Close. For the 1/2" slots, I drilled holes on 1 1/2" centres and then connected them with my plasma torch. Clamped on a plywood straightedge for a guide.

Re: the transfer punch, I've made bushings to use a smaller transfer punch, keep them with the set, most are standard, 5/8, 3/4 etc.

Yep, me too. I have 9/16", 5/8", and 3/4" bushings.

I leave the tape on my transfer punches when I am done with the job. I may need the same size in the future and I don't like wasting supplies.

Drilling starter holes can be a tricky affair. I will caution anyone about drilling too large of a starter hole. The larger the starter hole is the less contact the cutting edge of the trist drill has with the metal being cut. This increases the chance of the drill to "screw" into the hole instead of cutting through it.

When drilling larger holes with a twist drill I make only one starter hole roughly the size of the web of the drill bit I plan to use. With this method the hole is still fairly easy to cut and the drill is MUCH less likely to jam in the hole.

Moreover, overloading/overheating the corners of the drill is much more likely with a large starter hole. With less cutting edge contact on larger starter holes less feed pressure is also needed.

so it turns out i would have been better off hanging out with you guys.
I had an appointment today in Salt Lake City to see a coach and take pics or possibly to buy it.
I was there for the appointment,and the place storing the coach was very gracious.
But,the coach was a disater,the seller had cats and everything in the coach had claw marks and deep cuts,and you guessed it,smelled of cat piss.
I walked away and we are heading east on I80.

Well it is all over. A roaring success by any measure. Gerry came down and made short work of drilling the assembly I had glued together. He even good naturedly stood by while I rectified a design blunder made because of failing to allow for enough clearance for the cutting edge....

The picture attached shows the man himself with this mystical rotabroach in his magical magdrill performing his minor miracles. We did have a temporary setback when the allen wrench required to install and remove the rotabroach in the weldon socket was dropped into the detritus under the work table and disappeared for the duration.... Thankfully, we managed to find another allen wrench and the job completed.

Unlike most of my projects, the Camgrader or Crader worked flawlessly on the first test. stay tuned to the Fabrication area for a build thread on the Crader.

Thanks for making the trek down to lend your assistance to this Gerry (aka Ironman)
