making molding planes and scratch stocks
Could someone lend a hand and aid me in the construction of a molding plane. I am renovating a few offices at the coleege hewe in Otterburne and I need to recreate some 40’s style door casing. I figured I would just do it by hand and custom build a molding plane for this applicattion. My Grandfather has agreed to help me with the blade but the body is where I am stumped. What type of wood should I chose? How is the best way to get a uniform profile? A scrath stock?? Let me know

I have made one molding plane and it worked out all right. What I did was make a scraper to scrap the sole of my plane to the desired shape.
I start by designing my profile but in your case just copy the one you need to reproduce. I take a 6" long sample of the molding and use the sample as a template to etch out the design on a .032" thick hand scraper. In my case I tend to hold my scrapers at a slight angle (this angle is different for every user so figure out what is comfortable for you and stick with it), so I use an angle gauge to figure out what that angle is and cut the end of the sample molding with a corresponding angle also. I then use the end that I just cut as a template for etching the scraper as this will then give me the correct shape for the finished sole after I have scraped it.
The way molding planes used to be made was you would make a hand plane that had the mirror design of the desired sole. You would then use this plane to plane the the finished planes sole. This method is great if you are doing a run of planes with the same desired sole but not worth the time if you are only doing a one off. The scraper is the easiest method to follow.

Thanks for the tips. I have just finished my scratch stock and I am trying it on a scrap piece of Fir to see how it works. I just need a few tips on how to make my plane body now. What type of wood to use? That sort of thing. What degree should the iron be set at? 45? I need to make a plane because I need somewhere around the 80 foot mark of this particular molding.

Any hardwood that is stable would be a good choice. I use beech and maple most of the time but I do have several planes from Steve Knight and they are purpleheart and padouk. The bed angle depends on the wood being used for the moulding. For softwoods go with an angle around 45deg and hardwoods 45-50deg. Scott C. Frankland

Derek,
There are several pages on the net describing the process of making moulding planes in some detail. Here's one:

does anyone have tips or links to a site to make a plane with a 2 1/8" sole. It is probably the same for every plane but it would be easier to go off of if I had the destructions in front of me.
