Frequently Asked Questions

How do I fill the slip trailer bag?

Fill a washing-up liquid bottle with the slip of your choice. Slide the slip trailer barrel out from its black rubber bung, then fill up the latex slip trailer bag almost to the top with slip from your bottle. Squeeze the bag gently till the slip expels all of the air from the bag, while you reinsert the barrel. Twist the stainless steel tip of your choice onto the barrel, and decorate.

Does the slip trailer splutter and spit?

No, because you expel air from the latex bag when filling (see above), you get no spluttering or spitting.  Because the latex bag is soft, it self-seals and cannot draw air back down into the bag through the tip.

How do I change the stainless steel tips?

A simple twist to the left will unlock the tip. To tighten, turn to the right. All the tips have the same collar size, so fit snugly onto the slip trailer barrel.

If the stainless steel tips get blocked how do I clear them?

There are 3 cleaning pins and a high-pressure water flushing syringe included with The Mark Dally Slip Trailer©.

Twist off the blocked tip and immerse in water.  Fill the flushing syringe with water, insert into tip collar, and force the plunger down hard; the jet of water will flush out any blockage in the tip. If this does not work after a couple of tries, use the cleaning pins. The smaller tips can become blocked more easily, so push the fine or superfine cleaning pin down the end of the tip's tube to dislodge any blockage. Follow with a syringe flush of water. Typically, the larger tips only need a flush of water from the syringe.

Received The Mark Dally Slip Trailer for xmas from my son. Have to say that I love it! A wonderful gadget easy to use and effective. Smashing product and although I thought it was pricey to start with, it’s all good quality stuff. Would have cost much more than that here in Norway. Seriously, sat with a smile on my face using it, its very comfortable and easy to use and no splodging at all. What a fabulous addition it is to my workbox!  just so pleased with it.    J A Clark, Norway

Once I was used to using the slip trailer it became a delight to operate. You can get a high degree of accuracy with it, as you can hold it like a pen and it solves my gripes with previous slip trailers I have bought, in that it doesn’t splodge and doesn’t cause your hands to ache. In short it is the best slip trailer I have used and I suspect the best slip trailer that you can purchase today.

I found once the trailer was filled and all the air expelled, air was never sucked back into the trailer, which meant absolutely no splodging of slip and no having to prime the trailer by squeezing out any air before going onto the pot.   Lee Cartledge, Bentham Pottery, UK

Loving having a play, thank you so much. Did this drawing of the Six Sisters in Napier NZ on a curved salad bowl ! You made the latex bladder to fit my hand size and it's just great. So comfortable to use.

Thank you.   Lynda Renner, New Zealand

I love it because it fits my size hands and gives lovely accurate slip trailing. It’s easy to put together and easy to clean. It’s a great product and a long awaited update of a Potters staple tool.    Elaine Wells, UK

Your slip trailer delivers a steady flow at a good rate. Holding an ordinary hard rubber trailer steady is not that easy for me, so the softness and pliability of yours is far better. I have not used all the nozzles yet, but thus far have been very impressed with it.   JJ, UK
