add lock collar and bearing, is it safe?
I see that they are sold but wondering about the safety of adding a lock collar and bearing to a 1/2 spiral bit for pattern finishing. I also would be worried about having that much less of the shaft to put into the collet. The spiral bits sold with bearings are mucho $$$. Thanks, Tom

how much shaft are you inserting into the collet now???I see that they are sold but wondering about the safety of adding a lock collar and bearing to a 1/2 spiral bit for pattern finishing.

adding a bearing is safe as long as all the components fit...
why not use a helix bit???

they give/do a very clean top edge and w/ the pattern clamped onto the bottom you get a clean bottom edge also...
the pattern behaves as a backer board...
I'm with Doug on this...a 1/2" ID bearing will give you 3/4" OD on the bearing surface. Depending on what you're doing with it, it could require you to use a big bit.
Guide bushings will allow you to use a smaller diameter bit.

still, pattern and finished product will be off set requiting a smaller pattern...I'm with Doug on this...a 1/2" ID bearing will give you 3/4" OD on the bearing surface. Depending on what you're doing with it, it could require you to use a big bit.

use the Helix and existing pattern...
Generally when a bearing is on a straight bit it matches the O.D. of the bit. Yours wouldn't do that so it depends on what you are doing whether that is workable or not.
I guess I don't know much about Helix bits. I'll have to learn. Thanks
Also really good video on bushings that will make me reconsider my options. ThanksUse a template guide bushing
