This lamp harp is welded to the lamp so cannot be easily replaced. The screw for the shade was welded on and broke off. Any suggestions for how to repair? I've tried various glues with poor results. I don't own a welder but willing to buy a basic one if there's a good chance of success. Always willing to buy a tool and learn a new skill when appropriate. I'm trying to think of some mechanical way to do this with brackets or other hardware. Drawing a blank.
Your first consideration has to be evaluating the value of the lamp. There are various factors that would need to enter into the decision equation as to whether to repair or replace:
- Sentimental attachment
- Part of a set of lamps
- Cost of repair
- Replacement cost
If you land on the side of repair then I can see a number of possible options.
- Take the whole lamp to a lamp repair shop and get experienced parts replacement advice or leave it with them to repair.
- Take the lamp and broken off bolt to a machine shop that has a small TIG welder and get them to weld the bolt (or a replacement bolt) onto the harp. I do not recommend doing this as a first time DIY welder as welding thin small parts is an art that requires considerable experience and the necessary equipment would outstrip the replacement cost for most lamps.
- Consider the lamp socket holder itself on the lamp to see if it is removable. If it is it may be possible to purchase another type of replacement lamp socket assembly without the welded on harp. There are harp lower saddles that mount under the lamp socket and clamp into place. Then a new lamp harp can be clipped to the saddle with ease. The picture below shows what this would look like.
- If you have any metal working tools it may be possible to craft up a pair of small metal blocks that you could clamp to top of the harp with two screws through one half and threaded into the other half. A new shade retainer bolt could be a stud that fits down into a threaded hole into top of one half of clamped on blocks.
Per the accepted answer above, here is a picture of the old and new harps with their respective bases. I originally saw the old harp as "welded to the lamp" but in fact it was welded to its own base that was attached to the lamp in the usual way, and it was easily replaced as shown here.
I was excited to develop my non-existent brazing skills as suggested in another answer, but I'll have to leave that to another time.
