Passive Radiator CSS SDX10 Design and Build

Anyone have scratch hiding tips? The kiddo wanted to “help” and grabbed my kutzall rasp.

Slightly damp rag, Clothes iron. Put the slightly damp rag over the area and steam up the area. Sadly you can raise the grain and sand it smooth, but, you will see the scratches as a different colour area. Been there, done that.

My kids are 32 and 31 years old

Nephews and niece are 10 and 9

They washed my van with rocks once. Yeah.

I was planning to do that, then sand in some of the finish to make a slurry in that area.

If I can’t make it presentable, no time like the present to learn veneer work

Depending on how deep the scratches are, you may be able to raise the grain enough and pretty much hide the scratches completely. No filler will make them disappear, unless you are willing to paint in the graining.

By the way, that iron and slightly damp rag trick has made me considerable money fixing white rings on tables.

Bunch of work travel and life stuff kept me out of the shop.

Got better dust collection kludged together and everything flushed up this afternoon. Going to start on the roundovers tonight, hopefully.

 

[EngineerNate]

First box rounded.

 

[mwmkravchenko]

Now for about an hour of sanding! Going to look good. What's your finish going to be?

Fiddes hard wax oil.

And then there were two.

Glad I did this outside. The dust collection worked great on the flush trim but the lower shroud didn’t really fit on the 1 1/2” roundover bit.

 

[EngineerNate]

@mwmkravchenko steamed the scratches as well as all the dents/dings in one of them tonight to prep for sanding. Also went over where the bearing on the roundover and flush trim bits rode on the wood and compressed it a small amount. Almost everything came out pretty well. I think the scratches my kiddo made will hide well enough.

I used this r/c airplane covering iron I’ve had since I was ~15. Most use it’s probably ever had.

 

[EngineerNate]

Sanded and ready for filler work before finish.

 

[mwmkravchenko]

A proper and thorough resurrection!

Number two sanded up. Don't think I'll ever perfectly get rid of the line where the bearing rode. Masking tape next time? Really happy overall.

The bearing stopped spinning and acted as a cutter? Usually that the washer between the bearing and the router bit that causes issues like this. Sometimes I remove the washer.

Now you apply some finish and really look at your work

Didn’t realize I needed to center my guide bushing and had to make my cutout a little extra big. Good thing it’s on the back.

You learn something new each project.

 

[EngineerNate]

If you do it twice it’s a choice, not a mistake.

Helped me hide some tear out from the cnc.

 

[Yasuo]

This looks great!

That is a design refinement sir, tut, tut.
