X & Y Sliders method 1 (depricated)

X and Y axis sliders I realy like the Idea of re-using the skate bearings as linear slides as they realy slide well on the 8mm bar. I tried several ideas and ended up with the following design.

Making the sliders out of four pecies of 2" x " actualy its really 44mm x 44mm now.

Here are the pictures of the construction.. :-

X slider build


Materials :-

1 peice 22mm copper pipe 65mm long.
2 peice 22mm copper pipe 35mm long.
2 peice of 44mm x 44mm x 78mm long,
3 Skate bearings.

Tools used:-
Pedestal drill, 22 mm wood bit, 10mm wood bit, 6mm drill, 4mm drill,Pipe cutter, Wood saw and vice.
or
Hand held drill, 22 mm wood bit, 10mm wood bit, 6mm, 4mm drill, drill Pipe cutter, Wood saw and vice.


Method used:-

Note:- You must use a vice or make a little jig to hold the wood blocks not only for safty but to mantain acuracy.

Cut the copper pipe to size. Cut the 44mm x 44mm wood to length mark he center of the longest axis clamp both together and drill a 6mm hole mark all the sides of the joined parts so you can put them together again. Bolt the two parts together now mark the centers of the running bars on the same side. Very carefully drill the two pilot holes I used a 4 mm drill.
Seperate the two pices of wood then carefully drill from the inside face of each the two 22mm holes in each piece stopping to leave 4mm thick wood at the bottom of the each deep hole. Now from the other side of each hole drill a 10mm hole.


The blocks are finished push 1 skate bearing into the first hole on each block and pop the long pice of pipe in one side. Put the two pieces of short copper pipe in the other holes with the third bearing in the one side push together both parts slide the bars in both holes when assembly slides bolt the two parts together.

Time taken:-
Around 40 minuets or less.

Y slider build


Materials :-


2 peice 22mm copper pipe 31mm long.
2 peice of 44mm x 44mm x 50mm long,
4 Skate bearings.

Tools used:-
Pedestal drill, 22 mm wood bit, 10mm wood bit, 6mm drill, 4mm drill, Pipe cutter, Wood saw and vice.
or
Hand held drill, 22 mm wood bit, 10mm wood bit, 6mm drill, 4mm drill, Pipe cutter, Wood saw and vice.

Cut the copper pipe to size. Cut the 44mm x 44mm wood to length mark he center of the longest side clamp both together and drill a 6mm that is 15mm from one end. Very carefully drill the pilot holes I used a 4 mm drill now carefuly drill the two 22mm holes in each piece stopping to leave 4mm thick wood at the bottom of the each hole. Now from the other side of each hole drill a 10mm hole.


The blocks are finished push 1 skate bearing into the hole on each block followed by the 31mm piece of pipe and the other skate bearing test your asembled Y slides on an 8mm running bar.

Around 20 minuets or less.

Very inspirational, thank you!

Ive bought a couple of sets of 608 skate bearings and will have a play.

Hate to mention in, youve quite a few typos in your post, Im the worlds worst typer but my school teacher eye tends to red pen every error!

Im Dyslexic usualy Midge proof reads my posts She was busy so I posted without the proof read. Hold off on copying this method I have a much better one for X and Y I am making drawings for it you will need.

32 skate bearings some plain ASDA chopping boards they are £1 for a large and a small one in one pack or just a sheet of 6mm mdf, chopping boards look better thou.
A pack of 100 Nylon blocks £6 at B&Q £5 at Wicks. I have 3 of my daughtesrs visiting so I have not had much time this week.

Once I finalize the full set of instructions with those 100 Nylon block you can make the whole Darwin cartesean bot. With the minimal effort / mechanical enginering and a few nuts and bolts.
I had these ideas several months ago but no time to do it letalone make drawings.
