G'day Darren, thanks for your vid, well done! I have the original Incra jig with the imperial scales so work in that system, which is fine. My question is how do you adjust the fit with the box joints as that's a little tight I reckon for glue, especially for the crappy ply I want to make some boxes from. Great work on the centring jig too! Cheers mate, Sean 🙂
Hi Sean, I have good news and bad news. First the bad news. Your router bit is probably a little undersized. Perhaps from being sharpened a few times, or due to a fault in the manufacturing process. The best way to fix this is to replace the bit with a new one of good quality. I like CMT bits, but there are many other good brands available. Now the good news is that you can use the fine adjustment knob (on the carriage arm) to make the gaps on one half of the joint a little wider. You will need to experiment a little to figure out how much you need to widen the joint by, but the width of a piece of paper is probably going to be plenty. I hope this makes sense. Cheers Darren
@@DarrensWorkshop thanks Darren. 🙂 mine is the original Incra jig (bought at a market 20 ys ago, but still sold by Timbecon I see) so no fine adjustment knob for me, although there are workarounds. I think you mean use the template to make the cuts once, then adjust the carriage a given amount (say, paper thickness as you say) then do the same set of cuts again - is that right?
@@3888Orbost Hi Sean. The is it. For example if you are making a box, you would want to make the pins on the side pieces slightly narrower than those on the front pieces. Try and keep then symmetrical though, which will mean turning the timber so both sides of the pins are shaved. Perhaps you could use shims between the jig and the fence to achieve this. Good luck, let me know how you go.
Hi Darren,Just found your site , I Have been trying to find the centre finder online, do you have the part Number? I also watch your fusion 360 video "great" what filament & printer did you use and if you were goingto replace your printer which one would you buy.
Hi Frankis. I'm sorry. There is nothing written on the centre finder, and I can't find it on the Incra website either. I used eSun PLA+ on a Prusa MK3. This actually is the one I chose when I upgraded. I had an XYZ Davinci Pro before that. I'm very happy with the Prusa and eSun, but wouldn't recommend XYZ.
Darren this jig is exactly what I am locking for, any chance of a drawing "willing to buy" . currently use sketchup but any drawing will do , you are right the recommended centring is a pain when you have old eyes. regards Frank. Just for your information I use Makita batteries But buy some Ryobi tools bare and fit an adaptor which works great and stops me having to have a extra battery platform
Hi Frankis, I have created a version of the Router table centre finder and tested it. The models and original drawings are available here. cults3d.com/en/3d-model/tool/router-table-centre-finder. I have done it as a 3D print. But you could follow the dimensions of the drawing and build one from aluminium if you wanted. Have a great day, Darren
You made one big mistake. You didn't clamp the Right Angle Fixture to the bench top when setting up your wood. This allowed the fixture to move or tilt a bit when setting up your wood on it and prevented the cuts from coming out perfect. Dovetails require precision and if you aren't precises when you set up your jig, you will have problems.
Hi, no I didn’t make a mistake. The way I do it is the way it is shown in the Incra manual. I’ve been doing that way for many years and it is accurate. The right angle fixture attaches to the fence with three nylon screws. These hold it in place. There is no need to clam it to the bench. That said if you like your way of doing it, keep doing it that way.
I haven't seen the Incra centering jig before. Seems like a real time saver if it works with the accuracy required.
Great no bs instructional video - the new centre finder is a great idea!
Subscribed!
Thanks Brian. Have a great day.

Hi, I'll sort something out. Just give me a couple of weeks.

Yes, Imperial racks are black.
