average.

Used to be open kart tracks all over St. Louis county. Run what you brung. Then the liability lawyers got involved and effectively shut them all down. [emoji90]

Steve’s big Mono would qualify to power a kart. [emoji6]

Cobey, what's the number stamped on the carb and does it have an aluminum tag under one of the case bolts near the reed block? Sometimes that helps date them. Mine is a 1954 model.

Actually the AH-58's also were the "go to" kart engine for Power Products.
Power Products supplied drilled, lightened rods, open exhaust port cylinders with pinned narrower groove pistons and rings, twelve petal reed valves, and dual progressive Tillotson HL carbs where it started and idled on one carb then at 4,500 RPM the other carb kicked in. A lot of times port timing was modified by grinding channels in the top of the piston instead of the cylinder ports.
You could find a unicorn easier than Power Products speed parts though. [emoji38]

The carbide teeth wood destroy the dressed angle on the blue wheel in about 3 or 4 teeth. A green silicone carbide wheel will grind carbide but breaks down rather fast and will not hold a sharp corner. To achieve the sharp inside corner you desire a diamond wheel with a phenolic bond would have to be used. Even then you would need a way to dress that diamond wheel back to a sharp point on a fairly regular basis. Probably as often as you have to dress your aluminum oxide wheels you currently use. Your current diamond dresser will not dress a diamond wheel.
Hope this helps.

IMO the only good thing about carbide chain is it can handle dirt. Great for cutting roots and stumps. Cuts a little faster than a dull chain. The angles for grinding with a diamond wheel are more for cutter strength not cutting speed. I think the face angle is like 70 to 80 degrees. A normal chain is 55 - 60 degrees.

Yes..
My shop is now a “no carbide” chain zone..

I’m protective of my blue wheels..

Not upon me ! Came early for visiting doctor, blood test PSA to see if skin cancer is elsewhere? Now I'm having coffee and the more solid part of breakfast is inhaled. Over an hour to kill

Same here. Carbide is for firemen (cutting through roof tops and through walls). I wouldn't even use it for roots/dirt. And it is expensive and requires special sharpening stones, which are expensive. I have no use for it.

I would like to sneak a loop on your 7910 right before we race. Now that would be worth the price of admission.
