Cutting tap holes in Acryllic Baths

There was a post on this very recently.
Search "acrylic" (one l) and you should find everything you need to know.
PS - hammer and chisel suggestion was a joke (I think....)

 

I usually pilot drill with a hss bit, then use an appropriate hole saw Paul. Always nerve wracking the first time

Put some masking tape in the area, Mark centre line of bath and measure 90 mm either side of this as taps usually at 180 centres. Using a square, draw lines through these marks. Offer your taps up and make sure that they overhang sufficiently. You can then make a pencil mark of the pipe centre. Take an engineers square or measuring tape and transfer to your tap centre lines. Double check that the fixing nuts underneath won't fowl on any radius of the bath. Good luck

 

Hammer and chisel is the best i found. Preferably a sledge hammer!

 

Measure twice & check centres, easy to get it wrong

See this thread for tales of woes, cocking up!

Ya evil sod, don't think he will ever make that mistake again.

 

Yes and make sure you leave enough room for the much bigger fixing nut underneath, i.e. don't let it foul a bend in the bath lip/edge.

 

Use a 32mm hole saw, or even a flat bit will do the job so you have a couple of mill play when eyeing it up.

 

Personally wouldn't use a flat bit, they can wander and vibrate. deffo a hole cutter for me!

 

Yep, a hole saw is definitely preferable, but, the hole size doesn't need to be precise and a sharp flat bit is more than capable for the job.....
Smells better, too.

 

Love the smell of cut fibre-glass in the morning

 

Get a decent hole cutter like a Starret not a cheap and nasty one.

 

Probably got a Cromwell branch nearby.

Are 'Starret' still as good as they used to be?
I acquired a used set over twenty years ago, that's still razor sharp now after many cut's in different materials, just wondering if the quality still remains?
Bought a few of the 'Bosh' progressor quick change hole saws a while back, and although the quick change is fantastic.... the cutting speed is a disappointment, the old starrets are soooo much better.
Are they still good quality?

 

Got no problems here with Starret,drilled some 25mm holes through 8mm thick flat steel bar last year, hole saw still got life left in it.

 

Were they recently bought, new ones?
I used some from my old set recently for drilling 20mm holes in 6 mill rsj's, no probs!
If so it's starret, from now on!
The Bosh one are mediocre in comparison.

 

Bought December 2015.

 

That's good to know.
So many brands seem too lack consistency in quality across their range of products, can always rely on starret.....
Champion.
