Y Rod mount amd Y motor mount

Y Rod mount amd Y motor mount this uses the Nylon corner fixing blocks and 6mm or 1/4 MDF the ASDA Chopping block is to flexible for these parts... ;( as I tried.



Y Slider Rod mounting blocks

Materials :-

2 Nylon corner fixing blocks with the central hole drilled out to 8.5mm. (8.5 mm bearing blocks)
1 Nylon corner fixing blocks with the central hole drilled out to 6.5mm. (6.5 mm bearing block)
4 Nylon corner fixing blocks with all the holes drilled out to 8mm.
13 Nylon corner fixing blocks as they come.
2 8mm Steel bar 500mm long
6 4mm machine screws 50mm long.
2 4mm machine screws 35mm long.
28 4mm nuts.
A small piece of 6mm MDF

Tools used:-
Pedestal drill, 8.5mm, 8mm, 6.5 mm, 4mm, 3mm drills, Wood saw and vice.
or
Hand held drill, 8.5mm, 8mm, 6.5 mm, 4mm, 3mm drills, Wood saw and vice.


Method used:-

Note:- You must use a vice or make a little jig to hold the Nylon corner fixing blocks not only for safety but to maintain accuracy.

Clamped the Nylon corner fixing blocks in the vice then re-drill the single 4mm hole two with an 8.5mm drill 4 with the 8mm drill and one with the 6.5mm drill.

Then make three MDF Rod mount plates like this.



Now assemble the two bearing assemblies using the 6 4mm machine screws 60mm long.
Three standard Nylon corner fixing blocks with one 8.5 bearing Nylon corner fixing blocks.
Each assembly is made so that the screw heads and nuts are set into the counter bores of the 4mm mounting holes. the completed assemblies are then bolted to the Y axis slider rod mounting plate on the 4mm holes nearest the edge of the plate. The slider rod end stop is also a standard Nylon corner fixing block this screwed into the pair of 4mm holes in he middle of the plate. Repeat this for the single 6.5 mm bearing block just fit the 6.5mm beaing block instead of an 8mm one. This is makes a pair with the stepper motor mounting assembly.






Then make one of MDF Rod & motor mount plates. Note if you are using Bike chain as your drive you must make a four sided housing. Else just make the first two plates



Now assemble the stepper motor mounting assemblie using the 2 4mm machine screws 35mm long. Two standard Nylon corner fixing blocks are screwd together using the 35mm screws then they are bolted to the Y axis Stepper motor slider rod mounting plate on the 4mm holes nearest the edge of the plate. The slider rod end stop is also a standard Nylon corner fixing block this screwed into the pair of 4mm holes in he middle of the plate. Repeat this for the single 6.5 mm bearing block just fit the 6.5mm beaing block instead of an 8mm one. This is makes a pair with the stepper motor mounting assembly.

Then make one of MDF motor mount plate.
(Note adjust the 16mm centers to suit your stepper motors)



Top plate for Chain drive system.



Inner End plate for four sided motor mount using bike chain.






Now assemble the stepper motor mounting assemblie using the 2 4mm machine screws 35mm long. Two standard Nylon corner fixing blocks are screwd together using the 35mm screws then they are bolted to the Y axis Stepper motor slider rod mounting plate on the 4mm holes nearest the edge of the plate. The slider rod end stop is also a standard Nylon corner fixing block this screwed into the pair of 4mm holes in he middle of the plate. Repeat this for the single 6.5 mm bearing block just fit the 6.5mm beaing block instead of an 8mm one. This is makes a pair with the stepper motor mounting assembly.


Now the Y Slider rails can be hammerd with a rubber hammer into place any extra length of the slider rails must be at the pulley end not the stepper end of the assembly .




Time taken:-
Around 30 minuets or less.

X and Y axis sliders method 3

X and Y axis sliders method I have just tyed this method wich is even simpler it avoids using skate bearings altogether and just uses the Nylon corner fixing blocks.

I am total amazed by this one I expected this to have more friction than the skate bearings and for it to have a lot of play.. neither is the case it is also very very much lighter as it has not got 32 skate bearings. I cant belive how simple the X & Y mechanisims are now and its £16 cheaper to buy..


Here are the pictures of the construction.. :-




Y slider build

Materials :-

8 Nylon corner fixing blocks with the central hole drilled out to 8mm.
4 Nylon corner fixing blocks with the central hole drilled out to 8.5mm.

or
Hand held drill, 22mm wood bit, 8.5mm, 8mm, 4mm, 3mm drills, Wood saw and vice.


Method used:-

Note:- You must use a vice or make a little jig to hold the Nylon corner fixing blocks not only for safety but to maintain accuracy.

Clamped the Nylon corner fixing block in the vice then re-drill the single 4mm hole with the 8mm drill.



Make two of these drive belt / chain clamp plates.




Make the two Y slider plates from the Chopping board cut 2 pieces 75mm x 95mm.
One piece is for the X stepper motor the other for the X pulley. So for the stepper end drill out the four 3mm motor mounting holes and the central hole is drilled out to 22mm. On the pulley end X-Y slider only the central pulley hole needs to be drilled out to 8mm. The red marked holes are drilled out to 4mm. The other 8 holes are 3mm for tie wrapping the Y axis chain or belt to the slider.



Now make the four bearing assemblies using the 8 4mm machine screws 50mm long.
Each assembly is made so that the screw heads and nuts are set into the counter bores of the 4mm mounting holes.

The asembly is so simple jst look at the pictures now.

Now the x Slider rails can be hammerd with a rubber hammer into place any extra length of the slider rails must be at the pulley end not the stepper end of the assembly .




Time taken:-
Around 30 minuets or less.

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.

Making 20 Diagonal tie brackets & 4 anti vibration feet

Materials :-
I pack of 24 Nylon corner fixing blocks.

Tools used:-
Pedestal drill, 8 mm standard drill, bolt down pedestal drill vice.
Or
Hand held drill, 8 mm standard drill and small vice.

Method used:-

Note:- You must use a vice or make a little jig to hold the nylon corner brackets. The hard nylon corner blocks really do hurt if they get to spin on the end of the drill.

Clamped the Nylon corner fixing block in the vice then re-drill the 5mm hole with the 8mm drill flip through 90 degrees and drill the other hole.

As there is already a hole in the Nylon corner fixing blocks the drill will self centre. As you are drilling plastic the drill will snatch and spin the block if you are not using a vice if you make a jig to drill several at once make sure it holds the top block down as well as preventing spinning.


Time taken:-
Around 30 minuets or less.

Drawing:-
None re-drilling holes.

Making 4 anti-vibration feet.

Materials :-
2 packs of two rubber door stops.
1 pack of four 25mm washers.

Tools used:-
Pedestal drill, 8 mm standard drill, bolt down pedestal drill vice.
Or
Hand held drill, 8 mm standard drill and small vice.

Method used:-

Note:- You must use a vice as any spinning object is dangerous

Clamped the rubber door stop then re-drill the 5mm hole with the 8mm drill.

As there is already a hole in the rubber door stop the drill will self centre. As you are drilling rubber it can snatch and spin.


Time taken:-
Around 10 minuets or less.

Drawing:-
None re-use of door stops.
