    Very good question and something I've been thinking about. There are slots in the motor bracket which will allow me to tension the belt slightly by moving the motor sideways, I will probably have to widen the slot I cut in the top though. I tightened everything down slowly over a few days and it seems okay but I have a feeling the belt is a bit sloppier this evening than it was yesterday so I might have to come up with something else.

    Open to suggestions as always!

    Okay yeah I just tried moving the motor sideways and it didn't make enough of a difference, if the belt gets any looser it's going to be a problem.

    Need to do something else I guess, no idea where to start though really.

    Put the motor on a hinged board that can be raised lowered by a locking bolt.

    This might give you some ideas.
    On my WW lathe the motor is on a metal baseplate that is hinged at the back.
    The All Thread rod is connected to the front of the bench *two bolt heads visible"
    Then a pair of Knurled round nuts above and below the plate determine the position of the plate and hence belt tension.

    Awesome cheers, I should be able to figure that out!

    Hmm I think I can repurpose some of the spare parts for the motor tension bracket.



    Thats a part of the blade tension assembly, the shaft on the right hand side is threaded so I shouldn't have trouble fixing it in place. The whole threaded rod pivots so I'll mount the motor to a hinged board and cut a channel in it for the rod to pass through.

    Popped out at lunch and picked up some stuff to figure out the belt tension this weekend. I'm really glad I remembered about that tensioning rod from the parts machine, it will make life so much easier and should look the part too. Here's a sketch of what I'm planning and pics of the hinges I bought.







    Basically the shaft that goes out the side of the tensioning bolt will pass through a piece of timber and get screwed in place, then the timber block fixed to the shelf. I'll mount the motor above it with the hinges attached to another piece of timber to set the height. The platform the motor is attached to will have a slot cut out for the tensioning bolt to pass through, this will allow the bolt to pivot and tighten down properly.

    Sound good?

    I'd put a nut as shown below otherwise the whole weight of the motor will be on the belt.

    Made some more progress today. The bracket for the threaded rod is all done, just need to figure out the mounting height and position on the shelf. Not 100% on using a spring, I have a number of different sizes to fine tune it but I might just go with a nut and washer as mentioned earlier.





    Had some veneered mdf cutoffs from the place next door to my work (renovations) so I cut that down to size and will glue up later on this evening. Also made a little metal plate for the metal rod to pass through, first time using an angle grinder but I managed not to hurt myself so I'll call it a success.

    Works a treat
    The bandsaw really needs a restoration but it will have to wait.
    I didn't realise how much I needed it till it wasn't there to use.

    Hi Buller and Rick. Was that “spare” Junior located in the ACT by any chance? because I bought mine off Gumtree about then. Tonight I was searching google for an image of the Woodfast junior badge when I came across this thread. Sorry if it’s already be answered because I haven’t read every page yet but how is the belt tensioner working out as I have a few ideas for it and how did you get on with the tyres? I sourced new tyres from America for about $68 delivered for the pair. I couldn’t believe it when I contacted them and not only did they know about the WF Junior but they stocked the tyres for it. I have set mine up in a similar way to yours but I have set it up to cut metal which meant reducing the blade speed from about 3000 feet per minute to 150 FPM so mine has 4 pullies plus a bearing used to tension the belts. I love the way you have restored yours and have decided I really need to do the same to mine. I can post some pics if you are interested? Anyway, well done and cheers. Stuart. Ps the badges on mine are a different colour to yours.

    Hi Buller et al
    No sure if this thread is still being monitored given it's age but...
    Found this entire thread fascinating.
    Have just inherited the same woodfast junior, works like charm with one exception - the thrust bearing - it's stuffed.
    Any advice on how to restore or get some equivalent replacement would be appreciated?

    Hi Bueller
    I had to replace the tyres on my woodfast junior as well. The original ones were leather (atleast I think so - hard to identify because they were so cracked and dry.) I opted for the urethane tyres and i put some 6mm flyscreen spicing in the groove. It created a slight crown in the tyre but from what my woodworking buddies have told me that is what you actually need and the back of the blade gullet runs on the centre of the crown. Seems to be working okay. You also asked about the blade guides, mine doesn"t have a lower guide either. Would love to know how you get on there and with replacing the top guide.
    Cheers
    Cathy
