sanding fillets

[hct236]

Has anyone tried to use a dremmel tool and the barrel sanding attachment for sanding and shaping fillets?
thanks

I tried it and it works ok. Not great through.

Best results I've gotten is to take care with making the fillets while they are wet.

After they dry, 60-80 grit sandpaper and your thumb does a good job. I bet a thin magic marker wrapped in something soft like foam rubber or even a thick towel would work too.

Do you think a wine cork is too small?

that might work. Just depends on well it matches the shape of the fillet.

Probably would work best if you took it out of the bottle first, too.

Did I ever tell you about my first game of horse shoes?

I keep several short (+/- 2") peices of various sized dowels available to save the skin on my thumbs. I usally cut those from used foam brushes. I also make small fillet using the regular expoxy fillers, but apply an additional / thinner layer of fillet using a more sandable fairing filler added to the mix.

microbaloons work great but they are that dark purple color. System Three make 2-part fairing/filleting material mix now in a brownish-tan color. You get two cans of like a soft putty and mix together to make your filleting material instead of mixing epoxy and then adding the filler.

But they don't offer the tan-colored filler by itself. So you might end up spending more for dedicated tubs of pre-mixed filleting material.

Glass bubbles work pretty good and are more sandalbe than woodflour but not as much as microballons. The glass bubble add a white tint to the filleting material.

I had the "Test Kit" from System Three's Silver Tip series. I tried the 2-part fairing sampler. Works good, a little too stiff for me so I thinned it a little with with some pre-mixed Silver Tip epoxy, much better.

how did the cured color turn out?

the morter tools block masons use work pretty good and you can get them for a couple bucks and different sizes.
