Thanks that is what I was looking for.Seems like you should have included setting the teeth in your video. As it is the saw blade illustrated is useless.
- Ralphxyz commented on Mikhandmaker.'s instructable Filer Guide for Hand-SawsView Instructable »
At the begging of the great video you hammer the teeth removing the set.Then you flatten the teeth and proceed to sharpening the teeth using your great device.How do you re-set the teeth? As it looks you have nicely sharpened angles all in a straight line I do not see how that would cut very well without set to the teeth.Ralph

- Ralphxyz commented on Mikhandmaker.'s instructable Homemade Lathe for Drill PressView Instructable »
FLQPKNL9MB, having a little trouble understanding exactly what you are saying.To begin what do you mean "the chuck fits as a cone"? Then I know you cannot (well should not) use a drill press as a mill where one applies lateral stress (pushing) against the spindle (chuck) but would turning wood produce that much lateral stress? It would be working in a shearing motion not a milling motion. Thanks for the reply.

Well it is working!!Turns out the center pin was ground!!Wooowee, thank you Sinom!!
Thank you Simon for the reply.Yes, if I reverse the wires it is just the opposite, no increment.It only works on every detent in one direction.I tried with a different encoder, one that has no detents and everyfull turn increments and decrements correctly.Ralph

- Ralphxyz commented on SimonM83's instructable Improved Arduino Rotary Encoder ReadingView Instructable »
Hi Simon, thank you for able, My encoder is a no name ebay encoder.It works great for increment but does not decrement.On increment every detent is counted on decrement sometimes one sometimes 2 sometimes 13 sometimes 23 detents are passed before a decrement shows up.Depending on which wires to pin 2 and 3 I can get increment or decrement but not both.Without decrement it is not really usable!Ralph

Soft, easy to work with metal.Actually you are case hardening the wire when you dunk it. Just let it air cool to be truly tempered. Case hardening just hardens the outside layer of the wire the inside stays soft, possible you are using the hardening effect.Anyway I love it, thanks again.

Thanks AeroSpaceWatercraft, that's what I am considering.This would be just an one time use so I do not think I care that the cornstarch and the detergent burned away as long as the sand held it's shape while the metal filled the mould. Of course I do not even know what green sand might cost.

- Ralphxyz commented on Mr innovative's instructable How to Make Arduino Based Digital Tachometer Simple DIY TutorialView Instructable »
the thing is that all that should be done within the interrupt is the counter is increased period. Nothing else. If you need a delay do it outside of the interrupt.
- Ralphxyz commented on Mr innovative's instructable How to Make Arduino Based Digital Tachometer Simple DIY TutorialView Instructable »
Your interrupt does not look very efficient, I thought one wants to be in and out of an interrupt as fast as possible, you even have a delay in it. Of course as you are only doing one thing it probable does not matter. I would be doing more things.
