    For my front hinge I bonded some 3/8 diameter threaded rod ends into the front clam for the pivot points. Holes were drilled very carefully into the "fangs" (as others have called them) of the front clam. The rod ends were then inserted using an alignment rod to keep them in line with each...

    We have had some rainy weekends so we have not gone camping and I have found some time to spend in my shop. Finished and installed my rear wheel wells and closeout panels for beside the engine. I will spray bedliner on the wheel wells and will either polish or paint the close out panels in...

    Haven't posted an update in a while because there has not been much progress on the build unfortunately. My workplace has me traveling every other week and spending a week at a time away from home at our Greenville, SC sister company. This time away from home has cut my spare time down to...

    Joel’s SL-C Build Thread

    All I can say is WOW! Nice work Joel, I love all the information you will have at your fingertips and how relatively simple the system components are. All the programming certainly was not simple and was time consuming but I can see that you enjoyed it. Excellent work and I cannot wait to see...

    Alan, I printed the parts on a Stratasys MC250 FDM type machine using ABS Plus material. It is a plastic that is similar to nylon only a little stronger. Most stereo lithography and poly jet parts are sensitive to UV light since they are cured with UV light. That is not an issue with FDM (fused...

    Joel, Thank you for the compliments and feedback. My plan on the bezels is to prime the 3D printed parts with epoxy primer to seal the plastic and then to use body filler and polyester primer to smooth everything out. As long as the 3D printed material is sealed (it is very porous right off...

    Took yesterday off of work to spend some time in my shop and de-stress. Have made some good progress over the past few months on my way to having the car road worthy late this summer for testing and tuning. This fall I will then take it all apart again for bodywork, paint, and interior...

    Restarting my SLC project in West Texas

    Great work Hector!! Congrats to your son on whichever school he chooses. It is great to see your successful leather application on your dash. I plan to do the same (except I plan to purchase a leather sewing machine as I am doing my own seat covers as well) and am very scared about getting...

    Jeff, No, you cannot backdrive these actuators. The utilize an ACME screw which cannot be backdriven (square shaped threads) as well as there is a worm gear on the motor driving the screw which will also prevents them from being backdriven (to a degree). This "holding force" of the actuator...

    Since I have the doors installed the next step was to actuate them. Credit for my electric door design goes to Allan for his original design and to Mesa for his mods for the gas strut design on his doors. I basically replaced the gas struts in Mesa's design with electrical actuators from...

    Factory Photos from RCR

    When I toured the factory some years back I remember seeing a tag on the jet engine stating something about a "sidecar racing propulsion project";) Fran was very mum about the details. Skunkworks stuff.

    Has anyone else noticed that the gap between the driver side door and the rear clam is not consistent at the top? I have a very consistent gap from the bottom until you get up to the point where the door and clam curve to horizontal at the roof then it opens up about 3/16". I can easily fix...

    Update: I have finally been finding regular time each week on Wednesday night while the darling wife is teaching religious education at Church to work on the SLC. I recently finished my nephews truck. As is usually the case, more tasks were added and we sprayed in a bedliner. it is not...

    Stephan, Glad the design worked out for you. The pieces turned out beautiful, excellent work on your part! Where did you get your throttle cable? I like the termination on yours better than what I did for mine.

    LSA SLC Build Log

    Rob, Here is another option for you. I purchased the mounting brackets from Pantera Electronics and tig welded a bar of aluminum to them. I was able to utilize two existing tapped holes on the SL-C uprights to mount the bracket to. Sorry, I do not have a print either, fabbed it up on the fly...

    Once again life has gotten "in the way" of progress on the SLC. Trying to commit one night a week to working on it again soon. In the meantime, my brother and I built a paint booth in my shop using professional quality fans (11,000 CFM total) and paint booth filters so that I can paint his...

    Had a request for my throttle pedal cable linkage design so posting it up here for all to share. There is a design for a 3D printed version and one machined from aluminum. All the required bronze bushings, fasteners, cable, etc. are spec'ed out on the BOM of the assembly prints for each version.

    Mark, I purchased my rear tow eyes from McMaster Carr. They are female threaded lifting eyes that I painted red. They are only available in course threads so I had to change out the pivot fasteners. And yes, tie down points for trailering are what I “plan” to use them for, hopefully nothing else.

    Quick updates on progress: 1) rear wheel alignment in the wheel wells has been addressed via plan "B" The adapters I made moved the wheels to far outboard and they were going to interfere with the bodywork during extreme suspension travel. Plan "B" was to install spacers in place of all the...
