UJK Parf Dust Port

Functionally, this would be a 4. If it's connected as intended, extraction of dust would actually be a 5, but chip extraction is more like a 3 due to clearance issues. The problem is that the fingers that clip onto the guide bar (which is easily a 6!) are all but impossible to avoid breaking, even with great care. Mine broke on the second use. I worked up an improvised retention method, but candidly either the design or the materials chosen really need reconsideration. This is the only issue with the most excellent Part Guide Mk 2 kit.

I just purchased the Parf System over the holidays and created some folding work tops. The system is fantastic, but one of the the arms of this Vacuum Port broke on its first use. The arm looked bowed in to begin with so it must have had more stress when attaching. However I think it’s a poor design to have those thin arms and I hope this port is redesigned.

The plastic "fingers" are very fragile. I followed the instructions on Peter Parfitt's Youtube video to put this one, worked great once installed. However, removing it is very tricky, if you bend the fingers even a tiny bit too much, they break. Kudos to TSO's great support, who quickly sent me a replacement, but unfortunately that one broke attempting to remove it VERY carefully. I even heated it up first to make the plastic a bit more flexible. I guess I'll make a shop-made one as shown in Peter Parfitt's video.

I purchased my Parf system before this dust port became available. Having done the drilling without it and now with it I can unequivocally say it is worth every penny in making the drilling process faster. It clears shavings quickly and thoroughly.

one of the side clip retainers fractured off when attempting to attach it to my drill guide. When seated snugly onto my drill guide with a rubber band, debris recovery is great..
