Default A Tall Lock Miter Joint Fence for Ken & Sid

Hi Ken and Sid,

Here is the tall sliding fence I promised to show you. I got it from a tip on another web site. The first pic is the fence. 7" high mdf, jointed top and bottom and parallel. This can be clamped to your regular fence. Click to enlarge



Next pic with the sliding fence attached and a workpiece clamped in place.



Sliding fence details. The 2nd one is the back.





Here is the cut. You should do the cut in one go unless you are using plywood. Keep in mind that this is just construction quality Fir. Notice the blowout on the trails end. This is normal, but might be avoidable with a thin ply backer. I haven't tried it yet. When you run a piece through you have to apply medium hand pressure to the lower part of the workpiece, but not near the bit!





You can also do tenons with this fence. The workpiece is clamped for the face cuts. For the edge cuts I just left one of the workpieces in the clamp to act as a backer and I hand held the workpiece with the edge against the fence and the face held against the clamped piece. It worked just fine. The 2nd pic shows the tenon rounded for the poorly routed mortise in the 3rd pic.







What do you know, a perfect fit!



I hope this will help you guys out. let me know if you need any help with it.

Don't suppose you would have a plan or drawings for the parts of your plywood hold down clamp, would you ?
I can't find a source for those clamps here in Croatia.
Cheers

Hi Gav,

I couldn't get them here either, so i designed and made my own. I have posted the clamps and a picture of templates for each part on another website. I will try to round it up and post it on a thread so a lot of people can benefit. I will reference it with your name so you can easily locate it.

Hi Mike

You don't need the super tall fence and the hold down if you do it the MLCS way,it's very quick and easy..and it comes out right on the button every time.

see video, same web page

Here is another shop-made hold down clamp to get ideas from until Stefang posts his plans. This is larger, but it could be scaled down dimensionally I suppose.

Hi BJ & Paulo,

Thanks for the advice. I did try the MCLS way and it worked, but I got tired real fast of taping and tape removal. Way too slow and messy! This fence whips them out in 1,2,3 and they are more stabile during the cut. And of course I get the added benefit of being able to cut tenons quick and easy too. I just hang the fence on the wall when it's not in use. I screw it onto my fence positioner when I want to use it and I can make precise fence adjustments with a turn of the knob, which is a big advantage when getting a lock miter bit adjusted just right. In fact I like it so well that I'm making another little clamp jig for the horizontal cuts.

Those shop made clamps look great Paulo and I'm sure they work real good too and are just as good as my clamps, but mine are a lot easier (read quicker to make) and cheaper. The only hardware required for mine is a nail and two wood screws to fasten it to a jig.

Now Bj, will you believe me when I tell you that there are distinct advantages in using a tall fence. I've done perfect lock mitres in 3' tall 3/4" MDF without any form of added stabilisation, why don't you give a try sometime?
The first shot which I just pulled off the internet shows a 3' bathroom cabinet that I made about ten years ago with three mirror doors, no backing, I made MDF templates and got a glass specialist to make them complete with holes for the continental cabinet hinges.
The reason for it being on the web is that the house, which we sold a little over seven years ago for $160,000 is back on the market with an asking price "offers over $400.000" and I know they will get it. Whilst we only paid $12,700 brand new in Dec. 1967, we did an enormous amount to it.
Looking through the nine photos. indicates that internally, the only change other that the furniture, is a different dishwasher, light fittings, window treatments, floor coverings and décor, are all the same. Externally, gone are the manicured lawns, replaced with what looks like wild bush shrubs.
Anyone interested in taking a look, here is the link.

Thanks so much for the pics and instructions, can appreciate the time you invested in putting it all together. Will be heading out to the shop to begin construction of the fence. Nice looking shop Mike, must admit to being a bit of a Peeping Tom and scrolled through some of your pics on PB.

Thanks Stefan,
I found your clamps on the lumberjocks forum, so i'll give them a shot one day soon.

Hi Mike

I will agree that the tape is a PITA that's why I use a pin nailer just need to drive in a very small pin nail and it locked in place unlike the tape way.
You may say what about the holes from the nails they are so small on the stock and with a drop of water on the hole they are gone,as you know the pin nailes just push the stock to one side unlike a drill bit that removes the stock.
