I plan to start repairing dings and nose jobs to my board myself ever since I've watched a friend repair it for me the past 2 times. However since I'm not very fond of cutting, sanding and polishing manually I've been thinking of buying either a random orbital sander (I feel this is too big) or a dremel for these small fixes.

I like the dremel it seems very versatile and perfect for small jobs but I can't find too many pple using it to repair windsurf boards and neither can I find fine sanding discs (800-1500grit) for polishing...or do I need to use polishing discs?

Thanks

Hi There

I think that for most repairs the dremel is probably too small to use as your primary tool. I think If I had to pick one tool it would be an angle grinder with sanding disc. This is very useful in exposing the extent of the damage and preparing for repair. However, I also use 2 electric sanders (one medium and one small) mostly for sanding (smoothing) the finished repair.

I own a dremel and agree that it is very versatile, I just have not found myself using it much during board repair.

I have angle, orbital, 8 ", 4" square, one shaped like a iron, probably several more.

I have a Dremel that I use a lot, I install boxes , it has a variety of usefull tools, look at the selections available. It's not good as a sander for large areas, I would get a palm sander that takes precut sheets, like 5 X 5, NOT a orbital one.
2nd choice is the one that looks like the iron, it will get into smaller places.

A assortment of sandpaper grit 80, 100, 150, and wet paper 320 , done by hand, will help speed things up

More tools, more fun.
But a Dremel is probably used less than 15% of the time on board repairs, as experience has you using less of a messy glob to grind off.
Sanding blocks of different sizes, multiple grits from 40, 80, and 120 is plenty sufficient, with one small, low vibration...expensive, orbital.

My favorite repair tool is prevention. I don't remember dinging any of my boards even once since I began padding the usual impact spots 20 years go. It takes MUCH less time than a repair, keeps the core dry, and done right, it looks good, works great, and feels good underfoot.

Ryobi multitool is amazing. It does everything and isn't expensive

Belt sander, with finesse, followed by a sponge/disk on a cordless, again with finesse.
Then handwork to finish, for your basic dings, no need to get exotic, but you gotta know your sand paper from your wet and dry.

U2U2U2 why do you recommend the palm sander and not the orbital one? While I do like the fact that I can use normal sandpaper with it. I hear the palm sander leaves scratches.

I do have an angle grinder but that seems too heavy and violent to use on my board.

Isobars - I just picked up a northshore nose protector and waiting for it to be delivered

The most cumbersome work I see is sanding off the epoxy to make it blend with the board. I can handle removing damaged bits with a blade and wet sanding with hand.

They will surely work (at least on the nose), but they are ugly and don't protect the other usual damage spots.

I have a palm orbital sander, to clarify it makes orbits , not circles, it's pretty high speed and no variable speed, it removes quickly , but the control of removal is not good, it does leave scratches from its speed, variable speed would help.

The small palm one I have is a Makita , it takes 4.5 X 5.5 size, buy or cut your own, it's one speed and goes fore and back, obvious will take different grit.
The paper is held on with a clip on each side. Overall operation is great. I also have basically the same thing, but the sanding area, is more like 4.5 X 8,
It's adjustable, works better with 2 hands.
You may find for infrequent use , a drill with the pad to stick paper on, control will not be good, it's floppy.
When I'm working on a board I line them up, and use the one that makes the most sense.
I use the Dremel but it's mostly not sanding, one of the attachments is a flap of sandpaper, it's about 1 inch across, the paper is in flaps , you use the edges,
It removes , like bumps of epoxy, it's controllable, Dremel is adjustable, but limited in area, and you need something to flatten, smooth out.
