Hello, here is my new machine

[Zeeflyboy]

I wouldn't bother upgrading it (certainly not yet).

The spindle on there will be fine for light composites and plastics work - my first machine just had a dremel type router and did a perfectly acceptable job cutting composites like fr4 and carbon fibre, plus did a perfectly respectable job on acetal and other plastics. You are obviously just a little limited in material removal rates due to the relatively small bits you can use.

Ultimately you just have to have realistic expectations from a machine that only cost you a few hundred quid and change. I think in terms of value for money for getting up and running with a machine they are usually fine, and a good entry point to get your toes in the water - you can always move up to a more capable (and consequently more expensive!) machine if you decide this is the path you.
