Urethane Cutting Edge for Blade

[drspiff]

You could try United States Plastics in Lima, OH. They have everything plastic - and the profits go to a great cause!!!

As I was looking through the US Plastics site, I think I found what you need.

This is 1/2" thick HDPE 18"x60" for 53.20.

You could get 4 blades, 4 3/8" wide, or 3 blades 5 7/8" wide, allowing for 1/8" saw kerfs. The cost per blade is going to be $13.30 for the 4 3/8" and $17.74 for the 5 7/8" blade.

Here are a couple of quick thoughts -

All plastics are not the same. There are many different combinations of strength, wear, chemical resistance etc... qualities available, and I'm pretty sure that something like Trex will leave you disappointed.

Most plastic commercial plows that I'm aware of use polyurethane, so probably the best place to start. McMaster-Carr and MSC are good sources, but not necessarily the cheapest ones. (Both great resources, and everyone should have copies of their catalogs, by the way)

We use this material all the time to fabricate race car skid pads because of it's wear resistance. It's easy to work with, but I should warn everyone that cutting it on a table saw under certain circumstances can be a a little shakey. If you cut too slowly, or have a dull blade, the plastic can melt, rather than cut cleanly, and stick to the blade - with REALLY exciting results! You may ask how I know this...

Be careful,

Ed

With the top piece of metal not on my blade, can you use black plastic culvert tubing or does metal work better to move more snow, or don't it matter?
