Pods on top of spoilboard


I recently toured a large cabinet door shop, and saw that they do final sizing of all doors on a pod and rail CNC. trimmng about 1mm on all sides, climb cutting with what I assume is a chipbreaker style compression bit (didn't get a good look at tooling). I always thought that big shops were using a double end tenoner for this process, but I guess that's the old school way now.

We have recently started making our own 5 piece doors, sizing all parts to finished dimensions prior to assembly and then edge sanding after glue up. This works ok, but sometimes requires quite a bit of fine tuning especially on inset jobs.

I would like to route my doors to finish size on my flat table cnc, but I'm thinking this would require pods. Are any of you doing an operation like this using pods on top of a spoilboard? Do the pods have their own vacuum pump, or do you use the cnc's pump? Thanks

I use pods on my spoil board and use a small vacuum pump. You really don't need a huge pump to hold smaller stuff

as jerry states a small vacuum will hold alot.

take a look at a SMC ZH, Vacuum Generator. it uses your compressed air to pull a vacuum. we use them on a ton of hold down projects & to date we have never lost a part due to hold down issues.

You can try this flat CNC table use vacuum pods if you have interests.

Made in the USA, BVC Vacuum Pods for MDF spoil board applications.

I am wondering why you need pods? Why donít you just set your door directly on the spoil board and size it that way.
Maybe you donít have enough vacuum with your set up.

With pods you can profile the edges

You can size the door and profile the top side while sitting on the spoil board and hit the back side with a laminate trimmer while sanding if the back side needs a profile.
Seems like a lot of added expense to get cups and a seperate vacuum pump .
I guess maybe I am cheap.😳

What kind of router ?

Most will accept pods on the machine bed, no need to get the spoilboard involved.

It uses the CNC vac pump to feed through the pod and you use your locator pins to position the part.

If you don't have that capability don't try, just order your doors and keep to cutting parts.

IMHO I could not ever make money making doors, I would need at bare minimum a couple shape and sand machine a cope machine , a door clamp carrier and a 75 k + sander, a moulder, a room full of profile insert cutter heads etc etc.. and another 3000 sq feet to do it all.

Just thinking about it makes me go bankrupt, yup Ill just keep buying doors.....

My router is a format4 H08. It does have a matrix table and pop up pins but we screw our spoilboard to the phenolic so taking it on and off is pretty annoying.

I hear what youíre saying re making doors in house, but honestly itís been great for us. We were already making MDF doors and dovetail drawers, so this was the last thing we outsourced. I love being able to have the doors when I need them, as well as being able to do any other specialty rail and stile work ( island back panels etc.) that tends to get extremely expensive when purchased from a door supplier.

Not arguing against outsourcing.. we did for a long time and it makes sense for a lot of shops.

So are you doing just a few styles of door and panel and edge profiles, or did you get a lot of cutters ?

I give my customers the catalogue from my supplier and just let them choose.

What is your finish schedule for the MDF doors ? ESP sanding schedule ?

One of my hang ups in the past with MDF doors was the finishing and keeping them flat.

Also do you run flip side machining on the MDF doors to simulate a panel or are they just flat on the back ?

What is your setup for running the five piece doors.

Our supplier drops them two weeks after we order so we just figure that into the lead time and it works well. The end panels do get expensive like you stated however.

We have a full filtered spray booth with makeup air now so maybe itís time to try the MDF doors again.

We do the drawer boxes on the CNC with baltic birch. Sides 1/8 less tall than fronts and backs , through the shaper to radius ,then gang stack and spray top edge before assembly.

    WOODWEB's forums are a highly regarded resource for professional woodworkers. Messages and responses that are crafted in a professional and civil manner strengthen this resource. Messages that do not reflect a professional tone reduce the value of our forums.

    Messages are inappropriate when their content: is deemed libelous in nature or is based on rumor, fails to meet basic standards of decorum, contains blatant advertising or inappropriate emphasis on self promotion (return to top).

    Libel:   Posts which defame an individual or organization, or employ a tone which can be viewed as malicious in nature. Words, pictures, or cartoons which expose a person or organization to public hatred, shame, disgrace, or ridicule, or induce an ill opinion of a person or organization, are libelous.

    Improper Decorum:   Posts which are profane, inciting, disrespectful or uncivil in tone, or maliciously worded. This also includes the venting of unsubstantiated opinions. Such messages do little to illuminate a given topic, and often have the opposite effect. Constructive criticism is acceptable (return to top).

    Advertising:   The purpose of WOODWEB Forums is to provide answers, not an advertising venue. Companies participating in a Forum discussion should provide specific answers to posted questions. WOODWEB suggests that businesses include an appropriately crafted signature in order to identify their company. A well meaning post that seems to be on-topic but contains a product reference may do your business more harm than good in the Forum environment. Forum users may perceive your references to specific products as unsolicited advertising (spam) and consciously avoid your web site or services. A well-crafted signature is an appropriate way to advertise your services that will not offend potential customers. Signatures should be limited to 4-6 lines, and may contain information that identifies the type of business you're in, your URL and email address (return to top).

    Repeated Forum Abuse: Forum participants who repeatedly fail to follow WOODWEB's Forum Guidelines may encounter difficulty when attempting to post messages.

    There are often situations when the original message asks for opinions: "What is the best widget for my type of shop?". To a certain extent, the person posting the message is responsible for including specific questions within the message. An open ended question (like the one above) invites responses that may read as sales pitches. WOODWEB suggests that companies responding to such a question provide detailed and substantive replies rather than responses that read as a one-sided product promotion. It has been WOODWEB's experience that substantive responses are held in higher regard by our readers (return to top).
