Dog with bone?

Ok... so where do I buy a long belt from? the distance between screws is approx (i need to measure) 1.1 meters. So assuming im looking at 'Pitch Length' I need one approximately 2.2 metres?

maxium i can find is about 1.8 metres (1870mm)

im not bothered what 'pitch' it is etc, so long as its a timing belt. once ive found one il buy pulleys to suite, then bolt my existing stepper drive pulley to the ballscrew pulley (ala jazz)

If you go to any decent bearing and belt supplier you can have belts made to any length you want, thats what I did. Cost be about £15+vat if I remember correct.

Why can't you use open belt? the gantry has to be fixed to one side of it any way?

[Swarfing]

Sorry just re read and you want the belt to cross the screws. Give ERIKS in Swindon a call

The do belts of any size within reason and i found them to be the cheapest at the time.

had one of them nights tonight... first off dropped the ballscrew and bent the end



so, decided to fire up the big heavy green machine in the corner. I should perhaps at this point explain that the machine is jinxed. Every single time I use it, it ends up either hurting me, or my wallet

so spun it up.. the other end whipped round like a b*stard, I grabbed the ballscrew before it killed the dog and...



thats the tidy version... (all those bearings went everywhere... for a moment, it was like a scene from home-alone)


so, after a few beers of contemplation, and a motivational chat with jonathon on skype I formulated a plan...




better. Not quite jonathon standard of engineering, I agree but much straighter.

So being an 'engineer' :D now. I decided to use this useful bit of kit too bore the holes in my pulleys



decided to come up and finish my beer in the house before I broke anything else

i'm sorry but this has had me pretty much pissing myself everytime i read it... i just cant keep a straight face when i read over it and i think i've done so 5 times now..

i'm such a bad person.. and whats funny... i know damn right i'm gonna lose them balls one day

Last time i bent my end and slung my balls out she gave me such a slap
