Default Advice? - Holding small pieces for Chamfering

I'm planning on putting a 1/4" chamfer on a number of pieces of 1/2" MDF that are 1-1/4" square and others 2-1/2" square, and looking for the safest approach.

For 2 of the sides, it's straightforward as I can chamfer them in long strips (i.e. 48" x 1-1/4" or 2-1/2" x 48") before cutting them to length. For the other cut, I was contemplating holding them in a Jorgenson wooden hand screw clamp, with the piece extending slightly from between the wooden jaws.

Is this the safest way, or should I use my 23ga pin nailer to attach them to a piece of 1/2" MDF and use my Colt on them or ?????

Jim,
The clamps would work, If you have the little 6" ones, I think the large ones would be a pain. But if it was me, I would line them up on a strip of plywood, using the fiber Duck two-sided tape. That stuff holds really good. Wouldn't hurt to tack the first and last one, if you wanted to be extra safe.

Cut it twice, and it's still too short!

Jim browsing through a Woodcraft catalog I saw a jig to hold small pieces listed, can't find it just now and also went to their web page and couldn't find it. Perhaps someone else will have a jig for this purpose and can post it. If I find it later I will PM where it is. I know when I saw it I wanted to get one for myself.

I think this is what Jerry was thinking of:

Price seems pretty reasonable but I don't see why your idea of using the clamps or Harry's idea about attaching them to a piece of plywood wouldn't work also.

The problem with experience is I usually get it immediately after I need it.

Ya like the man said MLCS has the thing. I knew that, just checking to see if anyone was aleart!! Thank you John for finding that thing---was sure it was that other place though!! At 65 it is called a senior moment.

I think I would like to get one from them unless I can come up with a good jig, easy to use and quick to set up. Again thanks John for bailing me out there, now I can quit looking!!

Hi Jim
It sounds like you got the way but you may want to try the ski jig way,,you just need to put them on the cam board use 4 cams lock them in place do all 4 edges at one time then flip it over and do it one more time and you have them done, you don't need to use the ski jig just lock them it in place and run your Colt all the way around them ...

The tape works well but not as fast as the cam board plus you don't need to remove the tape when you need to flip them over plus the tape likes to move just a little bit unlike the cam way

If you don't have a cam board on hand and the cams you can use some scrap stock for one and cut off some 1" dowel rod and drill some holes off center,screw them down to the board and then put your part in place and turn the cams to lock the project in place, but I'm sure once you get the project done you make a cam board...

Hi John,

I had one up until about a month ago and ended up giving it away. Too flimsy to feel safe for my taste. Better off with the wood screw clamp and save your money.

Default Small Peices

Hi BigJim,

Just sandwich them between two boards - say 1x3's a foot or two long - allowing them to overhang one edge enough for the sled to clear the bit without being cut into.

Line the pieces up against each other in a row to a "fence" of the same thickness and equal to the length of the 1x3's, then screw the top 1x3 over them through the fence "sandwiching" them in place, and you're good to go. Using two-way tape would also be a way to go, but I'm unsure that tape alone would be sufficient for peices of this (small) size. With pieces this small, it would be a good idea to use the tape in the sandwich, otherwise, they might have a tendency to want to "rotate" slightly as they pass through the bit.

This securing method is quite simple, it's fast, nothing fancy needed and works for many different applications.


good luck with your project,
Bob Carreiro

If you only have a few, I would use a hand screw. My next choice would be to build a sled to hold the workpiece while I cut the chamfer on my router table.

Thamks guys, you've validated my idea. I've also thought that if it's iffy on holding tight enough, I can take a scrap of sandpaper, fold it in half and add a little glue on the paper side. Sandwich a piece between each jaw and the MDF and it'll be locked in solid, once clamped.

Bob... A cam board is smack dab on my to-do list. Now just to figure how large to make it. I'm kinda thinking about 24"x36". I suppose I should check to see what sized threaded rod is available locally first! <g>
