threading ground bar ends

Bright mild steel would give a few thou clearance in nominal size bearings; if you need better you could use ground stock. Both these have the advantage that they are machinable where linear bar might well be hardened and much more difficult to machine.

Ive not seen any request for a price on this.
Sorry, this is not something we are interested in doing.

Not sure how we missed this one.
The reason why we dont want to do this is because the M24 thread will still be within the hardness (Partially) so annealing will need to be done.
This may also cause the shaft to bend slightly?

Hi Deisel, do you have a build thread for your injection moulder? Are you building from any plans or are you just working it out from the machine in the video?

i havent bought the rail yet case theres alternatives its for a shed injection moulder i just need to complete the top half assembley and planned on useing flanged bearings,it will be very simular to the one in the link but i cant make out how they have fixed the ends of the rail to the plate top and bottom so my plan is to screw the rail into the large bed plate at the bottom and use nuts top and bottom of the top plate.

yeah i wanted linear rail because its pretty much garanteed to be straight,id need to cherry pick anything else and thats not an option with buying on line,theres a place local i maybe able to get the threading done i'll see what they say monday.thanks all


gav no plans,but i may get a log going once i get a few more bits in ;)

I couldn't watch this video. No safety guard, hand in closing machinery. Bloody OUCH! Time off work, then back to a job that only needs 1 hand. AND don't think it is safe because it has a spring loaded self return gizmo, they can stick and jam. If your hand is there it becomes raspberry jam.

Get a Grip Man because the guy in the Video Holding the hydrolic lever has.! . . . . He'd have to fall asleep to get is hand trapped in that it's so slow.

found a place to do the threading,cheers

Some folk are slow enough to get caught in machinery, no matter how slow it's moving ;-)
