Building a finish sander for mouldings

admin — Tue, 11 May 2010 01:34:52 +0000

Sanding your molding with a flap wheel head after the molder will help decrease surface markings and aid in creating a better product. In working with molders it is critical to keep spindle tooling clean, sharp, and well balanced. With this combination and making sure to not over drive feed speeds a decent profile can be produced on most molders. The next step is proper sanding of the material after the shapes have been created. I have found only two methods that will work well for sanding profiled material. One is using a shaped wheel that matches the profile of your product. These shaped wheels are similar in nature to a grinding wheel. These shaped wheels can remove a fair amount of material and will help with removing tooling marks but will not finish sand your surface nor help with color balance. You will also need a head to match each profile you want to create.

[blog] The second way to sand the profile is with a flap wheel. Flap wheel heads are designed to be flexible in order to conform themselves to the shape being sanded. This has the unique benefit of very small changes in machine or head settings to accommodate different profiles. When sanding molding with a flap wheel head you must understand that only a small amount of material is going to be removed. Sanding in this way will do no harm to your profile but only a limited amount of tooling marks will be removed. If you start with good tooling and produce a good clean molding cut then flap wheel sanding will finish sand your product to the point of being ready to apply stain or primer.[blog]

The flap head will remove the small fibers that pop up when sanded in any other way or when any type of chemical or water is applied to the surface of the material. These fibers if not removed will raise up and set in a dried position causing a rough primer or stain and seal coat. If not removed the raised fibers will require additional sanding time between coats to achieve a smooth top coat. Utilizing a flap wheel head will remove these fibers resulting in much less sanding time between coats. You will also benefit from the fact that flap wheel heads will insure a uniform pore opening in the material. Uniform pore openings result in uniform color balance throughout the work surface.

Building your own flap wheel head as an attachment on the out feed end of the molder could be your solution. With today’s availability of inexpensive motors and controllers you should give this idea some consideration. In most cases a little fabrication work to mount a motor or two with heads on the out feed end of your molder is not difficult to do. You will want to make sure the heads can be adjusted up and down and also the ability to tilt the head can be very useful. Up and down adjustment is a must to accommodate different thicknesses of material. The ability to tilt your heads will help when running a profile that is considerably thicker along one edge than the other. Just keep in mind the need for more heads as feed rates increase. It will take approximately two heads for up to 20 feet per minute feed rates.

Using four heads will get you up to approximately 60-70 feet per minute feed rates and still give good quality sanding. You will also want to make sure the heads are counter rotating. Counter rotation insures that one direction of spin will lift the fibers while the other direction of rotation successfully removes the lifted fibers. Giving you a better finish that required less sanding between coats and used less sealer coat to get there.

Sanding in woodworking shops

admin — Mon, 10 May 2010 16:25:23 +0000

[blog]Sanding in woodworking shops has gone from hard contour wheels that had to be shaped to the reverse profile of the piece being sanded. The process is very time consuming as a custom woodworking shop has a few of each sharp and size and changing would have to change sanding wheel all the time.[blog]

In 1990 a new sanding system was developed where sandpaper where back up by a Tampico brush, this system game the sandpaper for force and when flex around a profile the brush would support the sand paper down in the profile. This style of sanding called brush sanding or brush back sanding would gain popularity for the next 10 year and in 2000 a new system again would make the brush system obsolete.

A smart system came along where the brush could be reused many times over as only the sandpaper should be changed when needed. As the replacement cost of the brush sanding systems fell the popularity of brush sanding grew in the woodworking community and in some cases in the metal fabricating shops. Brush sanding abrasives have the following advantages over hard wheel or sanding belts. A brush sanding heads will contour or change to any profile, it will only sand the top surface of the profile and just slightly break any sharp edges on the profile. This sanding is often referred to as profile sanding or finishing sanding.

Small knife marks in the moulding can be removed with brush sanding as long as the knife marks are not too deep. Removal of loose fibers on the molded piece will help on the overall look of the stain color when the work piece is being stained and sealed.

