Elu Sander Dust Extraction

[tigerturnings]

I picked up a beautiful old Elu orbital sander (model no. has worn off but I think it might be an VS71 or similar - looks like it went on to become the late DW636) a while back and have been impressed with it.

When I recently got hold of a decent dust extractor I decided to hook it up and found when using punched paper the extraction was excellent - while it lasted. The problem seems to be that the dust port is attached to the casting of the baseplate, and thus oscillates, which has worn out my vacuum adapter:



Has anyone solved this problem without replacing the sander? Is there any super-robust vac adapter that'll take the vibration (the one pictured was an Axminster)?

How about a short length of flexible hose between the vibration plate and something fixed to the motor and then into an adaptor. It is quite important to keep the small bore hose as short as possible as the air friction in this will detract from the extraction performance. What size bore hose would you need, I have some odds and ends that might suit and that I could send you.

as bob says

Cheers for the replies. After reading the suggestions I recalled stashing away a load of flexible hose we used to use as a solar heater, and have just found that it's a pretty good tight fit over the Elu's extraction port (for the record, it's about 27mm o/d but the ridges are 2mm high so measures roughly 29mm in the vertical direction). I'll see about securing a piece to the motor casing or maybe the handle soon, and hopefully problem solved.

Thanks for the welcome, too. I've been lurking since the early days of this forum, but haven't had much chance to post. I guess I ought to have introduced myself earlier but in brief I'm a hobbyist, doing mainly turnings and some simple "flat" work. I'm also a uni student and have a part time job in electricity metering, so woodwork time is limited

I think the old power tools are great, they often feel better engineered than their modern counterparts and if I am patient I can buy them pretty cheaply too.

Cheers
