Rather than make my own dust collector for my Hegner I bit the bullet for $85 including shipping and bought the Hegner dust collector. It came around noon and I installed it this afternoon. After receiving it the package was just a padded envelope. Holy smokes, I expected something more substantial. I mounted the lower collector. I had removed the pull down clamp guard deeming it unnecessary but had to reinstall it. It does channel the sawdust down toward the collector. I wondered how this flimsy thing was going to work. The topside vacuum bracket will be cut down. The original idea is to clamp the bracket over the blade arm and the extra arm for the hold down with the vacuum line on the left of the blade. I wanted the vacuum tube on the right side. I don't use the hold down and had removed the arm so I just bolted the bracket on the right using the mounting holes for the arm. Then going from a 2 1/2" collection hose down to 1 1/4" on the collector was a little problem. I could find no PVC or ABS fittings that would make the reduction. Thanks to a helpful man at the ACE hardware store he came up with a fitting that worked. It is not something from the plumbing department but it worked. That little plastic fitting was 10 bucks. It's ok as it works. Turning on the HF dust collector the lower vacuum has plenty of suction. The upper is very weak . However, when cutting with the nozzle almost on the pattern it actually does pick up the fine sawdust. After uing it for a whild I will be able to determine how well I like it. Te upper can always be returned to the bellows for blowing.
