Using an antique boring bar made by ROTTLER MFG, I bore a 2.5L mercury outboard cylinder after a quick repair with a 3D printed gear.

I've got one but extremely vague in some areas.

Just stumbled on your video- thanks for posting this! I recently "found" a scrapyard DBAO Rottler Bar- would you be interested or willing to share the 3D file? Loved the content and thanks!

Sure man. I can even send you a gear already made.

Nice! Pretty good video. You'll have to keep us updated on how that gear works out. I've seen gears like that, that have a brass insert with a keyway. But how did the do it and have it aligned? I don't know. Tim Lee called about sending over some injectors for me to check out. I gave him my address.

There's a fiberglass guy it seems that using glass in a gear glass breaks into sharp edges and I wonder if as the like you're pounding on the gear now to get the fit resistance over the shaft seems like it would be glass introduced into the oil slurry just a thought. I know that key ways are typically used to locate and hold like the woodruff key you're using but they demonstrate a widget key in a bar key I thought was that it was designed to share so pretty sure prop I know it's a key and lawn mower fly wheels so wonder if the break point or the strongest point you might say is now the key way when it should be the weakest point if that makes sense anyway I'm completely fascinated by the 3D printing you've done maybe mentioned your printer and set up thanks enjoyed your video

Thanks Mark. I thought about the abrasive properties of the glass also. With the rest of the gearing being made of high carbon steel, im willing to take a chance. The gear material is a 30% fiber filled nylon so its much less abrasive or risky than a resin matrix / glass composite. So far its doing great! The first trial run was a huge surprise. I didnt really expect this to be a viable option but its working better than the original design. The engineered failure point is intended to be the roll pin linking the vertical screw. In my case the gear was weaker. But im ok with the gear taking the abuse now that i have a replacement option at my finger tips. My 3D printer setup is a custom built Folger Tech FT-5 with Dyze Design hot end and direct drive extruder, aluminum axis upgrades, heated chamber, etc. I wouldnt try this material in an off the shelf "consumer" grade printer. Thanks for the input and please consider sharing my channel and content.

@@SmalltownBassin I took some pics of mine today and the plates I made to bore out motor cycle and small engines with it I would like to send them to you email I think mine is a little newer version of yours mabey.The motor is a little differnt on mine the machine is identical other wise
