Hi Ash,
I also Live in London Ontario. I second the rubber/foam. I used some foam type practice hockey pucks under my Beaver 3100(massive and VERY heavy!) that worked well. Now I have one of the original black Excaliburs VS30" and vibration seems to be minimal. Keep your eyes on Kijiji in London area as they do come up fairly frequntly and quite reasonable. I picked one(19") up for my son in law for $100 recenty. Even came with the original manual/blades etc.
Most of the manuals for the original Sommerville Excaliburs can be found on vintagemachinery.com
Have had great success with Olson PGT(Precision Ground Teeth) blades. Can get them at Busy Bee Tools cheap or even better from R&D bandsaw www.Tufftooth.com and they will ship right to your door very reasonable
For dust collection I used a QSP Shopvac hooked up to a Dust Deputy cyclone which captures 99% of dust and keeps your vacuum filter CLEAN!!
If you want to discuss over a coffee at Tim Hortons, send me a private message and we can set it up. I live in South end of city.
Mike
