Large Sebenza/Insingo FULL BACK SPACERS...

Made a couple of additional changes to the Lg 21 back spacer design.

One change is functional and the second serves both function and aesthetics.

Based on the success of the front cusp capturing the blade stop lug on my Inkosi back spacer design I incorporated this cusp capture on the Lg 21 spacer. The pivot end of the spacer no longer just rests atop the blade stop round spacer... it partially captures that blade stop round spacer.

The second change is the addition of gimping to the front end on the spacers spine...

I'm machining a run of eight of these new spacers in carbon fiber and will post up when I have them ready to place in the Marketplace.

I can’t tell you how excited I am for you to do the same for the small! These look so awesome I’m tempted to buy a large just so I need one of these.

I'm glad the idea of the capture point worked out, it just made a lot of sense. This will also help not having to get the thickness spot on to the 0.0005". A lot of the original design does rely on friction if the hole fit isn't super snug. And I like the bevels on the spine, I put all mine in manually.... total pain. Dig how this project has evolved over time, thanks for continuing improvement.

I believe we will have to modify the small for the next run of Ti/Timas!

I do intend to port the capture cusp solution over to the Small 21 back spacer.

These back spacers have me lamenting my inability to machine Ti/Timascus and IF/WHEN you decide on making another run of your little jewels I will gladly provide you the files.

I appreciate that!

It is never too late to start cutting metal or investing in new equipment (nudge). I get many messages about Ti spacers for the large. I know that I will likely never make them, so you would definitely make a lot of people happy.
 
My current CNC employs a high speed spindle which can't be slowed sufficiently to achieve proper feeds and speeds for metals.

To acquire say... a Tormach 770M or 1100M CNC mill... you are looking at $14,000 for the 770M and $18,000 for the 1100M for a basic starter setup and tooling. Those funds just are not available.

IF I had the ability I'd be milling Ti/Timascus spacers almost exclusively!

Oh yes, I know I've tried to get you to start in the past. Only kidding of course, certainly not a small investment.

Some other metals out there would be cool to try as well. But I always seem to come back to the ti/timas.
 
OK... I have machined up a small run of eight (8) carbon fiber back spacers in this NEW design.

First off these are the capture cusp design that captures a portion of the blade stop spacer. They no longer just rest atop the blade stop back spacer as they did in a former design. These incorporate gimping at the blade end and also have chamfered edges. These also eliminate the use of the stock rear round metal back spacer... using just the body pin and body screw. The $5 CRK stepped lanyard pin is required for install.

Machined from Fibersmith's LVA (Low Void Aerospace) 2x2 6k plain weave Carbon Fiber.

This is the cogged version. A gimped smooth version will also be machined.

In the near future I will hopefully be able to offer back spacers in a luxury carbon fiber product made by a gentleman in the Netherlands. It's high end and also has a high end price and costly shipping... however I do hope to test the waters with these luxury carbon fiber products.

I obviously missed this most recent drop. Do you plan on making another batch soon? Do you do custom orders?

Negative on the custom orders. These back spacers require several machine setups and special jigs. Takes time to setup and that time cannot be cost adjusted for machining just one or two back spacers at a time. They only make fiscal sense to machine batch runs.

I just checked and I do have a small number of Large 21 carbon fiber back spacers sitting on the finish bench... looks like 5 available at a quick glance.
 
YUP!

Have several carbon fiber back spacers for the Large 21 sitting on the finish bench.
 
Hi, I’d love a full back spacer, in black Micarta for a large Seb 21. If you’re making anymore please can I buy one from you.
Many thanks, Craig.

Hi Craig...

No plans to machine Micarta Large 21 back spacers at this time. Can't even guesstimate if or when that might happen.
