    Default tablesaw table flatness

    Hello all,
    I am in the throws of purchasing a new tsc-10hb and am having issues with table flatness.The first unit had 1.5mm clearance across the table due to wings not sitting flat. This was checked at 90deg to the blade, at front and back. I thought this was too much for shims. The "skirts" on the wings and table were not square to the tops.
    So I contacted the supplier and saw 2 had .5mm across the table. Could this be shimmed out? Also there is a bow from front to back on the main table which results in a .5 to 1mm gap if I place the straightedge on the table and clamp it at one end with my hand. The crown of the bump is just before the back of the blade at full height, evenly on both sides of the blade. I am using a straight good quality spirit level 1200 long and a steel square. Both are true.
    After reading many posts here on this issue of flatness and shimming I am wondering about tolerances. Any thoughts?
    I want to stick to this model after reading all the relevant posts here( thank you to all you woodies) and doing my own research with torch and kneepads.They are so well built under the hood. I will be using it for fine cabinetwork and with a slider, all the joinery in our house.
    cheers,
    Tony.

    Even the Carbatec equipment is built to a price where some quality control is sacrificed for the bottom line.
    It does look like a pretty nice saw though. The specs are good.
    The only way I know of getting the bow or hump out of the table would be to have it machined flat on a big grinder. It is cast iron after all.
    Probably expensive.
    Getting the wings to line up perfectly with the main table should be achievable though depending on how they are attached.
    Any pics possible ?
    No doubt there are others here with the same saw that may be able to help.

    Hi Tony,

    I had the same problem with Table flatness with my SB12 table saw.....

    See my thread on this and my solution in the Products Review forum. https://www.woodworkforums.com/f171/s...et-saw-148542/

    I had both the table and wings ground flat.

    I now have a perfectly flat table.....And the by product was that the wings now Joined up with the main table.

    Cheers

    Mike

    Thanks Stewie, Mike.
    Stewie; the saw is repacked now so I can't post any pics-the wings are held on by three 8/10 mm bolts with spring washers. I am new on this forum and still need to get a handle on posting pics etc.
    Mike; After reading your thread I do remember coming across it late one evening a few nights ago. Hopefully this will be a last resort as I am off to sort it with the suppliers Monday. It's Carbatec Bris and their response and service have been very good.

    Mike, something I just realised -duh- you are talking thou in your thread. which is the answer I was after to my query-whether or not I was being too fussy with this saw-and it seems I am definitely not.
    Tony.

    Tony...never be UN-fussy

    Being fussy means being deligent at striving for the best. And the best you can get out of your equipment will equate to better (easier) work down the track. Of course never become OCD at the expense of fussy

    Attached pics of my SB12 saw with new re-ground flat top. Now I can put a square up to the blade from either side and its 90 deg....

    Thanks Mike- Quote "Being fussy means being deligent at striving for the best. And the best you can get out of your equipment will equate to better (easier) work down the track. Of course never become OCD at the expense of fussy." Lovely words. OCD ?
    The L plate is great.
    Thanks Stewie D and Acco- I will read those. Coming into this forum is like stepping through a side door into a Working With Wood Show in full flight.

    OCD = Obsessive Compulsive Disorder

    There's a bit of it in all of us

    If it is the same one I bought from Carbetec,nowhere on the set up instructions did it mention about some grub screws i found in the box!!
    The aprons when i screwed them up where way off, dropping down heaps,I didn't bother to measure then thought thats what these screws are for duh!!
    Table top is now as flat as you would want.
    I would guess most units have something similar

    Well! I am back from Carbatec Bris. Nearly did a refund jobbie but after shooting off all over town with my straight edge (leaving the saw at the shop) looking at tops and finding similar I realised to get that combination of heavy build and precision ground top I would need to go to the next level. Back at Carbatec, the TS-12RX was an example and though they offered me a good deal to upgrade, I could not go there. Budget. So I returned home again with my 10hb.
    I have just come down from my workshop, having put the top together. After rechecking the edges and surfaces again I set to work. I don't intend to use the saw as a router table (my router is in a carpeted wooden cabinet to cut noise down) so that wing went over the motor access door and fitted much more flatly. GOOD. I cleaned the paint off the long edge of the second wing and attached that edge to the left hand side of the main table. All bolts nipped up just off tight. Starting at the front end I tightened each bolt as I leveled it with the table using a rubber mallet and 10 inch straight edge. There was a bit of bow down the length of the wings and the table and luckily I was able to put opposites together and bingo. Tapping between bolts as I went leveled out any differences.
    90 deg each side of a new blade and a piece of writing paper can just fit under the 1200 level in the largest gap!!!
    With the bolt holes on the wings-the switch I am moving to the right as I intend to get a slider soon and from the drawings I don't think I will have any issues with the fence rails setup.
    Did I mention the prayers to the god of Cast Iron. Well I should have-there were a few.
    So I am a happier sawdust maker now. Fire her up tomorrow.
    nrb- I found no grub screws nor holes to suit.
    simops-I don't have any obsessive compulsive issues,I just worry about things sensibly.
    Cheers
