Default I tested the spoilboard

Gary, I read your post with the attachment on it on how to test the spoilboard. If I did everything correctly the factory setting on the hurricanes is around 10 with all the valves closed and thatís what mine read, then with all the valves open Sucking through the spoil board I only got a reading around 7.5, which I know isnít good. From everything Iíve read that you posted you want a lower number. Iím looking hard for a LDF or ULDF supplier in my area, just havenít found one. I think when I do (even if I have to travel to get it) and I get my numbers lower I wonít have a problem holding most of the stuff Iíll be cutting down.

And I was thinking about doing some tracks in an MDO sheet so if I was doing smaller jobs I could vacuum the mdo down and use the tracks to hold the smaller stuff.

Default Not sure if MDF would work Carasel

This is the kind of stuff I make, horse jumps that get moved around by a lot at each horse show, loaded on trailers, strapped down and shipped cross country. Iíve used mdf before but I would rather not, if the guys moving it take care then it holds up fine but if not it can get a little flakey.

Mo..
You are correct. The numbers are too high, which means that your bleeder board is not flowing air. Did you skim both sides?

Default Yes sir

I did. I skimmed both sides, then glued the bleeder to my Plenum (I also skimmed my plenum like you told us to at the class). I used a small dollop on each of the grid squares and a single bead around each of the grids, and I left the vacuums on for about an hour afterwards. I then used the glue around the edge of the board painting it on with a small foam brush. I was worried about the small amount of glue I got on the top of my spoilboard so I skimmed it one more time.

I wonder if the glue I put around the edge is letting air through, but I can't imagine it being that drastic. I also need to get some Melamine to put around the edge of my Ply as I've only been cutting 4x8 so far on my 5x10 table. I've just today found a place here in STL that sells LDF but of course they are closed on Saturdays, but I'm going to see if they will sell single sheets and replace the spoil board asap.

Most everything has held in place so far, if not the whole sheet, then enough for me to do the cuts I've needed. I'm going to upgrade the board and hopefully that will solve my problems.

MoDuhon, seriously consider using MDO for your beautiful jump standards. MDF...even when exterior rated...is still easily damaged. MDO is essentially high-quality exterior plywood with a smooth facing that is a very popular material for signs, such as highway type signs. It's pretty durable and given how standards get thrown around, moved a lot, sometimes get trampled in the "heat of the moment" and get knocked around with "somewhat" nested storing, you'll probably get longer life out of them. Yea...less replacements...but a better quality and more durable product.

MDO is available in a variety of thicknesses...from 3/8" through 3/4"...so you can use what's best for the given profile and even use thiner material for overlay details in complex designs. My supplier (Industrial Plywood) doesn't carry 5x10, but they do have 4x10 in 3/4"

This is very likely what I'll be using for similar product offerings in my geography.

Default For sure

That's what I've done in the past Jim, I like MDO for jumps for sure. And I like to say my jumps last forever anyway. I actually made some solid plastic stick standards that actually will last forever!

Yea, I can imagine that plastic materials can last very well for this application. Of course, there are some equestrian minds that equate "plastic" with "cheap" and "undesirable"...the barn we originally had our horses with had an owner like that. I tried and tried to get her to accept that lighter weight was a nice thing and could be just as strong, but...no success. :) And she had a bad back, too. Go figure.
