hi roger the big apple is certainly a lot busier than copenhagen is she happy with the switch.i had a look at that screw fix catalogue thay just about sell every thing.

I have my hands full this weekend wife is working and so im running around after my two boys,at 3 and 2 thay can get up to all sorts,and i hate to just sit them in front off the box,I did manage to paint  the last coat to the cieling and then i need to add coveing wooden ,something small.cant quite remember what thats is called in english,ill prepaint it and pin it up with my nail gun.

i am a bit off a horder and about 7 years ago i bought a mirror picture of a watermill,i plan to frame it an lead in the jionts with lead srtip bought in b&Q 4 yrs ago, at last my little idea will see the light.it should look nice when finished.

so you can tell im doing a little here and there ,i need to attach my sawdust collection unit too my thicknesser jionter  i have a 4" hose but the plastic flu that came with the sander does not seem to be effective or ive got it in the wrong place.im a sheet metal worker so i have the expierience to make some thing that will work.but i dont have a lot off woodworking experience and the picture brochure is off a different machine so it,s a bit off try and see at the moment.

nice to chat hope thats ok here.all the best richard.

Hi Richard

What type of Extractor do you have? Also what Planer do you have?   If it has a 42 hose it should be capable of clearing the chippings from the machine. Although on my machine some of the chippings do escape below the cutter especially when I am Surface planing as opposed to thicknessing,

If you have a photo of your set up send it to this email address roger.ball@boltblue.com and I will have a look and see if I can help.

Regards

Roger

Hi Sam,

 I think the DX4000 is the one with the twin motors?
If so, if I recall correctly, Record used to state that using both motors its designed for a 4in/100mm pipe, but if you link it to narrower bore such as 50mm/2in or small bore hose for routers, sanders etc, then you should only use one motor as the suction power is too much for the smaller bore hose and it will overload the unit.

hope this helps.

Oops! Just read the question again. If you are using a planer thicknesser, a bigger bore 100mm etc is best as the airflow is increased so more efficient. A bigger bore is best if the extractor airflow allows it, so i'd look at a 100mm pipework with maybe a reducer to 50mm on a blastgate for the sander router etc, using one motor as recommended by Record for this purpose.
I have a 63mm pipe system in my workshop which is fine for thicknessing narrower boards or jointing  but working a thicker cut often overwhelms the pipe and it blocks around the planer dust port, especially on pine with sharp knifes.
Ideally, the planer would be best kept as close as possible to the extractor with minimal bends or pipe runs for the best results.

I used Grey Waste pipe 100mm dia for my extraction system similar in principal to Keith Smith's in the latest Woodworker. My blastgates are high attached to the high main pipe. All the Hoses connecting machines either 50 mm or 100 mm go to the high pipe. I rewired the Record Extractor to allow the switches to be in the workshop not on the extractor in the dust collection shed outside the workshop. I used the Axminster plastic Blast gates they were cheap and work well. Several years on and there is no significant wear. I did put a screw access plate on the end of the pipe sp it could be roded out in case of a blockage. The one place where I did have a problem was at the collection end I had 2 90 deg elbows. The first turned from a horizontal feed to vertical and the second bach to horizontal. I found that if the extractor was getting full I could get a back up of shavings and dust so the Lower Elbow was replaced with one which has a roding port. Problem solved

If you put "extraction" in the "search forum" box at the top of this thread, & change the other box to "titles", you`ll find quite a lot of info thats already been discussed.

If i`m trying to teach you to suck eggs & you`ve already done this, my apologies.

hi sad sam,im new to this site and am very new to threads  and stuff.with reference to the book. the workshopbook i also tried to order it from my local libary here in denmark but the copy we had has gone missing.we saw that a second hand copy can be purchased from amozon.com at around a fiver money well spent. im going to check my self out a copy but the vat here cranks the price up soill have to pay 4 times the price.

the book was written in 1991 but is still in print just.

i seem to remember something about static electricity being dangerous  and there has to be good earthing but this must be normal with metal work in the workshop.

that serch forum has to be good try eh.regards richard.

Hi Richard

Welcome to the Forum. Yes you are right Static electricity can cause an explosion when dust is present. However I have never heard of a Woodworking shop having been blown up. I have heard of problems in Flower Mills and places where there is a lot of very fine powder. Having said that If you use a metal pipe and ground it that is the perfect system. Most of us use plastic pipes, the way to earth the system is to run a bare copper wire through the inside of the pipe work and ground it. That will make certain that any build up of static is not allowed to happen.

Any questions please ask.

Good luck

Roger

If you Google a company called "Screwfix" They sell the Roding Port.

Here is a Link   http://www.screwfix.com/prods/11971/Plumbing/Soil-Vent/92-5-Access-Bend-Grey  

The inside of the screw cap has a fairing which stops a build up of dust etc on the curve.

I used one of these of allow me to clear any blockage just before the dust and chippings leave the workshop and enter the collection system in a small shed outside the workshop.

I also used an end cap to allow roding down the main pipe

Here is a link for the end cap   http://www.screwfix.com/prods/16026/Plumbing/Soil-Vent/Screw-On-End-Cap-Grey

I hope this helps. I dont know what materials are available in Denmark but I guess there must be something on these lines.

Good luck on the search.
