Building a box and using Trupan Ultralite for the first time. OMFG this **** is sweet. Cuts like butter and minimal sawdust. I made around 20 cuts and literally had the same amount of dust on the floor as 2 MDF cuts. It just glides through the saw and being lighter is another bonus.

I had to track down the US rep and he got me in contact with a lumber yard 8 minutes from home. Ordered Thursday afternoon and they had it Friday morning. They ordered 3 extra sheets, so they'd have some in stock. Paid around $48 a sheet and WELL worth it to me.

Next few builds I do for anyone, I'll be pushing this stuff for sure.

Props to BJfish for making me aware of it. :thumbsup:

Is it 3/4" or 5/8"? I have only used 3/4" trupan light and 5/8" ultra light...

3/4" ultra light.

Cuts, drills, sands SOOOOOO much nicer than MDF!!!!

for a fiberglass box, you can spend all the money on that or buy some birch plywood for about half the cost. both will weigh alot less than regular MDF

The Trupan is $8 more a sheet compared to the HD BB which is NOT marine grade 13ply. The REAL stuff is MORE than Trupan :eek:

I think that the point was in a fiberglass enclosure it doesn't matter that much and both are lighter than MDF.

I was just saying for $8 more it's MUCHO nicer to work with and void free for sure. BB at HD has been hit or miss for me lately...

I've used the birch ply from HD and Lowe's and sometimes they have the good stuff and sometimes they don't. For a fiberglass box, where the bulk of the box is fiberglass, just about anything will work. Once it's well covered in resin, the type of wood is pretty much moot and there isn't enough wood there to make much of a weight difference either.

does trupan have the same durability as normal MDF or will it flex? Deff. using this on my next box if i can find a lumber yard to get it form.

BJfish can probably answer that better as this is my first box and won't be done until later in the week.

Seems VERY solid though and I always brace my boxes, so no worries...

Rob Mortonsen (?) is the US rep. I've got his number at work and can post it if you want. He'll be able to point you to a lumber yard close to you that can get it.

Cut my 45's for the corners today and my table saw really struggles with MDF, but this stuff cut smooth as silk.

Never seen a tablesaw struggle with MDF... what blade do you have on it? I use a cheap carbide blade from HD ($20) and I've been using it for close to 2 yrs now. Still like a hot knife through butter on MDF. Slightly less efficient on plywood.

Normal cuts are fine, but the 45's are a ***** with MDF. It's a pretty decent $40 Craftsman carbide blade.

When doing the 45's you're cutting around 1 1/2" of material and it's probably the motor more than the blade as it's a pretty small table saw.

I noticed a big diff when doing the 45's using the Trupan as it just cut much easier.

Anyone looking to buy Trupan, US Rep is Rob Mortonsen 425-258-2217. He'll be able to locate a local lumber yard that will order it for you, or that might have it in stock.

Pretty sure it came up from Chicago or a suburb and was delivered to Zion, about 10 minutes north of me.

Is the $20+ more per sheet compared to MDF worth the weight difference?

It may not be totally worth the weight difference, but Its also supposed to be much easier on your tools. Thats whats really makes it worth it to me. Plus I feel it is much easier to work with as well.

To me it was MORE than worth the extra $$$. Box is 8.5^3 net, double baffle, window bracing, and 45's in the corners. I can easily lift/move it by myself. MDF would give me a workout....

And x2 on the easier to work with and easier on your tools.

If it makes less dust, I'm in. I hate the fact that I have to vacuum after ever 2-3 cuts and then spend 2 days cleaning my garage after working with MDF.

Definitely much less dust. More than the BB I've used, but still way less than standard MDF.

Trupan is the bomb, I used it for my 15" L7 box, and its lighter than my 12" box. Its expensive tho, 35 compared to 25MDF.
