Justin,

Go to the Artsoft (Mach) website, join and go to the general topic. A guy there called 'Hood' has converted lathes as well as others there. They can and will help you.

Have you tried making/using a spade bit for this? A Ø 0.028" (#70) piece of hardened drill rod or carbide (special wheels for carbide as you probably know - green) - grind the sides away equally...

A wood bit is somewhat different than what was being discussed here because the tip is ground completely different. The tip is ground to a needle point but the flutes are left long on each side but...

Boelube is about the best coolant for composites. It's very clean and non polluting for the fiberglass....

These are reasonably accurate machines for the money. I converted an Enco floor model knee mill a few years back with headstock similar to the g0728. At that time there were no other alternatives for...

Clean both surfaces to a water break then with precision, bond the parts to a substantial sub base with the glassy hard curing polymer of your choice. Clamp conventionally, mill, inspect, and demount...

Neil,

Try blackening those engraved grooves or etched grooves, then polish the brass with a firm felt wheel and some rouge. Or use a syringe to place some black in the grooves. We make a brass...

A broken bit would need to be reset once or twice with either sharpener in both axis, and length to achieve a tip angle required for the work. A light sharpen of the cutting edge would usually only...

mbelfer,

The depth of the 60 degree side is .140". But a straight edge across the roller perimeter to the bit tip will be as accurate as the setting tool. That would match the frame angle. Then;...

The setting tool merely sets the bit tip by being parallel with the frame plus the exposure dimension of the rollers, so the frame angle is your key ingredient for drill bit tip angle....

The radial runout of a single row ball bearing must be designed into whatever spindle systems use is intended. Unless your query is misunderstood, the use of a double row ball bearing or externally...

I believe you have had enough 'fatherly' advice, now how about something constructive?

You're probably familiar with how these rails are constructed and what you need for rail supports. You say...

Look at Balsamans pictures.....

Ken Hurst is apparently prolific engine builder and is an inspiration to all who have an interest in IC engines. His site with the sights and sounds is a joy to visit and I have shared his 'sounds'...

So Balsaman,

What are you saying? I understand the 'inexpensive software' part but are you inferring that 'good' or 'better' (expensive)software uses the serial port? The question was good and I...

Ever heard of using pulverized glass for a cover for melting and casting tin bronze?

That's all I build, I'm not a fan of the airplane engine (two cycle).

Balsaman,

The picture of the crankshaft is not mine. That type engine is slow turning so the flywheels usually carry the counterweights for engine balance.

I'm happy with what I see; I'm...

I will measure and give dimensions as well if needed... as you can probably see, the pin chucking device has the basic 118 degree Tee shape for grinding the bit to that angle - more- let the bit...

The very small bits can be sharpened on a setup that includes a pin chuck with a Tee shaped body that includes a couple of small rollers at 180 degrees. Included in the set is a loup to see the bit...

Well too, you must also keep in mind that there are different types of carbide inserts. That is, different hardness and structure for specific materials; an insert for stainless will be quickly...

Hello,

Sure was hoping for more activity here towards IC engines. I would enjoy seeing other's accomplishments since mine are at an all time low after starting on a mill-NC conversion. I had...
