  13. There was a company a few years ago (big blu?) that was making these machines comercially. they, by memory where using a bottle jack instead of the strut and star nut arrangement for adjusting the bottom roller. this might be something else worth considering?
  14. g'day all, how well do gas ht ovens with the sacraficial pipe hold set temp? do you need a gas solenoid linked to a thermocouple to really hold set temp well or can you achieve this just by adjusting the burners? thanks.
  15. G'day Geoff, have you seen this design? http://www.riversidemachine.net/productCat4985.ctlg sorry,dontknow how to make the link active. i like this design because all the hydraulics are underneath and guarded, rather than at head height should something go wrong i started a similar thread myself a while back, i cant remember if it was on this forum or bladeforums.com, there are more pics of the same design on that thread. i'll see if i can find it for you. have a good new year mate and post some pics of your progress The thread is on this forum, but i cant seem to link to it. if yo
