I'm in the market for a DD sanding table for sanding primer/sealer on cab parts and I'm looking for recommendations (store bought? brand? should I make one? ect...?). One man shop, average 200-300 cab parts finished per week. 110 would be ideal but I do have 220 single & 3 phase in the shop. Thank you.
have you checked out the mirka deros or similar sanders that are vacuumed? May be a better fit for your needs and the salesman will more than likely leave a unit with you to demo. We dont have any but we have demoed the mirka and i was very impressed! They do a fantastic job of capturing ALL dust.
Mirka Deros/vacuum, a Surfprep set up AND a Sandman table (110v/220v) with lights. Make yourself a box to clean your filters that hooks to dust collection, or you'll negate the point of the downdraft table and abuse the blower motor.
If you really want a game changer and you are looking to grow significantly in the near future, (we are only a 6-10 man shop) get at least a 3 head 53" programmable sander with combi head equipped for sealer sanding. You're head will just about explode when you add up the time spent previously and when you see the finish improvements. Between pre-sanding all parts and sealer sanding, switching to paper belts and the extended abrasive life, this is one of the fastest paybacks we've had on a major macchine purchase, Not to mention the quantum leap in finish quality and overall speed gains over our old 37"- 2 head machine.
Also, the 5" mesh sanding discs when used with vacuum will last a ridiculous long time compared to the PSA discs to the point where they become dull rather than plugged.
If you haven't done so already, please take a sanding and or finishing seminar at IWF or AWFS. Sanding can make or break your profits and quality consistency.
Over-sanding is probably the bigger robbers of profit and quality in a custom shop that does a lot of finishing. Swirls, color inconsistency, cross scratch, uneven areas between dissimilar materials and polished burnished grain are the sins of woodworking and finishing.
So to answer your question, to start with, I'd buy any one of the commercially made downdraft table, it's not worth the time to make one in my opinion, as I'd rather be putting that time into growing my company. I'd continue to get a set of lights, the best sanders and vacuums money can buy. Oil your sanders daily and don't cheap out on sealers/primers, abrasives and topcoats and you'll move ahead much faster.
yes, l looked at the denray tables online as they came highly recommended by one of my customers. My local dealer (300+ miles away)has yet to get back to me with a price. but by the specs and reputation l'm guessing they're at the higher end price wise. l can get a pretty good deal on the small Baleigh table and l'm wondering how they compare...I've learned (reluctantly) that it pays to buy quality but sometimes (once in a blue moon) a bargain really is one.
comes down to airflow that each table has and wheter it has cheap blanket filters and final filters or whether it has cartridge or tube style filters, imho, denray makes a much beefer table,also rpm of exhaust motor
ended up not getting the denray as a customer had a almost new 1hp Delta for $400.00. It's 1/3 the machine of the denray but at 1/7 cost l couldn't pass it up. lt is working great for my application; sanding sealer and scuffing frame & panel cabinet doors and drawers (l use a festool for the larger pieces and the flats). there is noticibly less dust in the room where l sand and lots in the delta's filter.

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).
