Hi Chris I just used standard 1m steel rulers. I had the holes drilled by a machine shop. I tried doing it on my drill press but couldn’t get better than about +/- 0.3 mm per hole. The machine shop was at least 20 times better . It did cost $80 to do the two rulers at the machine shop.
For an MFT table, the holes not only need to be spaced accurately, but they need to be perfectly in line and perpendicular to each other. If you’re using the holes for clamping and don’t want it for accurate cutting I would think the divider method would be fine.
@@diycave5144I would think dividers would be just as accurate if not more if you use the dividers to construct a right angle and then work all ways using the dividers. It would at least save having rulers cnc’d for setting out holes. I certainly think your jigs for drilling vertical holes makes for accurate perpendicular drilling.
Hi, I like your work. Well done. Please allow me a few questions. I also try to build a jig like this. Why exactly failed the to diy rulers? What was your method? Did you use spacers or the scale on the rulers to drill the 3mm holes? Did you pre-drill with a 1mm drill? Or directly with 3mm? Best regards Robert
Hi Thanks for you feedback. The DIY rulers essentially failed as I couldnt get enough accuracy with using the drill press I have. Although I tried several bits to pre-drill, such as a spot drill and centre drill bit and whilst this was an improvement, my accuracy was between 0.1-0.3mm per hole. So over the length of a 1m rule that error was compounded. I also tried just punching the mark on the rulers but this didnt work that well for me. In the end I went to a machine shop who used a CNC drilling machine that could do better than 0.01mm between holes. Now you may be able to get better results perhaps if you have more experience and maybe better equipment. The spacers were definitely a guide but I also used a jig with a predrilled hole that I could move the ruler and pin it in position with more accuracy. But the issue was simply with the movement in the drill bit. Also I used 2 guides as opposed to one, because I found I could get more accuracy if I made two guides. I experimented originally with one guide but found that I got better accuracy from 2. Good Luck
Much better than your first video. Good effort.
Hi. Great work. How did you make the drill bit aligner (shown at 2.05 minute of the video)? Thanks
Where did you get the ruler with 96mm spacing holes?

Hi, great job! I have a question, how many mm from the end of the rulers did you leave to start marking the 96mm spaced holes? Thank you so much!
Hi the first hole on the ruler is at 20mm in.
Using a pair of dividers would allow you to set out the holes accurately and you could set the holes at any set distance.
For an MFT table, the holes not only need to be spaced accurately, but they need to be perfectly in line and perpendicular to each other. If you’re using the holes for clamping and don’t want it for accurate cutting I would think the divider method would be fine.

@@riptizsure go ahead and try and do it with a divider. Then tell us what your results were.
