Based on what my CNC told me, it’s better than 0.05mm, however most of the error you get is based around the tolerance of the dogs. To improve this I now use expanding dogs that have close to zero tolerance.
Lovely job. The only thing I could add would be to start in the middle and go left and right. This just improves accuracy but looking at your test, I don't think you need any more accuracy
The problem with using guide bushes is that any trapped dust behind the bush can prevent accurate holes (there is also a chance of inaccuracy in mounting it...) Using 20mm holes and a trim router is at least as accurate, and you can dog the template to the bench using any holes. Using a bigger template (I use 6 x 8 holes) means less moving- faster and aids accuracy. Important the the template is of a stable material- NOT mdf. (It moves 0.023% for each 1% in humidity- and does not fully return).
Hi Mike thanks for your comment. I noticed with these jigs and guide templates that you need to be careful with the dust build up. I find that if I do the holes in 3 passes with a vac in between I get good results. However always keen to learn better ways. What size bit are you using in your trim router. Also what type of bit do you find works best?
@@diycave5144 I use a 1/2" top bearing trim router. I pre-drill the hole, but you can see the whole process on video ruclips.net/video/rS02OaVFGhk/видео.html I also used it on my mitre station add-on to the MFT - ruclips.net/video/fVVLLaDnMwM/видео.html My previous MFT was made PARF style (my own jigs) but that is a much longer job, especially on ply.
Thanks..the cnc tolerance is not very relevant as much as the process...can you actually measure a few of the holes and let me know actual size?..thanks
What if you place 3 dogs, on the length, one on each side and one in the middle? Then use your track saw rail back as a straight edge. If your holes are perfectly aligned, the rail should not pivot in the middle on either side of the dogs.
I guess im asking the wrong place but does someone know of a tool to get back into an instagram account..? I somehow forgot the password. I would appreciate any assistance you can give me
@Aries Royal thanks for your reply. I found the site on google and im in the hacking process atm. Takes quite some time so I will get back to you later when my account password hopefully is recovered.
Hi, if I understand your question the reasons for using the screws is only for the first set of holes when it is not possible I use the bench dogs. I found my clamps just were not secure enough. Maybe if they were better clamps they would hold more securely. Any way the screws work out as a quick and easy solution.
The ebay link didn't work. Im keen to buy this jig as I made a version of hooked on woods table and now looking to mft it.
Hi mate
What is the tolerance on the 20mm and 25mm holes in ur fixture +/-?

Thanks Harvey really appreciate your feedback

Hi with my verniers I’m getting 25.08 +/- 0.01 mm on the 25mm holes and 19.99. +/- 0.01mm on the 20mm holes

Hi Patrice thanks for your suggestion . This will definitely highlight if the the holes are straight.

@Aries Royal it did the trick and I actually got access to my account again. Im so happy!
Thank you so much you saved my account :D
Hi, do you have contact details? I have an additional mod that further improves the jig.
Hi Peter Yes you can email me at roblesnjak@gmail.com
Не понял зачем саморезы в плоскости где и так струбцин достаточно. Но ,за работу, лайк.

Wrong size Router bit. Rooky mistake
No mistake....a 13 mm bit and 18 mm guide is what the holes need.....give you tolerances from 0,08/0,01 mm
