FYI


If you raise your temps too quickly you will hit the glass transition temp of your epoxy, ruing the structural integrity of the entire composite.

You want to "chase" this temperature point with your ramps...

DBS, you must have got your blankets right before a price adjustment. I tried everything to get the prices down and no one budged. I wish it only cost $220! Last summer ( IIRC) I was able to get MEI to honor a 2-month old quote and I got a few of us here a killer deal. I think the prices went up so...

Lenox Bi-Metal FTW.


I'd have to go digging around to find one for the exact model, but these last me 4 pairs, start to finish. I used to get them through a commercial supplier, sucks that I no longer have that connection.

Prolly weighs in over 1000lbs. Once I get a blanket I will need another dual controller. 15" wide 15" high 8' inside length. A little high but we can fill the gap. Some local guys did the welding. They have a substantial custom metal fab shop. They make hotrods also. Mostly heavy mig weld...

Damn, that thing sould look so much better parked in my garage then my car!



You still need that new controller?

you will be disapointed with al. its pretty expensive. imo you dont need that track but its your press. not mine. Keep in mind this post is from a 15-year old who hasn't built a ski yet. Read his journal, it is very "interesting". Badner, stop dumping on others. You refuse to take advice ...

You want around 60% fibers to 40% matrix (epoxy). This number varies with material and resin/epoxy.

Epoxy sucks as a structural material, in an ideal layup your loads are carried by the fibers.



Not going to get into the PSI thing again, i feel like we have been there before...

Turns out the outlet is actually 250V 50A which, from what i have read means that there are two hot lines and a ground running to it (so prob. 240V). I know that you can run a heating element off this set up (from what i have read) but was wondering if anyone knew how it would affect the wiring to ...

I was told currently 3 phase 220, but machine European and can be easily wired to single face with simple switch replacement . Not sure how much it's true I am not electrician. electrical fail. 3 phase is 3 phase, unless you run it through a converter. you can usually go 120-->220 and vice versa by...

Too much stiffness (i.e. adding supports and welds everywhere) can be just as bad as not enough. If you over constrain your press it can not flex at all.... It looks like you used some angle iron and some old pallet racks (industrial shelving). You are going to hurt someone with that setup, take a s...

Have you ran the numbers? Pressure is a dangerous thing. Yes the bolts are going through 4 holes, but there is ONE shear point - in between the two bars. That's where they would fail. Hose pressure times surface area, divided by the number of bolts (16? or is the back part welded) Also a good point...

Well I re-drilled all the holes last night to 3/8 and put grade 8 bolts in. I do realize that they are designed for tensile forces primarily but I don't think in this application there is nearly enough force being generated to shear them especially since each bolt is running through 4 holes. Is the...

DO NOT USE GRADE 8 BOLTS If a grade 8 bolt fails it snaps. Grade 8 bolts should not be used for an application where they are subjected to shearing forces. I don't ever remember coming across that while studying fastened joints. I'd look it up but my book is packed away somewhere. The guy who wrote...

I see what you mean. It works out cuz I could only find enough plastic for half a cat-track so ill prolly just go pick up some steel/aluminum tube at Lowe's for the cat-track. @twizzstyle I was thinking the same thing about the rubber. Shop around, trust me. Try onlinemetals.com as a start, dependi...
