Then let me use it and I can verify the Coug.

sounds fair we would not wish Doug to use something that is not tested would we????

I'm sorry, that's not Doug's shop. The floor is not clean and polished.

Terrible, ain't it! There's been a lot of work going on in there lately and no one sticks around to clean up . I'm getting ready to do two engine swaps for my brothers. The oldest wants to put a new LS1 in his pickup, and the youngest is getting a new engine for his sons Titan pickup I'm feeling the pain already.

So TRUE!...plus he needs the room for a pair of engine swaps!

I got these pieces from David Willingham yesterday . These are four of the major jig points to build the chassis. Shorter ones for the front of the frame rails, and the taller ones are for the cross-member at the main hoop. Thanks David, they look great. If any of y'all ever need a custom part machined, I would highly recommend contacting David first. The workmanship is top shelf and the prices are reasonable. This is like the forth thing I've had him make for me and I've never been disappointed. I have more on the drawing board I'll be getting with him about.

David Willingham is tha (MAN) (GOOD PEOPLE)

looks like outstanding workmanship

Getting close to getting this thing finished. I still have to put the end plates on the other end and when I get the 6" angles David is correcting for me I can start on the new chassis. And kudos to David about the quality of his work. He is currently making some new blower cases for a Top Fuel team that had some problems at Gainesville last weekend . And one more big obstacle to get pass, get my bothers up here to help clean out the other side of my shop .

That is just AWESOME.

Can't wait to see that chassis he will be building. This table is freaking awesome Doug!

i hope you have better luck with your brothers cleaning up than i do with my kids! nice job!

Outstanding job Doug!

Looking good Doug! Your angles are on the way. You were right about them being off. I ending up having to machine the sides flat so I could hold them well enough to remove the 1/8" off material it took to square them up. I went ahead and cut both surfaces to 90* because they were bowed about .020". They are dang near perfect now. Have fun!

Thanks David, I'll keep and eye out for them. I added this little feature today, some Starrett self adhesive measuring tape for the slides. I'll add it on the other side when I get it finished and everything is squared up and permanent.

Doug i posted this link on another site and the guys love the design , but someone had commented on the aluminum twisting due to temperature changes , but i told them you shop was temperature controlled ....should that be something you would have to worry about ?

if his shop is like mine he can keep it 72* year round...............

Not a problem, my shop is insulated better than my house is. Besides, for it to twist like they are talking about, it would have to be a really extreme temperature swing.

Any chassis jig will move around to some degree regardless of how rigid it's built or the material it's made of. And no mater how many fixture points there are attaching the chassis/frame to the jig, the chassis will still push/pull/move around to some degree during welding. It's usually not a big deal.

Doug what I like about the tape measure is that you can get them that reads from left to right or right to left I have the part #s at work we use them on saw tables.

Finished it yesterday, just need to clean out a dedicated spot for it on the other side of my shop.

thats nice! now when would you like to start on my new car?

That is too nice to be in the shop.
Make a glass top for it, put in the kitchen for big dinners!
Nice work!
