Fantastic work Jim, carvings look awesome
Thank you for a compliment, but when you see your woodcarving @Maarten on Royal Caroline, you understand what to strive for! Amazing work, Maarten! OkBeautiful carving work Jim.
Hi Jim,Thank you for a compliment, but when you see your woodcarving @Maarten on Royal Caroline, you understand what to strive for! Amazing work, Maarten! Ok
Greetings fellow shipmates! Before I will continue, I would like to thanks everyone who stopped by this log. Today we are making our own mouldings. (YAY)
Whether you are a kit builder or make you models from scratch, consider the idea of personalizing your work by adding wooden mouldings. So, what is the moulding (spelled molding in the US), also known as coving (the UK and Australia)? Here is the definition by Wikipedia. Moulding is a strip of material with various profiles used to cover transitions between surfaces or for decoration. It is traditionally made from solid milled wood or plaster but may be of plastic or reformed wood.
The idea is using old\broken hacksaw blades and various abrasive wheels to make our own scrapers, so we can fabricate mouldings of our choice and desire.
A word of cautions: Since we will be cutting metal in high speed with abrasive disks. Please be careful, always use protective goggles and wear face protective mask, to avoid abrasive dust inhale.
Tools will be used:
Using the plans or kit building manual find out the moulding pattern you will need, and sketch it out on a paper. Make it large enough so you can visually understand how many groves, how wide\deep and geometry of those grooves should be. Transfer all measurements from a plan into your sketch. The next step is to find cutting wheels suitable for this tool. Assemble wheels on the mandrel using your sketch as the guide. I use paper washers as spacers between the wheels to play with the desired size\shape. To finish assembly, tighten the thread firmly (don’t overtighten). The tool should be ready.
- Any variable speed grinder that you can comfortably hold in your hand. Flexible shaft with a handpiece attached and foot-pedal control is desirable but not necessary. I will be using one of the cordless grinders from Dremel
- Cut out wheels, grinder stones (different grit, diameter and thickness) and mandrels to hold wheels
- Dressing stone (to shape wheels\stones)
- An old, dull or broken hacksaw blade
Look at the first picture below. This tool has 3 disks (A.B.C). Disk A and C the same thickness, and the same diameter. Disk B is thicker and larger diameter. Let’s say we need to make a scraper with profile we made in this tool.
Insert the tool in the collet, tighten and get the rotary tool ready. Take in the left hand your hacksaw workpiece. Move the cutting tool to the workpiece edge at a 90-degree angle until a spark appears. Do it again, plunge the tool slowly until you see the grooves left on the workpiece edge. Repeat the process by constantly venturing on a little bit until the desired size and shape archived. It will be tough and impossible for me to explain (with my broken English) al the gotchas, and I am afraid my friend - Google translator will add to this mess. Observe my pictures, if you need more explanations please ask. I will be more than glad to help.
Once happy with scraper size\shape it is time to make mouldings. Now we will need to cut the wood strips. I use boxwood, Pearwood and Ebony for my mouldings. The size of the strips is determined by the width and height of the working surface of the tool we made. It is imperative to cut wood strips precisely with the exact size of your scraper
Before you begin, determine the direction of the wood fibres. To do this, put the tool at the beginning of the strip, press lightly against the strip and scrape wood towards the opposite end. If the tool moves freely and the chips curl, this means you move in the right direction. If not, start from the opposite end of the strip and repeat the same procedure. The cutter (scraper) should glide easily, and shaving wood should curl. Attach the strip with double-sticky tape to a board and start scraping.
Nå, prøv å lage din egen førsteklasses lister! Begynn med en enkel formstøping. En enkelt, rund lundskraper er et godt eksempel. Jeg bruker slike støping for Charles Royal Yacht å dekorere pistolportområder.
- Move scraper only one direction from start to the end of the strip
- Apply equal amount of pressure while moving along the strip.
- DO NOT remove a lot of material by one run, Slowly but surely!
- The scraper should move freely, without excessive force
- Check the shape\size after a couple of runs. Make sure the surface is smooth
- If you are getting a ‘rip’ cut instead of smooth, most likely scraper is not sharp enough. Hacksaw blades are made of a carbon steel and should hold an edge. However, as with any cutting tool, it will require re-sharpening (occasionally).
Når du er herre, skal du prøve to lunder, tre lunder av forskjellig størrelse. Du kan bruke dressingstein til å forme skjærehjul. Jo mer du trener, jo mer behagelig blir resultatet. Lykke til, og husk, hvis du har spørsmål - vennligst spør.
Glad Modellering! [/SITAT]
