    Rider feet for machines

    @FredC: Cant't correct title once submitted :( @L Vanice The CV-59 is about the right height. The Clausing next to is the one I want to raise up. ~5" is the right spot. The Hardinge cabinet is curious to me- it looks like it already has 3 'hard' spots that it sits on (Its been a while since I...

    Rider feet for machines

    Hi all - I am wanting to raise my primary machines to make them more ergonomic. Has anyone raied their machines up like this? I am reorganizeng/cleaning and have the manual op lathes on skates and realized how much more natural they feel 6"-8" higher. I can't believe no one has seemed to...

    Source for MK8 M7 nozzles (for Qidi X-Plus II)?

    Good nozzles do not fix crappy filament or a shitty print. Having consistent extrusion from a nozzle removes that variable from the equation. To put it in perspective: I have been int he reprap game for 10 years now. I have seen all sorts of things come and go. Consistency and repeatability is...

    Source for MK8 M7 nozzles (for Qidi X-Plus II)?

    By performance do you mean how do the original prodcuts work compared to the Chinese knock offs? Micro-swiss developed the first Mk10 all metal nozzle and heatbreak. Runice has not been able to match it. You will want to upgrade the rest of the Mk10 extruder parts to their all metal ones...

    Their nozzles are the best. USA made and their coatings really do work.

    RPC Schematic questions

    Greetings all- Below is the schematic for a RPC that I built ~10 years ago. I think I bought the kit from Niagara off of ebay. (Is this the WNY converter guy now?). It's been running my stuff fine as is. I have a couple of 1 to 1.5hp tools that run off of this. Sometimes one runs idle while I...

    Weight capacity of I-beam with chain fall

    Walt - I know that you are trying to be helpful, but please refrain for spreading mis-information. The fact that you have done it this before does not mean that you know it, but that you have been lucky since none of them have fallen down! Your math and theory is not correct. This is why we...

    Weight capacity of I-beam with chain fall

    carla- your description of the beam makes me wonder if its even A36, could be A9 or A7 or older. 16ksi-33ksi. bottom line, consult a local engineer. its not as easy a looking it up in a table. you should read the fine print under those tables.... as soon as you put on supporting member...

    v belt size

    paula- i respectfully disagree. link belts have a place, the primary drive is not one of them. using them in place of a flat belt is not one either. using them on a v-belt spindle machine, between the intermediate shaft pulley and the spindle is the right application. you are right, those...

    v belt size

    let me repeat myself.... listen to ALL the words. don't use a link belt between the motor and the intermediate shaft.the pulley on the intermediate shaft driven by the motor is FLAT with no grooves. a linked belt won't work right on this sheave. if you have a v-belt driven spindle, the belt...
