Where to buy spindle

This hopefully gives you a better idea of what forces are needed for Ice

To be honest I would imagine the forces are a bit less than cutting soft woods so your design is well upto the job.
Personally given your relatively light needs then I would use HD Aluminium profile for the gantry beams and make life very easy for your self. The profile makes fitting rails very easy and accurate, if combined with Aluminium plate for the gantry sides that is manipulated in a certain way then it's very accurate and strong.
Steel is great when mass strength is needed but there is alot of work involved in building with it and getting accurecy. The combination of steel for the base for cost saving and strength but with the ease of building an accurate but still strong gantry with profile/plate is the route I would be taking.

Hi Vass, what servos you are looking at? You said 750w and 400w but what exactly ? The BOB then? Do you have updated drawings yet?

Hi There,

I have managed to do some work on the servo mounts yesterday and thought I ask for opinions. I have tried to make it simple and easy to build.

The orangebits are 10mm steel.

24 t pulley on the servo and 48 t pulley on the ballscrew. The bigger pulley in the picture is the 72 t pulley if I want to go with 3:1 reduction.

Opinions would be great as I am planning to send the final drowings for laser cut sunday night as the place where I do my laser cutting switches to thick metals on monday and tuesdays.

O and how much extra space is advisable for the paint layer? 1mm maybe?


Thanks,
Vass

Just a quick point how about making the slots in the motor mounts longer to enable you to be able to change the pulley size if needed later. ..Clive
