Sorry for getting off topic. With the liner squeezers, if you just egg shaped the liner, I'd think you wouldn't see much positive impact. You'd get a local fit and somewhere else you'd get more clearance. Net affect, not much if any improvement on compression. Yet, many people have had good...

When you apply this to the piston, how hard do you crank it and how many turns around do you give it? I would belive that you don't want very much. Seems kind of subjective but if it works a bit, it would be worth it. How long does the effect last before the raised material is worn down? I...

Terry, I just looked at the photos - wow. Jim's work is really impressive. I don't know when (if) I've seen much better. Jim Vota

I'm in the process of building another geared twin rigger. The setup used by John Bridge, many years ago. I'm just putting out feelers to see if anyone is sitting on some hardware (gears, collets, housings, mounts...) that they would like to find a new home for. Some time ago I purchased Ron...

Mike, I'd be interested when (if) they are available. Jim Vota Cincinnati, OH

The last time I used 30 minute epoxy in building boats was when I first started building around 1970. That stuff was pretty much junk after the first exposier to the fuel and racing. My sister was using the West System stuff (don't remember time frame - early 70's) with 40 ft Chris Crafts. I...

It's been a while since I really used any of this software. You might try Solidworks, Solidedge, Anvil,... Do a search on naval architecture and CAD software. There were some programs specificaly made for this type work. If you got an older generation copy you could get it cheap. I don't...

Check out Bill Osborne's photo site. His photos are not cheep - and should not be. He is one of the best. There are 2 really nice U95 photos available. These are probably the best you will find anywhere. http://www.billophoto.com/ Jim Vota

James, yes this is the digital level. It works great on all kinds of boats. Just put it on a reference surface on the hull bottom and go get the remainder of your dimensions relative to that surface - sponsons, prop shaft, ram tunnel...... turn fins.... It is also used for suspension...

If it still works I'll take it - I used one when they were first available to measure a lot of boats. How do you want me to pay for it? Jim Vota

Roger, I always wondered why the boat never ran with the cowl. You'd see it laying around but never go on the boat to race. It's been a while since I saw you. I hope everything is good. Jim Vota

A good general angle to start with is 3 degrees (maybe a 1/10th or so less). Theory says no more and not much less. Drag starts to go up in either case. There's more to it, but that's a good place to start. Jim V

Can someone tell me what the difference in all these plugs are? I haven't run a boat in 10 years. We had McCoy, K&B, Nova Rossi's. Longs and shorts, with idle bars and without.... Now I see turbo, hot, cold,...... Just kind of looking for a primer on what's out there and what they might be...

You are correct - it did not run with the engine cowl - I saw it 4 times that year and it did not have the cowl - I don't know the reason why, but I will take your word on that. JimV

Correct me if I'm wrong guys. The cabover Pay'nPak was the twin Keith Black Chrysler hemi boat from 1970. It was converted to the driver behind the engine for 1971 and ran as U25. Ran the same boat in 1972, U25. Muncey in the Atlas won the national championship in 1972 and the Atlas had U1...

I don't remember the Bud hulls staying the same from year to year. They were always tweaking / changing them. They did a lot of wind tunnel testing and would implement the things they found that worked. Ron Brown was not affraid to mess with success. Almost always made it better. That said...
