I have made a timber fence for my table saw sliding attachment ( approx 1500 x 40x 60), and would like to seal it against moisture to prevent any bending or distortion, while at the same time letting it slide smoothly on the table saw.

Would Carnauba wax do this, and how would it go on the ends of the fence for sealing, or should I resort to painting the fence with undercoat and enamel

If you have used a KD timber for the jig and it is indoors my advice would me nothing, keep it out of sunlight and it should be fine. Paint on machined surffaces is never a good idea. BTW, what timber did you use?

Thanks for this advice, Dills. The timber is karpur and you can see a photo of it here (http://www.woodworkforums.com/f44/triton-extension-table-added-10hb-111217/#post1092224)

A couple of coats of shellac is all use on my jigs and timber sub fences. Just make sure that you fill the end grain and an even amount of coats all over the long grain. Works for me.

Hi JillB, "pictures are worth a thousand words" you know what they say. Seeing the fence as it is I aggree with Enfield Guy, a couple of coats of shellac will do the trick. This will bring out the look if nothing else. Nice looking timber "Kapur is a large hardwood which is yellowish, pinkish or deep reddish brown" you got a good bit.

Thanks Dills and Enfield Guy for thius information. Looks like I will have to learn about shellac.
How do you make shellac, and how do you apply it? I have seen the flakes in tubs at Bunnings, but never had any interest before now.

Seeing you are un familiar with shellac a good timber oil would also do the trick. You are getting messed about here a bit aren't you. LOL.

The benevolent dictators products are the go. He has a premixed shellac that only needs to be thinned and applied. No mucking around with flakes and waiting. Highly recommended.

Just to confuse you a little more Jill.

I spray all my fences and jigs with lacquer and give them a wipe with Superglide so that things slide easily over them.

Any of the above really. I tend to brush it on jigs and the like. Saves me getting the gloves out or getting sticky stuff all over my fingies!! After all it is protection you are looking for not shine. I have a couple of fences I made from qtr sawn stock about 7 or more years ago for the old triton. Recently had a look at them and they are still as flat as the day they were made.

Thanks for the advice, everyone. Shellac it is! Plus some wax or SilverGlide

You'll need multiple coats Jill, esp on end grain.

Ubeaut Hard Shellac is great stuff - but give it several weeks to harden.

No one has suggested using danish oil. In this situation I would have thought it a little easier to use and a better finish than shellac. Or am I missing something?

Cheers

The purpose is to seal the grain to stop expansion & contraction with humidity changes. So any sealer would do, inc DO with a high prop'n of resins.

Wear resistance would be a useful by-product and some brands of DO don't perform well here. Organoil has tested among the best.
