    GD&T question on position

    Is this valid? I don't think it is valid since it's not a feature of size would replace it with a perpendicular with datum A or a flatness instead but I don't have enough experience with GD&T.

    Guideline or formula on slack to remove timing belts off of pulleys

    Is there a guideline or formula on the amount of center to center distance to reduce in order to remove a timing belt off of pulleys? I'd normally do guess but there's has to be a better way to calculate this.

    Gas Spring Calculation Help

    Trying to learn about gas springs and I'm not seeing how to get this angle for a gas spring angle to sum the moments at the hinge by the gas spring force. No issue with it flat but say as an example ie. its is rotate at 10° then how is this angle calculated to sum the moments? Would appreciate...

    Material to simulate frozen flesh/meat for cutting

    This is just a concept build to test feasibility, it requires a lot more time or resources to make an finalized machine.

    Material to simulate frozen flesh/meat for cutting

    Why not just use meat, cause organic material that get into cracks, holes, etc.. will cause bacteria growth and stinks. Just need to have something to test without having a big cleanup and washdown.

    Material to simulate frozen flesh/meat for cutting

    Is there something out there that can simulate frozen flesh or meat for cutting that is inorganic, something that doesn't stink or cause bacteria growth? Need to run it thru a deli meat slicer. I was thinking about using foam sponges and freezing it into an ice block but was thinking there's...

    Ice block with uniform size in a chest freezer

    I need to make an 8.00”x16.00”x2.70” ice block and need to control the ~9% expansion so that the ice block is a uniform as possible with a standard chest freezer. Using a stainless container as a mold with the top open and an Aluminum weight to hold it down, will make a silicone liner so that...

I'm using DB Browser for SQLite and not sure which tables defines whole wizard...

    Polycarbonate with wax/paraffin, oils, and food coloring

    Is Polycarbonate compatible with wax/paraffin oils and food coloring. I see some candle wax mold made of Polycarbonate that is sold but doesn't the aromatic oils and food colors degrade the Polycarbonate? I would think it would cause stress fractures or something.

    What this shoulder/thumb nut is called?

    The barrel nut is similar but the head diameter is too small, probably specific to spreading the load on the plastic. Don't suppose anyone know where to get something close to this, threads are M5 the barrel is 8mm OD x 7mm with overall head OD of 38mm?

    What this shoulder/thumb nut is called?

    Anyone know what these are called, they're used for mounting plastic panels so the threads don't make contact with the plastic hole? It's basically shoulder screw with internal threads. I'm hoping these are off the shelf parts.
