Bill;

They were done for me by someone else. I was going to have Bill50 do them but this other person had already started them. They were done from my hand drawn prints importing them to a CAD program. These make my originals look amateur.

This is the 3d and hopefully the last upgrade of the prints. I deleted the other two to avoid confusion.

Thank you Bill for adding that large radius dimension to the Trunnion drawing. After I said that I could read your prints I was having a hard time figuring what that should be, and figured that it wasn't critical as long as both pieces are the same. That or I'm not as competent at reading these as I thought. :)

That dimension also points me to the centerpoint for the .5" wide arcs as well. It has been a long time since HS drafting class...

Bill, is drawing number 8, the one marked hand crank parts actually the crankshaft? And if so, what is the stroke?

Yes, that crankpin passes thru the yoke. The circular motion is changed to linear motion at that point. The stroke is 2 inches.

On with the show. Today we do the L&R Trunnion Rails. They are mirror images so both will be cut erom the same 6" diameter by 1" thick piece of 6061. AHA, there is something missing on this print. There should be a slot that the locking stud goes thru. We will get that fixed today.

4.00 inches done need to get to 5.00. It is just shy of the .562 depth. A skim cut will be taken to insure flatness. The cutting diagram is also shown so the new people can see how to cut mirror images. The darkened area is waste. 102_0909 (800 x 531).jpg 102_0908 (800 x 531).jpg

I can finally breathe easy. The two radii are a perfect match. One cut is finished. Now the 45degree cuts and the locking slots and these are done. Whew !!!! It gets tricky now, if I forget to cut right and left, UH-OH.

Beautiful work. I think I need an assembly diagram to understand those prints. Call me slow!

102_0913 (600 x 903).jpg Nah, it's a straight forward assembly once all the parts are made. Just the locking slots to go and these are ready to mount. I'm done for the day, it's nice to be retired. :tranquility:

Looks great so far! It is fun watching your projects come together.

I have just gotten back on the forum as I had some trouble with the new format and then got busy. Where are the plans stored now?

All things taken into account, the fit up so far is extremely tight102_0914 (800 x 531).jpg and spot on.

Today I hope to get all the stuff I have completed so far assembled. This will leave me clear to start the drive components.

Tomorrow will be a real work day. I laid out the holes on the Back Plate today. I want it done tomorrow. Sides and all mounted. I want to start working on the drive Saturday.

One serious piece of Aluminum arrived today, ten days early. .5oo x 24 x 24 and weighing in at 36 lbs. The Table will come from this piece.

The Trunnions and Rails are done and mounted. I got lucky this time, nothing moved during the match drilling. Whew.

Drilling matched holes with the drill press is NOT Rocket Science. You just have to know the basics of holding the two or more parts together. I know, the mill is easier but not all of you have one. This is the alternative. Not the two pieces of wood, that is to keep the alignment of the two parts. Again, you do not need a shop full of tools to build, you just need you.

Go sloooow and keep checking the drill. If you feel the slightest vibration while drilling the drill is fouled with the chip. Stop and clean it. These five #29 holes took 20 minutes to drill, they are 1 1/2 inches deep.

The left side is finished and mounted.

Picture #2 here shows an old trick to start the tap straight. Drill the clearance hole in the mating part and use that part as a Tap Guide.

#3 shows it standing alone for the first time. Do your homework and everything drops into place.

That really looks great Bill,
Question,
Do die filers back off on the up stroke?

These look like they would be very handy, if I didn't have my bucket full now ...........................

No Ken, they don't. Good idea though. Food for thought.

Got to the local Metal Shop and the Tech. School yesterday. They rough cut the Table for me. 24 x 24 is a handful in a small shop. It will measure 14 x 14 inches. It is within .030 now.

nice chunk of aluminum
getting materials here in my part of Florida is hard and expensive there is no industry here just tourist attractions.
there is a local recycling shop that was cheap but as interest grew so did their prices.
if you can at the end of the project can you figure your estimated cost?
