cutting fibreglass with tile saw
jabbahutt - 30/3/07 at 12:22 PM

I've just bought a tilesaw at dinner time ready to start on my fibreglass body panels this weekend.
I understand that you should cover the area to cut/drill with masking tape but can you use the saw in both directions or only away from the gelcoat finish side as you supposedly are meant to when using a file

Thanks for any help

Both directions should be ok with the tile saw, although if you wanted a really neat edge you could finish off with a dremmel.

Trial cut a piece of fibreglass first with the tile saw and see if it gives you the result you want.

Edited to add: Don't forget to wear a mask whilst cutting.

I just used a Jigsaw with an Aluminium blade, and masked off areas where I didn't want chipping and left areas that I didn't care about - but it still didn't chip there either!

about using a dremmel I have one and I'am not sure which attachments to use.

Can anyone elaborate on tools to use with fibreglass. I have the ones that look like brown cutting discs and small rolls of sandpaper etc but wouldn't want to go near it without knowing which ones are suitable.

Thanks for the help and hopefully everything should go okay this weekend.

I'd love to test on a piece of fibreglass before starting but unfortunately only have the panels to practice on!!

Well your panels should give you a bit spare somewhere???

Either way, for finishing of the panel (after cutting with jigsaw/file/tile saw etc) would prob be best achieved using the small sanding drum attachment.

If you use a reciprocating saw (jigsaw, Cengar etc) then make sure you clamp the panel down well to avoid it flapping. Hacksaw blades work well on fibreglass. tile cutters don't give a crisp egde, so it will need to be cleaned up afterwards. The best tool is a 'cut-off tool'. A small diamond tipped blade angle grinder type thing (usually air-powered). they are great for cutting long cuts, but not so good for fine details. That is where the Dremmel comes in very handy....

watch as cutting tools can get red hot cutting fiberglass because of the friction, best to take it slowly.

I use normaly a cutting disk on the grider and a flapper wheel for finishing but it does produce a lot of dust.

With a dremmel i used a large (2cm) sanding drum. The larger the better as it will give you a smoother radius.

Obviously rough it out with a drill/hole saw first. Some cuts/holes i just used the hole saw its self, mask it off first.

These are awesome...



Dremel Tilesaw (562)

Very smooth, no vibration and last ages. Perfect for rear arche light holes and alsorts in fibreglass.

For cutting edges etc, I can't recommend a diamond cutting wheel high enough... Rescued attachment normal_ZetecClutch_016.jpg

Above hole was made by using a hole cutter for the corners and the rest was a diamond wheel....this is after the raw cut - no sanding or filing work has taken place
