Build Log
February 19, 2019
- Got parts in from 3Dhubs and Sculpteo. Everything looks good.
- Should get bearings and bolts later this week.
- Discovered an obvious bug with the current design.
- Needle unable to slide easily into slots
- Thankfully can twist into position on this print. Will use. But also tweak design for future prints.
- Need to raise/trim the top of groove on p3, or cut into base a little bit
February 15, 2019
- I mistakenly assumed 5x10x4 metric bearings (MR105) would be easy to find
- I already ordered 3D prints so im married to this size for now
- McMaster only carries expensive stainless version of this size
- Some available on amazon but they all seem dodgy, will save for last resort
- Will contact local bearing shop to see if they can order in
- Went ahead and ordered from MiSUMi
February 10, 2019
- Ordred 3D printed parts from 3Dhubs.com
- very little control over print settings
- Possible that parts will have sizing issues without being able to measure between prints
Febraury 9, 2019
- ordered laser cut parts from Sculpteo.com
- Their maximum thickness available is 1/8" or ~3.175mm.
- This is thinner than the original machine's 5mm and 6mm parts
- Taking a chance and hoping this wont be a problem structurally
January 2019
- tweaked variables so that laser cut parts will fit within 380mm width.
- This seems to be an industry standard for smaller plastic stock sheets?
December 2018
- Got design in working order, begin cleaning up issues/bugs
November 2018
- Contacted Mar from CirularKnitic
- Retstarted design work
May 27, 2018
- going to make the outside diameter for p3 about 1,000mm so that it will fit within 4 feet.
- The "Mountain" part didnt like being generated for a largr diameter machine. going to have to go back a tweak a couple things.
- looking at polycarbonate prices, seems steel is almost the same price per volume.
- will probably be easier to find a steel plate laser cutter machine shop
- thinking im going to use steel where they used polycarbonate sheets.
May 22, 2018
- getting close to finishing up variable formulas that need to be calculated based on needle dimensions
- part3 "p3" rendering incorrectly.
- diameter not expanding to accomidate more needles
May 1, 2018
- Recieved needles in the mail
- used digital calipers to take measurements
- Documented here OSE_CircularKnitic_v18.03#CKneedleVars-KH260.scad
April 2018
ordered some needles from this hong kong website http://shop.sckmcl.com.hk/product_info.php?products_id=136
- KH260 for Brother Knitting Machine Main Bed Needles 413426001
- might try using 360 needles. sounds like a nice number to shoot for.
