here some data from the ‘front’ :
we came in 2 months ago with already the minimum equipment and a good bag filled with experience to make the machines but also being able to make research and new machines. the minimum equipment is a top notch welder (fronius transsteel 2220 3500 Euro tig/mig), a 2 Tonne lathe with updates and tooling = 2500 Euro, a DIY CNC mill, able to cut steel = 3000 Euro, metal band saw 500 Euro, 2 second hand drill presses (small, and heavy duty) = 800 Euro and endless of power and hand tools for another 1000 Euro (that stuff dies fast). Absolute needed entry stuff, there are no corners one can cut here
Apart from the welder that are second hand prices.
With our MVP (minimum viable product) we’ve done well and earned around 1500 Euro the first month then later on we’ve sold a few shredders with extrusions and increased it all to 2400 Euro in total for 2 people and seems stable now (not increasing). Most of it goes back to the shop and research…
We are working full-time, 50% production and 25% research and 25% of volunteer work (PP and others) but I hope to increase production efficiency to spent more time on research…
After 2 months, we’ve figured we need more machines being able to make better PP machines : DIY plasma cutter = 5000 Euro, surface grinder = 2000 Euro, mill (with indexer, rotary, CNC update) = 8000 Euro (one 5K is ok too) and some tools to do quality testing = 1000 Euro, a paint room (powder coding) = 1500 Euro. As you see, this can’t be bought all together. It takes an entire year (or 2) to get that things. However, with every new machine one can extend the portfolio for new products (machines) and so may be things get faster…
Cash flow with the bazar is quite a big problem (we managed). One receives only the money after the first thing got marked complete. It can take many weeks til you receive the money. Til then you have to invest in not only the machines but also the material for the products, it’s then near 10 000 Euro. Rent not included …
After watching this for a while, I would say the best kick off is around 20000 – 30000 Euro to start a shop and do good products (still minimal, not looking really mature… we still feel bad to sell a 2000 Euro shredder when looking at what it is, there is sooooooo much todo to make those PP machines right)
btw, invoicing those machines makes it entirely NOT possible: you have to add income tax, VAT and so the machines go out for the double of the price = 1% of our customers can effort that. So to have normal life with building PP machines you have to be extraordinary good and work really hard.
