Which tool

[ripvan1]

would I use for this not possessing a router or dremel?

The cabin floor is foam cored and I want to remove an area of the inner fibreglass coating to get at the foam, remove and replace. Obviously I don't want to go right through to the outer skin so a depth of say 3-4mm max ix only required.

Is there a router bit to fit in a drill that will do this, or would a well worn angle grinder disk do the job

Thanks

Angle grinder and a spacer block?

If you can fix the block to the grinder you can use it against a batten to get a straight cut.

Hire a router - or buy a wee one. you'll not regret it.

Possible?

Bosch 180E - versatile tool, cheaper than the Fein.
The Bosch is my favourite for most of these type jobs - or a Dremel clone?

You can cut out panels and 'stick' them back

You can get thin grinder disks which would do the job easily.

Get them from your local autofactors/hardware shop or

Yep - or better yet (from a budget point of view) the Aldi knockoff of the same tool. Reckoned on uk.d-i-y to be just as good as the Bosch one, but cheaper.

I've used mine for exactly this job, replacing the sodden core of the aft deck.

Not a router bit in a drill: limited control and to sharp to be near digits.

Have a similiar job looming and will be using a fein with abrasive disc cutter or angle grinder with a fine cutting disc, from previous threads I gather metal discs work best.

Good luck with it.

Thanks all, grinder looks favourite for me then but may invest in beginners router as I could find other work for it

Hi Steve...

I am still stuck in Gib. sorting this engine...anyway..1/8" plasma metal cutting disc with a wood spacer block is probably the cheapest option...dont put too much pressure on these thin discs though...they shatter and break up...all the best...Ian.

Have a look at

These guys cut the outer skin off using a hand held circular saw to gain access to the wet balsa core underneath.
Obvoisly you have to experiment to set the cutting depth and suspect it was a tungson carbide tippped blade.
So if you don't want to buy fancy tools and cutting disks etc, thismight be an option

If you're still looking for a router - Aldi were doing some at about £25 the weekend. Was tempted myself but decided the old one from a car boot sale for £2 would keep me going

thanks again for replies, ian, how's the engine going - are you m the move yet? don't quite comprendo what you and another mean by putting block on grinder - ?

You only want to cut through the top skin, not right through the whole panel. I assume they mean somehow clamping a block to the grinder to act as a depth stop.

as prv says....

'You only want to cut through the top skin, not right through the whole panel. I assume they mean somehow clamping a block to the grinder to act as a depth stop'....exactly right...so about an 1" thick block would do it......and ...
yes still stuck in Marina Bay..should get the bits I need by air freight by Thurs or Fri...so hopefully I can get away from here then...

When I took out a rectangle of the inner hull skin on my Sadler to fit the backing pad for yacht legs I cut them with a padsaw. Very easy work and no risk of going too deep. I assume a floor might be more heavily built than the inner topsides but probably not a lot.

 

[nigelmercier]

not possessing a ... dremel?

Buy one, you won't regret it. There are plenty of clones if you can't justify a real one.

Maybe a plasma cutting machine would help? You can get one from here:
