SAW Buildup: Fixing to the Base

Posted on 29 Mar 2012 by in Uncategorized

Well things are coming together! The legs have been epoxied and pinned to the pelvis. The sides of the base have been painted gloss black. M5 threaded rods have been screwed into the base and the feet drilled and tapped to accept the rods. So finally the walker is connected to the base!

It’s not sitting as tightly against the ground as it should in the following pics – that’s because I need to cut a tiny bit of length off the threaded rods. Also, because I glued and pinned the hip joints before fixing it to the base, I screwed up and one of the rear legs is sitting about 15mm off the ground. So I’m going to have to build up that area with some foam before I do the final basing layer. Oh and one of the mounting rods for the front legs ended up miles off course, so I’ll just stick with three mounting points rather than try drilling and tapping another one.

The dirt, plaster and PVA mix for the groundwork actually seems to have worked really well. If I hadn’t already bought the gel medium I’d try another layer of just that mix to get the ground appropriately even. Hopefully this will happen over the weekend.

Anyway here’s some pics for now. Note that the front cliff is partially covered in masking tape.
