OK,
First the bottom line:
The current DIY McLux heads and current DIY 1x123 powertails are both out of tolerance to the extent that they have an interference fit with each other. The tapped hole in the DIY heads is undersized and the threaded male section of the 1x123 powertail is oversized. These two parts can concievably fit with enough lubrication and cycling on and off to wear away the interfering metal but this solution sucks and it is possible to have the parts gall.
The only conflict I am just now aware of is with the two mentioned parts and the McLux head will fit the SF bodies as well the other sized and older power tails. The new 1x123 power tail will also fit the old McLux heads as well as SF heads.
I just discovered this incompatibility last night while doing a build for a CPFer of parts he bought from Wayne's store.
I could go into the background of how this incompatibility issue got past us due to different parts arriving at different times and some parts being rejected in lot and then replacements showing up even later on down the road. Suffice it to say, we didn't catch this one combination that just doesn't cut it! Understand that in a real professional and commercial environment, Go-NoGo gauges are made for QC of issues such as these. Our go-nogo gauges are other similar parts with out knowing where in the tolerance range they might be.
The solution we have determined is to take these latest DIY heads and re tap them, each and every one. The inventory that Wayne still has will be re tapped by yours truly. I got off the phone with Wayne and we think the best solution is to send new heads out to all of you who have already bought heads and want an exchange made. If you can e-mail or contact Wayne about this, he can send you a new replacement along with postage and a box for returning your existing head. We will in turn take your existing head and re tap it and put it back in inventory for re sale.
Understand that it may be that not all heads need this and if you are using the head for a 5W mod where it will never be put on a McLux 1x123 power tail then it is a mute issue. Wayne is going to put some type of alert or notice up on his web site as well to alert folks to this issue. Since having his own PC crash along with his web sight wasn't enough for fun, we figured Wayne would welcome an additional McLux challenge. /ubbthreads/images/graemlins/grin.gif
Wayne will come along here and flesh out the exchange program better in terms of the mechanics and of course you guys will likely have some input in how to proceed as well.
I think I'll let this post go as is for starters and then we can come up with viable solutions to specific requirements as they arise. Needless to say my apologies for myself along with the other stinkers and this was certainly not planned for. /ubbthreads/images/graemlins/frown.gif
