You need to wear a dust mask AND if high speed cutting avoid creating fumes as they are listed as toxic.
I've been cutting it for years. A vacuum cleaner is a bonus

Kort hatch mock up. Imagine deck all painted same colour/finish as below water line and hatches secured with unpainted stainless socket screws flush. Just enough space for Gog iron betwixt.
Deck 3mm ply
Kort hatches 3mm paxolin
Kort hatch shelves 6mm paxolin affixed with resin, drilled and tapped for hatch screws

10mm wide by 3mm self adhesive felt arrived from ebay Germany. Felt is cheap but postage is not.
I'm very happy with the quality and would buy again

So I found out after breathing it in most of the afternoon, my lungs aren't too happy this evening hopefully that is mainly the man flu not the Paxolin

I actually like the smell, for me its nostalgic
I cut strips with a TCT metal cutting circular saw. I cut profiles with a Jigsaw with wood cutting blade.
Good sharp files are a must.
Any medium abrasive will do for pre gluing

Bakelite had gone out of production 10 years before I was born

it's quite a useful material which can be used for many things

but as for the smell!! nah it's worse than Old Spice after shave

I've yet to experiment with paint on it

Paul2407 · « **Reply #284 on:** April 12, 2017, 09:09:17 pm »

I should think it would take paint fine as long as the surface is given a key or maybe using etching primer first

Thanks for your posts
Firstly I'm just reporting my findings as I go warts and all but not intending to belittle MMM. They provide a valuable service as a whole and many people have bought multiple models.

I've decided not to proceed yet with the running gear as to tank test it would mean fitting the stern tube extensions. These are now much more difficult to remove and if you slip you risk knocking your Korts off !! there's no room for error.
The previous threaded design was IMHO better but more expensive to produce.
So I'll continue with the hull to the point that it is fully primed and laquered below the waterline then I can fit the Korts permanently

Looking back in review. Re the Eze extensions I have found by necessity that it is better to remove them if the need arises by using a good thick piece of rubber to protect the paint and a pair of pliers. It was a relief that this worked rather than MMM's method statement

Ok I'm away but it doesn't stop me thinking "boats"

Other questions for the Guru's

What filler is effective on styrene sheet? The bow bulwark needs padding out a bit once the deck is on so Ideally I want something that will do from 5mm max down to a feather edge.

What is the best type of primer for styrene

Most suitable product to stick the bulwark ribs? styrene
/wood and can I glue to sanded sanding sealer? I would like to fully fill all deck grain before fixing ribs.
Alternatively would I be better using sanded finishing resin and glue to that?

Thank you kindly

HI Tc33cno no with out a doubt Halfords car acrylic primers for styrene and glass fibre hulls. primers come in the following red, grey, white, they can have enamels or acrylic paints applied over them. Not sure about the fillers At 5 mm deep. hope this helps.
