My flying gantry machine

[progomez]

havent been using this for a while and now have started purchasing parts for a "better" version.
I have decided to build another to try and rectify the main problem I found when using it which was :

1. Speed/ the m8 threaded rod was too slow (although not bad for the price. i have purchased 3 10x2 delrin nuts off ebay for £9.99. This should nearly double the speed.

Also Im thinking of buying this kit http://cgi.ebay.co.uk/linear-bearing...3286.m63.l1177

Any reason why not. it seems cheap and combined with some trapezoidal leadscrews from merchant dice it should only cost me around £120 for a 1000x700x300 linear bearing machine which should cut 3'x2' peices easily. Can anyone see a problem with the kit? seems cheap.

I also bought a new router a while ago kw800k b&d , off ebay, which will replace the cheap one which eventually burned out.

Im also thinking of what to do to minimise the noise.

Dont do it... the unsupported rail over a 1000mm length will flex badly. You need supported rail for the main 1000mm run and ideally for the 700mm one too.
