Woof! Another couple months pass by. Summer is always a busy time, all our kids are home for the summer, busier house, we take trips (went to Zion & Bryce NP this year), keeping everyone busy and happy becomes a full time job. So, slower with the projects in the shop itself. But, I did get around to going on the final portion of the main middle work area of the shop (tablesaw, jointer, router table, assembly table).
This final piece is a combo workbench, storage and also serves as an outfeed support. It's a piece that will provide nice smooth planar surface with the existing assembly bench and tablesaw top, but then also I want to include a matchfit grid for more all purpose clamp-ability as well as a ton of storage. Here's a basic model:

Pretty basic but there's more going on than appears:
- It's super wide - 54"!
- Not a ton of room for internal structure. It's built with a couple of braces but still only plywood as the case, and no bottom bracing.
- I want to make the lower shelf an independent sliding platform that is sized to eventually house a Onefinity CNC that I plan to purchase in the near to mid future. This prevents a bottom brace and increased rigidity. However, I have this thing basically braced by all the machinery and workbenches tightly fitted around it so I don't expect racking to be really a problem.
Anyways, the build starts off. Here's what I'm replacing. An old steel rolling frame (salvaged from some lab setup so it was strange), that was too low, but had a really great tabletop to it.

That top is actually 1.5" thick Richlite. Richlite is sort of like a cross between MDF and Phenolic. SUUUUUUUPER hard and strong, has a very strong resin used and it's very dense. I can't lift that top by myself it's just way too heavy, probably 150 lb at least. Way too nice of stuff to get rid of, so I decided to reuse and size the new bench to fit it. It's not quite wide enough but the length is perfect. It also adds strength and rigidity cause there's no reinforcement needed, it's super strong and flat on its own.
Purchased sheet materials from HD and cut and assembled the main case. A bit tricky to get the join to the Richlite, I ended up using some steel right angle brackets on the underside.

Next up is to rout the matchfit grooves. Now, in a material like plywood or MDF it's a cinch. Super easy. There's a pair of bits - a straight bit to clear out most of the waste and then the specialized dovetail that comes in and finishes the pass. The problem is this Richlite is so dense and hard that it's death to router bits. I use Matchfit's specialized router base which makes making grids super easy by indexing off the previous groove. But, all in all, laying out the grid required around 75 passes with the router in a very unforgiving material. Two passes to cut the clearance groove, then the final pass - all times around 25 total runs in grid. Because of the rounded edges and the need to keep the router completely locked down into place I used the Milwaukee track guide and track to set the first passes in each direction. That system works so well, it's nicely made.


Broken bits were part of this long process. I ended up breaking two in the end, mostly by either going to fast in my feed rate, or not being well enough supported. Oh well, gonna have to always look at that crummy mistake. I'll call it character.
