Drive Spur

It was leaned that using a larger spur may not always solve this problem. Should you not find a larger spur quickly. You may want to try the following: Locate the centers on both of the ends of your piece of work and drill a

1/8" pilot hole Take a fostner bit of the same OD of your spur and counter bored X 1/4 - 3/8 deep one end of your blank. Now mount your piece of work by inserting the spur in the c'bore hole. Secure firmly, rotate by hand first until your satisfy with the centering, wobbling and adjusting of the live center as needed. Then start at your lowest RPM. Others are using a pin chuck with a locking pin inserted. The principle is the same as counter boring for the spur. It may be more suited for larger pieces. What they do is they drill a hole of about 1" deep and insert a pin mounted on a Morse taper shaft to suit your lathe. Some people have custom made heavy duty spur and still have problems. This is more so when using end grain black locust. FWIW

I noticed that the large spur drives from Best Wood Tools was suggested. I have one of them, the two spur variety, and it works quite well, much more grip than the small drive, especially with large logs.

Where would a person find a large drive spur? I've picked up an ungodly amount of walnut and cherry and need to get it roughed out. I would like to use a bigger spur than the one furnished with my DVR to rough it out.

Thanks Bruce

Hi Bruce, Hiyadoing? I know you asked where to _find a big spur drive, but you might want to make a 'Archspur' drive. Put 3 or 4 sharpened short bolts thru small diameter face plate holes. Add washers and nuts. They can be pointed, but I prefer to grind the ends same as on a store-bought spur drive. If your agnostic walnut & cherry warrants your troubles & woe, consider welding a 2 to 3 inch diameter X 1/4" slice of soft steel bar to a spindle nut. Drill & tap for the bolts so no nut is needed and the wood can register against the disc. Also, you can use a thicker disc and drill bottomed holes from the wood's side. That way short pins that need not be fixed can be used. Or, go buy something that works! :) Regards, Arch

Fortiter,

In one of Raffens books he explains to use a facce plate with two bolts comming out of it nutted on the work side. the ends of the bolts are sharpend to a point and engage the wood. This could be used on irregular surfaces. I guess the distance between the bolts would depend on the size of the face plates.
