what kind of knife for small curves?

[LFNfan]

Hi
I'm going to be scratch building from plans and there are some small curves that might be tricky to do cleanly with a utility knife / razor blade.
Are there any good tools / techniques for achieving these curves neatly?
I've attached a 1:1 pic of the sort of thing I'm seeing on the plans.
Maybe 'best endeavours' is fine and I don't need to worry!
Many thanks in advance

I second this. That’s a standard Xacto #11 blade. Don’t cheap out on off-brands, the Xacto blades are cheap enough. Buy at least a 20 pack of blades, if not the 100 pack. New sharp blades are luxurious.

That is basically what I use as well. Works well for small curves and it gives the cleanest edge out of all the knives I’ve ever used.

same here, it is cleaner if you make a few passes

Yeah for sure! @LFNfan I just cut those clearance areas for the control horn square and it looks fine.

And sharpen or change the blade as soon as you notice a reduction in quality of cut

Brilliant - thanks all.

Separately, Tx, Rx, servos, ESC, props, charger arrived today. Exciting! But batteries and motor shipped separately and not yet arrived. LOL. Typical!

...I don't need to worry...

Yes, I would not worry too much about something like that. It's not critical to get exactly correct.

good to know - thank you. It all looks the same to me at the moment!

Just use whatever nife you got to cut the 2 straight lines and then use a push pin to poke the curb line and then just push it out.

Sharpening is free…….. Now I know what to do with my x-acto.

Actually yeah! I have used my broadhead sharpener before. (It isn't as good as a new blade though.....Or maybe cheap sharpeners don't pair well with cheap blades...)

I know someone who makes knives, I’m sure they could help me out.

A 100 pack of blades is $24.61 on Amazon, so less than 25 cents per blade. I used to sharpen my Xacto blades, but even with a good quality tool sharpener, I couldn’t get close to a new blade. Spending a quarter on a new blade is so worth it.

I guess that's not so bad when you think about it.

Well back in my day, we didn't have blades, we had to make or own out of flint. Yes, those were the good o' days. We would even collect pine tar for glue. And before global warming, it was soo cold, oh how the snow would blow. And we walked to school, up hill both ways.

At least that is the way I remember it. 🤥

Sure you did.

Uh huh, maybe for FUN.🤣 Flite Test wasn't around then...
