Re: Sliding Table ¡°90 Degree Jig¡± #sawsetup

Hi David:

?

Thanks! I think it will work. And for sure, I am saving up for Mac¡¯s horizontal clamp in future. Have you used the horizontal component on your Kappa 400 before? I know I would use it all the time on the shaper, but I only have one set of Mac¡¯s clamps and swap them back and forth between the saw and the shaper. Or is this an excuse to buy a whole other set? ?

?

Regarding the Leitz blade, I have not used it yet so I cannot report on how it performs, but I listened to your advice (sometimes I listen!) when purchasing the slider and did not buy a 400mm blade ¡°just in case¡± but actually waited until I needed the extra depth of cut. Well, 9 years of ownership and I only now need that bigger blade.

?

The Leitz sawblade item number is 133130, 400mm diameter, 3.5mm kerf, 2.5mm body, 30mm bore, 96Z, 10 degree irregular pitch, ATB. My rep says I will absolutely love it. I hope so because it cost $320AUD. Ouch.

?

I was completely joking about the Aigner, sorry. I know some people find Aigner overly expensive so I was just having a bit of fun. The most expensive parts of my jig are the Wurth screws and the 3M blue tape.

?

Warm regards,

Lucky

Lucky,

I like your jig and it¡¯s exactly how I would go at this workflow. ?I did something similar with my K975 by adding a plywood vertical support that attached to the crosscut fence extrusion with screws into T-nuts along the face of the extrusion. ?But since the digital fence extrusion does not have T-slots along its face, what you¡¯ve come up with is the only practical way of creating a tall crosscut fence face. ?I love it. ?Mac¡¯s horizontal clamp would certainly lower the setup time for each cut. ?I¡¯d be interested in knowing the specs on your Leitz 400mm blade - tooth count and grind in particular.

?

Are you referring to the MortiseBoy jig from Aigner, or something else? ?If so, I don¡¯t see the MortiseBoy being suitable for your application. ?

I should have asked with my previous posts: Does anyone have the Aigner version of this jig? Retail price, only $1,299USD.

I love this jig, excellent idea and also looks very safe! Im waiting for my dado stack exactly for this purpose however I don't think there would be any other options other then your approach with this jig.?

I¡¯m about to embark on large ¡°half lap joints¡± style of joinery for a series of bookcases in Zebrano and Walnut (and Copper), and am using a Leitz 400mm blade. I think the best way to do this is to make 125mm deep cuts while the material is on edge. I am open to making the cuts with the material flat on the slider, stopping the cut, backing out, and then cleaning up the joints by hand. However, I have something like 280 trenches to do, so that¡¯s a minimum of 560 cuts (one per shoulder) and more hand work to square the bottom of the trenches. I¡¯ve made these kinds of joints before with a router and jig and I can tell you that programming the Kappa 400 rip fence with presets is wickedly faster and far more accurate.

Of course I¡¯d love feedback for those who can see a better way. Appreciated in advance ?

The other reason for my post is to share my little ¡°90 degree support jig¡± which is held in place using one of Mac¡¯s clamps. This setup provides excellent registration for the material which is 2200mm x 250mm x 30mm in size.


Note the high-tech blue tape to dial in the jig for square. Woo hoo.?