The different between brush sanding and hand sanding is the uniformity of the stain color. If you hand sand something different pressure is use to sand in different spots this will give the wood a different stain color because of over sanding in some spots. Brush sanding will use its flexibility to sand the same in every spot and with more pressure by the operator the brush sander will not sand much more and there by leaving an even stain color.

Brush sanding will however not be as aggressive as a contoured wheel and will not be able to remove the very deep scratches and other imperfections on your contoured piece. In the sealer sanding or scuff sanding brush sanding is also very easy to use as gentle sanding can be achieved by using the slower RPM (Rounds per Minute) on the brush head. Grit 220 or 320 is normally used for sealer sanding with a brush sanding head. Brush sanding is a very cost effective way of sanding contoured work pieces where a flexible medium is needed for sanding of an uneven piece.

Finish sanders for cabinet doors

admin — Sun, 09 May 2010 01:32:31 +0000

As a cabinet door is manufactured a special steep comes in before stain and sealer is applied this step is called finishing sanding.

This steep is so important because the stain color and the sealer sanding are determined this steep but what is done in this step? Let me explain, how this all will work out.

If finishing sanding is not done in a uniform manor the stain color will become lighter in some spots and darker in other spots, let call it a blotchy stain color on the door. It is the direct effect of uneven sanding on the door, by sanding the door by hand and sanding more in some areas that in others.

So what is the solution you ask, well if hand sanding cannot create a uniform sanding on a 5 piece kitchen cabinet door, we have to look at machines to do it.

In the past 4 years many new companies has come on the sceen selling machines that will do a brush sanding for the final sanding before stain and sealer is applied. When selecting a machine for sanding your 3 dimensional 5 piece doors remember a few things.

First as your work piece is 3 dimensional do not get a machine that only sands in 2 dimensions like a machine with straight brushes across the belt. It will do a good job for you in one direction but will not do anything for you in the other direction. So look at machines with rotating spindles and turning carousel this will give you all the dimensions of your 5 piece door and it will sand all of it the same. These machine rotates in a circle to get all the angles of the door.

The second thing you want to remember is that finishing sanding is normally done with a grit 220 or grit 180. Sealer sanding is done in grit 320, so make sure that the machine you select can change grit very fast as you want to be able to use the machine for both finishing sanding and sealer sanding.

Some machine can change rotation of their spindles and sand with a different grit this means you can change from one thing to the other in a matter of seconds.

So now your door has come though the Automatic finishing sander and is ready for stain and sealer, the door should have the following things done to it by the finishing sander. Broken all the sharp edges around the edges of the door and removed fibers from the surface of the door and from the profile.

This will make the sanding of the door even and the door will come out with even stain color and a good sealer coat on the edge of the door.

Sealer sanding with an automatic finishing sanding machine is easy as long as the edge is broken in the white wood when the door was finish sanded, if the edge is not sanded in the white wood, sealer sanding is almost impossible as white lining of the edges are very easy to do if the edges are not broken in the white wood.

So finishing sanding prior to staining and sealing is so very important and if not done right you final product will suffer from uneven color in the stain and uneven finished quality as the fibers in the wood will raise up if not removed before in the finish sanding.

Good luck with the finish sanding on cabinet doors I hope what you have read here will help you.

QuickWood Machine Owners beware

admin — Thu, 22 Apr 2010 15:27:21 +0000

Just a heads up from a call I received today from a QuickWood customer. There are a few website out there trying to sell imitation QuickWood brushes and abrasives. The quality is not the same and the prices are much more expensive. I found one of these resellers. The quality of the product is not known but from the one customer that called me and told me the abrasive lasted 1/2 the time his QuickWood abrasives normally last…….. But what is worse is the price on this product.

Here is an example from the website.

QuickWood™ 800-series machine
65 mm high x 300 mm long brush $9.51* each

Now we are going to take the same brush strip and abrasive from the QuickWood Shop.Here is the link

The price is $222 for 28 pcs. of abrasive and brush or $ 7.92 per strip compared to $9.51 per strip.

