West System mini pumps .. ???
An old fridge is good for this, too.
"Bill Kreamer" wrote in message news:lurDh.6490$lo1.4384@trndny05... I just made an epoxy warming box. It maintains 78 degF in my unheated hallway (0 at night 15 in the day). Dim's: 2'H x 1'W x 4'L; the walls are 1/4" ply w/ 1"x2" pieces at the corners, put together with short drywall screws. I insulated the insides with 1" foil faced foam. There is a single centered inside shelf (1' off the floor). I cut (2) 4" x 8" holes of the shelf, one near each end. I mounted a 50W bulb under the shelf hole at the left end, and isolated the bulb into its own little "room" by a mounting a divider extending from the underside of the shelf downward, leaving a 4" opening at the bottom for air flow. Natural convection circulates the warmed air. -Bill "Jim Conlin" wrote in message ... I try to keep my epoxy jugs at 70 degrees or better. The warmer it is, the easier it is to mix and the more quickly it wets out glass. A heat lamp does the trick. "surftom" wrote in message oups.com... Could be - I keep the epoxy in my basement and it's cool (but not COLD) down there On Feb 20, 6:53 pm, "Jim Conlin" wrote: I find that 'burping' epoxy pumps are related to the resin being too cold. "surftom" wrote in message ups.com... I sometimes find that they seem to have air caught in them. Pump down. - cover the nozzle tip with finger then slowly release the pump plunger - repeat if necessary - usually work in 1 to 2 tries and pumps normally after that. I find that the need this treatement after sitting around for a long time T On Feb 18, 11:50 am, "NE Sailboat" wrote: I bought West System mini pump at West Marine last spring. Now ??
