LT trunk latch repair

I currently have ordered the replacement latch for the K1200 trunk latch from LTtrunklatch.com. Currently the parts are being manufactured as we speak. I was hoping to find out what the new status for shipment is as the web page has a 4/20/10 message.

I have already followed the directions and removed the old latch and just waiting for the parts to install the new latch.

Thanks for a wonderful fix for poor design by BMW.

And worth the wait, I might add!!

Hey Evan - sounds like you need a valet, a body double, or a stand-in or sumbody?!!

Re: LT trunk latch repair

Hey Dick,

How are you guys doing? I hope you're good as gold over there! Miss y'all....You keeping up with Eddie B.? Last I spoke with him, he's building another hot rod.

OK guys, I tried putting up a bunch of IN-PROCESS pics of your product being manufactured and ran into hassles with online photo-hosting BS! I'll upload them to MY website space before dawn tomorrow and figure out how to get 'em posted up here....quite interesting and entertaining stuff, in MY opinion! Gotta go, finishing the last of this first 'partial batch' of 30 units....then sanding, vibratory deburring, priming, painting, boxing, and SHIPPING!!

It's coming, I promise ya! I'll open up the "ordering" section of the website within 1-2 days so I can get an idea of how many of each color to paint....

THANK Y'ALL (Texas slang for You All [a lot of French people order these] ) for your continued patience! SOON!! Gotta go...Thanks!

Re: LT trunk latch repair

I hope I don't get in trouble with the site administrators for posting these pics.

This is after the first operation that prepares the aluminum slabs for fixturing on the "tombstone" that is connected to the 4th axis rotary table. The rotary table axis allows machining of the backside of the handle (5 at a time), then is programmed to rotate 90 degrees so that milling, drilling, and tapping is accomplished on the sides of the parts. After the 1st operation of preparation:



Here are 2 slabs that have had a bunch of material removed:





Now, the third and final fixturing setup entails specially designed fixtures that clamp the slabs down. There is a 17/32" hole through the lock barrel region and one 17/64" hole on each side of the part. The pictures will show you how the parts are clamped:

















Now that the slabs are rigidly clamped, a milling cutter separates the parts and cuts the perimeter profile:



Followed by a cool "inverted" radius cutter to machine a radius on the UNDERSIDE of the handle:



Rough machining of the complex curved surface that matches the contour of the trunk body:



Final machining cut:



The surface is machined with a ball-end milling cutter that moves over in small (.020") increments to form the surface curvature. Here is the result before I sand that surface:



Pile of 30:



Next stop, Vibratory Deburring:

Re: LT trunk latch repair

And I thought you just waved your hands magically to make my replacement part last year. Very impressive. Thank you again for a great product.

Re: LT trunk latch repair

Thanks for the picutres. I really like seeing the process of how this kit is made. I am waiting for one of those finished units. I have already removed the latch and have it sitting on my workbench. Once the kit is here good by bunge cords.

Thanks for the updates/

Slight thread hi-jack.

Edit: damn fat fingers!! Anyway, wanted to say thank you for the pics, Evan. Very impressive!

I have Sunday breakfast with Vernon and Wally (Eddie's bros) pretty often - they're all fine. Eddie still lives in the hot rod 50s!!
