    Default Band clamps as an alternative sash clamps

    Hi there,
    I’m in the planning stages of making a dining table approx. 2200 x 1100.
    I plan to use dowels to join the legs to the rails and can get some clamps with the 1100mm capacity to clamp the shorter legs/rails but when it comes to gluing and clamping the longer legs/ rails I will need sash clamps or pipe clamps with an opening capacity of over 2 metres.
    I can’t justify the expense (right now &#128521 so was thinking about band clamps. Ive seen one advertised for $ 60 and seems like it may do the job.
    Does anyone have any advice/opinions/experience with these?
    Thanks

    I think Band clamps wont be good enough. It'll be a pain of a way, may even fail .

    Clamping up dowel joints , specially in tables bringing the two ends together requires direct intense pressure that also needs to be finely adjusted quickly to counter the pain in the backside way that dowel jointing behaves when gluing up .
    Getting everything square and plumb and the final pressure needed to overcome the glue holding the joint open is usually a rush job for two guys that only just works with good clamps on long tables.

    Mortise and tenon . And pegging the tenon is so much better. One clamp does the job for starters. Or Draw Bore it and no clamps.

    One inventive way of getting around your problem may be to glue up the long sides of the table one at a time lying flat on the ground with a longer piece of wood and a glued stop at each end and some type of wooden wedge system . When they are dry bring the two long sides together glueing up the short rails with your shorter clamps.

    Since you're only at the planning stage then I too would opt for M&T with draw bores. But if you don't have the capacity to do that then, as auscab noted, glue it up in stages.

    Also, you don't need clamps that are 2m long. Do you have any, good, quick grip clamps that can be turned from a compression clamp to an spreader clamp?

    Are ratchet straps, as used on trucks and trailers, an option. Don't go for the cheap ones, they stretch and loosen, particularly if they get wet.

    I used these on a queen bed project. About $20 per clamp at Mcjings plus the bits of wood of course.

    Thanks for the responses everyone.
    Auscab, I especially appreciate the advice on dowel jointing. I’ve achieved mixed results before, but only on smaller projects and I take your point on alignment in final glue up. This table is by far my most ambitious project to date. Youve got me thinking about M and T joints now. I’m totally underequipped and under skilled and but hey… I’ll give them a go.
    Also , Feckit I do have quick grip clamps - what is your idea for quick grip clamps as a spreader clamp? Placed at the foot end of the legs??

    It's exactly the same principle as orraloon posted.

    You've just got to make sure one end cant move and the other has something you can use to generate compression.

    Another option is to make some clamp extenders.
