I am going to order my stainless steel tubes on Monday. 25mm OD x 2mm WT. Lowrider 2.
I’m using the JSCalc.io calculator in mm for the Lowrider2 CNC.
I am going with a X-Usable Width of 1100mm (I read a comment on the V1 site that 1200mm is really the max you would want to go). And I am planning a Y-Usable Length of 1700mm. (Please let me know if you think 1100 is going to problematic)
I have some questions that I really need your help with before I go to order on Monday morning….
When you guys buy your tubes, do you round up the number a bit or do you cut to the exact dimension the JSCalc Output value gives you?
How do you decide on the correct Z-Usable Height value? When you first visit the JSCalc page, it already has an input value of 89mm. I really have no clue what height value to choose.
Again, do you round up on the Z Height tubes length when ordering?
At the moment, the supplier has told me that the welded tubes have the seam on the inside - which is great so as not to interfere with the bearings going back and forth. But I asked him about the finish, and he said they had ‘scale’ to them - not satin and not polished. I am not familiar with this term. Is it a standard term that shouldn’t be a worry for my project, or do I need to have them polished??
Problem is I am ordering from abroad and cant see first hand. I am hoping the vendor will be able to send me a quick picture - just hope the tubes are suitable because I have been finding it very difficult to find reasonably valued 25mm OD x 2mm WT tubing in Europe.
Your help is very much appreciated!!! Thank you!!
