I posted a couple of days ago that I got a new to me Meddings cold saw.
I have done some digging and I believe it is rebadged Record TL300 saw made by IMET.
I can't find the TL300 on their website anymore but it looks like they still do a Record 350 saw https://www.imetsaws.com/en/022301 and a Perfect 300 https://www.imetsaws.com/en/012301 which are similar.
So far, I changed the gearbox oil (must have been in there for YEARS) as it was very dark and had some lumps inside of it.
I replaced the oil with some EP90 oil I still had in the garage (think I bought it for my Ford Ranger diff at some point).
I also cleaned out the old suds tank which was probably NEVER cleaned before.
It was not a fun job.
I then rigged it up to a vfd for a little test run.
Unfortunately, the motor is a dual-speed three phase 400v motor so I ran it on the fastest setting on the saw (position 2 on the switch) being supplied by a 240v 3 phase supply from the VFD.
The VFD was set at 29hz and as far as I understand the motor will run at two thirds the speed it would have done if it was connected to a 400v supply.
This is an interesting article to read if you would like to know more: https://inverterdrive.com/howto/240V-Supply-to-a-400V-AC-Motor/
Unfortunately, the saw did not make much headway on the piece of angle iron I tried for a test cut. The motor did not stall or slowed down on the cut but there was not much happening.
In my limited cold saw experience (none) I summarised that the blade is probably very dull.
This is the blade that was fitted to the saw
I also had another used blade that was in the cabinet (also dull).
I looked online for a replacement and it seems like they start from about £60 up to £200 per blade, so not exactly cheap as chips.
I contacted a few blade sharpening companies and www.addisonsaws.co.uk came back with a very competitive quote. Both blades sharpened and couriered for less than the price of a new blade so I sent them away this afternoon.
In the meantime, I emailed Meddings asking for some information and Emma from Meddings very kindly sent me some info they had on the saw which I will post in the next post.
She also included a Meddings oil/lubrication document.
