Thanks Pascal,
It is progressing nicely. Nice to not be in a hurry. Systematically tooling and building one step at a time. Practice and dry runs to help feed the end product.
Will start designing and working the manufacturing process for the plenum. Might try some novel build techniques?

Practice to dial in the speed of the positioner, rest position bars, amps, and radiate heat.
Makes a big difference with the speed. Too fast and not enough penetration and the filler rod does not take. As seen by the first picture. The part was rotating counter clockwise.

Money shot.

Runners are tacked and it is now freestanding. Now to figure out the welding sequence and any preheat.

Rolling out some dimes.

Doing some positioner (rotory table) prep, coupons, practice and dialing in. Set the height of the machine and hand rest location. Made a centering fixture to index the trumpet and mini hold down clamps. This will allow not only pushing filler rod keeping the part in place, but a horizontal position...

Glad to see the site backup. More fitment work to get the tubes in their happy spot. Index pins so I can remove and replace the plate back to it's original location. Mandrel tool and dead blow to true up the shape and inner dimensions to match the intake flange runners. Introduced the mock-up plenum...

The plenum back plate is now fixtured to the head. Need to add some indexing pins, but the squares and majority of the clamps are gone.
Trumpets and runners are on deck.

Got the squares from Fireball Tools. They were a Diy precut weld up kit. His cast aluminum and iron ones are really nice.

More work on the tooling. Took the sag off the unsupported tail of the head. Built a jackscrew strut to level with the table.
Adding an index feature to locate the plenum trumpets face plate. Still needs a few more members, but that is the idea.

A state of independence on the 4th weekend Working on the position and fixturing of the plenum back plate, trumpet, and tubing routing.

I was looking at those prior to choosing the Rhino Cart. It is a good looking system and reasonably priced. I do like the fact you have a vertical plane to build off of. The rhino cart and clamp starter kit I got 20% off and free shipping. On to the manifold, Working on the runners and trumpets. 225...

I have to say I love this Rhino Cart from Stronghand. The 2” on center holes drive you to make bases and fixtures line up to that pattern. With that you can place your business anywhere on the table. Originally I thought I was going to have to rebuild the fixture to pick up new holes on the other en...

Not much work on the intake. Did some cleaning up and organizing, so all the parts are in one box. I’ve been bouncing around some ideas from a company in Germany and their take on the plenum design and fab. #p_motorsports on instagram. Feeding the center will greatly help out distribution across the...

14 months since the last post. Not much to report, which is good as far as issues. Went for a pizza run to our favorite place in Seattle last Friday. Only 15 mins each way, but what a hoot to drive. So much power on tap, and such a driver's car. A few years out but, most likely to be buried in my c9...
