The diameter of the coils should be as close to the diameter of the pin as possible (within reason), and if you have half an inch of wood (or air) between the coil and bolt, or not, plays a difference too. You want to heat the pin to at least double over the epoxy's rated temperature, because...

They heat up the metals to the point they're glowing, so you're easily over 900°F pretty fast (depending on the unit power, size of the coils, and proximity to the piece you're heating, with solid units well over 1400°F in seconds pretty much). Mechanics basically use them just to remove nuts...

You can heat it up with an induction heater no problem, the same way copper coils in transformers induce magnetic fields by rapidly changing the electrical field, even though copper is not magnetic. The metal just needs to be electrically conductive, which titanium is. The type that mechanics...

I wonder if adding a ceramic coat (like they use for cars) would work good? A member of the club I'm at put it on his Benz, and it really stood out in the parking lot, and I doubt the clearcoats between the different cars were much different quality-wise, especially the friend's Benz being...

https://www.billiardshopgroup.com/product/original-nuclear-plate/ here is the link to the product you posted a photo of, but the same brand also makes these: https://www.billiardshopgroup.com/product/original-atomic-fibre-pad/ Both are made from fibers, the shop I linked is in Italy, so not...

Well, finally got around to it and hooked up a RPM controller to my router. Will be feeding it the failed house cue conversion pretty soon to see where the sweet spot for the parameters is, if it doesn't turn out to be an issue related to the router spindle runout, and the grind on the 4-wing...

Well...The update: I decided to not attempt the restoration, and since a few friends started to give me offers for it after borrowing it occasionally, I decided to let the mezz go and forced myself to make my first cue, since I'm without a breaker. I will see how my house cue conversion plays...

The top of the tooth on the centerline, with the workpiece rotating down into the tooth, or up away from it? I had it centered exactly, but I will also try your method. Still need to source some quality collets, I did manage to hook up a board with a pot so I can control RPM on the router now...

That's my setup, with the cutter I tried to taper with. I'll try hooking up a potentiometer to the router and see how that goes, I didn't even think about the router rpm being a factor, since it's a simple on/off 30k rpm type deal. But it does make perfect sense now that you mention it... I...

Hello all, I just attempted to taper my first sneaky conversion butt, and would kindly welcome a pointer in the right direction, as it didn't go too well. It was quite catastrophic 😆. I'm using a 4 wing carbide cutter in my router at 30k RPM, 800W, and while it cuts wood amazingly well, I...

I don't know how others do it, but I was thinking of doing it like this later this week: I will level my lathe table with a machinist level via 6 adjustable feet, then the lathe guides with a machinist level (using the bolt system mentioned in previous posts), followed by the lathe cross slide...

Interesting, I always thought this was a possible issue with a few setups I've seen, but I haven't heard of it happening yet.. Hopefully the lathe is still ok. I just finished welding my lathe table together last week, it's now fully bolted down, with the main reason being I made small...

Am wondering where did you get the nice polycarbonate joint protector?

Ok, just installed a bunch of elites today, tried out the SS on various shafts. PRO: The glue used in them is good, up to par with premium brands, no doubt about it. This was my main concern before ordering them. One tip out of 20 had a thicker glue line than the rest between one of the layers...

I will give my first impressions in about 2 weeks, ordered 20 and they are clearing customs right now. Have many shafts ready for them to be put on and tested. I have not tried ultraskins yet though, so I will be able to compare them just to the normal kamui/g2/milk dud stuff.
