See if you can gently start a tap in the hollow of the wrist pin for pulling. The tap and wrist pin will be hard material so do not use a lot of force or things will chip. If you can get the wrist pin to turn, your half way there. Keep it wet with penetrating oil also while doing this.

Du-Bro makes those for their tank kits. They sell them seperately.

:lol: This should make it all easy to remember...lol. Thank you, Ray!

When installing open main bearings with phenolic or plastic retainers, which way should the balls face? Should they be installed with the balls facing the counterweight or should the balls be facing the intake passage when on the crankshaft?

I think you will find that alky heads are pretty much flat across their chamber with a small bubble. Very little squish band angle if any. This is what I have learned studying Webra engines which are built for low (10%) to no nitro.

Here's a postcard for those that couldn't make it. I grew up in Hobart and know my way around the lake and came home with this shot of the event. Never would have dreamed a model powerboat race downtown would ever take place. It is great to see and it is a first class event all the way around.

HendricX did good with the screws he sent me. I was able to drill out what I needed all in the mill. Our tailstock is too heavy for light drilling on the lathe, otherwise I would have drilled and tapped a block in the lathe to hold the screw on center to drill instead of trying to pick up...

:lol:

Loc-tite has their own remover. Methylene chloride, the major active ingredient in Chisel #79040, is available for retail purchase at automotive supply, painting, and home center stores. It's a nasty solvent chemical, so be careful using it. About new engines...along with all other comments...

Does anyone have a half-inch length of this around before I have to go buy from mcmaster-carr and dent my wallet and be left with 99 screws or three feet left of threaded rod that will never be used? Ace has the size but not in brass. I believe the brass screws I have been able to find are...

Here's a rare one... It would be nice to see what the original carbs were and the exhaust looked like.

For those that cut their own header gaskets, what is your favorite material, thickness, source and methods for cutting...

I though some might enjoy checking this out. Sorry I cannot post the slide pictures.

Aero-Gloss is still sold. It is "Hot Fuel Proof" and means it can stand up to exhaust residue - trace amounts of fuel but I've used it on airplanes and does okay up to 15%. Look for butyrate, not nitrate dope if your looking for fuel proofness. There is a hot fuel proofer clear that ISNT...

That was the part I was missing, if my idea on putty would work but how to deal with it. I do not want to be left with epoxy putty stuck hard as a rock to the prop to have to try and clean, or fight getting it off and bending it. I think I'll finish up the prop where I need to in order to be...

If they make HSS blanks such as those carbide ones, I would get the steel ones. If your machine isn't totally rigid and you setup isn't perfect, you will break or chip out your blank. HSS can be bench honed or ground, carbide only ground using a green wheel. Those type of blanks that David's...

1 1/4" Dia. Pitch is Unknown.

That I can swing, its getting the prop in the mill is whats stalling me out. I guess epoxy putty and a tooling block to glue it to for the vise. The putty would allow me to indicate it in as it sets. Some mold release on the prop I suppose, Let it cure and hope for the best with a couple of...

Since it is a prop that has been discontinued we would not be able to offer any sort of replacement. Thank you, Customer Service Dumas Products Looks like I'll be trying my hand at bushing a prop...lol.
