In this post I want to talk about another replacement clamp that I purchased from Mike over at www.mikesworkshop.com. Mike is the guy I buy my Flying Dutchman blades from. On his web site in the accessories page he has these quick release levers for the Hegner scroll saw. The screw size and thread pattern is the same as the clamps for the DeWalt and the Excalibur. They are 6.95 per lever plus shipping.
One point to carefully consider with this type of clamp replacement is that you have considerable more leverage to tighten the clamp. This can be a problem. You don't want to over tighten the clamp and break the clamp holders. I have talked to people who have had this happen. There is no need to apply extra force. If the blade is slipping out of the clamps it's not because you are not clamping hard enough. Something else is wrong. DO NOT brute force these clamps.
This issue is some what random from my experience. With this new set the bottom clamp has the problem but the one I installed in the upper clamp does not. I suspect there are a few causes for this including where the clamp contacts the blade at install and how flat the end of the screw is. I'm going to spend some time trying to find a way to minimize this when I get time. Actually aside from being a minor inconvenience this damage has never caused me to have to replace the blade early or caused any premature breakage. It's not a deal breaker for me.
If you have been looking for a better solution to the standard clamps these might be a good choice. You almost have to try them for yourself to make a final decision but for under $20 it's not a huge cost if they don't work out.
This is not a paid endorsement. I purchased the clamps myself and have had no discussion with Mikes Workshop about this review. www.mikesworkshop.com
