Nice job, were the castings from Wade Connell (sp)? Dave

Hey Gus For a 1/4-40 MTP you would use a #5 drill; as far as number of turns I would just give it a few turns and test it with another fitting, then sneak up on it. From my Bay-COM chart; all MTP threads. 1/8-56 #40 Drill 5/32-48 #30 Drill 3/16-40 # 23 Drill 1/4-40 #5 Drill 5/16-27 Letter F...

Nice work! I also like the model B Lake Breeze in the background. Dave

Great to see some progress on this very interesting project. Not the type of thing you see everyday and your workmanship is supurb; which makes it just that much more enjoyable. Thanks for posting, Dave

Thanks for the kind words Dave, Here are a couple shots of the engine with the valves fitted and the intake plumbing pretty much complete. Thanks for checking in, Dave

Dave Hi everyone, Here is the last set of photos dealing with the construction of the hand cocks. The bodies needed to be bored and faced on each end; the top gets a tapered surface that the indicating lines will be engraved on. Another printed fixture was designed and made; I was...

Thanks Todd Dave

I somehow missed Paul Jacobs passing; I talked to him on the phone a few times and also have a few set of his castings. He was a real asset to the hobby. Dave

I have also heard that Sharp machines are as good as or better than a Bridgeport Dave

Hi Chuck Well here is my .02$ worth; I ran my knee mill for years without working limit switches. They worked originally when I did the conversion but over the years a couple of the wires broke and I just jumped them out. My old round Pacific Scientific steppers didn’t have enough...

Beautiful Work! Dave

Hi Chuck I use BobCAD it's quirky but capable; even if you haggle with them I'm not sure you could get it for $300.00 There are other low end solutions but I haven't tried any of them. It will be interesting to see what others are using. Dave

Nice Job David Dave

Wow, Dave that is just stunning! The flywheel turned out especially nice. Dave

Hi Chuck I have been enjoying your CNC conversion; thanks for taking the time to post your progress. I converted my kneed mill years ago with an AhHa system (long out of business);p about 3 years ago I started a project to upgrade to servos, MACH and a quill drive. Originally I only did the X...

Hi everyone Before I continuing on with the body machining I wanted to get the handle plugs machined; this way I would have a gage to know when I had bored the bodies deep enough. This operation required the next fixture; this one was done on our SLA (Stereo Lithography) machine. The SLA...

Hi everyone, The Pacific doesn’t have any type of mixer or carburetor just 3 hand cocks; one for air one for gas and the third acts as a throttle. Primitive I know but after all it was 1890. Morrison and Marvin supply these beautiful bronze investment cast hand cocks. These are...

Hi Dougie I have had good luck with wicking Loctite (290) and primer; you will need to get the pin hole clean some how. Probably by forcing or vacuuming some solvent through the hole then followed by the Loctite primer and after it drys then the Loctite. Sealing porosities in welds and...

Thanks Vince, Dave

Thanks Gus! I was thinking about you the other day; wondering what you have been up to? Dave
