I was cutting some hard Manzanita burl on my Delta 14” saw and the blade got stuck. I got it loose and finished the cut. Then I went to make the next cut, the table was not level. As I tried to level it, the table came loose, as in off in my hands!! Both trunnions had broken along the thin top. Anybody else had this happen? Of course it was 5:00 on Friday and I have to wait until Monday to talk to a replacement parts place.

O man, robert I am so sorry! Check out,

http://www.ereplacementparts.com/delta-band-saw-parts-c-3275_3481.html

They usually have what you need! The parts are the same factory parts, just through a different supplier. Strangely enough. I actually saved money going through this site for my Rigid Saw repair then going through Rigid!

I hope this helps. I hope to have power to my shop soon, then you can come over and use my bandsaw when yours is down, or if you just want to use it!! Door will be open to you anytime brother, (once I get all these trenches filled:) )

Never had that happen. Makes you wonder if there had been arepair made to that trunnion in the past. I can’t imagine that saw producing enough force from a blade binding to cause the damage. Hope you get it going. JB

Nate, thanks for the offer. I can take stuff over to Pete Wilcox and use his bigger Grizzly, but mainly I was frustrated that this broke. It was a thin cast piece-both trunnions are broken. Not built to last?? I have other things to do that don’t need the band saw, but I was ready to cut the edges of miter keys that need to be trimmed on 11 boxes. A sharp little hand saw will do that. Only 130 of them!!
I found two places that have the part, but not open till Monday
Cabmaker, I got the saw new about 8 years ago. I haven’t abused it, but I have grabbed the table top top move the saw. It could be the stress of twisting that did the damage. Didn’t know the trunnions were so thin.

Dang Robert, I’m sorry to hear that! It always happens right before a big weekend project. I’m curious as to whether the trunions were cast iron or aluminum?

Andy, they are pretty light weight. I am not a metal person. They broke into a couple of pieces on each side. They were very thin where the bolts slid as the table tilted. The edge of each piece looks like it was cast as one piece.
Hopefully I will get some more ordered Monday and they won’t have to come from China like parts for my HF lathe!

The history of your bandsaw may have included the table
or entire saw being dropped or tipped over.

The trunnions are likely “pot metal” a cheap, but functional
alloy.

Loren, I bought the saw new. Haven’t dropped it or knocked it over. Just the possible stress of moving the saw(on wheels) by grabbing the table. I would agree this is cheap metal. Haven’t heard the term ‘pop metal’ for a while. It is what we used to see from Japanese made toys when I was young. In the 50’s! Hope the new ones are better. One reference took me to Powermatic replacement parts that are supposed to work. I plan to call and make sure before ordering. This has been a good saw. I am planning to get a Rikon soon for the resaw capacity and keep this one for cutting curves.

According to my research it is a common problem with that design of bandsaws. Not just the delta brand but most of the clones too. I’m not 100% sure but i think any of the clone brands will fit the delta like General, Grizzly as well as Powermatic. I was about to order some from Grizzly for my old AMT delta clone.

For what it cost and the 3/4 horse motor it has done well. I use woodslicer blades and get good cuts. Powermatic isn’t in my price range for what I do. I would hope their replacement parts are better than what is on the Delta.
Moron, often I am the problem!! Here though the metal seems very poor. WHO KNEW? The table seems the best place to grab the saw to move it.

Those pot metal trunnions have been the same on the Deltas for over 60 years and are just fine as long as you do not abuse them. They were not designed to handle a lot of weight on the table, or to allow the table to be used as a lifting handle. The most common method of breaking is by people trying to transport a machine without first taking the table off. Fortunately, they are pretty cheap and are easy to replace.

Cheers,
Brad

MrUnix, thanks. I know better now. The table is pretty solid and heavy. I guess I did not expect such flimsy connections, even though I put it together. I have probably forgotten a lot of things over 8 years.
