    Default Trouble with springs

    Dear all,

    Having bought some more grinding equipment I ran out of money for the adjustable tool rests that are very beneficial when grinding. What I'm referring to are the ones that are sold by CarbaTec, timbecon etc that have the levers that are spring loaded. I own one of these jigs and am impressed with how easily adjustable they are. I really need at least a couple more though. They look simple to make except for that spring loaded lever part. I guess I could use a wing nut but would love to create the lever as on the commercial jigs. Could someone please explain how these spring loaded jigs work and could they be created in the workshop? I notice that few people use springs in their jigs, is that because they are difficult to use or source? Any advice is appreciated.

    Tiger,

    I'm guessing you are talking about the screw levers that have a spring to keep them engaged, then once they are tightened you can push them and spin them freely?

    Try the LeeValley cam clamps http://www.leevalley.com/wood/page.a...,43455&p=45034, they are not the same, but work beautifully, and will cost a bit more than $6.00 each landed in Oz.

    or maybe the www.woodpeckers.com.au guys could help?

    Cheers,

    P

    Hi Derek and Midge,

    I have taken my $40 grinder rest apart to see how it is constructed. The spring sits on top of a socket screw which engages the lever as Midge has stated. On closer examination the spring is really not that vital to the overall functioning but I do like the lever action in quickly adjusting the angles of the tool rest. I now will try and build a tool rest which is adjustable. I could do it with a bolt and a wingnut but the lever is a nice feature of the commercial jigs. I do a bit of turning and the adjustability helps with all the different turning tools so I'm wondering has anyone got a plan for an adjustable tool rest? Why these are not standard features on grinders instead of those ****** rests they have has got be beat.

    If you did a crawl thru the engineering parts suppliers you might find them as a part.
    Farnell had them in a variety of sizes at one time.
    They are a bolt with the finky springy bit fitted to the top.
    They are all over lots of serious machinery, blackwoods perhaps.
    Or maybe the bearing suppliers.
    cheers

    Most powertools have sharp teeth.
    People are made of meat.
    Abrasives can be just as dangerous as a blade.....and 10 times more painfull.

    The part is sometimes referred to as an adjustable locking knob with a spring-loaded handle. I like the fact that they can be used in tight spaces as you might be confronted with when working with a grinder.
