I’m sorry I’ve been asking a lot more questions and I’ve been contributing less, but hopefully that will change soon when I can at least post some pictures of a few finished projects.

In the meantime, can anyone tell me what the best material is to make a router template out of? The template I’m going to make will be about 1 square foot, with many many different sweeping curves. What I’d like is something dense enough that it doesn’t dent or flex. I’d also like it to sand quickly so I can file/sand it to shape. I do not have an oscilating spindle sander so the sanding is really important.

Do most people use MDF? MY experiece is that is doesn’t sand really smooth and ends up a bit furry. I appreciate the help.
Thanks!

Furriness probably doesn’t matter for a router template in the case of MDF. The 1/128” that it could possibly add would be negligible. I’ve had pretty good success with 1/4” hardboard. As long as your bearing will fit on it it’s easy to cut with a scroll/band saw and stiff enough.

I like 1/8 inch tempered hardboard (Masonite.)

I’ve always used 1/2” MDF with good success so I haven’t experimented with anything else. Sands and shapes easily enough and holds a smooth edge for routing.

The material you use might depend on how durable the template has to be. If it is going to be used a lot, then I would recommend tempered hardboard as Joe did. If it’s a limited use, the 1/4” MDF is a good choice.

My 2 cents: Why not laminate 2 pieces of 1/4” tempered hardboard (Masonite) together that would give you almost 1/2” of surface for your bearing to ride on? If you left the shiny side out there would be no finishing involved and you’d have a good surface on either side for the double stick tape…..Masonite is fairly economical.

Anything flat. MDF, tempered hardboard.

Lexan if you want to use it forever.

Have you considered plastic? Clear plexi can be found at the big box stores in small (2’ x 2’ or so) pieces. You can find 1/4” thick stuff and then you can see very well where you are about to cut. I think its nice to be able to see “both sides” of the line.

sounds like I need to find some hardboard. I’d love to do the lexan thing, but my experience with it has not been good. This is mostly because I don’t have the right tools to cut it, and I’d rather not invest in that stuff. Thanks everyone. I’ll let you know how it all comes out.

I use a lot of MDF and some Plexiglas for more permanent templates. If you’re having trouble sanding MDF, there is a difference in brands and type. I only use Plum Creek 2. It sands really well. it is denser than some others. Not all MDF is created equal.

masonite… I just have too much of it.. and it has a smooth surface, thin, and easy to machine, works great!

well, i tried lowes for hardboard today, but all they had was perforated stuff. thats obviously not going to work. I guess I’ll try some of my scrap mdf after all. I really wanted to try something better, but oh well. I think the real winner would have been if I could have found that platic that everyone uses for jigs (looks like a cutting board material), but I didn’t run accross that either. Oh well, back to work with what I could find.

1/2” MDF works for me…

1/4” lexan/Plexiglas if I need to see through it.

I haven’t needed any ‘forever’ patterns, yet, but would consider Phenolic sheet like:

are you talking about HDPE High-density polyethylene? That stuff is used a lot. If you google plastic dealers you will probably find one in your area. Near St. Louis there are a few that sell this stuff like sheet goods.

I’ll agree with most. It depends. I use hardboard mostly as it is fairly durable, cheap, and easy to tool. However, if I was making a template that would be used many times over the years, I might upgrade to a plastic for where and tear reasons. Melamine is another option, harsher on the tools though.

About Lowes, I’ve had better luck with Home Depot for MDF and Hardboard. They have both in many sizes and such. My Lowe’s pretty much only has the 4’x8’ sheets.
