I am now the proud but perplexed owner of a nice Jet 2000, 14" power hacksaw. I would estimate that it is about 20 years old. It is very well built and can handle stock up to 8" in diameter with hydraulic up/down feed and coolant pump.
However, the vise screw has stripped threads. Actually the scew is still fine but the female threads in the nut, cast into a the long "tee nut" under the moveable jaw of the vice is stripped clean. Most seem to think it is acme threads but my old timer/mentor seems to think it is metric. It measures 1" diameter, LH, with a pitch of 6 or 6.5 tpi. Nothing like that in available in Acme taps.
I've been in contact with Jet and they have contacted Machine Tools Direct and inform me that this is a smaller version of the Jet-2500 and made by Murahashi (Heavy Industries). It seems like the machine is obsolite but I'm hoping to find a old parts source.
I could make a new sliding tee nut using available Acme long nut from Tacoma Screw Products and replace the scew with with standard 1" 5 tpi but this would provide slightly less clamping force as the vise jaws are drawn together. (I could live with that but---)
Does anyone else have this machine or any recomendations on replacement parts??
Thanks
Steve
