Hi all,

What do you guys use to cut aluminum spinners . I have a scale Y/A spinner that I need to cut for the prop blades. Would love to hear your technique!

Thanks - Adil

A Dremel tool and a lot of patience

what attachment do you use in the dremal tool??

sanding drum (small one with coarse sandpaper) followed by a balancing act compliments of DuBro.

SAnding drums wear out too quick. Do the bulk cutting with a metal bit. (Watch those fingers!)

True, if you have a lot of material to remove. Good point.

If I already have the spinner I use a dremel and a polishing stone. If not, I order my spinner and request it to be cut to accept the APC propeller I am using.

Adil, I use a pair of "nibblers" to remove most of the material and finish up this a jewlers file. You can get a pair of nibblers at radio shack.

I cut 'em with a metal bit dremel, and finish 'em on the one inch sanding belt (med grit). It's about ten times faster than doing it by hand.

Yes, the metal Dremel bit will make short work of it.

Having been in machining most of my life I suggest you get a 1/8" carbide double cut burr with a round end. They are moe expensive than steel but will last many times longer especially on abrasive material such as fiberglass. The round end allows you to drill straight through when needed and also helps in smoothing things out. If you can get some tap magic squirt some inside the spinner and it will keep the burr from loading up with the soft alluminum. Kerosene will also work to stop the loading but is more flamable. You can purchase the carbide burr at many hardware type stores or tool stores. Next to my dremmel drum sanders for wood this is the cutter I use the most.

Thanks to all the folks that took the time to give great advice. I have ordered some steel and Carbide burrs and a nibler as suggested and am sure with some patience will get it done. I'll let you know how I make out in the future.

Thanks again,

Adil
