Since the spindle kit is one our best selling items, we felt it merited a blog post to explain the increase in our price from $10 to $20. Our wholesale costs rose dramatically these past few months due to (we've been told) the price of steel. We'd like to offer a few options:
1) Our original threaded/tapped spindle kit which is great for saving lovely old doorknobs on a threaded spindle. See our blog post all about how to fix antique doorknobs here. These are still our favorite option, but the cost is higher.
2) We have started carrying a less expensive reproduction straight tapped spindle kit. These will function the exact same as our threaded/tapped spindles once your knobs are mounted. Getting them on, however, might be more difficult depending on your set. These spindles do not have any threads so if you're using them with a threaded doorknob where the threads are damaged, you may have to file out the remaining threads to get this spindle to work.
3) Threaded spindles (thread 16, thread 18, and thread 20) which work if your threads are still in good shape however you will need to know the thread size in your knob. Our wholesale on these spindles has not gone up so the prices remain much lower.
Thanks for your patience while we've gotten this sorted out. Please keep us posted on how best to help you our with your projects.
