- In this video I describe the parts of a Delta Rockwell Unisaw Jet Lock Fence and show how it is all put together. I also describe the rubber bushing that is prone to failure and a common problem with these old fences.
If you're in the US, the rubber bushing is available at the link below. I have no connection to the company. www.renovopart...
Great instructional video. Purchased my unisaw in the mid-80's from Delta in Quelph Canada. I wouldn't give up my Jet Lock Fence for any brand fence on the market today. Recently re-faced the fence with an aluminum extrusion on the blade side and a piece of melamine on the other. Squared it up to form a "box" modeled after the Biesemeyer. Works like a charm w/o a lot of expense and replaced the indicator with a piece of plastic with an etched line. Thanks again.
Thanks for your comment and tips for improving the Jet Lock fence.
@@ToolTalkCanada Just an observation when referring to the 9:30 segment where you mention eccentricity. The back part (away from you) of my fence moves ever so slightly toward the blade when tightening. I wonder if this is due to that eccentric movement. Thanks again
Excellent job! About the only addition I made was a 5/16" flat washer inside, on the side opposite the rubber bushing, to keep the pivoting part centered. The bushing is available from Renovo Parts. $15 part, $13 shipping (to So Cal). I've got an older 54" Biesemeyer on my other Unisaw, and I've also had very good performance from Vega Woodworking fence systems. But I must admit, with the replacement bushing, and the washer keeping things centered, this old Jet-Lock is a keeper. Again - Thanks for a quality presentation!
Thanks for watching and for taking the time to share your comments. Great tip on the flat washer to keep things centered!
Thank you for the very clear and informative video. Precisely what I was looking for. This fence system was also used on the 1973 Rockwell 34-338 Contractor Saw which I am restoring. The cam was initially clamping down on the front rail perfectly, but I felt something give and now the cam'ing action does not cause the internal lever to touch the front rail at all. I've been scratching my head how to take it apart and will be giving it another look after finding your video.
Thanks again! I was able to disassemble the fence and find the problem. I'm not sure how, but one of the sides of the "fork" at the tip of the internal "lever" piece that keeps the long tension rod that travels to the end of the fence centered on the lever piece had broken off. I believe the tension rod then slipped off the lever causing not only the rear tightening mechanism to not work, but the front rail grip no longer worked either. I was able to craft a hardwood splint and epoxy it to the side of the lever to fix the issue.
One tip I figured out for re-assembly of the unit was to install the large spring before inserting either the cam pin or lever pin. This allows you more room and you have to fight the spring less to get it in place.
Lastly, I'm not sure if the small spring inside the tension rod adjustment screw had been lost by a previous owner, however I did not find a spring inside of mine.
Follow up note, the epoxy did not hold, so I ended up drilling a small hole into the cast iron and inserting a brad nail as a guide to keep the tension rod on top of the lever.
Glad the video was helpful and I hope your repairs hold up.
Great video. Thank you
Has anyone found a Canadian source for the rubber bushing?
Helped me out so much. Thank you
Glad it helped!
Awesome video! Can you share details on how to adjust the fence? I have the same one but the front and back seem out of alignment making the feed not straight.
Great video and perfect for what I'm looking for. I am restoring a similar (slightly older) Jet Lock fence that came with a much older Unisaw. You mentioned that you had a source for the rubber bushing (which I also need) in the US. Since I'm in the US I would like to try your source and see if the shipping is any cheaper within the US. Can you please tell me what your source for the rubber bushing was?
The rubber bushing is available at www.renovoparts.com/904-08-021-4550-rubber-bushing-for-jet-lock-fence/ Sorry I didn't mention that in the video or description. I'll add it now. I'm glad the video was helpful and please post an update if you get the part.
Have a buddy with lathe spin up a couple of those bushings out of UHMW.
UHMW would be too hard. It has to be something resilient for the clamp mechanism to work.
