Too much grease!!!!

Hi Ruth,

I have used a link belt on the Reeves drive of a Jet 1236 with no problems at all. Lowered the low end RPM some by playing with the length of the belt. ;)

Sorry fellas, I think Madge was hyping the green stuff -- Palmolive which is not recommended in LDD circles, or squares for that matter! *G*

Dear Mr. Thorvaldson: "rca" is the sole property of the Radical Corporation of America. Just a friendly reminder, not a threat, that your usage of our logo is actionable. Ignoramus lex est non excusabit and all that jazz, including trying to sneak our logo into lower case letters (see Carpe Lignum vs carpe lignum et al). We are not just blowing smoke nor soap bubbles here, and as for being excessively greasy..... tell that to the General. What did Ruth know and when did she know it?

Fortiter,

Dear Mr. Plonk,

Thank you for your friendly,minacious letter. Unless you have patented or copyrighted "rca" as well as "RCA," we find you edging into damnant quod non intelligunt. This is of no importance whatsoever to the LDD movement as we can bubble up wherever we choose. Insofar and whereas you seem to be representing RCA, might I suggest your organization look into the purchase of a case of LDD. In the case of radicals, we find it efficacious in cleaning out their mouths and a sovereign remedy for bowel cleansing.

Ad astra per LDDeum,

*************************** Dan, Which way did you go with the belt length - longer or shorter. Watching mine, it appears to be a little too long at the minimum speed. I had wondered about using a shorter belt, but wasn't sure.

************************* Dan, With the reeves drive, one pulley opens as the other closes. If, in the lowest rpm position, it's opened as far as it can, how does the belt length change that? Am I missing something?

Ruth -- I've had a Reeves drive apart...

One pully is the master and it is forced open and closed by the lever.

The other pully is a slave and it is held as closed as it can be by a spring. The width of the belt counteracts the spring and holds it open, some.

So if you make the belt longer, it would change where the belt rides on the slave pulley. It would ride farther from the center (given a single position on the master) and so the slave pully would be more closed for the given position of the belt on the master.

Clear as mud?

Going further, if the belt is too short, it will bottom out on the "slave pulley" (motor pulley) before the lever is able to force the belt to the outer rim of the "master pulley." This will mean the lathe is running at a higher speed than its absolute minimum. Putting on a longer belt allows the lever to move over more,, so the driven pulley is larger, and the lathe slows down.

The advantage of link belt in this application is that it allows you to tune the belt length in 1/2" increments (vee belts come in 1" increments. It is also possible to change the length of a single piece of belting, instead of having to buy several belts to do trial and error.

I will second the - "You can run link belts in reverse" opinion. I do that on a special piece of equipment I made to thread the inside of very large nuts. By running the belt in reverse - I could get more power out of it - due to the way the ends of the belt were trapped in the V pulley.
