    Acrylic WTC Cutting

    I have a 36" long piece of Cast Acrylic Tubing 104mm x 110mm and need to cut to length 29".
    Need the cut to be as true and flat as possible for the end caps to seal. Local machine shop wants $350 to cut!!
    I looked at a few you tube videos showing how to use a table saw but since I dont have one that is
    another $300 option. Any other ideas on how to cut this stuff without chipping or cracking the material?

    Wood cutting 12" chop saw will make a clean straight cut.

    I actually cut the 4" cast acrylic tube on a table saw with a 90tpi carbide blade by rollng over the table blade with the tube.
    Came out perfect not cracks, no chips and flatter than factory cut.
    WTC is just about done, I had to make custom o-rings 1mm larger than the factory supplied since the acrylic is a little thinner than the PVC tube they provided.
    Cant beat seeing the internals. Need to do a pressure check then try to figure out how to connect the x-tail to the 2 pushrods.

    Standard rotation on the saw blade, set height 1/8" higher than thickness of acrylic. The trick is to have a perfectly flat surface against the guide and to rotate the tube smoothly. It is also important to have a carbide blade with a higher tooth count no offset and staggered grind on the teeth,

    I am building an Arkmodel A212A U22 sub. I will post some photos when I can. My biggest complaint is the lack of support from the manufacturer and having to pay to get parts that were missing from the project kit. The supplied documentation is very limited.

    I know what it meas and is to bad for them because an unsatisfied costumer is not gonna buy again fro them so I don't understand these policies !!!.Is bad for business in a long term .
    I have a 212A type sense 2010 and is steel unfinished because of some Piston tank glitches unsolved no mater what I drayed .Now is dismantled and I use parts for another project .
    If You use the same system : 12V/TAE Piston tanks may be I can find an answer for my problems.
