wondering why not purchase a couple of cheap electric frying pans and a normal 2 ton press purchase some food grade square tubing 1/4 or 1/2 inch thickness now be it 4x4 or 3x3 or 2 x 2
take the power end of frying pan cut it out, so it fits inside diameter of square tubing
now you got the power end of frying pan or heating rod cut one side of square tubing half way and other side leaving possible 1/2 inch or inch or maybe right threw this allows the heating rod on top as its pressed down to move down as well
now you you got heat coming from both sides the lower heat element / table that is inside and is stationary
the frying pan has holes ? possible screen in it so that the oil as its pressed pours out ???

well the problem I encountered with the plates, is they are not milled perfectly to the size of the coil, which is hard becuase the coils vary in size themselves, so there is a bit of a air in the milled out area, the coils are loose inside, they do have a set screw so they don't fall out. but in actuality the coils only touch the plate in a few areas on the inside which makes it heating up through conduction difficult. so it is heating up by heating the air in the gap and that heat transfers to the plate. This was my experience with these plates and the e nail as the heating device. This is why I have scraped that route and i am looking into probes, so I can drill a hole the size of the probe and have a better fit and heat more accurately. In the conversation I had with them, they said "You'll need to build a reference chart for your individual PID to know what to set it on" basically you set it to 300 on the pid and it will be 150 on the plates.

We already switched to 4mm pockets instead of 5mm to allow for better thermal transfer from coil to platens for exactly the reasons you mention. c'est la vie

he has hand clamp like yours no plates

I wonder how long it will last then, When I use the clamp I got great results as well But it only lasted about 8 to 10 clamps lol. Maybe with this new one I got, like yours, it will be able to withstand the force.

I really hope I don't break another one so soon though lol. If I do, back to body weight I go.

Does standing on it really work? I feel like I would break it lol , maybe I am fatter than others :)

Oh yes it works pretty damn well I'd say. I'm 6'2 205lbs (210lbs now with the holidays coming lol) and no problems whatsoever. I know @hyroot I believe is 230lbs and has no problems as well.

When I stand on it, I use one foot and keep the other in the air or put it on top of the other one. Works like a charm lol. The 600lb clamp deff makes a difference I will say, I mean it is 3x the lb power lol.

Has anyone tried this with a lab press? Theyusually have top and bottom 6x6 heated steal platens that go between 150f and 500f and incorporate a 12 ton hydraulic clamp. With the math equation twitch provided thats 733 pounds per square inch.

SMART!
Carver Auto Series automatic hydraulic laboratory presses feature an enhanced "NE" digital control system. Offering 15 to 48 tons of clamping force (minimum 1,000 lbs). Work area of 6" x 6" to 18" x 18" platens. These benchtop presses are typically used in quality control, research and development for test sample preparations, destructive testing, molding, laminating and fluid extraction.

The new "NE" controls feature full touch screen interface with a proximity switch for adjustable slowdown position. Platen heat is controlled through the PLC on heated models and selection for auto reheat at end of cycle is provided. Platen temperature values may be entered in degrees Fahrenheit or Celsius and the display can easily be switched between the two units. Either force or temperature mode may be chosen per segment. Clamp force values may be entered in pounds, kilograms, US tons or metric tons and the display can easily be switched between units.

Carver Auto Series Presses also have two hand "anti-tie-down" close buttons and an interlocked safety enclosure with hinged door are provided for operator safety. This programmable control system has storage capacity of 10 recipes, each segmented recipe is capable of 20 programmable setpoints of: clamp force, cure time, platen temperature and bump (automatic bump sequence may be programmed in any or all segments). A self-contained 1/4 HP hydraulic unit. See below table for press specifications.

Yeah brand new they are extremely expensive. Used ones are closer to $3000 which makes them expensive for making your own rosin but for people in the industry doing it all day it maybe worth. Same company joe dank mentioned makes a non automated one with hand crank similiar to a jack for 2995.00 with the dual plates

heatpress.com is another company that has top and bottom heated plates 6x9 i think is their smallest but they can have you a 6ton unit with those plates for just under 5k... If anyone is interested in that I can pm you the rep's info
