    Default tslot sizing

    G'day guys ,
    It's now time for me to purchase a clamping kit for my mill.
    I'm unsure of what size to get. I saw a spec online for what appeared to be my exact machine and 14mm was quoted, but I want to be sure.

    Ok so I measured my T slots and this attached drawing shows the approx measurements.

    Is this the kit for me (14mm) ? ... https://www.machineryhouse.com.au/C0965

    I remember when I bought my mill, the T slot size was very confusing.

    The T slot size goes by the thread size. So a 16mm slot size would accommodate an M14 size stud. Therefore I believe a m14 T slot is you correct choice.

    I would agree (M14).
    This M14 kit from Magpro actually states its for 15.8mm slots.

    Are they supposed to be a close fit ?
    My slots vary a little but are around 16.2 or 3 wide.

    They should have a little wiggle room, that way can slide them along easily.
    A little swarf will soon stop them sliding.

    I made some up that you don't need to slide in from the end, you just drop them in and twist. Very handy if you have a setup and need an extra clamp etc, this way you don't have to break the setup down to add it into the T slot.

    I can get pictures if you are interested, it's a neat little machining project.

    Also keep an eye out for the same thread as the studs in thread rod, then you can make extra/longer studs which come in handy.

    I was just going through a lot of the stuff they sell.
    Some pretty good prices there.
    Have you bought from them before ? if so, what are they like to deal with ?

    I've bought from them and been happy with the quality and service. They are about 10mins from my work so I've never had anything shipped.

    I'm about due for another visit.

    Thanks Dave, so simple, I'm amazed that the Chinese haven't started producing them.

    They are not as high strength like the standard T nut because they only grab 1/2 the normal contact each side, but are plenty strong enough and come in handy without the need of breaking down setups as I said earlier.

    Or like me sometimes your to lazy to clean out the T slots after working all day and want something set up quickly to finish a job, lol

    Just for anyone following that don't understand them.

    Place a stud in them ( they have 4 punch marks underneath near the bottom thread edge to stop the the stud screwing though the T nut)
    They drop from the top through your standard T slot, then with a twist they lock into your T slot. When tightening they are forced under the T slot.
    To remove just turn backwoods anticlockwise till they line up and then remove them.

    If you making T nuts or your new ones don't come with punch marks, put them in to stop the stud jacking your table T slots and breaking them out when tightening them up.
