More fuel to the fire - Has anyone ever sharpened their prop-reamer and if so just like sharpening a knife or lawn-mower blades? Mines seems to be a bit dull....or should I just purchase a new drill press ;-)

RE: reaming prop
 

New drill press!

Not practical to sharpen reamers.

RE: reaming prop
 

it would be alot cheaper to just get a new reamer

RE: reaming prop
 

New Drill Press.:D

RE: reaming prop
 

New drill press AND reamer.:)

RE: reaming prop
 

New drill press, drill press vise, fractional, lettered, numbered and metric drills. Heck you have the excuse, get yourself a combination milling machine and drill press.

RE: reaming prop
 

Got the lettered and numbered bits, any recommendations on vices? Unlike R/C, Golf, Beer, Meat loaf, Mashed Potatoes, Pecan Pie, etc....

RE: reaming prop
 

I believe the new Corvettes are the same Bruce. Oh, and Kurt makes a nice vice, but not for a drill press.

RE: reaming prop
 

Shoot, and I could have saved myself the cost of a drill press had I seen this thread first! :D

RE: reaming prop
 

my bad... i forget that not everyone has a full fabrication shop to play with. guess that's why my friends are always asking me to make stuff for them.

ps. whatever you do, don't try to hold the prop in your hand and just run a drill bit the correct size through it. I have been doing structrual repair on fullsize planes for 13 years and the first time i ever put a drill bit into my flesh (or anyone else's for that matter) was a couple weeks ago doing this. I didn't think the plastic prop would have enough bite to "thread" the drill bit through it right into my hand. it did. ouch. worse part is like i said, i know better.

RE: reaming prop
 

Maybe I'm way against the grain here, but I've never used a reamer, don't even own one. I also have used my trusty drill press with positive results. ;) BTW, drill press was a gift a long, long time ago. :D

But being this is the beginners forum, I'd recommend getting a prop reamer.

RE: reaming prop
 

Just make your own props with the correct size hole! LOL
Just a little Christmas humor.

RE: reaming prop
 

It's a tad expensive, but in the long run it will save time: You can buy a drill bit with the tip smaller than the rest of it and just the right size to fit in the original prop hole. Then use that in a drill press. Clamp the prop in a drill press vise. I got mine from B&B Specialties, which advertises in "High Flight" and I think in other modeling magazines, too. Of course, you may need more than one, though I just have one in the right size for my larger engines.

This type of drill bit works very well with wood props. It is important that the drilling process is well controlled, because if the bit grabs it can cause a "check" in the hub of a wood prop that can lead to prop failure.

RE: reaming prop
 

Yes, using a drill. A drill press is best. A hand drill, crank or electric, will work. Here are some tips about prop holes that can enhance your sport flying.

The above information concerning using the drill press is mostly all good. Use some common sense care and don't get in a hurry.

If you use a hand drill, secure the prop and use slightly larger drill bits each drilling. As said above, the bit will tend to follow the hole. Let it do so. Then by using several drillings, each just a tad larger, you will get a decently straight hole through the prop.

If you should get the prop hole too large, simply cut yourseld a strip of masking tape, the width slightly less than the prop. Wind this tape around the propshaft ,until you get a build-up that looks good. If the build-up of tape is too much, take some off. If you get too little, add some more. This will work for centering the prop, is easily adjusted or removed, and takes little time.

Now I have some experience in props from the time I was 8-9 years old when I carved props -- or some resemblence of a prop -- for a spark ignition engine and a CO-2 motor. Maybe not the most efficient, but it worked to "git 'er done."

I have a reamer on the worktable and one in my flight box. I much prefer the drill.

RE: reaming prop
 

Well, to be totally honest with you all, my reamer is one of those T-bar types and is not designed to fit in the drill press, if I even had a drill press. It has successfully reamed out...by hand... perhaps 50+ props for me over the past several years, and not a darned one acted up or was out of balance, or off center (as far as I know) in any way. The way I test them is to ream them out to the proper size, mount them on the engine and fly the plane.
