    Default Workbench Beginings

    Hi All,

    I'm looking to start off a redesign of what I want for a workbench as I had issues with my first attempt, mainly aroundold twisted timber that didn't join well for my workbench frame. So here goes.

    Purpose: As per the forum name, this will mainly be a woodworking bench , but will also be used as a workspace for car maitenance as well as various electronics projects when time permits.

    Restrictions: Due to space the left hand side and the back will be against a solid wall. It can be a maximum of 1700mm wide, depth is flexible. I also have to be able to build it with minimal hand tools (saws, plane, chisels, squares)

    The Plan:
    Workbench top - 1700x800x50 probably MDF with a masonite cover
    Workbench frame - basic six leg frame made of 2x4 with a bottom shelf as that's the easiest way I know of to make it rigid
    Vice - Basic Righthand side vice

    So with this in mind I had a few questions
    1. Would you recomend mortice and tenon joints for the frame?
    2. Should the frame be made flush with the front and side edges of the benchtop or should the benchtop hang over the frame?
    3. The dog holes (I think thats what they are called) on the benchtop, how to you work out the number, size and spacing of them?
    4. Would routing out (I can borrow one) a groove for the frame be good enough for mounting the benchtop?
    5. I'm taller than average 196cm, so how do you work out the best bench height? any general rules

    I'm hoping to finish this design in the next two weeks, so any help on these questions or any other aspects of the build would be appreciated.
    I'll try and get a sketchup image of what I am thinking today or tomorrow.

    Cheers
    Dave

    Welcome Mr Big.
    I would make a solid woodworking bench with an additional removable top that can be used for the other pursuits. Stop the diff dings or oil spills.
    The dog holes should be spaced slightly less than the maximum opening/ adjustment of your movable jaw/dog/clamp.
    The bench I'm building has the legs flush with the front face of the top (link in sig) and uses mortise and tennon joints but do a search on bench builds and have a read of some old threads. Theres a wealth of information on this site.
    There is some good information on bench height in here
    Those were the droids I was looking for.

    OK so after having a look around at many other bench designs, I've had a rethink of what my bench will end up looking like. For te frame I thinking of going with a torsion box style frame as this seems to be a little bit more forgiving in terms of assemby and accuracy and proabably a better proposition as I don't have a workbench to use when building my workbench. The other benefit here is that it will effectively be a knockdown design so I can mvoe the bench if I every need to.

    The other chang I'm making is that the bench will be going on castors as realistically assessing my location having something I can move into the middle of my garage for use will be much more functional than something stuck over in the corner.

    I've attached a quick sketchup model Of what I basically think the bench will look like to give you an idea of what I had in mind. The main overhang is where I would mount face vice.

    Hey mate,

    Have a look at Christopher Schwarz book "workbenches- from design and theory to construction". I just started reading it and it's excellent! Highly recommended. He covers some of the questions you've asked and a lot more.

    Thanks for the feedback so far, and it looks like I have two issues to sort out.

    1. How to move the bench - this bench will sit in the corner of my garage and I would like to be able to move my car and put it in the middle when I am working, although perhapsI can live with the corner for most tasks. Lockable castors seem to not live up to their expectations especially for hand planning based on comments on the forum

    2. clamping for working on all sides of a board or piece of work - I believe I can do this with only a single vice on the left of the workbench as long as I add a sliding deadman to the front and ensure that the legs are flush with the edge of the bench. I think I have this one covered, and I'll try to work it into the sketchup model soon.

    So any thoughs on the first point would be appreciated.

    Thanks
    Dave

    Well i've finally made my decisions and started work on the bench. 8lengths of 2.4m structural pine and 4 threaded rods and I can make a start.

    Facing the problem of needing a bench to build a bench to build a bench i've made use of my sister in laws old study table that has yet to make the council clean up.

    After a few.short weekend sessions I have some completed frames for the base of the bench. Next step is to glue on some ply sheeting to the frame and assemble the bASE. We'll see how long that takes.

    I.ll post up the completed frame when I get the cAMERA working again.
