  • Just a thought of advise, Thats a very high speed for drilling A little too high. a ll lube and atleast half the speed will save the bits but the hole aswell. The cutting edge needs time to ramp into the metal.

  • @M1ST3RHYDE Thanks. That was about 4 years ago, but great information.

  • @M1ST3RHYDE Thanks.  You are correct. All users should be advised.

  • oh man, i used to use a saw like that for everything!

    only recently over the last 2 years or so did i exclusively use dremel.

    and now that i just started college, i'm playing with the mills and saws. gotta try the lathe sometime =P

    props to you for working when family is around :)

  • @nitronovice Thanks for those words. Yes, the saw was tedious, but I got some much needed exercise.  We here use a horizontal band saw now.

  • I've watched this video a couple time and was wondering if there was any specific reason to tap the aluminum angle instead of just drilling and fastening the bolt with a nut. Is there a specific reason other than the additional hardware needed to double nut it?

  • @burnettprovideo You can use two nuts, but you will need to offset them enough so the ends of the screws do not conflict. Tapping will allow a more efficient length of aluminum angle and provide a more even distribution. However, a staggering patter would work fine. If you do this, make sure that the bearings are as close to middle as possible so the two aluminum angles do not touch.

  • @cptfunkstar Thanks. I am hopeful that my kids have the interest, but I will always be reasonable. :)) My wife took a lot over the years.

  • @cptfunkstar Thanks.  It's definitely fun with the family involved.
