There are a lot of different kinds of materials you can use for you shop jigs. I like MDF, it’s flat and is really cheap, but I’ve heard it doesn’t hold fasteners well such as screws, or nails. Birch plywood seems to be the most popular, but it’s hard to find a piece that not warp, or has cracks in it. I have never used it but heard that Finland plywood works well, but where do you get it?

Thanks for reading, I would love to hear you choices.

I usually make do with scraps of whatever I have laying around the shop. Usually it’s run-of-the-mill birch ply from HD or Lowes. I use 3/4” whenever feasible, because I find it tends to be flatter.

I use 1/2” Baltic Birch for cut off sleds and MDF for most other jigs.

I use baltic birch plywood and sometimes MDF.
3/4” does tend to be flatter.
MDF holds coarse thread screws just fine. Just make sure to pre-drill and countersink. I really think the “MDF doesn’t hold screws well” is another woodworking tall tale. The only trouble I ever had with mdf and screws was splitting, and that was before I started pre-drilling. Not a single issue since. In fact, I have a small cart I made out of MDF held together with nothing but drywall screws. 7 years old and still going strong. It has my 10” bandsaw on it now.

Whatever I have on hand…mdf, 3/4 birch.

+1 Nitewalker...predrilling and countersinking is a must…, I have experienced the mdf splitting, but also “mushrooming” if I don’t countersink the predrilled holed

I use 1/2, 5/8 or 3/4 maple plywood that is guaranteed flat over a 5’x5’ piece. Some of it is 13 ply. I get scraps from a guy that make steel rule dies. That is what I turned the mallets out of and it has no voids in it…...........Jim

Oh, add plexi to the list. It makes for great routing templates.

I have no mdf or plywood in the shop. So whatever scraps are available.

It depends how much I plan to use the jig. For jigs that will get regular use I typically use baltic birch. For project-specific jigs I will use whatever scrap I have on hand.

Whatever scraps are on hand…..MDF, MDO, ply, plexi, dimensional PVC, aluminum. I’m not fussy about it, and I can’t recall ever purchasing materials for jigs.

I think that it is best to use a systematic approach to jig making so that one jig can be easily convertible to different tasks so that the number of jigs needed is less. That way less material is required in the first place.

Whatever I have on hand, mdf, plywood, particle board, solid wood. I do like 1/4” mdf for templates and patterns.

I will sometimes use what ever is available, but I prefer MDF. I think its more stable and I have less trouble with
warping etc.
