Knocked this up!

[mailee]

Now I have a powerful table saw I decided to knock up a tennoning jig for it over the weekend. I had seen the Dakota one at Rutlands and thought i could make something along similar lines. Here is my effort:

Seems to do the job well enough and worth a few hours building it.
I did just notice that the Dakota one has been reduced again, ah well, it has kept me amused.

How well does it work? You know you can always pretty it up as long as it does the job. Not sure about the G clamp though. I would love the Delta one that El Norm uses but I dont have a working table saw so it can probably wait for now . Making any other new toys this Xmas?

Regards Tom

 

[mailee]

Thanks Tom. I agree about the 'G' cramp but I needed something that would hold it but allow it to pivot for angled cuts. I may work on this idea and see what I can come up with. I may end up with a clamp attached to the vertical fence to allow the fence to swing. Seems pretty accurate though and that is the main thing.

 

[Woodmagnet]

Nice one Mailee. :wink:

 

[motownmartin]

Nice one Alan, I made a similar jig but its fixed at 90 degrees, might be modifying it though

I'm not a fan of tenon-cutting on the table saw but I do like your jig and how you've designed it to be adjustable like that.

Have you go anything planned in the way of adding a guard?

 

[mailee]

Yes Olly, I keep my fingers on the oppostie side to the blade. :wink:

 

[BradNaylor]

I have always shied away from cutting tenons on the table saw as until recently I employed staff and such a technique breaks H&S regulations as it invoves the removal of the guard and riving knife.

However, I am no longer an employer and am thus liberated from such constraints!

I like your jig Mailee, but would you really recommend building one or should I go for the Dakota at seventy quid?

 

[mailee]

Well Dan, it just happened I had the time on my hands to build one. I would have bought one especially at the reduced price now but thought I would have a go at my own. Besides there is some satisfaction in making one and finding it works well. :wink:

Thanks Mailee,

I guess I'll go for the Dakota then!

Time is money and all that...

Looks a useful jig.
However, I may be a bit of a wimp, but I dont like clamps around a tablesaw blade in case a clamp (for some reason) should fall off and down and land on the blade.

It will happen somewhere someday.

Ps. I myself have bookmarked your jig but I am going to think how to stop a clamp or fastening system like I have mentioned above could happen.

 

[mailee]

I have to agree with you Devonwoody. The clamp is there just to test the setup and I am working on a permanent fixture to hold the timber. Maybe something attached to the backing fence that could be adjustable for varing widths of timber. Am working on it. :wink:

 

[mailee]

Sorted it now. I had a clamp from my old SCMS and used this. I had to change the upright fence for one of Oak so it wouldn't flex and used a threaded insert for the clamp. Works well and cuts accurately too.

 

[devonwoody]

Mailee, you have made me very happy

But I suppose you have lost the swivel action?

Bookmarked again.

 

[mailee]

No not at all. This is the reason I used the oak as I could then secure the clamp into the moveable fence. It still has it's full 45 degree angle adjustment. The clamp is held into the fence with a grub screw (seen in the rear view) which screws into a nut inset into the inside of the fence. This then locates on a ridge on the end of the clamp rod. Pretty sturdy and it clamps pretty tight too.

Sounds good. Next time I'm into tenons I will make one for myself.

Mailee,

I've just started kitting out my first workshop and want to build benches with mortice and tenon joints, so the first thing I've made in the shop was a mortice jig similar to yours (got the plans off the internet)

This is going to sound stupid but I have built it but don't understand one part of it. There is a slot thats been cut to allow the jig to slide forward but if it slides to the full extent of the slot the jig would be over the blade (and would cut it in half !). I've checked all my measurements and am sure I've built it right, now looking at yours it seems to be the same sort of thing, can you explain what that slot is for ??

Hopefully I've marked the slot on the attached picture !! :

 

[mailee]

Yes Genghis. The slot is to allow the tennon to be fine tuned. The slot is a little large and yes it would cut the jig if it were fully adjusted to it's stops. To use it mark the position of the tennon on your timber and then clamp it to the fence. Adjust the fence using the slot until the blade will cut just shy of your marked line. I always make a test cut first to ensure the tennon will be a snug fit in the mortice. You will notice on my version there is a screw thread on the base plate as well as a bristol lever to clamp the base once set. This threaded rod enables tiny amounts to be dialled in and once correct then the base is clamped. Hope this helps you. :wink:

 

[LarryS.]

Mailee,

thanks for the rapid response, and confirming I hadn't gone nuts (much to the disagreement of the missus).

The screw thread looks like a great idea which I will copy / steal / plagerise.

Have you built any other jigs for the saw which you find useful (I'm just starting out so want to kit the workshop out with anything that which will counteract my lack of skill) !!

cheers

I have only had this saw set up for a couple of weeks so far so am still makiing jigs when time permits. I do have a couple of other jigs that I made for my old table saw. (Power Pro B&Q special) I made a tapering jig which I can also use on this saw as it runs against the fence. Also a straight edge jig which also uses the fence and consists of a board with two parallel edges and two clamps which hold waney edge boards to be cut parallel and true to the fence. I am afraid I don't have any pictures of them but could take some tomorrow after work for you to see. I have also made a out feed table for this saw which was a copy of one Steve Maskery made for his Excalibur, this folds down flat against the casing to alow more room when not in use. :wink:
