    Plastic tubing substitute for vee belts

    Many years ago I bought some round hollow plastic tubing designed to be used as a vee belt. You cut it to length and joined it with a steel internal joiner which you pushed into each end of the tube. It was a "get you home" job really when a fan belt broke on a vehicle/machine but they would actually last for quite some time.

    I am now overhauling my power hacksaw and there are 2 vee belts on it, one to dive the saw blade and one to drive the suds pump. The problem is that both belts are driven off the same electric motor shaft (using a double pulley) and while there is the usual adjustment on the motor it means that it will adjust both belts at the same time, i.e. I can't adjust the belts individually. The saw blade belt is much thicker and longer than the suds belt and so I thought, because the suds pump doesn't take much driving, that I would buy the correct belt for the saw blade and use some of the round hollow plastic tubing type of belt for the suds because I can cut that to length and therefore make it as tight or as slack as I wanted to.

    I have grabbed a couple of images to show what I am talking about. saw2.JPGsaw1.JPG

    I have Googled/eBay'd for it but thought I would ask a question on here to see if there is a "recognised" manufacturer for this type of material these days.

    TIA for any advice/help.

    To be honest you are making things hard for yourself. I would suggest using the adjustment to tension the main drive belt then fit a slightly loose belt to the suds pump and visit the nearest scrap car collection for a timing belt tensioning pulley and mount it to tension the suds pump belt.

    Thank you for that but the saw only gets occasional use nowadays and 60 years ago I always had a length of the tubular stuff and it got me out of trouble more than once. Very useful if you've got some kind of shaft on the front of the crank pulley to drive a pump of some sort because then you don't have to mess about undoing the shaft.

    Thanks Peter. And you're right. The 3rd one on your list is what I'm after. Thank you. Now a little story. Sometime in the late 60s-early 70s our postman had a fan belt let go and he came and asked if I could 'phone his yard so that someone could come and help him (no mobiles in those days !) So I went and got a piece of the tubing and a fastener and fixed him up. A few months later (literally) he rolled up one morning with the makeshift belt in his hand and said that his van had just been serviced and a new fan belt had been fitted and that he thought he should return what I had put on for him.

    The "get-you-home" that I had fitted, on a post van ! had lasted that long. I was very impressed and it will do for my old hacksaw I'm sure.
