Hi David,
Thanks for the post and sorry for the delay in getting back to you. You're like-minded with many other customers both on this forum and that we deal with just through the business; we'd be very pleased to work with you and help you to grow your business (and ours too) by helping wherever we can.
It's tricky to know exactly what to tell you to spend your money on in terms of a start-up and, in many cases, not specialising in the beginning would mean that you would need more equipment and more types of material which pushes the startup costs up. For example, the best materials and equipment for making small details parts (like wing mirror covers) are different from the best materials and equipment for making larger parts (like bonnets). In this example, I would be thinking of pre-preg for the small parts and resin infusion for the larger parts. You can resin infuse small parts and you can pre-preg large ones but the most time and cost effective way to do each of those is those respective techniques.
Also, the standard you want to work to will have an impact. If you want to make completely professional parts you need to expect some hiccups during the learning curve (which will need to paid for!), and some decent equipment. We go pretty over the top in our videos in terms of using the best of everything but even working on a slightly stripped back version of making our carbon fibre bonnet you would be looking at more like £1800 by the time you'd bought the mould materials, all the equipment and the materials for the bonnet.
It might be worth deciding what your first parts will be and focussing on getting the equipment and materials you need for that first product. In this case, £1000 startup is probably perectly realistic. OK, you won't be a fully fledged composites company but if you specialise in a certain type of part then you could get up and running with that to get yourself going and then, as you say, put money back in to grow the business.
3. Would it be worth my while to take a course on CF as I have no experience with it or should I wing it as I have been doing all along!
This is totally up to you. I think everyone on this forum would agree (from doing things the hard way) that money spent on a course would pay for itself in terms of money not spent on wasted material and you move down the learning curve yourself. We sell materials and (now) courses so I can be impartial on it and say it really depends on what you prefer. Our resin infusion course for example is a 1 day course and at the end of it I can say with 100% confidence that you could resin infuse parts to a professional standard without any issues. Learning on a course would certianly be a quicker way to perfect a process such as this but it's by no means the only way.
I hope this helps and look forward to working with you.
All the best, Matt
