They can/will, but you can prevent that by putting a little oil on them. They are not stainless for a reason, so don't swap them for stainless. Stainless cannot be hardened with the same processes that are typically used for steel bolts due to a low carbon content, so stainless bolts are actually much softer and prone to galling when compared to quality steel bolts. You will find (at least in high power setups) that you will need to get pretty serious when it comes to tightening those bolts.

These collets used to come with bolts that are a little on the short side and swapping them out for longer bolts helped prevent thread failure...I'm not sure if the bolts have been changed since then though, so take a look at yours. They are far superior to the Chinese collets in terms of run-out. All of the cheaper collets have a significant amount of run-out compared to these, which can lead to premature motor failure on high RPM setups.

A few of us with extreme setups have also found that the "fingers" of these collets will twist if the load/torque is great enough. They don't typically fail because of this but it does make the flex difficult to remove/install. If you have this issue, just consider yourself in the "gotta pay if you wanna play" club.

They seem to have long enough screws in them.

Ok I just noticed the blade so there goes that thought ha ha

I have those all over the place. I use 12 of them as shims to line the hatch up for the hatch bolts lol.

Mount tacked in place.




And epoxy flowing

That makes sense, Keith. Same reason they don't use stainless for really tough tools but instead coat the steel with something to prevent corrosion. But what is a run-out?

Oh, i see. This is the problem most drills seem to have when the chuck wobbles or runs out. Thanks Keith, now I know the technical term for this.

Totally off topic and not meaning to clutter the thread, but would anyone happen to know of a high quality cordless drill that has no run-off? What do you guys use to drill precisely?

[kfxguy]

And 4 hours layer we peel the tape while the epoxy is still semi soft

A well set up lathe is the only tool for the job, tailstock drilling slightly undersize then tailstock reaming the hole circular.

You have more chance of re-writing the bible by tipping cans of alphabet spaghetti on the floor than you have making a decent coupling with the best hand drill ever made.

Very clean man I admire your work

Motor mount looks good!

Thanks! Be watching this evening. I have a different idea on the stuffing tube mount I'm going to do. Will look better and be stronger

[kfxguy]

Didn't get to this as early as I had planned. I did get the pass through for the stuffing tube done tho. I'll have to get up at 2:30 to peel tape lol. I have to wait 4 hours before I can peel tape.

[TheShaddix]

Is this some special masking tape you're using? Or just generic stuff from Lowes, etc? I find that my epoxy goes right through whatever tape I'm using.

[monojeff]

Looks like frog tape.

[rearwheelin]

That collet is almost as big as the the motor !
