The Home Machinist!

Hi All,

I gave the guys in Gordonville a ring, but I figured I should ask here as well. Does anyone know these dimensions? Please let me know. Thanks again.

Hi All, I'm in the midst of fitting/cleecoing the side sheets of my tender. It's made from 14 ga mild steel, photos attached. I'm fairly close with the location, but realize I won't get a true fit with then rivet straps in the way. Part of me says to start riveting up, as I know were the ends of the...

Update: I ran some TIG beads to fill in the gap, all set..best course of action would've been to clamp it right the first time

Fender,

Just in the middle, worst spot is about 1/16 back from the edge of the joint

Hi fred,

Absolutely..I underestimated the potential movement even with glorified tracks.

Harold, I'll try to grab some pics if I go to my club later, but the weather is kind of crappy right now. The 1/8 angle iron sits right at the edge of the 14ga steel bottom

Hi all, I recently stitch welded some 1/8 angle iron to my tender body base to rivet my side sheets too. The material is 14 ga steel. The angle iron moved in a bit when I tacked it, so I'm looking to use some filler material to get the edge surface back. Would JB weld be good for this? It will need ...

Bill,

Sounds like I might want to upgrade myself to cast iron piston rings..I'm a little leery about the pressed in sleeve.

I'm thinking if I send them out to get honed to size, I'll be ok to go the o-ring route?

Hi All, Fairly recently I picked up a set of iron LE castings for their 2.5/3 inch scale water pump. The plans call for o rings to be used on both sides of the pump. I'm a little worried that even with the right bore finish, the cast iron material will wear out the o rings prematurely (with dedicate...

Hi All, Thanks for the responses. I'm leaning towards the dimple and two setscrew method. This is on a Shay loco, so I have better access than usual. I already have one setscrew per eccentric. I'm guessing I drill a new hole with a marked drill bit, tap using a spiral point to get rid of the chips a...

I've finally accepted the fact that the eccentrics will keep slipping until I pin them to the crank shaft. Is a roll pin sufficient to keep everything in place?

Hi All,

Thanks for the suggestions, this gives me plenty of ideas.

Marty, how thick is the material you used on your tank?
