Thread: Updated (2019) Parts List for Automating Master Caster

  1. #1

    Updated (2019) Parts List for Automating Master Caster

    I'm hoping to get an updated McMaster Carr parts list for the lastest (as of 2019) Hatch/Wyman design for automating my Master Caster. ***Note, my goal is purchase a Hatch panel to run the MC but in the meantime I'd like to purchase the parts that I can from McMaster Carr. (Yes, I know many/all of these parts are available directly from Hatch but I'm in a situation that I can get "free to me" parts from McMaster Carr.)

    I've read and re-read Cast Boolits posts for automating the Master Caster and want to make sure I'm getting correct parts. I want to use the double action air cylinder in lieu of the spring return design.

    Listed below is the original shopping list from the Wyman build... I know I don't need the first part (hand operated lever control valve) and one or more of the air cylinders are incorrect but which of these parts could I order that would be useful? Also, does McMaster Carr sell the air switches need for automation?


    1 – 3368K31, hand operated lever control valve, spring return, exhaust center, $64.02
    1 – 8812K32, air regulator w/ gauge, $29.43
    2 – 5779K159, tube swivel,1/4 MIPS-3/8” tube, $4.50ea
    1 – 62005K333, flow control valve, 3/8-3/8” tube, $27.70
    10 – 5112K65, nylon tubing, 3/8” OD, $0.77/ft
    1 – 6498K145, SST air cylinder, 3/4” bore-5” stroke, spring return, nose mount, $30.15
    1 – 6071K12, forged clevis end, 1/4-28, $4.98
    1 – 6498K195, SST air cylinder, 3/4” bore-1/2” stroke, spring return, nose mount, $18.02
    1 – 6498K42, rod clevis for 3/4" bore, $4.08
    2 – 5779K157, tube swivel, 1/8" MIPS-3/8” tube, $5.10ea
    1 – 8975K483, 6061 aluminum bar, 5/8 x 1-1/4 x 12” long, $9.31 (for nose mount cylinders, stand off and pivot)
    1 – 4501K72, 1/4" SCH40 brass pipe, 12”L, $8.88 (cut to 2.125” for 1/2” stroke cylinder stand off)
    1 – 91251A370, 5/16-24 x 3” SHCS, $7.02 (for mounting 1/2” stroke cylinder to lead valve)
    2 – 97345A578, SST 5/16 x 1/2”L shoulder x Ό-20 shoulder screws, $3.54ea (for 5” stroke cylinder pivot)
    1 – 9664K19, cut to length extension spring, .375” OD x .035” wire, $3.56 (cut to 4” for mold return spring)

    Thanks in advance for any advice.

    I am pretty sure those are the parts.
    Not positive on the fittings above so you need to check them

    Movement air cylinder was switch to double acting.
    So you will need another fitting or two because of that.