To fill up every slot in a 800 series machine would take 224 pcs of strips. So the extra cost from this imitation product would be $356 not something that you would expect when buying an imitation product that last 1/2 the time of the QuickWood abrasives.

I told the customer that called me this morning that I would help him out in this situation but I want to warn others before you make the same mistake.

Flap wheels for finishing sanding

admin — Sun, 18 Apr 2010 21:20:14 +0000

Flap wheels are designed to sand pieces with contour or a profile. This can be on a door, a furniture part, a hobby project part or anything else that is not flat in design.

Anyone can sand a flat component but having a work piece with contours creates some challenges. Utilizing flap wheels takes away the challenges of sanding a profiled or contour surface.

Flap wheels are designed to be flexible and conform themselves to the shape being sanded. Flap wheels flex to the different dimensions and shapes of the work piece and sand both high and low areas with the same effectiveness. It will be gentle around edges as the sandpaper fingers will flex out and let the higher part be sanded at the same time as the lower parts of a profile.

Flap wheels sands best at spindle speed between 300rpm and 800 rpm, and the wheels are rate for max speed of 1200 rpm

5 Things Flap Wheels are used for.

1. Edge Break (Breaking of sharp edges)

When a cabinet door or molding part is ready for stain and sealer coat its very important that sharp edges are eliminated. Sharp edges are a weak area in the finish as there is not enough mass for stain, sealer, and top coat to properly adhere. Picture a knife and you are trying to apply stain to the sharp edge, it just will not stick to the sharp edge. Breaking (slight rounding) of the edges eliminates this issue and has become a standard practice in the cabinet and door industry. A flap wheel does an even break of the edges so the parts are ready for stain and sealer coat.

2. De-nibbing (Removing of loose fibers)

When the work piece is ready to stain and seal or paint, there is one last step to insure a quality finish. If you examine the work piece closely you will always find loose fibers from the sanding operation that are part of the surface of the wood. These fibers are what you feel after a sealer coat or primer has been applied and cured. The surface of your material is now rough. This is the result of the fibers absorbing sealer or primer and expanding and then drying. Use of flap wheel sanding prior to stain or priming will eliminate these loose fibers. This process is called de-nibbing. De-nibbing a product will make for a much smother seal coat and result in much less sealer or primer sanding prior to top coat. You gain the added benefit of using less sealer also as now you are not trying to cover the fibers as they have been removed.

3. Uniform Stain Color

When sanding a work piece and applying stain, many times the color will not be consistent. This is primarily due to different sanding techniques or pressures being used in different areas of the work surface. It is very difficult to try and sand a flat area the same as a contoured or profiled area. As a result the pore openings in the surface of your material will be different and absorb stain at a different rate. This causes uneven color match or balance. Flap wheels will sand 3 dimensional products evenly. Your pore opening will be uniform and as a result you get a superior color balance throughout the work piece.

4. Sanding Sealer Without Cutting Though The Edges.

When hand sanding a stain and sealer work piece one must always be careful of the edges to not sand through and white line the work piece. Flap wheels are designed to handle this fine sanding without removing the sealer and causing burn through or white lines in the finish. In a study completed in Germany it was found that most woodworking shops hand sanding removed too much sealer and had to repair many pieces prior to top coat. By using the flap wheel sanding approach you achieve the correct amount of sealer scuffing to create a superb bond with the top coat without white lining or burning through the stain. This will give your product better protection for the future.

5. Reduce Hand Sanding

The speed of sanding with a flap wheel compared to hand sanding is just incredible. Studies show that using a spindle and a flap wheel are more than 10 times faster than hand sanding. This frees you up to do more or other things. The quality of the sand is many times better than a hand sanding as it will always be uniform.

These flap wheels can be used on any spindle from 2″ to 36″ in length and can be used on any arbor that your spindle might have from 1/4″ to 2″.

Save yourself the time of hand sanding and know that the product you create is protected with a superior and uniform finish with excellent quality.
