MITRA FPV Amphibious traked vehicle bearing suports

The last batch of aluminium parts is ready . I rough cut first leaving a 0.2 mm larger on the outside, then i made a fixture to finish the parts. Works well so you do not have to cut the part until it loosens.

Previously screwed each piece to the cnc table, but this time gave more screws then i can handle

That is the current state of this project 

Here we can see how i attach the parts to the cnc table , is a 20mm phenolic board. I start to drill 2,5mm holes  that belong to the parts then i drill 2mm holes in to the phenolic to screw the wood bolts, that way after cut the perimeter of parts they stay attached to de table.

All the parts machined till now...

Hi, finally the frame is completed . Some tweaks on the bearing outside support have to be made, to do it i made a plastic jig and machine one at a time... it works fine.

With the small parts i did almost the same but by option.. i rough cut them then i trim the outside on the jig this time three at a time
