Hello all! I've gotten quite interested in sanding lately, as i am repainting a lot of skirting boards and doorframes. Sanding is a great way to remove old paint, smooth out the wood, and prepare the surface for a new coat of paint. I find it many times more efficient than using paint stripper.

To that end, i have purchased a powerful belt sander, which i have put to great use smoothing out plaster walls. It works wonders for any large, flat area. it strictly uses sanding belts of course

I also have a detail sander i've inherited, but never used. Its at least 15 years old, i cant find the exact model, its a "Power performance 180w detail sander", and it looks like this:

It has hook and loop attachment for these curved triangular plates, a very odd design. This thing seems to be in perfect working order.

But some of my door frames have odd curves and contours that i am struggling with. The belt sander isn't much use here, the detail sander might be, but its still far from ideal. What i really need is something like the ones here:

One of those pads that sticks out and then has a curved bowl carved into it, would be perfect for my needs. The above is just one random example, i haven't chosen a particular product, ive looked at many

However, my experience with such things is nil, and my budget is pretty low, i'm afraid to just buy stuff and experiment with it, i need some advice here.
A lot of the curved sanding blocks i can find like this are designed for hand use, i do not want that. Hand sanding is strenuous and awful, i find using power tools to be about 60x faster (I timed it on a few test patches!), and i have a lot of these door frames to do.

Some of the curved sanding things i find seem to have a hook and loop interface, but its not clear on which side. It'd be nice if they had that backing, so that i could attach them onto my detail sander, is such a thing possible?

But even if its those cases, what about the actual abrasive surface? I have a large roll of P40 sanding cloth i've been using for a hand sanding pad, it'd be nice if i could use some of that, but if i need to buy special velcro backed sanding roll, i could probably swing it. But its not clear how such things would attach onto a curved pad and hold the shape

What I ideally want is to get an attachment shaped exactly like this: To attach it onto my detail sander
And then to somehow put sanding cloth on it

Is this process possible? What exactly will i need to purchase to accomplish it?
 
I don't think it will work, the sander would need to move in a pattern which matches your detail or contour.
Hand sanding I'm afraid, but it's not that much work. Don't feel you need to take it back to bare wood, you just need to remove the top surface sheen of the old paint, and areas where the paint has built up.

Scotchbrite sanding pads are good for this, use the correct grades in the correct order. Some people get frustrated with sanding because they try and remove an entire paint layer with 320 grit paper, and then wonder why they've got a sore arm.

But it's not supposed to be fun, it is a chore.
 
Buy the American one off Amazon is not a problem.
There is a UK supplier as well.

For walls you really need a 150mm orbital sander or bigger. Mirka and festool sell but other machines available.
Cheap one here reviewed on 10 minute workshop on YouTube.

Also you need to be using mesh sanding for drywall linked to a vacuum as the dust is very bad for your lungs.
Buy a cheap shop vac and make yourself a cyclone to collect the dust and keep the vacuum at max suction.
Information on how online.

You can make fittings but this company is very good. The fitting has an air hole so that keeps air flowing through pipe to stop vacuum overheating.

You can buy Pro kit however you can Knock something up on the cheap

To answer.
I've got curve mirka pad for coving I put on my festool rts400 sander.

Don't worry about this, I have a respirator mask, goggles, and ear protectors, i put them all on whenever i use the belt sander. Safety is important! and its plenty good enough for walls, no complaints there

its just not precise enough for the details on doorframes
 
I do have a Festool linear sander (LS130). AFAIK it was discontinued a couple of years ago.

It had various profiles available to buy off the shelf, additionally, you could create your own profiles. You would glue a strip of adhesive to the timber profile and run the sander until it cut away the base to the reverse profile. You then glue velcro to the underside to accept the velcro backed adhesives.

In principle, it was a genius concept, in reality it was £500 of not much faster than hand sanding (the dust extraction was superior though). From memory Porter and Cable released a "toy" version years before.

As a linear sander, the base plate went backwards and forwards. You are hoping to use a delta sander. Sorry, even with a suitable profiled base, it won't work. Your sander will have a 2 or 3mm orbit. Rather than going back and forward, it will go left/right/up/down.

I have no idea how bad your woodwork is. My advice, given your budget, would be to wrap sanding paper around profiles of timber. I occasionally glue sandpaper to bits of dowling or aluminium strips.

Sorry, not what you want to hear, but ultimately, you are going to have to use a degree of elbow grease.

This doesnt seem right, sure a belt sander turns in one direction, but the detail sander doesn't. It just sort of jiggles and vibrates around. Why wouldn't that be good for an attachment too?

Because it jiggles and vibrates around. You'll be sanding the high spots of the timber flat whilst not touching the intricate bits.
Detail sanders are for getting into corners, flat corners.

Anyway, the answer you seek is above. £500 on a Festool. A cheaper option is wire wool.
