The design of the saw had several shortcoming which resulted in much sawdust in the workspace. So I've made further modifications to help reduce my dust exposure, which is starting to affect my health.</div> <div><br></div> <div><img src="cid:a0611041bbed2651a5910@[192.168.1.100].1.0"></div> <div><br></div> <div>The dust extraction duct on the right is original. The shroud which isolates the lower guides and new blade brushes from the lower wheel housing was a modification I made soon after getting the saw, although I've added another piece to join it to the top side of the wheel housing, so that its rigid enough to carry the new left hand blade brush.</div> <div><br></div> <div>The lower wheel housing had far too much open area which allowed dust to get out and around the shop, and there was no extraction port for the lower wheel housing. The sheet metal around the motor drive shaft, and the piece immediately below it, are new. The blade brushes and the new wheel brush, and associated mounts, are newly fabricated. The new 4' extraction outlet at the bottom left of the wheel housing is new. There now remains about 6 sq" of aperture where the footbrake lever protrudes through the housing, and there is quite a cross-sectional area where the band travels up the back side of the saw. The better shrouding of the lower housing and the new 4" lower outlet should result in quite a down-draft going against the blade as it rises in the rear housing. This should help to strip the fine dust from the blade before it reaches to top wheel. Well that's the theory anyhow.</div> <div><br></div> <div>You'll also notice that this saw is mounted on a set of Darnell piano castors for ease of moving around the shop.</div> <div><br></div> <div>Repainted the new additions last night, so its re-assembly time this morning, then I'm off tuning in the country for a week.</div> <div><br></div> <div>The newly rebuilt CF is seeing its first serious work in a regional eisteddfod, so I'm taking a few days to prepare it and to do several other local jobs.</div> <div><br></div> <div>Ron O.</div> <x-sigsep><pre>-- </pre></x-sigsep> <div><font face="Times New Roman" size="+1" color="#0000FF"><b>OVERS PIANOS - SYDNEY</b></font></div> <div><font color="#000000"><i>   </i></font><font color="#0000FF"><i>Grand Piano Manufacturers</i></font><font color="#000000"><br> _______________________</font></div> <div><font size="-2" color="#000000"><br> </font><font color="#000000">Web http://overspianos.com.au</font></div> <div><font color="#000000">mailto:ron@overspianos.com.au<br> _______________________</font></div> </body> </html>
