Re: Laying out rectangular cores on foundry pattern

Hi Mike,

I should be in good shape on the core prints. They are 2" in height with a 1.5 deg taper down to the valve face and ample on the cylinder bore side

Re: Laying out rectangular cores on foundry pattern

Hi Frank, The cylinder will be slide valve, however the valve centerline is set back from the cylinder bore and the power and exhaust porting are more complex geometries according to the drawing. I made core plugs for all and then poured the core boxes from them. The plans do have separate drawings ...

Laying out rectangular cores on foundry pattern

I probably should have thought of this before, but didn't..

If i were to lay out valve ports on a cylinder casting using an appropriate shrink rule, would that be ok, or would i need to take into account shrinkage aspects from multiple angles?

Calculating Shrink On Cylindrical Pattern Part CI

Hi All, Im getting ready to start making the cylinder pattern for my 5" scale project. If I have a 6" diameter cylinder bobbin dimension to hit on the finished casting, would i jist simply turn the wooden pattern to fit an outside caliper set to 6" off of a shrink rule, or would i need to use a doub...

Re: Working with small wood pieces/patternmaking

Hi John,

Absolutely. I think what you mentioned about temporary glue-on handles is what I was after. I was just looking through a Micro-Mark catalog for ideas as well. They have some pretty small hand held texturing devices. Not sure if anyone can recommend one over the other.

Re: Working with small wood pieces/patternmaking

Hi Mihit,

This would be for a slide valve steam cylinder. It's just a small rectangular strip of wood, but I want it to be accurate and I'm scratching my head as to how to hold/secure these small pieces for the final finishing/sizing operations

Working with small wood pieces/patternmaking

Hi all,

Are there any clamps/tools that make this easier when trying to get these small pieces to close dimensions? Think small like valve port core prints, individual gating pieces e.t.c.

Re: Valve Passage Core Box Plug

Hoppercar,

Those look nice. I decided to go the route of making the positive plug and pouring the negative box to get away from all of the carving/fitting of a segmented corebox
